High-Protein Spinach & Artichoke Chicken Casserole

This assembly-style recipe is straightforward, focusing on proper moisture control for the best consistency.

Preheat and Prep: Set your oven to 375°F (190°C). Lightly grease a 9×9-inch (or similar size) baking dish.
Sauté the Greens: If using fresh spinach, sauté it in a skillet with a dash of olive oil just until wilted. Pro Tip: If using frozen spinach, ensure you squeeze it in a kitchen towel until it is bone-dry to prevent a watery casserole.
Create the Creamy Base: In a large mixing bowl, whisk together the cottage cheese, Greek yogurt, Parmesan, garlic, onion powder, and pepper. If you prefer a smoother texture, you can pulse the cottage cheese in a blender before mixing.
Fold in Solids: Add the shredded chicken, chopped artichokes, wilted spinach, and 1/2 cup of the mozzarella. Stir until everything is evenly coated in the creamy base.
Layer and Bake: Transfer the mixture to the prepared dish. Smooth the top with a spatula and sprinkle the remaining 1/2 cup of mozzarella over the surface.
The Finish: Bake for 25–30 minutes. The casserole is done when the edges are bubbling and the cheese on top has developed golden-brown spots.

Serving and Storage: Meal Prep Excellence

Serving: This casserole is incredibly filling on its own. To keep it low-carb, serve it alongside roasted cauliflower or a crisp arugula salad. If you aren’t strictly low-carb, it is fantastic scooped onto whole-wheat crackers or served with a side of quinoa.

Storage: This is one of those rare dishes that tastes even better the next day as the flavors meld. Store in an airtight container for up to 4 days in the refrigerator. It reheats beautifully in the microwave or back in the oven at 350°F.

Tips: Optimizing Your Casserole

The “Invisible” Cottage Cheese: If you or your family are sensitive to the “curds” in cottage cheese, simply blend the cottage cheese and Greek yogurt together in a food processor first. You’ll get all the protein benefits with the smooth texture of a heavy cream sauce.
Chicken Shortcuts: Use a store-bought rotisserie chicken to make this recipe even faster. Just remove the skin and shred the breast meat.
Seasoning Check: Artichokes and Parmesan are naturally salty. Taste your mixture before adding extra salt!

Variations: Customizing the Bake

Make this recipe your own with these easy substitutions:

Fiber Boost: Stir in 1 cup of cooked quinoa or lentils for a heartier, grain-bowl style texture.
Vegetable Heavy: Add chopped sautéed mushrooms or roasted red peppers for more volume and micronutrients.
Cheese Swap: For a sharper flavor, swap the mozzarella for Provolone, Fontina, or even a Sharp White Cheddar.

Frequently Asked Questions

Can I freeze this casserole?

Yes! You can freeze it before or after baking. If freezing before, thaw it in the fridge overnight before putting it in the oven. The texture of the Greek yogurt may change slightly upon thawing, but a quick stir will fix it.

Is cottage cheese healthy for baking?

Absolutely. When baked, cottage cheese melts and provides a rich, creamy consistency similar to ricotta but with a significantly higher protein-to-fat ratio.

Can I use chicken thighs?

Yes, shredded chicken thighs work perfectly and will result in an even juicier casserole, though the calorie and fat content will be slightly higher than with breast meat.
