Holiday dinners in my childhood often included a Corningware casserole dish of mashed sweet potatoes, mixed with brown sugar, butter and cinnamon and topped with marshmallows. Not just any marshmallow, however. More often than not they were the coloured variety: pale pink, green, and orange.
As kids, the only appeal of that dish to us was the gooey melted marshmallow topping! We'd make sure we all got our fair share, usually leaving the sweet potato mash on our plates.
Now as an adult, I shudder when I think of that dish. Why would you want to ruin naturally sweet, nutritious root vegetables with sugar and food colouring?
These Duchess Sweet Potatoes have a mellow earthy flavour. They're a comforting side dish, perfect for a holiday dinner. I know you'll love them, not only because they're delicious, but because they're easy to serve as individual portions, and you can prep them ahead of time.
So let's make this sweet potato side dish!
sweet potatoes: sometimes known as yams, depending on where you live, or where you shop!
cream: or milk, or non-dairy milk, to make these rich and creamy
eggs: to bind them all together!
herbs: like parsley, chives or fresh rosemary for garnish
Here's a quick overview of what you'll do to make these Duchess Sweet Potatoes. Complete instructions are in the recipe card below.
- Peel, chop and boil sweet potatoes until tender. Use an electric mixer to combine them with softened butter, milk or cream and eggs.
- Then the fun part begins! Fill a piping bag with the mixture and using a large star tip, pipe swirling mounds on to greased or parchment paper-lined baking sheets.
- At this point you can refrigerate them until serving time, when they'll only take 15 minutes to bake.
- Drizzle with a little melted butter and garnish with herbs and sea salt when they come out of the oven. Easy!
Sweet potatoes are a good source of beta-carotene, Vitamins C and B6, potassium, fiber and much more. They are on our weekday menus frequently because they're so versatile: roasted, mashed, hasselback, baked, or stuffed!
Before baking, top each swirled mound with a small amount of finely grated Parmesan or Romano cheese.
Try half and half! Use equal amounts of Yukon Gold potatoes and sweet potatoes instead.
Use whatever herbs you have on hand, like fresh oregano, thyme, parsley or chives. Don't forget to add a sprinkle of sea salt or freshly ground pepper.
Storage and reheating instructions
Store leftovers in a covered container in the fridge. To reheat, place on a baking sheet and place in a 350°F. oven for 10 - 15 minutes or until warm.
