Browned Butter Sweet Potato Casserole


Have you tried this Browned Butter Sweet Potato Casserole yet? I originally shared this recipe Nov. 14, 2012 but I wanted to update the photos as well as remind everyone that this should be the only sweet potato casserole recipe you should be using this Thanksgiving :). I thought trying and sharing a different sweet potato casserole recipe but really there’s just no point. I know I can’t top this one. It is my go to every year and it’s always a crowd pleaser! I never used to care for sweet potato casserole then I added browned butter to it as well as a crisp cornflake and pecan topping and everything changed. Turn those sweet potato haters into sweet potato lovers with this recipe, seriously!

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.

Browned Butter Sweet Potato Casserole

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.

    • Laura ~ Raise Your Garden: SO agree! I mean, I’ve seen so many recipes online for sweet potatoes on Pinterest and I was trying to decide which one to make. Oh my……this visual presentation is so stimulating and gorgeous….this is what I want to bring to Thanksgiving! I love how you layered those marshmallows on top. What a showstopper!!!!

  • Chung-Ah | Damn Delicious: Oh my goodness – this is absolutely amazing! And that presentation – GORGEOUS! If I make this for Thanksgiving, I am going to get so many compliments. I thank you in advance! November 15, 2012 at 5:14pm Reply

  • Dina: i like your design. pretty! November 17, 2012 at 5:03pm Reply

  • flammie: I’m making this right now for tomorrows feast. I’m putting them back in the skins for a cute individual presentation. I can’t wait to taste it!! Question: should I bake it all off today and simply reheat tomorrow? Or prepare it but only bake tomorrow? Thanks November 21, 2012 at 12:15pm Reply

    • Jaclyn: I would recommend simply preparing it today without baking BUT leave the topping off or the corn flake topping will become stale/soggy. Refrigerate then bake it tomorrow and add corn flake topping just before baking. Also start it out in a cool oven – let it preheat with oven(basically just allowing it more time to warm). I hope that helps and I hope you have a great Thanksgiving! November 21, 2012 at 5:02pm Reply

  • dclare designs: I totally made this tonight for thanksgiving…and everyone loved it! I wasn’t even allowed to take any home, people wanted to take it home. :) this was my first time making a sweet potato dish and I thank you! Everything I have made from this site has been 100% awesome! Thank you for all you post.

    Deidre and the rest of my family are thankful :) November 23, 2012 at 12:48am Reply

    • Jaclyn: You are very welcome! I’m so glad to hear you and your family enjoyed this! I myself made it twice last week, isn’t Thanksgiving just great! Thanks so much for your kind comment! November 27, 2012 at 11:51pm Reply

  • Monique @Ambitious Kitchen: I love this Jaclyn! Omg we made a sweet potato dish yesterday and I wanted to drizzle brown butter all over it. November 23, 2012 at 11:27am Reply

  • Julie: Hi Jaclyn,

    If I double this, how long do you recommend cooking? November 30, 2012 at 8:27pm Reply

    • Jaclyn: Hi Julie, I would recommend doubling the recipe placing it in two 13×9 baking dishes, you’d likely just bake them for the same amount of time side by side. I hope you love it =)! December 2, 2012 at 11:22pm Reply

    THANKS! October 8, 2013 at 12:39pm Reply

    • Jaclyn: They are to hold the casserole together they act as a binder. Not sure how this would turn out without them? October 14, 2013 at 7:59pm Reply

  • Sandy Ward: Can the casserole be made ahead and frozen? November 11, 2013 at 10:23pm Reply

    • Jaclyn: I think that would be fine, I would just keep the topping separate until ready to bake though. And be sure it’s fully thawed before you bake it. November 16, 2013 at 9:24am Reply

  • Talia: Can I substitute almond milk for the milk? Same measurement? And I know this is blasphemy, but my boyfriend is Kosher, what’s the ratio if I do it with margarine instead. Or maybe coconut oil… because margarine is gross. November 12, 2013 at 1:14pm Reply

    • Jaclyn: Yes you could sub almond milk (I would use unsweetened) and the coconut oil would probably be fine but I would reduce it by a few tablespoons (and not brown it of course). November 15, 2013 at 7:39pm Reply

