Heat olive oil in a large skillet over medium-high heat. Once shimmering, add diced onion and cook until softened, approximately 3 minutes, stirring occasionally.
Add minced garlic to the skillet and sauté for 30 seconds until fragrant. The garlic should just begin releasing its aroma without browning.
Add ground beef to the skillet, breaking it apart with a spoon as it cooks. Brown completely over 6-8 minutes, stirring frequently until no pink remains throughout the meat.
Stir in chili powder, cumin, paprika, and cayenne pepper, coating all the meat evenly. Pour in beef broth and simmer 2-3 minutes until the mixture thickens slightly and becomes this 30 minute beef tacos family summer recipe centerpiece.
Warm tortillas by wrapping them in a damp paper towel and microwaving for 45 seconds. Alternatively, heat them directly over a gas flame for 10 seconds per side.

Serve the beef in warm tortillas, allowing everyone to customize their easy quick tacos kids with preferred toppings. This interactive approach makes the meal more engaging for younger diners.
