Preheat the Oven: Set your oven to 375°F (190°C) to prepare for baking the tacos.
Cook the Beef: In a large skillet over medium heat, add the ground beef. Cook until browned, breaking it apart with a spatula as it cooks. Once browned, drain any excess fat from the skillet.
Sauté Onions and Garlic: Add the finely chopped onion and minced garlic to the pan with the beef. Sauté for about 3-4 minutes, stirring occasionally, until the onion becomes soft and translucent.
Add Spices: Stir in the chili powder, ground cumin, smoked paprika, salt, and pepper. Cook for an additional 2-3 minutes, letting the spices mingle with the meat for a deeper flavor. Remove from heat and set aside.
Prepare Tortillas: In a separate bowl, lightly brush both sides of each corn tortilla with olive oil to help them crisp up nicely during baking.
Assemble the Tacos: Lay the oiled tortillas flat on a baking sheet. Spoon an even portion of the savory beef mixture into the center of each tortilla and sprinkle generously with shredded cheese.
Fold and Arrange: Carefully fold each tortilla in half, gently pressing the edges to secure the filling inside. Arrange the folded tacos on the baking sheet, ensuring they are not overlapping.
Bake the Tacos: Place the baking sheet in the preheated oven and bake for about 15-20 minutes, or until the tortillas are golden and crispy, and the cheese has melted wonderfully.
Cool Slightly: Once baked, remove the tacos from the oven and allow them to cool for a few minutes. This makes them easier to handle.
Serve and Garnish: To serve, generously top each taco with shredded lettuce, diced tomatoes, and avocado. Add a dollop of sour cream on top, and finish with a sprinkle of freshly chopped cilantro for a burst of flavor and color.
Notes
