Ingredients You’ll Need

The beauty of this Cheesy Chicken Spaghetti Bake Recipe is in how simple the ingredients are but how perfectly they all come together. You’ll find most of these in your pantry or fridge, and the rotisserie chicken makes it super convenient without skimping on flavor.

• Spaghetti pasta: I like using regular dry spaghetti, but you could try whole wheat or gluten-free if you prefer.
• Cream of chicken soup: This is the creamy base that ties everything together—don’t add water; keep it thick and rich.
• ROTEL (diced tomatoes & green chilies): Adds just the right amount of spice and freshness without overpowering.
• Sour cream: For that extra creamy tang that makes it feel indulgent.
• Low sodium chicken broth: Helps balance the flavors without making it too salty.
• Mexican cheese blend: I divide the cheese to mix some in the sauce and save some to top it off for that perfect golden crust.
• Garlic powder & onion powder: Essential for building savory depth.
• Salt, black pepper & crushed red pepper flakes: Season and add a subtle spicy kick—you can adjust the heat to your liking.
• Rotisserie chicken breast: A quick shortcut that adds tenderness and protein. You can shred it easily with your hands.
• Fresh chopped parsley: For a fresh, herby garnish that brightens the dish before serving.

Variations

One of my favorite things about the Cheesy Chicken Spaghetti Bake Recipe is how easy it is to customize to your taste or dietary needs. Don’t be afraid to get creative here and make it your own!

• Use different cheeses: I’ve swapped in sharp cheddar or mozzarella before, and each gives a slightly different but delicious melty vibe.
• Add veggies: Toss in some sautéed bell peppers or spinach to sneak in some greens without losing the creamy texture.
• Make it spicy: For those who love heat, add extra crushed red pepper flakes or a splash of hot sauce—my husband always asks for this.
• Make it lighter: Swap the sour cream for Greek yogurt and use reduced-fat cheese to cut the richness but keep the creaminess.

How to Make Cheesy Chicken Spaghetti Bake Recipe

Step 1: Prep and Cook the Pasta

Start by preheating your oven to 350°F, and lightly spray a 9×13 baking dish with nonstick spray—it keeps everything from sticking and makes cleanup easier. Then, cook your spaghetti according to the package instructions until it’s just al dente. Drain it well because you don’t want any extra water diluting the creamy sauce later on. Set it aside while you prep the rest.

Step 2: Mix the Creamy Sauce

In the same pot you used for the pasta (no need to dirty another dish—yay for fewer dishes!), stir together the two cans of cream of chicken soup, the entire can of ROTEL with its juices, sour cream, chicken broth, and 1 cup of the shredded Mexican cheese. Add garlic powder, onion powder, salt, pepper, and a pinch of red pepper flakes. Mix everything thoroughly until it’s smooth and creamy.

Step 3: Combine Pasta and Chicken

Fold in the cooked pasta and shredded rotisserie chicken into the sauce. This part I love because everything gets coated so well, making sure every forkful is packed with flavor and cheesy goodness. Don’t rush this—gently toss to avoid breaking the pasta or shredding the chicken unevenly.

Step 4: Bake to Perfection

Pour this creamy mixture into your prepared baking dish and sprinkle the remaining 1 cup of cheese over the top. Cover it tightly with a piece of aluminum foil (nonstick is best here) and bake for about 20 minutes until it’s bubbly and heated through. Then, remove the foil and let it bake for an additional 5-10 minutes so you get that gorgeous golden cheese crust on top. This last step always makes my kitchen smell amazing!

Step 5: Garnish and Serve

Once out of the oven, sprinkle some fresh chopped parsley over the top for a pop of color and freshness. Now it’s ready to serve! Grab your favorite fork and dig in—you’ll love how satisfying this meal feels.

How to Serve Cheesy Chicken Spaghetti Bake Recipe

Garnishes

I always top the bake with freshly chopped parsley—it adds such a lovely pop of green and bright herb flavor that balances the creamy, cheesy richness perfectly. Sometimes I sprinkle a little extra crushed red pepper flakes if everyone’s feeling adventurous!

Side Dishes

This bake pairs beautifully with a crisp green salad or steamed veggies like broccoli or green beans to cut through the richness. I’ve also served it alongside garlic bread for a totally indulgent meal that everyone raves about.

Creative Ways to Present

For family gatherings or potlucks, I scoop this bake into individual ramekins and sprinkle a little extra cheese and parsley before broiling for a couple of minutes—super cute and everyone loves their own cheesy portion. You could also garnish with sliced avocado or a dollop of sour cream for a creamy finish with a twist.

Make Ahead and Storage

Storing Leftovers

Leftovers from this Cheesy Chicken Spaghetti Bake store wonderfully in an airtight container in the fridge for up to 3 days. I always let it cool completely before sealing the container to keep things fresh. Reheating is so easy and still tastes fantastic.

Freezing

I’ve frozen this bake a couple of times, and it works great! Just make sure to cool it completely, then cover tightly with foil and pop it in the freezer for up to 3 months. When you’re ready, thaw overnight in the fridge before reheating for best results.

Reheating

To reheat, I like warming it in the oven at 350°F covered with foil to retain moisture, usually for about 15-20 minutes until heated through. If you’re in a hurry, microwave it covered for a few minutes, stirring halfway. Adding a splash of broth or water before reheating helps keep it creamy.
