Why we love this roasted sweet potatoes recipe
- 5 minutes of hands-on prep and you get to relax while they hang out in your oven and cook themselves.
- Miso tahini butter (just those three ingredients!) is so delicious that you'll be tempted to try a little spoonful before your sweet potatoes come out of the oven.
- That butter we swoon over adds the ideal savory element to balance the natural sweetness of the potatoes.
- It's a versatile recipe. Turn these into a vegetarian lunch or light dinner with a green side salad. Or serve them beside a larger dinner. They also make a great side at your Thanksgiving or Christmas dinners. (Although I would cut them in half for either of those as there's always SO MUCH food.)
- They reheat beautifully so they're great for meal prep.
- They are a healthy, sugar-free recipe that can easily be made vegan and gluten-free.
How to roast sweet potatoes
Oven roasted sweet potatoes are literally the easiest things in world to make.
- Rub a little oil on the whole sweet potatoes.
- Put them into a baking dish.
- Put them into your oven.
That's it! When you take them out of the oven, cut them open and put a spoonful of the miso butter on top. SO easy!
How long to bake sweet potatoes
Sweet potatoes vary widely in size, and therefore their cooking time varies, too. The sweet potatoes in this recipe are small (about 6-ounces) and take 35-40 minutes to bake at 400 degrees Fahrenheit.
Medium to large sweet potatoes can take anywhere from 45-60 minutes to roast.
To test if they're done, press the top with a spoon. If they feel soft, insert a knife into one of them. If it's soft throughout, it's ready!
