Muffin Tin Spinach & Mushroom Mini Quiches

Switch up your morning routine with these easy vegetarian mini quiches. Earthy mushrooms and spinach pair nicely with rich and creamy Gruyère cheese. Serve them on a platter with a fresh fruit salad for a simple weekend brunch.

Ingredients

2 tablespoons extra-virgin olive oil
8 ounces fresh mixed wild mushrooms (such as oyster and shiitake), sliced
1 cup thinly sliced yellow onion
1 tablespoon minced garlic
2 teaspoons minced fresh thyme
1 (5 ounce) package fresh spinach, coarsely chopped
8 large eggs
⅔ cup whole milk
2 teaspoons dijon mustard
½ teaspoon salt
½ teaspoon ground pepper
¾ cup shredded gruyère cheese

Directions

Preheat oven to 325 degrees F. Heat oil in a large nonstick skillet over medium-high heat. Add mushrooms in an even layer; cook, undisturbed, until browned on the bottom, about 4 minutes. Stir and continue to cook, stirring occasionally, until browned all over, about 5 minutes. Add onion; cook, stirring occasionally, until beginning to soften, about 4 minutes. Stir in garlic and thyme; cook, stirring, until fragrant, about 2 minutes. Add spinach; cook, stirring constantly, until just wilted, about 2 minutes. Remove from heat.
Whisk eggs, milk, Dijon, salt and pepper in a large bowl. Stir in cheese and the mushroom mixture. Coat a standard 12-cup muffin tin with cooking spray. Divide the mixture among the prepared muffin cups. Bake, uncovered, until puffed and set, about 30 minutes. Remove from the pan and serve immediately.
