Cook the Ground Beef:

• Heat the olive oil in a large skillet over medium heat.

• Add the chopped onion and cook for 3-4 minutes, until softened.

• Add the minced garlic and cook for another 1 minute until fragrant.

• Add the ground beef to the skillet and cook, breaking it up with a spoon, until browned and cooked through (about 6-7 minutes). Drain any excess fat if necessary.

Season the Beef:

• Add the chili powder, cumin, smoked paprika, oregano, and cayenne pepper to the beef mixture. Stir well to coat the meat with the spices.

• Pour in the diced tomatoes and beef broth (or water). Stir and bring to a simmer.

• Let the mixture cook for 10-12 minutes, allowing the flavors to meld and the liquid to reduce. Season with salt and pepper to taste.

Warm the Taco Shells:

• While the beef mixture is simmering, warm your taco shells according to the package instructions (either in the oven, on a skillet, or microwave).

Assemble the Tacos:

• Spoon the seasoned beef mixture into each taco shell.

• Top with your desired toppings such as shredded lettuce, chopped tomatoes, shredded cheese, sour cream, salsa, cilantro, and jalapeño slices.

Serve:

• Serve the Chilli Beef Tacos immediately with your favorite side dishes like rice, guacamole, or tortilla chips. Enjoy!
