- 4 zucchinis, sliced
- 300 ml cream
- 150 g gruyère
- 2 garlic cloves
- 2 tbsp butter
- 1 pinch nutmeg
- Black pepper
- 1 tbsp olive oil
- Salt and black pepper, to taste
Method
Step 1. Preheat the oven to 200°C (390°F) and grease a baking dish.
- Heat
- Oven to temperature (about 10-15 minutes)
- Look for
- The oil shimmers and flows like water; a drop of water sizzles instantly.
- Why it matters
- Food added to a properly hot pan sears and browns instead of steaming and sticking.
- Avoid
- Adding food to a cold pan: it sticks, turns grey and soaks up oil.
Step 2. Season the zucchini and brown briefly in a hot pan with a little oil, about 5 minutes.
- Heat
- Off, no heat
- Look for
- Everything is evenly coated or just combined, with no dry pockets.
- Why it matters
- Mixing spreads salt, fat and flavour through the food so every bite tastes the same.
- Avoid
- Overmixing batters and doughs makes them tough; stop once just combined.
Step 3. Combine with the cream, gruyère and arlic cloves in the dish and mix well.
- Heat
- Off, no heat
- Look for
- Everything is evenly coated or just combined, with no dry pockets.
- Why it matters
- Mixing spreads salt, fat and flavour through the food so every bite tastes the same.
- Avoid
- Overmixing batters and doughs makes them tough; stop once just combined.
Step 4. Top with the butter and pinch nutmeg.
- Heat
- Keep the heat steady
- Look for
- The new ingredient is coated and the mixture returns to a gentle bubble.
- Why it matters
- Adding things in order lets each ingredient cook for just the right time.
- Avoid
- Dumping everything in at once: delicate items turn mushy before tougher ones are done.
Step 5. Bake for 30 minutes until bubbling and golden on top.
- Heat
- Oven at the stated temperature (check with a thermometer if you can)
- Look for
- Bubbling edges, a golden top and a rich baked smell.
- Why it matters
- Gentle, steady heat softens tough fibres and lets flavours blend without drying things out.
- Avoid
- Opening the oven door repeatedly drops the temperature. Cover loosely with foil if the top browns too fast.
Step 6. Rest for 10 minutes before slicing and serving.
- Heat
- Off, let it sit
- Look for
- Steam slows, juices settle and the dish firms up slightly.
- Why it matters
- Resting lets juices redistribute and flavours settle, and the food is easier to slice and eat.
- Avoid
- Skipping the rest: juices run out and the dish falls apart.
