Easy Sheet Pan Steak Fajitas for a Quick Weekday Meal
Like you, I'm always looking for ways to make my family's favorites so we can have dinner on the table with the least fuss. Mexican inspired food is always a win for my boys, who I believe could eat it daily with no complaints. Recipes like my baked chicken taquitos, easy pull apart cheesy taco sliders and frito taco salad are just a few they request often. If you'd like to try your hand at making your own tortillas, checkout this recipe for homemade flour tortillas from Mom on Timeout.
Helpful Tips for Making Sheet Pan Steak Fajitas
- This recipe uses flat iron steaks. You can use flank steak, if that's your preference.
- Adjust the baking time according to the thickness and doneness you prefer. The steaks I used were around ½-3/4 inch thick and took about 8 minutes per side to cook to medium.
- You can test the interior of the steaks with a meat thermometer, if you'd like the steaks to be more rare or more well done. It's your fiesta so, adjust accordingly.
- When checking the temperature insert a meat thermometer from the side pushing to the middle of the steak for the most accurate reading.
- Once rubbed with the seasonings, the steaks will become even more flavorful the longer they chill. Overnight works perfectly, but if you're short on time, at least 2-4 hours.
- The peppers and onion can all be prepped in advance for a time saver. Slice, and place into plastic storage bags then chill until assembling for baking.
- Slice the peppers in similar size thickness for even cooking.
- Serve with sour cream, salsa, pico de gallo, guacamole or any of your favorite fajita toppings.
What Peppers are Best for Fajitas?
You have lots of room here to personalize to your own taste, or you can simply use what you have on hand. I always go for a variety of colors and for this recipe used red, orange, yellow and poblano peppers. I love the color combo but, at times make them with red peppers, poblanos and onion. Go with your personal preference and you'll be good to go.
