What's the difference between onion soup and French onion soup?
While there are many similarities between onion soup and French onion soup, the main difference are the ingredients. With a French onion soup you start with yellow onions and beef stock.
With the non-French version you can vary in the types of onion and stock. In this recipe, for example, vegetable stock is used with which you get a vegetarian soup. You can also opt for a chicken broth, but then this version won't be vegetarian anymore.
The ingredients
This easy onion soup contains only 6 ingredients. Optionally, you can serve it with slices of baguette topped with grated cheese.

How do you prepare this easy onion soup?

Step 1: Cut the onions into rings and chop the garlic fine. Melt the butter over low heat and add the onion rings. Cook for 3 minutes until the onions are translucent. Then add the garlic and fry for 30 seconds. Frying the onions and garlic gives them more flavor.

Step 2: Pour the vegetable stock and Worcestershire sauce with the onions. Also add the thyme. Bring to a boil and simmer for 15 minutes. Taste and season with salt and pepper (if necessary).
Optional

Step 3: Cut the baguette into thick slices and sprinkle with the grated cheese. Cut the baguette diagonally so that the slices look even better.

Step 4: Place the slices of baguette on top of the soup and slide it under the grill for 3 minutes, so that the cheese melts. Serve immediately and beware it is burning hot!
