Boiling Method:

One of the alternate methods to making a sweet potato casserole is by boiling the sweet potatoes first.

Simply wash the taters and drop them into a large stock pot.

Cover them with water and bring them to a boil. Let them boil for about twenty (20) minutes.

Then, remove them from the heat and carefully drain the sweet potatoes. Set them aside to cool a little before peeling and dicing them into cubes.

Baking Method:

Another method is to wash the potatoes and wrap them in aluminum foil. Use your knife or a fork to poke holes (not all the way through) into the potatoes.

Place them into a preheated oven at 400 degrees F. to bake for sixty-five to seventy (65-70) minutes or until they’re fork tender.

After that, set them aside to cool until they can be peeled and diced. We have one more method to address before we move on.

Pressure Cooker Method:

Start by dicing your sweet potatoes before you cook them. Next, place the taters into an approved pressure cooker steaming basket.

Then, grab your Instant Pot liner and put it into the cooker. Add one (1) cup of water to the liner. Afterward, put the steamer basket in place.

The taters are being pre-cooked in a pressure cooker.

Close the machine and set the valve to, “sealed.” Using the manual/high pressure cook button, set the timer for seven (7) minutes.

Last, allow for a five (5) minute natural release. Transfer the sweet potatoes to a large, heat-safe mixing bowl.
