Are you a Costco shopper? I am, mainly because as my kids get bigger, so do their appetites. I know sometimes we don’t *need* an industrial sized vat of something, but then I’m amazed at how quickly we blow through it. Everyone in my family is a big dairy eater, so we often stock up on dairy products at Costco, including cheese. The two pound package of BelGioioso Mild Provolone is one of our favorites because we can use it in so many dishes. I made this Provolone, Mushroom and Potato Gratin using #MyFavoriteProv, BelGioioso, and it’s my newest crave-worthy side dish that would be impressive for entertaining as well as a unique side dish for your Thanksgiving table.
This gratin is filled with layers of thinly sliced potatoes, mushrooms, flavorful Provolone cheese, seasoned with thyme and then topped off with cream and a sprinkle of parmesan.
A couple of things I learned when making this gratin:
1) Stick with Russet potatoes. Don’t try to sub in Yukon Golds. Their water content is too high, and the end result is a soupy mess.
2) A recipe is only as good as the ingredients you use, so don’t try to “healthify” this with milk or less cheese and expect the same results. It’s not going to happen.
Because the flavors in this gratin shine through, I used heavy cream and BelGioioso Mild Provolone cheese. Made in Wisconsin, this cheese is aged for 60 days to enhance its flavor and is a top-notch melting cheese. Makes it easy to see why it’s a match made in heaven, right?
Using quality ingredients doesn’t have to mean you’ll break the bank, though. Being able to buy the two pound package of BelGioioso at Costco is ideal for dairy lovers like us. It may sound like a lot, but Provolone is really versatile (Look for an easy lasagna recipe using Provolone just in time for Halloween!), and I’m always amazed at how quickly it goes in our house. No worries, though; I understand if your family doesn’t consume the mass quantities of cheese that mine does. Fortunately BelGioioso Mild Provolone is available at retailers everywhere so you can buy the amount that’s right for your family.
But I encourage you to buy a little more than normal, because you’re going to want to make this Provolone, Mushroom and Potato Gratin more than once.
