To get a good sear on mushrooms, use high heat, a heavy-bottomed pan, and avoid overcrowding the pan. Ensure the mushrooms are dry before cooking.
Achieving a perfect sear on mushrooms involves several key steps:
Preparation: Start by cleaning the mushrooms. Avoid soaking them in water, as they will absorb it and steam instead of sear. Gently wipe them clean with a damp cloth or brush.
Cut Evenly: Cut the mushrooms into uniform sizes. This ensures they cook evenly and sear at the same rate.
Dry the Mushrooms: Pat the mushrooms completely dry with paper towels. Excess moisture is the enemy of a good sear.
High Heat: Use a heavy-bottomed pan, such as cast iron or stainless steel, over high heat. The pan needs to be hot before adding the mushrooms.
Oil: Add a high-smoke-point oil, like vegetable, canola, or avocado oil, to the hot pan. Ensure the pan is lightly coated.
Avoid Overcrowding: Add the mushrooms to the pan in a single layer, leaving space between them. Overcrowding lowers the pan's temperature and causes the mushrooms to steam instead of sear. Cook in batches if necessary.
Don't Move Them Too Soon: Let the mushrooms sit undisturbed for several minutes until a golden-brown crust forms on the bottom. Resist the urge to stir them constantly.
Season: Season with salt and pepper towards the end of the cooking process. Adding salt too early can draw out moisture.
Flip and Sear: Once the first side is seared, flip the mushrooms and sear the other side until golden brown and tender.
Don't wash mushrooms under running water. They are like sponges and will absorb the water, preventing them from browning properly. Instead, use a mushroom brush or a slightly damp paper towel to gently clean off any dirt.
