Step‑by‑Step Instructions for Spicy Southern Cheesy Chicken Spaghetti Casserole
Step 1: Preheat and Prepare the Dish
Begin by preheating your oven to 350°F (175°C). While the oven warms up, grease a large casserole dish with cooking spray or butter to ensure easy release after baking. This classic Spicy Southern Cheesy Chicken Spaghetti Casserole will shine in this prepared dish, so take your time to set it up for success.
Step 2: Cook the Chicken
In a large pot over medium heat, add a drizzle of olive oil, then place your boneless, skinless chicken breasts into the pan. Cook them for about 6-7 minutes on each side until they are golden brown and cooked through. This step ensures that the chicken is juicy and flavorful, critical for your casserole’s tasty base.
Step 3: Boil the Spaghetti
While the chicken cooks, bring a pot of salted water to a boil. Add the spaghetti and cook it according to package instructions, usually around 8-10 minutes, until al dente. Drain the pasta in a colander and set it aside, keeping it warm. This will be the comforting base that complements the chicken perfectly in your Spicy Southern Cheesy Chicken Spaghetti Casserole.
Step 4: Combine Ingredients
In a large mixing bowl, shred the cooked chicken with two forks, ensuring it’s well pulled apart. Next, add the cooked spaghetti, cream of chicken soup, chopped bell peppers, paprika, cayenne pepper, garlic powder, and one cup of shredded cheddar cheese. Mix everything together until the ingredients are evenly coated, creating a creamy and vibrant filling for your casserole.
Step 5: Assemble the Casserole
Pour the combined mixture into the greased casserole dish, spreading it evenly across the bottom. Sprinkle the remaining cup of cheddar cheese on top to create a golden crust as it bakes. This step not only enhances the flavor but also adds a satisfying melt that complements the casserole’s creamy texture.
Step 6: Bake the Casserole
Place the casserole in the preheated oven and bake it for 25-30 minutes. Keep an eye on it; the Spicy Southern Cheesy Chicken Spaghetti Casserole is done when it is bubbly and golden brown on top. This will fill your kitchen with delightful aromas, making it hard to resist!
Step 7: Rest and Garnish
Once out of the oven, allow the casserole to rest for about 5 minutes before serving. This will make it easier to scoop out portions. Garnish with freshly sliced green onions for a pop of color and freshness, enhancing both the visual appeal and taste of your delightful casserole.
Make Ahead Options
These Spicy Southern Cheesy Chicken Spaghetti Casserole is a fantastic meal prep solution for busy weeknights! You can prepare the entire casserole up to 24 hours in advance. To do this, simply follow all the steps of the recipe, but instead of baking, cover the dish tightly with plastic wrap or aluminum foil and refrigerate it. When you’re ready to serve, preheat the oven and bake the casserole straight from the fridge for an additional 5-10 minutes to ensure it’s heated through. This way, you can enjoy a delicious, comforting dish that tastes just as wonderful as if it were freshly made, allowing you to savor the joy of home-cooked comfort without the last-minute rush!
