Ingredients You’ll Need
- 16 ounces spaghetti noodles: A classic base that holds onto the creamy sauce beautifully. Choose whole wheat or gluten-free if desired.
- 2 tablespoons avocado oil or vegetable oil: This helps sauté the veggies. Avocado oil adds a nutty flavor, while vegetable oil is neutral.
- 1 red bell pepper, sliced thin: Adds sweetness and a pop of color; feel free to substitute with any bell pepper or even zucchini for added nutrition.
- 1 small yellow onion, sliced thin: Brings a savory note to the dish. If you’re not a fan, you can omit it or use shallots for a milder taste.
- 1 (10.5 ounce) can condensed cream of mushroom soup: A creamy backbone to the casserole; look for low-sodium options to control salt levels.
- 1 (10.5 ounce) can condensed cream of chicken soup: Adds thickness and flavor, but you can use more cream of mushroom if you prefer a vegetarian option.
- 1/2 cup chicken broth: Enhances the overall depth of flavor. You can use vegetable broth as an alternative for a lighter option.
- 8 ounces sour cream: Provides creaminess and a slight tang. Greek yogurt can be a good substitute if you’re looking for a healthier alternative.
- 4 ounces softened cream cheese: Makes the sauce super creamy; don’t skip this for the perfect texture!
- 2 ½ cups sharp cheddar cheese, divided: Gives the casserole its cheesy goodness; feel free to mix in some mozzarella or pepper jack for a flavor twist.
- 1 tablespoon ranch seasoning: Adds an irresistible flavor punch. You can make your own seasoning if you’re watching sodium intake.
- Salt and pepper, to taste: Essential for enhancing all the natural flavors in your dish.
- 1 (10 ounce) can Rotel tomatoes with green chilies, lightly drained: For a touch of spice and extra flavor. You can substitute diced tomatoes if you prefer it milder.
- 3 cups chicken, cooked and shredded (rotisserie chicken works great): Easy to prepare ahead of time and adds a rich, protein-packed element to the casserole.
How to Make Chicken Spaghetti Casserole
- Preheat the Oven: Begin by preheating your oven to 350 degrees Fahrenheit. Spray a 9×13-inch baking dish with cooking spray and set it aside.
- Cook the Spaghetti: Prepare the spaghetti noodles according to the package directions until just al dente, which prevents them from becoming mushy once baked. Drain and set aside.
- Sauté the Veggies: In a large, high-walled skillet or Dutch oven, heat the 2 tablespoons of avocado oil over medium heat. Add the thinly sliced red bell pepper and onion, sautéing for 6-7 minutes until they soften. I like to slice them thin so they’ll blend seamlessly into the casserole.
- Prepare the Creamy Sauce: In a blender, combine the cream of mushroom soup, cream of chicken soup, sour cream, chicken broth, cream cheese, ranch seasoning, and salt and pepper. Blend until smooth. This step is optional, but it creates a beautifully creamy sauce. Alternatively, you can whisk these ingredients together in a large bowl.
- Combine Ingredients: Add the shredded chicken and drained Rotel tomatoes to the skillet with your sautéed peppers and onions. Stir well to combine, then pour in the silky sauce. Fold in 1 cup of the cheddar cheese, mixing until everything is creamy and well integrated.
- Mix in the Spaghetti: Add the cooked spaghetti to the skillet and toss with tongs until the noodles are fully coated in the chicken and sauce mixture.
- Bake the Casserole: Pour the spaghetti mixture into your prepared baking dish, spreading it evenly. Sprinkle the remaining 1 ½ cups of cheddar cheese over the top. Bake for 25-30 minutes or until the casserole is heated through and the cheese is bubbling and golden. Let it rest for about 5 minutes before serving.
Storing & Reheating
Store any leftover Chicken Spaghetti Casserole in an airtight container in the refrigerator for up to 3 days. For longer storage, freeze it in a well-sealed container for up to 3 months. When reheating, simply microwave portions for about 2-3 minutes, or warm in the oven at 350 degrees until heated through. Keep in mind that the texture may change slightly once frozen, but a quick stir can refresh the creamy goodness.
Chef’s Helpful Tips
- Ensure the spaghetti is cooked al dente; it will absorb some moisture while baking.
- When shredding chicken, let it cool slightly first; hot chicken can be tricky to handle.
- Consider adding some spinach or another vegetable to boost nutrition and flavor.
- If you notice your sauce is too thick, stir in a little more chicken broth for that perfect consistency.
- This casserole is fantastic for meal prep; make it ahead of time and just pop it in the oven when you’re ready to eat!
This Chicken Spaghetti Casserole is a crowd-pleaser that surely delivers on flavor and comfort. With its creamy texture and delightful taste, it’s a recipe you can rely on again and again!
Recipe FAQs
Can I use whole grain or gluten-free spaghetti?
Absolutely! Whole grain spaghetti is a fantastic way to add some fiber to the dish, while gluten-free spaghetti is readily available and works just as well in this casserole.
What’s the best method for shredding chicken?
Rotisserie chicken is often the easiest option; simply pull it apart with two forks. If you’re cooking your own chicken, boiling is quick and results in tender meat. Just let it cool before shredding to avoid burns!
Can this recipe be made ahead of time?
Yes, you can assemble the casserole a day in advance! Just cover it tightly and keep it in the refrigerator. When you’re ready to bake, add a few extra minutes to the cooking time if it’s cold from the fridge.
How can I make this dish vegetarian?
You can swap out the chicken for a mixture of your favorite vegetables or use chickpeas for a protein boost. Replace the chicken broth with vegetable broth and use vegetable-based soups to keep the flavor robust!
