1 tablespoon olive oil
8 ounces white button mushrooms sliced
10 ounces fresh spinach
6 ounces crumbled feta cheese

US Customary - Metric

Instructions

Preheat oven to 375 degrees. Coat a muffin tin with nonstick cooking spray. In a medium bowl (ideally with a spout), beat eggs and salt and pepper to taste (I like 1/2 teaspoon salt and 1/4 teaspoon pepper). Set aside.
In a large skillet over medium-high heat, heat oil until shimmering. Add mushrooms and ¼ teaspoon salt and cook until softened and the mushrooms have released most of their liquid, about 5 minutes.
Using a slotted spoon, remove mushrooms from skillet to a mixing bowl, leaving any remaining oil and liquid in the skillet.
To the skillet with the liquid, add spinach and 1/4 cup of water. Cook spinach until wilted, about 5 minutes.
Add the spinach to the bowl with the mushrooms. Stir in the cheese. Divide the mixture evenly among 12 muffin cups.
Divide the beaten egg mixture among the muffin cups, filling each nearly to the top. Bake until a toothpick inserted comes out clean, about 25 minutes.
Cool slightly before removing from muffin tins (the egg cups should come out easily). Serve hot or at room temperature. Store leftovers in the refrigerator and use within 4 days.

Notes

White button mushrooms: Or baby portobellos. Just be sure to clean whichever you choose (more tips about how to clean mushrooms below in the "Recipe FAQs") and remove the stems.
Fresh spinach: I prefer starting fresh and wilting it just a bit in a skillet, but you could certainly trade in defrosted frozen spinach, squeezed dry in a kitchen towel, if that's what you have on hand.
Feta cheese: Goat cheese or blue cheese crumbles would also be terrific, if you prefer those over tangy, salty feta.
Yield: This Egg Muffin recipe creates 12 savory muffins. For a protein-packed breakfast, eat 4 muffins (this contains 3 whole eggs). For parties or snacks, 1 or 2 egg muffins makes a good serving size.
Storage: Transfer any leftover cooked Egg Muffins to an airtight container and refrigerate for up to 4 days. To reheat, warm in the microwave for about 1 minute.
Freezer: Transfer the cooked Egg Muffins to a sheet pan or plate(s) in a single layer, then freeze them individually. Once frozen, transfer the Egg Muffins to a freezer-safe bag and freeze for up to 2 months. For best results, thaw any frozen Egg Muffins in the refrigerator overnight, then reheat in the microwave for about 1 minute or until warmed through. Alternatively, bake the Egg Muffins straight from the freezer; transfer to a sheet pan and cook in a 400-degree oven for 5 to 10 minutes.
