Tomato and Mushroom Gratin – Oma's Tomaten-Champignon-Gratin

by: Gerhild Fulson  / Oma Gerhild shares easy, authentic German recipes you can trust, rooted in family tradition and featured in her cookbooks.

This vegetarian Tomato and Mushroom Gratin, aka Tomaten-Champignon-Gratin, is easy to prepare. Served with a salad, it makes a great lunch or supper meal anytime of year.

It's also a great way to use up some day-old bread.

A hot meal in the summer? Why not? This gratin is quickly prepared and is only in the oven for ½ hour. Not long enough to heat up the kitchen. But long enough to make this a delicious vegetarian dish. 

Why is this called a "gratin"?

Doesn't sound very German. Well, German it is. Using a "non-German" word just sometimes elevates the dish to a "higher" standard. 

Want to make it more German? Use Emmentaler Cheese instead.

Not a vegetarian? This is a great side dish for almost any meat. This would be great along with this recipe for fried fish called "Bratfisch" that you can make on the stove while you are waiting for the gratin to bake.

This gratin would also go great with the smoked pork chops recipe called "Kasseler". Since the meat is already smoked and cooked, it only needs to be briefly fried to finish it off.
