Ingredients
For the Base:

- 2 cloves garlic, minced
- 1 red bell pepper, diced

For the Creamy Sauce:
- 2 cups shredded Monterey Jack cheese
- 1 cup shredded cheddar cheese
- 2 cups heavy cream or halal-certified alternative
- 1 cup chicken broth
- 1/2 cup sour cream
- 2 tablespoons all-purpose flour
- 1 teaspoon garlic powder
- 1 teaspoon onion powder
- 1/2 teaspoon paprika
- Salt and black pepper to taste
- Fresh parsley for garnish
Step-by-Step Instructions
Step 1: Prepare Your Ingredients
Start by cooking your spaghetti according to package directions until al dente. While the pasta cooks, prepare your chicken and beef bacon. If you’re using raw chicken, cook it thoroughly before shredding or dicing. Cook the beef bacon until crispy, then crumble it for the topping.
Step 2: Create the Flavor Base
In a large skillet or Dutch oven, sauté the chopped onion until translucent (about 5 minutes). Add the minced garlic and cook for another minute until fragrant. Toss in the diced bell pepper and sliced mushrooms, cooking until they soften and develop rich flavor.
Step 3: Make the Creamy Cheese Sauce
Sprinkle the flour over the vegetables and stir to create a roux. Slowly pour in the chicken broth while continuously stirring to prevent lumps. Add the heavy cream, sour cream, and all seasonings. Bring to a gentle simmer, then gradually add the shredded cheeses, stirring until smooth and creamy.
Step 4: Combine Everything
Add the cooked spaghetti and shredded chicken to the sauce, tossing gently to coat everything evenly. If the mixture seems too thick, add a splash of additional broth or cream. Transfer to a greased 9×13 baking dish if you’re planning to bake it.
Step 5: Bake to Perfection
Sprinkle the remaining cheese and crumbled beef bacon over the top. Bake at 375°F (190°C) for 20-25 minutes until bubbly and golden brown. For an extra crispy top, broil for the last 2-3 minutes.
Step 6: Serve and Enjoy
Let the casserole rest for 5 minutes before serving. Garnish with fresh parsley and serve warm. This dish pairs beautifully with a simple green salad or classic homemade coleslaw.

Can I use different pasta shapes?

What sides pair well with this casserole?
This rich dish pairs wonderfully with lighter sides. Try our healthy broccoli salad or a simple mixed greens salad to balance the meal.
Can I make this recipe dairy-free?
Yes! Use dairy-free cheese alternatives and coconut cream instead of dairy products. The flavor will be slightly different but still delicious.
How long do leftovers last?
Leftovers keep well in the refrigerator for 3-4 days. Reheat gently in the oven or microwave, adding a splash of broth if needed.
