Savory Sweet Potato Casserole Recipe

Sweet potatoes are truly one of my favorite foods and I generally prefer them prepared in a savory way. The typical sweet potato casserole,the one  laden with brown sugar and topped with marshmallows that’s so popular for Thanksgiving, doesn’t really appeal to me. But I love for sweet potatoes to be a part of our Thanksgiving meal. So instead I thought I’d try a savory sweet potato casserole. Fresh herbs, bacon, and onions give this casserole lots of wonderful flavor. It’s a wonderful addition to a holiday table.

How To Make

First I baked 4 large sweet potatoes in the oven until very soft, let them cool slightly, peeled off the skin, and mashed the pulp with a fork. I measured out 4 packed cups into my mixing bowl along with 2 tablespoons butter, 1/3 cup heavy cream, an egg, about 1/4 teaspoon cayenne pepper, and some salt and black pepper. I beat everything just long enough to get it all smooth.

While the sweet potatoes were baking, I cooked some bacon, crumbled it, and set it aside. I used the bacon grease to cook a chopped onion. Is there anything better than the smell of onion cooking in bacon grease?  Just before removing the onion from the heat, I added some fresh thyme and rosemary and immediately my kitchen smelled heavenly.

I stirred the onion into the sweet potato mixture along with half the bacon and 1/2 cup shredded gruyere cheese. Into a casserole dish it went. I then added a little more shredded Gruyere on top along with some Panko crumbs and chopped pecans mixed with melted butter.

Thirty minutes in the oven and a quick broil to brown the Panko crumbs and it was ready to be served. I sprinkled the remaining bacon on just before serving. You can never have enough bacon.  ๐Ÿ™‚

Wonderfully smooth, creamy, savory and just a little spicy, serve Savory Sweet Potato Casserole for Thanksgiving side dish and save your sweet tooth for dessert!
