Start by preheating your air fryer to 400 degrees F. This step is crucial for getting that nice, even cook on the shrimp.

While the air fryer is heating up, take your precooked shrimp and pat them dry with paper towels. This helps the oil and seasonings stick better and ensures a crisper outcome.

In a mixing bowl, toss the shrimp with olive oil or give them a quick spray. Then sprinkle the garlic powder, smoked paprika, sea salt, and black pepper over the shrimp. Toss until they're evenly coated with the seasonings.

Arrange the shrimp in a single layer in the air fryer basket. Remember, we want to avoid overcrowding to allow for proper air circulation.

Cook the shrimp for 4-6 minutes, or until they are heated through and start to get a little golden around the edges. There's no need to flip them halfway, but you can give the basket a gentle shake if you like. If the shrimp are raw and frozen then cook for 10 minutes.

Once done, carefully remove the shrimp from the air fryer and squeeze some fresh lemon juice over them for that zesty kick.

Serve immediately! These shrimp are fantastic on their own or as a protein boost to salads, pastas, or shrimp tacos.
