What Is The Difference Between Casserole And Souffle?

In general, a souffle is often fluffier and has a smoother texture. The fluffiness comes from eggs being added and the smoothness of the mixture from being blended. Casseroles can be chunkier and often have more focus on the toppings than the base, and don’t always contain eggs.

Crumble Topping

Mix together the following ingredients in a bowl:

  • 1/3 cup Butter, Unsalted, Melted
  • 1/3 cup All-purpose flour
  • 1/4 cup Shredded coconut, Sweetened
  • 1/2 cup Brown sugar
  • 1 tsp Cinnamon powder, Optional
  • 1 tsp Vanilla extract
  • 1 cup Pecans, Roughly chopped


Sweet potato souffle with marshmallows– Broil marshmallows on the top after the souffle is cooked for extra decadence.

Make it vegan– Use vegan butter, flax eggs, and plant-based milk for a vegan version.

Try other nuts– Add walnuts, almonds, cashews, pistachios, or even hazelnuts for more nutty flavor and crunchy texture.

Add other flavorings– Almond, amaretto, bourbon, or maple extracts would compliment this dish perfectly.

Add other herbs– Such as nutmeg, cloves, rosemary, or cardamom.

Add a zest– Like orange zest for a sweet, bright flavor addition.

Add seasonings– Such as pumpkin pie or apple pie seasoning for more warmth of flavor.

Tips And Techniques

How to thicken souffle? Add more sweet potatoes because the starch will absorb liquid. Another option is to continue cooking uncovered until excess liquid evaporates.

How to make souffle thinner? Simply add more milk to thin it out a little bit.

How to make topping crispy and crunchy? Take out the ceramic insert, and broil the souffle in oven to create a crispy top. Make sure to keep an eye on it, because it will crisp quickly, and if left unwatched, can burn.

Canned sweet potatoes vs. Fresh sweet potatoes– Canned potatoes is much faster since you don’t have to wash, peel, and cut the potatoes. Also, the timing for fresh potatoes would be different so they are not interchangeable for this recipe.

Adjust the sweetness– Add more or less sugar, according to your preference.

What kind of milk to use? I prefer whole milk, but 2% milk can be used, if needed. I would not recommend fat free milk because it doesn’t make this dish as creamy as I would like. If you use a non-dairy milk, make sure it is full-fat as well.

Adjust seasoning– Add more or less of cinnamon based on your personal preference.

What size crockpot to use? I recommend a 6 quart crockpot or larger to make sure all the ingredients cook through evenly and completely.


Refrigerate– In a sealed container for up to 3 days.

Freeze– I do not recommend freezing this because the pecans will become soggy when they thaw and the topping won’t be crunchy.

Reheat– In the microwave.
