1. Preparing the Filling
- Heat the olive oil in a large skillet over medium heat.
- Add the diced onion, bell pepper, and minced garlic. Sauté for about 5 minutes, or until the vegetables are soft and fragrant.
- Add the ground beef to the skillet. Cook until fully browned, breaking it up with a spatula as it cooks. This should take about 5-7 minutes.
- Stir in the chili powder, ground cumin, dried oregano, salt, and pepper. Cook for another 1-2 minutes to allow the spices to bloom, which enhances their flavor.
- Reduce the heat to low and add the refried beans and tomato sauce. Stir everything together until well combined. Let the mixture cook for another 3-5 minutes until heated through.
- Remove the skillet from heat and allow the mixture to cool slightly before assembling the chimichangas.
2. Assembling the Chimichangas
- Warm the flour tortillas in the microwave for 20-30 seconds to make them more pliable.
- Lay out each tortilla on a flat surface and divide the beef and bean mixture evenly among them, placing the filling in the center.
- Sprinkle shredded cheddar cheese over the filling.
- Fold the sides of the tortilla over the filling, then tightly roll up the tortilla to form a burrito-like shape. Make sure the edges are secure to prevent the filling from spilling out during frying.
- Secure each chimichanga with a toothpick to keep it from unrolling while frying.
3. Frying the Chimichangas
- Heat about 1 inch of oil in a large skillet or deep fryer to 350°F. If you don’t have a thermometer, test the oil by dropping a small piece of tortilla into it—if it sizzles immediately, the oil is ready.
- Carefully place the assembled chimichangas in the hot oil, seam-side down. Fry in batches to avoid overcrowding the skillet.
- Cook each chimichanga for about 2-3 minutes per side, or until golden brown and crispy.
- Use tongs or a slotted spoon to remove the chimichangas from the oil and place them on a paper towel-lined plate to drain excess oil.
- Let them rest for a few minutes before serving. Remember to remove the toothpicks before eating.
