These ultra-creamy mashed potatoes are made with crème fraîche instead of heavy cream for a uniquely tangy flavor.
This recipe grew out of necessity.
Or, rather, my failure to properly inventory the fridge before Thanksgiving day.
As I went to prepare my ultimate creamy mashed potatoes, I discovered I was out of heavy cream (oh, the horror!) After two pies and a batch of homemade vanilla ice cream and one carton tossed for being well past its prime, I didn’t have a single drop of usable heavy cream left at my disposal.
Luckily, what I did have was a tub of crème fraîche.
Which, as it turns out, makes for a darn fine mashed potato (if I do say so myself).
The cultured French cream (similar to sour cream but with a richer and more nuanced flavor) gives the potatoes a slight yogurty tang that really does wonders to cut the richness. Bonus? Crème fraîche is actually lower in fat than heavy whipping cream, while producing a far creamier final product.
Proof that sometimes mistakes can turn into blessings in disguise.
Now, while you technically could use sour cream, I’d really encourage you to seek out the crème fraîche, or, better yet, make your own. Real crème fraîche has a milder, less sour flavor, plus a slightly higher fat content than sour cream (30% vs 20%) which results in a creamier final product. It also doesn’t have many of the stabilizers and thickeners that many American sour cream brands add to thicken their product.
Tip for ultra-creamy mashed potatoes: use a food mill. Bonus: you don’t even have to peel the potatoes (because we all hate peeling potatoes). Just cut into chunks, boil until tender, and run through the food mill. The mill will essentially do the same job as a potato ricer, while removing the skins at same time.
Once the potatoes are milled, return them to the cooking pot on the still warm burner and add the butter. The residual heat from the pan will steam off any leftover moisture. Adding the butter first (before cream or in this case, crème fraîche, will prevent your potatoes from getting gluey).
If you’re wanting to make your mashed potatoes ahead of time, rewarm them on the stovetop, adding in a bit more butter, milk, or cream (reheated potatoes are never as creamy, so I find I have to add more liquid to get them back to the ideal consistency). You could also oven bake them in a casserole dish and serve them as twice-baked potatoes instead (which, while not as creamy, is much easier to manage timing-wise if you’re cooking for a large crowd!)
Unsure about mashed potato serving sizes? The general rule is 1/3-1/2 pound of potatoes per person. This recipe calls for 2 pounds, which would make for 4 generous or 6 smaller servings (if you have multiple side dishes you can probably count on the smaller amount).
