Notes
How to cook sweet potatoes:
Instant Pot: Place trivet in the instant pot, add 1 cup of water. Stack the sweet potatoes on top of the trivet and cook on high pressure for 15 minutes. Allow pressure to naturally release. After cooking, the skin will easily peel off the potatoes.
Oven: Preheat the oven to 450F. Prick the skin 1-2 times with a fork and bake on a baking sheet for at least an hour. Allow to cool and peel the skin from the potatoes.
Stove: Peel the potatoes and chop the potatoes into equal size cubes (about 1 inch). Cover the potatoes with water and bring to a boil. Cook for 15-20 minutes until potatoes are fork tender (you can easily insert a fork and they pretty much fall apart). Drain off all water from cooking before mashing.
Microwave: Prick sweet potatoes 2-3 times with a fork. Place in microwave and microwave 10-15 minutes, depending on strength of your microwave. Allow to cool before peeling away the skin.

Make ahead instructions:
This is a great dish to make the night before if you are preparing for a holiday meal. You will want to make the sweet potato layer and the pecan topping but do not combine them until right before serving if possible (the pecans can get soggy). Store the sweet potato mixture in the fridge and the pecan topping in an air tight container on the counter or in the fridge.
If you have time, bake the sweet potato layer at 350F for 20 minutes. Allow it to cool, cover it and store in the fridge. The day you are serving this, add the pecan topping and bake 375F for 25 minutes.
If you don’t have time to bake this the night before, add the sweet potato mixture to the casserole dish, cover and store in the fridge. The day you are serving this, add the pecan topping and bake 375F for 40 minutes, covering the dish with foil for the first 20 minutes of baking.
Nut Free Sweet Potato Casserole:If you want a nut free sweet potato casserole you can use marshmallows in place of the pecan topping or use roasted sunflower seeds in place of the pecans and use your favorite gluten free flour in place of the almond flour. You can also make your own sunflower seed flour by grinding roasted sunflower seeds in a food processor about 1 minute until they resemble flour.
