Halloumi Burger with Harissa Onions

Halloumi burger featuring classic North African flavours of sumac, harissa & zaatar simple to cook and great from the stove top or BBQ!

Don’t get me started on these harissa onions, they are a stroke of genius and work just as well on a beef burger as they do on this veggie burger.

The Perfect Vegetarian Burger.

This recipe is a bit of a revelation recipe as it is one that made my wife smile greatly! Not that my recipes usually make my wife grimace… Honest!

You see she is less than enthusiastic about halloumi cheese because that squeaky texture is a bit “wrong” apparently. This may not have converted her completely but she does love these!

I personally love the stuff and this recipe leans on similar flavours to my zaatar halloumi cheese recipe. 

If you like plain halloumi you must check out my halloumi pasta salad recipe.

As is often the case with my burger recipes I rely on just a few toppings. Just like my pork and apple burger, Jerk chicken burger or my shredded duck burger, these veggie burgers rely on the principle that less can be more!

These halloumi veggie burgers go big with Berber-inspired flavours. The star of the toppings are some slowly cooked onions in harissa paste which adds a sweet spicy complexity.

The halloumi itself gets a little lemon juice and liberal sprinkling of sumac to contrast the sweet onions.

Sear off a slice of tomato in the pan you sear the halloumi in and add some zaatar. Finally, add a bit of lettuce and toast yer buns and you are off.

Frequently Asked Questions.

Can I make the onions in advance?

Yes, they can be made up to a week in advance, simply store them in an airtight container in the fridge.

What is Harissa?

I love harissa, it is one of my favourite store cupboard ingredients! It is complex paste from Tunisia featuring a host of different peppers, garlic, caraway, cumin and coriander.

I add it to obvious dishes like this mixed vegetable tagine or these harissa chicken thighs but also surprising dishes like my carrot and lentil soup.

So don’t worry just type harissa into my search function at the top of the page and you’ll find plenty to use up and left over.

Can I cook this on the BBQ?

Oh gosh yes! A grilled halloumi burger is superb, simply grill over a direct heat for 90 seconds to two minutes per side.

Make sure you season the grill rack well to prevent sticking.

Can I cook the halloumi patties in the air fryer?

Again yes, they work really well. Spray the basket and drop them in for 4-5 minutes at 200°C or 400°F.

Serving Suggestions.

I have a bit of a rep for getting creative with burgers!

Everything from Indian Lamb Burgers to venison burgers make an appearance here, but my choice of sides is usually “less adventurous”.

I almost always have some sort of potato side with my burger, this is no different.

Some potato wedges seasoned with sumac to follow through the North African trend are my usual choice for these.

But they would also work well with these sweet potato fries especially if you added a bit of zaatar.
