How to Make High Protein Ground Turkey Casserole

1. Preheat the Oven

Preheat your oven to 375°F (190°C) and grease a 9×9-inch baking dish.

2. Cook the Turkey

In a skillet over medium heat, cook the ground turkey for 6–8 minutes, breaking it apart as it browns until fully cooked.

3. Add Seasoning and Spinach

Stir in garlic powder, salt, and black pepper. Add spinach and cook for 2–3 minutes until wilted and well combined.

4. Make It Creamy

Reduce heat to low and mix in softened cream cheese until fully melted and smooth. Stir until the mixture becomes creamy and well coated.

5. Add Egg and Cheese

Let the mixture cool slightly for about 5 minutes. Stir in the beaten egg and 1/2 cup shredded cheddar cheese until evenly combined.

6. Assemble the Casserole

Transfer the mixture into the prepared baking dish and spread evenly. Top with the remaining cheddar cheese.

7. Bake

Bake uncovered for 20–25 minutes, or until the top is melted, bubbly, and lightly golden.

8. Rest and Serve

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

Tips for Success

• Use room-temperature cream cheese for a smooth, lump-free mixture
• Don’t skip resting time—it helps the casserole hold its shape

• Drain excess liquid from turkey if needed for a firmer texture
• Add vegetables like peppers or zucchini for extra nutrients
