Perfect Oven
This is the only oven I use - all of my baking dishes and pans fit. It is efficient and versatile, accommodates 12" pizza and yet does not take up much space on counter. Love, love my Oster oven, and NEVER use my standard oven because it is too big and inefficient.

Oven doesn't work right out of the box
Just bought this today, and right out of the box the elements don't work. One lights up red and the other on the bottom only gets warm and the one on the top only gets warm. I had this same oven before and never had this problem. I'm returning this tomorrow!!!

Love it

I purchased this counter oven after returning a different brand that was similarly priced. That one did not have a stay on switch like this. It allows me to turn on like a regular oven so I can let Preheat as long as I want and cook as long as I want. The other oven had a default timer that dictated how long I could use. The other turned off because it made you time and only to 90 minutes. This one with stay on mode is light, stainless and comes with many extra cooking items. Holds a 12"+ pizza and 9X13 pan.

Great buy.

Great oven, saves on heating up the larger oven.looks sleek a bit large but cooks most anything that the large one would.large pizzas . Makes House smell great ,when baking,the convection cooks baked goods perfectly.


If you love to bakeing but hate to heat up a big oven or the house This is the best thing ever! 9x13 pan no problem, medium pizza yea! cookies and bread Wow! Thank you soooo much for making this. LOVE It! Useing range oven for storage now days!

Best price you'll find on a great counter-top oven

So far I've been very happy with the oven. It's a vast improvement over the old GE counter-top oven I've been using. The convection feature is handy. It's big enough to cook almost anything but the big thanksgiving bird. I recommend buying the oven.

Thank you for the awesome review! We work hard to meet expectations like yours and we’re happy to hear we hit the mark for you. If there's anything that we can do for you, please do not hesitate to contact our customer care team at 1-(800) 334-0759. For your convenience, we are available Mon-Fri 9am-6pm, EST. Thank you for being part of Oster!

Love my new appliance!

Big enough but not too big, easy to operate, nice looking appliance! I baked chicken in it and I don't think I've ever had such moist and juicy chicken that wasn't on a grill!! Can't wait to try out the air fryer feature! Great item for a decent price!

Thank you for leaving such a nice review. We are glad that you love our product. We work very diligently and it will provide us greater encouragement to keep doing what we are doing. We will strive to deliver great experiences consistently. Thank you for being part of Oster!

Great to use in place of oven!

I only rated durability at 4 because I've only had it about 1 month. So I can't really tell on that yet. The price was good for the size and features. Walmart site-to-store was great. Love the rounded back that lets you cook a large pizza. My 9x13 fits great and I like the convection feature, something I've been wanting. But there aren't any real instructions for converting from regular oven to convection, regarding the time difference. Still, I'm working with it and it's doing ok. It has a feature called 'warm' which I assume means it will keep something warming for 30 minutes (or you can set for lesser time) but there are NO instructions in the booklet about WARM, and I'm not sure if that is going to be good. Still working with it. I wish I had more counter space -simply to keep the unit out from under the cabinet more - it warms up the underside of the cabinet a lot when I'm cooking, and the short cord doesn't allow for much positioning. I understand why the short cord (safety) but it should be a little longer. Otherwise, it cooks great and I love it so far! Love not heating the big oven up for casseroles, etc. ONE other thing- you can't cook past 1-1/2 hrs (90 minutes) - unless you adjust it when it's done to start again. It's not a slow cooker and you can't run off and leave it all day. So go use the slow cooker :D BTW, the broiler pan in the picture came with it, and it also has 2 racks and 2 rack positions (low and midway high) in the oven.

Good Value and well made for the price

What's Right about this product: This oven has a 16" opening - much wider than most. Maybe some people will regularly cook a 16" pizza in this oven, but 15 inch casserole dishes with "ears" for handling are more likely. So are standard 15" catering pans, and aluminum 15" pans that are commonly available in grocery, and big box stores. See picture. This oven replaces another "Large", commonly available, countertop oven, with a 14" opening. These containers simply did not fit in the old oven, and had to be transferred to a smaller pan. If you have ever tried to transfer a 15" lasagna to a 14" pan, you can imagine the mess that this oven avoids. It fits everything that we have or would buy. If it won't fit in this oven, it has to go in the big oven that requires 4 times the electric power. Electric power is another consideration. Most large ovens require 1800 watts, or ALL of a standard 15 amp electrical circuit. There is no power to spare, for even a can opener or hand mixer. This oven requires only 1500 watts and the circuit is not totally utilized to the exclusion of all other appliances. It still gets the job done with less power. It is Underwriter's Laboratories rated. This oven is mostly stainless steel, and is easier to clean as a result. Many, if not most, countertop ovens are painted, or powder coated, and the heat of the oven causes them to discolor. I'm an engineer, and the design and quality of manufacture is better than I would expect from an oven at this price. Exceptions are noted – but they are minor. I still earns a 5 star rating. What small things could be improved at minimal cost for the next design: 1. I wish that the oven had a third slide such that the wire grilles could be set another 2” higher for broiling. 2. This oven get's hot – hotter than most. Perhaps this is necessary to heat such a large volume, but insulation inside could improve things. The sides are ventilated, but care should be exercised to touch only the control panel and insulated handle of the door. 3. Because the oven is designed to accommodate a 16” round object – it protrudes about 3 inches out the back and the front of the oven is consequently 3” closer to the edge of the countertop. As can be seen from the second picture, this causes the door to contact the edge of the counter. One solution is to purchase essentially the same oven with French doors for twice the price, or protect the countertop. The next design could include an extension of the cast handle on the ends to touch the countertop, rather than have the hot glass touch the countertop. 4. Because it has a metal cabinet, I also wish that it had a 3 wire plug. 5. Perhaps the rear protrusion was removable, such that a flat panel would slide in instead, or that a model was available without the protrusion. If was not as deep, and I had to trim 1 ½ inches off two sides of a 16 inch pizza - No problem. It would still cook the pizza, but it would retain the critical 3” of counter space in front of the oven. 6. I wish that the removable drip pan were made of stainless steel. The bright metal that it has, works fine if covered with aluminum foil. Keep the foil away from the heating elements.

