How to Make Spicy Southern Chicken Spaghetti Casserole
Step 1: Prepare Your Oven and Cook Pasta
Start by preheating your oven to 350°F. While the oven heats, cook your spaghetti according to package directions. Drain and set aside. This is a great time to use leftover cooked chicken or pick up a rotisserie chicken from the store to save even more time.
Step 2: Sauté the Onions
In a large nonstick pan over medium heat, melt 1 tablespoon of butter. Add the chopped sweet onion and cook for 4 to 5 minutes until soft and translucent. The sweet onions add a wonderful depth of flavor that balances the spice from the Rotel.
Step 3: Create the Cheese Sauce
Add the seasoned salt, garlic powder, cream of chicken soup, Rotel tomatoes, cubed Velveeta cheese, and milk to the pan with the onions. Stir constantly over medium heat until the cheese is completely melted and the sauce is smooth and creamy. This usually takes about 5 to 7 minutes.
Step 4: Add the Chicken
Fold in your 3 cups of chopped, cooked chicken. Season with black pepper to taste. The chicken should be well coated with the creamy cheese sauce.
Step 5: Combine with Spaghetti
Gently fold in the cooked spaghetti, making sure every strand is coated with that delicious cheese sauce. The pasta will absorb some of the flavors as it bakes.
Step 6: Bake the Casserole
Pour the entire mixture into a greased 9×13-inch casserole dish. Cover tightly with aluminum foil and bake for 20 minutes. This allows all the flavors to meld together beautifully.
Step 7: Add the Cheese Topping
Remove the foil and sprinkle the shredded cheddar cheese evenly over the top. Return to the oven uncovered and bake for an additional 5 minutes, or until the cheese is melted and bubbly.
Pro Tips for the Best Results
Use Rotisserie Chicken: Save time by using store-bought rotisserie chicken. It’s already seasoned and adds even more flavor to your casserole.
Adjust the Spice Level: If you have young kids or prefer less heat, use mild Rotel. For extra spice, go with the original or hot version.
Don’t Overcook the Pasta: Cook your spaghetti just until al dente. It will continue cooking in the oven, and you don’t want mushy pasta.
Make It Ahead: Assemble the entire casserole up to 24 hours in advance. Cover and refrigerate, then add an extra 10 minutes to the baking time.
Freeze for Later: This casserole freezes beautifully. Prepare it in a disposable aluminum pan, cover tightly, and freeze for up to 3 months. Thaw overnight in the refrigerator before baking.
Mix Up the Cheese: While Velveeta creates that signature creamy texture, you can substitute half with cream cheese or add pepper jack for extra flavor.
Serving Suggestions
This hearty casserole is a complete meal on its own, but here are some great sides to round out your dinner:
- Fresh garden salad with ranch dressing
- Garlic bread or Texas toast
- Steamed green beans or broccoli
- Corn on the cob
- Coleslaw
Storage and Reheating
Store leftover casserole in an airtight container in the refrigerator for up to 4 days. Reheat individual portions in the microwave for 1-2 minutes, or reheat the entire dish covered with foil in a 350°F oven for about 20 minutes.
