We regularly #TacoTuesday on our homestead, but I thought I would switch it up and create some easy veggie fajitas instead for something a little extra.  These one pan fajitas are so simple to make – chopped veggies, toss with spices,  and roast.

Pile ’em on a tortilla or wrap of choice,  pour yourself a margarita and enjoy. A fantastic lighter whole30 fajitas recipe that is roasted in the oven to perfection.

I have been super obsessed with sheet pan meals lately – I love the concept of letting the oven do the work and having very little to clean up once dinner is done.  These sheet pan fajitas make perfectly roasted veggies that you can top with lime avocado crema, fresh chopped onions, or whatever you’d like.

What’s In These One Pan Vegetable Fajitas?

Be sure to visit the recipe card below for full ingredient amounts and recipe instructions!

  • Onion
  • Sweet Potatoes
  • Bell Pepper
  • Avocados
  • Zucchini
  • Portobello Mushrooms
  • Chili Powder: for a really nice flavor in these veggies – the chili powder isn’t spicy but will give you a rich and bright flavor.
  • Smoked Paprika: give an additional depth of flavor to the fajitas.
  • Oregano: a spice I always put in my chili, tacos, or fajitas!  This dried oregano has a bright and earthy flavor, and goes so well with the roasted vegetables.
  • Adobo Seasoning: a really fantastic blend of salt, pepper, garlic, and spice! I like to get one that doesn’t have a lot of salt it in, so I can control the amount of salt going into the dish.
  • Extra virgin olive oil
