How to Make High Protein Chicken Spinach Bake

Ready to create this delicious dish? Here’s a step-by-step guide to help you along the way:

  1. Preheat your oven to 400°F (205°C).
  2. Pat the chicken breasts dry with a paper towel. Season both sides with salt, pepper, and Italian seasoning.
  3. Heat the olive oil in a large oven-safe skillet over medium heat. Once hot, add the chicken and sear for about 2-3 minutes on each side until they are golden brown. Remove them from the skillet and set aside.
  4. In the same skillet, add the diced onion and sauté for about 2-3 minutes until softened. Then, add the minced garlic and sauté for an additional minute until fragrant.
  5. Add the fresh spinach and cook for 2-3 minutes until wilted. Remove the skillet from heat and stir in the Greek yogurt until well combined.
  6. Return the chicken to the skillet, placing it on top of the spinach mixture. Sprinkle the shredded mozzarella cheese on top.
  7. Bake in the oven for 25-30 minutes, or until the chicken reaches an internal temperature of 165°F (74°C) and the cheese is bubbly and golden.
  8. Let it rest for 5-10 minutes before serving, allowing the flavors to meld together nicely.

This dish is versatile, making it easy to customize:

Serving Suggestions

Serve the High Protein Chicken Spinach Bake family-style, allowing everyone to dig in. It pairs wonderfully with rustic Italian bread or a simple green salad on the side. You could even serve it over a bed of zucchini noodles or cauliflower rice for a low-carb twist. For a refreshing beverage, consider pairing it with a crisp white wine or a light iced tea.

Storage, Freezing, and Reheating

To store leftovers, place them in an airtight container in the refrigerator for up to 3 days. When reheating, you can add a splash of water to the pan to keep it moist, especially the cheese layer. If you plan to freeze, portion out the cooled bake in airtight containers or zip bags for up to 2-3 months. Thaw overnight in the fridge and reheat in a 350°F (175°C) oven until heated through.

Frequently Asked Questions

Can I use frozen spinach instead of fresh?

While fresh spinach is recommended for the best texture and flavor, you can use frozen spinach. Be sure to thaw and drain it thoroughly to remove excess moisture before adding it to the dish.

Is it necessary to use Greek yogurt?

Greek yogurt adds creaminess and a protein boost to the dish. However, you can substitute it with sour cream or a non-dairy version if you’re looking for alternatives.

Can I make this ahead of time?

Absolutely! You can prepare the dish up to the point before baking and refrigerate it for a few hours or overnight. Top with cheese and bake before serving.

What is the best way to know that the chicken is fully cooked?

Use a meat thermometer to check the internal temperature, which should read 165°F (74°C). This ensures that the chicken is cooked through and safe to eat.

What can I substitute for mozzarella cheese?

You can use different types of cheese, such as cheddar or gouda, for a different flavor. For a dairy-free option, look for plant-based mozzarella alternatives.
