Follow these simple steps to create amazing beef tacos:

1. Brown the Beef: In a large skillet over medium heat, add the ground beef, breaking it up with a spatula. Cook until browned, about 5-7 minutes.
2. Add Aromatics: Add the diced onion and minced garlic to the skillet. Sauté until the onion becomes translucent, about 3-4 minutes.
3. Season the Beef: Stir in the chili powder, cumin, paprika, salt, and pepper. Cook the mixture for 1-2 minutes until the spices become fragrant.
4. Add Liquid: Pour in the beef broth (or water), stirring to combine. Allow the mixture to simmer for 5 minutes, letting the flavors meld.
5. Warm the Tortillas: While the beef mixture simmers, warm the tortillas in a separate skillet over low heat, or microwave them for 20-30 seconds until pliable.
6. Assemble the Tacos: Scoop a generous portion of the beef mixture onto each tortilla. Top with shredded lettuce, diced tomatoes, and shredded cheese.
7. Finish with Toppings: Add a dollop of sour cream and sprinkle with fresh cilantro.
8. Serve with Lime: Serve with lime wedges on the side for squeezing over the tacos.

Following these steps will lead you to create incredible beef tacos that are bound to impress.
