I CAN’T BELIEVE I DIDN’T THINK OF MAKING SWEET POTATO DAUPHINOISE BEFORE. AFTER ALL, REGULAR POTATO DAUPHINOISE IS ONE OF MY FAVORITE HOLIDAY DISHES. BAKED IN A HEAVY CREAM, GARLIC AND PARMESAN SAUCE THIS IS ONE SIDE DISH THAT SHOULD BE ON YOUR MENU!
I just had another thought, how amazing would it be to use purple potatoes! Those might be showing up here soon, but for now, let’s talk about these slow baked sweet potatoes. Each layer of sweet potato is seasoned, sprinkled with grated Parmesan and then doused in a creamy garlic sauce. Bake them in the oven for about an hour and a half and you’ll end up with a pan full of cheesy, creamy awesomeness.
Because sweet potatoes can be really weird shapes, you’ll end up with some slices being way smaller than the pieces cut more towards the center of the potato. Don’t worry, they’ll all come together in the end but when you buy them try and pick the fatter ones rather than the long skinny kind.
I rarely peel my potatoes after reading how nutritional the skin can be and really, who likes to peel spuds? Even the fries at In N Out Burger are hand cut and covered in the skin. I feel bad for my Mom, I remember watching her peel loads of potatoes to feed us when I was a kid. Dang it, if I had just told her to keep the skin! Give them a good rinse under some running water and start slicing. How thick or thin they are will determine your cooking time, to check if they’re done just poke them with a sharp knife and you shouldn’t feel any resistance. You could use a mandolin but yikes, those things should come with a warning and free training, be careful.
