Step 1

Preheat oven to 375 degrees.

Step 2

Wash and dry the mushrooms. Slice the mushrooms into thin slices.

Step 3

Add 2 tablespoons of butter to a 10 inch oven-safe skillet over medium heat. Once melted, add the mushrooms and let cook for 4-5 minutes, stirring often.

Step 4

Add the garlic to the skillet and cook until fragrant, about 30 seconds. Stir in the spinach and continue cooking until the spinach has wilted, stirring occasionally. Turn up the heat to let any excess liquid evaporate from the pan.

Step 5

Transfer the mushroom and spinach mixture to a bowl.

Step 6

Add the eggs, cream, salt, and pepper to a large mixing bowl and whisk until smooth. Stir the spinach and mushrooms into the eggs along with the Parmesan.

Step 7

Return the skillet to low heat and add the remaining tablespoon of butter. Once melted, pour the egg mixture into the skillet.

Step 8

Place the skillet in the oven and bake for 15-20 minutes or until the top is puffy and the edges are turning golden.

Step 9

Let sit for 5 minutes before slicing and serving.
