  2. Insert an oven-safe rack inside of a rimmed toaster oven baking sheet.

Toaster Oven Baked Sweet Potatoes 101:

Alright, you ready to do this? Great, let’s grab a few sweet potatoes from the store.
 
CAN YOU SPOT THE YAM?
Sweet potato varieties at a grocery store.
Hold on, what’s the difference between yams and sweet potatoes?

When we first started buying sweet potatoes, this yam thing was super confusing. I want to make it easy for you…there are ZERO yams in the picture above.

Despite what the signs say, ALL of those are just different varieties of sweet potatoes.

There are a lot of interesting articles (like this one from Bon Appetit) about where real yams come from, how they’re different from sweet potatoes, and the history of why we call some sweet potatoes yams.

But here’s the thing, you don’t need to know ALL about yams to bake a sweet potato in your toaster oven.

Now, that’s way more related to your current dinner goals.
 
SWEET POTATO VARIETIES
GARNET: Have a darker red skin color with deep orange flesh. When baked the Garnet sweet potatoes have flesh with a slightly heartier texture that is still creamy and sweet but more earthy like an acorn or butternut squash.

JEWEL: Our favorite of all the varieties, Jewel sweet potatoes have orange skin and flesh. They are sweeter and creamier than Garnet’s when baked with a flavor that’s more reminiscent of pumpkin.

PURPLE STOKES: You’ll probably encounter a lot of spuds labeled as “purple sweet potatoes” in this instance we’re talking about ones where the skin and flesh are purple. We’ve found the Purple Stokes variety to be less sweet and much drier than the Garnet or Jewel. With those qualities, purple sweet potatoes are a better choice for roasting.

HANNAH: These lighter colored sweet potatoes have a white skin and flesh. During baking, the flesh turns a yellowish color that becomes ultra rich and creamy. Their flavor is very different from the squash-like Garnet and Jewel varieties. It’s still sweet but more like a mashup between a russet potato and a parsnip.
 
WHICH IS THE BEST FOR BAKING?
Like most food things, it’s gonna come down to your personal preference but the Hannah, Garnet, and Jewel varieties are always good bets for cooking tasty baked sweet potatoes.

Okay, so you’ve got your perfect sweet potatoes selected. Now, there’s just one more thing you’ll want to know about…

A Sticky Situation

During baking, most sweet potatoes ooze a sticky sap.  Don’t worry, it’s completely normal.

But the sap does present a few problems:

  • It can seep under your sweet potatoes and make the bottoms soggy.
  • After 45 minutes to an hour in your 400-degree toaster oven that sticky sap may burn on the pan.

WHAT TYPE OF PAN SHOULD I USE?
First let’s talk real quick about what not to use, namely glass baking dishes. That’s because most manufacturers warn against using them in a toaster oven. Related: 4 Surprising Things I’ll Never Use In Our Toaster Oven

We’ve had success baking sweet potatoes in our large stoneware Le Creuset baking dish, in a dutch oven, and even in a cast iron pan. 

To get the most evenly baked sweet potatoes that don’t have bottoms covered in gooey sap we rely on three things:

For Smaller Toaster Oven’s like our little Oster, you can lightly oil the pan that came with it or use this Chicago Metallic Toaster Oven Baking Set (affiliate link).

Toaster Oven Baking Set with small rack and pan

The set has a mini rack and pan that will accommodate two large sweet potatoes, fits in most small to medium-sized toaster ovens and is also awesome for cooking super fluffy crispy skinned toaster oven baked potatoes.

Unfortunately, we haven’t found a silicone baking mat small enough for this pan set…yet.

If you have a Large Toaster Oven like our Breville Smart Oven Pro (BOV845BSS) a rimmed 1/4 sheet pan (affiliate link) with an oven-safe baking rack (affiliate link) works great.

Quarter Sheet Pan with Rack

For easier “sap” cleanup, you can line your pan with a small silicone baking mat, they come in a toaster oven size and a slightly larger quarter sheet pan size too.

 Toaster Oven Tip

* Check your manual before using foil to line your pan.

Manufacturers have specific instructions regarding the use of foil in their toaster ovens, so always make sure to consult your manual before using foil in your toaster oven.

Never put foil in the bottom of your toaster oven. Placing anything near the heating elements is dangerous and can cause a fire.

 

How to Bake Sweet Potatoes In A Toaster Oven

Start by adjusting the cooking rack in your toaster oven to the lowest position and preheating it to 400°F on the “Bake” setting.

Then insert an oven-safe rack inside of a rimmed toaster oven baking sheet.

Next, grab two sweet potatoes.

Raw sweet potatoes on pan

The sweet potatoes pictured above are from Costco so they were a whopping 16 ounces each! Unless you’re sharing with my husband Tim, yours don’t have to be so beastly.

Small (5 to 7 ounces), medium (8 to 12 ounces) or large (13 to 16 ounces), any size spuds will do.

With caked-on dirt and other fun oddities, sweet potatoes can look pretty gnarly straight from the farmers market or grocery store. Store them in a cool dry place (not your fridge) and then when you’re ready to bake them, toss your spuds into the sink for a good wash and scrub.

