Ultimate Sweet Potato Casserole With Pecan Crumble Topping

Ultimate Sweet Potato Casserole Recipe

No Thanksgiving meal would be complete without an Ultimate Sweet Potato Casserole dish.  I’ve tried many recipes over the year and have refined my sweet potato casserole recipe to maximize the sweet potato flavor with a delicious toasted and crunchy pecan crumble on top.  This is so good, you might think it’s a dessert during the meal.

I’ve found many sweet potato casseroles are loaded with sugar, but I’ve tested using less sugar and determined that you really don’t need to have a ton of added sugar to have an amazing dish.  I only use 1/3 cup of white sugar in the casserole and 1/3 brown sugar on the top for the pecan crumble.  This way, you really taste the sweet potatoes rather than just a sweet sugary concoction.

I always make my sweet potato casserole the day before Thanksgiving and refrigerate without the pecan crumble.  On Thanksgiving, I let the casserole come to room temperature while the oven is heating then make the pecan crumble and bake about 1 hour before guests arrive.

This way the crumble doesn’t get soggy and the dish stays warm in the oven while I prepare the other dishes.  I like to roughly chop the pecans with a knife on a cutting board so that there are larger pieces of pecans in the crumble.  Take advantage of the hot deals on brown sugar, eggs and pecans to make this sweet potato casserole for your Thanksgiving table.

  1. Thank you for sharing your recipe! Have you ever tried substituting a half can to one whole can of crushed pineapple instead of using white sugar? My late mother-in-law always mixed it into her sweet potato casserole and I fell in love with it! I don’t measure the pineapple, just add a little and taste until you like the taste of it. I’m excited to try the pecan crumble topping!

    1. I have not ever tried that. Sounds interesting and I will have to try it sometime. Doesn’t the pineapple flavor come through in the dish?
