    These vegetable fajitas are quick and easy to make, and it's all roasted in the oven to make things a little more simple. A great way to get more vegetables in your diet, this vegetarian Mexican dish is packed full of flavour from our easy homemade Fajita seasoning and easy to adapt with your favourite vegetables. Cooked in just 30 minutes too!

    Fajitas are usually cooked on a griddle pan, but we have roasted them in the oven as we find it really brings out the flavour of the vegetables, especially the sweetness of the peppers. It also means it can be mixed up and put in the oven, and there is no need to stand over the hob stirring the pan.

    These vegetable fajitas are hearty and satisfying and a great way to eat more meat free meals. Kids will love building up their own fajitas with their favourite toppings too. Bold and vibrant, with lots of flavour and crunch. What's not to love!

    Why you will love it

    • Quick and easy - These take just 5 minutes to prepare and then just 30 minutes in to oven to get the vegetables roasted.
    • Minimal ingredients - Just 6 ingredients go into making the fajitas mixture and then you have lots of options for the toppings. More on that below!
    • Adaptable - The great thing about these is that they are so easy to adapt. A great way to use up whatever you have in the fridge.
    • Can be made in advance - You can make up the vegetables in advance and then keep them in the fridge until you are ready to cook them.

    Ingredients needed

    All the ingredients needed for this recipe with text overlay labels.
    • Bell peppers - You can use any ripe bell peppers that you like. Red, orange, yellow, green - they will all work. We prefer red and orange as they are the sweetest and they are really good when roasted.
    • Onion - You can use a brown or red onion here and they will both caramelise really well when roasted.
    • Mushrooms - We used large cap/portobello mushrooms here and it gives the vegetable fajitas a real meaty texture. Any mushrooms will work though.
    • Fajita seasoning - We used our Homemade Fajita Seasoning because it's so cheap to make and you can control just how spicy or mild it is. You can use a store bought seasoning if you prefer.
    • Oil - Olive oil or vegetable oil will be fine.
    • Chipotle paste -  If you want to add some extra flavour and spice to your vegetable fajitas, then a little bit of chipotle paste mixed into the vegetables will do exactly that. It adds a lovely smokiness too.

    A full ingredients list with measurements is in the recipe card below.

    How to make vegetable fajitas - Step by step

    One: Preheat your oven to 200°C/400°F/Gas 6. Put the sliced peppers, mushrooms and onion into a large baking dish. Add the oil, chipotle paste and seasoning. Mix well so that everything is coated.

    Three shot collage of sliced vegetables in a baking dish, oil and seasoning added, then all mixed together.

    Two: Cook for 30 minutes, stirring halfway.

    All the vegetables cooed in the baking dish.

    Three: Build your fajita by spreading a tortilla wrap with sour cream, adding lettuce, avocado and the vegetables. Top with salsa, feta cheese and a squeeze of lime juice.

    What vegetables to use

    The great thing about these is that they are so easy to adapt. We have used onion, bell peppers and portobello mushrooms. However there are lots of options when it comes to vegetables. Here are some others that work well:

    • Courgette
    • Broccoli
    • Cauliflower
    • Baby corn
    • Tomatoes
    • Aubergine
    • Asparagus
    • Sweetcorn

    Healthy tip

    If you want to add some extra protein to these vegetable fajitas but still keep them vegetarian, then why not add some beans? Cooked black beans or pinto beans work well, or you could even add some roasted chickpeas.

    What to serve with vegetable fajitas

    Once you have got our flavour packed vegetable fajita vegetables, you need something of them to all lay in. Use a good quality flour tortilla. You can use large or small, depending on how big a portion you want. Why not try our Homemade Wholemeal Tortilla Wraps. You don't have to serve them in a tortilla though. The vegetable mixture is delicious on top of rice or quinoa or even used to make nachos with.

    Now, let's talk toppings!

    Avocado: We kept it simple with some slices of avocado, but you could use smashed avocado our go all out and make our Best Ever Guacamole Recipe.

    Salsa: We made a quick and easy fresh salsa with some diced cherry tomatoes, coriander and lime juice. But you could make our Pico De Galo or Restaurant Style Salsa.

    Sour cream: We think this is a must on fajitas, but if you want to keep it vegan then you can swap it for cashew cream. Want a lighter version? Use some fat free Greek yogurt.

    Cheese: We have added a little feta on top for some added creaminess, but it really doesn't need it. Leave it out if you want to keep these vegan. You can add grated mature cheddar, queso fresco or cotija cheese.

    Lettuce: Add some shredded little gem or iceberg for added crunch.

    If you are serving these up as a big meal for a few people, then you might want some sides to go with it all. Why not try our Cilantro and Lime Rice or Baked Tortilla Chips.

    Storage

    Store: These are best eaten straight away. However, if you do have leftovers then you can keep them in an air tight container in the fridge for up to 2 days.

    Freeze: We wouldn't recommend freezing these, because the vegetables get soggy when they are defrosted.

    Reheat: You can reheat these in a frying pan. It will take about 5 minutes coming cold out of the fridge.

    Frequently Asked Questions

    How can you bulk out fajitas?

    If you wanted to bulk these out and make them more filling, then some cooked black beans or lentils would work well.

    How many calories in vegetable fajitas?

    There are 233 calories per portion, but that doesn't include any of the toppings.

    How do you stop fajitas getting dry?

    Cooking them in the oven helps to keep everything nice and moist. Also, make sure you use enough oil.

    What is the difference between a fajita and taco?

    Here is where we tell you that technically this isn't a real fajita. Fajitas are usually served in larger wraps, whereas tacos are served in smaller taco sized tortillas. We have served these in smaller tortillas for smaller serving sizes. Also, fajitas are usually always grilled, but we have done ours in the oven to keep it nice and easy. With fajitas, the vegetables are always cooked, however with tacos you usually have raw veggies served on top. Fajita and taco seasonings are technically different, but they pretty much the same herbs and spices.

    Do you need to marinate vegetables for fajitas?

    If you want to give these a little more flavour, then you can let everything marinade for 10-15 minutes. However, you don't have to do this.

    Can you fry vegetable fajitas?

    Yes, you can cook these in a frying pan, but we find they tend to be a bit dry. They will take about 10 minutes in a frying pan though, so it's a good option if you want a quicker meal.

    Can I add chicken?

    Yes, you can add chicken. It's a great way to use up leftovers from roast chicken.

    Are vegetable fajitas vegan?

    This recipe isn't vegan because of the sour cream and feta, but you could leave those out or use alternatives if you wanted to keep these vegan.

    Are vegetable fajitas gluten free?

    If you use gluten free tortillas and make sure that there is no cross contamination, then these can be gluten free.

    Can you make vegetable fajitas in advance?

    Yes, you can add the oil and seasoning to the vegetables and then keep it in the fridge until you are ready to cook it. It might need a little longer in the oven if it is cold from the oven.

    Extra tips

    • Use your hands to mix everything together, so the seasoning gets on every part of the vegetables.
    • Add a squeeze of fresh lime over the fajitas before serving. This will add some freshness and really bring all the ingredients to life.
    • Cut all the vegetables into long strips, so they will run the length of the tortilla when they are added to it. When they are cut in to strips, they will have more surface area that will touch the baking dish too, helping them to get nice and crispy. Thin strips cook faster too.
    • Spoon the fajitas out of the dish and on to the tortilla using a slotted spoon. Although most of the juice should have cooked away, there will be some left in the dish and you don't want all of that transferring over to the tortilla. That will make it very messy to eat.
