🍠 Ingredient notes
- Sweet potatoes - I prefer to steam sweet potatoes before mashing them for the sweet potato base. It's quicker than baking them and they don't get too mushy or water logged from boiling. Instructions are listed below for two different methods you can use to steam the potatoes.
- Maple Syrup - I recommend using pure maple syrup as opposed to pancake syrup for the sweet potato mixture. It will give a more pure maple flavor to the sweet potato filling without it being overly sweet.
📋 Substitutions and variations
- Dairy Free/Vegan - Substitute the half and half for unsweetened non dairy milk. Replace the butter for a dairy free or plant based butter substitute.
- No Nuts - The nuts can be omitted from the topping to make a simple brown sugar topping for the sweet potatoes.
- Marshmallows - Mix ½ cup of mini marshmallows in with the brown sugar, butter and pecans.
🔪 Step by step instructions
First, peel, chop and steam the sweet potatoes. Instructions for using either the instant pot or steamer basket method are listed below.
Combine the sweet potatoes in a large bowl with the half and half as well as the maple syrup. Mash or whip the potatoes using either a potato masher or a hand mixer. Then stir in the cinnamon, cloves, nutmeg, allspice and salt.
In a small bowl, mix together the topping ingredients until they are thoroughly combined.
Spread the seasoned, mashed potatoes in a greased baking or casserole dish and then sprinkle the pecan mixture evenly over the top of the sweet potatoes.
Bake the sweet potatoes in oven for about 35-40 minutes until the potatoes are heated through and the top of the casserole is slightly browned and bubbling.
If you ever don't recognize a tool or skill that I mention, be sure to look it up in the Glossary of Cooking Terms and Definitions for more information.
⭐ Expert tips
- Cut the potatoes into similar sized pieces that are approximately one inch, to help them steam quickly and evenly.
- The sweet potatoes can be mashed to your desired consistency. For more texture, mash the sweet potatoes roughly. For a smoother consistency, use a potato ricer to process them.
- If you use an electric mixer or food processor to whip the potatoes, make sure to not over mix them, or they will become gluey in texture.
- Make sure the butter is softened so that it thoroughly combines with the brown sugar and pecans.
🍠 Steaming sweet potatoes
To steam the sweet potatoes perfectly, either an instant pot or steamer basket in a pot on the stove top may be used.
instant pot method
- Peel and chop the sweet potatoes into one inch cubes.
- Place them in the inner pot with 1 cup of water.
- Place the lid on and lock it into position, making sure the release valve is set to the "sealing" position.
- Using the manual setting, set to high pressure for 10 minutes. Once it comes to pressure, it will seal and begin the cooking time.
- Once the cook time is complete, carefully flip the release valve to the "venting" position to quickly release the pressure.
stove top method
- Peel and chop sweet potatoes into one inch cubes.
- Add about one inch of water to a large pot and place a steamer basket inside.
- Place the sweet potatoes in the steamer basket, cover it with a lid and place on the stovetop on medium high heat.
- Simmer for 15-20 minutes until the sweet potatoes are fork tender.
