The Best Onion Gratin

• 4 medium red onions, peeled and quartered
• sea salt & freshly ground black pepper
• 8 sprigs fresh thyme, leaves picked
• 2 garlic cloves, peeled and sliced
• 1 glass white wine
• 4 tablespoons creme fraiche
• 2 ounces gruyere cheese, grated
• 2 ounces fresh grated parmesan cheese

1. Preheat oven to 400u0b0F.
2. Break the onion quarters apart to give you little "petals".
3. Place these in an A4 sized dish or earthenware oven dish.
4. Drizzle with olive oil, add salt and pepper, and toss in the thyme and garlic.
5. Mix well, add white wine and cover tightly with two layers of tinfoil.
6. Bake for 45 minutes, then remove tinfoil, and put back in oven for 15 minutes until slightly golden.
7. Stir in creme fraiche (or sour cream) and sprinkle with cheeses.
8. Turn oven down to 350F and put back in oven until cheese is golden and melted, about 15 minutes.
9. You can eat right away, or cool it down and flash it under the grill when the guests arrive.
10. Enjoy!
