Truffle and Jambon Croquettes

Truffle and Jambon Croquettes

I hope you ate a lot at Thanksgiving! I’m not sure about you, but I tend to get full after a bite of each dish. That means leftovers. The best part of leftovers is turning them into other delicious dishes. Do you have loads of mashed potatoes? Then this recipe is for you!


The word “croquette” is based on the French word “croquer” which means to bite or to crunch. The modern version of croquette was created by Auguste Escoffier in France in 1898. Croquettes are typically filled with potatoes and meat, dredged in egg, breaded, and then fried. The filling may differ but potatoes are consistent.

The creaminess of the filling comes from a sauce. In my recipe, I rely on béchamel to give the croquettes that signature creaminess.

Truffle Butter and Diced Jambon

Fabrique Délices is the place to go for truffle butter! I’ve been buying their truffle butter for years now because there is so much truffle in their products. The butter is speckled with bits of truffle so you know it’s full of the good stuff. There are two types of truffle butter: black and white. The butters are interchangeable with some minor differences. Black truffle is more aromatic and white truffle is more delicate. This recipe uses both but you can definitely just use one.

Fabrique Délices also sells a wide range of meats. Their pâtés and mousses are perfect on any cheese and charcuterie board. Their diced jambon de Paris is the best for these croquettes. First off, they’re already diced and ready to go. Second, they add the perfect pop of salinity and texture.

Freeze Them!

Don’t feel pressured to eat these all at once. Unfried croquettes can be frozen for up to one month! Pull them out from the freezer and straight into the fryer – no need to thaw!
