Ingredients:

You’ll need a simple, classic set of ingredients to make the casserole. Exact measurements are listed in the recipe card below. Here’s a brief overview.

Sweet Potato Base : Cooked, peeled and mashed sweet potatoes, lemon juice, maple syrup and pinch of salt.

Pecan Maple Oats Granola : Pecans, Old fashioned rolled oats ( I used certified gluten free version ) , maple syrup, coconut oil or butter and ground cinnamon. You can use all purpose flour but I like the texture that oats bring.

Marshmallows : Optional but let’ face it…we use them a lot. A layer of toasted marshmallows on top is everyone’s favorite. You can use vegan and gluten free marshmallows to make this casserole suitable for vegan, dairy free and eggless. Trader Joe’s Whole Foods and Amazon has them easily available.

Instructions :

Make the Sweet Potato Base: Mix together cooked, peeled and mashed sweet potatoes with lemon juice, maple syrup and pinch of salt. I am including instructions to easily cook sweet potatoes in Instant Pot. Make this step ahead of time and use it to put together this casserole last minute.

Prepare Pecan, Maple and Oats Granola : In a medium bowl, combine the ingredients listed for the pecan granola Pecans, Old fashioned rolled oats ( I used certified gluten free version ) , maple syrup, coconut oil or butter and ground cinnamon. Mix well so it forms a crumble / granola-like texture.

Bake : Bake at 375 degree Fahrenheit in a pre heated oven for 20-25 minutes. Remove from the oven. Scatter marshmallows on top. Put it back in the oven under the broiler setting for 3-5 minutes so that marshmallows get toasty. Remove promptly. Serve warm. Enjoy !

How Do I Store the Leftovers?

Your leftover sweet potato casserole can be refrigerated for up to 3 days. Just remember to cover the container well to keep out any refrigerator smells. Then, when you want to serve it, allow it to come to room temperature, and then just reheat it in the oven for a few minutes to crisp up the streusel once again.

Pro Tips

The recipe is easy, but you wouldn’t want to miss out on some good tips and tricks to to make it failproof.

  • If you want to make this dish ahead of time, you could do that too. Assemble the dish, cover it up and refrigerate it for up to 2 days before you decide to serve it, or you could make the streusel topping a few days in advance and then use it when needed.
  • It is always best to bake the casserole right before you serve.
  • Instead of just the ground cinnamon, using ready made pumpkin pie spice works beautifully and adds wonderful flavor.
  • To keep the streusel from burning or browning up too much, cover it with some aluminum foil for hlaf part of the baking .
  • While making the streusel, you could also replace the maple syrup with brown sugar to lend the casserole an extra depth of flavor.
  • Looking for a quick shortcut to make this recipe? You could use canned yams instead of going through the process of boiling and mashing the fresh sweet potatoes.

Serving Ideas & Suggestions

This sweet potato casserole tastes best when it is fresh out of the oven. Of course, you would want to allow it to cool down for a few minutes before you serve, because it is going to be piping hot!

Top it with vanilla ice cream, whipped cream whipped Greek yogurt for extra decadent treat. I like to whip up coconut cream with dash of nutmeg and brown sugar and add a dollop on the top. It is a sensory delight !

Cooking Sweet Potatoes in Instant Pot

Add 1 cup of water to the insert of a 6 quart Instant Pot or 1.5 cups to an 8 quart Instant Pot. Put a trivet or steamer basket to the Instant Pot and arrange sweet potatoes on it. Place the lid on the Instant Pot, and set the valve to 'sealing'.

Cook on High Pressure for 15 minutes followed by natural pressure release. Remove the lid when the silver pin drops and then remove the sweet potatoes and use as needed.
