Ingredients You’ll Need
These measurements are based on US cup standards for consistency and ease:
- 12 oz spaghetti (uncooked)
- 2 cups cooked shredded chicken (rotisserie chicken works great!)
- 1 (10.5 oz) can cream of chicken soup
- 1 (10.5 oz) can cream of mushroom soup
- 1 cup sour cream
- 2 cups shredded cheddar cheese (divided)
- ½ cup diced green bell pepper
- ½ cup diced onion
- 1 teaspoon garlic powder
- 1 teaspoon paprika
- Salt and black pepper to taste
- ¼ cup chicken broth (optional, for thinning)
Step-by-Step Instructions for Preparation
Below is a detailed breakdown of how to prepare this dish so it’s creamy, cheesy, and baked to perfection:
Step 1: Preheat & Prep
Preheat your oven to 350°F (175°C). Lightly grease a 9×13-inch baking dish with butter or cooking spray. This step ensures the bake doesn’t stick and achieves a golden crust around the edges.
Step 2: Cook the Spaghetti
Bring a large pot of salted water to a boil. Add 12 oz of spaghetti and cook until al dente, following the package directions (usually about 8–10 minutes). Drain and set aside. Tip: Don’t overcook the pasta—it will continue cooking in the oven.
Step 3: Sauté the Veggies
Heat a skillet over medium heat. Add a bit of olive oil or butter, then sauté ½ cup diced green bell pepper and ½ cup diced onion for about 4–5 minutes, or until softened and slightly translucent. This sauté step adds extra depth and sweetness to your bake.
Step 4: Mix the Creamy Sauce
In a large mixing bowl, combine the cream of chicken soup, cream of mushroom soup, sour cream, garlic powder, paprika, and salt and pepper to taste. Mix until the sauce is completely smooth. You can thin the sauce slightly with ¼ cup chicken broth if it seems too thick.
Step 5: Combine Everything
To the sauce bowl, add the cooked and drained spaghetti, shredded chicken, sautéed veggies, and 1½ cups of shredded cheddar cheese. Mix thoroughly until everything is evenly coated.
Step 6: Assemble & Bake
Pour the entire mixture into your prepared 9×13-inch baking dish. Smooth it out evenly with a spatula. Top with the remaining ½ cup cheddar cheese. Bake uncovered for 25–30 minutes, or until the cheese is melted and bubbling around the edges.
