Equipment

Ingredients

  • ¾ lb. spaghetti or pasta of choice
  • 12 ounces andouille sausage sliced in ¼" coins
  • 3 Tablespoons butter
  • 1 red bell pepper chopped
  • 1.5 cups mushrooms sliced
  • 2 Tablespoons shallot diced
  • 3 cloves garlic minced
  • 1 Tablespoon Cajun seasoning
  • 3 Tablespoons flour
  • 2 cups chicken broth
  • ½ cup heavy cream
  • 1 cup parmesan cheese shredded

Instructions

  • Cook spaghetti according to package directions and drain. Slice andouille sausage into ¼ inch coins and brown in a large skillet on medium heat for 8 minutes, stirring occasionally to ensure all sides get browned. Set aside.
  • Melt butter in a medium-sized saucepot. Sauté bell peppers, mushrooms, and shallots on medium heat for 3-4 minutes until softened. Then add garlic and Cajun seasoning and cook an additional 1 minute.
  • Add flour to the saucepot in 1 tablespoon increments, stirring in between each tablespoon. Once all the flour is incorporated, cook for 1 minute. Then, slowly pour in chicken broth while stirring continuously so the flour doesn't clump.
  • Pour heavy cream into the saucepot and bring to a boil for 1 minute.
  • Lower the heat to a simmer. Stir in freshly grated parmesan cheese and simmer for 10-15 minutes until sauce has slightly reduced and thickened.
  • Add cooked andouille sausage to the sauce and heat through. Toss sauce with spaghetti and serve immediately.

Notes

  • Use fresh parmesan for the best taste and consistency.
  • I don't add salt to this recipe because the store-bought Cajun seasoning I use has enough sodium, but feel free to add salt and pepper to taste.
  • If the sauce isn't thickening, you may need to let it simmer an extra 5-10 minutes. The sauce will thicken upon standing.
