French Split Pea Soup (Potage Saint-Germain)
French Split Pea Soup, also known as Potage Saint-Germain, is a classic French dish that is all too often forgotten. Yet it’s simple to make, healthy and super-comforting for winter!

Ingredients for this French Split Pea Soup
Here are the main ingredients for this split pea soup. You’ll find the exact quantities in the recipe card at the bottom of the article.
- Split peas : A superfood! Rich in protein, fiber and minerals like magnesium, potassium and iron. Ideal for a vegetarian diet.
- Onion, carrot, leek and garlic: The essential aromatic base that adds depth to the soup.
- Vegetable broth: Opt for a good-quality broth, preferably low in salt, for a more balanced taste.
- Bay leaves: For a subtle fragrance that goes perfectly with split peas.
- Heavy Cream: For an irresistibly creamy touch. You can replace it with a plant-based heavy cream for a vegan version.
- Lemon juice (optional): It’s not in the traditional recipe, but I love adding a little to add a note of freshness.
- Crispy bacon and soft-boiled egg: To decorate the soup and make it a main course. See here how I make crispy bacon in the oven!

Preparing this Split Pea Soup
Start by rinsing the split peas under cold water.
To make them easier to digest and speed up cooking, soak them in hot water while you prepare the vegetables. Chop the onion, slice the carrot and leek and finely chop the garlic.


Heat a tablespoon of olive oil in a large Dutch-oven over medium heat. Sauté the onion, carrot and leek for a few minutes, until slightly melted. Add the garlic and mix well.

Drain the split peas, then add them to the Dutch-oven with the bay leaves. Pour in the vegetable stock and bring to the boil.
Once the water starts to boil, lower the heat and simmer, covered, for about 45 minutes. The split peas should be tender.


Remove the bay leaves, add the heavy cream and blend using an immersion blender or blender.
The result is a smooth, velvety soup! Adjust the seasoning with salt, pepper and a touch of lemon juice if you want a little more freshness.


Tip: Serve the soup warm with crispy oven bacon – it’s the perfect topping for this split pea soup! ! Add parsley and a soft-boiled egg for even more proteins.

Variants and tips
- Vegetarian version: Replace the bacon with smoked tofu chips or toasted seeds for a crunchy effect.
- Spicy version: Add a pinch of cumin or smoked paprika for an original twist.
- More creaminess: For an even smoother texture, replace the heavy cream with coconut milk.
