One-Pan Meals

I am a big fan of one-pan meals. So much so, that I have a whole category dedicated to them (Sheet Pan Dinners).

Why? Because the meal prep is usually really simple, I use easy-to-find ingredients and it’s an easy clean up. That’s a perfect combo for coming up with an easy dinner on busy weeknights.

This sheet pan steak fajitas recipe is all of that and more. These fajitas are full of bold flavor and are so easy to prepare. The prep work is minimal and they have a roasting time of less than 15 minutes in the oven.

These sheet pan fajitas are a great option for an easy weeknight meal as well as casual weekend entertaining. And, the great thing is that everyone gets to make their own. They can top them with whatever they like.

Serve them with some tortilla chips, salsa and refried beans for a hearty meal any day of the week.

Making Your Own Homemade Fajita Seasoning

While you could use a store-bought taco seasoning, I think it’s way more interesting to create your own homemade spice blend specifically for these fajitas.

I use chili powder for a little heat as well as cumin and smoked paprika to bring in that smokiness. Garlic powder, salt and pepper bring in a little zing and the fresh lime juice provides that nice citrusy tang. Just a great combination of flavors.

The Best Cut of Steak to Use

I prefer a tender steak with my fajitas, which is why I use sirloin in this recipe. It’s a lean cut of meat, easy to find in the local grocery store and usually priced well.

But, sirloin isn’t the only type of steak you can use in this sheet pan steak fajita recipe. I’ve also made steak fajitas with flank steak and / or a skirt steak. They are a little tougher cuts of meat, but still have great flavor.

I’ve seen other recipes use a hanger steak. A hanger steak tends to be a bit more flavorful than a skirt or flank steak, but also tends to be more expensive.

Bottom line – you have choices!

My Favorite Toppings for Fajitas

There really is no wrong answer here. The great thing about fajitas is the fact that each person can make them their own (that means the whole family can enjoy!).

For me, here are some of my favorite fajita toppings:

Guacamole (If you want it fresh, this recipe is so good!)
Pico de Gallo (This recipe only uses 5 simple ingredients. Easy and tasty!)
Shredded monterey jack cheese
Shredded cheddar cheese
Sour cream
Shredded lettuce
Fresh cilantro
Lime wedges

Tips and Tricks

I start out by mixing the spices together for the seasoning. Once the spices are mixed together, stir in the lime juice which helps the seasoning stick to the steak, peppers and onions. Plus, it gives it everything a little tang.
Make sure that the sheet pan is well-oiled so that the peppers, onions and steak don’t stick.
A hot oven is key to getting a good caramelization on the veggies.
If you want your steak to have a nice sear, it’s important to sear it in a skillet before finishing it in the oven. I’ve tried cooking it entirely in the oven, but it doesn’t get a good sear in the oven.

How to Make Sheet Pan Steak Fajitas

Preheat oven to 475 degrees.
Combine spices together in a small bowl.
Stir lime juice in with the spice mixture.
Toss vegetables with 1 tbsp olive oil and half of the spice mixture.
Coat sheet pan with remaining 1 tbsp olive oil.
Spread veggies in a single layer on sheet pan.
Roast in preheated oven for 8 minutes.
While veggies are roasting, heat a skillet coated with cooking spray over high heat.
Coat steak on both sides with remaining spice mixture.
Sear steak in preheated skillet for 2 minutes per side.
Remove steak from skillet and set aside.
At 8 minutes, add steak to the sheet pan with the veggies, pushing the veggies to the sides of the pan.
Cook for an additional 5 minutes, until veggies are starting to char.
Let steak rest (covered loosely with aluminum foil) for 5 minutes. After 5 minutes, thinly slice on an angle against the grain. If you want, you can leave the veggies on the sheet pan in the oven while cutting the steak – just turn off the heat.
If desired, serve with warm tortillas, salsa, shredded cheese, lime slices and guacamole.
