Brown Butter Mashed Sweet Potatoes Recipe FAQs
How do I know if my sweet potatoes are good for mashing?
Choose firm sweet potatoes without soft spots or wrinkles. The skin should be smooth, and the flesh inside bright and moist. If your sweet potatoes have dark spots all over or sprouting eyes, it’s best to avoid them for a creamy mash.
Can I store leftover Brown Butter Mashed Sweet Potatoes in the fridge?
Absolutely! Store leftovers in an airtight container for up to 3 to 4 days in the refrigerator. When you’re ready to enjoy them, reheat gently in the microwave or on the stove with a splash of cream or milk to bring back that silky texture.
Is it okay to freeze Brown Butter Mashed Sweet Potatoes?
Yes, but with a few tricks. Portion the mash into freezer-safe containers or heavy-duty freezer bags, removing as much air as possible. Freeze for up to 2 months. Thaw overnight in the fridge before reheating slowly on the stove with a little cream to prevent dryness. I recommend freezing only if you have no other option, as freezing can slightly change the creamy texture.
What if my mashed sweet potatoes turn out watery or grainy?
Don’t worry, it happens! Wateriness often comes from overcooking or not draining the potatoes well. After boiling, let them sit in the hot pot for a couple of minutes to steam off excess moisture. Use a potato masher or ricer to gently mash—vigorous mixing can release starches, making the mash grainy instead of smooth.
Can I make this recipe if I’m lactose intolerant or have allergies?
Very much so! Swap out the butter for a lactose-free or dairy-free variety like coconut or vegan butter. For creaminess, use almond milk, oat milk, or another plant-based milk. Just keep in mind these alternatives may slightly alter the flavor, but the comforting essence of brown butter mashed sweet potatoes will still shine through!
