Ingredients
  

  • 1 lb ground turkey Choose lean ground turkey for a healthier option in your casserole.
  • 4 oz cream cheese Ensure the cream cheese is softened to blend smoothly into the mixture.
  • 5 oz fresh spinach Spinach will wilt significantly during cooking, so this amount is good.
  • 1 cup cheddar cheese Freshly shredding cheese improves its melting quality and flavor.
  • 1 egg The egg acts as a binder, helping the casserole hold its shape.
  • 0.5 tsp garlic powder Adds a foundational savory flavor to the turkey mixture.
  • 0.25 tsp salt Adjust the amount of salt to your personal taste preference.
  • 0.25 tsp Black pepper Freshly ground black pepper enhances the overall flavor.
  • 0.5 cup diced red bell peppers Adds a touch of sweetness and vibrant color, completely optional.
  • 0.25 cup plain Greek yogurt Incorporates extra creaminess and a protein boost, if desired.

Equipment

  • Skillet
  • 9x9 baking dish

Method
 

  1. Preheat oven to 375°F and grease a 9×9 baking dish.
  2. Cook ground turkey in a skillet over medium heat for 6–8 minutes, breaking it up as it cooks.
  3. Stir in garlic powder, salt, and pepper. Add spinach and cook until wilted, about 2–3 minutes.
  4. Reduce heat to low and stir in softened cream cheese until fully melted and combined.
  5. Let mixture cool for 5 minutes, then stir in beaten egg and ½ cup cheddar cheese.
  6. Transfer mixture to prepared baking dish and top with remaining ½ cup cheddar.
  7. Bake uncovered for 20–25 minutes until bubbly and golden on top.
  8. Let rest for 10 minutes before slicing and serving.

Notes

Feel free to substitute mozzarella for cheddar cheese if preferred. Plain Greek yogurt and diced red bell peppers are optional additions for extra creaminess, flavor, and nutrients. This casserole is excellent for meal prep!
