1 lb (450 g) lean ground beef (85/15 or 90/10)
1 small onion, finely diced
1 packet taco seasoning (or ~2 Tbsp homemade blend)
1 cup enchilada sauce + ½ cup (divided)
8–10 tortillas (corn or flour)
2 cups shredded cheese (Mexican blend, cheddar + Monterey Jack, or preferred)
Optional: ½ can black beans (drained), 1 can diced green chilies, corn, sliced jalapeños
Garnishes: chopped cilantro, sour cream, diced tomatoes, sliced green onions
Preheat oven to 375 °F (190 °C). Grease a 9×13″ baking dish.
In a skillet over medium-high, cook ground beef and onion until beef is no longer pink. Drain if needed.
Stir in taco seasoning and ½ cup enchilada sauce. Add optional beans or chilies. Simmer ~2 minutes.
Warm tortillas (microwave or dry skillet) for pliability.
Spoon ~¼ cup filling into each tortilla, top with cheese, roll, and place seam-side down in dish.
Pour remaining sauce over enchiladas, then sprinkle with remaining cheese.
Cover with foil and bake 15 minutes; uncover and bake 5–10 minutes until cheese bubbles and edges crisp.
Rest 5 minutes, garnish, slice, and serve.
Warm tortillas before filling to prevent tearing.
If mixture is too wet, simmer a bit longer or drain some liquid.
Fully baked or unbaked, this recipe freezes well (up to 2–3 months).
For vegetarian version, swap beef for beans, vegetables, or plant-based substitute.
