WHY IT'S NOT KETO-FRIENDLY
- Not suitable for ketogenic diets due to high net carbs (~15–16g/100g)
- This item contains the nutrients or compounds listed above; evidence for specific health outcomes depends on dose, preparation, and individual context.
- Typical add-ins (milk, cream) add calories without reducing carbs
- Easy to overeat because of soft texture and comfort-food appeal
- Better replaced with low-carb ‘mash’ substitutes (cauliflower/turnip)
- If consumed off-plan, keep portions very small and pair with protein/fat
PREPARATION SUGGESTIONS
CLASSIC (NON-KETO)
Mash boiled potatoes with butter and heavy-cream; season with salt, pepper, and garlic. Reserve for non-keto days.
CAULIFLOWER MASH (KETO SWAP)
Steam cauliflower florets; blend with butter, sour-cream, and garlic until creamy.
RUTABAGA–CAULIFLOWER BLEND
Simmer rutabaga and cauliflower; mash with parmesan-cheese and olive-oil for a lower-carb ‘potato’ vibe.
TURNIP MASH
Boil turnips until tender; mash with butter and chives for a sharp, potato-like side.
LOADED KETO MASH
Top cauliflower mash with bacon, cheddar-cheese, and sour-cream for a satiating side.
HERB–GARLIC OLIVE OIL MASH
Blend cauliflower with olive-oil, roasted garlic, and parsley for a dairy-free option.
