Ingredients

Units Scale
  • 1 lb spaghetti noodles
  • 1 rotisserie chicken, chicken removed and shredded
  • 3 tbsp butter
  • 3 tbsp all-purpose flour
  • 1/3 cup red bell pepper, finely chopped
  • 1/2 yellow onion, diced
  • 1 cup mushrooms, chopped
  • 3 cloves garlic, minced
  • 2 cups chicken broth
  • 2 cups shredded cheddar cheese
  • 1 cup cottage cheese
  • 1/2 cup Castelvetrano olives, sliced
  • 1/2 tsp chili powder
  • 1/2 tsp thyme
  • Salt and pepper to taste


Instructions

  1. Boil a pot of water for pasta noodles. Salt the water and cook the pasta according to package instructions. Strain the noodles and keep them in the pot.
  2. In a skillet over medium heat, melt butter. Add chopped mushrooms, onions, red pepper, and garlic to the pan and sauté until soft. Season with salt and pepper. Sprinkle 3 tbsp of flour into the skillet with the vegetables. Stir to mix into the mixture and let it simmer for 1-2 minutes. The flour will thicken the sauce.
  3. Pour chicken broth into the pan and continue to stir the mixture as it simmers for 3-4 more minutes.
  4. As that is simmering, blend cottage cheese in a high-powered blender until it is smooth and creamy in texture. Pour it into the skillet with the veggie broth mixture and stir until smooth. Let it simmer for a couple more minutes.
  5. Add the veggie sauce to the pot with the noodles. Stir in 1 cup of shredded cheese, chili powder, and chopped olives until the cheese has started to melt, and everything is evenly mixed.
  6. Pour the noodle mixture into a 9×13-inch baking dish and top with 1 cup of cheddar cheese.
  7. Bake in preheated oven for 45-50 minutes. Let the dish sit for 10 minutes before serving. Scoop to serve.
