WHY TO LIMIT IT ON KETO
- Fits limited use: 50–75g servings keep carbs manageable
- Naturally sweet—satisfies cravings in small amounts
- Nutrient-dense (vitamin A, potassium) for the carb cost
- Versatile: roast, mash, purée, or spiralize for variety
PREPARATION SUGGESTIONS
ROASTED (SMALL PORTION)
Cube, toss with olive-oil, salt, and a pinch of warm spices; roast at 425°F (220°C) for 25–30 min. Limit to ~50g per serving.
SOUP WITH CREAM
Roast, then blend with chicken broth and heavy-cream. Rich and comforting—serve in small bowls.
MASHED AS SIDE
Roast until tender; mash with butter and a splash of cream. Keep to ~50–75g alongside protein.
SPIRALIZED
Spiralize the neck; sauté briefly in butter or ghee. Higher carb than zucchini—use sparingly.
