Step‑by‑Step Instructions for High-Protein Spinach and Artichoke Chicken Casserole
Step 1: Preheat the Oven
Begin by preheating your oven to 375°F (190°C). This step ensures that the High-Protein Spinach and Artichoke Chicken Casserole bakes evenly, resulting in a beautifully golden top. While the oven warms up, gather your ingredients so you’re ready to whip up this creamy dish.
Step 2: Sauté Aromatics
In a large skillet, heat 2 tablespoons of olive oil over medium heat. Once hot, add 2 minced garlic cloves and 1 diced onion, sautéing them for about 3-4 minutes until fragrant and translucent. This process infuses the base of your casserole with robust flavor, creating a delicious foundation for the rest of the ingredients.
Step 3: Cook the Chicken
Next, add 1 pound of organic chicken breasts or thighs to the skillet. Cook the chicken for approximately 5-7 minutes on each side, until it turns a lovely golden brown. Keep an eye on it; the chicken should be nicely seared but not cooked through yet, as it will finish baking in the oven.
Step 4: Incorporate Spinach and Artichokes
Once the chicken is browned, stir in 2 cups of spinach leaves and 1 can of artichoke hearts (drained and chopped). Mix well and cook for another 3-5 minutes until the spinach wilts down. This addition not only boosts the nutritional value of your High-Protein Spinach and Artichoke Chicken Casserole but also adds a colorful touch.
Step 5: Prepare the Creamy Mixture
In a separate mixing bowl, combine 8 ounces of cream cheese (or Greek yogurt), ½ cup of grated Parmesan cheese, and a teaspoon each of oregano, thyme, and paprika. Blend these ingredients together until smooth, making sure there are no lumps. This creamy mixture will give your casserole its rich flavor and dreamy texture.
Step 6: Combine Everything
Pour the creamy mixture over the chicken and vegetable medley in the skillet. Gently stir until all ingredients are evenly coated, allowing the flavors to meld together. You will notice the vibrant colors of spinach, artichoke, and chicken beautifully combined in this step, enhancing the overall appeal of your High-Protein Spinach and Artichoke Chicken Casserole.
Step 7: Transfer to Baking Dish
Carefully transfer the entire mixture into a greased baking dish, spreading it out evenly. If you’d like, sprinkle a layer of almond flour or coconut flour on top for a crunchier texture. This step is crucial for creating a delicious contrast against the creamy filling once baked.
Step 8: Bake the Casserole
Pop the dish into the preheated oven and bake for 30-40 minutes. You’ll know the casserole is ready when it’s bubbling and the top is golden brown. Make sure the internal temperature of the chicken reaches 165°F (74°C) for safe consumption. Your kitchen will soon fill with an enticing aroma!
Step 9: Serve and Enjoy
Once it’s baked to perfection, remove the casserole from the oven and let it sit for a few minutes before serving. This allows the flavors to settle beautifully. Dish out warm portions of your High-Protein Spinach and Artichoke Chicken Casserole and enjoy this delicious meal with your family or friends!
