Ingredients for Sheet Pan Beef Fajitas

Here’s what you’ll need to create this vibrant dish:

Tip: Flank steak is the best cut for fajitas because it’s lean, flavorful, and cooks quickly. Just make sure to slice it thinly against the grain for maximum tenderness.

How to Make Sheet Pan Beef Fajitas

This recipe is designed to be quick, simple, and practically foolproof.

Step 1: Prep & Preheat

Preheat your oven to 400°F (200°C). Thinly slice the flank steak, bell peppers, and onion. Place everything in a large mixing bowl.

Step 2: Season

Drizzle the olive oil over the steak and vegetables. In a small bowl, combine the chili powder, cumin, garlic powder, onion powder, paprika, salt, and black pepper. Sprinkle the seasoning mix over the ingredients and toss until everything is evenly coated.

Step 3: Roast

Spread the mixture evenly onto a large sheet pan. Roast in the preheated oven for 20–25 minutes, or until the steak is cooked to your liking and the vegetables are tender.

Step 4: Finish & Serve

Remove from the oven and drizzle with fresh lime juice. Serve hot with warm tortillas and your favorite toppings like sour cream, guacamole, salsa, or shredded cheese.

Best Toppings for Beef Fajitas

One of the joys of fajitas is customizing them with toppings. Here are some delicious add-ons:

• Guacamole or sliced avocado for creaminess

• Sour cream or Greek yogurt for tang

• Shredded cheese for richness

• Fresh cilantro for brightness

• Salsa or pico de gallo for freshness and spice

• Pickled jalapeños for heat

Tips for Perfect Sheet Pan Fajitas

1. Slice evenly: Cutting your steak and veggies into uniform strips ensures everything cooks at the same rate.

2. Don’t overcrowd: Spread everything in a single layer on the sheet pan. Overcrowding causes steaming instead of roasting.

3. Use high heat: The 400°F oven helps caramelize the peppers and onions for maximum flavor.

4. Rest the steak: Let the fajitas rest for 5 minutes before serving to lock in juices.

5. Meal prep friendly: Store leftovers in airtight containers for up to 3 days. Reheat in a skillet or microwave.

What to Serve with Beef Fajitas

While tortillas are the classic companion, you can turn your fajitas into a full feast with sides like:

• Mexican rice or cilantro lime rice

• Refried beans or black beans

• Corn on the cob or Mexican street corn (elote)

• A fresh salad with lime vinaigrette

Make It Your Own

• Low-carb option: Skip the tortillas and serve fajitas in lettuce wraps or over cauliflower rice.

• Extra heat: Add cayenne pepper, chipotle powder, or sliced jalapeños to the seasoning mix.

• Vegetarian version: Swap steak for portobello mushrooms, extra peppers, or tofu.

• Chicken fajitas: Replace flank steak with sliced chicken breast or thighs.

Storage and Reheating

• Refrigerator: Store cooked fajitas in an airtight container for up to 3 days.

• Freezer: For longer storage, freeze the cooked mixture in freezer bags for up to 2 months.

• Reheating: Warm in a skillet over medium heat or microwave in short bursts to avoid overcooking.
