Prep the eggplant: Wash and dry the eggplant. Trim the stem. Cut into 1/2-inch slices or 1-inch cubes.
Keep the pieces uniform so they cook evenly.
Salt and rest: Place the eggplant in a colander and sprinkle with 1 teaspoon kosher salt. Toss and let it sit for 15–20 minutes. This helps draw out excess moisture and any bitterness.
Pat dry: Rinse briefly to remove excess salt, then pat the pieces very dry with paper towels.
Removing moisture is key for crisp edges.
Season: In a large bowl, toss eggplant with olive oil, garlic powder, smoked paprika, oregano, 1/4 to 1/2 teaspoon kosher salt (to taste), and black pepper. The coating should be light and even, not wet.
Preheat the air fryer: Set it to 390°F (200°C) for 3–5 minutes. A hot basket helps prevent sticking and promotes better browning.
Arrange in the basket: Lightly spray the basket if sticking is an issue.
Spread the eggplant in a single layer with a little space between pieces. Do not overcrowd; cook in batches if needed.
Air fry: Cook for 12–15 minutes, shaking the basket or flipping halfway. You’re looking for browned, crisp edges and a tender center. Thicker pieces may need an extra 2–3 minutes.
Finish and serve: Transfer to a plate and brighten with a squeeze of lemon, a sprinkle of parsley, or a dusting of Parmesan.
Serve hot as a snack, side, or pile onto grains, salads, or pasta.
