Ingredient Guide

• Large shrimp (¾ to 1 lb): Peeled and deveined for a tender, juicy bite. Choose wild-caught if you can for the best flavor.
• Lump crab meat (8 oz): Adds sweet, delicate contrast to the spicy sauce. Fresh or canned both work well.
• Pasta (12 oz): Fettuccine, linguine, or penne—pick your favorite shape that holds sauce beautifully.
• Cajun seasoning (1 tbsp divided): The heart of the dish. It layers in warmth and a touch of smoky heat. Use your go-to blend or homemade.
• Garlic (4 cloves minced): Aromatic base that enhances every element.
• Olive oil (1 tbsp): For searing shrimp and adding richness.
• Butter (2 tbsp divided): Deepens flavor and creates a silky sauce.
• Heavy cream (1 cup): Makes the sauce luxuriously creamy.
• Parmesan cheese (½ cup grated): Adds nutty, salty depth.
• Lemon juice (1 tbsp): Brightens and balances richness with fresh zing.
• Salt & black pepper: Essential for seasoning throughout.
• Green onions or parsley (¼ cup chopped): Fresh garnish for color and brightness.
• Reserved pasta water: An easy trick to loosen sauce and help it cling.

Prep Before You Begin

It’s all about setting yourself up for a smooth cooking flow. I always like to get the pasta boiling first so it’s ready when I need it. While the water’s heating up, I measure out the Cajun seasoning and chop garlic, so everything is easy to grab. Having your mise en place ready will keep this recipe feeling fun, not frantic. You won’t need the oven here, so everything happens on the stove—a quick and satisfying way to build flavor.

How to Make Cajun Shrimp and Crab Pasta Recipe

1. Cook pasta in plenty of salted boiling water until just al dente. This takes about 9–11 minutes depending on your pasta type. Don’t forget to reserve ½ cup of pasta water before draining—it’s a handy secret to perfect sauce texture.
2. Toss the shrimp with 1 teaspoon of Cajun seasoning and a pinch of salt. This simple step guarantees flavorful bites that are never bland.
3. Heat olive oil in a large skillet over medium-high heat. Sear the shrimp about 1 to 2 minutes per side, until lightly crisp and opaque. Avoid overcrowding the pan so they cook evenly. Transfer shrimp to a plate and set aside.
4. Add 1 tablespoon butter to the skillet. Gently warm the lump crab meat—taking care not to break it up too much. The goal is to heat through while preserving that delicate, flaky texture. Remove and set aside with shrimp.

Expert Tips to Nail It

Tip 1: Don’t overcook your shrimp—they’ll continue cooking off the heat and become rubbery if left too long.
Tip 2: Use reserved pasta water sparingly; it adds starch to help the sauce coat the pasta but can thin it out if overused.
Tip 3: Warm your crab gently to avoid toughening it—low heat is key here.

5. Add remaining butter and garlic to the same skillet. Sauté just 30 seconds until fragrant and golden—this sizzling aroma makes your kitchen smell irresistible. Stir in the remaining Cajun seasoning to toast the spices and build depth.
6. Pour in the heavy cream slowly, stirring to combine. Let it simmer gently for 3 to 4 minutes so it thickens slightly and the flavors meld beautifully.
7. Whisk in Parmesan cheese and lemon juice until the sauce is smooth and glossy. Season with salt and black pepper to taste. The cheese adds creaminess and subtle savory notes, while lemon cuts through the richness to balance every bite.
8. Return cooked pasta, shrimp, and crab to the skillet. Toss everything together to coat evenly in that velvety Cajun sauce. If the sauce feels too thick, stir in reserved pasta water a little at a time until you reach your perfect consistency.
9. Garnish with chopped green onions or parsley for a pop of color and fresh brightness. Serve immediately while it’s warm, creamy, and just begging to be enjoyed.

Creative Variations for Cajun Shrimp and Crab Pasta Recipe

• Add diced bell peppers or cherry tomatoes in step 5 for extra color and sweetness.
• Swap shrimp for scallops or lobster tails for a decadent twist.
• Use coconut cream instead of heavy cream for a subtle tropical note.
• Incorporate spinach or kale at the end for a healthy, vibrant touch.
• Boost heat with a pinch of cayenne or fresh chopped jalapeño if you like it spicy.
• Try gluten-free pasta or spiralized zucchini noodles for a lighter version.

Storage, Freezing & Reheating

• Refrigerate leftovers in an airtight container for up to 3 days.
• Freeze in portions: Cool completely, then freeze up to 1 month. Thaw overnight before reheating.
• Reheat gently: Warm in a skillet over low heat with a splash of cream or pasta water to refresh the sauce.
• Avoid microwave overheating to prevent rubbery shrimp; reheating slow and low preserves texture.
