How to Make the BEST Shrimp Mac and Cheese?

Ingredients Needed for this Recipe…

  • FROZEN or FRESH SHRIMP: Choose large “raw” frozen (or fresh) shrimp. If frozen, choose already deveined, and with tails off (for easy prep). They come in packages of 2 pounds. You will only need about 15 to 17 shrimp. Reserve the rest for another recipe. Just thaw and rinse them well. THEN PREP: On a cutting board, cut each shrimp into 4 pieces. Set them aside.
  • EXTRA VIRGIN OLIVE OIL: Is used to sauté the shrimp.
  • GARLIC CLOVES: You will only need 2 cloves. Fresh garlic is essential for flavoring the shrimp.
  • PASTA: Choose your favorite pasta, cavatappi, shells, or elbows. You will need 1 pound (16 ounces). Cook until al-dente. Do not overcook.
  • CHEESES: For this recipe, I used shredded Gruyere and sharp Cheddar cheese for the cheese sauce. Plus, you will need some grated Parmesan cheese for the topping.
  • FLOUR: You will need only 1/4 cup of all-purpose flour to thicken the sauce. If not flour, you can use cornstarch, and 2 tablespoons to thicken the sauce.
  • DAIRY: You will need 1 pint of Half-and-Half and 1 cup of milk, along with 6 Tbsp. of butter.
  • BREAD CRUMBS: To offer a “restaurant-style” crunchy topping, I used Panko bread crumbs, and it was perfect!
  • SEASONINGS: you will need salt, cayenne pepper, Old Bay seasoning, Dijon mustard, garlic powder, and smoked paprika.

Storing and Reheating…

  1. TO STORE: Store any leftovers in a sealed container and keep them chilled in your refrigerator. It is best for up to 2 days.
  2. TO FREEZE: Always allow the casserole to cool completely before freezing. Then transfer any leftovers to an air-tight container and freeze. You can freeze this mac and cheese for up to 3 weeks. Be sure to thaw it overnight in the refrigerator, then reheat in a 300F oven for 20-30 minutes.
  3. DIRECTIONS TO REHEAT: Keep in mind, you can reheat any leftovers in the microwave, do it in increments (depending on the size of the portions). Also, the cream sauce usually is absorbed after it sits for a period of time, so you may add some half-and-half (about 2 Tbsp. or more if you prefer) over the mac and cheese before reheating it to gain the creamy texture you desire.

TO CLEAN SHRIMP PROPERLY: THAW FIRST. Then run the shrimp under cold running water for about 4 to 5 minutes, this will help remove most of the iodine from the shrimp.  Then allow them to drain in a colander.

QUICK NOTE: This recipe uses cooked shrimp. But you can make it with cooked Lobster. Use tails of lobster and cook them in a skillet, to flavor them as we do with the shrimp. Two or three small tails should be enough. Be sure to chop lobster meat into smaller pieces before combining with the cheese sauce.
