Sheet-Pan Chicken Fajitas

Today I’m diving straight into Sheet-Pan Chicken Fajitas and I’m letting you in on one of my quickest dinner secrets because I know how busy evenings can get and how comforting it feels to pull a full meal from the oven in just minutes.

I love that everything cooks together on one tray because it makes the process smoother and clean-up easier which frees up more time for actually enjoying dinner.

I find myself coming back to this recipe again and again because the colors the flavors and the simplicity make it a weeknight hero plus it always feels fresh and exciting.

I’m also thrilled to share it with you because I know how satisfying it is to have a no-stress meal ready to serve without hovering over the stove.

So let’s get these sizzling fajita flavors going right from the sheet pan.

Ingredients

Here’s what I use for this recipe and you can always make substitutions if you prefer

• Chicken breasts – They carry the protein and absorb the seasoning beautifully.
• Bell peppers – They bring sweetness color and a tender bite after roasting.
• Onions – They soften in the oven and add a savory caramelized depth.
• Olive oil – Helps everything roast evenly and adds richness.
• Fajita seasoning – This coats the chicken and vegetables with smoky bold flavor.
• Lime – Adds brightness at the end to wake up all the spices.
• Fresh cilantro – For a fresh finishing touch that balances the heat.
• Tortillas – To wrap everything up and make the fajitas complete.

Tools You’ll Need

• Sheet pan – Holds everything in a single layer so it roasts evenly.
• Sharp knife – Helps me slice the chicken and vegetables quickly and uniformly.
• Cutting board – Keeps everything stable and clean while prepping.
• Tongs – I use these to toss the chicken and veggies with seasoning.
• Oven – Roasts everything together to perfection without babysitting.

Instructions

Step 1: Prep the Oven

I start by preheating the oven to 425°F so it’s ready for quick roasting.

Step 2: Slice the Chicken and Veggies

I slice the chicken into thin strips then I cut the bell peppers and onions into long even slices. I like to keep everything similar in size so it cooks at the same speed.

Step 3: Assemble on the Pan

I spread the chicken peppers and onions across the sheet pan making sure they’re evenly spaced. This helps them roast instead of steam.

Step 4: Add Oil and Seasoning

I drizzle the olive oil over the top then I sprinkle the fajita seasoning generously. I toss everything with my tongs until every piece is coated well.

Step 5: Roast

I place the sheet pan in the oven and roast for about 20 minutes. Halfway through I give everything a quick toss so it browns evenly.

Step 6: Finish with Lime

Once everything is cooked I squeeze fresh lime juice over the hot chicken and veggies. It brightens the whole dish instantly.

Step 7: Serve

I warm the tortillas and fill them with the sizzling chicken fajita mixture.

Tips

I’ve found that slicing the chicken very thin helps it cook faster and stay tender. I also like to add extra lime at the table because it lifts the spices even more. For deeper flavor you can marinate the chicken in the seasoning and oil for 30 minutes before cooking. If you love heat toss in a sliced jalapeño for a spicy kick.

Ways to Serve

I love serving these Sheet-Pan Chicken Fajitas in warm tortillas with fresh cilantro and avocado slices because the creaminess balances the spice beautifully. You can also turn them into fajita bowls by spooning everything over rice or quinoa. Sometimes I set out toppings like sour cream shredded cheese pico de gallo or pickled onions so everyone can build their own plate exactly the way they like it which always makes dinner feel more fun and customizable.

Storage Instructions

I store leftovers in an airtight container in the fridge for up to three days and the flavors actually deepen as they sit. When I’m ready to reheat I warm the mixture in a skillet over medium heat so the edges get a little char again. The tortillas can be warmed in a dry pan or microwaved for a few seconds to soften. If I’m planning ahead I freeze the cooked chicken and peppers in a freezer bag and thaw it overnight for super quick meals later on.
