Ingredients You’ll Need

There’s something magical about using just the right ingredients—each one in this Chicken Spaghetti Recipe has its own delicious job to do, whether it’s adding a creamy base, a bright pop of color, a hearty bite, or an irresistible cheesy finish. Here’s what you’ll gather:

Spaghetti noodles (12 oz): The classic base—holds up perfectly to the creamy sauce and bakes without getting mushy.
Olive oil (2 tablespoons): Gives the veggies a silky sautéed texture and richer flavor.
Small onion, diced: Adds subtle sweetness and depth to the dish.
Green bell pepper, diced: Brings a splash of color and a gentle crunch.
Garlic cloves, minced: Lifts every bite with aromatic warmth.
Cooked, shredded chicken (2 cups): Rotisserie chicken works wonders for ease and tender texture.
Cream of mushroom soup (10.5 oz can): Adds savory creaminess and a hint of earthiness.
Cream of chicken soup (10.5 oz can): Deepens the richness and helps bind the casserole together.
Diced tomatoes with green chiles (10 oz can, undrained): A splash of tang, a pop of mild heat, and lots of flavor.
Chicken broth (1/2 cup): Keeps the noodles juicy and the sauce smooth—avoid dryness!
Shredded cheddar cheese (2 cups, divided): Melts beautifully for stretch and flavor; use half inside, half on top for golden perfection.
Seasoned salt (1 teaspoon): Boosts all the flavors—don’t skip it.
Black pepper (1/2 teaspoon): Simple seasoning for a savory kick.
Paprika (1/2 teaspoon): Adds color and a whisper of smoky flavor.

How to Make Chicken Spaghetti Recipe

Step 1: Prep Your Oven and Pasta

Preheat your oven to 350°F (175°C) and get your baking dish ready with a light grease. Bring a pot of salted water to a boil and cook the spaghetti just until al dente—the magic word for pasta that holds some bite, perfect for baking later. Drain well and set aside; you don’t want excess water thinning out your creamy sauce.

Step 2: Sauté the Veggies

Heat the olive oil in a large skillet over medium heat, then toss in your diced onion and green bell pepper. Sauté for about 5 minutes until softened and fragrant, stirring occasionally so nothing sticks. Add the minced garlic and let it cook for just a minute more; your kitchen will smell amazing by now!

Step 3: Mix It All Together

In a large bowl, combine your sautéed veggies, shredded chicken, both cans of soup, undrained tomatoes with green chiles, chicken broth, 1.5 cups of cheddar, seasoned salt, black pepper, and paprika. Don’t forget the cooked spaghetti! Give everything a thorough mix—there should be creamy sauce clinging to every strand.

Step 4: Assemble and Cheese It Up

Spread your mixture into your greased 9×13-inch baking dish. Sprinkle that remaining cheddar cheese evenly over the top—it’s what will form that bubbly, golden crown in the oven.

Step 5: Bake Until Bubbly

Slide your assembled Chicken Spaghetti Recipe casserole into the oven. Bake for 25 to 30 minutes, until the cheese is fully melted, lightly golden, and the sauce is nice and bubbly around the edges. The aroma will let you know it’s ready before the timer even beeps!

How to Serve Chicken Spaghetti Recipe

Garnishes

Try a shower of chopped fresh parsley or sliced green onions over the piping-hot casserole for a fresh, colorful finish. Cracked black pepper or even a pinch of crushed red pepper flakes can give each serving an extra pop if you like a touch of heat.

Side Dishes

This dish is hearty on its own, but it pairs wonderfully with simple sides like a crisp green salad, air fryer broccoli, or buttery garlic bread to scoop up every bit of that delicious sauce. For something lighter, go with roasted veggies or a fresh tomato-cucumber salad.

Creative Ways to Present

For entertaining, bake your Chicken Spaghetti Recipe in individual ramekins, or swirl servings onto plates with extra cheese broiled on top for dramatic flair. You can even scoop the hot casserole into hollowed-out bell peppers or bread bowls for a playful spin at family gatherings!

Make Ahead and Storage

Storing Leftovers

Store leftover Chicken Spaghetti Recipe in an airtight container in the fridge for up to 4 days. The flavors deepen and the texture stays creamy, making leftovers just as comforting the next day!

Freezing

This casserole is freezer-friendly! Assemble but don’t bake, cover tightly, and freeze for up to 2 months. When you’re ready, thaw overnight in the refrigerator and bake as directed; add a few extra minutes if baking from chilled.

Reheating

Reheat individual servings in the microwave until piping hot, or cover and warm larger portions in a 325°F oven. If things look a little dry, add a splash of chicken broth before reheating to revive that delicious creaminess.

FAQs

Can I use a different type Main Course

Absolutely! While classic spaghetti is traditional, other long pastas like linguine or fettuccine work well. Short shapes like penne or rotini will also soak up the sauce nicely if you want a twist.

Can I add extra vegetables?

Definitely—mushrooms, peas, or chopped spinach are easy to mix in. Just sauté your veggies until tender before combining to ensure everything bakes evenly and stays flavorful.

What if I don’t have Rotel tomatoes?

You can substitute with regular diced tomatoes and a small can of chopped green chiles, or just use plain diced tomatoes for a milder version of the Chicken Spaghetti Recipe.

Is there a gluten-free option?

Yes! Use gluten-free spaghetti and check that your soups are certified gluten-free. The results are just as creamy, cheesy, and delicious.

How can I make it spicier?

To turn up the heat, try pepper jack cheese instead of cheddar, or add a dash of hot sauce to the mix. Finishing with chopped pickled jalapeños is great for a spicy kick, too!
