How To Make Ground Beef Fajitas

These fajitas are straightforward and fast to prepare. Follow the simple steps below:

Step 1: Cook ground beef

Heat a large skillet over medium-high heat. Add the ground beef and brown it, breaking it up as it cooks. Drain excess fat, sprinkle the fajita seasoning over the meat, stir for another minute or two, then remove the beef from the skillet and set aside.

Step 2: Sauté fajita veggies

In the same skillet over high heat, add the oil. When it shimmers, add the sliced bell peppers and onion. Sauté, stirring occasionally, until the vegetables are tender-crisp and slightly charred, about 5 minutes (longer if you prefer softer veggies). Toward the end, add dried oregano and season with salt and pepper.

Step 3: Add back ground beef

Lower the heat to medium and return the seasoned ground beef to the skillet. Toss gently with the veggies or leave the meat and vegetables on opposite sides and let guests assemble their own fajitas. Squeeze lime juice over the mixture if desired.
