Ingredients Needed

Here’s everything you’ll need to make a healthier, delicious French Onion Soup from scratch:

Yellow onions (6 large) – The heart and soul of French Onion Soup. They’ll be slowly caramelized to bring out that deep, sweet, savory flavor.
Olive oil (2 tablespoons) – A healthier fat alternative to butter. It gives a rich, subtle flavor without being overly greasy.
Low-sodium vegetable broth (6 cups) – This keeps the soup savory without overloading it with salt.
Dry white wine (1/2 cup) – A bit of acidity to balance the sweetness of the caramelized onions.
Garlic (4 cloves, minced) – For that aromatic, garlicky depth of flavor.
Fresh thyme (2 sprigs) – A perfect herb to elevate the soup’s complexity.
Bay leaves (2) – These add an herbal note that balances out the sweetness of the onions.
Whole wheat baguette (1 loaf, sliced) – A healthier alternative to traditional white baguette. The texture holds up nicely when toasted.
Grated part-skim Gruyère cheese (1 cup) – Gruyère is the classic cheese for French Onion Soup, but using part-skim cuts down on fat.
Fresh parsley (1 tablespoon, chopped) – To garnish and add a burst of color and freshness.

Cooking Instructions

Now that you’ve got your ingredients, let’s walk through how to pull this all together.

Caramelize The Onions
- Heat olive oil in a large soup pot over medium heat. Add the onions and a pinch of salt, stirring them occasionally.
- Cook for 30-40 minutes, stirring often to avoid burning. The goal here is to let the onions break down and slowly caramelize, turning golden brown and sweet. Don’t rush it-patience is key!
Deglaze With Wine
- Once the onions are caramelized, pour in the dry white wine. This step deglazes the pot, lifting all those flavorful brown bits from the bottom of the pan. Let the wine simmer for 3-5 minutes, reducing slightly.
Add Broth And Herbs
- Add the low-sodium vegetable broth, garlic, thyme, and bay leaves to the pot. Stir to combine and bring to a simmer.
- Reduce the heat to low and let it simmer for another 20-30 minutes to allow the flavors to meld together.
Prepare The Toast
- While the soup is simmering, preheat your oven to 375°F (190°C).
- Slice your whole wheat baguette into 1-inch slices and place them on a baking sheet. Toast them in the oven for 8-10 minutes, until crispy and golden brown.
Assemble The Soup
- Ladle the hot soup into oven-safe bowls. Place a slice of the toasted baguette on top of each bowl, then sprinkle a generous amount of grated Gruyère cheese over the bread.
Broil To Finish
- Place the bowls under the broiler for 2-3 minutes, or until the cheese is melted and bubbly. Watch closely, as the cheese can burn quickly under the broiler.
Serve And Garnish
- Sprinkle some fresh parsley on top for a burst of color and a fresh flavor contrast. Serve hot and enjoy the comforting goodness.

Ingredient Insights

Let’s take a moment to break down some of the key ingredients and why they’re so perfect for a healthy version of this soup:

Onions: Not just the base for flavor, onions are packed with antioxidants and fiber. They help lower cholesterol, boost immune function, and aid in digestion. Plus, caramelizing them brings out their natural sweetness, eliminating the need for added sugar.
Olive oil: A heart-healthy fat, olive oil is rich in monounsaturated fats, which are great for cardiovascular health. It also adds a subtle richness without overwhelming the dish.
Low-sodium broth: Using low-sodium broth ensures you control the salt content. Excess sodium can lead to bloating and high blood pressure, so it’s always a good idea to go with a reduced-sodium version when possible.
Whole wheat bread: Whole grains like whole wheat bread contain more fiber and nutrients compared to white bread. It’s a good source of B vitamins and can help stabilize blood sugar levels.
Gruyère cheese: While Gruyère is a bit indulgent, using part-skim Gruyère reduces the fat content while still delivering that signature melty, gooey texture and nutty flavor.

Expert Tips

Caramelizing onions: This step requires patience. The slower you cook the onions, the more intense and sweet the flavor becomes. Don’t rush it-let them slowly develop a deep, golden color. It can take up to 40 minutes, but it’s totally worth it.
Wine substitution: If you prefer to avoid alcohol, you can substitute the white wine with a splash of apple cider vinegar or lemon juice. These will add the necessary acidity without the alcohol content.
Make ahead: French Onion Soup actually tastes even better the next day, as the flavors have had more time to develop. Feel free to make the soup ahead of time and store it in the fridge for up to 3 days.
Cheese options: If you don’t have Gruyère on hand, you can use a lighter Swiss cheese or even mozzarella. Just make sure it’s a cheese that melts well!

Recipe Variations

Vegan version: To make this soup entirely plant-based, swap the cheese for a vegan cheese alternative and use a vegan broth. You can also leave out the butter altogether and just use olive oil.
Gluten-free version: Simply replace the whole wheat baguette with a gluten-free bread option. Many gluten-free breads work great for toasting and can hold up just as well in the soup.
Add protein: If you want to make the soup more filling, consider adding some cooked lentils or even shredded chicken to the broth.
Herb variations: If thyme isn’t your thing, feel free to experiment with other herbs like rosemary or sage. They’ll change the flavor profile but still pair nicely with the onions.

Final Words

French Onion Soup is all about balance-sweet caramelized onions, savory broth, and the perfect layer of cheese. With this healthier recipe, you don’t have to feel guilty about indulging in this rich, comforting dish. By making simple swaps like using olive oil, low-sodium broth, and part-skim cheese, you can create a soup that’s both nourishing and satisfying.
