How to Make Cajun Shrimp Crab Mac Cheese

Prepare the Shrimp

Let’s kick things off with the shrimp! In a medium bowl, toss the peeled and deveined shrimp with olive oil, Cajun seasoning, salt, and black pepper. I recommend using your hands to make sure every shrimp gets a nice coating of that spicy goodness. Heat a large skillet over medium heat. Once hot, add the seasoned shrimp and cook them for about 4 to 6 minutes. You’ll know they’re done when they turn pink and opaque. This is where the magic happens—your kitchen will smell heavenly! Once cooked, remove the shrimp from the skillet and set them aside. This first step sets the tone for your delicious Cajun Shrimp Crab Mac Cheese!

Cook the Pasta

Next up: the macaroni! Bring a large pot of salted water to a boil over high heat. When it’s bubbling like a hot spring, add the elbow macaroni. Cook it until al dente according to the package instructions. This means it should be just firm enough to still have a bite. Trust me, you don’t want mushy pasta! Once it’s cooked, drain the macaroni thoroughly and transfer it to a huge mixing bowl. The pasta is now ready to become the base of this flavor-packed dish.

Combine Ingredients

Now it’s time for the fun part! Gently fold the cooked Cajun shrimp into the pasta, along with the crab meat and basil. Stir slowly to avoid breaking the shrimp or crab. The idea here is to let all those delicious flavors mingle together. Imagine the shrimp and crab getting cozy with the macaroni! Once well mixed, you’ll see how the seafood beautifully complements the pasta. Set this medley aside while we whip up the cheese sauce.

Create the Cheese Sauce

Now for the heart of the dish—the creamy cheese sauce! In a large bowl, combine the whole milk and evaporated milk. This duo is your secret weapon for creaminess. Sprinkle in the paprika and cayenne, tasting as you go to adjust the heat level. Whisk in the beaten eggs until they’re fully incorporated. Next, reserve some shredded sharp cheddar, Colby, Monterey Jack, and Parmesan cheese for topping later. Add the remaining cheeses to the milk mixture, stirring until everything is melted and blended. When the cheese sauce is thick and luscious, it’s ready to embrace the pasta and seafood. Hold onto your forks; it’s about to get decadent!

Assemble and Bake

Let’s bring it all together! Start by pouring that rich cheese sauce into the bowl with the pasta and seafood. Give it a good stir to ensure everything is coated generously. Next, spoon the mixture into a lightly buttered 9×13-inch baking dish. Now, scatter the reserved cheeses on top—this is where it gets cheesy! For a finishing touch, sprinkle extra Cajun seasoning or herbs if you desire. Preheat your oven to 350°F (177°C) and bake for 45 to 55 minutes. When the top is golden and bubbly, remove it from the oven, and let it sit for about 25 to 30 minutes. This will help the dish thicken up perfectly!

Tips for Success

Use fresh shrimp for the best flavor; frozen works in a pinch!
Don’t overcook the pasta; al dente is key for the best texture.
Let the dish rest after baking; it helps the cheese sauce thicken and set.
Feel free to adjust the Cajun seasoning to suit your family’s taste preferences.
Make it ahead! This dish can be assembled and refrigerated before baking.

Equipment Needed

Large Skillet: A non-stick or cast-iron skillet works wonders for cooking the shrimp.
Large Pot: Essential for boiling the macaroni; any sturdy pot will do.
Mixing Bowls: A couple of medium to large bowls for mixing ingredients.
Baking Dish: A 9×13-inch baking dish is ideal; any comparable size will work.
Whisk: Perfect for blending your cheese sauce; a fork can also suffice.

Gluten-Free Option: Use gluten-free elbow pasta to make this dish suitable for gluten-sensitive diets. It’s a delicious alternative that everyone will love.
Different Cheeses: Experiment with your cheese blend! Try adding Gouda or pepper jack for a unique flavor profile that elevates the dish.
