Ingredients (Serves 6–8)
Protein
- 2 lbs chicken thighs
Pasta
- 1 (16 oz) box spaghetti
Sauce Base
- 2 (10.5 oz) cans cream of chicken with herbs
- 2 cups whole milk
- 1 cup chicken broth
- ½ cup sour cream
Vegetables (Blended)
- 1 green bell pepper
- 1 red bell pepper
- ½ white onion
Cheese
- 1 cup mozzarella cheese, shredded
- 1 cup cheddar cheese, shredded
Seasonings
- 1 teaspoon salt
- 1 teaspoon black pepper
- 1 tablespoon smoked paprika
- 1 tablespoon onion powder
- 1 tablespoon garlic powder
- 1 teaspoon dried oregano
- 4 cloves roasted garlic
Cooking Fat

Step-by-Step Instructions
1. Blend the Vegetables
Direct answer: Puree the peppers and onion until smooth.
- Add bell peppers and onion to a blender.
- Blend into a smooth mixture.
- Set aside.
This creates a flavorful base without chunky texture.
2. Season and Cook the Chicken
- Season chicken thighs with:
- ¼ cup blended vegetable mixture
- Salt, pepper, smoked paprika
- Onion powder, garlic powder, oregano
- Heat grapeseed oil in a large skillet over medium-high heat.
- Sear chicken 4 minutes per side.
- Add chicken broth, cover, and cook until internal temperature reaches 165°F.
- Remove, cool slightly, and shred into bite-sized pieces.
Chicken thighs stay moist and flavorful, even after baking.
3. Cook the Spaghetti
- Boil spaghetti in salted water according to package directions until al dente.
- Drain and set aside.
Do not overcook—the pasta will bake briefly in the oven.
4. Make the Creamy Sauce
In the same skillet:
- Add roasted garlic and 3 tablespoons of blended vegetables.
- Sauté 2–3 minutes to develop flavor.
- Stir in milk and both cans of cream of chicken soup.
- Add sour cream and stir until smooth.
- Mix in ½ cup mozzarella and ½ cup cheddar until melted.
The sauce should be thick, creamy, and well-seasoned.
5. Combine and Assemble
- Add cooked spaghetti to the sauce.
- Fold in shredded chicken.
- Transfer mixture to a greased 9×13-inch baking dish.
- Spread evenly.
6. Add Cheese and Bake
- Top with remaining mozzarella and cheddar.
- Bake at 400°F for 5–10 minutes, just until cheese melts and bubbles.
Avoid overbaking—the dish is already fully cooked.
