  • 1 pound uncooked rigatoni or penne
  • 1 tablespoon olive oil
  • 1 tablespoon butter
  • 1/2 medium onion chopped
  • 7 ounces cremini or white mushrooms sliced
  • 2 cloves garlic minced
  • 1/4 cup pesto
  • 2 cups heavy/whipping cream
  • 2-3 cups cooked turkey cut up
  • Salt & pepper to taste
  • 2 cups mozzarella cheese shredded
  • Fresh chopped parsley optional, to taste


  • Preheat oven to 375F and move the rack to the middle position.
  • Cook the pasta for 2 minutes less than package directions indicate. Once cooked, drain and add to a greased 9x13 casserole dish.
  • Meanwhile, add the oil and butter to a skillet over medium-high heat. Sauté the onion and mushrooms until the mushrooms have released their water and it's cooked out and everything is nicely browned (about 8 minutes).
  • Stir the garlic in and cook for about 30 seconds.
  • Stir in the pesto and cream and once the sauce starts to bubble, cook for about 2 minutes or until it's slightly thickened (don't let it get too thick as it'll thicken more in the oven). Take the skillet off the heat.
  • Stir in the turkey and some salt & pepper to taste.
  • Transfer the skillet mixture to the casserole dish, add half the cheese, and toss.
  • Top with the rest of the cheese. (Note: if you want it extra cheesy, feel free to add more than the suggested 1 cup on top.)
  • Cover the casserole dish with foil and bake for 20 minutes or until it's warmed through.
  • Take the foil off and broil the top for a few minutes if you want to brown the cheese (optional). Watch that it doesn't burn!
  • Let it sit for a few minutes prior to serving. Sprinkle with chopped parsley if using.


  • Serves 6-8 depending on portion size. Cut the recipe in half and use an 8x8 baking pan if you don't need quite so much.
