Homemade Vegan French Onion Soup

Hello! I am back with another delicious onion recipe! You guys loved my Caramelized Onion Tart so much, therefore, I decided to share this French onion soup recipe with you!

Onions – either you hate them or love them. I LOVE them and enjoy them almost daily. Not only are they very healthy (read further down below for more information), but they also add a very nice flavor to almost all savory dishes. Especially caramelized onions. They are so damn good!

This recipe is not a traditional French onion soup because I added a healthy twist, which you might love as much as I do.

How To Make Vegan French Onion Soup?

As mentioned before, this is not a classic or original French onion soup because I love to add a healthy and unique twist to all my recipes. Most French onion soups are quite boring in my opinion, therefore, I added red lentils to the soup. I will tell you later why I did it.

Now, let’s see how easy this soup recipe is. Full instructions and measurements are in the recipe card below!

STEP 1: You will need to caramelize the onions first. This step takes quite a while but is very important, as we want the onions nicely caramelized and flavorful. Don’t rush and turn the heat too high because this might burn the onions, and we don’t want that.

STEP 2: Once the onions are nicely caramelized and soft, you can add the garlic and thyme. I used fresh thyme but feel free to use dry thyme.

STEP 3:Add the wine and let simmer until reduced almost completely. Also, add the lentils, veggie broth, and bay leaves. If you don’t want to use lentils, you can thicken the soup now with 2 tbsp of flour or cornstarch. Bring the soup to a boil and let it cook on low heat for about 20 minutes or until the lentils are tender.

STEP 4:Meanwhile, slice your favorite bread and pick your favorite vegan cheese. I made my Easy Vegan Cheese Saucewhich takes less than 5 minutes. Toast the bread until nicely brown and add cheese on top once the soup is done.

STEP 5: Remove the bay leaves from the soup. Taste the soup and adjust seasonings. Add more salt/pepper/thyme to taste and also add tamari or soy sauce.

STEP 6: Pour the soup into oven-safe small bowls. Place one to two slices of bread on top of each soup bowl. You can add even more vegan cheese of choice (e.g. vegan mozzarella). Place the bowls under the broiler for a couple of minutes or until the cheese gets bubbly. Serve immediately.

Why Red Lentils?

Lentils will slightly thicken the soup and furthermore add healthy plant-based protein. They add an interesting touch to this vegan French onion soup and make it even more delicious, in my opinion. If you aren’t a fan of lentils, simply leave them out. You can easily thicken the soup with flour or cornstarch.

Are Onions Healthy?

Absolutely! Onions are super healthy. They contain lots of antioxidants, minerals, and vitamins. In this article, I read about 9 incredible health benefits of onions which I want to share with you.

1. Packed With Nutrients

Onions are low in calories yet high in nutrients, including vitamin C, B vitamins and potassium.

2. May Benefit Heart Health

Research shows that eating onions may help reduce heart disease risk factors, such as high blood pressure, elevated triglyceride levels and inflammation.

3. Loaded With Antioxidants

Red onions are rich in anthocyanins, which are powerful plant pigments that may protect against heart disease, certain cancers and diabetes.

4. Contain Cancer-Fighting Compounds

A diet rich in allium vegetables like onions may have a protective effect against certain cancers.

5. Help Control Blood Sugar

Due to the many beneficial compounds found in onions, consuming them may help reduce high blood sugar.

Calories 444 kcal

Ingredients

  • 2 tbsp vegan butter (see notes)
  • 5 medium (1000 g) onions sliced
  • 3-4 garlic cloves minced
  • 1/2 cup (120 ml) red wine (see notes)
  • 1/2 cup (100 g) red lentils (see notes)
  • 5 cups (1200 ml) vegetable broth
  • 1 1/2 tsp fresh thyme or 1/2 tsp dried
  • 2 bay leaves
  • 1 1/2 tsp sea salt or more to taste
  • Black ground pepper to taste
  • 1 tbsp tamari or soy sauce
  • 1/2 baguette or bread of choice (gluten-free if needed)
  • 6 oz (180 g) vegan cheese of choice

Instructions

  • This recipe has a video for easy visual instructions.

  • Heat vegan butter in a large pot over medium heat and add the onions. Cook on low to medium heat until soft and caramelized, about 40 minutes, stirring every few minutes to avoid burning. After about 20 minutes, add salt and pepper to taste.

  • Once the onions are caramelized and soft, add garlic and thyme and sauté for about 1 minute.

  • Stir in the wine and let simmer for about 5-6 minutes or until the wine is reduced almost completely. Add the lentils (if you don't want to use lentils, you can thicken the soup now with 2 tbsp of flour or cornstarch) and also add the vegetable broth, and bay leaves.

  • Bring the soup to a boil and let it simmer for about 20 minutes or until the lentils are tender, stirring occasionally.

