Here is a twist on your traditional sweet potato casserole.
When I was young, my grandmother used to make her sweet potato casserole with Cajeta for Thanksgiving. My initial plan was to make it, but I could not find any Cajeta nearby. So I decided to make the same recipe with dulce de leche. Cajeta and dulce de leche are basically the same. A difference is that Cajeta is made with goat milk and dulce de leche is made with cow milk.
This recipe came out delicious and I recommend trying this dish for your Thanksgiving dinner next week. The sweet potatoes were gooey and sweet! I forgot how much sweetness marshmallows add when you place them on top of the sweet potatoes.
I did boil the sweet potatoes the night before for 40 minutes and they were still soft enough to be mashed the next day when I decided to make the casserole. If you are needing to prep for Thanksgiving and want to make this dish, I think you are safe to boil the sweet potatoes the night before. It might save you some cooking time Thanksgiving Day.
I hope you all enjoy this recipe! Let me know how it turns out.
