Is there anything better than a crispy, cheesy stack of sweet potatoes? Yes. My Gremolata Sweet Potato Stacks get a flavor boost from gremolata flavored olive oil.

These potatoes are like potato gratin stacks…soft in the middle, filled with cheese and crispy on the edges. They are packed with flavor too. I used both dry and fresh herbs, plus both butter and gremolata infused olive oil to bump up the flavor. I also used two types of cheese in this dish, Parmesan and Gruyere. NOTE: you can use regular plain olive oil if you don’t have the specialty oil.

Muffin tin potatoes have been around for a long time and you can play with the seasoning you use, the herbs you use, and of course, the types of cheese. I do like using a cheese that is a little melty…it helps keep the stacks “stuck together”. LOL (Like I needed another reason to add cheese!!!)

You can also use plain Idaho potatoes for these…love them! I was making this dish in preparation for Thanksgiving so wanted to use sweet potatoes…both work.

To get started, preheat your oven to 400 degrees F. Spray your 6 cup muffin tin with cooking spray. NOTE: you can easily double or triple this recipe with equal amounts of ingredients for each increase.

Next, peel your sweet potatoes and using a mandoline, slice into 1/8 inch slices. You want them thin but not so thin that you can see through them or they’ll kind of fall apart. No mandoline? No problem. Use a very sharp knife a thinly slice your potatoes. Put all the potatoes in a large bowl.

Next, add all the remaining ingredients except for the flaky salt. Add the melted butter-oil-garlic mixture. Toss everything really well so every potato slices is coated in the mix and the cheese and seasoning is evenly distributed among all the slices. That chese helps you stacks stay together so, be sure every is coated.

I use thongs to pull together a bunch of potatoes and stack them in each cup. Straighten them up with your thongs so they are stacked. If you have any butter/oil or cheese left in the bowl, spoon it up and put it over the potato stacks. Use every single potato and don’t worry if they are really high and over the rim of the cups. They do shrink when baked.

Cover with foil. TIP: spray the side that will be touching the potatoes with cooking spray. It will help keep the potato stacks from sticking to the foil. Put in the oven and roast for 40 minutes. Uncover the pan and roast for another 20 minutes.

Remove from the oven and run a knife around the edges of the stacks to loosen them from the sides. I find that a tablespoon is the best way to dig them out of the cups and to plate them. Once plated, sprinkle with some flaky salt and enjoy.
