Mashed potatoes earn their place on the table because they are cheap, forgiving, and built to catch gravy. They are also not the only vegetable that can do that job. Six others mash into a soft mound, hold a ladle of sauce, and cost less per serving than the casserole or takeout they replace – and each one brings something the russet does not.
This round-up covers six stand-ins we cook on rotation: golden beets, turnips, rutabaga, celery root, cauliflower, and white sweet potato. Every section gives selection and prep, an exact method in US measures with a doneness cue you can actually check, the sauce we’d serve over it, and how the batch prices out against a 5-pound bag of russets – about $3 to $4 at most US grocers, prices vary by store.
These are not disguises. A mashed turnip tastes like a turnip, and a good one tastes like it should. Where an entry is bitter, sweet, peppery, or wetter than potato, this list says so plainly, because the fix for all four is the same: salt, fat, and the right gravy.
Golden Beets, Silky and Mild
Golden beets are the mildest of the beet family and the one most willing to play the part of a potato. Look for beets 1 to 1.5 inches across, heavy for their size, with smooth skin and firm shoulders. Small beets cook evenly; oversized ones go woody in the middle. Scrub, trim the tops to 1/2 inch, and leave 1 inch of stem so the color doesn’t bleed out during cooking.
Method: Cover the beets with cold salted water by 1 inch and bring to a boil, then simmer 30 to 40 minutes. Doneness cue: a paring knife should slide through the center of the largest beet with no chalky resistance at all – pull one and cut it. Drain, cool under running water for 30 seconds, and the skins slip off under your thumb. For a 6-serving batch, mash 2.5 lb peeled beets with 2 tbsp butter, 3 tbsp warm cream, 1 tsp salt, and 1/4 tsp black pepper. A potato masher leaves pleasant flecks; a ricer makes it silk.
Serve with: Beef braises and burgundy-style pan gravies – the wine and the beets meet in the middle, and a teaspoon of balsamic vinegar in the mash bridges the gap. Cost: golden beets at $2.50 to $4 a pound make this batch about $9 to $12, roughly double a potato batch. Taste note: mild, faintly sweet, earthy in a clean way. Red beets work but push the mash pink and carry a stronger mineral edge.
Turnips, Done Right
Turnips have a reputation they mostly earned from being overcooked. Choose small white globe turnips, 1 to 1.5 pounds each, firm and heavy, with greens attached if you can get them – the greens sauté separately. Big, soft, or sprouting turnips are the bitter ones. Peel thickly, cut into 1-inch chunks, and keep the pieces even so nothing turns to mush before the center cooks.
Method: Simmer in salted water 15 to 18 minutes. Doneness cue: the edges turn translucent and a fork presses a chunk flat without a chalky core. Drain well and let the colander sit 2 minutes. Mash 2.5 lb cooked turnip with 2 tbsp butter, 3 tbsp warm cream, and salt to taste. The blend that wins people over: 2 parts turnip to 1 part parsnip, boiled together – peel the parsnips, cut out any woody core, and cube them the same size. Parsnip takes about the same time; add the turnip 3 minutes after the parsnip if your pieces differ.
Serve with: Turkey or chicken gravy, which covers a lot of ground; a knob of butter and coarse pepper works over pork chops too. Cost: turnips at $1 to $1.50 a pound plus parsnips at $2 to $3 puts this batch at $6 to $8, only a couple of dollars over potatoes. Taste note: young turnips are mild and peppery; mature ones turn sharp and bitter, which is exactly what the parsnip sweetness rounds out.
Rutabaga, the Gateway Mash
Rutabaga – swede, to some tables – is firmer and sweeter than a turnip, and it behaves most like a potato once cooked. Pick one that’s heavy and solid, 2 to 3 pounds, with no soft spots or shriveled skin; the thick waxy peel comes off easier after a partial cook. Cut it in half first, then peel in sections with a sharp knife – a vegetable peeler slips off the wax.
Method: Cube into 1-inch pieces and simmer in salted water 20 to 25 minutes. Doneness cue: a fork crushes a piece flat with no grainy center. Drain, return to the hot pot off the heat for 60 seconds, then mash 2.5 lb rutabaga with 2 tbsp butter, 1/4 cup warm milk, 1/2 tsp salt, and a whisper of nutmeg or white pepper. The gateway ratio: half rutabaga, half russet – 1.5 lb of each – cooked together and mashed as one. It’s the version that converts a doubtful table before you serve the pure thing.
Serve with: Beef gravies, browned sausage, and pork roasts; the sweetness stands up to a deeply browned pan sauce where a delicate mash would collapse. Cost: at $1 to $1.50 a pound, this batch lands near $6 to $7, about the same as potatoes once you count butter and milk. Taste note: sweeter and denser than potato, with a faint mustard-like finish that salt and black pepper keep in check.
