Preheat air fryer to 400°F, while you prepare the shrimp.
Add the olive oil and lemon juice in a large bowl and whisk together. Add in the shrimp and toss.
Pour in the blackened seasoning and continue tossing, making sure all the shrimp are coated.
Arrange the shrimp in a single layer on your air fryer rack and cook for 5-6 minutes, flipping halfway through cooking if you have the basket type of air fryer.
