Homemade Cheesy Chicken Spaghetti

0 First, melt butter with a teaspoon of olive oil in a large skillet over medium-high heat. Once hot, add the diced bell pepper and yellow onion, cooking until they’re soft and fragrant.
1 Next, sprinkle in the all-purpose flour and stir continuously to create a light roux. Gradually whisk in the chicken broth and chicken bouillon powder, stirring until the mixture is smooth and begins to thicken. Season the sauce with garlic powder, salt and black pepper to taste.
3 Stir in the diced tomatoes with green chilies, heavy whipping cream, cooked diced chicken, shredded cheddar and parmesan cheese. Bring to a simmer and allow the cheese to melt.
2 Toss in the cooked spaghetti noodles (cook per package directions) and mix until everything is well combined. Serve & enjoy!
