Why this Dauphinoise potatoes gratin is so easy
This is an easy potatoes gratin recipe because instead of messing with pre-boiling the potatoes in milk, draining them and then putting them on the dish to grill, I cook the potatoes directly in the serving dish using the microwave.
I use the right amount of milk to cook the potatoes and make them creamy. Not too much liquid, not too much dry. Just perfect!
I cook the potatoes earlier, top them with the cheese and grill it just before serving it.
The ingredients are:
- 4 medium potatoes (500 gr)
- 1 onion
- 1 garlic clove
- 1 teaspoon of thyme
- 1 teaspoon of minced fresh sage
- 1 cup grated gruyere cheese (70 gr)
- ½ cup of skimmed milk (100 gr)
- ¼ cup of cream (50 ml)
- 1 pinch of nutmeg
- Salt and pepper
Pre-cooking the potatoes in the microwave
- Peel and clean the potatoes and the onion and cut them into thin slices, best with an electric slicer.
- Rub the garlic clove inside a baking dish that can be used in a microwave and butter abundantly.
- Layer the potatoes and the onion, seasoning with salt and pepper and sprinkling with sage, thyme and some cheese.
- Keep adding layers until you reach the top.
- Pour over the milk and the cream which have been flavoured with some nutmeg.
- Cook in the microwave at the highest level for 15 minutes. Let it rest for 5 more minutes in the microwave once it is done.
- At the last minute, just before serving it, add the remaining Gruyere cheese generously to cover the potatoes, and grill it in the oven.
- The Gratin Dauphinoise is ready to be served with your favourite main course.
Tips
- Cut the onions and the potatoes into thin slices, best with an electric slicer
- Use exactly the amount of milk and cream from the recipe
- Cook in the microwave at the highest level for exactly 15 minutes
- Put a baking tray under the gratin to collect any possible spill of cream and milk
- Top with plenty of cheese
- Serve warm
