Sweet Potato Bisque with Truffle Oil

When it comes to Thanksgiving, we’re pretty much traditionalists at my house.  Meaning the meal looks pretty much the same every year with the usual suspects.  Turkey, mashed potatoes, gravy, stuffing, green beans, sweet potatoes and homemade dinner rolls are always on the menu and typically it’s the same recipe every year.

Even though my family expects the same meal every year, that doesn’t mean that I don’t try and tweak things every now and then.  Which is exactly how this sweet potato bisque came to be.  It actually came as a result of leftover mashed sweet potatoes.

The first time I made this bisque, I used the leftover mashed sweet potatoes  to make the bisque and it was an immediate hit.  I soon realized that I didn’t need leftovers, that I could cook cubed sweet potatoes right in the stock and then puree everything together to make a silky smooth bisque.  But, by all means, if you have leftover mashed sweet potatoes, feel free to use them in this recipe.  Just stir them in along with the stock.  You’ll still want to puree the bisque to make sure you get that silky smooth texture.

What ends up making this sweet potato bisque crazy delicious is a generous drizzle of truffle oil and some buttery homemade croutons.  The earthiness of the truffle oil is a great flavor balance with the sweetness of the potatoes and the croutons give great texture and additional flavor.
