How to Make It
Step 1: Preheat the Oven
Preheat your oven to 350°F (175°C). This ensures your casserole will bake evenly and come out bubbly and golden brown.
Step 2: Cook the Chicken
Grease a large casserole dish. In a large pot over medium heat, cook the chicken for about 6-7 minutes per side until golden and cooked through. The smell of sizzling chicken will fill your kitchen—trust me, it’s a delightful aroma!
Step 3: Boil the Spaghetti
While the chicken cools, boil salted water in a separate pot and cook your spaghetti until al dente (about 8-10 minutes). Drain and set aside. Don’t forget to save a cup of pasta water for later if you want to adjust the sauce consistency!
Step 4: Combine Ingredients in a Bowl
In a big mixing bowl, shred the cooked chicken and mix it together with the cooked spaghetti, cream of chicken soup, chopped bell peppers, spices, and half of the shredded cheddar cheese. The colors are vibrant, and it’s hard to resist tasting at this stage!
Step 5: Transfer to Casserole Dish
Pour the mixture into your greased casserole dish and spread it out evenly. Top with the remaining cheese, imagining the glorious golden layer it’ll create as it bakes.
Step 6: Bake
Bake for 25-30 minutes until everything is bubbly and the cheese is meltingly golden. That moment is pure bliss—wait until you see it!
Step 7: Rest & Garnish
Let it rest for about 5 minutes before garnishing with the chopped green onions and serving. The aromas will have everyone rushing to the table!
Pro Tips for Success
- Prep Ahead: Cook and shred your chicken in advance to make this meal a breeze on a busy weeknight.
- Don’t Overcook the Pasta: Since it’ll continue cooking in the oven, underbake your spaghetti just a bit.
- Use Rotisserie Chicken: For an even quicker meal, pick up a rotisserie chicken from your local grocery store.
- Experiment with Cheese: Mix it up with pepper jack or mozzarella for different flavors!
Flavor Variations
Feel free to swap the peppers for any veggies you have on hand or even throw in some cooked broccoli or frozen peas. Want more heat? Add diced jalapeños or a dash of hot sauce to your casserole mix.
Serving Suggestions
Pair your Spicy Southern Cheesy Chicken Spaghetti Casserole with a fresh garden salad or some buttery garlic bread for a complete meal. A chilled glass of lemonade or iced tea beautifully complements the dish’s richness.
Make-Ahead & Storage
To prep ahead, you can assemble the casserole a day in advance, cover it well, and pop it in the fridge. It’ll keep for about 3 days if stored in an airtight container, making it a great option for meal prepping!
Leftovers
Reinvent your leftovers with a delicious wrap! Use a tortilla and fill it with the casserole mixture for a quick lunch, or toss it into an omelet for breakfast.
Freezing
Yes, this casserole can be frozen! Prepare the dish as directed but don’t bake it. Instead, tightly wrap it in plastic and foil, and it’ll keep well for up to 2 months. Thaw overnight in the fridge before baking.
Reheating
The best way to enjoy your leftovers is to reheat in the oven for about 15-20 minutes at 350°F until warm. If you’re in a hurry, a quick microwave session in a microwave-safe container works too—just keep an eye on it!
FAQs
Can I use another type of pasta?
Absolutely! Feel free to swap out spaghetti for penne, fusilli, or whatever pasta you love.
Is this casserole spicy?
It has a slight kick from the cayenne, but it’s not overwhelming. You can adjust the spice level to your liking!
Can I make this vegetarian?
Yes! Replace the chicken with cooked lentils or beans and skip the cream of chicken soup for a rich veggie alternative.
How long does it take to cook from frozen?
From frozen, bake at 350°F for about 45-60 minutes, covered with foil to prevent browning. Make sure it’s heated through before serving.
