Method
Preheat your oven to 220°C (425°F). Place a large, empty baking sheet in the oven while it preheats. Heating the pan in advance is the secret to getting an excellent sear and crispy edges on the mushrooms.
In a large mixing bowl, combine the halved mushrooms and red onion wedges. Drizzle with the olive oil and sprinkle with kosher salt, then toss thoroughly until every piece is evenly coated.
Carefully remove the hot baking sheet from the oven. Spread the mushrooms and onions onto the sheet in a single, uncrowded layer. Roast for 15 to 18 minutes, or until the vegetables have softened and developed dark brown edges.
While the vegetables are roasting, prepare the glaze. In a small bowl, whisk together the harissa paste, maple syrup, and olive oil until smooth and cohesive.
Remove the baking sheet from the oven. Drizzle the harissa-maple glaze directly over the hot mushrooms and onions, tossing gently with a spatula to coat them. Return the pan to the oven for an additional 5 to 7 minutes to caramelize the sugars in the syrup.
While the glaze caramelizes, prepare the base. In a separate bowl, whisk together the cold Greek yogurt, lemon juice, grated garlic, and kosher salt until silky.
To serve, use the back of a spoon to create a wide, swooping bed of the seasoned yogurt across a serving platter. Immediately spoon the blistering hot, sticky mushrooms and onions over the cooling yogurt. Garnish with chopped parsley and serve right away.
Chef's Notes
- Preheating your baking sheet is non-negotiable for superior roasted mushrooms. The immediate sizzle upon contact sears the exterior before the internal moisture has a chance to leak out.
- Not all harissa pastes are created equal in terms of spice level. Taste a tiny amount before mixing the glaze; if yours is exceptionally fiery, cut the amount in half and substitute with a little tomato paste to retain the rich color and body.
- For the absolute best texture, clean your mushrooms by gently wiping them with a damp paper towel rather than washing them under running water. Mushrooms are highly porous and will absorb water like a sponge, which hinders browning.
- The magic of this dish relies on stark temperature contrasts. Ensure your yogurt base remains chilling in the refrigerator until the exact moment you are ready to plate and serve.
Storage
Refrigerator: 3 days — Store the cooked mushrooms and the yogurt base in separate airtight containers to prevent the yogurt from weeping and the mushrooms from becoming soggy.
Reheating: Reheat mushrooms in a skillet over medium-high heat until hot and slightly crisped, then serve over freshly spooned cold yogurt.
