Easy Steak Fajitas

You will love making sheet pan steak fajitas. If I can ever convert a recipe to a sheet pan dinner, I am on it.

Quickly sliced steak is tossed with jalapeno, lime juice and simple spices without need to marinate. Strips of bell peppers and onion are seasoned with the same spices as meat. Then everything gets tossed for even flavor right on the sheet pan. Bake, broil and finish with a touch of salt for seasoning and dinner is served.

I like to bake fajitas because it is hands off method, meat and veggies come out juicy and not soggy, house doesn’t smell like fried food and less kitchen clean up.

What Is the Best Steak for Fajitas?

Traditionally fajitas are made with skirt or flank steak. I use the most affordable top sirloin steak from Costco. Beef is expensive and I find with fajitas as long as you slice steak against the grain, meat comes out tender.

How to Make Sheet Pan Steak Fajitas

Cut steak against the grain and slice vegetables: Look at your flank steak, see how the lines are running? Cut across them, not parallel. With sirloin steak it is easy because of its elongated shape – cut across, not lengthwise.
Season meat and veggies: Make 2 separate piles of beef and veggies on one sheet pan. Season and toss each pile separately. Then mix meat and veggies together and transfer half of steak fajitas on second sheet. Spread in a single layer. Baking on 2 pans results in more browned meat and veggies.
Bake in preheated 475 F oven for 20 minutes: To check for doneness, just taste a piece of steak.
Broil until browned: About 5 minutes under 550 F broiler. This is when you have to watch fajitas not to burn.
Season with salt: I underseason fajitas during cooking on purpose because a small sprinkle of salt at the end is everything. Good finishing salt is pink salt or coarse sea salt. Delicious!

Tips for Sheet Pan Steak Fajitas

Health concern: I like to line aluminum pans with silicone baking mats or unbleached parchment paper to prevent aluminum leaching into food.
Different baking sheet: Dark coloured baking pan might cook fajitas faster.
Ovens vary: If you have convection oven by default, it will cook fajitas faster as well.
More heat: Leave some seeds in jalapeno for a heat kick.
Cooking for 2: Feel free to cut recipe in half, use one pan and cook for same amount of time.

Serving and Fixings Ideas

These easy steak fajitas come out so tasty, you don’t even need any toppings. That finishing salt at the end is everything!

Wrap it up: We serve steak fajitas in whole wheat tortillas with sliced avocado, torn pieces of cilantro and a squeeze of lime juice. You can use corn tortillas or white flour tortillas (less nutritious).
Sides and toppings: You can top fajitas with jarred salsa and refried beans on a side. Many enjoy fajitas with sour cream and guacamole. Whenever I have time, I really love fajitas with pico de gallo.

How to Make Ahead and Store

Storing: Refrigerate leftovers in an airtight container for up to 3 days. To reheat, throw on a ceramic non-stick skillet and pan fry until warmed through. It will give fajitas an extra char and refresh them.

Make ahead: Slice vegetables and refrigerate in an airtight container. I wouldn’t recommend to season them yet because salt will pull moisture out. But steak would be great to marinate in seasonings and refrigerate. Prepped meat and veggies should last for up to 3 days. Then cook as per recipe.

Instructions

Preheat oven to 475 degrees F and line 2 rimmed baking sheets (half sheets) with silicone baking mats or unbleached parchment paper.
Cut steak against the grain into thin slices. Look at your flank steak, see how the lines are running? Cut across them, not parallel. With sirloin steak it is easy because of its elongated shape - cut across, not lengthwise.
Also cut onions and bell pepper into thin strips.
Transfer meat and vegetables into 2 separate piles on one sheet pan.
Meat: squeeze lime juice, drizzle with olive oil and sprinkle with taco seasoning, garlic powder, salt and pepper.
Vegetables: drizzle with olive oil and season with taco seasoning, salt and pepper.
Toss each pile to season separately. Then mix meat and veggies together and transfer half of steak fajitas on second sheet. Spread in a single layer.
Bake for 20 minutes. To check for doneness, just taste a piece of steak.
Broil until browned, about 5 minutes under 550 F (high) broiler.
Season meat only just with a pinch of pink, coarse or regular salt. I underseason fajitas during cooking on purpose because a small sprinkle of salt at the end is everything. Good finishing salt is pink salt or coarse sea salt. Delicious!
We serve steak fajitas in whole wheat tortillas with sliced avocado, torn pieces of cilantro and a squeeze of lime juice. You can use corn tortillas or white flour tortillas (less nutritious). You can top fajitas with jarred salsa, sour cream, guacamole or pico de gallo. And refried beans on a side.
