Why You’ll Love Potato, Spring Onion and Turnip Potage Recipe

This soup proves that a short ingredient list can still deliver plenty of flavor. The potatoes make it creamy, the turnips add a subtle peppery sweetness, and the spring onions or leeks bring a mellow savory depth. It is easy to prepare, cooks mostly unattended, and works equally well as a light lunch, a cozy dinner, or an elegant starter. You can also leave it a little chunky for a hearty bowl or puree it until silky smooth for a more polished finish.

Ingredients

(Tip: You’ll find the full list of ingredients and measurements in the recipe card below.)

2 tablespoons butter
5 or 6 medium spring onions or leeks, or a combination, sliced and washed thoroughly
4 medium yellow potatoes, peeled and cut into 1-inch pieces
1 pound turnips, peeled if large, trimmed, and cut into 1-inch pieces
A few sprigs of thyme, plus extra for garnish
1 1/2 teaspoons salt
5 cups water
A few tablespoons heavy cream

Directions

Melt the butter in a large soup pot or Dutch oven over medium heat.
Add the spring onions or leeks, potatoes, and turnips. Toss everything in the butter and cook, stirring, for 1 to 2 minutes.
Add the thyme, salt, and water.
Bring the mixture to a boil, then lower the heat to a gentle simmer.
Partially cover the pot and cook for 30 to 40 minutes, or until all the vegetables are very tender.
Serve as is for a rustic texture, or blend for a smoother soup if preferred.
Finish each serving with a splash of heavy cream and a few fresh thyme leaves.

Variations

A smooth blended version is perfect if you want a more elegant presentation. For a chunkier, more rustic soup, simply mash some of the vegetables lightly and leave the rest intact. You can swap all or part of the spring onions with leeks for a slightly deeper flavor. For a richer finish, add a little extra cream before serving. If you want more herbal flavor, garnish with extra fresh thyme. Croutons or crusty bread on the side also make this soup feel more substantial.

Storage/Reheating

Store leftover soup in an airtight container in the refrigerator for up to 4 days. Reheat gently on the stovetop over low to medium heat, stirring occasionally, until warmed through. You can also reheat individual portions in the microwave in short intervals, stirring between each one. If the soup thickens after chilling, add a splash of water or broth while reheating to loosen it. For best texture, add the cream after reheating if possible.

FAQs

Can I use leeks instead of spring onions?

Yes, leeks work very well in this recipe and give the soup a slightly deeper, sweeter allium flavor.

Do I need to peel the turnips?

Small, tender turnips may not need peeling, but larger turnips usually taste better peeled because the skin can be tougher.

What kind of potatoes work best?

Yellow potatoes are a great choice because they become tender and creamy without falling apart too much.

Can I blend the soup?

Yes, this soup can be served rustic or pureed until smooth, depending on the texture you prefer.

Is heavy cream necessary?

The cream adds richness, but the soup will still be delicious without it if you want a lighter finish.

Can I make this ahead of time?

Yes, this soup is a good make-ahead recipe and often tastes even better after the flavors have had time to settle.

Can I freeze it?

Yes, you can freeze it, though the texture may change slightly once thawed. Freeze it before adding cream for the best result.

How do I clean spring onions or leeks well?

Slice them and soak them in a bowl of water, then lift them out so any grit stays at the bottom.

What should I serve with this soup?

Crusty bread, buttered toast, or simple croutons all pair nicely with the soup.

How can I make it feel more filling?

Serve it with bread, add extra potatoes, or top it with croutons for a heartier meal.
