Ingredients You’ll Need
The beauty of this High-Protein Spinach and Artichoke Chicken Casserole Recipe is in its straightforward and wholesome ingredients. Each one plays a crucial role—from the creamy textures to the vibrant flavors and the protein that keeps you energized.
- 2 lbs boneless, skinless chicken breasts, cooked and shredded: This lean protein serves as the casserole’s hearty base, making it ultra filling.
- 1 (14 oz) can artichoke hearts, drained and chopped: These add a subtle tang and a lovely texture contrast that brightens the dish.
- 1 (10 oz) package frozen spinach, thawed and drained: Spinach brings freshness, color, and a boost of vitamins to your bake.
- 1 cup plain Greek yogurt: Creamy and tangy, Greek yogurt adds moisture and a bit of protein with fewer calories than cream.
- 1 cup cottage cheese: This lends a smooth, rich texture that melts beautifully inside the casserole.
- 1 cup shredded mozzarella cheese: Mozzarella provides gooey, stretchy cheese pull that makes every serving irresistible.
- ½ cup grated Parmesan cheese: Parmesan rounds out the cheese flavor with sharp, nutty notes and adds a golden crust when baked.
- 2 cloves garlic, minced: Garlic infuses the casserole with savory warmth and depth.
- 1 teaspoon onion powder: This enhances the overall flavor without overwhelming the other ingredients.
- Salt and pepper to taste: The essential seasoning that balances and elevates every bite.
How to Make High-Protein Spinach and Artichoke Chicken Casserole Recipe
Step 1: Preheat Your Oven
Start by warming your oven to 375°F (190°C). This temperature is just right to bake the casserole evenly, melting the cheeses while keeping the chicken moist and tender.
Step 2: Combine the Ingredients
In a large bowl, mix the shredded chicken with the chopped artichoke hearts and the thawed, drained spinach. Then add the Greek yogurt, cottage cheese, minced garlic, onion powder, salt, and pepper. Stir everything together until you have a well-blended, creamy mixture. It’s the comforting base of this High-Protein Spinach and Artichoke Chicken Casserole Recipe.
Step 3: Prepare the Baking Dish
Grease a 9×13-inch baking dish lightly to prevent sticking and ensure easy serving later. This simple step makes cleanup a breeze too.
Step 4: Assemble the Casserole
Spread your chicken and vegetable mixture evenly in the baking dish. Top it off with shredded mozzarella and sprinkle the grated Parmesan cheese all over. This cheese layer will brown to a gorgeous golden crust as it bakes, adding both flavor and visual appeal.
Step 5: Bake Until Bubbly
Place your casserole in the preheated oven and bake for 25–30 minutes. You’ll know it’s ready when the cheese is melted, bubbly, and has a delightful golden hue. The aroma filling your kitchen at this point will be utterly inviting.
Step 6: Cool and Serve
Allow the casserole to cool for a few minutes before serving. This rest time lets flavors settle and makes it easier to slice and plate. For an extra touch, sprinkle fresh parsley on top for a pop of color and freshness.
How to Serve High-Protein Spinach and Artichoke Chicken Casserole Recipe

Garnishes
A sprinkle of chopped fresh parsley or chives adds a lovely burst of green and subtle herbal brightness to cut through the creamy, cheesy richness. A few cracked black pepper flakes can also add a nice little kick.
Side Dishes
This casserole is hearty enough to be the star of the meal, but pairing it with a light side like a crisp mixed green salad or roasted vegetables balances out the plate beautifully. For a little extra carb comfort, garlic bread or quinoa works wonderfully.
Creative Ways to Present
If you’re serving guests or want to elevate your everyday meal, try spooning the casserole into individual ramekins for personalized servings. Garnish each with a colorful sliced cherry tomato or a drizzle of balsamic glaze to make it look restaurant-worthy.
Make Ahead and Storage
Storing Leftovers
Leftover High-Protein Spinach and Artichoke Chicken Casserole Recipe keeps well in an airtight container in the refrigerator for up to 3–4 days. It tastes even better as the flavors meld overnight, making it perfect for quick lunches or dinners on busy days.
Freezing
You can freeze this casserole either before or after baking. Just cover it tightly with plastic wrap and aluminum foil, and store in the freezer for up to 3 months. When ready to enjoy, thaw in the fridge overnight before reheating.
Reheating
To reheat, warm individual portions in the microwave or place the whole casserole in a 350°F (175°C) oven, covered with foil, until heated through and bubbly, about 20–25 minutes. If you want to crisp up the top again, remove the foil in the last 5 minutes of baking.
FAQs
Can I use fresh spinach instead of frozen?
Absolutely! If using fresh spinach, sauté it lightly first to remove excess moisture, then chop and use about 10 cups to replace the frozen package. This helps avoid a watery casserole.
Is this recipe suitable for meal prepping?
Definitely! This High-Protein Spinach and Artichoke Chicken Casserole Recipe reheats beautifully and stays moist, making it ideal for preparing several meals in advance.
Can I substitute the chicken with turkey or another protein?
Yes, ground turkey or shredded turkey breast works well too. Just be sure the meat is cooked and shredded before mixing to maintain the casserole’s texture.
Could I make this recipe dairy-free?
While this casserole relies on cheese and dairy for its creamy texture, you could experiment with dairy-free yogurt, cheese alternatives, and omit cottage cheese. The flavor will be different but still tasty.
What can I use instead of Greek yogurt?
If Greek yogurt isn’t available, sour cream can be a good substitute, providing a similar tang and creaminess. Just keep in mind the nutritional content will vary slightly.
