Imagine biting through a shattering, spice-fragrant crust of toasted walnuts, sesame seeds, and hemp hearts into soft, almost creamy eggplant — then dragging it all through a cloud of tangy whipped feta spiked with lemon and fresh herbs. These air fryer dukkah-crusted eggplant steaks deliver the kind of bold, layered Mediterranean flavors that make you forget you are eating low-carb. The dukkah — an Egyptian nut-and-seed spice blend — forms a golden, crunchy shell in the air fryer while the eggplant interior practically melts on your tongue. It is one of those dinners that feels genuinely special yet comes together in under 25 minutes.

The macros here are textbook keto. Each generous serving packs roughly 41 grams of fat from walnuts, sesame seeds, hemp hearts, olive oil, feta, and cream cheese, while net carbs stay at just 8 grams. Protein clocks in at 17 grams thanks to the nut-and-seed crust and the dairy-rich whipped feta base. Fat accounts for about 76 percent of the total calories, keeping you firmly in that ketogenic sweet spot.

This recipe is a weeknight hero. The homemade dukkah takes five minutes and can be made in bulk for the week, and the air fryer does all the heavy lifting with zero deep-frying mess. Serve the steaks over the whipped feta as an elegant plated dinner, or pile everything onto a bed of greens for a heartier composed salad. Either way, it is on the table faster than delivery could arrive.

Ingredients (serves 2)

For the dukkah crust:

  • 1/4 cup (30g) walnut halves, finely chopped
  • 2 tablespoons (18g) raw sesame seeds
  • 2 tablespoons (20g) hemp hearts
  • 1/4 cup (28g) almond flour
  • 1 teaspoon ground cumin
  • 1 teaspoon ground coriander
  • 1/2 teaspoon smoked paprika
  • 1/2 teaspoon flaky sea salt
  • 1/4 teaspoon freshly ground black pepper

For the eggplant steaks:

  • 1 medium Italian eggplant, about 12 oz (340g)
  • 1 large egg
  • 1 tablespoon (15ml) extra-virgin olive oil
  • Olive oil spray for the air fryer basket

For the whipped feta:

  • 3 oz (85g) feta cheese, crumbled
  • 2 oz (55g) cream cheese, softened
  • 1 tablespoon (15ml) extra-virgin olive oil
  • 1 tablespoon (15ml) fresh lemon juice
  • 1 small clove garlic, minced
  • Pinch of salt, to taste

For serving:

  • 1 tablespoon (9g) toasted sesame seeds
  • Fresh mint or dill, roughly torn
  • Pinch of Aleppo pepper or red pepper flakes
  • Lemon wedges

Instructions

  1. Make the dukkah crust. In a dry skillet over medium heat, toast the chopped walnuts and sesame seeds for 2 to 3 minutes, stirring frequently, until fragrant and just turning golden. Transfer to a wide shallow bowl and let cool for one minute. Add the hemp hearts, almond flour, cumin, coriander, smoked paprika, salt, and pepper. Toss to combine evenly.

  2. Slice the eggplant. Trim the ends off the eggplant and cut it crosswise into rounds about 3/4 inch (2cm) thick. You should get 5 to 6 substantial steaks. Pat each round dry with a paper towel — this is critical for a crispy result.

  3. Set up the breading station. In a second shallow bowl, whisk together the egg and olive oil until well combined. Working one at a time, dip each eggplant round into the egg wash, letting excess drip off, then press both sides firmly into the dukkah mixture so a thick, even crust adheres. Set the coated rounds on a plate.

  4. Preheat the air fryer. Set your air fryer to 380°F (193°C) and let it preheat for 2 to 3 minutes. Lightly mist the basket or rack with olive oil spray.

  5. Air fry the eggplant steaks. Arrange the coated rounds in a single layer in the basket — do not overlap them. Work in two batches if your air fryer is smaller than 5 quarts. Lightly mist the tops of the steaks with olive oil spray. Cook for 7 minutes, then carefully flip each round using a thin spatula, mist the second side, and cook for another 5 to 7 minutes until the crust is deep golden brown and the eggplant feels tender when pierced with a knife. The edges should be visibly crispy and pulling away slightly from the flesh.

  6. Make the whipped feta while the eggplant cooks. Combine the crumbled feta, softened cream cheese, olive oil, lemon juice, and garlic in a small food processor or use an immersion blender in a tall cup. Blend for 30 to 45 seconds until very smooth and fluffy, scraping down the sides as needed. Taste and adjust salt — feta varies in saltiness, so go easy at first. If the mixture is too thick, add a teaspoon of water and blend again.