  • Mollie: Hi Jaclyn! This will be my first year cooking Thanksgiving diner (the whole thing…ek!) I can’t wait to try this recipe – it looks incredible and I absolutely love the presentation. I have a hardware question for you. Is it imperative that I use a potato masher to mash the sweet potatoes or would a fork suffice? Thanks! November 17, 2013 at 3:00pm Reply

    • Jaclyn: A fork would probably work okay it might just take a lot longer. I hope you love it if you do make it Mollie! November 17, 2013 at 9:29pm Reply

  • sadie: Hi jaclyn, today will be my first time making this. I’m making this dish for an event, and I need to make enough to feed a hundred people or more. Can I make it in a disposable pan, and what suggestions do you have for me since it would require more ingredients. November 22, 2013 at 6:13am Reply

    • Jaclyn: Yes you should be fine to do it in disposable pans, you’d probably be fine to do double batches if you can find a pans large enough (basically twice as big as a 13×9). Then as far as the recipe goes I’d keep all the ratios the same, just plan accordingly for the number of servings you need (and even though you will be serving 100 people or more I might count on a little less because not everyone likes sweet potatoes (crazy people :)).

  • Beth: Hello! I made this last year and it was phenomenal! I’m remaking it this year, but I’ll be premaking it. I was wondering if it’s ok to mix the butter with the topping ahead of time, then put the topping in baggies for the next day, or if I should wait and mix the butter with the corn flake mixture when I’m re-heating the casserole? Thanks! November 23, 2013 at 5:25pm Reply

    • Jaclyn: I would wait to add the butter to the topping until the next day so that it’s not stale-ish. I’m so glad you made it last year and enjoyed it :)! November 24, 2013 at 2:04pm Reply

  • Mary: Hi! Just out of curiosity, why do you dice the butter into one inch pieces if you are browning it? November 27, 2013 at 6:48pm Reply

    • Jaclyn: For even melting. If you don’t dice it then some of the butter starts to heat quicker than that that’s still working on melting. I’ve just found it works best to dice it first. Good question :). November 27, 2013 at 8:05pm Reply

      • Mary Cassidy: Makes sense. Thanks for getting back to me so quickly! Can’t wait to make this tomorrow :) Happy Thanksgiving! November 27, 2013 at 8:09pm Reply

        • Jaclyn: Happy Thanksgiving to you Mary! November 28, 2013 at 7:09am Reply

  • Leonor Hernandez: I served this today at the PotLuck we had this afternoon for our newly opened Extra Store. I knew I would need to bring something extra special since this would be our first Thanksgiving PotLuck at our new location. Wow this dish really exceeded my expectations!

  • Melissa: Oh. My. Gosh. This was AWESOME. I wasn’t even going to make a sweet potato dish this year, because neither my sister nor my boyfriend really care for yams (weirdos), but upon my mom’s insistence, I found your recipe and set to work. Let me just say that EVERYONE, my sister and boyfriend included, absolutely LOVED this! My boyfriend actually said this was one of the best things he’d ever eaten! Thank you sooo much. This will definitely become an annual Thanksgiving dish. :) November 28, 2013 at 7:28pm Reply

  • Zipora: Looks amazingly delicious. Could you please let me know how to reduce the ingredients to serve 8.
    Also could I use chopped hazelnuts. My grandson is allergic to tree nuts. August 29, 2014 at 11:30pm Reply

    • Jaclyn: Yes you’d be fine to use the hazelnuts instead, and I would just cut everything back to 2/3 the original amount and probably bake in an 11 by 7 inch dish. I hope you love it! September 15, 2014 at 10:07pm Reply

  • Nhi Tran: Is it possible to make this in a square pan or is the recipe quantity too large? If i half it will it still be a decent quantity for a 8×8 pan or 9×9 pan? November 18, 2015 at 9:01pm Reply

  • 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

  • Kristine: Thank you for sharing such a beautiful sweet potato casserole!!

    I just made this but completely forgot the milk. Do you think it’ll make much of a difference? November 23, 2016 at 10:22pm Reply

    • Jaclyn: Since it’s only 1/3 cup you should be fine it will just have slightly thicker texture. I hope you love it! Happy Thanksgiving! November 24, 2016 at 8:42am Reply

      • Kristine: Thank you so much for your response!! The casserole came out amazing my whole family loved it!! Hope your thanksgiving was fantastic!! November 25, 2016 at 8:30am Reply
