Fajitas are a great way to get more veggies into the kids, most kids can’t help but love messy finger food and who can blame them. What’s better than building your own fajita? Fajitas have been one of my daughter’s favourite dinners since she was able to hold a taco.

Vegetable fajitas are also a reliable vegetarian dinner option but they can sometimes fall a little short of the flavour side. Not these bad boys, nope, these easy sheet pan veggie fajitas are packed with flavour. The vegetables are roasted in a slightly sweet slightly spicy marinade. No store bought fajita mix either, we always make our own spice mixes. They are so easy to make and if you cook a lot you’ll probably have all the spices you need in your cupboards anyway.

step by step process to making vegetarian fajitas

How to Make Vegetable Fajitas
Start by making that spice mix. We use a mixture of cumin, coriander, ground and dried, paprika, oregano, some hot chilli powder and a pinch of cinnamon. This spice mix can be used for any fajitas or tacos.
Turn that spice mix into a marinade. For this recipe, I’ve added lime juice, maple syrup and olive oil. Give it all a good stir until you have a sauce.
Marinate those veggies, now this is a quick recipe and these veggies are going to be roasted in that marinade so a quick 10 minutes to soak up that sauce is all you need here. Pour the marinade over the veggies and make sure everything is covered in it. You may need to use your hands here.
Roast the veggies, the vegetables will need about 20 minutes, and I always take them out halfway through cooking and give them a good stir and flip them over so they all get a good amount of sauce on them. Once the veggies are cooked all you need to do is build your fajita. We like some sour cream with these along with lime wedges, some avocado and grated mature cheddar. I like to add some pickled jalapenos to mine, I like the extra heat!

What to Serve with Vegetable Fajitas
These fajitas are perfect on their own but if we want to make it more of a vegetarian fajita party we add some guacamole and salsa. A spicy Mexican bean salad is great as a side too and if we’re really hungry some loaded nachos to kick the party off is always a good idea.

Can I make this ahead?
This is really quick and easy to make and to be honest tastes best when made fresh. However, you can make the marinade a day before if you want. And you could marinade those veggies a few hours beforehand if you wish.

This recipe makes enough to serve 4 people, we used 2 medium tortillas per person. This recipe is easy to scale up, please see the scale tool in the recipe card.
If you want to make these quicker then skip marinating the vegetables. I have made these both ways and they are absolutely fine without the 10-minutes to marinate.
Make them Vegan, these vegetable fajitas are vegan I haven’t listed them as such as I have added cheese and sour cream to the final dish.
Make them Gluten Free, use your favourite gluten-free tortillas.
Storing these vegetable fajitas, these are really best made and eaten fresh however if you have any leftover vegetables then you can keep them in the fridge for a day or two. I don’t recommend freezing the vegetables as they will get soggy once defrosted.
Reheating, add any leftover cooked vegetables to a skillet and cook with a little oil until they are piping hot.
