BJ’s Deep Dish Ziti Recipe (Copycat Brewhouse Pasta)

I still remember the first time I ordered BJ’s Deep Dish Ziti – it arrived at the table in a sizzling cast iron skillet, the mozzarella still bubbling, with marinara pooling around the edges like a little moat of tomato heaven. I sat there for a second just staring at it before my fork even moved. That first bite hit every note: creamy ricotta, robust marinara, tender ziti, and that pull of melted mozzarella that stretches halfway across the table. I went home that night absolutely determined to recreate it, and I tested this recipe four times before I was truly happy with it.

What makes BJ’s version different from a standard baked ziti is the sheer density and depth. They layer it thick, they don’t hold back on the cheese, and baking it in a cast iron skillet creates those crispy, caramelized edges that you just cannot get from a casserole dish. This copycat nails all of that. Once you make it this way, you will never go back to the baking dish version.

Why You’ll Love This Recipe

• The cast iron skillet gives you those irresistible crispy, caramelized cheese edges you can never get from a regular baking dish.
• Three cheeses – ricotta, mozzarella, and Parmesan – create a depth of flavor that tastes like a real Italian-American restaurant at home.
• It reheats beautifully, so leftovers are just as good the next day with a little extra sauce on top.
• The recipe is completely customizable – swap in Italian sausage, add spinach, or go vegetarian with roasted mushrooms.
• One skillet means fewer dishes, and the dramatic tableside presentation makes it feel genuinely special for a weeknight dinner.

About This Multi-Brand Favorite

BJ’s Restaurants and Brewhouse built its menu around the idea that casual dining should still feel indulgent. Their Deep Dish Ziti has been a staple on the pasta menu for years, and it earns its place by being unapologetically generous – thick layers of pasta, a rich and well-seasoned marinara, scoops of creamy ricotta, and a blanket of mozzarella that gets broiled until it has those gorgeous golden-brown spots on top. The cast iron skillet is the real secret weapon here. It holds heat so intensely that the bottom and sides of the pasta actually caramelize slightly, giving the whole dish a texture contrast that a standard casserole simply cannot deliver. It is the kind of pasta that makes you slow down and actually enjoy every single bite.

Ingredients

For the deep dish ziti

• 1 lb (450g) ziti pasta
• 2 tablespoons olive oil
• 4 garlic cloves, minced
• 1 lb (450g) ground Italian sausage (sweet or hot)
• 1 teaspoon dried oregano
• 1 teaspoon dried basil
• 1/2 teaspoon red pepper flakes
• Salt and black pepper to taste
• 15 oz (425g) whole-milk ricotta cheese
• 1 large egg
• 2 cups shredded whole-milk mozzarella cheese, divided
• 1/2 cup grated Parmesan cheese, divided

For the cheese topping

• 2 tablespoons olive oil
• 1 medium yellow onion, finely diced
• 4 garlic cloves, minced
• 1 can (28 oz) crushed San Marzano tomatoes
• 1 can (14 oz) diced tomatoes
• 1 teaspoon sugar
• 1 teaspoon dried Italian seasoning
• Salt and black pepper to taste

Ingredient Substitutions

• Ground beef or turkey can replace the Italian sausage for a leaner version.
• Part-skim ricotta works fine if that is what you have, though whole-milk gives a creamier texture.
• Penne or rigatoni are great stand-ins if ziti is unavailable – they hold sauce just as well.
• Jarred marinara (a good quality one like Rao’s) can replace the homemade sauce when you are short on time.
• Provolone can be layered in alongside the mozzarella for an even stretchier, more flavorful cheese pull.

Equipment You’ll Need

• 12-inch cast iron skillet
• Large pot for boiling pasta
• Colander
• Large mixing bowl
• Wooden spoon or silicone spatula
• Oven mitts (cast iron gets very hot)

