Here’s what you’ll need to make this delicious pasta dish:
- 1 pound shrimp (cleaned and deveined)
- 8 ounces linguine
- 1 tablespoon oil (olive oil or vegetable oil)
- 1 teaspoon Cajun seasoning (adjust to taste)
- 1 cup half-and-half
- 2 tablespoons butter
- 2 cloves garlic, minced
- Chopped parsley (a few sprigs for garnish)
- 1 Roma tomato, finely diced
- ¼ cup Parmigiano Reggiano cheese
- 1 tablespoon lemon juice (optional)
- Salt and pepper to taste
- Large pot for boiling pasta
- Large skillet or pan
- Tongs or spatula for stirring
- Knife and cutting board
- Measuring cups and spoons
- Whisk
Step 1: Prep the Shrimp
Pat the cleaned shrimp dry with a paper towel, then season with a few pinches of salt, pepper, and ½ teaspoon Cajun seasoning.
Step 2: Cook the Pasta
Cook the linguine according to package instructions until al dente. Drain and set aside.
Step 3: Sauté the Shrimp
- Heat a large pan over medium heat.
- Add the oil and butter to the pan.
- Place the shrimp in a single layer and add the minced garlic.
- Cook for 2 minutes, then flip the shrimp and cook for another 1-2 minutes, or until they turn pink and are fully cooked.
Step 4: Make the Creamy Cajun Sauce
- Pour in the half-and-half and add the Parmigiano Reggiano.
- Bring the mixture to a gentle boil, whisking continuously for about 2 minutes.
- Turn off the heat.
Step 5: Combine Everything
- Add the cooked pasta to the pan.
- Stir in the diced tomato, chopped parsley, and remaining ½ teaspoon Cajun seasoning.
- Squeeze in the lemon juice (optional). Be cautious, as lemon juice can cause dairy to curdle. Adding it with the heat off reduces this risk and enhances the flavor.
- Mix everything well; the sauce will continue to thicken as it cools.
Step 6: Adjust & Serve
- If the sauce becomes too thick, add a splash of half-and-half to restore its creamy texture.
- Serve immediately and enjoy!
- Spice Level: Adjust the Cajun seasoning to your spice preference. If you love heat, add a dash of cayenne pepper.
- Extra Seafood: Swap out shrimp for scallops, or add crab meat for an extra seafood boost.
- Pasta Alternatives: Substitute linguine with fettuccine, penne, or even zucchini noodles for a low-carb option.
- Cheese Swap: Parmigiano Reggiano adds great flavor, but you can also use grated Parmesan or Pecorino Romano.
- Refrigeration: Store leftovers in an airtight container in the fridge for up to 2 days.
- Reheating: Warm over low heat on the stovetop, adding a splash of half-and-half to loosen up the sauce.
- Freezing: Not recommended, as dairy-based sauces can separate upon thawing.
Side Dishes
- Garlic Bread: A crispy slice of garlic bread pairs beautifully with the creamy sauce.
- Green Salad: A light Caesar salad or mixed greens help balance the richness of the dish.
Wine Pairing
- A Chardonnay or Sauvignon Blanc complements the creamy, slightly spicy flavors.
- Prefer red wine? A light Pinot Noir also works surprisingly well.
Can I use frozen shrimp?
Yes! Just make sure to thaw and pat them dry before cooking to prevent excess water from diluting the sauce.
How can I make this dish dairy-free?
Swap half-and-half for coconut milk or a non-dairy cream alternative. Use nutritional yeast instead of cheese for a dairy-free umami boost.
What if I don’t have Cajun seasoning?
You can make a simple Cajun blend using paprika, garlic powder, onion powder, cayenne, oregano, and thyme.
Can I make this dish ahead of time?
While best served fresh, you can prep ingredients in advance and cook everything together when ready to serve.
