How to Make Vegetarian Gyros

Prep Mushrooms

Start by slicing the stems of the king oyster mushrooms into long strips, about ¼–½ inch thick. This helps them cook evenly and maintain their structure.

Marinate

In a mixing bowl, whisk together olive oil, lemon juice, minced garlic, dried oregano, salt, and pepper. Add the mushroom slices and toss to coat. Let the mixture sit for 10–15 minutes. The mix may feel dry at first, but that’s normal.

Cook

Roast the mushrooms on a lined baking sheet at 425°F (220°C) for 12–15 minutes, flipping once, until golden brown and tender. Alternatively, you can pan-sear them in a hot skillet with a splash of oil for 4–5 minutes per side.

Assemble Gyros

Warm the pita bread and layer it with the cooked mushrooms, sliced cucumber, tomato, red onion, and lettuce. Top generously with tzatziki sauce for a creamy finish.

Serve

Wrap the assembled gyros in parchment paper or foil for that authentic Greek street food experience. Enjoy immediately for the best flavor and texture.

Variations

• Spicy vegetarian gyro – Add chili flakes or smoked paprika to the marinade for a kick.
• Gluten-free – Swap pita bread for gluten-free flatbread or lettuce wraps.
• Extra protein – Add grilled halloumi, feta, or crispy chickpeas for a heartier meal.

Tips from Home Cooks

• Slice mushrooms evenly for even cooking.
• For crisp edges, avoid crowding the roasting pan.
• Warm pita in a dry skillet or over an open flame for extra flavor.
• Leftover mushrooms can be tossed into salads, grain bowls, or pasta dishes.
