Sheet Pan Steak Fajitas

Sheet pan steak fajitas take me right back to a busy weeknight when I wanted something bold and flavorful but didn’t want to stand over the stove so I decided to try tossing everything onto a single pan and let the oven do all the work and when I pulled it out and saw the sizzling peppers and perfectly cooked steak I knew I had found a new go-to and the first bite, wrapped in a warm tortilla with a squeeze of lime, made me feel like I was at my favorite local Mexican spot.

Ever since then, sheet pan steak fajitas have been my favorite way to make a quick, colorful, and satisfying dinner and I love how the peppers get caramelized edges and the steak stays juicy and tender and it’s all finished with fresh cilantro and a burst of lime that makes the whole dish pop and it’s perfect for feeding a crowd or enjoying as a fun weeknight treat that’s both easy and impressive.

Ingredients

• Here’s what I use for this recipe. You can always make substitutions if you prefer!
• Flank steak – Tender, flavorful strips that cook quickly and soak up all the spices.
• Bell peppers – Add sweetness, color, and a perfect char when roasted.
• Onion – Brings mild sweetness and depth to the mix.
• Olive oil – Helps everything caramelize beautifully in the oven.
• Lime juice – Brightens the final flavor and ties everything together.
• Chili powder – Adds warmth and a mild kick.
• Cumin – Brings an earthy, smoky note.
• Paprika – Adds gentle heat and color.
• Garlic powder – Infuses everything with savory flavor.
• Salt – Enhances all the spices and ingredients.
• Black pepper – Gives a subtle heat and depth.
• Fresh cilantro – Adds a fresh and vibrant finish.

Tools You’ll Need

• Sheet pan – The star of this recipe, perfect for roasting everything at once.
• Knife – For slicing the steak, peppers, and onion.
• Cutting board – Keeps everything neat and safe during prep.
• Mixing bowl – To toss the steak and veggies with the seasonings.
• Tongs – For flipping and mixing the ingredients on the pan.
• Citrus juicer (optional) – Makes squeezing lime juice even easier.

Instructions

Step 1

I start by preheating the oven to 425°F so it’s hot and ready to roast everything quickly.

Step 2

In a large bowl I combine the olive oil, lime juice, chili powder, cumin, paprika, garlic powder, salt, and black pepper to make a flavorful marinade.

Step 3

I add the sliced flank steak, bell peppers, and onion to the bowl and toss everything well so all the pieces are coated evenly.

Step 4

Next I spread the steak and veggies out on a large sheet pan in a single layer so they roast instead of steam.

Step 5

I bake for about 15-20 minutes, stirring halfway through to make sure everything cooks evenly and the edges get a nice char.

Step 6

Once out of the oven I sprinkle fresh cilantro over the top and squeeze extra lime juice for a bright finish.

Step 7

Finally I serve the fajitas in warm tortillas with extra toppings like avocado, salsa, or sour cream if I’m feeling fancy.

Tips

If you want even more flavor I recommend marinating the steak for a few hours or overnight before baking. I also sometimes add sliced jalapeños for an extra kick. And for a low-carb option, serve the fajitas over a bed of lettuce or cauliflower rice!

Ways to Serve

I love serving sheet pan steak fajitas family-style with a stack of warm tortillas and all the fixings on the side so everyone can build their own. They’re also great on top of rice bowls or even stuffed into quesadillas for a fun twist.
