Cajun Shrimp Pasta is a fun and spicy dish that’s sure to please! With juicy shrimp and creamy sauce, it has a kick of Cajun spices that warms you up from the inside out.
I love how quick this meal is to make, ready in just 30 minutes. Perfect for those nights when you want something delicious but don’t have much time—plus, who doesn’t love pasta?
Key Ingredients & Substitutions
Pasta: I usually go for linguine or fettuccine, as their long shape holds the sauce well. If you need a gluten-free option, try using chickpea pasta or zucchini noodles for a lighter twist.
Shrimp: Large shrimp are perfect for this dish, but you can use medium shrimp if that’s what you have. For a vegetarian version, consider using sautéed mushrooms or chickpeas to keep that hearty feel.
Cajun Seasoning: You can buy pre-made Cajun seasoning or make your own with paprika, cayenne, garlic powder, and onion powder. If you’re sensitive to spice, reduce the amount of cayenne.
Heavy Cream: For a lighter version, you can use half-and-half or even a non-dairy cream. I’ve had success with coconut cream for a different flavor profile!
Parmesan Cheese: Freshly grated Parmesan melts better, but pre-grated works in a pinch. Nutritional yeast is a great substitute for a dairy-free option and adds a cheesy flavor.
How Do I Get Perfectly Cooked Shrimp?
Cooking shrimp is quick, and it’s important not to overdo it. Here’s how to make sure they turn out delicious:
- Start with a hot skillet to get a nice sear.
- Add shrimp in a single layer; avoid overcrowding for even cooking.
- Cook for 2-3 minutes on each side; they should be pink and opaque.
- Remove them promptly to prevent overcooking, which makes them rubbery.
By following these tips, you’ll enjoy perfectly cooked shrimp every time!

How to Make Cajun Shrimp Pasta
Ingredients You’ll Need:
For the Pasta and Shrimp:
- 8 oz linguine or fettuccine pasta
- 1 lb large shrimp, peeled and deveined
- 2 tbsp Cajun seasoning
For the Sauce:
- 2 tbsp olive oil, divided
- 3 cloves garlic, minced
- 1 cup cherry tomatoes, halved
- 2 cups fresh spinach leaves
- 1 cup heavy cream
- 1/2 cup grated Parmesan cheese, plus extra for garnish
- Salt and pepper to taste
- Fresh parsley, chopped (optional, for garnish)
How Much Time Will You Need?
This delicious Cajun Shrimp Pasta takes about 30 minutes total. You’ll spend about 10 minutes prepping and cooking the shrimp and sauce, and around 20 minutes boiling the pasta and combining it all into a creamy, flavorful dish.
Step-by-Step Instructions:
1. Cook the Pasta:
Begin by cooking the pasta according to the package instructions until it is al dente. Once it’s cooked, drain it well and set it aside.
2. Season the Shrimp:
In a bowl, toss the peeled and deveined shrimp with Cajun seasoning, making sure they are well coated with the spices. This will give your shrimp that delightful Cajun flavor.
3. Cook the Shrimp:
In a large skillet, heat 1 tablespoon of olive oil over medium-high heat. Once heated, add the seasoned shrimp and cook for about 2-3 minutes on each side, or until they turn pink and are cooked through. After cooking, transfer the shrimp to a plate and set them aside.
4. Sauté the Garlic:
In the same skillet, add the remaining tablespoon of olive oil. Sauté the minced garlic for about 30 seconds, or until it’s fragrant. Be careful not to burn it!
5. Add the Tomatoes:
Now, toss in the halved cherry tomatoes. Cook for 2-3 minutes until they start to soften; this will create a nice flavor base for your sauce.
6. Make the Creamy Sauce:
Pour in the heavy cream and gently bring it to a simmer. This is where your sauce will start to take form!
7. Add the Spinach:
Add in the fresh spinach and cook until it wilts down. It won’t take long, just a minute or two.
8. Combine and Finish the Sauce:
Lower the heat and stir in the grated Parmesan cheese. Keep stirring until it melts beautifully, making your sauce creamy. Season with salt and pepper to taste.
9. Bring It All Together:
Add the cooked pasta and shrimp back into the skillet. Toss everything together so the pasta and shrimp are evenly coated in that delicious sauce.
10. Serve and Enjoy:
Serve the Cajun Shrimp Pasta immediately, garnished with additional Parmesan cheese and fresh parsley if you like. Enjoy the wonderful flavors of this dish!
Bon appétit!
Can I Use Frozen Shrimp for This Recipe?
Yes, frozen shrimp can work just fine! Just make sure to thaw them completely before starting. You can thaw shrimp overnight in the fridge or place them in a sealed bag and submerge in cold water for quicker thawing.
Can I Make This Dish Without Heavy Cream?
Absolutely! If you want a lighter option, you can substitute heavy cream with half-and-half or whole milk. For a dairy-free version, try using coconut milk or cashew cream to keep it rich and creamy.
How Should I Store Leftovers?
Store any leftovers in an airtight container in the fridge for up to 3 days. When reheating, do so gently on the stove or in the microwave, adding a splash of cream or water to help restore the sauce’s creaminess.
Can I Add Vegetables or Substitutes?
Of course! Feel free to add your favorite vegetables like bell peppers, zucchini, or mushrooms for extra flavor and nutrition. Just sauté them with the garlic. If you prefer a vegetarian version, substitute shrimp with chickpeas or grilled tofu.
