Ingredients You’ll Need

• 1/2 lb large shrimp (peeled and deveined)
• 1/2 lb lump crab meat
• 2 tbsp Cajun seasoning (adjust to your spice preference)
• 1 tbsp olive oil
• 2 cloves garlic (minced)
• 1 cup heavy cream
• 1/2 cup Parmesan cheese (grated)
• 1 tbsp butter
• Cooked pasta (linguine or fettuccine works great)
• Fresh parsley (for garnish)

Tools You’ll Need

• Large skillet
• Spatula or tongs for sautéing
• Saucepan for cooking pasta
• Cheese grater (if grating fresh Parmesan)
• Measuring cups and spoons

Possible Ingredient Additions and Substitutions

• Chicken: Swap the seafood for chicken breast if you’re looking for a different protein option.
• Vegetarian: Omit the shrimp and crab, and add sautéed mushrooms or spinach for a veggie twist.
• Spice it Up: Add crushed red pepper flakes or a dash of hot sauce for more heat.
• Lighter Version: Substitute half-and-half for the heavy cream to lighten the sauce, though it will be less rich.

Step-by-Step Instructions

1. Cook the Shrimp: Start by seasoning your shrimp with the Cajun seasoning. Heat the olive oil in a large skillet over medium heat, and sauté the shrimp for 3-4 minutes, or until pink and opaque. Remove from the pan and set aside.
2. Make the Alfredo Sauce: In the same skillet, add the minced garlic and sauté for about 30 seconds, just until fragrant. Then, pour in the heavy cream and butter, stirring frequently.
3. Add Parmesan: Stir in the Parmesan cheese and let the sauce simmer for 3-5 minutes, until it thickens slightly. You’ll know it’s ready when it coats the back of a spoon.
4. Combine with Seafood: Gently fold the lump crab meat and cooked shrimp back into the sauce, making sure everything is well-coated and heated through.
5. Serve: Spoon the seafood Alfredo sauce over your cooked pasta of choice. Garnish with freshly chopped parsley and a sprinkle of extra Cajun seasoning if you like.

What to Serve with Shrimp and Crab Alfredo

• Garlic Bread: Perfect for mopping up all that creamy sauce!
• Side Salad: A simple arugula or Caesar salad balances the richness of the pasta.
• Roasted Vegetables: Asparagus or broccoli would add a nice contrast to the rich, creamy sauce.

Tips for Making the Perfect Cajun Alfredo

• Watch the Heat: Be careful not to overcook the shrimp. They turn rubbery if cooked too long!
• Fresh Parmesan: Always use freshly grated Parmesan for the best flavor and a smooth sauce. The pre-grated kind doesn’t melt as well.
• Control the Spice: Cajun seasoning varies in heat. Start with 1 tbsp if you’re unsure, and add more to taste.

Storing and Reheating

• Storage: Leftovers can be stored in an airtight container in the fridge for up to 3 days.
• Reheating: To reheat, add a splash of milk or cream to the pasta while warming it in a skillet over low heat. This keeps the sauce from separating.

FAQ

Can I make this dish ahead of time?

Yes! You can make the sauce a day in advance and store it in the fridge. Reheat it gently in a skillet before serving, adding a splash of milk if necessary.

Can I freeze this Alfredo sauce?

Unfortunately, cream-based sauces don’t freeze well as they tend to separate when reheated. It’s best enjoyed fresh or within a couple of days.

What kind of pasta works best with this dish?

Fettuccine or linguine are classic choices because they hold up well to the rich sauce, but you can use any pasta you prefer!
