Questions & Answers

Service & Support

Oster® Extra Large Countertop Oven is rated 3.5 out of 5 by 73.
Rated 1 out of 5 by from Design flaw maybe My fiance and I had a smaller Oster toaster oven and upgraded to the TSSTTVXXLL and were happy with it for a while, until the timer knob decided to continue ticking away and not shut the oven off until we unplugged it. Contacted Oster and they immediately sent a replacement. Oven worked good for less than a year and the timer knob is doing the same thing all over again. We have to unplug the oven to make it stop ticking.... Not so sure that I want to go through with contacting Oster again to see if they are willing to replace another unit or just trash this one and search for a better unit, they obviously have issues with the timers on these models...

Rated 4 out of 5 by from Great for baking! This oven is large enough to bake 24 cupcakes perfectly. The turbo convection feature helped all 24 cupcakes bake evenly. The convection feature helps shorten the cooking time on roasting meat and poultry also. This oven has been used in place of my regular stove / oven since we got it. Everything from homemade lasagna and frozen pizza comes out well!! I can't forget to mention how well it toasts also. It beats my pop up toaster any day. My only complaint is the temperature dial settings are hard to read and it is difficult to set the exact temperature. *Disclaimer- I received this oven as a sample to review.

Rated 5 out of 5 by from Wonderful alternative to a full oven. The product had a large enough capacity to allow for preparation of multiple items for a holiday meal alongside a regular oven. The product was large enough to prepare most items, yet small enough to fit onto a countertop.  Having a second oven in a smaller size kitchen without sacrificing space was a tremendous benefit. The convection feature allows for an oven baked flavor in a fraction of the cooking time (as opposed to a less than full flavor you sometimes get from a microwave oven). Baked items such cookies or brownies also came out wonderfully. DISCLAIMER: I received this product as a sample to review.

Rated 5 out of 5 by from Fantastic oven! Disclaimer: I received this item for free in order to give an honest review, which is what I'm doing. I used this product for over a month and I genuinely love it. It works great and is easy to clean. The baking feature cooks better than my oven! The turbo feature is also very impressive. I cooked baked potatoes in 40 minutes (instead of an hour) I have absolutely loved this oven. Remember that this is a large oven and it does take up quite a bit of space. It's several inches longer and wider than our microwave. The only con is the plug. It's short and on the right side. My outlet was on the left. It barely reached. You might need an extension cord unless it's very close to the outlet.

Rated 5 out of 5 by from Well Designed! This was my 1st Oster small appliance purchase. It will not be my last. I have used large countertop convection toaster ovens for decades. I like the economy of heating a smaller space (suitable for all except the largest projects) and using 110 power vs 220 in my daily cooking to bake, broil or toast items smaller than 20 lb turkeys. Many models will fit a standard Lodge 10" cast iron skillet, but the Oster TSSTTVSSLL accommodates the Lodge 12" CI skillet (including handles) on its sturdy racks. My only suggestions for improvements: 1. Add another set of slots for the oven rack, higher in the cooking area, to put the food closer to the broiler to quickly toast a sandwich; 2. Add the turbo fan option to the broil setting; and 3. Add an interior light. THANKS!

Rated 4 out of 5 by from A time and energy saver! I have been using this Oven for a month. Size does matter when we make large pizzas, bread etc., and it scores well. It preheats and cools off a lot quicker than my regular oven. It cooks all food (Pizza, Cake, Casserole, Cookies, Brownies, Bread, Lasagna) quickly and browns evenly. All came out very well compared to my regular oven. I stopped using my regular Oven after I started using this oven. I would have given 5 stars if it had digital controls to keep things simple for everyone instead of the dial settings. DISCLAIMER: I received this product as a sample to review.

Rated 4 out of 5 by from Hinges need work The toaster oven is very large. for a standard depth countertop this could be a problem because the glass door slams the edge of the countertop. If the hinges were redesigned to slowly open it would keep from slamming. Or just remember to be very careful when opening. Next to the timer you will notice it says "turn to 20 and then to desired time." This is key or else the oven will stop in mid cooking without a beep. I thought the oven might be defective, but found the message. Cooks great.

Rated 5 out of 5 by from Convenient Countertop Oven I have been very pleased with the Extra Larger Oster Countertop Convection Oven. I have found myself using it in place of my conventional oven. The design is nice as it is made out of stainless steel and looks nice on the countertop. The Oster Extra Large Oven is much larger than a traditional toaster oven so if you have minimal counter space you may want to go with a smaller Oster toaster oven. The rounded back accommodates larger traditional size cookware and bakeware. The controls are rounded and easy to use. There is a timer function that works nicely as well. The Oster Extra Large Countertop Oven cooks as well as my standard kitchen oven. If a microwave oven was included in this model it would be the only cooking appliance I would need. The top of the oven gets hot. Consequently, I use the top of the oven to heat my plates prior to serving. Dinner has been hot, convenient and easy. Great job Oster. I love this product and thank you Oster for providing this oven as a sample product to review.
