What Ingredients You Will Need

This recipe uses simple, wholesome ingredients to deliver bold flavor and satisfying texture without the fuss. Most are pantry staples, and substitutions are easy if needed.

• For the Protein:
• 1 lb (450g) boneless, skinless chicken breasts or thighs, sliced thinly (thighs stay juicier)
• OR 1 lb (450g) flank steak or skirt steak, thinly sliced against the grain
• For the Vegetables:
• 1 large red bell pepper, sliced
• 1 large green bell pepper, sliced
• 1 large yellow or orange bell pepper, sliced (adds sweetness and color)
• 1 medium red onion, sliced
• For the Seasoning Mix:
• 2 tsp chili powder (I prefer McCormick for its robust flavor)
• 1 tsp smoked paprika (adds a lovely smoky depth)
• 1 tsp ground cumin
• ½ tsp garlic powder
• ½ tsp onion powder
• ½ tsp dried oregano
• Salt and freshly ground black pepper, to taste
• 1 tbsp olive oil (or avocado oil for higher smoke point)
• Optional Additions:
• 1-2 fresh jalapeños, sliced (for heat lovers)
• Juice of 1 lime (to squeeze over before serving)
• Fresh cilantro, chopped (for garnish)

If you want to make this gluten-free, just double-check your chili powder blend doesn’t have additives. For a dairy-free meal, serve with avocado or salsa instead of sour cream or cheese. And hey, feel free to swap bell peppers for whatever’s fresh or on sale—poblano peppers or even zucchini work well in a pinch.

Equipment Needed

• Baking Sheet or Sheet Pan: A rimmed sheet pan about 12×17 inches works best to hold all the ingredients without crowding. I like using a heavy-duty aluminum sheet pan for even heat distribution.
• Parchment Paper or Silicone Baking Mat: Optional, but highly recommended to prevent sticking and make cleanup a breeze.
• Sharp Chef’s Knife: For slicing your protein and veggies thinly and evenly—makes a big difference in cooking time and texture.
• Mixing Bowl: To toss your ingredients with the seasoning blend. A large bowl helps coat everything evenly.
• Tongs or Spatula: For stirring and flipping halfway through cooking.

If you don’t have a rimmed sheet pan, a large roasting pan or even a cast iron skillet can work, but cooking times might vary slightly. I’ve found that investing in a good-quality sheet pan saves me from uneven cooking and warping over time.

Preparation Method

1. Preheat your oven: Set it to 425°F (220°C). This high heat helps caramelize the veggies and sear the meat nicely.
2. Prepare the protein: Slice your chicken breasts or steak thinly against the grain into strips about ¼ inch (6mm) thick. This ensures tenderness and quick cooking.
3. Slice the vegetables: Cut bell peppers and onion into similar-sized strips—about ½ inch (1.25cm) thick—to cook evenly alongside the meat.
4. Mix the seasoning: In a large bowl, combine chili powder, smoked paprika, cumin, garlic powder, onion powder, oregano, salt, and pepper. Add olive oil and stir to create a paste-like mixture.
5. Toss everything together: Add the sliced meat and veggies to the bowl, and toss until everything is well coated in the seasoning mixture. Use your hands if you want to get in there and really mix it up.
6. Arrange on sheet pan: Spread the meat and veggies out in a single layer on the prepared baking sheet. Avoid overcrowding so things roast instead of steam.
7. Bake: Place the sheet pan in the preheated oven for 20-25 minutes. Halfway through (around 12 minutes), use tongs to flip and stir the meat and veggies for even cooking and caramelization.
8. Check for doneness: Meat should be cooked through (chicken no longer pink inside; steak at your preferred doneness), and veggies should be tender with some charred edges.
9. Finish with fresh touches: If using, squeeze fresh lime juice over the top and sprinkle chopped cilantro before serving.
10. Serve: Offer warm tortillas, guacamole, salsa, and sour cream on the side. Let everyone build their own fajitas—always a crowd-pleaser!

If you notice the veggies are cooking too fast or meat is drying out, reduce oven temperature by 25°F (about 15°C) next time and add a splash of water or broth halfway through baking to keep things juicy. Also, slicing everything evenly is key to avoid overcooked peppers or underdone chicken.

Cooking Tips & Techniques

Let’s face it, making fajitas can sometimes feel fiddly, but this sheet pan approach makes it super straightforward. Here’s what I’ve learned along the way:

• Use thin slices: Whether chicken or steak, slicing thinly against the grain is the secret to tender bites that cook quickly and stay juicy.
• Don’t overcrowd: Give your ingredients room to roast. Crowding traps steam and makes veggies soggy instead of beautifully caramelized.
• High heat is your friend: Roasting at 425°F (220°C) locks in flavors and adds those irresistible browned edges.
• Flip halfway: Stirring and flipping halfway through cooking helps everything brown evenly and prevents sticking.
• Let it rest: After baking, let the meat rest for a few minutes before serving to keep it tender and juicy.
• Customize seasoning: Taste your seasoning mix before tossing to adjust salt and spice levels. Everyone’s heat tolerance is different!

I’ve had my share of overcooked chicken (ugh, dry and tough) before mastering these tips. Now, I never skip the resting step, and it really makes a difference. Also, multitasking by prepping veggies while the oven warms up keeps things efficient—your dinner’s on the table faster than you’d expect.

Variations & Adaptations

One of the best parts about this recipe is how adaptable it is. Here are some ways to make it your own:

• Vegetarian Version: Swap chicken or steak for firm tofu or portobello mushrooms. Marinate tofu in the seasoning mix for extra flavor, then roast with the veggies.
• Spice it Up: Add chipotle powder or cayenne pepper to the seasoning for a smoky, spicy kick. Or include fresh sliced jalapeños on the sheet pan.
• Low-Carb Friendly: Serve fajita filling over cauliflower rice or in lettuce wraps instead of tortillas.
• Slow Cooker Adaptation: Toss everything in a slow cooker on low for 3-4 hours for a hands-off version. The texture will differ (less roasted), but the flavor still shines.
• Personal Twist: I once added pineapple chunks for a sweet-savory combo that my family adored. If you like a little tropical flair, give it a shot!

Serving & Storage Suggestions

Serve these easy sheet pan chicken or steak fajitas hot, straight from the oven, with warm flour or corn tortillas. Add a side of fresh guacamole, salsa, and sour cream (or dairy-free alternatives) for a complete feast. A squeeze of lime and sprinkle of chopped cilantro really bring everything together.

Leftovers store beautifully in an airtight container in the fridge for up to 3 days. Reheat gently in a skillet over medium heat or in the microwave to keep the meat tender and veggies crisp. You can also freeze cooked fajita filling for up to 2 months—just thaw overnight in the fridge before reheating.

Flavors actually deepen after a day or two, making these fajitas perfect for meal prep lunches or easy dinners when you’re short on time. Just pop the filling into tortillas with your favorite toppings, and you’re good to go!
