Creamy Cajun Shrimp Pasta Recipe

There’s something magical about the way Cajun spices dance with creamy pasta—each bite is a little celebration of flavor. This dish is my go-to when I want something indulgent yet quick enough for a weeknight. The smokiness of the spices, the plump shrimp, and that velvety sauce? Pure comfort in a bowl.

Ingredients You’ll Need

• 1 lb large shrimp – Peeled and deveined, with tails on or off (your preference!). I love wild-caught shrimp for their sweet, briny flavor.
• 2 tbsp Cajun seasoning – Homemade or store-bought, but check the salt content—some blends are saltier than others.
• 8 oz fettuccine or linguine – The broad noodles cradle the sauce beautifully, but penne works in a pinch.
• 3 cloves garlic – Minced. Because what’s a creamy pasta without garlic’s warm embrace?
• 1 small yellow onion – Finely diced. It melts into the sauce, adding a subtle sweetness.
• 1 red bell pepper – Thinly sliced for a pop of color and crunch.
• 1 cup heavy cream – The lush base of our sauce. For a lighter twist, half-and-half works, but the sauce won’t be as velvety.
• 1/2 cup chicken broth – Lifts the richness and adds depth.
• 1/2 cup grated Parmesan – Freshly grated, please! The pre-shredded stuff won’t melt as smoothly.
• 2 tbsp unsalted butter – For sautéing the shrimp and building flavor.
• 1 tbsp olive oil – Helps prevent the butter from burning.
• Fresh parsley – A handful, chopped. That bright green finish makes all the difference.
• Salt and black pepper – To taste. Go easy on the salt if your Cajun seasoning is already salty.

Let’s Get Cooking

1. Prep the shrimp: Pat them dry with paper towels (this ensures a good sear!), then toss with 1 tbsp of the Cajun seasoning. Let them sit for 10 minutes—this little rest lets the spices cling to the shrimp.
2. Cook the pasta: Boil it in salted water until al dente. Reserve 1/2 cup of the starchy pasta water before draining—it’s gold for adjusting the sauce later.
3. Sear the shrimp: Heat a large skillet over medium-high. Add olive oil and 1 tbsp butter, then cook the shrimp for 1-2 minutes per side until just pink. Don’t overcrowd the pan, or they’ll steam instead of sear! Transfer to a plate and cover to keep warm.
4. Sauté the veggies: In the same skillet, melt the remaining butter. Add onion and bell pepper, cooking until soft (about 5 minutes). Stir in the garlic—just 30 seconds until fragrant, or it’ll turn bitter.

Now, here’s where the magic happens: deglaze the pan with chicken broth, scraping up all those flavorful browned bits. Pour in the cream and remaining Cajun seasoning, letting it simmer gently for 3-4 minutes until slightly thickened. Stir in the Parmesan until melted and silky. If the sauce feels too thick, a splash of reserved pasta water will loosen it perfectly.

FAQs

Can I use frozen shrimp for this recipe?

Absolutely! Just make sure to thaw them completely and pat them dry before cooking to avoid excess moisture in the pan. Frozen shrimp work just as well as fresh in this dish.

What if I don’t have heavy cream?

No worries! You can substitute with half-and-half or whole milk for a lighter version, though the sauce may be slightly less rich. For a dairy-free option, coconut milk adds a lovely depth of flavor.

How spicy is this pasta?

The heat level depends on your Cajun seasoning blend. If you’re sensitive to spice, start with less seasoning and adjust to taste. You can always add more, but you can’t take it away!

Can I add vegetables to this dish?

Of course! Bell peppers, mushrooms, or spinach would be fantastic additions. Sauté them with the onions and garlic for an extra boost of color and nutrition.

How do I store leftovers?

Store in an airtight container in the fridge for up to 2 days. Reheat gently on the stovetop with a splash of cream or broth to revive the sauce’s creaminess.
