Choose your texture
- 183°–185°FCrisp-Tender

Best for
- Carrots
- Beets
- Parsnips
Notes
- Flash in a skillet with butter and herbs after the bath.
- Season with citrus zest to keep flavors bright.
Tips
- Cut vegetables to equal size so they cook evenly.
- Dry thoroughly before searing to avoid oil spatter and helps produce caramelization.
- Add a pinch of baking soda to the finishing sauté for extra browning if you like.
- 188°–190°FMelt-in-Mouth
- Soft root vegetables for mashes, purées, or whipped sides.
Best for
- Carrots
- Celery root
- Parsnips
Notes
- Blend with butter + stock for an instant purée.
- Finish with miso butter or brown butter for richness.
Tips
- Reserve some cooking liquid to adjust purée consistency after blending.
- Add a knob of cold butter at the end for extra sheen.
- If making mash, pass through a ricer for silky-smooth texture.
- 194°–198°FCaramelized & Crispy
- Tender vegetables with crisp, browned edges after roasting.
Best for
- Potatoes
- Sweet potatoes
Notes
- Chill briefly, then smash and roast in hot fat.
- Toss with harissa or chimichurri after crisping.
Tips
- Chill cooked potatoes before smashing so they stay fluffy inside and crisp outside.
- Use a high smoke point fat (duck fat, ghee, avocado oil) for roasting.
- Flip halfway through roasting to brown both sides.
Get it ready
- Scrub or peel the vegetables and cut them into even pieces.
- Season with salt, butter or oil, and your favorite herbs or spices.
- Arrange everything in one flat layer in a food-safe bag, then seal.
- Keep the bag fully submerged while the vegetables cook.
Finish and serve
- Take the vegetables out of the bag and pat the surface dry.
- Toss with butter, oil, glaze, or the reduced bag juices.
- Roast, broil, or sauté until the edges brown, then finish with herbs or citrus.
Useful tips
- Root vegetables at 183°–185°F for 1–2 hours cook more evenly than roasting, boiling, or steaming. Every piece comes out the same tenderness because the sealed bag eliminates the hot-spot problem of an oven.
- Toss roots with butter or olive oil, salt, and herbs before bagging. The fat bastes the vegetables continuously during cooking and the flavors infuse rather than evaporating.
- Cut all pieces to the same size (about 1 inch) for consistent results. Mixed sizes mean some pieces are mushy while others are still crunchy.
- After sous vide, finish on a sheet pan under the broiler or in a hot skillet for caramelized edges. The bath gives you evenly tender interiors; the heat gives you the crispy exterior.
- Anti-tip: do not cook root vegetables above 190°F for more than 2 hours. They break down quickly at high temperatures and turn to mush. The 183°–185°F window gives tenderness without collapse.
