Picture a thick, fluffy egg bake packed with salty feta crumbles, wilted spinach, and pockets of sweet sun-dried tomato, all hiding beneath a shatteringly golden halloumi crust that crackles the moment you cut through it. That is what happens when you combine the best of Greek taverna flavors with the focused heat of an air fryer. The circulating hot air turns ordinary halloumi slices into a bronzed, crispy-edged crown while the egg mixture below sets into a rich, custard-like interior that holds its shape on the plate. Finished with a quick olive-caper relish that cuts through every ounce of richness, this is the kind of weeknight dinner that makes you forget you are eating keto.

Every generous wedge delivers 47 grams of fat and 32 grams of protein while keeping net carbs down to just 6 grams per serving. Halloumi and feta do the heavy lifting on both the fat and protein fronts, while the eggs contribute a silky, buttery richness that binds everything together into one cohesive bake. The fat-to-calorie ratio lands right at 73 percent, the kind of macro split that supports steady ketosis without any complicated tracking or calorie counting.

Prep takes ten minutes, the air fryer handles the rest in under twenty, and your entire dinner lands on the table in about half an hour with virtually zero hands-on effort after you slide the pan in. There is no flipping, no babysitting, and cleanup is a single pan plus one small bowl for the relish. Pair it with a crisp cucumber-tomato salad dressed in olive oil and a squeeze of lemon, and you have a complete Mediterranean spread that feels special enough for company but simple enough for any Tuesday night.

Ingredients (serves 2)

For the egg bake:

  • 6 large eggs
  • 4 oz (115g) halloumi cheese, sliced into 1/4-inch (6mm) rounds
  • 1 oz (28g) feta cheese, crumbled
  • 1 cup (30g) baby spinach, roughly chopped
  • 2 tablespoons (15g) oil-packed sun-dried tomatoes, drained and chopped
  • 1 tablespoon (15ml) extra virgin olive oil
  • 1 clove garlic, minced
  • 1/2 teaspoon dried oregano
  • 1/4 teaspoon freshly ground black pepper

For the olive relish:

  • 8 kalamata olives, pitted and roughly chopped
  • 1 tablespoon (9g) capers, drained and roughly chopped
  • 1 tablespoon (15ml) extra virgin olive oil
  • 1 teaspoon fresh lemon juice
  • 1 tablespoon fresh dill, finely chopped
  • 1 tablespoon fresh flat-leaf parsley, finely chopped
  • Pinch of red pepper flakes

Instructions

  1. Preheat your air fryer to 350°F (175°C) for 3 minutes. While it heats, prepare the egg mixture.

  2. Whisk the eggs in a large bowl until fully combined with no streaks of white remaining. Add the crumbled feta, chopped spinach, chopped sun-dried tomatoes, minced garlic, dried oregano, and black pepper. Stir until everything is evenly distributed throughout the eggs. Do not add extra salt here because the feta and halloumi contribute plenty of salinity on their own.

  3. Prepare the pan. Brush a 7-inch (18cm) round air fryer-safe pan or cake pan with the tablespoon of olive oil, making sure to coat the bottom and sides completely. This prevents sticking and gives the base of the bake a lightly golden finish.

  4. Pour the egg mixture into the prepared pan. Give it a gentle shake to level the surface. The mixture should be roughly 1 inch (2.5cm) deep.

  5. Arrange the halloumi slices in a single layer on top of the egg mixture, overlapping slightly if needed to cover most of the surface. Press each slice down gently so it sits half-submerged in the eggs. This ensures the bottom of the halloumi absorbs flavor while the top gets direct air fryer heat for maximum browning.

  6. Air fry at 350°F (175°C) for 15 to 18 minutes. Start checking at 15 minutes. The egg bake is done when the center is set and no longer jiggles, the halloumi is deep golden brown on top, and a toothpick inserted near the center comes out clean. If the halloumi is browning too quickly but the eggs are still not set, tent the pan loosely with a small piece of foil for the remaining few minutes.

  7. Make the olive relish while the bake cooks. In a small bowl, combine the chopped kalamata olives, capers, olive oil, lemon juice, dill, parsley, and red pepper flakes. Stir well and set aside at room temperature so the flavors have time to meld.

  8. Rest the bake for 2 to 3 minutes in the pan after removing it from the air fryer. This brief resting period lets the eggs finish setting from residual heat and makes slicing much cleaner. Run a thin spatula or butter knife around the edges to release any spots that stuck.

  9. Slide the bake onto a cutting board and cut it into wedges. Serve immediately with the olive relish spooned generously over the top. A drizzle of additional olive oil and a scattering of fresh dill finishes it beautifully.

