Seasoned ground beef tacos loaded with fresh toppings are a quick family dinner everyone loves. High in protein and endlessly customizable, they're perfect for taco night any day of the week.
Heat a large skillet over medium-high heat. Add ground beef and break it up with a spatula as it browns, about 3–4 minutes; drain excess fat if desired.
Add diced onion to the beef and cook until softened, stirring occasionally, about 2–3 minutes.
Reduce the heat to medium. Stir in chili powder, cumin, garlic powder, salt, and black pepper, coating the meat evenly.
Pour in 1/4 cup water, stir, and allow the mixture to simmer for 5–7 minutes until the liquid reduces and beef is flavorful but still moist.
Warm the tortillas in a dry skillet for 30 seconds per side or wrap in foil and heat in a low oven for soft pliability.
Assemble tacos: fill each tortilla with seasoned beef, top with lettuce, tomato, and shredded cheddar cheese. Serve immediately with optional salsa or hot sauce.
