Vegan French Onion Soup, a classic made vegan

Four small casseroles filled with bread pudding, reminiscent of a savory onion soup, rest on a baking tray. Topped with shredded cheese and herbs, they exude comfort. A gold spoon rests in one dish. In the background, two glasses of red wine and a red napkin are set against a blue textured wall.

About this recipe

This vegan French onion soup is to die for. It is easy, delicious, and comforting. This is the classic French recipe, but it is made in a 100% plant-based version.

French onion soup is one of my favorite soups of all time. I love the flavor: sliced onions stewed until caramelized, then covered with toast and gratin cheese—it’s really the best. You can make it vegetarian and use regular cheese.

A red pot filled with thinly sliced white and purple onions, ready for a comforting onion soup, sits on a marble countertop. A red and white striped cloth is visible at the bottom right corner, partially tucked into the pot's handle.

INGREDIENTS OF VEGAN ONION SOUP

Onion. Use the onions that you prefer or have at home. You can combine or use all of the same types. When choosing onions, make sure that they are firm and well-formed and that the shell that protects them is not broken.
Olive oil and butter (I use the Miyoko’s brand).
Bay leaves and thyme, like all the spices you use, look for fresh spices so that when you open the jar or the bag, your entire space will be filled with their aroma.
Garlic
Vegetable broth can be homemade or purchased. If you buy it, look for the best one, choosing one that contains only vegetables.
Baguette bread or homemade bread.
Melty Cheese. I use vegan cheese. Use the brand and type that you like the most, shredded or sliced.

A close-up of a pot with caramelized onions hints at the makings of a rich onion soup. The light brown, seasoned interior cradles golden-brown onions at the bottom. A red-and-white dish towel beside it suggests recent handling, all set against a pristine white marble surface.

DIFFERENT WAYS TO PREPARE IT

Without oil. If you are on an oil-free diet, you can sauté the onion in vegetable broth. To do this, put the onion over medium heat with a quarter cup of broth. Leave the onion until it is caramelized and the broth evaporates. This method can be used for any recipe.
For the cheesy bread.
- One way is to serve the soup in oven-proof bowls, top with sliced or diced baguette and shredded or sliced cheese. Place the bowls in the oven or broiler until the cheese melts.
- Another is to put the bread with grated or sliced cheese at the bottom of the bowl and serve the hot soup on top.
- The last step is to melt the slices of bread with cheese in the oven and get the sliced bread toasted. Then serve the soup and top it with the slice of bread with melted cheese

✨TIPS✨

Freezes very well. An important tip is that this vegan onion soup can be frozen. The day you prepare it, prepare twice as much and thus freeze a portion. You can freeze in individual portions so that you only get what you need. Do not freeze with the bread and cheese.
Add red wine to it. If you want a little stronger flavor and/or want to use this soup for a romantic dinner, add red wine to the already caramelized onions before adding the broth and water.

A hand with pink-painted nails uses a gold fork to take a bite from a baked dish reminiscent of onion soup. The dish includes cheesy bread topped with shredded cheese and herbs, served in round, patterned ramekins on a baking tray. A glass of red wine and a small bowl are in the background.

Soup pot

Ingredients

2 large onions thinly sliced (I used yellow and red)
2 tablespoons olive oil
2 tablespoons vegan butter
1 bay leaf
¼ teaspoon dried thyme
1 teaspoon salt
2 whole garlic cloves, sliced
2 cups water
2 cups vegetable broth
6 slices of baguette bread or any other French bread
6 slices vegan cheese
fresh chopped parsley

Instructions

In a large saucepan, add the olive oil and butter, and set over medium heat. When the butter melts, add the onion and let it caramelize for about 5 to 7 minutes.
Add the bay leaf, thyme, salt, garlic, vegetable broth, and water. Cover and leave on low heat for 10-15 minutes.
Meanwhile, turn the oven to the broiler function. Place the bread slices on a baking sheet, put a slice of cheese on top of each piece, and put it under the broiler for 3-5 minutes.
To serve, serve the soup in a bowl and top each one of them with a piece of bread with melted cheese. Sprinkle with the chopped fresh parsley.
Serve immediately.

Notes

To make the oil-less version, set a soup pot over medium heat, and when it is hot add a quarter cup of vegetable broth and add the onion and caramelize as you normally do.
If you feel that it lacks umami flavor you can add a tablespoon of soy sauce.
You can use pure vegetable broth instead of the combined water broth
