Savory Sweet Potato Casserole with Bacon and Gruyere

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 Β 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.

Savory Sweet Potato Casserole with Bacon and Gruyere

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? Β 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. Β πŸ™‚

  1. This has quickly and easily became one of our family FAVORITE sides! My mom uses it in her chicken pot pies and it is a GAME CHANGER guys!

  2. Sounds great, I will give it a try. Only my wife and I at Thanksgiving, and she hates sweet potatoes. More for me.

  3. My family hates sweet potatoes because all they have ever tasted is the nasty, overly sweet, gooey casserole served at holiday meals. I tried this for my husband and he raved. My daughter tried leftovers and now wants it for Thanksgiving. It’s easy and delicious, dosen’t get much better than that!

  4. I made it for Thanksgiving. It was very tasty and had people ask for recipe. I”m going to make with Christmas dinner. Wondering if I can make it the day before and then do the finish work with the panko etc. on Christmas Day?

  5. Do you think I could make this in the crock pot? We do a large thanksgiving that we bring our cooked dish to. I’m thinking the potatos will work, but the bread crumbs won’t brown. Any thoughts?

    1. I think you could cook it in the crockpot. Sometimes when I want crispy breadcrumbs on a crock pot dish, I brown them in a skillet with butter and then sprinkle them on top of the casserole just before serving.

  6. The recipe contains 2 different measurements for the sweet potatoes. In the description, it says that you used 4 cups. But, in the instruction section, it says 5 cups. Which is the correct amount?

    1. You want to use 5 cups of mashed sweet potato. $ large sweet potatoes should be plenty to get 5 cups of mashed. If you have extra you can freeze for another use (soup, pasta sauce, etc).

  7. I am definitely making these for Thanksgiving !! one of the guests has celiac, I found out you can substitute crushed Rice Chex for the panko crumbs !! who doesn’t love dishes flavored with bacon πŸ™‚

  8. Think I’ll try caramelizing the bacon with just a bit of brown sugar before chopping it up and sprinkling it over the sweet potatoes

  9. I also grew up with brown sugar and marshmallow sweet potatoes and always wondered why are we adding more sugar to something already sweet?!?! I love that you made them savory! You had me at bacon, gruyere and onions! My husband might even like sweet potatoes this way! This Thanksgiving, I will be signing up for bringing sweet potatoes =)

  10. I make a sweet potato casserole with pecan streusel every year, and every year I think we don’t need anything else sweet on the dinner table! I love the sound of this with the herbs and gruyere — I think I might just like this more! Definitely trying this one. πŸ™‚

  11. Sweet potatoes are one of my favorites but I don’t really dig the sweet preparations – savory all the way! Love this savory twist on a casserole!

  12. I love sweet potatoes, the only trouble is my children don’t. πŸ™ It won’t stop me though, I will make this even if it is only for me and my husband, it looks amazing and I can just imagine the taste.
