Oster is a well-known face in the game, and they have a lot of offerings. I chose this one in particular because it has become the pinnacle of what I see as peformance per dollar. Read below why.

Oster TSSTTVMNDG Toaster Oven closed on a counter.

At the time I got the Oster, I was pretty annoyed at the fact that my kitchen really lacked the space for me to properly get around. My wall oven was old and a pain to use – it always acted up and never quite baked evenly. The countertops were constantly cluttered, and I really didn’t mind having a few extra cupboards. 

You know how it is, though. I wasn’t going to remodel the entire kitchen just to make it a bit more spacious. Instead what I did was to search for ways to make cooking a little more convenient, and through a recommendation from a friend, I stumbled upon the Oster Digital Toaster Oven.

I won’t lie, I was skeptical. I did use to own a tiny Black&Decker once, and it seemed like it’s the type of thing you use in college to warm up last night’s pizza instead of making a proper dinner — something tiny and not very useful. I never would have thought this surprisingly large appliance would come to basically replace my nemesis of an oven. (And yes, it can bake pizza too — a full six slices.)

This toaster oven helped me keep my family of four fed — I don’t ask for a lot more than that, but that’s not even the end of it. Here are a couple of reasons why I personally really liked my Oster Toaster Oven.

Big Enough for a Family, Small Enough for a Countertop

The Oster toaster oven looks quite unassuming at first glance. It doesn’t seem as large as it really is. I’ve had no issues fitting it nicely onto one of my aforementioned ever-cluttered countertops. That’s why when I first opened the package and took a proper look at it, I was — once again — rather skeptical about just how useful this oven would turn out to be.

Needless to say, I was wrong to doubt.

This Oster model measures 19.72 W x 16.29 D x 11.33 H inches, and once you open it up, you’ll see what that really means. It’s kind of shocking how spacious this thing really is on the inside! Oster really took care to make the most use out of the size, and as such, for the same amount of space taken, you get more room inside for your cooking needs.

Keep in mind, between my husband, myself and two kids, we’ve got four mouths to feed — we needed something that will fit a meal for all of us! If you’re like me and you don’t have an eye for measurements, I will tell you some of the meals I was able to prepare in this large toaster oven.

  • 12″ pizza – Oster TSSTTVMNDG is spacious enough to allow me to bake a large, six-slice pizza. 
  • Casseroles – I’ve already prepared countless delicious casseroles in the Oster. The largest dish with handles that I was able to fit in was an 8×11, which is more than enough for a lot of families.
  • Lasagna – using the same casserole dish as above or anything else you’ve got at home, you can make yourself a mean lasagna.
  • Baked sweet potatoes – my daughter goes crazy for these, and they’re super easy to make in the Oster.
  • Toasts – a favorite with both the adults and the kids, I love making toasts in the Oster. It’s easy to make them as crispy as you like.
  • Bruschetta – who doesn’t love these? Thanks to the broiler setting on this oven you can melt parmesan on your bruschettas without any issue.
  • Cakes – Yes, I have successfully baked cakes in this toaster oven! I find it easier to adjust the temperatures and the cakes come out perfectly.
  • Roasts – I love roasting, as it’s a healthy but delicious way to prepare meat, veggies and more. This oven has done a fantastic job of roasting everything I’ve tried so far.

That’s just a short excerpt from the list of things I’ve used the Oster for, but none of it would be possible without the large interior with two rack positions. That was a huge selling point for me and also the reason why I recommend it to my friends.

Ease of Use

We’ve all had an appliance, big or small, that was just a nightmare to use. Be it an overly complex microwave or a badly designed blender, we’ve all been there. My previous experience might be part of the reason why I really like how easy to use the Oster is. Don’t mistake “easy to use” for “basic” though, because I don’t think anyone could turn their nose up at the number of settings this large toaster oven boasts.

The first thing you’re going to notice is the keypad. A lot of toaster ovens don’t have one, and they really should — this is so much easier to use! Using the keypad allows for a precise selection of temperature and cooking settings.

Sometimes you won’t want to do it all by yourself, and that’s alright too. The Oster comes with a couple of pre-set functions, such as the pizza function which is a default 20-minute run with a 400°F temperature. 

All of the settings on the keypad include:

  • Toast
  • Bake
  • Convection Bake
  • Broil
  • Warm
  • Defrost
  • Pizza

You can also easily adjust the time and temp using plus signs. Below all the cooking settings are two very handy functions: the clock and the light. Of course, it’s the light that stands out to me in this model and once again makes me compare it to a full-sized oven. 

You don’t often see an interior light in toaster ovens, but it does make cooking a lot easier. It helps me control the cooking process with ease and allows me to reach the right level of browning.

One more thing: Oster has an excellent collection of How-To videos for their toaster ovens. Check them out!

Temperatures That Can Rival an Oven

I mentioned the range of temperatures briefly above, but I want to go more into detail because they’re another point the Oster has won me over on. You don’t really need a full-size oven anymore — or at least I don’t — when using this convection oven.

The temperatures in this model range from 150 to 450 degrees Fahrenheit. I have successfully used it for roasting, baking, broiling, reheating, toasting, and more! It’s a pretty powerful 1300-watt oven, so it can really put up a fight against traditional ovens.

