What Are Rutabagas and How Can I Use Them?

If rutabagas have turned up in a recipe or caught your eye at the store, here's what you need to use them with confidence and how to choose them, cook them, store them, what to substitute, and 6 recipes to try them in.

Key Points

Golden-fleshed root, a cabbage-turnip cross, sweeter and earthier than a turnip
Roast at 425°F (220°C) or boil 20 to 30 minutes to bring out the sweetness
Known as swede or neep in Britain and Ireland, often labeled "turnip"
Undercooking leaves it dense and bitter, so cook it longer than potato
Whole roots keep weeks in the crisper; peel the food-grade wax first

What are rutabagas?

Rutabaga is a large, round root vegetable with golden-yellow flesh and a purple-and-tan skin, sweeter and earthier than a turnip with a gentle peppery edge. It is a cross between a cabbage and a turnip, which is exactly why it tastes like both.

Cooked, the flesh turns deep yellow-orange and silky, sweetening as it caramelizes. Raw, it is crisp and a little sharp, fine grated into slaws. It is a cold-weather staple across Northern Europe, where it goes by swede or neep.

The name confusion is worth clearing up: in much of Britain and Ireland a rutabaga is called a "swede" or "turnip," so old recipes for "turnip" mash often mean this golden root, not the smaller white-and-purple turnip.

Cooking With Rutabaga

Rutabaga is at its best when heat brings out its sugars. Roasting is the easiest win: peel, cube, toss with oil, and roast at 425°F (220°C) until the edges turn brown and sweet, the approach behind Roasted Root Vegetables With Cumin & Coriander.

Mashing is the other classic. Boil the cubes until fork-tender, around 20 to 30 minutes, then mash with butter; pairing it with potato softens the flavor, as in Rutabaga-Potato Casserole. Rutabaga Pudding (Irish) bakes a sweetened mash into a custardy side.

It also melts into long-cooked dishes. Cut into chunks, it holds its shape through a braise and soaks up the broth in Irish Lamb Stew with Root Vegetables & Green Peas and a Root Vegetable Hash.

Glazing turns it into a side dish with real character, the trick behind Glazed Vegetables.

Pairings and Common Mistakes

Rutabaga loves warm spices and fat. Butter, cream, brown sugar, maple, nutmeg, cumin, and black pepper all flatter it, and it stands up to strong partners like lamb, bacon, and sharp cheddar.

The biggest mistake is undercooking it. Raw rutabaga is dense and can taste bitter and waxy, so give it real time; it needs longer than a potato to turn tender and sweet.

The second is fighting the thick skin with a paring knife. The waxed skin is tough, so cut a flat base, stand the root upright, then peel down the sides with a sturdy knife or a heavy peeler.

Substitutes

Turnips are the closest swap, milder and more watery, so they cook faster and taste less sweet. Use them one-for-one but expect a lighter result.

Parsnips bring similar sweetness with a softer, more delicate texture and are good in roasts and mashes. Celery root and waxy potatoes also stand in for mash, though both lose the peppery note.

For roasting, a mix of carrot and turnip mimics rutabaga's sweet-earthy balance fairly well.

Buying & Storing Rutabaga

Pick rutabagas that feel heavy and firm for their size, with smooth, unblemished skin. Smaller-to-medium roots, around the size of a softball, are sweeter and less woody than the giant ones, which can turn fibrous and bitter at the core.

Most rutabagas come coated in food-grade wax to slow moisture loss, which is normal; just peel it away before cooking.

Stored in the fridge crisper, a whole rutabaga keeps for several weeks, even a month or more. Peeled and cubed, it lasts about four or five days in a sealed container, or freeze blanched cubes for several months.
