Why This Recipe Works
Most grilled vegetables turn out either mushy or burnt. The secret to avoiding both? The soapstone. This thick cooking surface distributes heat evenly and prevents hot spots that char vegetables before they cook through. It also gives you restaurant-quality sear marks without the flare-ups that come from dripping oil hitting flames.
The chili crisp mayo sauce is the game-changer. Creamy mayo tempers the heat from chili crisp while soy sauce adds umami depth. A splash of bourbon in the sauce (and optionally flambéed over the top) brings caramelized sweetness and a touch of drama to an otherwise simple veggie cook.
This is beginner-friendly because there's no precision required—vegetables are forgiving. Slightly undercooked? They're al dente. Slightly charred? Even better. As long as your soapstone is properly preheated, you're getting great results.
Why the Big Joe and Soapstone are Perfect for This
The Big Joe's 24-inch cooking diameter gives you room to spread vegetables in a single layer—no crowding, no steaming. Crowded vegetables release moisture and steam instead of char. With the Big Joe's generous space, every piece gets direct contact with the hot soapstone for proper caramelization.
The soapstone is essential here. It heats slowly and evenly, holding steady temps once preheated. Unlike cast iron that can create scorching hot spots, soapstone radiates gentle, consistent heat that chars vegetables without burning them. The porous surface also prevents sticking without needing excessive oil.
At 425-475°F, the Big Joe maintains perfect vegetable-grilling temperature. Hot enough to char and caramelize natural sugars, but not so hot that exteriors burn before interiors cook. The ceramic construction holds this temp rock-steady for the entire 15-20 minute cook—something gas grills struggle with when you're constantly opening to flip vegetables.