Step-by-Step Instructions

1. Make the marinara sauce. Heat 2 tablespoons of olive oil in a medium saucepan over medium heat. Add the diced onion and cook for about 5 minutes until softened and translucent. Stir in the minced garlic and cook for 1 minute more until fragrant. Pour in the crushed and diced tomatoes, add the sugar, Italian seasoning, salt, and pepper. Stir everything together and let it simmer on low heat for at least 20 minutes, stirring occasionally, until the sauce thickens and the flavors meld. Taste and adjust seasoning. Set aside.
2. Cook the pasta and meat. Bring a large pot of salted water to a boil and cook the ziti for 2 minutes less than the package directions – you want it very al dente since it will finish cooking in the oven. Drain and toss with a little olive oil to prevent sticking. Meanwhile, in your 12-inch cast iron skillet, heat 2 tablespoons of olive oil over medium-high heat. Add the Italian sausage and break it apart as it cooks. Once browned, add the minced garlic, oregano, basil, and red pepper flakes. Season with salt and pepper. Cook for 2 more minutes, then remove the sausage mixture and set aside, leaving the flavorful drippings in the skillet.
3. Mix the ricotta layer. In a large mixing bowl, combine the ricotta cheese, egg, half of the Parmesan, and a good pinch of salt and pepper. Stir until smooth and well combined. The egg helps the ricotta hold together during baking and gives it that creamy, sliceable texture rather than crumbling apart. This step only takes a couple of minutes but makes a real difference in the final texture of the dish.
4. Layer the ziti in the skillet. Preheat your oven to 375 degrees F (190 degrees C). Leave those drippings in the cast iron skillet – that fat is pure flavor. Spread a generous layer of marinara across the bottom of the skillet. Add half the cooked ziti, spread half the sausage mixture over it, then drop spoonfuls of the ricotta mixture across the top. Scatter 1 cup of mozzarella over the ricotta. Repeat: more marinara, remaining ziti, remaining sausage, remaining marinara, the rest of the mozzarella, and a final shower of Parmesan across the top.
5. Bake until bubbly and golden. Cover the skillet tightly with aluminum foil and bake for 25 minutes. Remove the foil and continue baking for another 10-15 minutes until the cheese on top is melted, golden, and has those beautiful caramelized spots that are the signature of BJ’s version. If you want even more color on top, switch to the broiler for the last 2-3 minutes, keeping a close eye on it so it doesn’t burn. The edges should be pulling away slightly from the skillet and the cheese should be deeply golden.
6. Rest and serve. This step is important – let the ziti rest in the skillet for at least 10 minutes before serving. This allows the layers to set up so they hold together when you scoop them out, and it lets the skillet cool down enough to handle safely (though please use those oven mitts – cast iron holds heat for a long time). Garnish with fresh basil leaves and an extra sprinkle of Parmesan. Serve directly from the skillet at the table for that full BJ’s experience.

Pro Tips from My Kitchen

• Salt your pasta water generously – it should taste like the sea. Properly seasoned pasta is the foundation of any great pasta dish.
• Undercook your ziti by 2 full minutes. It finishes in the oven and overcooked pasta turns mushy after baking. Err on the side of too firm.
• Let the skillet get really hot before you start cooking the sausage. That high heat creates the caramelized drippings that flavor the whole dish.
• Use whole-milk ricotta and whole-milk mozzarella. Low-fat versions release too much water during baking and make the dish watery and less rich.
• If your sauce tastes acidic, add a tiny pinch of sugar or a small knob of butter at the end. San Marzano tomatoes are naturally sweeter but even they can vary.
• For the crispiest edges possible, make sure your skillet is well-seasoned. If yours tends to stick, rub a thin layer of olive oil on the sides before layering.

Recipe Variations

• Vegetable Deep Dish Ziti: Skip the meat entirely and layer in roasted zucchini, eggplant, and bell peppers for a hearty meatless version.
• Spicy Arrabbiata Ziti: Use hot Italian sausage, double the red pepper flakes in the sauce, and add a teaspoon of calabrian chili paste for real heat.
• White Sauce Version: Replace the marinara with a homemade bechamel and add roasted garlic for a creamy, elegant twist.
• Chicken Sausage Ziti: Substitute chicken sausage for pork sausage to lighten it up while keeping all the Italian seasoning flavor.
• Four Cheese Ziti: Add a layer of fontina and provolone alongside the mozzarella for an ultra-indulgent, seriously cheesy version.

