Ingredients
- Aol Food
- 5 oz applewood-smoked bacon diced
- 1 c chopped onion
- 2 garlic cloves finely chopped
- 2 c heavy whipping cream

- 1 tsp kosher salt

- 2 c (about 8 ounces) grated Gruyère cheese
Preparation
Step 1
Preheat the oven to 350°F. Sauté the bacon in a heavy large sauté pan over medium heat until just golden brown about 7 minutes. Using a slotted spoon transfer the bacon to a bowl leaving the bacon drippings in the pan.
Add the onions to the same pan and sauté until they are translucent about 4 minutes. Add the garlic and sauté until the onions are pale golden stirring often about 2 minutes. Add the cream milk and thyme. Bring the mixture to a simmer. Set aside.
Meanwhile using a mandoline slicer or a very sharp knife cut the potatoes crosswise into 1/8-inch-thick slices. Toss the potato slices in a large mixing bowl with the warm cream mixture to coat. Add the salt and black pepper and toss again.
Neatly arrange one-fourth of the potato mixture in a 13x9x2-inch baking dish or other 2-quart baking dish. Sprinkle 1/2 cup of the cheese over. Repeat layering the remaining potato mixture and cheese 3 more times.
Cover with foil and bake for 40 minutes. Remove the foil and bake until the potatoes are tender and golden brown on top about 20 minutes. You should be able to gently poke a fork through the potatoes when finished. Let stand for 10 minutes to cool slightly then serve.
