Skillet Beef Fajitas is easy enough for weeknights and festively simple to prepare for casual gatherings too. Beef seasoned with flavors of lime, cumin, and smoke fills warm tortillas with mushrooms and peppers for a delicious one-skillet supper. We’ve served these fajitas countless times for parties and the spiced fragrance is always the first to welcome friends and family the moment they arrive.
You’ll love how versatile this dish is too. The meat and vegetables can be prepped up to three days in advance to save even more time on a busy weekday. Want to boost the vegetables? Increase the mushrooms and colorful peppers as a sub for some of the beef, or toss in a cup of cherry tomatoes. You can even use Bibb or romaine lettuce leaves as an alternative to flour tortillas—think beef fajita lettuce wraps.
Sizzling beef in a hot pan appeals to my sense of accomplishment, as though it’s offering applause for the effort. That’s when I scoop up some guacamole in a chip and bask in the satisfaction of ending the day with a great meal.

- Stir-in the mushrooms and cook for 3 minutes, or until mushroom wilt and release moisture. Add the bell pepper and sprinkle the lime over everything. Allow to simmer uncovered for 2-3 minutes, stirring occasionally.
- Peppers should be only tender, not soft. Sprinkle evenly with 1 tablespoon of Fajita Mix Seasoning and a couple tablespoons of water; stir well to coat with the seasoning and cook another minute. Taste and add more seasoning, as desired. If pan seems too dry add a little more water.
- Warm flour tortillas in the microwave for 1-2 minutes in a tortilla warmer to soften or in a dry skillet over medium-high heat for 30 seconds each side.
- Warm corn tortillas in a dry skillet over medium-high heat for 30 seconds on each side to soften. Fill the warmed tortillas and garnish with sour cream, guacamole, and salsa.
