Let’s Get Cooking: Step-by-Step Instructions
Alright, friend, let’s dive into making this Southern Chicken Spaghetti Casserole. I’m going to walk you through each step, so don’t you worry about a thing!Step 1: Spaghetti Prep
- Preheat your oven to 350°F (175°C).
- Cook the spaghetti according to package directions until al dente. Don’t overcook it, or it will get mushy in the casserole! Drain well and set aside.
Step 2: Sautéing the Aromatics
- While the spaghetti is cooking, melt the butter in a large skillet over medium heat.
- Add the chopped onion (and green bell pepper, if using) to the skillet and cook until softened, about 5-7 minutes. This is where all the flavor starts to build!
Step 3: Creamy, Cheesy Goodness
- In a large bowl (or the same skillet after removing from heat), combine the cream of chicken soup, cream of mushroom soup, diced tomatoes and green chilies, diced pimentos, and softened cream cheese. Make sure the cream cheese is really soft – it will make everything blend much easier!
- Stir in the garlic powder, salt, and pepper. If you’re feeling brave, add a dash of hot sauce for a little zing!
- Mix everything together until smooth and creamy. This is the base of our delicious sauce.
Step 4: Chicken Time
- Add the cooked, shredded chicken to the sauce mixture.
- Stir well to coat the chicken evenly with the creamy sauce.
Step 5: Combining It All
- Add the cooked spaghetti to the chicken and sauce mixture.
- Gently toss everything together until the spaghetti is well coated. Make sure to get all that goodness mixed in!
Step 6: Casserole Assembly
- Pour the spaghetti mixture into a lightly greased 9×13 inch baking dish.
- Sprinkle the remaining cheddar cheese (about 1 cup) evenly over the top of the casserole.
Step 7: Bake to Perfection
- Bake in the preheated oven for 25-30 minutes, or until the casserole is bubbly and the cheese is melted and lightly golden brown.
Step 8: Cool and Serve
- Let the casserole cool for a few minutes before serving. This will help it set up a bit and prevent you from burning your mouth!
Troubleshooting and Tips: My Best Friend Advice
Okay, sometimes things don’t go *exactly* as planned, right? Here’s some friendly advice to help you nail this Southern Chicken Spaghetti Casserole:- Spaghetti Sticking Together? Toss the drained spaghetti with a little bit of olive oil or butter before adding it to the sauce. This will help prevent it from clumping.
- Sauce Too Thick? Add a splash of chicken broth or milk to thin it out to your desired consistency.
- Cheese Not Melting Evenly? Cover the casserole with foil for the first 15 minutes of baking, then remove the foil for the last 10-15 minutes to allow the cheese to brown.
- Make Ahead Tip: You can assemble the casserole ahead of time and store it in the refrigerator for up to 24 hours. Add about 10-15 minutes to the baking time if baking from cold.
- Spice It Up! If you like a little heat, add more diced tomatoes and green chilies, a pinch of red pepper flakes, or a few dashes of your favorite hot sauce.
- Chicken Options: Rotisserie chicken is a fantastic shortcut, but you can also use leftover cooked chicken, canned chicken (drained well), or even cook chicken breasts specifically for this casserole. Just make sure it’s shredded or diced into bite-sized pieces.
