Ingredients

2 tablespoons extra-virgin olive oil

8 oz fresh mixed wild mushrooms (oyster, shiitake, or cremini), sliced

1 medium yellow onion, thinly sliced

2 cloves garlic, minced

1 teaspoon fresh thyme, minced

2 cups fresh spinach, coarsely chopped

8 large eggs

1 cup whole milk

1 teaspoon Dijon mustard

½ teaspoon salt

¼ teaspoon ground black pepper

1 cup shredded Gruyère cheese

Cooking spray (for muffin tin)

Instructions

  1. Preheat oven to 325°F (165°C). Coat a 12-cup muffin tin with cooking spray.
  2. Heat olive oil in a large nonstick skillet over medium-high heat. Add mushrooms in an even layer and cook undisturbed for 4 minutes. Stir and cook another 5 minutes until tender.
  3. Add onion and cook about 4 minutes until softened. Stir in garlic and thyme; cook 2 minutes until fragrant.
  4. Add spinach and cook until wilted, about 2 minutes. Remove from heat.
  5. In a large bowl, whisk together eggs, milk, Dijon mustard, salt, and pepper.
  6. Stir in Gruyère cheese and the mushroom-spinach mixture.
  7. Divide evenly among muffin cups.
  8. Bake uncovered for 30 minutes, until puffed and set. A toothpick inserted should come out clean.
  9. Cool slightly, then remove from the pan. Serve warm or store for later.

Notes

  • Thaw and squeeze frozen spinach well if substituting for fresh.
  • Use muffin liners or grease well to prevent sticking.
  • Try adding cooked bacon, ham, or sausage for a heartier version.
  • Swap Gruyère for cheddar, mozzarella, or feta to vary flavors.
  • Cool completely before freezing for meal prep.
