Best Crunchy Baked Tomato Onion Gratin Recipes

THE BEST ONION GRATIN

Steps:

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