Red Lobster Salmon New Orleans Recipe (Copycat Cajun)

I have been obsessed with Red Lobster’s Salmon New Orleans for years – that perfectly seared fillet crowned with plump, garlicky shrimp in a smoky Cajun butter sauce is honestly one of the best things on their entire menu. After way too many restaurant visits trying to figure out exactly what made it so addictive, I finally cracked the code in my own kitchen. The secret is a hot cast iron pan that gives you that gorgeous crust, paired with a quick pan sauce that comes together in the same skillet using butter, garlic, cream, and just the right blend of Cajun spices. This is the recipe I make when I want to impress someone without spending hours cooking, and every single time people ask me if I ordered it from the restaurant.

This copycat Red Lobster Salmon New Orleans is a surf-and-turf dream on a single plate. Cajun seasoning delivers that signature smoky heat, the shrimp cook in minutes, and the buttery pan sauce ties everything together beautifully. You will have dinner on the table in 25 minutes flat.

Why You’ll Love This Recipe

• Restaurant quality at home for a fraction of the price – this dish runs $25+ at Red Lobster, and you can feed four for less than that total
• One skillet from start to finish, which means less cleanup and more flavor since the shrimp butter sauce picks up all those gorgeous browned bits left behind by the salmon
• Ready in just 25 minutes, making it fast enough for a weeknight but impressive enough for a dinner party or special occasion
• Completely customizable heat level – dial the cayenne up or down depending on who you are feeding, and it always turns out perfectly balanced
• The Cajun shrimp topping doubles as a sauce, so every bite of salmon is coated in that smoky, garlicky, creamy goodness that makes this dish so memorable

About This Red Lobster Favorite

Red Lobster’s Salmon New Orleans has been one of the chain’s most popular entrees for good reason. The dish takes their wood-fire grilled salmon concept and elevates it dramatically by topping the fillet with sauteed shrimp swimming in a Cajun-spiced butter sauce, creating an indulgent surf-and-turf combination that feels far more upscale than a casual seafood chain typically delivers. The name nods to the bold Creole cooking traditions of New Orleans – that vibrant culinary culture built on the holy trinity of onion, celery, and bell pepper, rich butter sauces, and the kind of spice blends that warm you from the inside out. Cajun seasoning, a cornerstone of Louisiana cooking, brings paprika, garlic powder, onion powder, oregano, thyme, and cayenne together into the backbone of the dish. What makes the Red Lobster version so craveable is the contrast – lean, flaky salmon against buttery, tender shrimp, clean citrus brightness against smoky heat, and the slight richness of cream and Parmesan pulling everything into a cohesive sauce that clings to every bite.

Ingredients

For the salmon

• 4 salmon fillets (6 oz each), skin on or off
• 2 tablespoons Cajun seasoning
• 2 tablespoons olive oil
• 1 tablespoon butter
• 1 teaspoon salt
• 1/2 teaspoon black pepper
• 1 lemon, juiced, for finishing
• 1 tablespoon fresh dill, chopped

For the Cajun shrimp butter topping

• 1 lb medium shrimp, peeled and deveined
• 6 tablespoons unsalted butter
• 4 cloves garlic, minced
• 1 teaspoon Cajun seasoning
• 1/2 teaspoon paprika
• 1/4 teaspoon cayenne pepper
• 1/4 cup dry white wine or chicken broth
• 2 tablespoons fresh lemon juice
• 1/4 cup heavy cream
• 1/4 cup Parmesan cheese, freshly grated

For finishing

• Fresh parsley, chopped
• Lemon wedges
• Fresh chives, snipped
• Capers (optional, for a briny finishing touch)

