Ingredients
This recipe comes together with a handful of simple ingredients that pack in plenty of flavor. Bell peppers and red onion are the stars, roasting until they’re tender with slightly caramelized edges. They’re tossed with olive oil, chili powder, ground cumin, smoked paprika, garlic powder, onion powder, oregano, salt, and black pepper to create that classic fajita seasoning. Finish everything with a squeeze of fresh lime juice and a sprinkle of fresh cilantro for a bright, fresh finish.
How to Make Sheet Pan Fajita Vegetables
Start by slicing the bell peppers and red onion into thin strips so they roast evenly. Add them to a large sheet pan, drizzle with olive oil, and sprinkle over the chili powder, cumin, smoked paprika, garlic powder, onion powder, oregano, salt, and black pepper. Toss everything together until the vegetables are evenly coated, then spread them into a single layer. Roast in a 425°F (220°C) oven for 20-25 minutes, giving everything a quick toss halfway through, until the vegetables are tender with lightly caramelized edges. Finish with a squeeze of fresh lime juice and a sprinkle of fresh cilantro, then serve them however you like in tacos, burritos, rice bowls, salads, or alongside your favorite Mexican-inspired meals.
Expert Tips
- Slice the vegetables into similar-sized strips so they cook evenly.
- Spread everything into a single layer on the sheet pan. Overcrowding can cause the vegetables to steam instead of roast.
- For the best caramelization, use a large baking sheet with enough space between the vegetables.
- Give the vegetables a quick toss halfway through roasting to help them brown evenly.
- Add the fresh lime juice and cilantro after roasting to keep their flavors bright and fresh.
- If you like a little heat, sprinkle in some cayenne pepper or red pepper flakes before roasting.
Variations
One of the best things about these Sheet Pan Fajita Vegetables is how easy they are to customize. Add sliced mushrooms, zucchini, or sweet potatoes for extra veggies, or toss in some drained black beans or chickpeas to make the dish more filling. You can also switch up the seasoning with a little chipotle powder for smoky heat or finish everything with crumbled cotija, feta, or your favorite shredded cheese. However you serve them, these roasted fajita vegetables are an easy way to add bold flavor to tacos, burritos, rice bowls, salads, or quesadillas.
Storage Tips
These Sheet Pan Fajita Vegetables are perfect for meal prep since they store and reheat really well. Let the vegetables cool completely before transferring them to an airtight container and refrigerate for up to 4 days. When you’re ready to enjoy them, reheat them in a skillet, oven, or air fryer until warmed through. While the microwave works too, reheating in the oven or skillet helps bring back some of those delicious roasted edges.