Celery Root, Cream and Butter
Celery root – celeriac – arrives as a knobby, soil-dusted ball and rewards the five minutes it takes to peel it properly. Choose 1 to 1.5 pound specimens that feel heavy and firm; avoid any with soft crevices. Slice off the top and bottom so it sits flat, then cut the peel away in vertical strips with a knife – the skin is too craggy for a peeler. Work fast if you’re prepping ahead: drop the cut pieces into a bowl of water with 1 tbsp lemon juice per quart so they stay pale.
Method: Steam the 1-inch cubes over simmering water, covered, 15 to 18 minutes rather than boiling them – celery root takes on water easily and a waterlogged mash is the one real failure here. Doneness cue: a knife tip enters a cube the way it enters room-temperature butter. Drain, then mash with 3 tbsp butter and 1/4 cup warm cream; pass it through a ricer if you want it glossy.
Serve with: Cream-and-mustard pan sauces, roast chicken, and pork – a pinch of nutmeg in the mash pulls it toward the meat. Cost: celery root runs $2 to $3.50 a pound, so a 1.5-pound head feeding 4 to 6 costs about $5 to $6, a bit over a potato batch. Taste note: savory with a clear celery backbone, mellow and never bitter once cooked, though the raw vegetable smells stronger than the finished mash tastes.
Cauliflower, Without the Water
Cauliflower earns its place only when it’s cooked twice: browned first for flavor, steamed second for tenderness. Boiling a whole head is how you get the flat, wet version people complain about. Start with 1 large head, about 2 lb, cut into even florets – the stem is good eating, so trim rather than discard it.
Method: Toss the florets with 1 tbsp oil and 1/2 tsp salt, spread on a sheet pan, and roast at 425 °F for 20 to 25 minutes until the edges are genuinely brown. Transfer to a pot with 1/4 cup water, cover, and steam 5 to 8 minutes. Doneness cue: a knife slides through a thick stem with no squeak. Drain in a colander and wait 2 minutes – that pause is what keeps the mash tight. Mash 2 lb cooked florets with 2 tbsp butter, 2 tbsp cream, and salt; an immersion blender makes it smooth, a masher leaves it pleasantly rustic.
Serve with: Cheese sauce, brown-butter drippings, or a mustard-cream sauce over fish and chicken. Cost: one head at $2 to $4 feeds six, making it the cheapest batch on this list, on par with or under potatoes. Taste note: properly roasted, it’s nutty and sweet; boiled, it’s flat and watery. The difference is the oven, not the vegetable.
White Sweet Potato, Kept Savory
The pale-fleshed sweet potato is the closest cousin on this list – same family, similar starch, a texture that mashes almost exactly like a russet. Buy dry, firm, unblemished tubers of even size so they cook at the same rate; the pale-skinned Japanese and Caribbean types range from gently nutty to frankly sweet, so salt is the tool that decides which way this goes.
Method: Scrub, peel, and cut into 3/4-inch cubes. Steam 15 to 18 minutes, or simmer 12 to 15 minutes. Doneness cue: a skewer slides through without a chalky center, and a cube squashes flat under a fork. Mash 2 lb cooked sweet potato with 2 tbsp butter, 2 tbsp warm cream, 3/4 tsp salt, and 1/4 tsp black pepper. Then hold the line: no marshmallow, no brown sugar, no cinnamon. This is the savory bowl, and it should read that way on the plate.
Serve with: Brown-butter sage, sausage gravy, or turkey pan drippings – the savory elements keep the sweetness in its lane. Cost: at $1 to $1.50 a pound, a 6-serving batch runs about $6 to $9, in the middle of the pack. Taste note: some pale varieties are barely sweet and starchy, others noticeably dessert-like. If yours runs sweet, add another pinch of salt and a splash of soy before you add more butter – and a 50/50 blend with cauliflower is a legitimate way to pull it back.
How to choose, at the market. Six batches, one decision rule: match the vegetable to the sauce. Anything brown and wine-dark – beef bourguignon, braised short ribs, pot roast – wants rutabaga, turnip, or golden beet. Creamy sauces and roasted poultry want celery root or cauliflower. Sausage, pork, and pan gravies with drippings handle white sweet potato without a fight.
For a first attempt, buy two vegetables: 2 lb of rutabaga and 1 lb of parsnip, or a small celery root and a head of cauliflower. Cook one on Sunday, refrigerate it, and reheat covered at 325 °F for 25 to 30 minutes with a splash of warm milk. Every mash here holds 2 days refrigerated and reheats better than it sounds – the flavor settles overnight, which is more than you can say for a russet that’s been sitting under a warmer.
Budget-wise, expect $6 to $14 a batch against $4 to $5 for potatoes, with turnips and rutabaga cheapest and golden beets and celery root dearest. That gap buys variety, and at six servings the difference is under a dollar a plate. Prices vary by store – winter roots go on sale in weeks when the produce section is otherwise quiet, and that is when we buy in bulk and mash twice.
