Baked Sweet Potato using the easiest method ever! Super simple, tried and true way that shows just how easy it is to bake a sweet potato.
I adore baked sweet potatoes but it took me a while to figure out the best way to cook them. I prefer baking them because they’re soft and tender and have the best flavor. They’re great for side dishes or lunch as sweet potatoes are high in protein and fiber as well as vitamin A, vitamin C and vitamin B6. Sweet potatoes even contain iron and protein! They have no fat or cholesterol and a medium sized sweet potato only has about 120 calories. Now of course, you can add whatever toppings you like- it’s up to you how healthy you want to be! I love adding butter and some marshmallows. I think adding pecans is a great idea as well!
How to bake sweet potatoes
This is my easy way to bake sweet potatoes. First, start by preheating your oven to 400 degrees F. Scrub your sweet potatoes and cut off the ends. Place on a baking sheet lined with foil, parchment paper or teflon baking mats. I have always been a die-hard fan of parchment paper, but I recently tried teflon baking mats and LOVE them. They’re washable, everything is non-stick, yes, even this baked on sweet-potato mess, and they’re virtually indestructible!
–Bake for about 45 minutes to an hour. I baked my 2 medium sized potatoes for 1 hour. Adjust the time if your potatoes are larger or smaller. If you’re unsure when they’re done, the inside should read 210 degrees. My digital kitchen thermometer is one of my favorite tools!
–Cut a large “X” onto each potato and pull back the skin a bit. It will just peel away easily. Sprinkle with a little salt and dot with butter. Add about 1/4 to 1/3 cup of mini marshmallows to the top of each potato. Return to the oven to broil for 2-3 minutes, or until marshmallows are toasted a light golden brown.
–Serve sweet potatoes after they’ve been able to cool down for about 5-10 minutes.
