Method
Step 1: Prep the Ingredients
- First things first! Peel and thinly slice the Yukon Gold potatoes. Aim for about 1/8 inch thickness. Consistent slices ensure even cooking. You can use a mandoline for this if you have one; it saves time!
Step 2: Preheat the Oven
- Preheat your oven to 350°F (175°C). This ensures your potatoes cook evenly and thoroughly.
Step 3: Grease the Baking Dish
- Take a 3-quart baking dish and rub the bottom and sides with unsalted butter. This prevents sticking and gives a lovely flavor.
Step 4: Assemble the Layers
- Spread half of the sliced potatoes in the baking dish. Season with salt, pepper, and half of the minced garlic. Sprinkle half of the grated Gruyère cheese on top of the first layer.
Step 5: Repeat the Layering
- Add the other half of the potato slices on top. Season again with salt and pepper, and then repeat with the remaining garlic and more Gruyère cheese.
Step 6: Prepare the Cream Mixture
- In a separate bowl, combine the heavy cream, full-fat milk, nutmeg, bay leaves, thyme, and Dijon mustard. Mix well. Pour the cream mixture evenly over the sliced potatoes in the baking dish.
Step 7: Bake
- Cover the dish tightly with aluminum foil. Bake for 1 hour. This allows the potatoes to warm through and start cooking.
Step 8: Remove the Foil and Add the Final Touch
- After an hour, carefully remove the foil. Sprinkle the remaining Gruyère cheese on top, and return to the oven for an additional 30 minutes, until the top is golden brown and the potatoes are tender.
Step 9: Cool and Serve
- Once baked, allow the dish to cool slightly. Remove the bay leaves and sprinkle chopped fresh chives on top for a pop of color and flavor.
Notes
e some handy tips to help you along the way:
- Slice Uniformly: Consistent thickness ensures all potatoes cook evenly. A mandoline can be a lifesaver.
- Cheese Options: If Gruyère isn’t available, use Swiss or cheddar. Just keep in mind that this will change the flavor.
- Make Ahead: You can assemble your dish a day in advance and refrigerate. Just add an extra 10-15 minutes to the cooking time.
- Don’t Rush the Baking: Although it’s tempting, allow the eyes to brown for that delicious crust.
- Serving Tip: Dauphinoise potatoes taste even better the next day. Perfect for leftovers!
