How to Make High-Protein Spinach and Artichoke Chicken Casserole
Step 1: Preheat the Oven
Set your oven to 375°F (190°C). Grease your 9×13-inch casserole dish with a bit of olive oil or cooking spray to prevent sticking.
Step 2: Cook Veggies
In a skillet over medium heat:
1. Add olive oil.
2. Sauté onion for 3–4 minutes until soft.
3. Stir in garlic, spinach, and artichokes. Cook until spinach is wilted. Remove from heat.
Step 3: Make Creamy Base
In a large mixing bowl:
1. Combine Greek yogurt, cream cheese, Parmesan cheese, half of the mozzarella cheese, Italian seasoning, paprika, salt, and pepper.
2. Mix well until smooth.
3. Stir in the sautéed vegetables until fully combined.
Step 4: Add Chicken
Fold shredded chicken into the creamy spinach-artichoke mixture until every piece is coated evenly.
Step 5: Assemble Casserole
Spread the mixture evenly into your prepared casserole dish. Top with the remaining mozzarella cheese for that cheesy goodness.
Step 6: Bake
Bake uncovered in preheated oven for 25–30 minutes or until hot throughout and the cheese on top is golden brown and bubbly.
Step 7: Serve
Allow the casserole to cool slightly before serving. It pairs wonderfully with brown rice or quinoa for an extra boost of nutrients!
