Cajun Shrimp Scampi Ingredients

Ingredients needed for cajun shrimp scampi.
  • Spaghetti: While spaghetti is traditional for this dish, you could use any pasta from spirals to angel hair. 
  • Shrimp: Make sure the shrimp are peeled and deveined before cooking.
  • Seasonings: Garlic powder. Salt, pepper, and cajun seasoning give this dish a great depth of flavor. Mix up your own cajun seasoning with smoked paprika, onion powder, dried oregano, dried thyme, black pepper, and cayenne pepper. 
  • Olive oil and butter: These fats help to cook the shrimp and make the base of the sauce. Any neutral oil will work to cook the shrimp! 
  • Sauce: Butter minced garlic and chopped yellow onion are the aromatic base for the sauce. Chicken broth and lemon juice adds flavor and the richness of the sauce comes from heavy cream. While you could use half and half to lighten up the dish, it won’t have the same luxurious thickness as the heavy cream. 
  • Parmesan cheese: Grated parmesan cheese gets mixed in at the end for even more flavor. 
  • Garnish: Topping the pasta with freshly chopped parsley and a lemon wedge adds another pop of flavor. 

Ingredient Substitutions and Variations:

  • Creamier: Add 1/4 cup of heavy cream to the sauce for a richer, creamier version of this dish.
  • Pasta: You can use any pasta you have on hand, such as fettuccine, penne, or even gluten-free options if needed.
  • Shrimp: For a different protein, swap the shrimp with chicken, scallops, or even sausage for a protein filled dish.
  • Veggies: Add sliced bell peppers to add more flavor to this dish.

Tips Perfect This Recipe

  • Don’t Overcook the Shrimp: Shrimp cook quickly and become rubbery if overcooked. Remove them from the skillet as soon as they turn pink.
  • Pasta: Cook pasta al dente.
  • Use Fresh Garlic: Fresh garlic adds the most flavor, so avoid using jarred garlic.
  • Balance the Heat: Cajun seasoning can vary in spice level, so start with a small amount and adjust to taste. You can always add more, but it’s harder to reduce the heat once it’s too spicy.

What to Serve Cajun Shrimp Scampi

This Cajun Shrimp Scampi is a filling meal on its own, but serving it with a House Salad, Air Fryer Asparagus makes it even more filling. Roasted Garlic Bread or a No Kneed Artisan Bread are great for dipping into the delicious sauce.

Storing and Reheating

Storing: Store leftovers in an airtight container in the refrigerator for up to23 days. 

To reheat: Reheat the scampi in a skillet over medium heat, adding a splash of chicken broth or water to loosen the sauce, if needed. You can also reheat in the microwave in 30 second increments until heated through.

Freezing: I do not recommend freezing any recipe with cream. It’s best not to freeze this recipe.

Alternative Cooking Method

Instant Pot: Using the sauté function, cook the onion and garlic in butter. Add the broth, lemon juice and pasta and cook for 3 minutes on high pressure with a quick release. Add the shrimp and cook for 2-3 minutes until pink, then stir in the heavy cream and parmesan cheese. 

Oven-Baked: For a casserole-style dish, prepare the Cajun shrimp scampi sauce, the shrimp and pasta separately, then mix them together in a baking dish. Sprinkle with Parmesan cheese and breadcrumbs and bake at 375°F for about 10 minutes until golden and bubbly.

Frequently Asked Questions

Can I make this recipe ahead of time?

Cajun Shrimp Scampi with Pasta is best served fresh. However, you can prep the ingredients ahead of time and cook everything just before serving.

How do I adjust the consistency of the sauce?

If the sauce is too thick, thin it with a bit of the reserved pasta water. To thicken a sauce that is too thin, make a cornstarch slurry by dissolving a teaspoon of cornstarch in a tablespoon of water. Whisk the slurry into the sauce a little at a time until you reach your desired consistency.

What’s the best pasta for shrimp scampi?

Linguine or spaghetti is traditional, but any pasta works well. You can also try fettuccine or a short pasta like penne or rigaton.

Can I adjust the spice level?

Absolutely! Start with a small amount of Cajun seasoning and red pepper flakes, then increase to your desired heat level.
