Cauliflower Chickpea Gratin With Tomato Layer + Roasted Chickpea Side
A lighter baked gratin for two: tender cauliflower and chickpeas with a single layer of sliced tomatoes, topped with a reduced‑fat cheese sauce, served with a side of crisp roasted chickpeas.

Ingredients
- 1 medium head cauliflower (≈600–700 g), cut into florets
- 1 can (400 g) chickpeas, rinsed and drained — split: 200 g for the gratin, 200 g for roasting
- 2 medium tomatoes, sliced (about 5 mm thick)
- 150 ml low‑fat crème fraîche OR 120 g plain low‑fat yogurt + 80 ml skim milk (option)
- 100 g reduced‑fat cheddar, grated (reserve a small pinch for the roasted chickpeas)
- 1 tsp Dijon mustard
- Pinch nutmeg
- Salt and freshly ground black pepper
- 1 tbsp olive oil for the baking dish
- 1 tbsp olive oil for roasting chickpeas
- 1/2 tsp dried thyme or oregano (optional, mild)
Instructions
- Preheat oven to 200°C (400°F).
- Steam or simmer cauliflower florets 6–8 minutes until just tender; drain very well and let steam off in a colander.
- Pat chickpeas dry. Reserve 200 g for the gratin and place the remaining 200 g in a bowl for roasting; toss the roasting portion with 1 tbsp olive oil, salt, pepper and a pinch of the grated cheese (optional).
- Lightly oil a small ovenproof baking dish for two. Spread cauliflower evenly, scatter the 200 g chickpeas over it, then arrange tomato slices in a single layer on top. Sprinkle thyme or oregano if using.
- Mix low‑fat crème fraîche (or yogurt + milk), Dijon mustard, nutmeg, salt and pepper until smooth. Stir in about two‑thirds of the grated cheese.
- Pour the sauce evenly over the layered vegetables and tomatoes; sprinkle remaining cheese on top.
- Put the gratin in the oven and the chickpeas for roasting on a separate tray. Roast chickpeas 20–25 minutes, shaking once, until golden and crisp. Bake gratin 20–25 minutes until bubbling and golden; optionally grill 1–2 minutes to brown the top.
- Rest the gratin 5 minutes. Serve each portion with a small bowl or spoonful of roasted chickpeas for crunch.
Notes
- Ensure cauliflower and chickpeas are well drained to avoid a watery gratin.
- Tomato slices should be even so they form a single consistent layer.
- Low‑fat crème fraîche or yogurt keeps the dish lighter while keeping creaminess.
- Roasted chickpeas can be made ahead and re‑crisped in a hot oven 5–7 minutes before serving.
