Ingredients

  • 2 cups cooked, shredded chicken breast
  • 1 (14 oz) can artichoke hearts, drained and chopped
  • 2 cups fresh spinach, roughly chopped
  • 1 cup cottage cheese
  • ½ cup plain Greek yogurt
  • ½ cup grated Parmesan cheese
  • 1 cup shredded mozzarella cheese
  • 2 cloves garlic, minced
  • 1 teaspoon onion powder
  • ½ teaspoon salt
  • ½ teaspoon black pepper
  • 1 tablespoon olive oil
  • Optional: crushed red pepper flakes for heat

Directions

Step 1: Preheat the Oven

Preheat your oven to 375°F (190°C). Lightly grease a 9×9-inch baking dish or similar-sized casserole dish with olive oil or nonstick spray.

Step 2: Sauté the Spinach

Heat 1 tablespoon olive oil in a skillet over medium heat. Add the chopped spinach and sauté for 1–2 minutes, just until wilted. Remove from heat and let cool slightly.

Step 3: Combine the Creamy Base

In a large mixing bowl, stir together the cottage cheese, Greek yogurt, Parmesan, garlic, onion powder, salt, and black pepper. Mix until smooth and well combined.

Step 4: Add the Chicken and Vegetables

Fold in the shredded chicken, artichoke hearts, and sautéed spinach. Mix until everything is evenly coated in the creamy mixture.

Step 5: Transfer to Baking Dish

Spread the mixture evenly into your prepared casserole dish. Use a spatula to smooth the top.

Step 6: Add the Mozzarella

Sprinkle the shredded mozzarella evenly over the surface. Add crushed red pepper flakes if you want a spicy kick.

Step 7: Bake

Bake for 25–30 minutes, or until the casserole is hot, bubbly, and the cheese on top is melted and lightly golden.

Step 8: Rest and Serve

Let the casserole rest for 5–10 minutes before slicing. This helps it set and makes serving easier.

Tips for Best Results

  • Use freshly cooked chicken for the juiciest texture, or rotisserie chicken for convenience.
  • Drain artichokes very well to avoid extra liquid in the casserole.
  • Do not skip sautéing the spinach—it prevents excess moisture.
  • Shred your own cheese when possible; it melts better than pre-shredded.
  • Taste and adjust seasoning before baking if your cottage cheese or chicken is already salted.
  • Use a shallow dish if you prefer a slightly crispier top.
  • Let it rest before serving to help flavors meld and the casserole firm up.

Variations & Substitutions

  • Dairy-Free: Use dairy-free yogurt, dairy-free mozzarella, and cashew cream in place of cottage cheese.
  • Keto-Friendly: This recipe is naturally low-carb; increase cheese or add cooked bacon for extra fat.
  • Vegetarian Option: Replace the chicken with cooked white beans or chickpeas.
  • Different Cheeses: Substitute mozzarella with provolone, Monterey Jack, or pepper jack.

Storage & Reheating
