If you’ve stood in the grocery store wondering whether kale and spinach are basically the same thing, you’re not alone. Here’s what I have learned cooking with both.
Quick Answer
Both excellent greens. Spinach for soft uses (omelets, salads, smoothies). Kale for hearty applications (chips, massaged salads, holding up to cooking). Eat both – they have different nutrient profiles.
What Is Kale?
Composition: Tough leaves with thick stems, slightly bitter, very nutrient-dense
Best uses: Massaged salads, kale chips, soups (lacinato kale), smoothies
Pros:
- Holds shape in cooking
- Loaded with vitamins K, A, C
- Stays crispy in salads
- Tougher (lasts in fridge)
Cons:
- Bitter on its own
- Needs massaging for salads
- Tough texture some don’t like
What Is Spinach?
Composition: Soft leaves, mild flavor, wilts dramatically when cooked
Best uses: Salads, omelets, smoothies, creamed spinach, soups
Pros:
- Versatile mild flavor
- Soft tender leaves
- Cooks down quickly
Cons:
- Wilts to nothing (need lots)
- Spoils faster
- Higher oxalate content
Can You Substitute One for the Other?
Using Spinach instead of Kale

Using Kale instead of Spinach
Spinach for kale: wilts faster. Need 3x the amount.
My Honest Take
Both excellent greens. Spinach for soft uses (omelets, salads, smoothies). Kale for hearty applications (chips, massaged salads, holding up to cooking). Eat both – they have different nutrient profiles. Both have their place.