Ingredient Substitutions

• Frozen salmon works perfectly – just thaw it completely in the refrigerator overnight and pat very dry before seasoning
• Skip the shrimp entirely and make blackened salmon only – still incredible with just the Cajun butter drizzled on top
• No white wine in the house – chicken broth or even seafood stock works just as well in the sauce
• Dairy-free version – swap the heavy cream for full-fat coconut cream and skip the Parmesan, the sauce is still rich and delicious
• Instant Pot option – cook the seasoned salmon on high pressure for 8 minutes with a cup of broth, then make the shrimp sauce separately in a skillet

Equipment You’ll Need

• Large cast iron skillet or oven-safe heavy-bottomed pan (12 inch recommended)
• Fish spatula for flipping without breaking the fillet
• Small saucepan or the same skillet for the butter sauce
• Tongs for handling shrimp in the sauce
• Instant-read thermometer to hit the perfect 145F internal temp

Step-by-Step Instructions

1. Season the salmon. Pat all four salmon fillets completely dry with paper towels – this is the single most important step for getting a proper sear. Any moisture on the surface will steam the fish instead of browning it. Once dry, sprinkle each fillet evenly with the Cajun seasoning, salt, and black pepper, pressing gently so the spices adhere. Let the seasoned salmon sit at room temperature for about 5 minutes while you heat your pan.
2. Sear the salmon. Heat the olive oil and butter in a large cast iron skillet over medium-high heat until the oil is shimmering and just starting to smoke – about 2 minutes. Place the salmon fillets skin-side down in the pan without moving them. Sear for 4 minutes undisturbed until the skin is crispy and the edges look cooked halfway up. Flip carefully with a fish spatula and cook the other side for 2 to 3 minutes until the internal temperature reaches 145F. Transfer to a plate and tent loosely with foil to rest.
3. Cook the shrimp. In the same skillet over medium heat, melt 3 tablespoons of the butter. Add the minced garlic and saute for 30 seconds until fragrant. Add the shrimp in a single layer, then sprinkle with Cajun seasoning, paprika, and cayenne. Cook 1.5 minutes per side until the shrimp are pink and just curled – do not overcook or they will become rubbery. Remove shrimp to the plate with the salmon.
4. Build the Cajun butter sauce. With the heat still on medium, add the white wine and lemon juice to deglaze the skillet, scraping up all the browned bits from the bottom – that is where all the flavor lives. Let it bubble for 30 seconds, then pour in the heavy cream. Whisk in the remaining 3 tablespoons of butter one tablespoon at a time, then stir in the grated Parmesan. Simmer for 2 minutes until the sauce thickens slightly and coats the back of a spoon.
5. Plate and serve. Nestle each salmon fillet on a warm plate. Spoon the sauteed shrimp over the top, then ladle the Cajun butter sauce generously over everything. Finish with a squeeze of fresh lemon juice, a scattering of chopped fresh parsley and chives, and optional capers if using. Serve immediately with your choice of sides and extra lemon wedges on the plate.

Pro Tips from My Kitchen

• Patting the salmon completely dry is non-negotiable – moisture is the enemy of a good sear, and a great crust is what separates this dish from a steamed fillet
• Your pan must be genuinely hot before the salmon goes in – if you place your hand a few inches over the surface and you can feel intense heat, it is ready. A cold pan means the fish sticks and steams rather than sears
• Do not overcook – salmon is done at 145F internal temperature and dries out fast beyond that point. Pull it just as the center turns from translucent to barely opaque
• Rest the salmon for at least 3 minutes before plating – this allows the juices to redistribute so every bite stays moist instead of running out onto the plate
• Use a real Cajun seasoning blend, not just plain paprika – look for brands like Slap Ya Mama, Tony Chachere’s, or Zatarain’s that contain the full mix of spices for authentic flavor
• Finish with fresh lemon juice right before serving – the brightness cuts through the richness of the butter sauce and lifts the whole dish

