Roasted Japanese Sweet Potato Rounds

Have you tried Japanese sweet potatoes before? If not, please do.

They have such a unique flavor and texture. If you're not a fan of regular sweet potatoes, you might find these Japanese sweet potatoes to be quite delicious. Or even if you do love regular sweet potatoes, Japanese sweet potatoes can become a refreshing change of pace.

Plus, baking Japanese Sweet Potatoes is simple and easy. I make them all the time!

What are Japanese Sweet Potatoes?

Japanese sweet potatoes are not like regular sweet potatoes. Yes, both are potatoes and both are sweet, but that's about where their similarities stop.

'Regular' sweet potatoes are orange inside with brownish skin. They are very fibrous and slightly sweet. Their flavor is mellow and neutral, good for combining with other flavors.

Japanese sweet potatoes, on the other hand, are light yellow inside and their skin is purple. These potatoes have an intense sweet flavor -- I've even seen a recipe for icing using Japanese sweet potatoes. They are not fibrous at all, instead their insides are gooey and creamy. In other words, they are amazing!

As a side note, I have nothing against regular sweet potatoes. Because of their bright orange insides, regular sweet potatoes likely have more antioxidants than Japanese. Regular sweet potatoes have their place, I often make this recipe with them.

I much prefer the Japanese sweet potatoes in this recipe. Because of their super sweet flavor, you don't need a sauce or dressing. They are so delicious eaten plain. But, you do you -- if you want to dip them in something, go for it! I suggest peanut butter.

Ingredient Notes

  • Japanese Sweet Potatoes: Yep, just one ingredient. There's no need for oil - these potatoes get a nice lovely brown without any oil or butter! Bonus points for less fat and more fiber.

How to make Roasted Japanese Sweet Potato Rounds

Baking Japanese sweet potatoes is so easy! For these Roasted Japanese Sweet Potato Rounds , the only thing you need to pay attention to is how thick you cut your slices. For the perfect amount of browning (aka flavor!!) you need to cut slices less than a centimeter thick.

I like to vary my slices slightly. When not all the slices are exactly the same, you'll end up with some that are really brown and some that are only browned slightly. I don't measure my slices, but they vary between 1/4 cm and 3/4 cm.

Step 1. Preheat the oven to 425°F.

Step 2. Thinly slice the sweet potatoes (between 1/4 cm and 3/4 cm).

Step 3. Arrange on a baking sheet and bake for 40 minutes. Flip halfway through. Enjoy!

Alternate ways to Bake Japanese Sweet Potato

You can make more than just rounds with your Japanese sweet potato. These delicious potatoes are SO versatile!

Bake Like a Regular Sweet Potato

To bake Japanese sweet potatoes whole, just bake as you would with a regular sweet potato. Poke some holes in the potato with a fork and then bake at 400°F until the potato is fork tender.

Spread a little vegan butter inside or sprinkle with cinnamon and you've got yourself a tasty treat!

Use in a roasted vegetable recipe

Japanese sweet potatoes add a unique flavor to any dish. Use them any time you make a roasted vegetable or potato recipe. Some recipes they might taste good in are:

Bake in Brownies

Yes, you read that right. Sweet potato brownies!

After you bake your Japanese sweet potato you can add it to brownies or blondies for a natural sweetener. I love using sweet potato in brownies because it creates a super fudgy texture.

Make Frosting

Since Japanese sweet potatoes are a light white color, they are perfect for plant-based frosting. They don't add any funky color to the icing. They do, however, create a super thick buttercream-like frosting that is naturally sweet.

Check out these chocolate cupcakes or these maple pecan cupcakes for my frosting recipes using Japanese or white sweet potatoes.

I was in the middle of making your Tempeh Swiss Chard recipe and noticed you never mentioned how much Swiss Chard to add. I just added the sautéed tempeh towards the end and mixed it all together. I also reduced the amount of red pepper flakes.
Hi Jenny - so sorry about that! It should be one bunch. I've updated the recipe to include the correct information. Thanks!

Elissa
This looks fantastic! Do you think we could substitute butternut squash for the acorn squash?
Hi Elissa - you can definitely use butternut squash. In terms of texture, the pie will be exactly the same with either squash. I'd recommend using the volume measurement instead of the weight measurement, since the density of butternut squash isn't exactly the same as acorn squash. Also, the flavor of the butternut squash might come through in the end pie a bit more prominently than acorn squash does, but I don't think it will be too noticeable. Let me know how it goes if you try with the butternut squash. I'd love to hear!

