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 vital for ensuring your High-Protein Spinach and Artichoke Chicken Casserole bakes evenly and develops a delicious, bubbly topping. While the oven heats, gather all your ingredients to streamline your cooking process.
Step 2: Prepare the Chicken
Cut your boneless, skinless chicken breast into bite-sized pieces, then season with kosher salt. Allow the chicken to sit at room temperature for about 20 minutes. This resting period enhances the flavor and helps retain moisture during cooking. Meanwhile, you can prepare the artichoke hearts and spinach.
Step 3: Chop the Artichokes
Drain the canned artichoke hearts, squeezing out any excess liquid to prevent a watery casserole later. Finely chop the artichokes and set them aside. This tangy ingredient will add unique flavor and texture to your High-Protein Spinach and Artichoke Chicken Casserole.
Step 4: Thaw the Spinach
Take your frozen chopped spinach out and let it thaw completely. Once thawed, place it in a clean dish towel and squeeze out as much moisture as possible. This ensures your casserole stays creamy rather than watery, providing the perfect texture when baked.
Step 5: Cook the Chicken
In a large skillet over medium heat, add avocado oil or olive oil. Once the oil is hot, add the seasoned chicken pieces, cooking for about 4 to 6 minutes. Stir occasionally until the chicken is mostly cooked through and lightly browned. Remove the skillet from heat and set the chicken aside.
Step 6: Blend the Cheesy Mixture
In a food processor, combine cottage cheese, garlic cloves, kosher salt, black pepper, and onion powder. Blend until the mixture is smooth and creamy. This cheesy blend will be the heart of your casserole, providing richness that complements the other flavors beautifully.
Step 7: Combine Ingredients
In a large baking dish, combine the cooked chicken, thawed spinach, chopped artichokes, and the blended cottage cheese mixture. Mix in ⅔ of both the mozzarella and parmesan cheese, stirring until everything is evenly coated. Spread the mixture out evenly in the baking dish for uniform baking.
Step 8: Bake the Casserole
Cover the baking dish with foil and place it in the preheated oven. Bake for 20 minutes, allowing the flavors to meld together and the casserole to heat through. The steam generated under the foil will help keep the casserole moist during the initial baking.
Step 9: Add the Topping
After 20 minutes, carefully remove the foil and sprinkle the remaining mozzarella and parmesan cheese evenly on top of the casserole. Return it to the oven uncovered and bake for an additional 10 minutes. If you’re aiming for a golden crust, you can broil it for a couple of minutes at the end.
Step 10: Serve and Delight
Once done, take the casserole out of the oven and let it cool for a few minutes. The final result should be bubbly with a golden, cheesy topping. Serve hot and relish this comforting High-Protein Spinach and Artichoke Chicken Casserole, perfect for a nourishing dinner!
