Essential Ingredients

Here’s the lineup that makes this dish irresistible—simple staples with big impact:

Spaghetti: The hearty base. Use regular, whole wheat, or gluten-free—whatever you’ve got works.
Chicken: Cooked and shredded for protein. Rotisserie chicken saves time; breasts or thighs cook up fresh.
Cream of Mushroom Soup: The creamy foundation. Swap with cream of chicken or a homemade roux for variety.
Cheddar Cheese: Melts into gooey goodness. Sub with Colby Jack, mozzarella, or a dairy-free option.
Rotel Tomatoes: Adds a mild kick and veggies. Diced tomatoes or salsa can step in if needed.
Bell Pepper: Brings color and crunch. Any color works; skip it or use frozen if you’re short on time.
Onion: Boosts flavor. Yellow is classic; green onions or onion powder (1 tsp) are quick swaps.

These ingredients pack protein, fiber, and vitamins into every bite—comfort food with a healthy twist!

Step-by-Step Instructions

Let’s whip up this pasta perfection in six easy steps:

Cook the Spaghetti: Boil 12 oz spaghetti in salted water per package directions (about 8-10 minutes). Drain and set aside.
Sauté Veggies: In a large skillet, heat 1 tbsp oil over medium heat. Add 1 diced bell pepper and 1 diced onion, cooking 5-7 minutes until soft.
Prep the Chicken: Shred 2 cups cooked chicken (about 2 breasts or 1 small rotisserie chicken). Set aside.
Mix the Sauce: In a large bowl, combine 1 can (10.5 oz) cream of mushroom soup, 1 can (10 oz) Rotel tomatoes (drained), and 1 cup shredded cheddar cheese.
Combine: Add cooked spaghetti, sautéed veggies, and chicken to the bowl. Stir until everything’s coated.
Bake: Transfer to a greased 9×13-inch baking dish, top with 1 more cup cheddar, and bake at 350°F for 20-25 minutes until bubbly.

Your kitchen will smell like cheesy heaven—dinner’s almost ready!

Assembly

Here’s how to bring it all together and make it look as good as it tastes:

Mix It Up: Toss the spaghetti, chicken, veggies, and sauce in the bowl until evenly combined—don’t skimp on the stirring!
Spread Evenly: Pour the mixture into the baking dish, smoothing it out for even cooking.
Cheese It: Sprinkle the remaining cheddar on top—go heavy for that golden, melty crust.
Serve Hot: Scoop generous portions onto plates and garnish with fresh parsley or a dash of paprika for flair.

Serve with a side salad or garlic bread for a meal that screams comfort.

Storage and Make-Ahead Tips

Love leftovers or planning ahead? Here’s how to keep it fresh:

Refrigerator: Store in an airtight container for up to 4 days. Reheat in the oven (350°F for 15-20 minutes) or microwave with a splash of milk.
Freezer: Freeze unbaked in a foil dish for up to 3 months. Bake from frozen at 375°F for 45-60 minutes, covering with foil halfway.
Make-Ahead: Assemble the dish up to 24 hours ahead, refrigerate, and bake when ready—just add 5-10 extra minutes if cold.

Leftover portions taste even better as the flavors meld—perfect for lunch!

Spicy Kick: Use hot Rotel or add diced jalapeños for heat.
Veggie Boost: Mix in spinach, mushrooms, or zucchini with the peppers.
