Ingredients
Makes 4 servings. Each ingredient is labelled with its FODMAP status at this quantity.
- High FODMAP
2 x 400 g cans chickpeas, drained and rinsed well
Low FODMAP only at 1/4 cup (42 g) drained. At the quantity used here this is a GOS-containing dish by design.
- Low FODMAP
400 g baby potatoes, halved
Potato is FODMAP-free at any portion.
- Portion-dependent
260 g courgette, cut into thick half-moons
Low FODMAP at 65 g per serve.
- Portion-dependent
300 g red bell pepper, cut into wide strips
Low FODMAP at 75 g per serve.
- Low FODMAP
2 carrots, cut into batons
- Low FODMAP
4 tbsp olive oil
- Low FODMAP
2 tbsp garlic-infused olive oil
- Low FODMAP
2 tbsp fresh rosemary, chopped
- Low FODMAP
2 tsp smoked paprika
Plain paprika only — many spice blends and "seasoned" paprikas include garlic powder.
- Low FODMAP
1 lemon, zested and juiced
- Portion-dependent
160 g feta, crumbled
Low FODMAP at 40 g per serve.
- Low FODMAP
to taste salt and black pepper
What the labels mean
- Low FODMAPSafe at the serving size listed.
- Portion-dependentLow FODMAP only up to the serving size listed — larger servings stack.
- High FODMAPAvoid during elimination. Save for a structured reintroduction challenge.
Method
Step 1: Heat the oven to 200°C / 400°F fan. Put the potatoes and carrots on a large tray with half the olive oil, season, and roast for 15 minutes on their own — they need the head start that the softer vegetables do not.
Step 2: Meanwhile, dry the drained chickpeas thoroughly on a tea towel. Wet chickpeas steam and stay soft; dry ones blister and crisp, which is most of the pleasure of this dish.
Step 3: Add the chickpeas, courgette and red pepper to the tray with the remaining olive oil, the rosemary and the smoked paprika. Toss everything together and spread it into a single layer, using two trays if it is crowded.
Step 4: Roast for a further 25 minutes, turning once halfway, until the potatoes are tender, the peppers have caught colour at the edges and some of the chickpeas have split and gone crisp.
Step 5: Take the tray out and immediately dress it with the garlic-infused oil, the lemon zest and juice. Adding the acid off the heat keeps it bright rather than cooking it flat.
Step 6: Scatter the feta over the hot tray so it softens without melting, and serve directly from it.
Notes and swaps
- Rinse the chickpeas properly under running water. A meaningful amount of the GOS leaches into the canning liquid, so draining and rinsing genuinely lowers the dose — it does not make the dish elimination-safe, but the difference is real.
- If you are still in elimination, this works with one can instead of two, which brings each serving to about 1/4 cup and inside the limit. Add 200 g more potato to make up the volume.
- Do not skip drying the chickpeas. It is the single difference between crisp and mealy.
Almost every low-FODMAP recipe you will find, on this site included, is written for the elimination phase. That makes sense — elimination is the hardest part, the part with the most rules, and the part where people most need help.
It also means the recipes quietly stop being useful at exactly the moment the protocol is working.
This one is not elimination-safe
Stated plainly, because the whole point of the recipe is that it sits on the other side of a line.
Canned chickpeas are low FODMAP at 1/4 cup drained — 42 g, which is about two heaped tablespoons. This dish puts roughly 120 g on each plate. That is a genuine dose of galacto-oligosaccharides, and if you are six weeks into elimination it will probably cause symptoms.
If you have completed a GOS challenge and tolerated it, it will probably not. That is the entire purpose of the reintroduction phase, and this is what the payoff is supposed to look like.
Why it matters that the payoff exists
The most common way this diet goes wrong is that people finish elimination, feel better, and never reintroduce anything. Restriction is uncomfortable but it is legible — you know what to do. Reintroduction means deliberately eating something that might make you feel unwell, on purpose, to gather information.
Given the choice, plenty of people simply stay in elimination. The consequences are real: a needlessly narrow diet, reduced fibre and dietary diversity, measurable changes to the gut microbiome, and for some people a slide into genuinely disordered eating around food.
The long-term goal was never a permanently restricted diet. It was the widest diet your gut will tolerate, which for most people is considerably wider than the elimination phase.
A recipe like this is what that looks like on a plate.
If you are not there yet
Use one can instead of two.
That brings each serving to about 1/4 cup of chickpeas, inside the elimination threshold, and everything else on the tray is already safe at these quantities — courgette at 65 g per serve, red pepper at 75 g, feta at 40 g, potato and carrot unrestricted. Add 200 g more baby potatoes to make up the bulk and the dish works exactly the same way.
Then come back to the full version when you have earned it.
Rinsing is worth doing properly
GOS are water-soluble, and a meaningful fraction of what is in a can of chickpeas has leached into the liquid around them.
Draining and then rinsing under running water for a good thirty seconds lowers the dose measurably. It is not a trick that makes a high-GOS portion into a low one, and it should not be treated as one. But it is free, and the difference is not trivial.
