Halloumi Fajitas
These halloumi fajitas are everything you want from a vegetarian-friendly fajita night - crispy, golden halloumi coated in a smoky chipotle marinade, roasted alongside caramelized peppers and onions, and piled into warm tortillas with all the toppings. They're made on one baking sheet in the oven, so there's barely any washing up. Win-win.

What makes these halloumi fajitas stand out is the chipotle paste. Instead of just dusting the halloumi with dry spice mix like most fajita recipes, you coat the slices in a smoky chipotle and lime marinade that caramelizes beautifully in the oven. The edges get crispy and slightly charred while the inside stays soft and squeaky - it's the perfect fajita filling.
If you love fajita-style dinners, try my crispy black bean tacos, bean and cheese burritos, or Mexican black beans. For more halloumi recipes, my hot honey halloumi wraps are a must-try!
Why You'll Love This Recipe
I've tried a lot of vegetarian fajita fillings, and halloumi is a great option. It has a proper meaty bite, it crisps up beautifully in the oven, and it's salty and savory enough to hold its own against all the bold fajita flavors.
The chipotle paste marinade is what takes these from good to incredible - it gives the halloumi a sticky, smoky coating that caramelizes as it roasts. Even the meat-eaters in your life will want seconds!
Serve alongside some refried beans for a full vegetarian feast!
Ingredient Notes
Here are some notes on the key ingredients. The full quantities are in the recipe card at the bottom of this page.
For the Halloumi and Vegetables
- Halloumi: One block, drained, patted dry, and sliced thinly. Patting it dry is important - if there's any moisture on the surface, it will prevent the halloumi from crisping up in the oven. Slice it into thin strips rather than thick slabs for the best crispy-to-soft ratio.
- Chipotle paste: This is what gives the halloumi its smoky, slightly spicy, sticky coating. You can find chipotle paste in most supermarkets (usually in the world foods aisle). If you can't find it, a teaspoon of smoked paprika mixed with a pinch of cayenne and a drizzle of honey is a reasonable substitute, though not quite the same.
- Bell peppers & red onion: Traditional fajita veg, sliced into thin strips. You could also add in some corn, courgette, or sweet potato if you like!
- Seasonings - smoked paprika, cumin, cayenne, oregano: These coat the vegetables and give them that classic fajita flavor. The cayenne adds just a little heat - feel free to adjust the spice level up or down to your preference.
- Lime: A squeeze goes into the halloumi marinade, and the rest is served as wedges at the table. The acidity brightens everything up.
For Serving
- Tortilla wraps: Eight wraps - flour or corn, whatever you prefer. Warm them briefly in the oven, microwave, or a dry pan before serving.
- Dips/Toppings: Serve your halloumi fajitas with your toppings and dips of choice - I love a creamy guacamole and a fresh pico de gallo salsa, but sour cream, hot sauce, crumbled feta, or a mango salsa would all work perfectly with the smoky halloumi!

How to Make Halloumi Fajitas
Step 1: Marinate the Halloumi
Drain the halloumi and pat it thoroughly dry with paper towels. Slice it thinly into strips. Add the halloumi to a bowl with the chipotle paste, a squeeze of lime juice, a tablespoon of olive oil, and a little salt and pepper.
Mix well until every piece is coated in the sticky chipotle marinade, then arrange the slices flat on a large baking sheet.
Step 3: Season the Vegetables
Slice the peppers and red onion into strips and toss them with the smoked paprika, cumin, cayenne, oregano, and the remaining tablespoon of olive oil.
Add them to the baking sheet around the halloumi, arranging everything as flat as possible so it roasts rather than steams.
Step 4: Roast
Bake for 20-25 minutes until the halloumi is crispy on the edges and golden, and the peppers and onions are softened and slightly charred.
Step 5: Serve
Warm your tortilla wraps and serve the halloumi and vegetables straight from the tray. Let everyone build their own fajitas with the guacamole, pico de gallo, sour cream, crumbled feta, and lime wedges.

Expert Tips for the Best Halloumi Fajitas
- Pat the halloumi completely dry: This is the most important step for crispy halloumi. Any surface moisture will prevent it from getting golden and caramelized in the oven.
The first time I tested this halloumi fajitas recipe, I had a lot of liquid in the baking sheet which prevented the halloumi and the vegetables from getting lovely and charred - which is the whole reason we roast them here! - Slice the halloumi thin: Thin slices (about 5mm) give you a much better crispy-to-soft ratio than thick slabs. More surface area means more crispy edges from the chipotle marinade.
- Arrange everything as flat as you can: Try not to pile the vegetables and halloumi on top of each other. They need space and flat contact with the baking sheet to roast and caramelize properly - if your baking sheet is too crowded, use two.
- The chipotle marinade is the secret: A lot of halloumi fajita recipes just dust everything with a dry spice mix, which is nice, but doesn't give the halloumi that extra oomph I find a vegetarian meal really needs.
The chipotle paste gives the halloumi a sticky, smoky coating that caramelizes in the oven - it's what makes this version extra special!
What to Serve with Halloumi Fajitas
Build your fajitas with the toppings listed above, and if you want sides, any of the following would make for an incredible meal!
- Mexican rice or cilantro-lime rice
- Refried beans or my Mexican pinto beans
- Crispy Mexican potatoes for a more substantial meal
- My creamy avocado lime crema
- A simple slaw with lime and cilantro
- Tortilla chips and salsa (I like making a fresh pico de gallo with diced tomatoes, coriander, diced onion, a pinch of salt, and a squeeze of lime) for a full fajita night spread
Storage
- Refrigerator: Store any leftover halloumi and vegetables in an airtight container for up to 3 days. Reheat in the oven at 200°C for 10 minutes to re-crisp the halloumi, or in a hot pan.
- Meal prep: You can slice and marinate the halloumi and prepare the vegetables a few hours ahead. Store in the fridge and roast when ready to eat.
- Freezing: I wouldn't recommend freezing - halloumi changes texture when frozen and defrosted, becoming rubbery rather than squeaky-soft.

FAQs
Absolutely. Fry the marinated halloumi slices in a hot pan for 2-3 minutes each side until golden. Cook the vegetables separately in the same pan. The stovetop method gives you a slightly more charred finish, but takes more hands-on attention than the oven method.
Yes! Paneer has a similar texture and holds its shape well when cooked. It's less salty than halloumi, so you may want to season it a little more generously.
It has a moderate warmth from the chipotle paste and cayenne. The chipotle gives a smoky heat rather than a sharp kick. Reduce the cayenne or use less chipotle paste for a milder version, or add more for extra heat.
This recipe makes enough filling for about 8 fajitas. Serving 4 people, that's 2 each - add a side of rice or beans if you want a bigger meal. Serving 2, you'll get 3-4 each.
Chipotle paste is made from smoked jalapeño peppers. It has a rich, smoky, slightly sweet heat that's quite different from regular chili powder. You can find it in most UK supermarkets in the world foods or Mexican aisle. A little goes a long way.
