Instructions:

1. Preheat the Oven: Preheat your oven to 375°F (190°C).

2. Prepare the Ingredients:
- Potatoes: Peel the potatoes and slice them thinly, about ⅛ inch thick, using a mandolin or a sharp knife.
- Bacon: Cook the bacon strips in a skillet over medium heat until they're crispy. Once done, drain them on paper towels and crumble them into smaller pieces.

3. Prepare the Cream Mixture:
- In a mixing bowl, combine the heavy whipping cream, milk, and ground nutmeg. Mix until evenly combined.

4. Assemble the Gratin:
- Grease a baking dish (around 9x13 inches) with butter or non-stick spray.
- Arrange a layer of potato slices at the bottom of the dish.
- Sprinkle some crumbled bacon over the potato layer.
- Repeat the layers, alternating between potatoes and bacon, until you’ve used all the ingredients, finishing with a layer of potatoes on top.

5. Pour the Cream Mixture:
- Pour the cream mixture evenly over the layered potatoes and bacon. Gently press down the potatoes with a spatula to submerge them in the liquid.

6. Cook the Gratin:
- Cover the baking dish with aluminum foil and place it in the preheated oven.
- Bake for 45 minutes. After this time, remove the foil and bake for an additional 15-20 minutes, or until the top is golden brown and the potatoes are tender when pierced with a fork.

7. Serve:
- Allow the gratin to rest for about 10 minutes before serving. This allows the flavors to meld and makes it easier to slice.

This Potato & bacon gratin is sure to become a family favorite with its creamy texture, savory flavors, and satisfying crunch. Serve it as a hearty side dish or a main course, and enjoy the rich, comforting tastes with every bite.

Cooking Tips:

- Choose the Right Potatoes: Yukon gold or russet potatoes work best for this recipe due to their starch content and ability to hold their shape while baking.

- Cook Bacon Until Crispy: To ensure the bacon adds a nice crunch to your gratin, cook the bacon strips until they are crispy but not burnt, and drain excess fat.

- Season Each Layer: For the best flavor, season each layer of potatoes with a pinch of salt, pepper, and a little nutmeg before adding the creamy mixture.

- Even Slicing: Use a mandoline slicer or a sharp knife to slice the potatoes evenly. This ensures they cook uniformly and the gratin has a consistent texture throughout.

- Cover Initially: Cover the gratin with foil for the first half of the baking time to prevent the top from browning too quickly. Remove the foil for the remainder to allow a golden, crispy crust to form.

- Rest Before Serving: Allow the gratin to rest for about 10-15 minutes after baking. This will help the layers set and make it easier to serve.
