Recipe Yield: 2–3 servings
INGREDIENTS
2 large yellow onions, thinly sliced
4 cups beef broth (low-sodium recommended)
2 tbsp butter
1 tsp garlic powder
1/4 tsp black pepper
1 tbsp Worcestershire sauce
4 slices crusty baguette or French bread
1 cup shredded Gruyère or Swiss cheese
INSTRUCTIONS
1. Sauté the onions:
In a large saucepan or Dutch oven, melt butter over medium heat. Add sliced onions and cook, stirring occasionally, for 20–25 minutes until golden and soft.
2. Simmer the soup:
Stir in garlic powder, black pepper, Worcestershire sauce, and beef broth. Bring to a gentle boil, then reduce heat and let simmer for 10–15 minutes to develop flavor.
3. Toast the bread:
While soup simmers, preheat your broiler. Place bread slices on a baking sheet, sprinkle with shredded cheese, and broil until melted and bubbly—1 to 2 minutes.
4. Assemble and serve:
Ladle hot soup into bowls and top each with a cheesy toast. For extra indulgence, place the toasts right in the soup and broil the whole bowl for 1–2 minutes if oven-safe.
Helpful Tips to Perfect This Recipe
- Choose Sweet Onions: Yellow onions offer the best balance of sweetness and depth when caramelized slowly.
- Use Day-Old Bread: Slightly stale bread holds up better under the cheese without getting soggy too fast.
- Try a Cheese Blend: Gruyère is classic, but a mix of mozzarella and Parmesan adds an extra gooey and salty twist.
