Key Ingredients

  • Thyme. I always use fresh thyme in this recipe. It bakes better than dry thyme and adds so much extra flavor.
  • Sweet Potatoes. I recommend orange-fleshed sweet potatoes as they have a softer texture and hold more moisture. But you can experiment with white-fleshed varieties and yams as well. 
  • Garlic. Whole garlic cloves infuse the entire dish with a nutty, savory sweetness and add a richness beyond what you’d get with garlic powder.

Step-by-Step Instructions

1. Prep the Ingredients. Place sweet potatoes, garlic, and thyme on a parchment paper-lined baking sheet. Drizzle with olive oil and sprinkle with spices.

Recipe Tips, Substitutions, and Variations

  • Don’t rush it. Let the roasted sweet potatoes cook as long as needed. It can take between 25 and 45 minutes for them to get tender and start to brown.
  • Make uniform sweet potato cubes. For uniform cooking, I’ve found it’s very important to cut your sweet potatoes into the same-sized cubes. I aim for 1-inch cubes, but you can go a little smaller to reduce the cooking time.
  • Substitute garlic powder. I highly recommend fresh garlic if you have it. But if not, toss sweet potatoes, olive oil, and ¾ teaspoon garlic powder in a bowl before spreading over the baking pan.
  • Substitute rosemary for thyme. If you’re out of thyme, I’ve found fresh rosemary also works very well in this recipe. 
  • Out of honey? You can substitute pure maple syrup. Honey is sweeter, so you’ll need to add 1 1/4 tablespoon syrup.
  • Add toasted pecans. One great variation I return to with this recipe is to garnish it with roasted pecans. The combination of crunchy pecans and the crispiness of the roasted sweet potatoes is just so good.

Make Ahead and Storage Recommendations

To save time, I often prep this dish early. I cut the sweet potatoes and mix them with garlic, thyme, olive oil, and spices in a large container. I pop this in the fridge until I am ready to bake.

That way, when you’re ready to eat, all you have to do is spread them over your baking sheet and roast for 25 to 45 minutes.

If you have leftovers with this dish, place them in an airtight container and store them in the fridge. They will stay good for three to five days.

Reheat by spreading them over a baking dish and cooking at 400 degrees Fahrenheit until warmed through.
