Magic Mushroom Frittata

This vibrant mushroom frittata is a sophisticated take on a vegetarian classic, offering a wonderful depth of flavour and a unique nutritional boost. By using shiitake mushrooms for their earthy richness and pairing them with robust Tuscan kale, this dish provides a satisfying texture that works beautifully for brunch, lunch, or a light evening meal. The addition of fresh tarragon and thyme ensures every bite is aromatic and fragrant.

What sets this recipe apart is the inclusion of plain kefir and farmer cheese, which provide a delicate tang and a light, airy consistency to the eggs. High in protein and packed with savoury notes, it is an excellent choice for those seeking a healthy, homemade meal. Serve it warm from the oven or at room temperature with a crisp green salad for a balanced, seasonal feast.

Ingredients for Magic Mushroom Frittata

  • 240ml plus 2 tablespoons extra virgin olive oil

  • 240ml sliced shiitake mushrooms

  • Maldon sea salt

  • 1/2 cup firmly packed lacinato (Tuscan) kale, plus a few extra leaves for garnish (optional)

  • 1 clove garlic, sliced

  • 40g sliced red onion

  • 6 large brown eggs

  • 180ml organic plain whole-milk kefir

  • Kefir Farmer Cheese, crumbled

  • 1 teaspoon chopped fresh tarragon

  • 1 teaspoon chopped fresh flat-leaf parsley

  • 1 teaspoon chopped fresh thyme

In a medium sauté pan, heat 120ml the olive oil over medium- high heat until slightly shimmering. Add the shiitake slices, spreading them evenly around the pan. Now leave those mushrooms alone! Do not touch them until that sizzling sound quiets down; this will help them develop a beautiful golden brown caramelization on one side. Once that happens, give the pan a stir with a wooden spoon, loosening all the mushrooms. Cook for a few minutes more and season with a pinch of sea salt. (Do not salt until the end, as salting draws out moisture in the pan and prevents caramelization.) Remove the mushrooms from the pan and set aside in a bowl or plate to cool.

Trim the kale off of its stem and cut into thin strips. In a medium sauté pan, heat 2 tablespoons of the olive oil over medium-high heat. Add the garlic and red onion. When the garlic is slightly browned, add the kale and sauté until soft, 3 to 4 minutes. (Add a small amount of water if the kale begins to stick or turn too brown.) Season with a pinch of sea salt and set aside with the mushrooms.

Preheat the oven to 163°C. Place a large shallow nonstick ovenproof dish in the oven.

In a bowl, whip the eggs with a whisk until fully beaten and slightly fluffy. Stir in the kefir, 120ml the olive oil, the farmer cheese, cooked mushrooms, sautéed kale, chopped herbs, and 2 pinches of salt. Pour the entire mixture into the heated ovenproof dish, and bake until slightly browned on top and a knife stuck in the centre comes out clean, about 30 minutes. (If opting for the kale garnish, add the leaves after 15 minutes of cooking.)
