Ingredients

4 lbs large shrimp, in the shell (21 to 25 count per pound, fresh or frozen)
3 tablespoons Cajun spices
1 tablespoon black pepper
1 tablespoon dried rosemary
1 tablespoon salt
2 teaspoons salt, divided
1/2 lb butter
1 large onion, peeled and finely chopped
6 garlic cloves, peeled and minced
1 cup beer
1 cup extra virgin olive oil
4 tablespoons light brown sugar
1/2 cup Worcestershire sauce
1 lemon, sliced
3 tablespoons fresh lemon juice
3 bay leaves
2 teaspoons dried oregano
2 teaspoons dried thyme leaves
1 teaspoon cayenne pepper
3-5 dashes Louisiana hot sauce

Equipment Needed

Large saucepan
Plastic bag or container
Grill (charcoal or gas)

Instructions

In a small bowl, combine 3 tablespoons of Cajun spice and 1 tablespoon of salt. This is your dry rub for the shrimp, so don’t skimp on the flavor!
Rub the shrimp with the Cajun spice mixture, ensuring each shrimp is generously coated.
Place the seasoned shrimp in a plastic bag or container and refrigerate while you prepare the sauce. This allows the flavors to meld and penetrate the shrimp.
In a large saucepan set over medium-high heat, melt the butter. The aroma of melting butter is the foundation of this incredible sauce.
Add the onion and garlic and cook for 3 to 5 minutes, until soft but not browned. Stir frequently to prevent burning. You want the onions to become translucent and fragrant.
Add the beer, olive oil, brown sugar, Worcestershire sauce, lemon slices, lemon juice, bay leaves, oregano, thyme, cayenne pepper, black pepper, rosemary, and 2 teaspoons of salt to the saucepan.
Stir to combine all ingredients thoroughly. Make sure the brown sugar is completely dissolved.
Reduce the heat to a simmer, cover the saucepan, and cook, stirring occasionally, for about 20 minutes, or until the sauce has thickened slightly. This step allows the flavors to meld and deepen.
Remove the saucepan from the heat, uncover, and cool the sauce to room temperature. This prevents the shrimp from partially cooking when you marinate them.
Remove and discard the lemon slices and bay leaves from the sauce. They have imparted their flavor and are no longer needed.
Pour 1 1/2 cups of the sauce over the shrimp in the bag or container.
Toss the shrimp to coat them well with the sauce.
Cover and refrigerate the shrimp for 1 to 2 hours, allowing them to marinate in the flavorful sauce.
Cover and refrigerate the remaining sauce separately. This is your dipping sauce, so keep it chilled until serving time.
Prepare a charcoal fire or preheat a gas grill for direct grilling over high heat. A hot grill is essential for achieving a beautiful char on the shrimp.
While the grill is heating, reheat the reserved dipping sauce in a small saucepan, making sure it doesn’t burn. Stir frequently and keep it warm, not boiling.
Remove the shrimp from the marinade and discard the used marinade.
Grill the shrimp for 2 to 3 minutes per side, until the shells are pink and the flesh is opaque. The exact cooking time will depend on the size of your shrimp and the heat of your grill.
Don’t overcook the shrimp, or they will become tough and rubbery.
Serve the grilled New Orleans BBQ Cajun Shrimp immediately with the warm sauce for dipping.

Expert Tips & Tricks

Don’t peel the shrimp before grilling! Grilling shrimp in their shells helps to keep them moist and prevents them from overcooking. The shells also impart additional flavor.
If using frozen shrimp, be sure to thaw them completely before marinating. Pat them dry with paper towels to remove any excess moisture.
Adjust the spice level to your preference. If you like it extra hot, add more cayenne pepper or Louisiana hot sauce. If you prefer a milder flavor, reduce the amount of cayenne pepper.
For a richer sauce, use a dark beer like a stout or porter.
If you don’t have a grill, you can also bake the shrimp in a single layer on a baking sheet at 400°F (200°C) for 8-10 minutes, or until they are pink and opaque.
If the sauce becomes too thick while reheating, add a splash of beer or water to thin it out.

Serving & Storage Suggestions

Serve this New Orleans BBQ Cajun Shrimp hot off the grill with the warm dipping sauce. It’s fantastic with crusty bread for soaking up all that delicious sauce. Consider sides like coleslaw, cornbread, or roasted vegetables. Garnish with chopped fresh parsley or cilantro for a pop of color.

Leftover shrimp and sauce can be stored separately in airtight containers in the refrigerator for up to 3 days. Reheat the shrimp gently in a skillet or in the microwave until heated through. Reheat the sauce separately in a saucepan over low heat. It’s best to consume the shrimp within a few days as the texture can deteriorate over time. Freezing is not recommended.

FAQs (Frequently Asked Questions)

Q: Can I use pre-peeled shrimp for this recipe?
A: While you can use pre-peeled shrimp, grilling them in their shells adds flavor and helps prevent them from drying out. If you do use peeled shrimp, reduce the grilling time accordingly.

A: Yes, the sauce can be made a day or two in advance and stored in the refrigerator. This will allow the flavors to meld even further.

Q: What kind of beer should I use?
A: A lager or amber ale works well in this recipe. You can also use a dark beer like a stout or porter for a richer flavor.

Q: Can I bake these in the oven instead of grilling?
