How to Make Cajun Shrimp Tacos with Avocado Sauce

Prepare the Avocado Sauce: Cut 1 ripe avocado in half, remove the pit, and scoop the flesh directly into a food processor. Peel and roughly chop 2 cloves of garlic, along with ⅓ cup of fresh cilantro. Squeeze the juice from 1-2 large limes to gather 3 tablespoons of juice. Add these ingredients to the processor, along with ⅓ cup of full-fat sour cream, ¼ tsp. of kosher salt, and 2-3 tbsp. of water. Puree this mixture until smooth and creamy. If it’s too thick, add a little more water as needed to reach your desired consistency.
Prepare the Shrimp: If your shrimp are frozen, thaw them before you start. Once thawed, peel and devein them if you haven’t done so already, discarding shells and veins. Place your shrimp on a paper towel-lined plate to absorb any excess moisture.
Season the Shrimp: Mince 2 cloves of garlic and set aside. Heat a large skillet over medium-high heat. Drizzle in 2 tbsp. of olive oil and let it heat up. Once hot, add the shrimp, followed by 2-3 tsp. of Cajun seasoning, ¼ tsp. of kosher salt, and ⅛ tsp. of pepper. Sauté for about 2-3 minutes until the shrimp are opaque on the first side.
Finish Cooking the Shrimp: Flip the shrimp over and toss in the minced garlic. Continue to cook for another 2-3 minutes, or until the shrimp are cooked through and the garlic releases its fragrant aroma. Remove from heat and set aside.
Prepare the Beans: In a small pan, heat 1 can of refried black beans (or your choice of beans) on the stove according to the package instructions. Stir occasionally until heated through.
Assemble the Tacos: Warm your tortillas — you can do this in a dry skillet for a minute or two on each side. On each tortilla, spread a generous layer of the heated beans, add a portion of the sautéed Cajun shrimp, and drizzle with the creamy avocado sauce. Feel free to garnish with your choice of fresh veggies, mango, or even a splash of salsa for added zing.

Storing & Reheating

Leftovers can be stored at room temperature for up to 2 hours but are best refrigerated if you won’t use them right away. Place the leftovers in an airtight container and refrigerate for up to 3 days. If you’d like to freeze them, wrap the tacos well in plastic wrap and store in a freezer-safe container for up to 3 months. To reheat, microwave the tacos on medium for 1-2 minutes, or until heated through, but keep in mind that the texture might change slightly. A fresh drizzle of avocado sauce will help refresh the taste!

Chef’s Helpful Tips

Avoid Overcooking: Shrimp cook quickly! Watch for them to turn opaque and firm, then remove them from the heat to prevent rubberiness.
Fresh Ingredients: Use fresh garlic and cilantro for the best flavor. Dried herbs won’t give the same impact.
Warm Tortillas: Always warm your tortillas before serving; it makes them more pliable and prevents tearing.
Customize the Heat: Adjust the amount of Cajun seasoning based on your taste preference; you can always add more heat with hot sauce later.
Make Ahead: The avocado sauce can be made a day ahead; just keep it in the fridge and tightly covered to prevent browning.

The bright mixture of Cajun flavors combined with the creaminess of the avocado sauce makes these tacos irresistible. You’ll find yourself wanting to celebrate every gathering or simply treat yourself after a long day with this incredible dish. So gather your ingredients and make these lovely Cajun shrimp tacos tonight—they’re a guaranteed crowd-pleaser!
