MUSHROOM SPINACH BAKED EGGS RECIPE

Mushroom Spinach Baked Eggs Recipe image

Number Of Ingredients 9

2 tablespoons extra-virgin olive oil, plus more for brushing
1 small onion, chopped
1/2 pound white mushrooms, sliced
Kosher salt and freshly ground pepper
6 cups baby spinach (about 6 ounces)
6 slices potato bread, lightly toasted
6 large eggs
1/2 cup whole milk
3/4 cup shredded Gruyère cheese

Steps:

Heat the olive oil in a large skillet over medium-high heat. Add the onion and cook, stirring occasionally, until golden, about 8 minutes. Add the mushrooms and cook, undisturbed, until they begin to brown, about 2 minutes. Add 1/2 teaspoon salt, and pepper to taste; continue cooking, stirring occasionally, until soft, about 4 more minutes. Stir in the spinach and cook until wilted, about 2 minutes. Remove from the heat and let cool. Brush a 9-by-13-inch baking dish with olive oil. Arrange the bread in the dish in a single layer with the edges slightly overlapping, then spoon the mushroom-spinach mixture on top. If making ahead, cover and refrigerate overnight.
