This savory mushroom Yorkshire pudding is a showstopping brunch dish with crisp, golden edges and a soft, airy center. It is filled with buttery mushrooms, shallots, herbs, and poached eggs for a rich vegetarian breakfast or weekend lunch.
Make the Yorkshire pudding batter. In a bowl, whisk 2 eggs with the flour until smooth, then slowly whisk in the milk to form a lump-free batter. Season with salt and black pepper, then whisk in the porcini powder if using. For the best rise, let the batter rest while the oven heats, or chill it for up to 24 hours.
Heat the oven to 220°C/200°C fan/gas 8. Add the sunflower oil to a 20 cm ovenproof frying pan or skillet and place it in the oven until the oil is very hot. Carefully pour in the batter, return the pan to the oven, and bake for 20 minutes until puffed and deep golden. Reduce the oven to 180°C/160°C fan/gas 4 and cook for 5 minutes more to set the center.
While the Yorkshire pudding finishes baking, prepare the mushrooms. Melt the butter in a second frying pan over medium-high heat until foaming. Add the shallot, garlic, and sliced mushrooms, then cook for 3-4 minutes, stirring often, until the mushrooms are golden and tender. Add the sherry or white wine, simmer for 1 minute, then remove from the heat. Stir in the chopped parsley and season to taste.
Poach the remaining 2 eggs just before serving. Bring a small pan of water to a gentle simmer and add the white wine vinegar. Crack in the eggs and cook for 2-3 minutes, until the whites are set and the yolks are still soft. Lift out with a slotted spoon and drain on kitchen paper.
Spoon the mushroom mixture into the hot Yorkshire pudding. Top with the poached eggs, season with a little more salt and black pepper, scatter over extra parsley, and serve immediately from the pan.
A very hot pan and oil are essential for a tall, crisp Yorkshire pudding, so avoid opening the oven during the first 20 minutes. Chestnut, button, cremini, or mixed wild mushrooms all work well. The batter can be made a day ahead, but the finished pudding is best served straight away before it softens.
