- 1 medium onion, diced: Creates a wonderful base flavor for the sauce.
- 1 tablespoon minced garlic: Fresh garlic enhances the dish’s aroma and flavor.
- 2 teaspoons fresh minced thyme: This adds an earthy note that pairs well with the chicken and tomatoes.
- 1 15-ounce can diced tomatoes: Canned for convenience, they add texture and acidity.
- 1 yellow bell pepper, diced and 1 red bell pepper, diced: For sweetness and color, making the dish visually appealing.
- 3 tablespoons all-purpose flour: Used to thicken the sauce, giving it a creamy consistency.
- 1½ cup chicken broth: Provides a savory base for the sauce.
- 1 12-ounce can evaporated milk: This is key for that creamy texture without being overly heavy.
- ¾ cup grated Parmesan cheese: For depth of flavor and added creaminess.
- 1 cup shredded sharp cheddar cheese: Adds color and richness; feel free to use mild cheddar if preferred.
- ½ cup shredded Monterey Jack cheese: Brings a smooth, melty texture.

How to Make Baked Chicken Spaghetti
- Preheat the Oven: Start by preheating your oven to 350℉ (180℃) to ensure it’s hot and ready for your delicious creation.
- Season the Chicken: Sprinkle salt, pepper, and Creole seasoning (or your choice of spice mix) over 1 pound of boneless chicken breast cut into bite-sized chunks, making sure it’s evenly coated.
- Sauté the Chicken: Heat a Dutch oven or medium pan over medium-high heat and add approximately ¼ tablespoon of neutral oil. Once hot, add the chicken and sauté for about 5-6 minutes on each side until it’s nearly cooked through. Remove the chicken from the pan and set aside.
- Cook the Vegetables: In the same pan, add a little more oil or butter if needed, then toss in 1 medium diced onion, 1 tablespoon minced garlic, 2 teaspoons fresh minced thyme, and more Creole seasoning. Stir for 3-4 minutes until the onions are tender and fragrant.
- Prepare the Spaghetti: Cook 8 ounces of spaghetti according to package instructions in a large pot. Once done, drain and set aside while you make the sauce.
- Add Tomatoes and Peppers: Bring back the sautéed onion mixture and add 1 can (15 ounces) of diced tomatoes and both the diced 1 yellow and 1 red bell pepper. Cook for an additional 2-3 minutes.
- Incorporate Flour: Stir in 3 tablespoons of all-purpose flour and ensure it’s fully mixed in, cooking for about one minute.
- Create the Sauce: Gradually pour in 1 12-ounce can of evaporated milk and 1½ cups of chicken broth, stirring continuously. Bring this mixture to a quick boil, allowing it to thicken for about 2 minutes while stirring.
- Add Cheese: Stir in all but ½ cup of the cheeses (reserving for topping) until melted and combined. Adjust the seasoning with additional salt, pepper, and Creole seasoning to taste.
- Combine with Pasta and Chicken: Gently fold in the cooked chicken and spaghetti to this luscious cheese sauce, ensuring everything is evenly coated.
- Transfer to Baking Dish: Pour the mixture into a lightly greased lasagna pan or 4-quart baking dish. Top with the reserved cheese for that golden crust during baking.
- Bake: Place in the oven and bake at 350℉ (180℃) for 20 minutes or until bubbly and golden around the edges.
Storing & Reheating
Leftovers of your Baked Chicken Spaghetti can be a delightful treat. Store any uneaten portions in an airtight container in the refrigerator for up to 3-4 days. For longer storage, freeze in a freezer-safe dish for up to 3 months. When you’re ready to enjoy it again, simply thaw in the refrigerator overnight and reheat in the oven at 350℉ (180℃) for about 20 minutes, or until heated through. Keep in mind that the texture may alter slightly after freezing, but a sprinkle of cheese before reheating can help refresh its richness.
Chef’s Helpful Tips
- Avoid undercooking the chicken initially; it will finish cooking in the oven and ensures it’s juicy.
- If your sauce seems too thick, add a splash more broth or evaporated milk to reach your desired consistency.
- For extra flavor, consider adding sautéed mushrooms or spinach into the vegetable mix.
- If you like a little crunch, top the dish with seasoned breadcrumbs before baking for a delightful texture contrast.
- Make ahead of time and refrigerate unbaked; bake just before serving!
