Marinated Mushroom, Tomato, and Spring onion Skewers

These marinated mushroom, tomato, and spring onion skewers are a vibrant addition to any outdoor gathering. This vegan dish relies on a simple yet punchy marinade of extra-virgin olive oil, red wine vinegar, and fresh woody herbs like thyme and rosemary to bring out the natural sweetness of the cherry tomatoes and the earthy depth of the mushrooms. The gentle heat of chilli flakes adds a subtle warmth that complements the charred, smoky finish from the grill.

Ideal for a summer barbecue or a rustic campfire supper, these skewers are incredibly versatile and can be prepared up to a day in advance. Soaking the vegetables in the savoury dressing ensures they remain juicy while they caramelise over the flames. Serve them as a light main with flatbreads and a cooling dip, or as a side dish alongside other seasonal grilled vegetables for a complete plant-based feast.

  • 120ml extra-virgin olive oil

  • 60ml red wine or Sherry vinegar

  • 3 tablespoons chopped fresh thyme and/or rosemary leaves

  • Large pinch of crushed red pepper flakes

  • 1 teaspoon kosher salt, plus more to taste

  • 1/2 teaspoons freshly ground black pepper, plus more to taste

  • 6 spring onions, cut crosswise into 2-inch pieces

  • 4–6 long wooden or metal skewers, or 4–6 long live branches whittled down to sharpened sticks

How to make Marinated Mushroom, Tomato, and Spring onion Skewers

Whisk garlic, oil, vinegar, thyme, red pepper flakes, 1 teaspoon salt, and 1/2 teaspoons black pepper in a medium bowl. Transfer mixture to a resealable container or plastic bag and add spring onions, tomatoes, and mushrooms. Marinate until ready to cook, at least 15 minutes.

If using wooden skewers or branches, soak them in water at least 10 minutes. Skewer spring onions, tomatoes, and mushrooms, dividing evenly and leaving about 4 inches of empty skewer at the bottom. Reserve leftover marinade.

Prepare a campfire for medium heat. When it's ablaze, carefully place skewers vertically in the ground around the fire; they should be close enough to the flames that the ingredients begin sizzling within a few seconds. Cook, rotating skewers occasionally, until spring onions, tomatoes, and mushrooms are caramelized or charred in spots and mushrooms are tender, 10–15 minutes.

Transfer skewers to plates, season with salt and black pepper, drizzle with reserved marinade, and serve.

Vegetables can be marinated and chilled up to 1 day in advance.
