Ingredients you’ll need
- 8 oz thin linguini pasta
- 1 small onion, diced (about 1 cup)
- 2 cups heavy cream
- 1½ cups reserved pasta water
- 1 tbsp paprika
- ¾ cup grated Parmesan cheese (or 6 oz cream cheese)
- 1 tsp salt
- 1 tsp black pepper
- 2 tbsp low-salt Cajun seasoning
- 1 tsp cayenne pepper (optional, for extra heat)
- 1 tbsp olive oil for the sauce

Shrimp seasoning
- 2 lbs shrimp, peeled and deveined
- 1 tbsp olive oil for searing
- ¾ tsp garlic powder
- 1 tsp onion powder
- 1½ tsp paprika
- 2 tbsp low-salt Cajun seasoning
Note: For convenience, use peeled and deveined shrimp. Leave the tails on or off based on preference. If using frozen shrimp, thaw in a colander under cold running water or overnight in the fridge.

Instructions
- Cook the pasta: Bring a large pot of salted water to a boil and cook the linguini until al dente, following package directions. Reserve about 1½ cups of the pasta cooking water before draining.
- Season the shrimp: In a bowl, toss the shrimp with paprika, onion powder, garlic powder, and the low-salt Cajun seasoning so they are evenly coated.
- Sear the shrimp: Heat 1 tbsp olive oil in a skillet over medium-high heat. Sear the shrimp 5–7 minutes, turning once, until they are mostly opaque and just shy of cooked through. Remove the shrimp and set aside.
- Sauté the onion: In the same skillet, add 1 tbsp olive oil if needed and sauté the diced onion until softened and lightly caramelized.
- Build the sauce: Add the paprika, cayenne (if using), Cajun seasoning, reserved pasta water, and heavy cream to the skillet. Lower the heat and simmer gently for 2–3 minutes to combine flavors.
- Add cheese and finish: Stir in the grated Parmesan (or cream cheese), stirring until melted and incorporated. Simmer another 1–2 minutes to thicken slightly.
- Toss with pasta: Add the drained pasta to the skillet and toss thoroughly so each strand is coated in the creamy Cajun sauce.
- Return the shrimp: Add the seared shrimp back into the skillet, mix gently, cover, and simmer for 3–4 minutes on low heat until the shrimp are fully cooked and the sauce has thickened to your liking.
- Serve: Garnish with chopped parsley or red pepper flakes, if desired, and serve immediately.

Recipe notes and tips
- Cook the pasta al dente so it keeps a pleasant bite after finishing in the sauce.
- Stir the pasta after adding it to boiling water to prevent sticking.
- Reserve pasta water before draining—its starch helps bind and thicken the sauce for the best texture.
- Choose low-salt Cajun seasoning to avoid an overly salty dish; brands vary widely in salt content.
- Shrimp cook very quickly. Remove them from heat as soon as they turn opaque and curl slightly into a “C” shape.
- To reduce richness without losing creaminess, substitute half-and-half for heavy cream.
- Add red pepper flakes or extra cayenne if you like more heat.
FAQ’s
Which type of pasta is best?
Any pasta shape will work with this sauce. Thin linguini was used here, but penne catches sauce well, and spaghetti or angel hair are fine substitutes depending on what you have on hand.
What’s the best shrimp to use?
Peeled and deveined shrimp are most convenient. Wild-caught shrimp often have better flavor and texture than some farmed varieties, and larger shrimp generally provide more satisfying bites. Keep frozen shrimp on hand for quick meals—thaw overnight in the fridge or run under cold water to defrost quickly.
Can I use other protein?
Yes. White meats such as chicken or scallops adapt well to this sauce, and tofu is a good vegetarian option. If you choose a different protein, adjust cooking times accordingly and add a touch more Cajun seasoning to keep the flavor bold.
