Cream of Parsnip Soup
Cream of parsnip soup is a smooth, velvety vegan soup made by roasting parsnips with onion, garlic, and rosemary, then blending them with vegetable broth and a splash of cooking cream. Roasting is the whole trick here: it draws out the parsnips’ natural sweetness and gives the soup a deep, cozy flavor you never get from boiling. It’s comforting, quick, and ready with barely any effort, which makes it my go-to when the weather turns cold.
Why Parsnips Deserve a Spot in Your Soup Pot
Parsnips are one of the most underrated root vegetables, if you ask me. At least here in Romania, they mostly get tossed into the pot when making a clear soup, alongside carrots, celery, and onion, and that’s about it. But the parsnip can be so much more than a background vegetable. I don’t even know how to describe the flavor: a little sweet, with a herby note, since parsnips are related to parsley. If you want to experiment with them, I’m here to help.
I have three arguments to convince you this soup is worth making. It’s super flavorful and not boring at all. It’s extremely cheap to make. And it’s ready in no time with not much effort. This is why I recommend it to families on a budget and to students as well. Give parsnips another chance and help them shine the way they deserve.
The Secret Is Roasting, Not Boiling
Although parsnips are usually boiled, their true flavor shines when they’re roasted. Here’s the food-science reason: roasting drives off water and concentrates the sugars already in the parsnip, and the dry heat lets them caramelize at the edges. Boiling does the opposite, leaching flavor out into the water and leaving the vegetable waterlogged. Roasting the onion, garlic, and rosemary on the same tray builds a second layer of savory, aromatic depth before anything ever hits the blender. If you like roasted vegetables as much as I do, like roasted butternut squash, then you should give this recipe a try. Trust me, you’ll keep asking yourself, “Why didn’t I think of this before?!”
What Goes Into This Soup
- Parsnips are the star. Pick firm, pale roots that aren’t rubbery or sprouting. Very large parsnips can have a woody core, so trim it out if it feels tough.
- Yellow onion and garlic roast alongside the parsnips and melt into the background, adding sweetness and savory depth.
- Fresh rosemary is the one herb here, and it earns its place. Its piney, resinous aroma pairs beautifully with the parsnips’ sweetness. One sprig is plenty.
- Vegetable broth or water thins the soup to the consistency you want. Broth gives a richer result; water keeps it lighter and lets the parsnip lead.
- Vegan cooking cream makes it silky. I used Alpro rice cuisine, but any plant-based cooking cream works.
- Extra virgin olive oil, salt, and pepper round everything out. The oil helps the vegetables roast and brown properly.
Tips for the Silkiest Cream of Parsnip Soup
- Cut even cubes. Uniform pieces roast at the same rate, so nothing burns while the bigger chunks are still raw in the middle.
- Roast until fully tender. At 200 degrees C it takes about 30 to 40 minutes. You want a fork to slide through with zero resistance and the edges lightly golden. Undercooked parsnip blends grainy.
- Add the liquid gradually. Pour the broth and cooking cream into the blender a little at a time until you hit the consistency you like. It’s easy to loosen a thick soup, much harder to thicken a runny one.
- Season at the end. Grind the black pepper and add salt after blending, tasting as you go, since roasting already concentrates flavor.
What to Serve With It
If you decide to make this soup, I recommend serving it with some bread croutons or crunchy crackers for contrast against all that velvet. I think it’s the perfect autumn and winter soup, since all the ingredients are widely available in supermarkets and at the farmer’s market during the cold seasons. If you’re building a cozy soup rotation, it sits happily next to my cream of mushroom soup with thyme and my creamy carrot ginger soup. You’ll find it filed with the rest of my vegan autumn recipes too.
Storing and Reheating
This soup keeps well in an airtight container in the fridge for up to 4 days, and it reheats gently on the stove over low heat, stirred now and then. If it thickens as it sits, loosen it with a splash of broth or water. It also freezes nicely, so roast and blend a double batch when parsnips are cheap and stash half for a busy weeknight. Reheat from frozen or thawed, and give it a good whisk to bring the creaminess back together.
I really hope you’ll try this cream of parsnip soup soon and fall in love with it as deeply as I did. If you roast up a tray and blend a batch, come back and leave a star rating and a comment to tell me how it turned out, whether you served it with croutons or gave the rosemary a swap. I read every one.

Frequently Asked Questions
Yes. This version is fully plant-based. It uses vegan cooking cream (I used Alpro rice cuisine, but any brand works), extra virgin olive oil, and vegetable broth, with no butter, dairy cream, or other animal products. It’s a naturally dairy-free way to get a rich, velvety cream soup.
Roast them. Roasting drives off water and concentrates the parsnips’ natural sugars, caramelizing the edges for a deeper, sweeter flavor. Boiling leaches flavor into the water and leaves the vegetable waterlogged. Roasting the onion, garlic, and rosemary on the same tray adds even more depth before blending.
Parsnips have a flavor of their own that has nothing to do with carrots, even though they look like a big white carrot. It’s a little sweet with a herby, parsley-like note. Roasting brings out the sweetness, and the rosemary adds a piney, savory contrast that makes the soup taste cozy and warming.
Roast at 200 degrees C for about 30 to 40 minutes. They’re ready when a fork slides through with zero resistance and the edges are lightly golden. Fully tender parsnips blend into a smooth cream, while undercooked pieces blend grainy, so give them the extra few minutes if you’re unsure.
Roast the parsnips until completely tender, then add the vegetable broth and vegan cooking cream to the blender gradually until you reach the consistency you want. It’s easy to loosen a thick soup but hard to thicken a runny one, so add liquid in stages. A high-speed blend gives the silkiest texture.
Yes. It keeps in an airtight container in the fridge for up to 4 days and freezes well, so a double batch is a smart move when parsnips are cheap. Reheat gently over low heat, loosen with a splash of broth or water if it has thickened, and whisk to bring the creaminess back together.
I 100% agree: parsnips are truly underrated. This soup does them justice, Ruxandra!
