If you've never cooked with Jerusalem artichokes, consider this your introduction to arguably the most powerful prebiotic vegetable out there, up to 19 grams of inulin per 100 grams. One honest heads-up: if you're new to them, start with a small portion. That much inulin can cause some noticeable fermentation while your gut bacteria adjust, which is completely normal and settles down with regular, gradual exposure.
Ingredients
- 500g Jerusalem artichokes (sunchokes), scrubbed and halved or quartered
- 4 garlic cloves, lightly crushed
- 3 tbsp olive oil
- 1 tbsp fresh thyme or rosemary
- 1 tsp lemon zest
- Salt and black pepper
- Fresh parsley and lemon juice to serve
Instructions
- Preheat oven to 200C. No need to peel — the skin is edible and adds fiber.
- Toss artichokes and garlic with olive oil, thyme, lemon zest, salt, and pepper. Spread in a single layer on a baking sheet.
- Roast 30-35 minutes, turning once halfway, until golden and tender throughout.
- Finish with a squeeze of lemon juice and fresh parsley before serving.

Why This Is Good for Your Gut
Jerusalem artichokes contain up to 19g of inulin per 100g — one of the highest concentrations of any food. Inulin is fermented by gut bacteria to produce butyrate, the primary fuel for colon cells. Research specifically links inulin consumption to significant increases in Bifidobacterium populations. Garlic adds further inulin for a powerfully prebiotic combination.
Start small here and build up slowly. Your gut bacteria adjust, and after a few tries you'll handle a full portion just fine.
