How to Make Chicken Spaghetti (Step-by-Step)

Step 1: Cook the Spaghetti

Cook spaghetti in well-salted water until just al dente. Drain and set aside. Avoid overcooking, as the pasta will continue to soften during baking.

Step 2: Prepare the Chicken

If not already cooked, season chicken lightly and cook until done. Shred or dice into bite-sized pieces.

Step 3: Make the Creamy Sauce

In a large skillet:

Melt butter over medium heat
Sauté onion until soft
Add garlic and cook briefly

Stir in cream of chicken soup, cream, and seasonings
Add cream cheese if using and stir until smooth

Step 4: Combine Everything

Add cooked chicken and spaghetti to the sauce. Stir gently until everything is evenly coated.

Step 5: Add Cheese

Fold in half of the shredded cheese, reserving the rest for topping.

Step 6: Bake Until Bubbly

Transfer mixture to a greased baking dish. Top with remaining cheese and bake at 375°F (190°C) for 25–30 minutes, until golden and bubbling.

Ingredients

(Serves 6)

For the Chicken:
• 1.5 lbs boneless chicken thighs (more flavor & moisture than breast)
• 1 tbsp olive oil
• 1 tsp garlic powder
• ½ tsp smoked paprika
• Sea salt & black pepper

For the Sauce:
• 3 tbsp butter (divided)
• 4 garlic cloves, minced
• ¼ cup all-purpose flour (or 2 tbsp almond flour + 1 tbsp coconut flour for low-carb)
• 2 cups low-sodium chicken broth
• 1 cup heavy cream (or full-fat coconut milk for dairy-free)
• 1 (4.5 oz) can chopped green chiles (mild, no salt added)
• 1 tsp dried oregano
• ½ tsp onion powder

Cheese Blend (the star!):
• 1 cup sharp white cheddar, shredded
• ½ cup Monterey Jack, shredded
• ½ cup Parmesan, grated (adds umami depth)

To Finish:
• 12 oz spaghetti (or low-carb shirataki/kelp noodles, rinsed & dry-fried)
• 2 tbsp fresh parsley, chopped
• Optional: 2 strips cooked bacon, crumbled (ties in your love of bacon-cheese combos!)

Instructions

Cook chicken: Season chicken. Sear in olive oil over medium-high 5–6 min per side until golden and cooked through (165°F). Rest 5 min, then dice or shred.
Make sauce: Melt 2 tbsp butter in a large pot. Sauté garlic 30 sec. Whisk in flour; cook 1–2 min (roux). Gradually whisk in broth and cream until smooth. Simmer 5 min to thicken.
Stir in green chiles, oregano, onion powder, and remaining 1 tbsp butter.

Cheese magic: Reduce heat to low. Add cheeses one handful at a time, stirring until melted and velvety. (Too hot = grainy!)
Add cooked spaghetti and chicken; toss to coat. If too thick, add splash of broth.
Stir in parsley (and bacon, if using). Taste—adjust salt only if needed (cheeses & broth add plenty).
