Ingredients You’ll Need
What’s marvelous about building a Halloumi Burger (with Smoky Red Pepper Aioli) is that every ingredient truly shines and plays an important role. The elements are simple and straightforward, but together—they add up to something unforgettable!
- Halloumi Cheese: This semi-firm cheese from Cyprus is famous for its high melting point, so it gets beautifully golden on the outside while staying indulgently chewy.
- Burger Buns: Choose soft, sturdy buns that will hold all those toppings without falling apart—brioche or potato buns are both dreamy options!
- Red Onion: Sliced and grilled, red onion adds natural sweetness and a gentle crunch that balances the creaminess of the cheese.
- Lettuce: Fresh, crisp leaves like romaine or butter lettuce bring cool, verdant crunch and a pop of color.
- Tomato Slices: Juicy, ripe tomatoes provide freshness and a subtle acidity that works wonders in a burger.
- Extra Virgin Olive Oil: This is essential for both grilling the onions (for softening and flavor) and ensuring the halloumi develops that signature crust.
- Whole Egg Mayonnaise: Forms the creamy base of the smoky aioli—choose a good-quality mayo for the best flavor.
- Marinated Roasted Red Peppers: These give the aioli its signature smoky-sweet vibe and gorgeous color.
- Garlic Clove: A little raw garlic goes a long way—add a second clove if you love bold, pungent aioli!
- Red Pepper Flakes: A pinch or more for just the right amount of tingle; adjust to suit your spice tolerance.
- Lemon Juice: A quick squeeze brings brightness and lifts all the flavors in the aioli.
- Salt: Just a dash, both for seasoning the aioli and enhancing the onion’s flavor.

The magic of this Halloumi Burger (with Smoky Red Pepper Aioli) is how endlessly it can be customized—so don’t be afraid to make it your own! Whether you’re craving more spice, want to play with textures, or need a gluten-free bun, the possibilities are deliciously flexible.
- Gluten-Free Version: Swap in your favorite gluten-free burger buns or even lettuce wraps for a lighter, gluten-free meal.
- Vegan Twist: Use vegan halloumi-style cheese and plant-based mayo to keep the indulgence while making it totally dairy- and egg-free.
- Extra Veggies: Stack on grilled zucchini, eggplant, or avocado slices for extra color and nutrients.
- Spice it Up: Add a few jalapeño rings or a pinch of smoked paprika to the aioli for even more smoky heat.
How to Make Halloumi Burger (with Smoky Red Pepper Aioli)
Step 1: Blend the Smoky Red Pepper Aioli
Start by making the flavor-packed aioli: toss the mayo, drained roasted red peppers, garlic, red pepper flakes, and a dash of salt into a blender or a tall jar if using an immersion blender. Blend everything until creamy and smooth, then transfer to a bowl and squeeze in fresh lemon juice for an extra zing. Taste and adjust seasoning as you like—it should be creamy, garlicky, and slightly smoky.
Step 2: Prep and Grill the Halloumi
Slice your block of halloumi cheese into two thick slabs, then rub each with a bit of olive oil so they won’t stick to the pan. Heat a grill pan or skillet to medium, drizzle a little oil on one half, and add the sliced red onions with a pinch of salt. For quicker softening, add a splash of water—the onions will turn silky and sweet as they cook.
Step 3: Grill the Cheese and Toast the Buns
Once the onions are nearly caramelized, slide them aside and add more oil to the pan. Place the halloumi slices down and let them cook untouched for 2–3 minutes until they form a beautiful golden crust and signature grill marks. Flip to brown the other side, and while that’s happening, split your burger buns and toast them cut side down right in the pan for maximum flavor.
Step 4: Assemble and Serve
Now for the most rewarding part—assembly! Generously spread red pepper aioli on the bottom buns. Layer in the crisp lettuce, juicy tomato slices sprinkled with a punch of salt, and a tumble of those sweet grilled onions. Top with the sizzling, golden halloumi, slather the top bun with a touch more aioli, crown the burger, and savor every bite. Your Halloumi Burger (with Smoky Red Pepper Aioli) is ready to steal the show!
Pro Tips for Making Halloumi Burger (with Smoky Red Pepper Aioli)
- Grill Pan Magic: Let the halloumi sit undisturbed so it crisps and develops those irresistible golden grill lines.
- The Softer the Onion, the Better: Cooking red onions with a touch of water not only prevents sticking but also brings out their natural sweetness—don’t rush this step!
- Bold Aioli, Your Way: Taste the aioli before assembling—add more garlic for a punchier spread or a squeeze of lemon for brightness until it’s your perfect blend.
- Assembly Order Matters: Add lettuce first to keep the bun from getting soggy and finish with a swipe of aioli on both bun halves for maximum sauciness in every bite.
How to Serve Halloumi Burger (with Smoky Red Pepper Aioli)
Garnishes
For a truly next-level Halloumi Burger (with Smoky Red Pepper Aioli), add a generous handful of microgreens, arugula, or cilantro just before serving. A sprinkle of cracked black pepper or extra chili flakes right on top also adds a beautiful visual and flavor pop. If you’re feeling extra, a pickle spear or lightly pickled onions make a bright, tangy finishing flourish.
Side Dishes
Pair your burger with a pile of golden sweet potato fries, seasoned wedges, or even a crisp side salad with a zippy vinaigrette. If you want to keep things Mediterranean, offer up a bowl of marinated olives or a platter of grilled veggies to round out the meal. The Halloumi Burger (with Smoky Red Pepper Aioli) also goes brilliantly with simple chips for a picnic-style vibe.
Creative Ways to Present
Bring restaurant flair to your table by serving these burgers deconstructed—with all the toppings and aioli in little bowls so everyone can build their own. For a fun party twist, cut sliders from smaller buns for crowd-pleasing bites. Or build a burger board with extra grilled veggies and sauces, making your Halloumi Burger (with Smoky Red Pepper Aioli) the star of a sharing feast!
Make Ahead and Storage
Storing Leftovers
If you have leftover assembled burgers, store them wrapped or in an airtight container in the fridge for up to 2 days. For best results with texture, keep the aioli and vegetable toppings separate from the grilled halloumi and buns until you’re ready to eat again—the cheese holds up beautifully, but the buns can get a little soft if stored with the sauce.
Freezing
The aioli and fresh veggies don’t freeze well, but the cooked halloumi slices can be frozen on their own. Let them cool, place parchment between slices, and freeze in a container for up to one month. Thaw in the refrigerator and lightly pan-sear to restore that satisfying texture.
Reheating
To bring leftovers back to life, reheat the halloumi in a nonstick skillet over medium heat for a minute or two on each side. Avoid microwaving—it can make the cheese rubbery! Toast the buns again for the best texture, and reassemble with fresh veggies and aioli just before serving.
FAQs
-
Can I make the smoky red pepper aioli in advance?
Absolutely! The aioli actually tastes even better after a few hours in the fridge. Make it up to 2 days ahead and store covered—it’s perfect for slathering whenever the burger craving strikes.
-
What’s the best way to prevent halloumi from sticking to the pan?
Be sure to lightly oil both the cheese and your grill pan or skillet before cooking. A hot, nonstick surface and avoiding unnecessary flipping are key for achieving that magical golden crust without sticking.
-
Can I make this Halloumi Burger (with Smoky Red Pepper Aioli) vegan?

-
Is there a way to prepare Halloumi Burger (with Smoky Red Pepper Aioli) ahead for parties?
