How to Make Spicy Southern Cheesy Chicken Spaghetti Casserole
Step 1: Preheat Your Oven
First things first! Preheat your oven to 350°F (175°C). It’s important to get your oven nice and hot so that your casserole bakes 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. This step not only cooks your chicken but also gives it a lovely color that enhances the flavor.
Step 3: Cook the Spaghetti
While your chicken is cooking, boil salted water in another pot. Add the spaghetti and cook until al dente (about 8-10 minutes). Drain it well before setting aside—this will ensure it doesn’t become mushy when mixed into the casserole.
Step 4: Combine Ingredients
In a big bowl, mix together shredded chicken, cooked spaghetti, cream of chicken soup, chopped bell peppers, spices, and half of the cheddar cheese until well combined. This step allows all those delicious flavors to marry together beautifully.
Step 5: Assemble and Bake
Transfer your mixture into the greased casserole dish and sprinkle with the remaining cheddar cheese on top. Bake it for about 25-30 minutes until it’s bubbly and golden brown—a sight that will make everyone eager to dig in!
Step 6: Serve with Love
Let your casserole rest for about five minutes after baking before garnishing with chopped green onions. This short wait allows everything to set nicely so each serving holds together perfectly when you dish it out.
Now you’re ready to enjoy this hearty dish with family or friends! I can’t wait for you all to experience this Spicy Southern Cheesy Chicken Spaghetti Casserole; it’s truly comfort food at its finest!
