Spinach Artichoke: Dip or Casserole?
If you love warm, cheesy spinach artichoke dip, you’ll enjoy this casserole version. Instead of serving it as an appetizer, this recipe adds extra vegetables and quinoa to make a satisfying, nutritious main course that still delivers that familiar creamy flavor.
Everything You Need
This casserole is easy because most ingredients go straight into a greased baking dish, you pour a creamy sauce over them, and bake. Key ingredients:
- Quinoa
- White onion
- Fresh spinach
- Russet potato
- Artichoke hearts
- Cream cheese
- Vegetable broth
- Milk
- Garlic powder or fresh garlic
- Salt and pepper
- Mozzarella
- Parmesan

It’s All About the Cheese Sauce
The rich, creamy cheese sauce is what makes this quinoa casserole indulgent yet homey. Instead of relying on cornstarch or a heavy roux alone, this recipe combines a simple roux with cream cheese and shredded cheese. The potato adds natural starch, so as the casserole bakes the sauce thickens into a velvety coating.
Prepare a quick roux, incorporate milk, then add cream cheese and yogurt for tang and body. Once the sauce is poured over the casserole, baking brings everything together into a luscious finish.
Pro tip
Stir the casserole halfway through baking. If you prefer a saucier result, add a splash more broth when you stir.

Tips & Tricks for the Perfect Quinoa Casserole
Spray the Dish
Coat the casserole dish with nonstick spray so cheese and quinoa don’t stick and cleanup stays easy.
Liquid to Quinoa Ratio
Quinoa typically needs about 3.5 parts liquid to 1 part quinoa. This recipe uses 1.5 cups quinoa and roughly 3 cups of liquid (broth and milk), but you can add more liquid if you like a looser casserole.
Cover the Casserole
Cover the dish with foil for the first part of baking to trap steam and help the quinoa and potatoes cook through. Remove the cover for the final minutes to brown the top.
Let it Rest
After removing the casserole from the oven, let it sit at least 10 minutes. Resting allows excess liquid to settle and the casserole to set, so don’t worry if it looks slightly runny right out of the oven.
