Heat a large skillet over high heat. Add ground beef, breaking apart, and cook for 5-6 minutes until browned. Drain any grease away. Add taco seasoning and water called for on the packet. Simmer for a few minutes until the liquid is absorbed. Remove from heat.
1 pound ground beef, 1 package taco seasoning
Wrap corn tortillas in a towel and microwave for 1 minute.
8 corn tortillas
Working in batches, fill 4 of the tortillas with ground beef and cheese.
1 1/2 cups shredded cheddar cheese
Fold in half to form a taco and brush the outside with olive oil.
1 Tablespoon olive oil
Place in the air fryer basket in a single layer. You can use a toothpick to hold them closed, or if you have an Instant Pot, the trivet works well to place on top to stop them from opening up.Cook at 400º F for 8 minutes, flipping half way.
Remove the cooked ones and repeat with the rest of the ingredients.
Top the cooked tacos with whatever your favorite taco toppings are.
Lettuce, Tomatoes, Black Olives, Sour Cream
Notes
If your tacos open up with the circulation of air, use toothpicks to hold them closed during the first cook time. After you flip, you should be able to remove them.
