Step by Step Instructions for Baked Chicken Spaghetti

Let’s dive into the simple steps to create your own Baked Chicken Spaghetti. You’ll love how easily this comes together! Just follow these directions, and soon you’ll have a delicious meal to enjoy.
- Preheat your oven to 350F and move the rack to the top third of the oven. This ensures even baking and a beautifully golden top for your casserole.
- Boil a salted pot of water for the spaghetti and cook it one minute less than the package directions indicate. This is crucial to avoid overcooking the pasta, as it will continue to cook in the oven.
- Meanwhile, prep all the recipe ingredients. Chop the onion, bell pepper, and garlic so they’re ready to go.
- Drain the spaghetti and add it to a greased 9×13 casserole dish. This will be the base of your dish, so make sure it’s well-coated to prevent sticking.
- Add the olive oil and butter to a skillet over medium-high heat. Once it’s hot, add the onions and peppers and sauté for five minutes until they’re soft and fragrant.
- Stir in the garlic and cook for 30 seconds, just until it’s fragrant. Be careful not to burn the garlic!
- Stir in the flour and cook for one minute while continuously stirring. This step is important to remove the raw flour taste.
- Whisk in the chicken broth and cream, ensuring there are no lumps from the flour. This will create a smooth and creamy sauce.
- Stir in the Rotel and chili powder. Let the sauce cook for three to four minutes until it’s slightly thickened, but don’t let it get too thick!
- Turn the burner off and stir in half of the cheddar. This will melt into the sauce, creating a cheesy goodness.
- Stir in the chicken and add a bit of salt and pepper to taste. You want to make sure the flavors are well-balanced.
- Transfer the skillet contents to the baking dish and toss with the spaghetti. Ensure that every piece of pasta gets coated in that delicious sauce.
- Top with the remaining cheddar and cover the casserole dish with foil. This will help retain moisture while baking.
- Bake for 25 minutes. If you like, uncover and broil for a few minutes to get the cheese crispy and golden brown.
Things Worth Knowing
- Don’t overcook the pasta: Cooking the spaghetti one minute less than the package indicates ensures it won’t become mushy in the oven.
- Mix well: Ensure that the chicken, sauce, and spaghetti are thoroughly mixed for an even flavor throughout.
- Customize the heat: If you prefer a milder dish, use Mild Rotel instead of the original.
- Keep an eye on the cheese: Broiling at the end can lead to burning, so watch it closely!
