Soup Base

Method

Soup Base

1

Prepare onions

Peel and halve the onions from root to tip. Lay cut-side down and thinly slice into half-moons so you have about 2.5 lb of thin slices.

2

Caramelize onions

In a large heavy-bottomed pot or Dutch oven, melt the unsalted butter with 1 tablespoon olive oil over medium heat. Add the sliced onions, sprinkle with 1 tsp kosher salt and 1 tsp granulated sugar. Cook, stirring every 2–3 minutes, adjusting heat as needed to maintain a steady gentle sizzle. Continue for 35–45 minutes until onions are deep golden-brown and jammy. If onions begin to stick, reduce heat and scrape the fond from the bottom with a wooden spoon.

3

Deglaze

Increase heat to medium-high, add the dry white wine (or 1/4 cup water if omitting wine) and use a wooden spoon to scrape up browned bits from the bottom. Let the wine reduce by half, 3–4 minutes.

4

Build the broth

Add the beef stock and chicken stock (if using) to the pot along with the bay leaves, thyme sprigs, and 1 tsp Worcestershire sauce. Bring to a simmer, then reduce heat to low and simmer gently, uncovered, for 20–25 minutes to allow flavors to meld. Taste and season with sea salt and freshly ground black pepper to taste.

5

Finish

Remove and discard thyme sprigs and bay leaves. Keep soup warm while you prepare bread and cheese.

Bread & Cheese Topping

6

Toast baguette

Preheat oven to 425°F (220°C). Arrange baguette slices on a baking sheet, brush both sides lightly with 1 tablespoon olive oil. Toast in the oven 6–8 minutes, flipping once, until edges are golden and crisp.

7

Rub with garlic

Remove toasted slices from oven and, while still warm, rub the cut side of the halved garlic clove over the top of each slice to impart a light garlic flavor.

8

Assemble croûtes

Generously pile grated Gruyère onto each toasted baguette slice. Sprinkle each with a little grated Parmesan if using. Place slices on a baking sheet and set oven to broil (or 500°F/260°C if your oven broil runs hot).

9

Melt cheese

Broil the assembled croûtes 1–3 minutes, watching carefully, until cheese is bubbling and lightly browned. Remove from oven and set aside.

Serve

10

Preheat oven-safe bowls or crocks if you have them (place in a low oven for a few minutes) or simply use warm bowls. Ladle the hot soup into 4 oven-safe bowls (about 1.5 cups soup per serving).

11

Float 1–2 cheese-topped baguette slices on each bowl of soup (or place croûte on top of bowl). If bowls are oven-safe, place under broiler 1–2 minutes to further brown cheese and create a melded topping — watch carefully. Otherwise serve immediately with croûtes on the side.

12

Garnish with a light grind of black pepper and an optional sprinkle of fresh thyme leaves. Serve hot.
