Ingredients You’ll Need

You won’t need to hunt down anything fancy for this comforting classic! Each ingredient in Chicken Spaghetti plays a part—whether it’s adding creaminess, bold seasoning, or a pop of color. Here’s what you’ll need and why it matters:

• Rotisserie chicken, chopped: Saves time and adds deep, roasted flavor right from the deli counter.
• Thin spaghetti (1 lb): Allows all the creamy goodness to coat every strand perfectly without getting lost in the casserole.
• Condensed cream of chicken soup (2 cans): Lends a velvety texture and rich depth; the secret to that decadent sauce.
• Rotel diced tomatoes and green chilies (1 can): Brings tang, mild heat, and juiciness for balance.
• Small onion, chopped: A sweet aromatic base that amplifies every other flavor.
• Garlic cloves, chopped (3-4): Adds robust, classic flavor for real homemade character.
• Lawry’s seasoning salt (1 tsp): For a perfectly rounded savory seasoning.
• Onion powder (1 tsp): Doubles up that savory kick and brings even more depth.
• Garlic powder (1 tsp): Boosts garlic flavor without overpowering.
• Paprika (1 tsp): Provides color and gentle smokiness that ties everything together.
• Dried parsley (1 tsp): Flecks the casserole with green, freshening each bite.
• Cracked black pepper (½ tsp): Adds a little kick that rounds out the flavors.
• Salt (½ tsp): For balance and brightness—you don’t want to skip this!
• Better than Bouillon roasted chicken base (1 tsp): Deepens the chicken flavors for an extra savory note.
• Colby jack cheese, freshly shredded (8 oz): Melts beautifully and makes everything irresistibly gooey.
• Sour cream (½ cup): Gives the sauce a little tang and silkiness.
• Cream cheese (4 oz): Makes the entire casserole creamy and luxurious.

How to Make Chicken Spaghetti

Step 1: Cook the Spaghetti

Start by boiling your thin spaghetti noodles in generously salted water. You want them al dente—firm but not hard—since they’ll soak up more flavor in the oven. Drain and set aside, but don’t rinse. That little bit of starch helps the creamy sauce cling beautifully.

Step 2: Prep the Chicken and Mix the Filling

Chop the rotisserie chicken into bite-sized pieces and toss them into a big mixing bowl. Add the roasted chicken bouillon base, both cans of cream of chicken soup, the entire can of Rotel (juice and all), onion powder, garlic powder, paprika, Lawry’s seasoning salt, dried parsley, chopped onion, chopped garlic, sour cream, cream cheese, salt, pepper, and about 5 ounces of the shredded colby jack. Stir everything together until it’s creamy, colorful, and every bit of chicken is coated in the luscious sauce.

Step 3: Combine with the Spaghetti

Spray a 9×13 baking dish with non-stick spray, and add the cooked spaghetti straight in. Spoon over the creamy chicken mixture. Using tongs or clean hands, gently toss and fold everything together so the pasta is evenly coated and nestled with chicken and bits of veggie.

Step 4: Top with Cheese and Bake

Sprinkle the remaining 3 ounces of colby jack all over the top of the casserole. Slide the dish onto the middle rack of your oven and bake at 375°F for 25 to 30 minutes. The top should be golden, gooey, and slightly bubbly—pure comfort food perfection.

Step 5: Cool and Serve

Let the Chicken Spaghetti sit for at least 5 minutes once it comes out of the oven. This gives the sauce time to settle, making every scoop creamy and perfect. Slice, serve, and prepare for happy forks and a second round of servings!

How to Serve Chicken Spaghetti

Garnishes

Sprinkle your hot Chicken Spaghetti with fresh parsley, a little extra black pepper, or even some red chili flakes if you want more kick. Chopped scallions also add a bright, fresh crunch that’s gorgeous for presentation.

Side Dishes

This dish shines alongside simple sides like a crisp green salad, tangy vinaigrette coleslaw, or buttery garlic bread. Roasted or steamed vegetables—think broccoli or green beans—balance out the richness perfectly.

Creative Ways to Present

Try scooping Chicken Spaghetti into individual ramekins for a dinner party, or serve it in a big, rustic casserole straight to the table for family style. Leftovers even make terrific filling for peppers—just stuff and bake until bubbly!

Make Ahead and Storage

Storing Leftovers

Once cooled, cover any leftover Chicken Spaghetti tightly with foil or transfer slices to airtight containers. Refrigerate for up to four days and rest easy knowing lunch or dinner is sorted—flavors often get even better the next day!

Freezing

This casserole freezes wonderfully. Assemble up to the point just before baking, wrap well, and freeze for up to three months. When you’re ready, thaw in the fridge overnight, then bake as usual. You can also freeze baked leftovers in individual portions for speedy meals.

Reheating

For best results, reheat Chicken Spaghetti in a covered oven-safe dish at 350°F until hot and bubbly, about 20 minutes. Individual servings can be microwaved in short bursts, but stir midway through to keep the cheese extra creamy and prevent hot spots.

FAQs

Can I use another type of pasta?

Absolutely! While thin spaghetti makes for that classic silky texture, you could substitute with linguine or even penne if that’s what you have on hand. Just keep an eye on cooking times—no one likes mushy noodles.

What can I use instead of rotisserie chicken?

Shredded cooked chicken breasts or thighs work perfectly. Poach, roast, or even use leftovers from another meal—the heart of Chicken Spaghetti is all about easy, flavorful shortcuts.

Is Chicken Spaghetti spicy?

The touch of Rotel with green chilies gives gentle warmth but isn’t overtly spicy. If you’re cooking for spice-sensitive folks or kids, use mild Rotel or regular diced tomatoes, and leave chili flakes out of the garnish.

Can I make Chicken Spaghetti ahead?

Yes! You can assemble the casserole up to a day in advance, cover, and refrigerate until baking time. It’s ideal for busy weeknights, meal prep, or taking to friends and family.

What cheese can I substitute for colby jack?

Cheddar or Monterey Jack are great alternatives and melt beautifully. For a sharper, more pronounced cheesy flavor, try half cheddar and half mozzarella or even pepper jack for extra zing!
