French Onion Soup
This homey, comforting soup is perfect for a cool fall evening. I love Bob’s Pain aux Lardons because those little bites of bacon just make the soup even more delicious. You don’t have to use the veal demi-glace, but it’s worth it for the richer flavor.

Ingredients
- 2 tablespoons butter
- 2 tablespoons olive oil
- 2 pounds sweet onions, thinly sliced
- 1 teaspoon sugar
- 2 cloves garlic, minced
- 4 sprigs thyme
- 2 tablespoons flour
- ½ cup white wine
- 1 quart beef stock
- 2 tablespoons veal demi-glace, optional
- 2 cups Gruyere cheese, grated
- 4 half slices Bob's Pain aux Lardons
Instructions
- In a heavy-bottom cast-iron pot, melt the butter and olive oil together until hot. Add the onions and sugar and cook down slowly, keeping the heat on medium or medium-low. As they cook and soften, scrape up the browned bits and stir so that they don’t burn. Cook the onions until they are golden brown, about an hour and a half.
- When the onions are soft and brown, add the garlic and thyme, then add the flour. Cook 2 minutes. Add the white wine and cook until it is completely evaporated, stirring constantly. Add the stock and demi-glace and stir to combine. Bring to a simmer and cook slowly for about 30 more minutes.
- Preheat the broiler.
- Remove the thyme sprigs. Pour the soup into 4 small oven-proof bowls on a lined baking sheet. Top with a slice of bread and then a generous mound of cheese. Put under the broiler until the cheese bubbles and browns.
