Ingredients:

6 potatoes
1200g
1/2 cauliflower
450g
1 cup heavy whipping cream
230g
2 tsp mustard
10g
1/2 cup mozzarella cheese
60g

Instructions:

1. Preheat the Oven: Preheat your oven to 375°F (190°C).
2. Prepare the Vegetables:
- Peel the potatoes and slice them thinly (about 1/8 inch thick) using a sharp knife or mandolin.
- Cut the cauliflower into small florets.
3. Blanch the Vegetables:
- Bring a large pot of salted water to a boil.
- Add the potato slices and cauliflower florets to the boiling water and cook for about 5 minutes, until slightly tender.
- Drain the vegetables well and set aside.
4. Prepare the Cream Mixture:
- In a mixing bowl, combine the heavy whipping cream with the mustard.
- Season with salt and pepper to taste. Mix well.
5. Assemble the Gratin:
- Grease a large baking dish with butter or non-stick cooking spray.
- Layer half of the potato slices evenly on the bottom of the dish.
- Spread half of the cauliflower florets over the potatoes.
- Pour half of the cream mixture over the vegetables.
- Repeat with another layer of potatoes, cauliflower, and the remaining cream mixture.
6. Add the Cheese:
- Sprinkle the grated mozzarella cheese evenly over the top of the assembled gratin.
7. Bake:
- Cover the baking dish with aluminum foil and place it in the preheated oven.
- Bake for 30 minutes.
- Remove the foil and bake for an additional 20-25 minutes, or until the potatoes and cauliflower are tender and the top is golden and bubbly.
8. Serve:
- Remove the gratin from the oven and let it cool for a few minutes.
- Garnish with chopped fresh herbs if desired.
- Serve warm and enjoy!

Tips:

- Use a mandoline to slice the potatoes evenly for a consistent texture and cooking time.

- Blanch the cauliflower briefly before adding it to the dish to ensure it cooks through completely in the oven.

- Mix the heavy whipping cream with the mustard well before pouring it over the vegetables to ensure even distribution.

- Cover the dish with foil for the first half of the baking time to prevent the cheese from burning.

- Let the gratin rest for a few minutes after baking to allow the flavors to meld and the dish to set.

Potato and cauliflower gratin is an easy-to-make, flavorful dish that elevates the simple ingredients of potatoes and cauliflower into something truly special.
