Start by heating a skillet over medium heat. Add the ground beef and chopped onion, stirring occasionally for about 5-7 minutes until the beef is browned and the onion is translucent. Next, incorporate minced garlic along with chili powder, cumin, paprika, salt, and pepper. Let it cook for another minute before adding tomato sauce, then simmer for 2 minutes, allowing all the flavors to meld.

While the beef mixture simmers, warm the tortillas to prevent them from cracking when rolling. You can do this by briefly heating them in a skillet for about 30 seconds on each side, or in the microwave for 15-20 seconds. Make sure they're pliable so you can easily fill and roll each tortilla for your Crispy Cheesy Beef Taquitos.

Lay a tortilla flat and spoon about 2 tablespoons of the beef mixture onto the center. Top with a sprinkle of shredded cheese for that extra gooeyness. Carefully roll the tortilla tightly, tucking in the sides as you go, and place it seam-side down on a parchment-lined baking sheet. Repeat this process until all the filling is used.

Preheat your oven to 425°F (220°C) while you finish assembling the taquitos. Once ready, lightly brush each taquito with oil for a crispy finish, and if desired, sprinkle additional cheese on top for extra flavor. Bake in the oven for about 15-18 minutes until they are golden brown and crispy, and consider broiling for an additional 1-2 minutes for that perfect crunch.

Once baked, remove the Crispy Cheesy Beef Taquitos from the oven and let them cool for a few minutes. Serve hot, alongside your favorite dipping sauces such as sour cream, guacamole, or salsa.
