Easy Zucchini Gratin

Easy Zucchini Gratin

Ingredients

Serves 6

4 large zucchini (or 6 medium), sliced into ¼-inch thick rounds

2 small onions, finely chopped

1 tablespoon butter

1 egg

½ cup crème fraîche (or sour cream or heavy cream)

¾ cup shredded cheddar cheese (or, better yet, gruyere cheese)

1 teaspoon salt

¼ teaspoon ground black pepper

4 tablespoons grated Parmesan cheese

Directions

Preheat oven to 375°F (190°C) and place a rack in the middle.

Grease a 9x13-inch baking dish (or a large cast-iron skillet) and set aside.

Melt butter in a large skillet over medium heat. Add onions and sauté for 6 minutes, until translucent. Add zucchini rounds and sauté for 10 to 12 minutes, stirring every so often. Remove from the heat and set aside.

In a medium bowl whisk egg, créme fraîche, half of the shredded cheddar cheese, salt, and pepper.

Add zucchini to the baking dish and spread on an even layer. With the back of a spoon press them down gently.

Pour the egg mixture over the vegetables and sprinkle with remaining shredded cheddar cheese and with the Parmesan cheese.

Bake in the oven for 25 to 30 minutes or until golden brown on top.

Serve!
