Vegetables aren't the enemy on keto — they're the foundation. But not every vegetable fits. Here's a practical ranked guide.

The 'eat freely' tier (under 3 g net per cup)

  • Spinach — 0.4 g net raw, 4 g cooked
  • Lettuce (all varieties) — 1 g net
  • Arugula — 0.4 g net
  • Bok choy — 1 g net
  • Cucumber — 2 g net
  • Celery — 1.5 g net
  • Zucchini — 2.5 g net
  • Asparagus — 2 g net
  • Radishes — 2 g net

The 'measure it' tier (3–6 g net per cup)

  • Broccoli — 4 g net
  • Cauliflower — 3 g net
  • Green beans — 4 g net
  • Mushrooms — 2–3 g net (button); higher for shiitake
  • Bell pepper — 4 g net (green); higher for red/yellow
  • Cabbage — 3 g net raw
  • Brussels sprouts — 5 g net
  • Kale — 6 g net cooked

The 'small portion only' tier (6–10 g net per cup)

  • Butternut squash — 15 g net (limit to 1/4 cup)
  • Carrots — 8 g net (grated over salad, not as a side)
  • Onions — 12 g net per cup (use small amounts for flavor)
  • Beets — 13 g net (rare inclusion)

Skip on strict keto

  • Potatoes — starchy
  • Sweet potatoes — starchy
  • Corn — a grain, not a vegetable
  • Peas — high carb
  • Parsnips — starchy

Storage tips

  • Leafy greens — wash, spin dry, roll in paper towels inside a container
  • Broccoli/cauliflower — dry in fridge, use within 5 days
  • Zucchini — countertop 2 days, fridge 5 days (no washing until use)
  • Herbs — wrap in damp paper towel inside a sealed bag

Frequently asked questions

Are pickles keto?

Dill pickles yes. Bread-and-butter pickles no.

Can I have onion?

Yes, in flavoring amounts. A quarter of a small onion in a sauté is negligible; a full raw onion on a salad is not.
