If you're looking for the easiest side dish ever, this is it. Just four ingredients, golden and crispy on the outside, tender on the inside, with that hint of cinnamon spice. These baked sweet potatoes in air fryer are perfect for weeknight dinners, meal prep, or your holiday table.
These roasted sweet potatoes are especially popular in the fall and winter when cozy, warming dishes are a must. They're a staple side dish at Thanksgiving and Christmas but are just as perfect for everyday dinners, meal prep bowls, or even a weekend brunch spread.
Real talk? This isn't just a holiday side. I make these roasted sweet potatoes all week long. They're my meal prep hero, and my family adores them.
