Ingredients You’ll Need

• Boneless, skinless chicken breasts: Use about 1.5 pounds for tender, juicy protein that soaks up the spices perfectly.
• Spaghetti: An 8-ounce box, cooked al dente to hold together well in the casserole.
• Shredded sharp cheddar cheese: 2 cups for that gooey, flavorful cheese goodness that you can’t resist.
• Fresh bell peppers: About 1 cup chopped, for a crunchy, sweet balance to all the spice and cheese.
• Cream of chicken soup: A 10.5-ounce can adds creaminess and helps bind the casserole with its comforting texture.
• Paprika: 1 teaspoon for smoky depth and a faint warmth.
• Cayenne pepper: Just half a teaspoon to bring a spicy kick without overpowering the whole dish.
• Garlic powder: 1 teaspoon to add savory aromatics that elevate the flavor profile.
• Green onions: A quarter cup sliced, for a fresh, mildly sharp contrast as a finishing touch.

How to Make Spicy Southern Cheesy Chicken Spaghetti Casserole

Step 1: Prep the Chicken

Start by cooking the chicken breasts until they’re fully done and tender. You can grill, bake, or poach them—whatever suits your style. Once cooled slightly, shred the chicken into bite-sized pieces. This shredded chicken will absorb all the spices and creamy goodness that come next, providing that hearty base for the casserole.

Step 2: Cook the Spaghetti

Boil your spaghetti just until it’s al dente—firm to the bite but cooked through. Drain it well so the casserole doesn’t get soggy. The spaghetti acts as the perfect vehicle to carry all those tasty layers of cheese, chicken, and spice.

Step 3: Mix the Sauce and Spices

In a large mixing bowl, combine the cream of chicken soup with paprika, cayenne pepper, and garlic powder. Stir in the shredded cheddar cheese, chopped bell peppers, and half of the sliced green onions. The sauce should be rich, creamy, and bursting with flavor that sets the tone for the whole casserole.

Step 4: Combine Everything

Gently fold the shredded chicken and cooked spaghetti into the cheesy, spicy mixture. Make sure everything is evenly coated so every bite delivers the perfect balance of heat, creaminess, and cheesy goodness.

Step 5: Bake to Perfection

Transfer the mixture to a greased casserole dish and spread it out evenly. Bake in a preheated oven at 350°F (175°C) for about 25 to 30 minutes, until the cheese is bubbly and golden brown on top. Let it rest a few minutes before serving so it firms up just right.

How to Serve Spicy Southern Cheesy Chicken Spaghetti Casserole

Garnishes

Finish your casserole off with a generous sprinkle of fresh green onions for a light, crisp contrast. For an added kick, feel free to add some sliced jalapeños or a dash of hot sauce on top. The garnishes not only amp up the flavor but also add a vibrant look that makes this dish all the more inviting.

Side Dishes

Pair this hearty casserole with a simple green salad dressed in a light vinaigrette to balance the richness. Cornbread or garlic bread also makes an excellent accompaniment, soaking up any extra cheesy sauce and complementing the Southern vibes of the dish.

Creative Ways to Present

If you’re entertaining or want to give this classic a twist, serve it in individual ramekins or mini cast iron skillets. Sprinkle extra cheese and broil for a few minutes to get a beautifully crisp top. You can also layer it with sliced tomatoes or avocado for added freshness and color.

Make Ahead and Storage

Storing Leftovers

This casserole keeps beautifully for up to 4 days in the fridge when stored in an airtight container. The flavors actually deepen overnight, making your leftovers taste even better the next day.

Freezing

You can freeze the Spicy Southern Cheesy Chicken Spaghetti Casserole either before or after baking. Wrap it tightly in plastic wrap and foil, or use a freezer-safe container to avoid freezer burn. It’ll keep for up to 3 months without losing its delightful taste and texture.

Reheating

To reheat, thaw if frozen overnight in the fridge and bake at 350°F (175°C) until warmed through and bubbly—usually about 20 minutes. You can also microwave individual portions covered with a damp paper towel to retain moisture and prevent drying out.

FAQs

Can I use a different type of pasta?

Absolutely! While spaghetti is traditional for this casserole, penne, rotini, or even elbow macaroni can work just as well. Just be sure to adjust cooking times slightly since different pasta shapes absorb sauce differently.

How spicy is the Spicy Southern Cheesy Chicken Spaghetti Casserole?

The heat level is moderate with a nice warmth from the cayenne and paprika, but nothing too overpowering. You can always adjust the cayenne pepper up or down to suit your spice tolerance perfectly.

Is there a vegetarian version of this recipe?

Yes! Swap the chicken for sautéed mushrooms or a mix of hearty vegetables like zucchini and eggplant. Use a vegetarian cream of mushroom soup for that creamy base, and you’ll have a delicious vegetarian casserole full of flavor.

Can I make this casserole gluten-free?

Definitely! Use gluten-free spaghetti and substitute the cream of chicken soup with a gluten-free alternative or homemade white sauce. Just double-check all labels for hidden gluten ingredients.

What’s the best way to shred chicken for this casserole?

The easiest way is to cook the chicken breasts until tender, then use two forks to pull them apart. Alternatively, you can pulse cooked chicken briefly in a food processor, but be careful not to overdo it—you want nice, chunky shreds, not chicken paste.