Love it

My oven have no problem since December 20 1918 purchased from Walmart store. Perfect fit 15 inch glass oven dish see pictures. But I am complaint there is no light hard for me to see dark inside.

It's a very nice oven but,

This oven is beautiful and it seems to work well.It's plenty big but I have two issues. The oven in the video is different than the one i got. it shows that the bake pan has its own rack, well it does not and also no red power light at the bottom. My bigger issue is the quality control with this oven as they applied the digital control pad all cockeyed and it ruins the ovens looks (see photo) These items are not deal breakers but I am not happy about it so I gave it an overall average rating

by doctorchristi
4. Yes, it came with 2 shelves. And I found cookie sheets that fit it. I waited until it was sitting in my kitchen. Then I measured how long and how wide a sheet would fit. Then I took those measurements and a measuring tape into the store. Watch out for the measurements printed on the cookie sheets in the stores - sometimes those measurements don't include rims and handles.
by SewMerrily
5. It is supposed to come with 2 racks but mine did NOT. I simply went to the Oster site and told them about it. I included the model and other info and in 2 days I received an answer from them. My second rack was on its way to me! Got it in less than a week and no charge!
by SwampCatNana
6. I bought mine April 2011 and it came with two shelves.

11. It has two racks/shelves and holds a 9" x 13" pan.
by Organizer3
12. comes with 2 racks plus a broiler pan similar to what you'd find in a gas oven, just sized to fit. normal sized pans fit, 15 inches and under in either direction.
13. Comes with two racks and a broiler pan. It will fit what most manufacturers call a small cookie sheet, generally in the 9x13 to 10x14 range.

1. Yes
by Mopsy
2. Yes! That's one of the reasons I bought it. If I have to use the big oven just because it's a 9x13 casserole, I just wasted my money!
by katanna05
3. yes it does. I tested at the walmart store. It fits w/ the handles facing the door. Not sideways.
by bowbei
4. no problem you could fit up to a 12 X 15 pan.
by Chicago45
5. Yes it will fit EASY, my plate is 11"x 14" edge to edge. The width on the Top Rack is 15-1/2" will hold my 2 inch deep baking pan that is 15" x 11". But at 15" wide the Depth from the front of the grill to the back will be 12-1/2 ". If the pan or plate is only 10" wide you could get as much as 14" Depth from the front to the back. The back of the oven is Oval (Rounded) so a Large pizza will fit and they do. Read my review.

6. Yes with a half inch to spare on the handles of a pyrex casserole dish.
by dWShasta
7. Yes, but not all 9 x 13 casserole dishes measure the same from end of handle to end of handle. The rack measures 15 3/4 so be sure to measure you dish. The dish I had measures 17 inches. I did find one at Walmart that was just under 15 3/4.
by ila123
8. Yes. Perfectly
by TwoSwan
9. yep ive done it
by jreezy
10. Yes, 15 inches and under fits in either direction.
by joefromtennessee

1. I have a 13x9 pan purchased from Wal-Mart and it fits just fine. The inside width is 15 3/4"
by TLBRomeShopper
2. Yes.
3. Yes there is plenty of room for a 9x13. just remember you need to have a Oven Therometer to hang inside. And when it is set on Convection it will OVER Cook Bread, Biscuits, Rolls quickly.
by beendownthatroadbefore
4. yes
by ooven
5. Yes, very easily
by Jenny1965
6. Yes it will. Without much space for the heat to circulate, though. I'd use the convection option with a 9x13, watching carefully towards the end of baking time.
by L8989
7. This Oster oven will hold a 9 x 13 pyrex casserole dish, a favorite size for a family meal. It will also bake sweet potatoes in their jackets using the convection function. Just be sure to wrap them in foil so they don't leak the juices. Even if the juices leak, the stainless steel crumb tray catches the baked on refuse and it cleans up well.
by Zmain1
8. Yes, but be sure to measure the dish first. The casserole dish I had measured 17 inches from end of handle to end of handle. Way too large. The rack measures 15 3/4. I did find an Anchor Hocking 9 x 13 dish that measured just a hair under the 15 3/4 at Walmart. It fits just fine.
by ila123
9. Yes. 16 inches is too big, 15 and under fits fine.
10. Yes. Rack size is 15.5"x13", with an extra bulge in the middle back which gives the center a depth of almost 16". That accommodates round pizzas.
