Heat oven to 400°F (200°C).
In a skillet, sauté onion until translucent. Add ground beef and cook until browned. Drain excess fat if needed.
Stir in taco seasoning, water, and optional tomatoes with chiles. Simmer 5–7 minutes until thickened.
Stand taco shells upright in a baking dish, nestling closely so they stay upright.
Fill each shell about 2/3 full with beef mixture and top generously with shredded cheese.
Bake 10–12 minutes until cheese is melted and shells are crisp.
Add toppings like lettuce, tomatoes, sour cream, avocado, salsa, or cilantro. Serve immediately.
