Heat a skillet over medium-high heat and add ground beef, diced onion, and minced garlic. Cook for 6-8 minutes, breaking up the beef with a spoon, until no pink remains. Drain excess grease. Stir in cumin, chili powder, salt, and pepper. Let the filling cool slightly for 5 minutes.
1 lb ground beef, 0.5 medium onion, 2 cloves garlic, 1 tsp cumin, 0.5 tsp chili powder, 0.5 tsp salt, 0.25 tsp black pepper
Stack the corn tortillas, wrap them in a damp paper towel, and microwave for 20 seconds to make them pliable and prevent cracking when rolling.
8-12 count corn tortillas
Lay one tortilla flat and spoon 2 tablespoons of the beef filling in a line down the center. Sprinkle 1 tablespoon of shredded cheese on top. Roll the tortilla tightly from one edge to the other, tucking the filling in as you go. Place the rolled taquito seam-side down on a plate. Repeat with remaining tortillas.

Preheat the air fryer to 400°F for 3 minutes. Lightly spray the taquitos with oil on all sides. Place 5-6 taquitos in a single layer in the basket, seam-side down, leaving space between each. Air fry for 10-12 minutes until golden brown and crispy, flipping halfway at 6 minutes for even browning.
to taste oil spray
Remove taquitos from the air fryer and let them rest for 3 minutes to allow the filling to set and prevent spilling. Repeat with remaining taquitos. Serve warm with sour cream, salsa verde, or guacamole.
