Easy Substitutions & Variations:
- Use a different cut of steak: Flank steak, skirt steak, or sirloin all work well; slice thinly against the grain for best texture.
- Make it chicken fajitas: Swap the steak for sliced chicken breast or thighs and roast until the chicken is cooked through.
- Adjust the spice level: Add extra chili powder or a pinch of cayenne for more heat, or reduce the spices for a milder fajita.
- Change the vegetables: Add sliced zucchini or mushrooms, or swap in green bell peppers if that's what you have.
- Serve it low-carb: Skip the tortillas and serve the fajitas over cauliflower rice or salad greens.

How to Make Sheet Pan Steak Fajitas:
- Preheat the oven to 400°F. Drizzle a large sheet pan evenly with olive oil and set aside.
- Place the sliced steak, bell peppers, red onion, and minced garlic directly onto the prepared sheet pan.
- Add the lime juice and zest, chili powder, cumin, oregano, salt, and pepper. Toss everything together on the pan until the steak and vegetables are evenly coated.
- Spread the mixture into a single, even layer so the steak roasts instead of steaming.
- Bake for 14-16 minutes, stirring once halfway through, until the steak is cooked to your liking and the vegetables are tender with lightly charred edges.
- Remove from the oven and serve immediately with tortillas, cauliflower rice, or over salad greens.
Recipe Notes & Tips:
- Slice the steak thinly against the grain: This helps keep the steak tender and easy to chew after roasting.
- Don't overcrowd the pan: Spreading everything into a single layer helps the steak and vegetables roast instead of steam.
- Stir once during cooking: Tossing halfway through ensures even cooking and light charring.
- Adjust doneness to taste: Roast a few minutes less for medium-rare steak or a bit longer for well-done.
- Serving suggestions: Serve with Cilantro Lime Cauliflower Rice or Mexican Coleslaw for a complete fajita night.