THIS LOOKS DELICIOUS! DID YOU USE FIRE-ROASTED TOMATOES?
Hi Katherine - yes, I did use fire-roasted tomatoes when I photographed this recipe. I don't call for fire roasted in the recipe because it's intended to be a basic, use-in-anything type recipe. But it does taste delicious with the fire roasted tomatoes! -- Elizabeth

As someone who has pretty much never successfully scrambled tofu - this was the best scrambled breakfast dish I've ever had - better than eggs and the seasoning is truly delicious!!
Oh, amazing! So glad to hear it went well :) This is definitely one of my favorites - thanks for sharing your kind words! -- Elizabeth

I enjoy reading through your recipes and will be trying a few later in the week. I especially like the prayers at the end of each recipe. It reminds me to be grateful God provides me with so many beautiful and nourishing fruits and veggies.

I really enjoyed this recipe. Fits PERFECTLY in my allergy to foods world. I used Ripple milk and no sugar added SunButter. Was truly surprised at how quickly the recipe came together! Thank you!
Hi Vickie - I'm so glad you enjoyed this recipe and that it works with your allergies. Thanks so much for leaving a comment with your kind words!

It's close to my bedtime, but I've been thinking about making this recipe all day, so I made it just now. After all, it only takes 15 minutes! I used what I had, so I made a few minor substitutions...white beans for cannellini, purple basil from my garden, red onion for more color, and date syrup for maple. I took a bite before putting it in the fridge for tomorrow, and oh my! It's delightfully flavorful, light, and fresh-tasting. Thanks for sharing your recipe!
Hi Linda - I'm so glad you liked the recipe - and your substitutions sound great (wish I was growing purple basil in my garden!) Thanks so much for sharing!

Hi, is this ice cream soft to scoop out? I always find my ice creams are hard.
Hi Carol - yes, this ice cream is soft if you let it thaw a few minutes after you take it out from the freezer. It can become pretty solid if it's in a deep freezer, but still thaws quickly on the counter. Hope this helps!

Hi Elizabeth! I found you by searching for plant based Catholics! There are very few of us! Thank you for your site and sharing recipes!! I look forward to trying these muffins! Can sugar be reduced safely in most of your recipes? -JMJ-
Hi Katherine, Thanks so much for reaching out! Glad to meet another plant-based Catholic - agree, there are so few of us. As for sugar, I never use white granulated sugar in any of my recipes. Most use maple syrup or date sugar/date syrup. I'm not sure if this is what you mean, or if you're asking about reducing the amount of date sugar that the recipe calls for. If that's the case, it really depends on the recipe. A lot of the baking recipes have specific ratios of flour to sugar and wet to dry, so it may not go well if you change the amount of sugar. I hope this helps, but if I didn't answer your question, please let me know. Also happy to advise on a particular recipe if you're looking to change it. Let me know how I can help :) Elizabeth

Love this vegan lentil/mushroom stew! For some odd reason, I had never thought to put mushrooms into my lentil stew. Thank you for a wonderful addition to my recipe box!

Hello, I found you on FB and really enjoy your Catholic Plant Based GF information & recipes. About the Chickpea beet burgers: if the beans are dried and not cooked, do you think it is enough cooking for the beans? If beans are not cooked completely I have read they are toxic with phytic acid & also cause digestive problems. I am just wondering and will leave it to you to decide/research. To be safe I am toasting canned garbanzos and trying that way out. God Bless
Hi Geraldine, Thanks so much for reaching out. In the beet burgers, the beans do get cooked when the burgers are cooked. You soak them first and then incorporate the beans into the burger patty, then cook the patty. I find that this is the best way to achieve the proper burger texture - if you use pre-cooked beans or canned beans the burgers are mushy and don't get crisp. Your solution of toasting the beans sounds like a great idea to completely ensure the beans are cooked fully - I hope that it worked for you and your burgers turned out well! -- Elizabeth

