Oven Fajitas with Veggies! Making these veggie fajitas in the oven is such a simple meal. Throw everything in together, and dinner is ready in just 30 minutes. Customize them however you like.
These oven fajitas are so incredibly yummy (and easy!) that they’ve become my go-to recipe just about weekly.
I first created these veggie fajitas a few years ago when I was pregnant and didn’t want to spend too much time on my feet and, therefore, in the kitchen.
These oven fajitas are just as delicious as regular fajitas, but with a fraction of the effort! Toss your sliced veggies with oil and seasonings, then roast until tender!
Serve with your favorite toppings and enjoy. See below for tips and more details about making these oven fajitas, or scroll down to the recipe card for the full ingredient list and directions.
Preheat the oven, then prep the veggies. Slice your peppers and onions, then toss with oil and spices, making sure that the veggies are well coated with the seasonings.
Spread in a single layer, place in the oven and roast until very tender, tossing halfway through.
Warm tortillas, then add in the veggie fajitas from the oven and serve with your favorite toppings.
Fajita peppers can easily be the cornerstone of most of my meals. I love them wrapped up in a soft tortilla, sometimes with beans, sometimes with scrambled eggs and hot sauce, and sometimes with crumbled taco tofu.
If you like the flavor of fajitas, then I recommend making a double batch of these vegetables. Serve them first as these oven fajitas, then tuck any leftovers into my fajita enchiladas.
This recipe is really customizable. If you’ve got any protein that you want to serve with, add it to the pan before cooking. I often add a can of black beans for 5-10 minutes before pulling the veggies out of the oven to warm through.
Perhaps the best thing about this recipe is that they were made to feed a crowd. Slice all the vegetables ahead of time, then pop in the oven whenever you are ready. Ta-da. That’s it! Dinner is served.

Can I make ahead and reheat in the oven in the same pan.
Yes, that should work! I would cover in foil as it reheats so the peppers “steam” and not dry out as they are warmed.
Made this last night. It was super easy and pretty yummy, too. We arent chili seasoning fans so we used less of the spices. Still, we liked it so much, we are making it tonight, too! Thanks for making it so easy!
So glad you liked it! Thanks Holly!
What a great idea to do this in the oven! Loved it!
I made this for dinner last night. My husband really liked the flavors. We’ll be making this again!!!
So glad to hear- thanks for the comment!
Alex, I roasted these pepper and onions last night. They smelled great while cooking, and they were fantastic with sour cream, enchilada sauce, greens, a little fish, some beluga lentils, cheese, and of course some cilantro. Wonderful!! They are so easy to make, and so versatile!
Awesome Connie! Glad you liked them!
