Step-by-Step Instructions:
1. Sauté the Chicken
Heat olive oil in a large skillet over medium-high heat. Add the cubed chicken and cook until lightly browned on all sides, about 5-7 minutes. You don’t need to cook it through completely.
2. Build the Base
Add chopped onion to the skillet and cook until softened, about 3-5 minutes. Stir in the minced garlic and cook for another minute until fragrant. Pour in the undrained diced tomatoes, chicken broth, oregano, salt, and pepper. Bring the mixture to a simmer.
3. Combine and Layer
Remove the skillet from heat. Stir in the cooked quinoa and half of the fresh basil. Transfer this mixture to an 8×8 inch baking dish.
4. Add the Cheese
Evenly sprinkle the shredded mozzarella cheese over the chicken and quinoa mixture. This creates a delicious cheesy topping for your Healthy Chicken Casserole.
5. Bake to Perfection
Bake in a preheated oven at 375°F (190°C) for 20-25 minutes, or until the cheese is melted and bubbly, and the casserole is heated through. The edges should be slightly golden.
6. Garnish and Serve
Remove the casserole from the oven and let it rest for a few minutes. Sprinkle the remaining fresh basil over the top just before serving. Enjoy your comforting Tomato Basil Chicken and Quinoa Casserole.
