Cinnamon Sweet Potatoes

I love how versatile sweet potatoes are! If you’ve made my Sweet Potato Toasts or Sweet Potato Tuna Melts, you know they can be a staple recipe and pairs well with just about anything! The combination of sweet potato and cinnamon always makes me think of fall! It truly is such a warming and flavorful combination.

Sweet potato cubes tossed with oil, salt, and cinnamon, then roasted to caramelized perfection have become a staple in my home! Perfect vegan side dish for meal prep and to have on hand for any meal throughout the week!

Ingredients Needed:

This vegan sweet potato recipe couldn’t be easier! Scroll for the full recipe to see how it comes together!

  • Sweet Potatoes: Any variety!
  • Avocado Oil or Olive Oil: Any oil, or even butter, works great here. If using butter, melt it!
  • Ground Cinnamon: The key to the best roasted sweet potatoes.
  • Sea Salt: Use good quality, fine sea salt, and even add some flakey salt to garnish afterwards, if you’d like!

Tools I Used:

The Best Sweet Potato Variety

I love using classic garnet or jewel sweet potatoes here! I also love using Japanese sweet potatoes, which have a white flesh!

How To Cut Your Sweet Potatoes

Feel free to get creative with how you cut the sweet potatoes! Dice them into cubes (1-inch chunks), or cut them into wedges, thin circles, or sweet potato fries.

How to Roast Sweet Potatoes

  1. Cut them evenly: Try to cut your sweet potatoes as evenly as you can, into 1-inch cubes!
  2. Be generous with your oil: Use good quality oil (butter works here, too!), and use enough to coat the sweet potatoes evenly.
  3. Lots of flavors go well with sweet potatoes: All we are using is good salt and ground cinnamon (the best combination!), but you can add other seasoning as desired: garlic granules, black pepper, thyme, etc.
  4. Roast them right! You don’t want to make your oven too hot, where they will burn, but 400 degrees is just right to cook them a bit slower, but results in that perfect caramelization that we want!
  5. Avoid soggy sweet potatoes! We got this! Simply spread them out in an even layer with enough room so that they aren’t crowded!

Health Benefits of Cinnamon

Cinnamon is one of the healthiest spices and one I use almost daily. It’s really great for digestion, and is loaded with antioxidants and filled with anti-inflammatory properties.

What to Serve These With

I make a batch of cinnamon sweet potatoes weekly for meal prep, to have with lunches or dinners, and for our daughter Skylar! These roasted cinnamon sweet potatoes are perfect with eggs in the morning (think home fries) or serve it with your dinner, like Seared Steak, Chimichurri Chicken, or Chili Maple Glazed Salmon, and other Oven Roasted Vegetables.

  1. These are so yummy, my toddler loves them! Do you think they’ll hold up if I make a double batch and then portion them to freeze in baby food jars?

  2. These are so delicious! I made these for Thanksgiving and everyone loved them. I prepared them at home and brought them to the party where I quickly reheated them in an oven and they came out nice and lightly crispy. I’m making them for Christmas per everyone’s request! They were a big success even with people who said they didn’t like sweet potatoes lol.
    Thank you for this easy, delicious and healthy recipe. My family loves these sweet potatoes.

  3. Would it ruin them if I followed your recipe and then when they are done put them in a crockpot to keep them warm/hot to take to a family gathering.?