Can you leave nutritional info for your recipes? Serving size/calories would be so helpful! Trying mushroom lentil stew tonight! and looking forward to crispy chickpea stuffed sweet potatoes very soon. Thanks for creating healthy, attractive recipes!
Hi Katie - so excited to hear that you are trying some of my recipes! I'd love to hear how they go. I haven't posted nutritional information for my recipes because I know it can be difficult for some people with disordered eating to see nutrition facts. I've gotten a lot of requests to add them recently, so I'm working on a solution that can provide information for those who want it but not be triggering for others. In the meantime, if you're curious about the nutrient info about a particular recipe, I recommend using Cronometer. It's a website/app to track and understand nutrient info and I think it does a great job of emphasizing all the nutrients (not just macros). I hope this helps! Please let me know if I can help in any other way.

Hi Vickey - thanks so much for catching that! I am updating the post now. So happy to hear you enjoy my recipes. And exciting that you are thinking about going vegan!! If there's anything that I can do to help, please let me know.

Sr Maureen Egan
I'd love to try this soup. What are the nutritional values, like how much fat does it contain, carbs, etc.
Hi Sr Maureen - I usually don't post macronutrient information because I know each person has their own goals and I don't want to encourage or discourage anyone's specific goals. But I often use Cronometer as a tool to understand the nutritional profile of my recipes. I plugged the ingredient information for this recipe into Cronometer and got the following nutrient information per serving: 521 calories, 44g fat, 23g carbs, 16g protein. I hope this helps. Please let me know if you have any other questions and if you try the recipe!

Thank you I have been doing the fruit and oatmeal, etc for years and I love it. I will try the pears. I refrigerate my left over oatmeal and with a touch of milk or fruit juice liquid it’s fine the next day. Just a warning about tofu; it interferes with some medicines especially Thyroid medicine. Thank you for the short prayers, there are lovely.
Hi Martha - thank you so much for your kind words. I'm glad you like the prayers! As someone who doesn't take any medications I have no issues with eating tofu and encouraging others to eat it too (it's a great source of protein!). That said, you should always consult with your doctor about possible interactions with medications. I have plenty of recipes without tofu, so hopefully you can find things that work for you!

I made this for Ash Wednesday and it was delicious. It was also simple and not much work time once the mushrooms and onions were cut.

When you say shape into a rectangular loaf, what dimensions? 1/2 thick by 8 inches long or?
My loaf was about 7" long and 4" wide with about 1" of height. Then I sliced it 1/2" thick along the long end to get 12ish biscotti. I will clarify this in the post! Let me know if this makes sense and if you have any other questions.

Hi Could you please confirm two things:1. The amount of salt. Seems like too much. 2. The directions say there is lemon juice in the dressing but it’s not listed under ingredients. ThanksL.
Hi there! Confirming that the two teaspoons of salt in the dressing is correct. I didn't salt the cauliflower when roasting it or the salad after it was done, so this amount of salt was perfect. If you're concerned about it you can decrease the amount of salt in the dressing and then add more at the end if you need it. As for the lemon juice, SO sorry about that! It was a typo in my directions and I've removed it now. Hope this helps :)

This looks lovely! Do you have a recipe for the red pepper hummus also? Thank you!
Hi Martha! I don't have a recipe for red pepper hummus on my site. I suggest taking a traditional hummus recipe and blending in roasted red pepper.

Grace
Hi, these look amazing. I was wondering, could I used powdered peanut butter in place of creamy for the recipe? thanks
Hi Grace! There is already some powdered peanut butter in this recipe, so adding more might make the texture more gluey. Also, the real peanut butter adds some fat, which helps create flavor. That said, if you want to use powdered peanut butter, I would suggest mixing it with a high-fat liquid like coconut cream and then measuring out 2/3 cup. Hope this helps! Let me know how it goes :) -- Elizabeth

You mention using vegetable broth in your introduction but it isn’t included in the recipe
Hi Becky - thanks for pointing this out. I have removed mention of vegetable broth from this post. You do not need any vegetable broth. The mushrooms will release natural liquid which will prevent any sticking. -- Elizabeth

thank you for the oil free recipe. I'm getting introduced to wild Bolete mushrooms here in Colorado, and everyone sautes Bolete's in butter or olive oil. I'm on a veggie, oil free regimen for heart health reasons. and your recipe suggestion may fill the bill. I can't wait to give it a try.
