These roasted mushrooms with spicy breadcrumbs offer a wonderful contrast of textures, combining earthy, tender fungi with a fiery, herbaceous crunch. By using a variety of mushrooms such as chestnut, oyster, and portobello, you create a complex depth of flavour that is heightened by the aromatic garlic and golden butter. The addition of fresh thyme and red pepper flakes to the breadcrumb topping provides a sophisticated heat that perfectly cuts through the richness of the roast.
This versatile vegetarian dish works beautifully as an elegant starter for a dinner party or as a substantial side alongside a Sunday roast. It is a quick and healthy way to elevate simple cupboard staples into something truly special. For the best results, use fresh breadcrumbs to ensure a light, crisp finish that stays crunchy when served over the succulent, garlicky mushrooms.

Ingredients for Roasted Mushrooms with Spicy Breadcrumbs
350g mixed mushrooms (such as cremini, white button, portabella, king trumpet, and oyster)
3 tablespoons extra-virgin olive oil
1 garlic clove, finely chopped
2 tablespoons unsalted butter, cut into tablespoon pieces
110g coarse fresh breadcrumbs (from 2 slices white bread)
1 tablespoon fresh thyme leaves, chopped
1/4 to 1/2 teaspoons hot red pepper flakes
1 tablespoon chopped fresh parsley
How to make Roasted Mushrooms with Spicy Breadcrumbs
Back to contentsPreheat oven to 232°C with rack in middle.
For white button or cremini mushrooms, halve lengthwise. For larger mushrooms such as portabella or king trumpets, cut lengthwise into 1/2-inch slices. For oyster mushrooms, tear into small clumps.
Place mushrooms in a small roasting pan or rimmed sheet pan and toss with 2 tablespoons of the oil, garlic, 1/8 teaspoons salt and 1/8 teaspoons pepper. Top with 1 tablespoon of the butter, cut into pieces, and roast in oven, stirring occasionally, until golden and cooked through, about 15-20 minutes.
Meanwhile, melt remaining 1 tablespoon butter with remaining 1 tablespoon oil in a medium skillet over medium heat. Add breadcrumbs and cook, stirring frequently, 2 minutes. Add thyme and red pepper flakes and cook (there may be some popping), stirring frequently, until breadcrumbs are golden and crisp, about 2 minutes more. Remove from heat and stir in parsley.
To serve, transfer hot roasted mushrooms to a platter and sprinkle with crumbs.