Tips & Variations

Pan size makes all the difference. Most standard air fryers accommodate a 6-to-7-inch round pan comfortably. If your air fryer basket is smaller, divide the mixture between two smaller ramekins or mini cake pans and reduce cook time by 3 to 4 minutes. The key is keeping the egg layer roughly 1 inch thick so the center cooks through without the edges drying out.

Let the bake rest before cutting. It is tempting to dive straight in, but giving the bake a full 2 to 3 minutes in the pan allows the eggs to finish setting from carryover heat. Cutting too early results in a runny, difficult-to-plate center. A brief rest also makes the halloumi crust slightly firmer and more satisfying to slice through.

Check your sun-dried tomatoes for hidden carbs. Oil-packed sun-dried tomatoes generally have fewer carbs per tablespoon than their dry-packed counterparts because the sugars are less concentrated. Still, some brands sneak in added sugar, which can push a seemingly innocent topping into higher-carb territory. Read the label and aim for 3 grams or fewer total carbs per 2-tablespoon serving. If you cannot find a clean brand, swap in a tablespoon of finely chopped roasted red pepper from a jar for a similar sweetness with fewer carbs.

Make the olive relish ahead of time. It keeps in a sealed container in the fridge for up to five days and actually improves as the flavors marry. Use it throughout the week spooned over scrambled eggs, grilled halloumi slices, or roasted zucchini to add instant Mediterranean brightness to any keto meal.

Swap the greens to keep things fresh. Roughly chopped arugula, de-stemmed and finely sliced kale, or Swiss chard all work in place of the baby spinach. Frozen spinach is also perfectly fine in a pinch. Thaw it first and squeeze out as much moisture as possible by wrapping it in a clean kitchen towel and wringing firmly, otherwise the excess water will make the bottom of the bake soggy.

Frequently Asked Questions

Can I make this in a regular oven instead of an air fryer?
Absolutely. Preheat your oven to 375°F (190°C) and use an oven-safe 7-inch round dish, a small cast iron skillet, or individual ramekins. Bake for 22 to 28 minutes, checking at the 22-minute mark. The halloumi will not get quite as crispy as it does in an air fryer because a conventional oven does not circulate air as aggressively around the surface. For extra browning, switch to the broiler for the final 2 to 3 minutes and watch closely so the halloumi does not burn. The macros remain identical regardless of cooking method.
What can I use instead of halloumi cheese?
If halloumi is not available, thick slices of kasseri, provolone, or even firm mozzarella make good substitutes, though they will melt more than halloumi and create a bubbly cheese layer rather than distinct crispy slices. For a closer texture match, try bread cheese (also sold as juustoleipa), which holds its shape under high heat the way halloumi does. Paneer is another option that will not melt, though it browns differently and tastes milder. Adjust salt slightly since most substitutes are less salty than halloumi.
How do I store leftovers and reheat them?
Wrap individual slices tightly in plastic wrap or store in an airtight container in the fridge for up to three days. To reheat, place a slice back in the air fryer at 325°F (165°C) for 4 to 5 minutes until warmed through and the halloumi re-crisps on top. Microwaving works in a pinch but the halloumi loses its crunch and turns slightly rubbery. The olive relish stores separately for up to five days. This bake does not freeze well because the egg texture becomes watery and grainy after thawing.
Can I adapt this recipe for dairy-free or vegan keto?
Dairy-free keto is tricky here since both the halloumi crust and feta filling are central to the dish. For the feta component, you can use a dairy-free feta crumble made from coconut oil and tapioca, but check the carb count carefully since many vegan cheese alternatives are higher in carbs than real cheese. For the halloumi crust, try thick slices of extra-firm tofu pressed dry and brushed with olive oil, which will crisp up in the air fryer though with a different flavor profile. For a fully vegan version, replace the eggs with a seasoned silken tofu mixture blended until smooth, adding a tablespoon of nutritional yeast for depth. Keep in mind the macro profile will shift significantly with these swaps.
My egg bake puffs up in the air fryer and then deflates. Is that a problem?
Not at all. Some puffing is normal and even desirable because it means the eggs are trapping steam and air as they set, creating a lighter, more soufflé-like texture. The bake will settle slightly as it cools during the resting period, which is completely expected. If it puffs so dramatically that it pushes the halloumi off-center, your air fryer may be running a bit hot. Try reducing the temperature by 10°F and adding a minute or two to the cook time. Pressing the halloumi slices gently into the egg mixture before cooking also helps anchor them in place as the bake rises.