Recipe Variations

• Outdoor grilled version – season the salmon the same way and grill over medium-high direct heat for 4 minutes per side, then make the shrimp butter sauce indoors in a cast iron pan
• Extra blackened cast iron – crank the heat to high and let the Cajun seasoning genuinely char slightly for a more intense, smoky flavor with a darker crust
• Solo salmon without shrimp – skip the shrimp entirely and just pour the Cajun butter sauce directly over the seared fillet for a simpler but still spectacular dinner
• With andouille sausage added – slice half a pound of andouille into coins and brown them in the skillet before the shrimp for a hearty Louisiana-style version with extra depth
• Crab meat substitution – use lump crab meat instead of shrimp for an even more luxurious topping that feels like a true New Orleans fine-dining experience

Common Mistakes to Avoid

• Starting with a cold pan – the salmon will stick, refuse to release, and steam instead of developing that beautiful golden crust that makes this dish so visually appealing
• Overcooking the salmon past 145F – the fillet goes from perfectly flaky to chalky and dry very quickly, so use a thermometer rather than guessing by time alone
• Skipping the patting dry step – surface moisture creates steam and prevents browning, so even if you are in a rush, take 30 seconds to thoroughly dry the fillets with paper towels
• Flipping the salmon too early – if the fish resists when you try to flip it, it is not ready yet. A properly seared fillet will release naturally from the pan when the crust is set
• Over-salting when using pre-made Cajun seasoning – most commercial Cajun blends already contain significant salt, so taste before adding extra and season conservatively at first

What to Serve With This Dish

• Homemade Cheddar Bay Biscuits – because no Red Lobster meal is complete without them, and they are perfect for soaking up the leftover Cajun butter sauce on the plate
• Dirty rice or creamy jasmine rice – the Cajun flavors pair perfectly with rice, and it soaks up the sauce beautifully so nothing goes to waste
• Roasted asparagus with lemon – the clean, bright flavor of asparagus balances the richness of the butter sauce without competing with the bold Cajun spices
• Southern-style grits with butter and Parmesan – a bowl of creamy grits under the salmon is an absolutely classic New Orleans combination that feels incredibly satisfying
• Simple green salad with lemon vinaigrette – a light, acidic salad cuts through the richness of the dish and keeps the overall meal feeling balanced

Storage Instructions

Refrigerator

Store salmon and shrimp sauce separately in airtight containers for up to 3 days – keeping them separate prevents the sauce from making the salmon soggy

Freezer

Raw salmon fillets freeze well for up to 3 months tightly wrapped; cooked salmon can be frozen but the texture suffers somewhat, so fresh is strongly preferred

How to Reheat

Warm salmon in a 350F oven covered loosely with foil for 8 to 10 minutes to prevent it from drying out; reheat the sauce separately in a small saucepan over low heat

Make Ahead

Season the salmon up to 24 hours in advance and refrigerate uncovered on a rack for even better flavor and a drier surface for searing; make the sauce the day of serving

Frequently Asked Questions

What makes Red Lobster Salmon New Orleans so special compared to other salmon dishes?

The combination of a wood-fire style sear on the salmon with that Cajun shrimp butter topping is what sets it apart. Most salmon dishes are just salmon, but Red Lobster layers in the surf-and-turf element with shrimp, adds the smoky complexity of Cajun spices, and ties everything together with a buttery cream sauce that feels indulgent without being heavy. It is that combination of textures and flavors all on one plate.

What Cajun seasoning brand should I use for the most authentic flavor?

Tony Chachere’s Original Creole Seasoning is my top pick and the most widely available. Slap Ya Mama is another excellent Louisiana brand with great flavor. Zatarain’s Creole Seasoning also works well. If you only have generic grocery store Cajun seasoning, it will still taste good, but those Louisiana-made brands carry a more authentic blend of herbs and heat that really makes a difference.

What internal temperature should salmon reach when it is done?

The USDA recommends 145F for fully cooked salmon. At that temperature the flesh will be opaque and flake easily but still retain moisture. Many home cooks prefer pulling it at 130-135F for a slightly more silky, medium texture, similar to how upscale restaurants serve it. For this recipe I recommend 145F for food safety and classic results, especially if you are serving this to children or anyone immunocompromised.

