Slow Roasted Sweet Potato Recipe


  • 4 sweet potatoes
  • 2 tsp of kosher salt
  • 4 tsp of olive oil
  • 1 tsp of black pepper


  • Scrub the potatoes clean.
  • Preheat the oven to 275 degrees Fahrenheit.
  • Line a baking sheet with foil and place the potatoes on it.
  • Rub each potato with a little olive oil, salt, and pepper, coating all sides of the potatoes. Use as much or as little as you want of these seasonings to make the sweet potato just the way you like it.
  • Bake for about 2 ½ hours. That should give you potatoes that are caramelized on the bottom and soft on the inside.
  • Warm up the broiler and run your potatoes below it. Depending on your broiler, this can take anywhere from 2-10 minutes. You want the potatoes to become slightly charred on the top.
  • Allow the potatoes to cool slightly, on a wire rack, if possible. Crush the top of the potatoes slightly with your hand to reveal the inner flesh. Season the potatoes with some salt and top with butter if you like.

Why Roast the Potatoes?

Roasting is different from baking in two key ways. First of all, it usually involves a high heat, and secondly, it usually refers to foods that are not put into the oven in batter or liquid form. So, cakes, muffins and breads are baked, not roasted. You can bake a potato, but you cannot roast a cake, technically speaking. Roasting a sweet potato implies that it is cooked at a high temperature.

Roasting also usually implies some darkening, and to give the sweet potato a darkened look, you can either flip it over during the roasting process or run it under a broiler for a few minutes. Either way, you get a blackened skin on the top that gives it a little variety in texture and appearance. You will also see the skin turn a browner colour than before, actually changing from reddish brown to a darker shade as it roasts. That is a common characteristic for roasting any food as well.

This roasting method I provided in this recipe is going to take a while, and if you don’t have the patience for it, then you may want to cook yours in the microwave. It can come out okay there, but it won’t have a crispy crust. That’s the big difference between roasting and microwaving or any other kind of cooking method for your sweet potatoes.

If you want that crispy crust that is such a pleasure to cut into and see peel back and that tastes delightfully textured, then you need to slow roast it. The slower you roast the potato, the softer the interior gets and the crispier the outside gets, the two textures side by side make for an appealing combination.

You will definitely enjoy this dish more if you slow roast it as opposed to boiling or cooking in the microwave. I know it takes a while, but this is probably the best way to introduce the veggie to people who have never tried sweet potatoes. The soft, pillowy interior and the crispy outer skin, along with some gentle seasonings, make for an unforgettable first experience with sweet potatoes. If someone said that they don’t like sweet potatoes before, then once they try this, they might change their mind. That is how good it tastes, making believers out of people who formerly turned the sweet potato down.
