Preheat Oven: Preheat your oven to 375°F (190°C). Grease a 12-cup muffin tin with olive oil
Prepare Potatoes: Wash and thinly slice the potatoes using a mandolin or a sharp knife. Make sure the slices are uniform for even cooking
Cheese Mixture: In a bowl, combine the Gruyère and Parmesan cheeses. Set aside
Herb Cream: In a separate bowl, mix together the heavy cream, minced garlic, thyme, and rosemary. Add salt and pepper to taste
Layering: Place a potato slice at the bottom of each muffin cup. Sprinkle a little of the cheese mixture on top, followed by a teaspoon of the herb cream. Repeat the layers until the muffin cups are filled, ending with a layer of cheese
Bake: Place the muffin tin in the preheated oven and bake for 45 minutes, or until the potatoes are tender and the tops are golden brown
Cool and Serve: Allow the stacks to cool for 5 minutes before removing them from the muffin tin. Serve warm and enjoy your gourmet Cheesy Potato Stacks!
Notes
Slice It Right: Use a mandolin slicer for those potatoes if you can. It'll give you super even slices, which means they'll cook at the same rate. No one wants a stack with some mushy and some crunchy layers!
Cheese Grating Hack: Freeze your cheese block for about 15 minutes before grating. It makes the grating process a breeze, especially for softer cheeses like Gruyère.
Layer Like a Pro: Don't just slap those ingredients in the muffin tin. Take a minute to neatly layer each slice and evenly distribute the cheese and herb cream. Presentation points, people!
Creamy Dreamy: When mixing your herb cream, give it a good whisk to make sure the garlic and herbs are well-distributed. You want every bite to be a flavor bomb.
Don't Skimp on Seasoning: Potatoes love salt. Don't be shy—season each layer as you go. It makes a world of difference.
Check as You Go: Ovens can be finicky. Start checking for doneness around the 35-minute mark. A fork should easily slide through the layers when they're done.
Let It Rest: I know it's hard, but let those stacks sit for about 5 minutes after you take them out of the oven. It makes them easier to remove from the tin and lets the flavors meld a bit more.
The Golden Touch: For that extra golden top, you can broil the stacks for a minute or two after baking. Just keep an eye on them so they don't go from golden to burnt!
