Notes
Serving size 8oz
Shrimp: Always remove the shells completely when serving in a pasta dish unless all shrimp are displayed on top. As a chef this is very important in case a guest would accidentally bite into a shrimp without noticing the shell and possibly choke or at the least have a very unpleasant bite.
Cheese: Parmesan or Pecorino Romano are the 2 best options for this recipe. Pecorino Romano is a sheep's milk cheese and has a slightly tangier flavor.
Poultry: If shrimp isn't your style, consider making chicken tetrazzini or turkey tetrazzini. Great way to use leftover turkey or rotisserie chicken
Garlic and Onion: The secret to getting the best flavor out of this dish is to saute garlic and onion before tossing them in!
Mushrooms: Fresh mushrooms are the way to go. If you are in a crunch and all you have is canned - go for it! However, if you've got time to prepare or run to the store - fresh is best!
Herbs and Spices: Shake things up by adding red pepper flakes or a teaspoon of lemon pepper seasoning to the top of the pasta.
Peas: Looking to add a vegetable and some color to this dish? Consider adding sweet peas!
Lemon Juice: Serve this dish with lemon juice on the side so that your guests can choose how much lemon they want to add to the dish and shrimp before enjoying!