  • Meanwhile, slice your favorite bread (check my Gluten-Free Bread Recipe) and pick your favorite vegan cheese. I made my Easy Vegan Cheese Sauce.

  • Once the soup is done, carefully remove the bay leaves. Taste the soup and adjust seasonings. Add more salt/pepper/thyme to taste and also add tamari or soy sauce.

  • Preheat the broiler and toast the bread until nicely brown. Add vegan cheese on top.

  • Pour the soup into oven-safe small bowls. Place one to two slices of bread on top of each soup bowl. Place the bowls under the broiler for a couple of minutes or until the cheese gets bubbly.

  • Serve immediately and enjoy!

Notes

  • You can use vegan margarine or oil (e.g. olive oil) instead of vegan butter.
  • Use a dry red wine. White wine is fine as well. If you don't want to use wine, simply skip it and use 2-3 tablespoons of balsamic vinegar instead.
  • I used red lentils to add a healthy twist to this French Onion Soup. Lentils will thicken the soup, and they also add healthy plant-based protein. If you don't want to use lentils, I would suggest thickening the soup with 2 tbsp of flour (or cornstarch).
  • Feel free to add more herbs or spices of choice. I sometimes also add rosemary and red pepper flakes.
  • Recipe serves 4. Nutrition facts are for one serving.

FAQs

How do you deepen the flavor of French onion soup? ›

Asian fish sauce, cider vinegar, and sherry add depth and complexity to the broth.

Why do you put baking soda in French onion soup? ›

The caramelized onions for this soup cook more quickly due to a pinch of baking soda but still have that deep, slow-cooked flavor. Topping the soup with hot, cheesy toasts prepared while the soup simmers, eliminates the need to bake the soup in specialty French onion soup bowls.

What is the difference between onion soup and French onion soup? ›

What is the Difference Between Onion Soup and French Onion Soup? French onion soup is always made with beef stock. Other onion soups can be made with chicken, vegetable, or beef stock. Additionally, French onion soup typically contains wine or sherry, which isn't typical or necessary in other onion soups.

Should French onion soup be thick or thin? ›

Made slightly thicker than most watered down soups because every mouthful NEEDS a slightly thickened texture to compliment the caramelized onions.

What gives vegetable soup that depth of flavor? ›

A squeeze of citrus, a dollop of yogurt or a drizzle of cream, a dusting of cheese or a good chile powder, a sprinkling of some herbs or croutons — all can take a perfectly fine soup into the realm of the delectable. Even a spiral of good olive oil to finish and some coarse sea salt can do wonders.

How do you make soup taste stronger? ›

You can extract a clean, strong broth from a combination of water and several pantry ingredients. It's all about layering powerful flavor-enhancers that you probably already have on hand—bacon, tomato paste, herbs, peppercorns, a Parmesan rind, and, of course, kosher salt.

What is the best wine to use in French onion soup? ›

For French onion soup, consider reaching for a red wine with spice notes, such as Cabernet Sauvignon or Pinot Noir. These varietals add a subtle kick of pepper and earthiness that play well with the soup's rich flavors.

Why do you put lemon juice in soup? ›

While salt can be added to balance out this richness, using lemon instead will actually be more effective. This is because the acid from the lemon cuts through the fat and balances out the spices. Using lemon zest on top of each bowl is also a great garnish that provides a zesty punch in every bite.

How caramelized should onions be for French onion soup? ›

The key to good French onion soup is to cook the onions so long that they threaten to melt into a viscous, dark brown paste, à la Marmite. As has already been extensively reported in Slate, there are no shortcuts when you're caramelizing onions; it always takes at least an hour, usually longer.

How to doctor up canned French onion soup? ›

Some fresh rosemary or thyme brings a woody, peppery taste to the soup, complementing the umami flavor of the beef stock. With a splash of balsamic vinegar and green onions or fresh basil as a garnish, the canned soup is transformed from a grocery store original into a gourmet dish.

How do you get the most Flavour out of onions? ›

Soak in Vinegar: It only takes about 15 minutes. Soaking raw onions in acid rinses away the harsh flavors and adds pleasant tartness. Soak in Water: Even water washes away those pesky sulfuric flavors. A quick 15-minute soak does the trick.

How do you reduce acidity in French onion soup? ›

You can try adding a pinch of baking soda, a small amount of sugar, or a splash of dairy such as milk, cream, or yogurt. These ingredients can help to balance out the acidity and make the soup more palatable.

How do you add depth of flavor to chicken soup? ›

For a deeply flavorful chicken soup, get some boneless, skinless chicken thighs, season them, brown them in a skillet, then finish them in a 375 F oven. You can refrigerate them until you're ready to make the soup, then simply dice them up and add them to the soup at the very end.
