Ground Beef Fajitas

These easy 30 minute Ground Beef Fajitas have spicy chipotle ground beef with mounds of roasted bell peppers and onions. You will never make your tacos the same way again. This recipe was originally called Go To Weeknight Beef Tacos with Peppers, but I changed the name to reflect the recipe better.

In the spirit of eating more vegetables, I added my favorites (bell peppers and onions) to a beef taco. Are these technically fajitas, or are they tacos with peppers and onions? I don’t know, but they are pretty good.

They only take 30 minutes to make, making them perfect for a quick and delicious weekday dinner.

To season the vegetables and beef, I made a spice mixture with cumin, chipotle chili powder, salt, and garlic powder. It’s smokey and spicy.

This recipe is simple and straightforward, but to get the most flavor out of the beef, you’ll want to make sure your meat gets a deep brown color. You can do this by cooking on medium high heat and not moving the meat around too much. Those brown bits have a ton of flavor and make the meat extra tasty.


  • Chili Powder: If you don’t have chipotle chili powder or can’t find it in the store, chili powder is a good substitute. It’s basically the same, but chipotle powder has a nice smokiness to it, and it has a little more heat to it.
  • Spicy Guacamole: You can smash up an avocado, and add a pinch of salt, and call it a night, but I LOVE adding in a splash of lime juice and red pepper flakes to my guacamole.
