Step‑by‑Step Instructions for High-Protein Spinach and Artichoke Chicken Casserole
Step 1: Preheat the Oven
Begin by preheating your oven to 350°F (175°C). This step is crucial as it ensures that your High-Protein Spinach and Artichoke Chicken Casserole will cook evenly and thoroughly. While the oven is warming, gather your ingredients to streamline the cooking process.
Step 2: Sauté the Garlic
In a skillet, heat a tablespoon of olive oil over medium heat. Once the oil glistens, add minced garlic to the pan, sautéing for about 1-2 minutes or until fragrant. This step builds a savory foundation for the casserole, filling your kitchen with a delightful aroma as you prepare the vibrant spinach.
Step 3: Cook the Spinach
Add the chopped spinach to the skillet with the sautéed garlic, stirring continuously. Cook until the spinach wilts, which should take around 3-5 minutes. Ensure the spinach is well-drained if using frozen to avoid excess moisture in your High-Protein Spinach and Artichoke Chicken Casserole.
Step 4: Combine Ingredients
In a large mixing bowl, combine the shredded chicken, wilted spinach, artichoke hearts, Greek yogurt, mozzarella cheese, and Parmesan cheese. Season with oregano, onion powder, salt, and black pepper. Stir well for about 2 minutes until all ingredients are evenly mixed, creating a creamy and hearty mixture.
Step 5: Prepare the Baking Dish
Lightly grease a baking dish with a little olive oil or cooking spray to prevent sticking. Carefully pour the chicken and spinach mixture into the baking dish, spreading it evenly with a spatula. This ensures that every bite of your casserole is packed with flavor and goodness.
Step 6: Add Breadcrumb Topping
If you desire extra crunch, sprinkle breadcrumbs evenly over the top of the casserole. This optional step enhances the texture, providing a delicious contrast to the creamy filling. Feel free to customize the amount based on your preference, or skip it for a gluten-free option!
Step 7: Bake the Casserole
Place the baking dish in the preheated oven and bake for 30-35 minutes. Look for a golden-brown crust and bubbly edges as visual indicators that your High-Protein Spinach and Artichoke Chicken Casserole is ready. The cheese should be melted and the casserole should be hot all the way through.
Step 8: Cool and Serve
Once baked, remove the casserole from the oven and let it cool for about 5-10 minutes. This resting period allows the flavors to meld beautifully. Serve warm, and enjoy the comforting goodness of this nutritious dish bursting with flavor and protein!
