  • 1 lb peeled and deveined shrimp
  • 8 oz uncooked penne or any tubular pasta
  • 3 tbs butter divided
  • 4 cloves garlic minced
  • 3 tbs fresh chopped parsley divided
  • 1 cup milk
  • 1 tsp chicken bouillon granules OR 1 tsp concentrated chicken stock, like Better Than Bouillon
  • 2 tbs flour
  • 1 cup shredded mozzarella cheese divided
  • 1/4 cup grated Parmesan or Romano cheese
  • 2 small tomatoes seeded and diced
  • 2 tbs Panko bread crumbs
  • salt and pepper to taste


  • Prepare penne per package directions, cooking to al dente stage; drain and set aside.
  • Preheat oven to 350℉.
  • Melt 1 tbs of the butter in a large oven-proof skillet over medium heat. Add the garlic, shrimp and 2 tbs of the parsley. Cook shrimp until it’s pink on each side, about 4 minutes each side. Remove the shrimp to a plate, keep warm.
  • Melt the remaining 2 tbs butter in the same pan. Stir in the flour being careful not to let it lump. Cook until the butter/flour mixture is golden.
  • Add the chicken granules/concentrated stock and stir well.
  • Gradually add the milk, while stirring, until smooth. Add 3/4 cup of the mozzarella and the grated Parmesan or Romano. Stir until cheeses are melted and smooth. Let this simmer for 5 minutes.
  • Add the penne, tomato and shrimp to the pan and toss to combine.
  • Top with the remaining mozzarella and the Panko crumbs.
  • Bake for 5-8 minutes or until cheese is melted.
  • Pop it under the broiler for about 3 minutes to brown the top. Watch this carefully because it can easily burn.
  • Garnish with remaining parsley.
