Step‑by‑Step Instructions for Cheesy Chicken Spaghetti Casserole
Step 1: Preheat and Prepare
Start by preheating your oven to 350°F (175°C) and greasing a large casserole dish with cooking spray or butter. This ensures that your Cheesy Chicken Spaghetti Casserole won't stick, allowing for easy serving later. While the oven heats up, gather your ingredients to streamline the cooking process and make everything feel more efficient.
Step 2: Cook the Chicken
In a large pot, heat a drizzle of olive oil over medium heat. Add the boneless, skinless chicken breasts and cook them for about 6-7 minutes on each side, or until they’re golden brown and cooked through. The chicken should no longer be pink inside. Once done, remove the chicken from the pot and let it rest for a few moments before shredding it into bite-sized pieces.
Step 3: Boil the Spaghetti
In a separate large pot, bring a generous amount of salted water to a rolling boil. Add the spaghetti and cook for 8-10 minutes until it reaches al dente, which means it should be firm to the bite. Once cooked, drain the spaghetti and set it aside while keeping it warm, as this will help it absorb all the flavors in the Cheesy Chicken Spaghetti Casserole.
Step 4: Mix the Ingredients
In a large mixing bowl, combine the shredded chicken, cooked spaghetti, cream of chicken soup, chopped bell peppers, paprika, cayenne pepper, garlic powder, and half of the shredded cheddar cheese. Use a large spoon to mix everything together until well combined, ensuring the flavors meld beautifully for your casserole.
Step 5: Assemble the Casserole
Carefully transfer the chicken and spaghetti mixture into the greased casserole dish, spreading it evenly with a spatula. Top the mixture with the remaining shredded cheddar cheese, creating a deliciously cheesy layer that will melt beautifully in the oven. This step is key to achieving that gooey texture everyone loves!
Step 6: Bake to Perfection
Place the casserole dish in the preheated oven and bake for 25-30 minutes. You’ll know it’s ready when the cheese is bubbly and golden brown, filling your kitchen with mouthwatering aromas. Keep an eye on it in the last few minutes to achieve that perfect golden crust without burning.
Step 7: Let it Rest and Garnish
Once out of the oven, let your Cheesy Chicken Spaghetti Casserole rest for about 5 minutes. This allows the flavors to settle. After resting, sprinkle the sliced green onions on top for a fresh, vibrant finish, giving your comforting dish a delightful touch just before serving.
How to Store and Freeze Cheesy Chicken Spaghetti Casserole
Fridge: Store leftovers in an airtight container for up to 3 days. Make sure to let the casserole cool completely before sealing to avoid condensation.

Cheesy Chicken Spaghetti Casserole Recipe FAQs
What’s the best way to choose ripe bell peppers?
Absolutely! When selecting bell peppers, look for ones that are firm and have a glossy skin. Avoid peppers with dark spots or wrinkles, as these indicate overripeness. A vibrant color—whether green, red, or yellow—also indicates freshness. For the best flavor in your Cheesy Chicken Spaghetti Casserole, select peppers that are bright and heavy for their size.
How should I store leftover casserole?
Very good question! To store your leftover Cheesy Chicken Spaghetti Casserole, let it cool completely, then transfer it to an airtight container. It can be refrigerated for up to 3 days. Ensure that you seal it tightly to prevent it from drying out. It’s a great way to enjoy this comforting dish again!
Can I freeze Cheesy Chicken Spaghetti Casserole? How?
Yes, you can definitely freeze it! First, allow the casserole to cool completely. Then, wrap it tightly in plastic wrap and cover it with aluminum foil for added protection.

When you're ready to enjoy it, thaw it in the fridge overnight, then bake at 350°F (175°C) for about 20-25 minutes until it's heated through.
What if my casserole is too dry?
If your casserole turns out dry, don’t worry! Try adding a bit more cream of chicken soup before reheating. This will bring back the creamy texture. Another tip is to cover the casserole with foil while baking to retain moisture, especially if it’s been sitting in the fridge or freezer. Keeping an eye on the cooking time also helps avoid dryness in the first place!
Is this casserole suitable for kids and those with food allergies?
Certainly! This Cheesy Chicken Spaghetti Casserole can be a hit with kids, especially with its cheesy goodness. However, if anyone in your family has specific allergies, make sure to check the labels on your cream of chicken soup and cheese, as they can sometimes contain allergens. You can also customize it by using gluten-free spaghetti or dairy-free cheese to fit dietary needs!
What’s the best way to reheat the leftovers?
To reheat your leftovers successfully, place the casserole in the oven at 350°F (175°C) for about 20-25 minutes or until heated through.
