“This dish pours a light popover batter on top of mushrooms sauteed with onions, thyme and rosemary. It makes a marvelous brunch dish, or even a light main course for a vegetarian supper. The eggs and milk should be at room temperature to maximize the rise. Recipe from Serious Eats”

Ingredients Nutrition


  1. Preheat oven to 375°F Place a 10" skillet (preferably cast-iron) over medium heat. Melt 1 tbsp butter, then add onion. Saute until onion is soft and translucent, about 5 minutes.
  2. Turn heat up to medium-high. Add mushrooms, garlic, 1 tsp salt, thyme, rosemary and 1/8 tsp pepper. Cook, stirring occasionally, until the mushrooms wilt, most of the water evaporates, and the mushrooms begin to brown, 10-15 minutes. Transfer mushrooms and onion to a bowl.
  3. While the mushrooms cook, combine eggs, milk, flour, remaining salt and remaining pepper in a blender. Blend until smooth and allow to stand at room temperature until the mushrooms are cooked.
  4. Clean out the skillet. Melt the remaining 1 tbsp of butter in the skillet, swirling the pan to coat the sides as well as the bottom. Return the mushrooms and onions to the pan and spread into one even layer. Pour the batter over the top and shake gently to help it sink down.
  5. Transfer the skillet to the oven and bake until puffy and golden brown, 25-30 minutes. Cut into wedges and serve warm or at room temperature.
