Not Keto
Parsnips
10.50g net carbs per 1/2 cup
Sweet and starchy, half a cup carries 10.5 g net carbs, enough to crowd out most of a day's keto allowance in one side dish. Roast a lower-carb root like radishes or turnips instead when you want that caramelized, tender bite.

Good to Know
Parsnips get noticeably sweeter as they age in cold storage, since starch converts to sugar, so the older roots can carry an even higher carb load than the numbers suggest. Watch roasted recipes that toss them in honey or maple, and steer clear of root-vegetable medleys and chips where parsnips are blended with carrots and beets. If you want that earthy, slightly sweet flavor without the starch, roasted radishes or celeriac give you a closer texture at a fraction of the carbs.
Is Parsnips Keto? The Full Answer
Parsnips contains 10.50g net carbs per 1/2 cup (13.30g total carbs minus 2.80g fiber). Sweet and starchy, half a cup carries 10.5 g net carbs, enough to crowd out most of a day's keto allowance in one side dish. Roast a lower-carb root like radishes or turnips instead when you want that caramelized, tender bite.
On a standard ketogenic diet, most people target 20-25g net carbs per day. A single serving uses 53% of a 20g daily carb limit. If you are following a strict ketogenic protocol, reach for a lower-carb option instead.
Better Keto Swaps
Roasted radishes are your closest stand-in here. They soften and mellow in the oven much like a root vegetable, but a 1/2 cup serving lands around 1 g net carbs. Cauliflower works too, whether you mash it or cut it into chunks for a hash, and a 1/2 cup runs about 1.5 g net. For something with a little more bite, try turnips: they bring a faintly sweet, earthy flavor at roughly 2 g net carbs per 1/2 cup, far below what you saw above.