Common Mistakes to Avoid

• Not salting the pasta water: Unseasoned pasta tastes flat no matter how good your sauce is. Salt the water properly every single time.
• Overcooking the pasta before baking: If you cook it to package directions, it will be mushy after 40 minutes in the oven. Stop 2 minutes early.
• Skipping the resting period: Cutting into it immediately makes the layers fall apart and the sauce pour all over the plate. Ten minutes of patience pays off.
• Using cold ricotta straight from the fridge: Cold ricotta doesn’t blend smoothly and can create cold spots in the bake. Let it come to room temperature first.
• Covering the dish for the entire baking time: The foil is needed at first to trap steam and cook through, but removing it at the end is essential for golden, bubbly cheese on top.

What to Serve With This Dish

• Garlic bread or a crusty Italian baguette for scooping up extra marinara sauce
• A simple Caesar salad to cut through the richness of the cheese
• Steamed or roasted broccoli with lemon and Parmesan
• A glass of Chianti or a medium-bodied Italian red wine
• Minestrone soup as a light starter before the rich main

Storage Instructions

Refrigerator

Store leftovers covered tightly in the skillet or transferred to an airtight container. Keeps well for up to 4 days in the refrigerator.

Freezer

Freeze individual portions in airtight freezer-safe containers for up to 3 months. Add a spoonful of extra marinara on top before freezing to keep it moist.

How to Reheat

Reheat in a 350 degree F oven covered with foil for 15-20 minutes, or microwave individual portions with a splash of water and a loose covering to prevent drying out. The oven method keeps the edges crisper.

Make Ahead

You can fully assemble the ziti up to 24 hours ahead, cover the skillet tightly, and refrigerate. Add 10-15 minutes to the covered baking time when cooking from cold.

Frequently Asked Questions

Can I make this without a cast iron skillet?

Yes, you can use a 9×13 inch baking dish instead. You won’t get the same crispy caramelized edges, but the flavor will still be excellent. Increase the covered baking time by about 5 minutes since glass and ceramic don’t conduct heat as efficiently as cast iron.

What size cast iron skillet works best for this recipe?

A 12-inch cast iron skillet is ideal and gives you the best depth and crust ratio. A 10-inch works too but the layers will be taller and may need 5 extra minutes of baking time covered.

Can I use jarred marinara sauce to save time?

Absolutely. A good quality jarred marinara like Rao’s Homemade or Victoria is a great shortcut. Use about 24 oz total. The homemade version has more depth but jarred sauce still makes a delicious dish.

How do I know when the ziti is fully cooked and done baking?

The cheese on top should be deeply golden with some caramelized spots, and the sauce should be actively bubbling around the edges. Insert a knife in the center – it should come out hot to the touch.

Can I make this recipe vegetarian?

Yes, simply omit the Italian sausage and add more vegetables like roasted mushrooms, diced bell peppers, or sauteed spinach. You still get an incredibly hearty and satisfying dish without the meat.

Why does my ziti come out watery?

Two common culprits: the pasta was overcooked and released starch water, or the ricotta and mozzarella were low-fat varieties that release more moisture during baking. Stick to whole-milk dairy and undercook the pasta.

Can I double this recipe?

You would need two 12-inch skillets or one very large roasting pan. Don’t try to cram double the amount into one skillet – the layers get too deep and the center won’t cook through properly.

What is the best pasta shape if I can’t find ziti?

Penne rigate is the closest substitute – similar length and the ridges hold sauce beautifully. Rigatoni also works great and some people actually prefer it because the larger tubes collect even more cheese inside them.

Can I add spinach to this recipe?

Yes and it is a great addition. Wilt about 3 cups of fresh spinach in a pan with a little garlic, squeeze out all the excess water, then mix it into the ricotta layer. It adds color, nutrition, and a mild flavor that complements the cheese.

How far ahead can I assemble this before baking?

You can fully assemble it, cover tightly, and refrigerate for up to 24 hours before baking. This actually helps the flavors meld together. Just add 10-15 minutes to the initial covered baking time since it starts cold.

Is BJ’s deep dish ziti the same as regular baked ziti?

They are similar but BJ’s version is denser, richer, and baked in a cast iron skillet which creates those signature crispy caramelized edges. The cast iron also keeps it hotter longer at the table, and the depth of layering is more substantial than most home versions.

Can I freeze this after baking?

Yes, it freezes very well. Let it cool completely, portion into freezer-safe containers, and add a spoonful of extra marinara on top to keep it moist. Freeze for up to 3 months and reheat covered in a 350 degree oven.
