Ingredients
For the Soup
- 1 kg beef chunks (stew beef or chuck roast, cut into cubes)
- 4 large yellow onions, thinly sliced
- 3 tablespoons butter
- 2 tablespoons olive oil
- 4 garlic cloves, minced
- 1 tablespoon flour (optional, for thickening)
- 6 cups beef broth or stock
- 1 tablespoon Worcestershire sauce or soy sauce
- 1 teaspoon dried thyme (or 1 tablespoon fresh)
- 1 bay leaf
- Salt and black pepper to taste
- Fresh parsley for garnish
For the Toasted Bread
- Baguette or crusty bread slices
- Butter or olive oil
- Optional: grated cheese such as mozzarella, gruyère, parmesan
Preparation Steps
Step 1 – Brown the Beef
Season beef cubes generously with salt and pepper. Heat oil in a large pot on high heat. Add beef in batches and brown all sides. Remove beef and set aside.
Step 2 – Caramelize the Onions
Reduce heat to medium. Add butter and sliced onions. Cook slowly, stirring often, for 15–20 minutes until onions become golden, soft, and sweet. This step is crucial for flavor.
Step 3 – Add Garlic and Flour
Add garlic and cook for one minute until fragrant. If using flour, sprinkle it in now and stir well to slightly thicken the soup.
Step 4 – Combine and Simmer
Return the browned beef to the pot. Pour in beef broth, Worcestershire sauce, thyme, and bay leaf. Bring to a boil, then reduce heat to low. Cover and simmer gently for 1½ to 2 hours, or until beef is tender and broth is flavorful.
Step 5 – Adjust Seasoning
Taste the soup and season with additional salt, pepper, or herbs if needed. Remove bay leaf before serving.
Prepare the Toasted Bread
Step 1 – Slice and Butter
Slice baguette or other crusty bread. Spread lightly with butter or brush with olive oil.
Step 2 – Toast
Place under the broiler or in a hot oven at 200°C (400°F) for 5–7 minutes until golden and crisp.
Step 3 – Optional Cheese
For a cheesy finish, sprinkle with grated mozzarella or parmesan before toasting until melted and bubbly.
Serving
Ladle the hot soup into bowls. Top with toasted bread or serve bread on the side for dipping. Garnish with fresh parsley or chives.
Serve with:
- Side salad
- Roasted vegetables
- Mashed potatoes
- Steamed rice
- Grated parmesan sprinkled directly onto the soup

Slow Cooker Option
Brown beef and onions first, then cook 6–7 hours on LOW or 3–4 hours on HIGH.
Vegetable Boost
Add carrots and celery while simmering for a thicker stew-like version.
Storage and Reheating
Refrigerator

Freezer
