Why I Love This Recipe

The best part of this recipe, besides how tasty it is, is how quickly it all comes together. All you need is some chicken, bell peppers, onions, and a few spices you probably already have in your kitchen. The great thing about sheet pan dinners is that you can throw everything on the pan, stick it in the oven, and walk away. No need to stand over the stove stirring or flipping. It’s simple and stress-free, and who doesn’t love that?

Plus, fajitas are super versatile. You can serve them with tortillas, over rice, or even in a salad for a lighter option. There’s no wrong way to enjoy them!

Ingredients You’ll Need

Before we get started, let’s gather everything you need for this easy chicken fajita recipe. Here’s what you’ll need:

• Chicken breast or thighs (I prefer chicken breast for this recipe, but thighs work too if you like a juicier, more flavorful option)
• Bell peppers (I like to use a mix of red, yellow, and green for color, but use whatever you have on hand)
• Onions (You can use yellow or red onions—totally up to you!)
• Fajita seasoning (You can buy a pre-made mix or make your own with chili powder, cumin, garlic powder, onion powder, paprika, and salt)
• Olive oil (This helps everything roast beautifully and keeps it from sticking to the pan)
• Lime (Freshly squeezed lime juice adds the perfect tang to balance the flavors)
• Tortillas (I like flour tortillas for this recipe, but feel free to use corn or even lettuce wraps if you’re looking for a gluten-free option)

How to Make These Sheet Pan Chicken Fajitas

Making these fajitas couldn’t be easier. Here’s how it’s done:

Step 1: Preheat Your Oven

I always start by preheating my oven to 400°F (200°C). A hot oven is key to getting those perfect roasted veggies and chicken.

Step 2: Prepare Your Chicken and Veggies

Next, slice the chicken into strips about the same size as your bell peppers and onions. This ensures everything cooks evenly. Then, slice the peppers and onions into strips as well.

Once you have everything prepped, toss the chicken and veggies in a little olive oil and fajita seasoning. I use about 2 tablespoons of fajita seasoning for a good kick of flavor, but you can add more or less depending on how much spice you like. Toss it all together in a large bowl until everything is evenly coated.

Step 3: Spread Everything on the Sheet Pan

Now, lay everything out on a sheet pan in a single layer. Don’t overcrowd the pan, or your chicken and veggies won’t roast properly. It’s important to give them some space so they get that nice roasted texture.

Step 4: Roast in the Oven

Pop the sheet pan in the oven and roast for 20–25 minutes, stirring halfway through to ensure even cooking. You’ll know it’s ready when the chicken is fully cooked through (it should reach an internal temperature of 165°F) and the veggies are tender and slightly caramelized.

Step 5: Squeeze Lime Juice

Once everything is done, take the sheet pan out of the oven and squeeze some fresh lime juice over the top. It really brightens up the flavors and gives everything a nice zesty finish.

Step 6: Serve and Enjoy

Now for the fun part: serving! You can serve these fajitas in soft flour tortillas, over rice, or even in a salad. Add a dollop of sour cream, some salsa, and maybe a sprinkle of cheese if you’re feeling fancy. The options are endless!

Tips for Making the Best Sheet Pan Chicken Fajitas

• Use chicken thighs for extra flavor: While chicken breast is lean and works great in this recipe, chicken thighs have a little more fat, making them extra juicy and flavorful. If you’re up for it, give them a try!
• Customize your veggies: If you have other veggies in your fridge like zucchini or mushrooms, feel free to toss them on the sheet pan too. They’ll roast up beautifully alongside the peppers and onions.
• Make your own fajita seasoning: If you have the spices on hand, mix up your own fajita seasoning with chili powder, garlic powder, cumin, paprika, and a little salt. It’s a great way to control the flavor and adjust the heat level to your liking.
• Serve with toppings: Don’t forget the toppings! Fresh cilantro, a squeeze of lime, or even some guacamole can take these fajitas to the next level.

Why Sheet Pan Dinners Are a Game-Changer

I can’t get enough of sheet pan meals. They’re such a life-saver, especially on busy nights when you’re trying to get dinner on the table without a lot of fuss. These types of meals are quick, easy, and so convenient. Plus, you only have one pan to clean! And let’s be honest, less cleanup means more time for you to relax and enjoy your meal.

With sheet pan dinners like this one, you don’t have to sacrifice flavor for ease. Everything comes together with just a little prep, and the oven does the rest of the work.
