Ingredients
Instructions
- Saute sliced onions and garlic in butter until clear. Season with salt and pepper.
- Sprinkle the onions with flour and continue stirring.
- Add liquid, bay leaf, and thyme to the saucepan.
- Cover and simmer for 30 to 40 minutes.
- Float dried bread on the soup and sprinkle with grated cheese before serving.
- For a golden crust, place the prepared soup in ovenproof dishes and bake in a hot oven at 450°F until bubbly and golden brown.
Tips & Substitutions
For added depth, consider using a mix of onions, such as yellow and sweet Vidalia onions. If you're out of gruyère cheese, a good substitute would be a mix of Swiss and parmesan. To save time, use pre-sliced onions or even frozen sautéed onions. Don't skip the bay leaf; it adds essential flavor. For a heartier version, incorporate cooked chicken or sausage, similar to Chicken recipes.
Serving Suggestions
Serve the onion soup gratinée with a side of crusty baguette or a light green salad to balance the richness. A glass of dry white wine pairs beautifully, enhancing the flavors of the soup. For an extra touch, consider sprinkling fresh thyme or parsley on top before serving. This dish is perfect as a starter or a main course, especially during colder months.
Storage & Reheating
Leftover onion soup can be stored in an airtight container in the refrigerator for up to 3 days. To reheat, simply warm it on the stove over medium heat until heated through. If you want to maintain the cheese topping, reheat in an oven-safe dish and broil briefly to restore the crust. Avoid freezing, as the texture may change.
