Buffet Server Roaster Oven | Oster Roaster Event Maker

A buffet server is principally a warming tray with separate sections from which you can serve various warm foods to your guests. You can hook it to your roaster easily, and offer three different meals or side-dishes. Many companies produce buffet servers as attachments for their roaster ovens. However, most kitchen enthusiasts prefer the Oster Roaster’s version, which you can attach to the 18 Quart model. The company made a well-deserved name for itself on these specialty trays over the years.

You can arrange your dining room as an open buffet bistro with a snap, even if you don’t like to cook. Get some frozen food, warm in the microwave, and serve on the buffet tray to your friends. Hosting events could not be any simpler. Besides, you can use your roaster oven for making various meals. Stews, turkey roast, prime ribs, and ham are just a few to mention. Once you remove the food, attach the buffet tray to serve the side-dishes on it.

How to use a roaster oven buffet server?

Should you put stuffing inside the turkey?

If you ask me, I would never recommend to put stuffing inside the turkey as it can easily get contaminated. Even if you slightly undercook the turkey, the stuffing can produce dangerous bacteria. Why would you take the risk? You can still prepare the rice stuffing on the stovetop. Add some broth if you like. It should come out very close to the stuffing that is cooked inside the turkey. Trust me; it tastes much better since you get more control during cooking. If you really want to put something in there, then add the following to spice up the turkey roast.

For a 16 to 18 pounds of whole turkey:

  • 2 green apples cut into wedges
  • 2 medium size onions cut into four
  • 1 orange cut into wedges
  • 1 lemon cut into wedges
  • 2-3 rosemary stems
  • 2-3 garlic cloves cut into halves

Still, please do not eat them but use them as aroma enhancers.

Tip Alert

You can improve the moisture during cooking by adding sliced apples inside the turkey. It is a great trick to cook a juicy bird.
