Scalloped Onions with Wild Mushrooms

Yield: 6 servings

Ingredients:

• 1 ounce dried wild mushrooms (cèpes, porcini or morels)
• 4 pounds Vidalia or yellow onions, thinly sliced
• 1 tablespoon chopped fresh thyme (or 1/2 tablespoon dried)
• 1/2 cup milk
• 1 egg
• 1/2 teaspoon pepper
• 1 teaspoon Kosher salt
• 1/4 pound freshly grated Gruyère cheese

Directions:

1. Preheat oven to 350 degrees F.
2. Rehydrate dried mushrooms in 1 1/2 cups warm water for 20 to 30 minutes.
3. Heat butter in a large sauté pan. Sauté onions for 8 minutes, lifting and turning occasionally with tongs to insure even browning.
4. Coarsely chop mushrooms, add to onions and sauté an additional 3 minutes. Add thyme and transfer vegetables to a casserole or gratin pan.
5. Beat egg with pepper, salt and milk. Pour the milk and egg mixture over vegetables, then cover with Gruyère cheese.