In the convection mode, the Oster circulates hot air – this is recommended for broiling, toasting, and roasting, and I fully agree. Using the convection mode I was able to really up the ante on my cooking. The edges are deliciously crisp, the browning is even, and the roasts turn out juicy – never dry.

Quick and Easy Cleanup

I’m sure that most of you have a microwave, and maybe even a long list of other appliances that are meant to make life easier. I do too, and I’d be lying if I said that they don’t help, but the cleanup after cooking is often a pain.

Too many appliances come without removable trays, meaning they’re never fully clean, because how do you reach and scrub every nook and cranny when you can’t even see where the dirty surface is? In comes the Oster with yet another good addition – a removable crumb tray. 

Like anything else, if you allow grime to build up, you will still have to use some elbow grease to fully clean this toaster oven. I try to remove the tray after every use, and I remind my husband to do the same because it makes things much simpler. The cleanup is painless and takes less than a minute. Lastly, all the accessories are dishwasher-safe — for real. I’ve tried and tested it and had no issues (which is not always the case with many appliances or dishes).

Surprising Convenience

I realize that, by this point, this probably sounds like a love letter to a toaster oven, but honestly, I could write one if I knew that someone would read it. The Oster has saved me many hours and helped me prepare many, many meals. For that, it has truly earned its place in my kitchen… so I will talk about a few more of the things that I enjoy. The last points I want to make are related to the safety of use and the general convenience of this toaster oven.

The Oster TSSTTVMNDG is very simple to use, but it’s also remarkably safe. It has a 60-minute timer that shuts it off when it’s not being used. If you’ve ever forgotten to turn something off at a crucial time, you will be grateful for it. I know it has already saved my hide at least once, as I don’t like to leave things on and let them drain electricity for no reason — not to mention the fire hazard!

It comes with two rack positions that can be adjusted according to your needs. I haven’t had many issues with something turning out burnt, at least not after the initial period of adjustment, and that’s largely due to how adaptable this oven is.

Last but not least, I enjoy the fact that the timer is loud – like a microwave or even more so. If you’re microwaving a snack in the middle of the night you may hate the timer on them, but for me, the Oster allows me to go and do something else while preparing dinner — and that’s a win in my book.

The Good and the Worse

I think I’ve talked about how much I love the Oster at length, but I’m not a salesperson — I’m not going to try and pretend that it’s perfect. Nothing is. For me, the Oster comes pretty close, but I’m going to let you make up your mind and list some of the pros and cons of this toaster oven.


  • Large interior – large enough to keep a family of four well-fed. 
  • Space-efficient – I realize that this somewhat counters the former point, but the upside of the Oster is the large interior compared to a moderately-sized exterior. It will fit on any countertop.
  • Versatility – the list of things I’ve used this toaster oven for is long and it just keeps on growing. You can prepare a pizza, lasagna, cookies, cakes, roasts, casseroles, snacks, nachos, and so much more.
  • Ease of use – the pre-set settings and the use of a keypad rather than a dial make for a very user-friendly appliance.
  • Interior light – this is great for judging when your meal is ready, and it’s not a feature often found in toaster ovens.
  • Cooking – this thing cooks, bakes, roasts, broils, grills, defrosts, and toasts, and it does it well. The 150-450 degree Fahrenheit temperature range and the convection mode are both things I take advantage of often.
  • Oven & microwave in one – I find myself rarely using the oven and the microwave since I’ve gotten the Oster. It combines the features of both into one pleasing package.
  • Price – for the number of features this oven comes with, I honestly expected a much more hefty price tag.


  • Toasting – this setting took me a bit of getting used to. It goes from a low of 1 to a high of 6. Using higher settings sometimes resulted in burned toasts where I expected them to be crispy.
  • No light-up controls – it could just be me, but I would like the keypad to be lit up. It’s hard to discern one setting from another without the light on.
  • Settings – while I love all the different settings, I freely admit they take some time to get used to. I recommend underestimating the time it takes to cook things and add on as needed until you’re comfortable with the timing.


If you’ve been following me at all, you know I’m not a person that is easily convinced. It wasn’t love at first sight with the Oster — it never is. But looking back on all the good and the bad things I do still recommend this particular toaster oven to my friends.

It’s powerful, space-efficient, and remarkably versatile. It has a lot of settings that make it simple to use. I didn’t use all of them on a daily basis, but I have tried them all, and they encouraged me to experiment in the kitchen just for the sake of trying them out. I especially loved the broiling and the convection baking, and I was getting used to toasting is growing on me, although it took some time.

For all the good that it brought to my then-smallish kitchen, it was surprisingly cheap, and it was saving me time and money as I mostly used the Oster rather than the wall oven. If I had to make do with just this toaster oven and a microwave for a whole year, I may not have even noticed.

If you’re looking for a large toaster oven that’s easy to use but impressively equipped, I can honestly tell you to give the Oster TSSTTVMNDG Toaster Oven a try — I’m glad that I have.

But I’ll let you be the judge, it’s pretty inexpensive on Amazon. Click here to try it for yourself.
