Dice the chicken thighs into bite-sized pieces and place them into a bowl. Then, remove the casings from the Italian sausage.
Boil the pasta per the directions on the box for al dente. Drain and set aside, reserving ¼ cup of the pasta water.
Add the tomato powder, garlic powder, thyme, basil, paprika, and salt to the chicken and toss to coat.
Preheat the olive oil in a large skillet over medium heat. Then, add the diced chicken and cook, stirring occasionally, for 3 to 4 minutes or until a meat thermometer registers 165 degrees. Transfer the chicken to a plate.
Add the sausage to the same pan and cook for 4 to 5 minutes, breaking it apart with a spatula as you go, until the meat begins to brown. Transfer it to the plate with the chicken.
For the Sauce
Lower the heat to medium-low and add the butter to the skillet. Then, cook the bell pepper, minced onion, Italian seasoning, garlic powder, and salt for 1 to 2 minutes until the pepper is translucent.
Add teh flour and stir well. Cook for about a minute, scraping the bottom of the skillet.
Pour in the chicken broth and heavy cream and whisk until a smooth, creamy sauce begins to form.
Reduce the heat to low and add the parmesan cheese. Stir until the cheese is completely melted, then simmer, stirring constantly until the sauce reaches your desired thickness.
Add the cooked chicken and sausage to the sauce and stir well.
If the sauce is too thick, add a bit of reserved pasta water to thin it out. Only add a little at a tim.
Add the cooked pasta and toss well to coat evenly.
Notes
Store any leftovers in the refrigerator in an airtight container for up to 3 days.
Freezing is not recommended because of the creamy sauce.
Spicy Italian sausage creates a dish with a nice kick of heat.
Use plant butter, cheese, and cream for a dairy-free version.
Add fresh vegetables like mushrooms, spinach, kale, or steamed broccoli for more flavor and texture.
Stir your sauce constantly as it cooks to ensure an even texture.
