Mushroom, Leek, and Cheese Frittata

Mushroom, eggs and fontina cheese frittata.

Mushroom, leeks, and fontina cheese go into this frittata

Throughout this Lenten season I’ve been trying to cut back on the amount of meat we consume, incorporating more fish and other seafood, or going completely meatless.  Today’s recipe features a one-pan entree where eggs and cheese provide the main protein, and meaty mushrooms and leeks provide the vegetables.

A frittata is is an egg based dish, somewhat like a quiche without a crust, a little like an omelet only baked.  Hard to describe, but if you like eggs in any form you can’t miss with this dish.   Frittatas are eggs-cellent served hot or at room temperature, which means you can do it ahead.  It would be a great addition to brunch, make a light lunch, or a meatless main meal served with another vegetable and a salad as I did.

In the version you see pictured here I made only half the recipe for two of us, and we had about half of it left for another time.  Also the recipe calls for Baby Bella mushrooms, but I used Shitaki mushrooms.  I would not do that again as they do not have enough natural moisture for this kind of recipe.  Shitakis need to be cooked in a liquid in order to become tender, so I found that in this recipe they were a little tough.  Fontina is the suggested cheese to use here because it has a mild flavor and excellent melting properties.  A good substitute would be muenster or edam cheeses.
