These grilled spiced mushrooms are a fantastic vegetarian addition to any outdoor gathering or weekend barbecue. By charring the mushrooms over a medium heat, you develop a deep, earthy flavour that perfectly complements the punchy addition of toasted cumin and coriander seeds. The heat from the freshly grilled mushrooms melts the herb-infused butter instantly, creating a rich, savoury glaze that clings to every surface.
This simple dish is naturally gluten-free and works beautifully as a standalone starter or as a side to accompany grilled halloumi or seasonal salads. Using flat-leaf parsley and a touch of garlic adds a fresh brightness that balances the warmth of the red pepper flakes. Whether you are using a charcoal or gas grill, these mushrooms are a quick and reliable way to elevate simple supermarket staples into something truly special.

Ingredients for Grilled Spiced White Mushrooms
1 teaspoon coriander seeds
1 teaspoon cumin seeds
2 tablespoons unsalted butter, softened
1/4 cup coarsely chopped fresh flat-leaf parsley
1 to 1 1/2 teaspoons dried hot red pepper flakes
1 small garlic clove, minced
675g medium white mushrooms (2 inches wide), stems trimmed flush with caps
60ml olive oil
1/2 teaspoons salt
1/4 teaspoons black pepper
a mortar and pestle or an electric coffee/spice grinder
How to make Grilled Spiced White Mushrooms
Prepare grill for cooking over medium-hot charcoal (moderate heat for gas). (If using a charcoal grill, open vents on bottom of grill, then light charcoal. When Charcoal turns grayish white (about 15 minutes from lighting), hold your hand 5 inches above grill rack to determine heat for charcoal as follows: Hot: When you can hold your hand there for 1 to 2 seconds; Medium-hot: 3 to 4 seconds; Low: 5 to 6 seconds. If using a gas grill, preheat burners on high, covered, 10 minutes, then, if necessary, reduce to heat specified in recipe.)
While coals are lighting, heat a dry small heavy skillet (preferably cast-iron) over moderately low heat until hot, then toast coriander and cumin seeds, shaking skillet frequently, until a shade darker, 2 to 3 minutes. Transfer seeds to mortar or grinder and cool completely, about 3 minutes, then finely grind.
Transfer ground-spice mixture to a large bowl, then mash into softened butter along with parsley, red pepper flakes (to taste), and garlic until combined well.
Toss mushrooms with oil, salt, and pepper in a bowl, then grill on lightly oiled grill rack, covered only if using a gas grill, turning over occasionally, until lightly browned and tender, 12 to 14 minutes total. Quarter mushrooms while still hot, then toss with butter mixture and salt and pepper to taste.
