How to Make Spicy Southern Cheesy Chicken Spaghetti Casserole
Step 1: Preheat and Prepare
Preheat your oven to 350°F (175°C) and grease a large casserole dish. This step ensures that your casserole won’t stick and will bake evenly.
Step 2: Cook the Chicken
In a large pot over medium heat, cook the chicken for about 6-7 minutes per side until golden brown and cooked through. Cooking the chicken well at this stage keeps it juicy and flavorful throughout the baking process.
Step 3: Boil the Spaghetti
Boil salted water in another pot and cook spaghetti until al dente (about 8-10 minutes). Drain and set aside. Making sure the pasta is slightly undercooked helps it hold its shape when baked in the casserole.
Step 4: Mix It All Together
In a mixing bowl, combine shredded chicken, cooked spaghetti, cream of chicken soup, chopped bell peppers, spices, and half of the cheddar cheese until everything is well blended. This mixture creates layers of flavor that make each bite delightful.
Step 5: Bake to Perfection
Transfer the mixture into your greased casserole dish and top with the remaining cheddar cheese. Bake for 25-30 minutes until it’s bubbly and golden brown on top. Watching it bake is pure joy; you’ll know it’s almost ready when your kitchen starts to smell amazing!
Step 6: Garnish and Serve
Once out of the oven, let your casserole rest for about five minutes before garnishing with sliced green onions. This resting time allows everything to settle, making it easier to serve while adding a fresh touch!
Now that you have all these steps down, get ready to enjoy the heartwarming flavors of this Spicy Southern Cheesy Chicken Spaghetti Casserole!
Pro Tips for Making Spicy Southern Cheesy Chicken Spaghetti Casserole
If you want to elevate your casserole game, these tips will guide you to a deliciously satisfying dish that everyone will rave about.
-
Use Rotisserie Chicken: For a quicker prep time, consider using store-bought rotisserie chicken. It saves cooking time and adds a rich flavor to your casserole.
-
Customize Your Veggies: Feel free to add or substitute vegetables like mushrooms, spinach, or zucchini. This not only boosts the nutritional content but also enhances the taste and texture of the dish.
-
Adjust Spice Levels: If you prefer a milder flavor, reduce the cayenne pepper or omit it entirely. Conversely, if you’re looking for extra heat, add some crushed red pepper flakes on top before baking.
-
Make It Ahead of Time: You can prepare everything a day in advance and store it in the fridge before baking. This allows the flavors to meld together beautifully!

Experiment with Cheese: While sharp cheddar is fantastic, try mixing in Monterey Jack or pepper jack cheese for an extra kick and creaminess.
