Browned Butter Sweet Potato Casserole | Cooking Classy

This sweet potato dish has the best of everything and just the right amount of contrast with it’s creamy sweet potatoes, gooey melty marshmallows and that finishing crisp you get from the cornflakes and crunchy pecans. This casserole is heavenly. Who know the word casserole and heavenly could ever go together in the same sentence but it just does with this one. Try it and see for yourself! It might just become a family favorite for your family too!

For make ahead you can prepare the sweet potato portion the day before and refrigerate but wait until the following day to add the butter to the topping and wait to add the topping to the casserole until you’re just ready to bake and serve so it doesn’t go stale.

Yield: 12 servings


Sweet Potatoes

  • 5 lbs sweet potatoes
  • 1/2 cup (113g) salted butter, diced into 1-inch pieces
  • 1/2 cup (105g) granulated sugar
  • 1/4 cup (55g) packed light-brown sugar
  • 1/4 tsp salt
  • 3 large eggs
  • 1/3 cup (80ml) milk (anything but skim)


  • 2 cups (128g) crushed corn flakes (begin with about 4 1/2 cups and crush to 2 cups)
  • 1/2 cup (54g) chopped pecans
  • 1/4 cup (55g) packed light-brown sugar
  • 3 Tbsp (42g) salted butter, diced into 1-inch pieces
  • 3 cups (148g) miniature marshmallows


  1. Preheat oven to 400 degrees. Pierce each sweet potato several times with a fork and transfer to a rimmed cookie sheet. Bake about 1 hour, or until very tender when pierced with a fork. Meanwhile melt 1/2 cup butter in a medium saucepan over medium heat and allow to brown, swirling pan occasionally.
  2. Remove potatoes from oven and reduce oven temperature to 350. Cut each in half and scoop out flesh into a large mixing bowl. Mash potatoes with a potato masher. Pour in 1/2 cup browned butter, using a rubber spatula to scrape excess butter from pan, add granulated sugar, 1/4 cup light-brown sugar and salt then using an electric hand mixer set on low speed, blend together until well combine. Add in eggs and mix until well blended, then pour in milk and mix until well blended. Pour mixture into a buttered 13 x 9 baking dish and spread into an even layer.
  3. Brown remaining 3 Tbsp butter in a saucepan. Pour crushed cornflakes into a mixing bowl, along with chopped pecans and 1/4 cup light-brown sugar and mix to combine. Pour browned butter over mixture and toss to evenly coat. Spread mixture into diagonal rows over mashed sweet potato mixture leaving about a 1 1/2-inch gap between rows. Bake in preheated oven (350 degrees) for 30 minutes (if it's browning too much near the end you can tent with foil if needed). Remove from oven and rest 5 minutes, then spread marshmallows between rows of corn flake topping. Return to oven and bake until marshmallows are melty and lightly golden if desired about 5 - 10 minutes (I didn't brown mine much because I like the contrast of color between the white of the marshmallow and golden brown of the corn flake topping). Serve warm. Store in refrigerator in an airtight container.
  4. Note that if you are making this in advance to refrigerate then bake the following day, don't add the corn flake topping until baking or it will become stale. Also I'd recommend placing cold casserole in cool oven and let it preheat with oven.

  • Candice Wilson: I am wanting to make this for my in-laws this Thanksgiving. They are about 40 minutes away and I was wondering your recommendations on how to transport/make in advance? Can I make and bake the entire thing right before we leave and place it in a thermal cover or would that make it all soggy? Thanks! November 12, 2016 at 8:15am Reply