How many calories are in Red Lobster Salmon New Orleans?

This copycat version comes in at approximately 620 calories per serving with 56 grams of protein, 38 grams of fat, and 6 grams of carbohydrates. The restaurant version tends to run higher due to larger portion sizes and additional butter used in their cooking process. The calorie count here reflects a 6-ounce salmon fillet with the full shrimp butter sauce as written.

Can I make this recipe without the shrimp?

Absolutely – the Cajun-seared salmon stands beautifully on its own. Simply make the Cajun butter sauce without the shrimp, seasoning it with the same garlic, paprika, cayenne, white wine, lemon, cream, and Parmesan, then pour it directly over the seared fillet. You will get all the same flavor notes without the surf-and-turf element. It is slightly simpler and still absolutely delicious.

Is this recipe gluten-free?

Yes, this recipe is naturally gluten-free as written. Just double-check your Cajun seasoning label since some commercial blends contain hidden fillers, and confirm that your chicken broth or white wine is certified gluten-free if you are cooking for someone with celiac disease. All other ingredients – salmon, shrimp, butter, cream, Parmesan, garlic, and lemon – are inherently gluten-free.

Can I freeze the cooked salmon and shrimp?

You can freeze the cooked salmon for up to one month, though the texture will be slightly softer after thawing and reheating compared to freshly made. The cream-based shrimp sauce does not freeze well – it tends to separate and turn grainy when thawed. My recommendation is to freeze only the raw salmon and make the shrimp sauce fresh each time for the best results.

Why does my salmon come out dry instead of flaky and moist?

The two most common culprits are overcooking and skipping the rest period. Salmon turns dry very quickly past 145F, and even a minute or two extra on the heat makes a noticeable difference. Always use an instant-read thermometer rather than relying on time alone. Then let the salmon rest on the plate for 3 full minutes before cutting into it – this step allows the juices to redistribute through the fillet and keeps every bite moist.

What wine should I use in the Cajun butter sauce?

A dry white wine works best – something like Pinot Grigio, Sauvignon Blanc, or an unoaked Chardonnay. The rule of thumb is to use a wine you would actually drink since the flavor concentrates as it cooks down. Avoid sweet wines like Riesling or Moscato as they can make the sauce taste unbalanced. If you prefer not to cook with alcohol, chicken broth or seafood stock is a perfectly good substitute.

What is the difference between blackened and Cajun seasoning?

Cajun seasoning is a spice blend – typically paprika, garlic powder, onion powder, oregano, thyme, cayenne, and black pepper – that you apply to food before cooking. Blackened is a cooking technique where food coated in that spice blend is cooked in a very hot cast iron skillet until the spices char slightly and form a dark, intensely flavored crust. So blackened salmon uses Cajun seasoning but takes the heat much higher to create that characteristic dark exterior.

Does frozen salmon work as well as fresh for this recipe?

Yes, with one important caveat – it must be completely thawed and thoroughly dried before cooking. Thaw frozen salmon overnight in the refrigerator, never on the counter. Once thawed, pat it dry very aggressively with paper towels, more than you think is necessary. Frozen-and-thawed salmon releases more moisture than fresh, so extra drying is essential to achieve a proper sear. The flavor difference is minimal when cooked this way.

What sides does Red Lobster actually serve with Salmon New Orleans?

At Red Lobster, Salmon New Orleans typically comes with a choice of two sides from their menu including options like mashed potatoes, broccoli, rice pilaf, coleslaw, or a garden salad, plus their signature Cheddar Bay Biscuits on the table. At home I love serving this with creamy grits or dirty rice to lean into the New Orleans theme, roasted asparagus or broccoli for something green, and of course a batch of homemade Cheddar Bay Biscuits for the full experience.
