Parsnips Guide: How to Cook, Cut & Store Them

Parsnips spend most of the year quietly waiting in the produce aisle for someone to notice them, wedged between the carrots that get all the attention and the turnips nobody asked for. That's a shame, because a parsnip roasted properly is sweeter than either one. Here's everything you need to actually use them.

What Do Parsnips Taste Like?

Parsnips look like pale carrots, and botanically they're close cousins, but the flavor is its own thing. Raw, they're starchy and a little peppery, similar to a mild radish. Cooked, especially roasted, they turn sweet and nutty, almost like a cross between a carrot and a sweet potato, with a slightly earthy, aromatic finish. Parsnips left in the ground through a frost taste even sweeter, since the cold converts some of their starch to sugar.

Parsnips vs. carrots: Carrots are sweeter raw and hold their sweetness at a steady level. Parsnips are more neutral raw but get noticeably sweeter and more complex once cooked, especially roasted or caramelized.

Parsnips vs. turnips: Turnips are peppery and slightly bitter, closer to a radish or mustard green in flavor. Parsnips are sweeter and milder, with none of the bitterness turnips can have.

Parsnips vs. celery root (celeriac): Celery root tastes savory and herbal, like a cross between celery and potato. Parsnips are sweeter and starchier, with no celery-like flavor at all. The two aren't interchangeable, though they show up in a lot of the same winter root vegetable mixes.

How to Peel and Cut Parsnips

Whether you need to peel a parsnip depends on its age and size, not a fixed rule.

Young, small parsnips: The skin is thin and the flavor is concentrated just under it, so a good scrub with a vegetable brush is enough. No peeler needed.

Older, larger parsnips: The skin toughens and can get waxy, so it's worth peeling with a vegetable peeler. Large parsnips can also develop a fibrous, woody core down the center. Halve the parsnip lengthwise and cut out the core if it looks tough or pale, since it won't soften no matter how long you cook it.

To cut: trim the top and tail, then halve lengthwise. For roasting or air frying, cut into batons or wedges so they caramelize evenly. For boiling or mashing, cut into smaller, even chunks so everything cooks through at the same rate. Uniform sizing matters more with parsnips than with a lot of vegetables, since a too-thick piece can stay starchy in the middle while the outside is done.

How to Cook Parsnips

Roasted

Toss cut parsnips with oil, salt, and pepper. Roast at 400 to 425°F for 30 to 50 minutes, depending on how thick you cut them, flipping halfway through. They're done when the edges are browned and a fork slides in easily. A drizzle of honey or maple syrup in the last 10 minutes leans into their natural sweetness.

Air Fryer

This is the fastest route to the same result. Toss cut parsnips with oil and seasoning, then air fry at 400°F for 12 to 15 minutes, shaking the basket halfway through. If you're used to converting oven recipes for the air fryer, our Air Fryer Converter can help you scale times and temps for other vegetables the same way.

Boiled

Cut into 1-inch pieces and boil in salted water for about 10 minutes, until fork-tender. This is the step before mashing, or a way to par-cook parsnips before finishing them in a hot oven for a shorter roast.

Mashed

Boil until fork-tender, drain well, and mash with butter and a splash of cream or milk, the same way you'd make mashed potatoes. Parsnips mash up naturally sweeter and a little looser, so start with less liquid than you think you need.

Storing and Freezing Parsnips

In the Fridge

Loosely wrapped or bagged in the crisper drawer, fresh parsnips keep for about 2 to 3 weeks. Some extension sources note they can hold even longer, up to a few months, in a very cold, humid environment closer to root cellar conditions, but for a standard home fridge, plan on the shorter end. Cooked parsnips keep for 3 to 4 days refrigerated, though some sources recommend using them within 2 days for best quality.

In the Freezer

Peel and cut into ½-inch cubes, then blanch in boiling water for 2 minutes before an ice bath of the same length. Drain and dry thoroughly, then freeze in an airtight container or bag. Blanched parsnips keep for 8 to 12 months in the freezer. If you're at 5,000 feet elevation or higher, add 1 minute to the blanch time, since water boils at a lower temperature at altitude and needs a bit longer to fully stop the enzyme activity that causes frozen vegetables to lose flavor and texture.