Dry each sweet potato well with a kitchen towel and then stab them once or twice on each side with a fork or sharp knife.

Note: Stabbing Is Optional

Some people don’t do it at all. We always err on the side of caution and so far have never had to clean an exploded sweet potato off our toaster oven.

Next, rub the potatoes with a little oil and place on the prepared rack or baking pan.

Place the pan in your preheated toaster oven and bake the sweet potatoes until a knife slides easily into their sides, about 40 minutes to 1 hour or more depending on their size.


Bake Them Your Way

There are hundreds of time and temperature combos for baking sweet potatoes that work out just fine.

Don’t stress, it’s really hard to make them wrong.

This way works for us, but your go-to way should be based on what works best for you and your little oven.

If you think 400 is too high, lower the temperature to 350 or even 300. Those spuds will taste fantastic and you’ll have less of a burning sap problem too.

Just remember, the lower the temperature the longer it will take.


Once the sweet potatoes are ready let them rest for a few minutes before handling.

Slice a line across the top of each one, push the edges towards the center to puff them up and use a fork to fluff the interiors.

WHAT ABOUT CONVECTION TOASTER OVENS?
Sweet potatoes cooking inside a convection toaster oven

We’ve baked sweet potatoes a few times in our Breville Smart Oven Pro (BOV845BSS) with the temperature reduced to 375°F and convection fan on. Each time it took about 40 to 45 minutes to cook sweet potatoes weighing between 7 and 8 ounces.

So, they didn’t bake any faster than a conventional toaster oven though they did seem a little creamier.

During baking, we needed to flip the potatoes halfway through the cook time as the top of the sweet potatoes were over-browning.

Because of this, we’d stick with a temperature of 375°F or lower when using the convection setting or a convection toaster oven.

TIPS FOR GETTING YOUR PANS CLEAN
Don’t wait to soak your pans.

Once you’ve got your sweet potatoes on the plate get your pan, rack, and silicone baking mat(if using) covered in hot water. Below is a picture of our baking rack and mat after baking a batch of sticky sweet potatoes.

COOK FASTER SWEET POTATOES
Like baked potatoes you can cheat and use the microwave but nothing beats the flavor and texture of a creamy baked sweet potato.

If you’re craving a baked sweet potato but don’t have an hour to spare, check out these Quick Baked Sweet Potatoes, or give these Addictive Roasted Sweet Potato Rounds a try. They take about half the time and taste delicious.

However you top them, we hope this guide helps you enjoy a warm and comforting batch of toaster oven-baked sweet potatoes anytime, not just during the holidays.

  1. Sure glad I read your post before baking that sweet potato. I had washed it and put it in the toaster oven like I’d do with a russet potato, then thought I’d better see if there was something I needed to know. And there you were, telling me what to do. So I went and did it. If you hadn’t shared about putting it on a rack and pan, my toaster oven would have been a real mess! And the potato turned out perfect. Thank you, thank you, thank you!

  2. I don’t use any oil. All your instructions have oil. Why is it important? If I don’t use any oil, do you have different instructions?

    1. Hi Laurel,

      We eat the skins on our sweet potatoes. The oil helps them to crisp up and taste yummy. Without it, I find the skins are a bit leathery and unappealing.

      If you’re planning on eating just the interior of the sweet potato or don’t mind the texture of the skins then you can skip the oil. It’s really more of a personal preference.

  3. I’ve been baking sweet potatoes in my toaster oven for years… in a foil pan, to catch the inevitable drippings.
    I recently got a Cuisinart toaster oven, convection oven, air fryer combo…. if I convection bake my sweet potatoes in this appliance, is it safe to continue to use a foil pan… or to set the potato on a sheet of foil to minimize the mess? Thank you!

    1. Hi Beth,

      Congrats on the new oven! When it comes to foil, every manufacturer has different directions so you’ll want to check your manual for instructions.

      I’m not sure which model you have as Cuisinart makes a few Air-Fryer Ovens but if you have the toa-60 model they have instructions for using foil on page 5 of the manual under the General Guidelines. They also have a FAQ page that has lots of good info, you can find it here: https://www.cuisinart.com/manuals/airfryers/toa-60.

      If that’s not your oven, I’d suggest contacting Cuisinart for an answer, that way you can enjoy baking your sweet potatoes without any worries 🙂

  4. This is my first stab at using a toaster oven.I havnt made anything yet and am looking for recipes to make.In fact it’s still in the box.I hope they have a recipe book in there somewhere. Any good recipes out there for me to do the first time.

    1. Congratulations on your new toaster oven Bernie!

      If the box doesn’t include a recipe booklet with the manual you might want to check out the manufacturer’s website. A lot of manufacturers have been adding toaster oven recipes to their sites.

      Baked sweet potatoes or baked potatoes are great starter recipes but if you’re a sweet potato fan I’d recommend our roasted sweet potato rounds instead they take about half of the cook time and are easy to customize.

      A few other simple and yummy recipes you might like are tortilla pizzas, roasted Brussels sprouts and classic pizza bagels.

      Bon appetit 🙂

  5. Thanks guys; this is Kenny and I’m in the process of buying a toaster oven, and this is going to get me off to a good start…
