WHY IT'S NOT KETO-FRIENDLY
- Not keto-friendly: High net carbs (~15.4g/100g) crowd out your daily limit
- Even small portions add up: 50g still delivers ~7.7g net carbs
- Better alternatives exist: Cauliflower, turnips, radishes mimic texture with far fewer carbs
- Easy to overeat: Can disrupt ketosis due to glycemic load
- Poor keto trade-off: Uses carb budget better spent on nutrient-dense low-carb veg

PREPARATION SUGGESTIONS
SKIP POTATOES - USE CAULIFLOWER INSTEAD
Replace mashed potatoes with mashed cauliflower. Steam cauliflower, mash with butter, cream cheese, and garlic for a satisfying low-carb substitute.
TRY TURNIPS FOR ROASTING
Cut turnips into cubes, toss with olive oil and herbs, roast at 425°F. They develop a similar golden exterior with only ~4.6g net carbs per 100g.
RADISHES AS POTATO ALTERNATIVE
Roasted radishes lose their sharp flavor and taste remarkably similar to potatoes. Quarter and roast with butter and seasonings.
CAULIFLOWER HASH BROWNS
Grate cauliflower, squeeze out moisture, mix with egg and cheese. Pan-fry until crispy for a keto-friendly hash brown alternative.
JICAMA FRIES
Cut jicama into fry shapes, toss with oil and spices, bake at 400°F for 30–40 minutes. Crispy outside, tender inside, lower carbs.
CELERIAC MASH
Celery root (celeriac) can be boiled and mashed like potatoes with butter and cream for a flavorful low-carb side dish.