  7. Plate and serve. Spread a generous swoosh of whipped feta across each plate. Shingle the hot dukkah-crusted eggplant steaks over the top. Scatter with toasted sesame seeds, torn fresh mint or dill, and a pinch of Aleppo pepper. Serve immediately with lemon wedges on the side for squeezing over.

Tips & Variations

Make the dukkah in bulk. Double or triple the dukkah crust mixture and store the extra in an airtight jar at room temperature for up to two weeks. It is endlessly versatile — sprinkle it on avocado halves, stir it into yogurt, or use it to crust halloumi or paneer steaks later in the week.

Choose the right eggplant. Italian or Japanese eggplants work best because they have fewer seeds and a creamier texture than large globe eggplants. If you can only find a globe variety, choose a smaller one and salt the slices for 10 minutes before patting dry, which draws out excess moisture and prevents a soggy crust.

Watch your hidden carbs. Commercial dukkah blends sometimes contain added sugars, dried fruit, or wheat-based fillers that spike the carb count. Making your own from scratch, as in this recipe, guarantees clean keto macros and lets you control exactly what goes in. Always check labels if you substitute a store-bought blend.

Add protein to make it even more substantial. For a higher-protein dinner, top each plate with a fried or poached egg, or crumble some extra feta over the finished dish. A 6-minute jammy egg adds roughly 6 grams of protein and 5 grams of fat per egg while keeping carbs near zero — perfect for keto.

Swap the nut to keep it fresh. Pecans, almonds, or even macadamia nuts can replace the walnuts in the dukkah. Each brings a slightly different flavor profile — pecans lean sweeter and more buttery, while macadamias add an almost tropical richness. The sesame seeds and hemp hearts provide the backbone, so the recipe stays cohesive regardless of which nut you use.

Frequently Asked Questions

Is eggplant keto-friendly? It seems like a starchy vegetable.
Eggplant is actually one of the most keto-compatible vegetables available. A full cup of cubed raw eggplant contains only about 2 grams of net carbs, which is lower than many other popular vegetables like bell peppers or tomatoes. It is technically a fruit in the botanical sense, but nutritionally it behaves like a very low-carb vegetable. The flesh is mostly water and fiber, making it an excellent vehicle for carrying rich, fatty flavors like the dukkah crust and whipped feta in this recipe. Just be mindful of breading thickness and any added sauces, which is where hidden carbs tend to creep in.
Can I make this nut-free for someone with allergies?
Yes. Replace the chopped walnuts with an equal amount of extra sesame seeds or sunflower seeds to keep the crust crunchy and flavorful without any tree nuts. You will also need to swap the almond flour for an equal weight of sunflower seed flour or finely ground pumpkin seeds. The texture will be slightly different — a touch grainier — but the air fryer still produces a beautifully golden crust. The fat and carb profile stays very similar with these swaps, so your macros remain solidly keto.
How do I store leftovers, and do they reheat well?
Store the eggplant steaks and whipped feta separately in airtight containers in the refrigerator for up to three days. The whipped feta keeps beautifully and can be served cold or at room temperature. For the eggplant, reheat the steaks in the air fryer at 350°F (175°C) for 3 to 4 minutes to restore their crispiness — microwaving will make the crust soggy, so avoid it if possible. The dukkah coating holds up surprisingly well overnight, though the crust will never be quite as shatteringly crisp as the first time around.
How can I adapt this for a dairy-free or vegan keto diet?
For the whipped feta, blend together half a ripe avocado with 2 tablespoons of tahini, a tablespoon of lemon juice, a small garlic clove, and a pinch of salt. This creates a rich, creamy base with a tangy edge that mimics the feta version surprisingly well. Replace the egg wash with a flax egg — one tablespoon of ground flaxseed whisked with three tablespoons of water and left to gel for five minutes. The dukkah crust itself is already naturally vegan. These swaps keep the dish firmly in keto territory while making it completely plant-based.
My eggplant steaks came out soft in the middle instead of crispy all the way through. What went wrong?
This is actually the intended texture — the inside of the eggplant should be silky and almost custardy while the dukkah crust stays crisp on the outside. If you prefer a firmer bite throughout, slice the rounds thinner, about 1/2 inch (1.3cm) instead of 3/4 inch, and reduce the cook time by 2 to 3 minutes. Also make sure you are patting the eggplant completely dry before dipping into the egg wash, as surface moisture creates steam that softens the crust from within. Finally, avoid overcrowding the air fryer basket — proper airflow is essential for achieving maximum crunch on all sides.
