Sweet Potato and Butternut Squash Gratin



My girlfriend said that this is the first recipe she has ever heard me say that I love. I’d say that this must be some pretty darned good Sweet Potato and Butternut Squash Gratin. Wouldn’t you?


Well, I do pick apart everything that I cook because I want it to turn out perfect before I post it to you guys, but I truly did love this dish. I totally ate it for lunch the next two days, which pretty much NEVER happens.


One of the best parts about this gratin is that you can actually taste the squash and sweet potatoes. Sometimes things are drowning in the cream and cheese so much that it feels like a cream overload. I also love the gruyere cheese. It’s flavor melds perfectly with everything, so it’s almost hard to tell if it is alone or in the sauce. I love that.

My favorite, favorite, favorite part is the sides and very top where the Gruyere gets a little more crisp. MMMMMMMM, I love the crispy cheese on the sides of the pan. LOVE IT!


This is a fantastic side dish, but I see nothing wrong with eating it with a lovely spring salad. Hooray for changing up the basic potatoes augratin for something a little more sophisticated, but still just as easy and delicious!

  1. um, “Amount Per Serving: Calories: 3972 Calories” ??!

  2. Hello, wanting to make this recipe x 2 for a weekend Thanksgiving dinner. Can the whole thing be made the night before an afternoon meal, or assembled with the sauce and refrigerated before baking? Thank you!

  3. Hello! I found this recipe and it sounds delicious! I want to make it for thanksgiving this year. How many servings does this make?? We have 8 adults and 4 kids (all under age 3 so they probably won’t eat a whole lot). Thanks!

    • It only served 4-5 adults for us, but maybe that’s because I could have doubled it and stacked everything higher in the dish. I would say double in a 9×13 or even triple in a 9×13 so it stacks up higher and one scoop will be more filling.

      • Thanks! One more quick question then Ill leave you alone, promise! How much is a tub of chicken stock (volume wise)? I have only bought cartons before, and I am going to attempt to get the same brand you did but if the store doesn’t have it I will have to get another brand. Just trying to figure out how much I will need in ounces/cups/etc.

      • oh, no! You can email me anytime! Ok, so those little tubs can be tricky to find. I’d call around before leaving the house, and if you can’t find them I’d honestly skip it. It’s like a jelly in consistency and it’s so small that a straight liquid would be too much.

      • awesome thank you for all the advice and answers!!

  4. Sounds like a great Thanksgiving dish!
