Inspired by classic French-style vegetable soups, this recipe relies on slow cooking and careful layering rather than heavy seasoning. Potatoes give body, fennel adds quiet sweetness, and cream rounds everything out. The result is a soup that feels calm and grounding, like a familiar routine that always works.
3 tablespoons olive oil
1 large yellow onion, chopped
2 large fennel bulbs, trimmed and sliced
2 pounds Yukon Gold potatoes, peeled and diced
4 cups chicken stock or vegetable stock
1 teaspoon salt, or to taste
½ teaspoon freshly ground black pepper
1 cup heavy cream
2 tablespoons fresh dill or parsley, finely chopped
Build the base – Heat olive oil over medium heat. Add the chopped onion and sliced fennel, then cook for 8–10 minutes, stirring often, until soft and lightly translucent. Keep the heat moderate so the vegetables soften without browning.
Add the potatoes – Stir in the diced potatoes, coating them in the oil and vegetables. Cook for 2–3 minutes to help them absorb flavor.
Form the broth – Pour in the stock, add salt and black pepper, and bring the mixture to a gentle boil. Stir once or twice to combine everything evenly.
Simmer until tender – Reduce the heat and simmer uncovered for 20–25 minutes, until the potatoes are very soft and easily pierced with a fork.
Blend until smooth – Remove the pot from heat and blend the soup until completely smooth, working in batches if using a countertop blender.
Finish with cream – Return the soup to low heat, stir in the cream, and warm gently without boiling.
Serve fresh – Taste and adjust seasoning, then garnish with chopped dill or parsley before serving.
