TIPS FOR MAKING CANDIED SWEET POTATOES
- How to mash sweet potatoes: Before you mash the sweet potatoes cut them into small pieces that are easier to break down. You can put the sweet potatoes in a blender to puree them more smoothly. You can also do it by hand with a potato masher or hand mixer. It’s up to you how smooth you want the mixture to be. If you’d prefer some more texture leave some chunks of sweet potato in the soufflé.
- You can also decide if you want to leave the peel on the potato or not. Sweet potato peels have a lot of nutrients, so if you’d like to keep them in your casserole you don’t have to peel the potatoes.
- Once the potatoes are mashed combine them with ½ cup white sugar, ⅓ cup unsalted butter, 2 large eggs, 1 teaspoon vanilla extract, and ½ cup whole milk. This will make the sweet and soft soufflé mixture.
- Spread the soufflé mixture in the baking dish, then sprinkle the crunchy streusel topping over the top.
- Bake for 30-35 minutes in a 350 degree oven. You’ll know the casserole is done when the topping is crisp and golden brown.

VARIATIONS ON SWEET POTATO SOUFFLÉ
- Spices: For some extra flavor try adding a teaspoon or so of cinnamon, nutmeg, ginger, or allspice. Whatever classic spices you use in your favorite holiday desserts could be great in this soufflé.
- Pecans: You can use pecans in the topping instead of walnuts. To make the pecan streusel just combine all-purpose flour, brown sugar, butter, and a cup of chopped pecans. You could also do ½ cup of pecans and ½ cup of walnuts.
- Marshmallow topping: If you want to make this soufflé more similar to a marshmallow sweet potato casserole, you can add mini marshmallows to the top instead of the streusel topping. Cook the soufflé without any toppings, then add the marshmallows and broil for 30 seconds until the marshmallows are golden brown on top.
