How to Make this

Print Recipe (No Advertisments)

1. Bring a large pot of well salted water to a boil and cook the linguine or fettuccine until just al dente, reserve about 1 cup of the pasta water then drain.

2. Pat the shrimp dry and toss with the Cajun seasoning, smoked paprika (if you got it), and a little salt and pepper, let sit while the pasta cooks.

3. Heat 1 tablespoon olive oil in a large skillet over medium-high heat, sear the shrimp 1 to 2 minutes per side until just pink and opaque, then transfer to a plate, dont overcook them.

4. In the same skillet add the remaining olive oil and the butter, reduce heat to medium and sauté the chopped onion and sliced red bell pepper until softened, about 4 to 5 minutes.

5. Add the minced garlic and cook about 30 seconds until fragrant, then pour in the chicken broth to deglaze the pan scraping up any browned bits.

6. Stir in the heavy cream and bring to a gentle simmer, then lower the heat and slowly whisk in the freshly grated Parmesan until the sauce is smooth.

7. Add the lemon juice and crushed red pepper flakes if you’re using them, season with salt and freshly ground black pepper to taste, simmer a minute or two until slightly thickened, add splashes of reserved pasta water if the sauce seems too thick.

8. Toss the drained pasta into the sauce so it gets fully coated, adding more pasta water as needed to loosen and make it silky.

9. Return the shrimp to the pan, toss everything together just to heat the shrimp through, taste and adjust seasoning, then sprinkle with the chopped fresh parsley and serve right away.

Equipment Needed

1. Large pot for boiling the pasta and reserving about a cup of pasta water
2. Colander to drain the pasta
3. Large skillet or sauté pan for searing shrimp and making the sauce
4. Tongs or a pasta fork to toss and serve the pasta, dont squeeze the shrimp too hard
5. Measuring cups and spoons for cream, broth, spices and lemon juice
6. Wooden spoon or silicone spatula for stirring the sauce and scraping the pan
7. Whisk to smooth in the Parmesan and emulsify the cream
8. Chef knife and cutting board for chopping onion, bell pepper and parsley
9. Box grater or microplane for freshly grated Parmesan

FAQ

Q: Can I use frozen shrimp and how do I thaw it safely?

A: Yes. Thaw overnight in the fridge or put the sealed bag in cold water for 20 to 30 minutes, changing water if it gets warm. Pat shrimp very dry before seasoning so it browns instead of steams. Don’t crowd the pan and cook only 1 to 2 minutes per side until pink and just firm or it gets rubbery.

Q: What can I swap for heavy cream or linguine if I don't have them?

A: Linguine or fettuccine can be swapped for spaghetti, penne, or any long pasta. For cream: half and half works if you whisk in 1 teaspoon cornstarch to thicken, or use whole milk with a little cream cheese to add body. Non dairy milks will change the flavor and may be thinner, so add a splash of broth and reduce it down.

Q: How do I control the spice level?

A: Start with 1 tablespoon Cajun seasoning and add more to taste. Skip the red pepper flakes if you want mild. Smoked paprika adds flavor not heat, so you can use it freely. Taste the sauce before adding shrimp and adjust, you can always add more but you can't take it away.

Q: My cream sauce sometimes breaks or gets grainy how do I stop that?

A: Keep the heat low. Don’t boil the cream, just simmer gently. Add grated Parmesan off the high heat and stir till melted. If sauce looks thin, toss in a few tablespoons of reserved pasta water to emulsify. A little butter at the end helps make it silky.

Q: Can I make this ahead or freeze leftovers?

A: Make components ahead but avoid freezing the fully sauced dish. Cook pasta al dente and toss with a little oil, store separately in the fridge up to 2 days. Cook shrimp just shy of done and refrigerate separately. Reheat gently in a skillet with a splash of broth or cream. Sauced pasta can get grainy after freezing, so I don't recommend freezing it.

Q: Any time saving tips for a weeknight version?

A: Use pre-peeled shrimp, jarred minced garlic, and pre-shredded Parmesan. Cook pasta while you sauté onion and pepper, then shrimp. You can finish sauce in the same pan to save cleanup. It comes together in about 20 to 25 minutes if you prep first.

Creamy Cajun Shrimp Pasta Recipe Substitutions and Variations

(Linguine or fettuccine) Substitute with 12 oz penne or rigatoni. They hold the creamy sauce nicely and cook in about the same time, just watch for al dente so it doesn’t get mushy.
(1 lb large shrimp) Substitute with 1 lb boneless chicken breast or thighs, cut into bite sized pieces. Sear until cooked through (165 F) and then finish in the sauce so it stays juicy.
(1 cup heavy cream) Substitute with 1 cup half and half plus 2 tablespoons melted butter for similar richness, or use 1 cup full fat coconut milk for a dairy free option.
(1/2 cup Parmesan) Substitute with 1/2 cup grated Pecorino Romano for a sharper, saltier bite, or use 3 to 4 tablespoons nutritional yeast if you want a vegan, cheesy flavor.

Pro Tips

– Pat the shrimp really dry and let them sit with the seasoning for a few minutes so the spice sticks better. Dont crowd the pan when searing or they will steam instead of getting that nice color. A quick one to two minutes per side is usually plenty since they keep cooking a bit after you pull them off.

– Use more reserved pasta water than you think you need and add it slowly while tossing the pasta. The starch in the water is what makes the sauce silky, so if the sauce looks too thick a few splashes will fix it fast without watering down the flavor.

– Grate the Parmesan fresh and add it off the heat or on very low heat, whisking slowly so the cheese melts into the cream and doesnt get grainy. If your sauce looks like it might split, take it off the heat and whisk in a small spoonful of warm pasta water first.

– Taste and balance near the end. Add lemon juice and a final pinch of salt at the finish, not at the start, because acidity wakes up the dish. If it needs a little kick use crushed red pepper flakes, if it tastes flat add a tiny bit more cheese or a splash of broth, and finish with fresh parsley for brightness.
