How To Make Cajun Pasta with Shrimp

Cook the pasta according to the package directions, stopping about 2 minutes short of the recommended time so it stays al dente. Drain and set the pasta aside, since it will finish cooking in the sauce.
Melt 1 tablespoon of butter in a large skillet over medium heat. While the butter melts, toss the shrimp with 1 tablespoon of Cajun seasoning so they are evenly coated.
Add the seasoned shrimp to the hot skillet, working in batches if needed, and sauté just until they are barely cooked through. Transfer the shrimp to a plate to keep warm, as overcooking can make them rubbery.
Add the remaining butter to the same skillet, then stir in the green bell pepper, red onion, and garlic. Sauté for 3 to 4 minutes, until the vegetables are tender and fragrant.


Sprinkle the remaining 1 tablespoon of Cajun seasoning over the vegetables and stir to combine. Cook for about 1 minute to lightly toast the spices and deepen their flavor.
Sprinkle the flour over the vegetables and stir well to coat everything evenly. This helps thicken the sauce as it cooks.

Pour in the chicken broth and stir in the tomato paste, scraping up any flavorful bits from the bottom of the pan. Bring the mixture to a simmer and cook for about 10 minutes, until it reduces slightly and thickens.
Reduce the heat to low and stir in the heavy cream. Let the sauce simmer gently for about 5 minutes, until smooth and creamy.

Squeeze fresh lemon juice over the shrimp, then return them to the skillet. The lemon brightens the dish and balances the richness of the sauce.
Add the cooked pasta to the skillet and toss until it is fully coated with the sauce and vegetables. Sprinkle with Parmesan cheese if using, garnish with diced tomato, green onions, and chopped parsley, then serve hot.

Chef Jenn’s Tips
- If you love a little extra heat, don’t be shy about adding more Cajun seasoning! You can also sprinkle a bit of cayenne pepper for an added kick.
- Cooking the shrimp separately ensures that they don’t overcook and become rubbery. Once they turn pink and opaque, remove them from the heat right away.
- Make sure the pasta is just al dente, as it will continue to cook a bit once it’s mixed into the sauce.
- You can adjust the thickness of the sauce by adding a bit more chicken broth if you prefer a looser sauce, or let it simmer longer if you want it thicker.
Make It A Meal
This Cajun Pasta with Shrimp is a complete meal in itself, but if you’re looking to round out the dinner table, serve it with a simple green salad or some crusty garlic bread to soak up the extra sauce. A light side dish like roasted asparagus or steamed broccoli pairs well, balancing the richness of the creamy pasta.

Storage
Leftover Cajun Pasta with Shrimp can be stored in an airtight container in the refrigerator for up to 3 days. When reheating, add a splash of chicken broth or cream to help loosen the sauce and restore its creamy texture.
