Step-by-Step Instructions
Prepare and Season Chicken
Preheat oven to 400 degrees. Slice chicken breasts in half lengthwise. Pat dry, season with salt, pepper, and Italian seasoning.
Sear the Chicken
Heat olive oil over medium-high heat. Sear chicken for 5-6 minutes per side. Remove, let cool, and dice into bite-sized pieces.
Make the Sauce
Reduce heat to medium-low. Melt butter in the pot, stirring to lift chicken fond. Add onions, cook until soft, then garlic for an additional minute.
- Sprinkle flour over the onions, stir to coat for 2 minutes. Gradually add chicken broth, then milk, whisk until smooth.
- Simmer sauce, add cream cheese, stir until melted. Reduce heat, incorporate cheddar cheese until smooth.
Add Tomatoes and Chicken
Drain juice from tomatoes or use to thin sauce. Add tomatoes and diced chicken to mix, stirring well.
Cook Spaghetti
Boil water, cook spaghetti per package instructions, then drain. Stir into sauce.
Bake the Dish
Transfer mixture to a greased 9×13 casserole dish if not using oven-safe pot. Top with mozzarella cheese, bake for 15 minutes. Broil for 1-2 minutes to brown the top.
Finish and Serve
Remove from oven, garnish with red pepper flakes and parsley. Serve with garlic bread.
Chef Tips for Perfect Results
- Always use room temperature cream cheese for smoother sauce integration.
- Adjust the amount of chilies if you prefer less spice.
- Sealing the pasta with sauce before baking prevents it from drying out.
- Bake the dish uncovered to achieve a crisp cheese top.
- For best results, let the dish set for a few minutes before serving.
Common Mistakes to Avoid
- Overcooking Chicken: Ensure you sear chicken briefly to retain moisture and flavor.
- Not Draining Pasta: Properly drain spaghetti to prevent watery sauce.
- Skipping Fond: Do not skip scraping fond; it enhances the sauce considerably.
- Broiling Too Long: Watch closely during broiling to avoid burning the cheese.
- Cold Cream Cheese: Always use softened cream cheese to avoid lumpy sauce.
