An Oster electric roaster oven is a countertop cooker that roasts, bakes and slow cooks in a deep removable pan, freeing your main oven for sides and desserts. For most holiday tables and game-day spreads, the 18-quart size handles a turkey up to 22 pounds, while the 22-quart model stretches to 26 pounds and bigger batches of chili or pulled pork for a crowd.
This article compares three Oster roasters: the CKSTRS18-BSB-W 18-quart model in black, a second 18-quart roaster sold under model 072-10-0379, and the 22-quart stainless steel roaster with a self-basting lid. All three use a self-basting lid design. They differ in capacity, how much detail each listing gives and warranty length. We compared listings, specifications and intended use to size each roaster to your bird and your guest list, without claiming hands-on cooking tests.

Best for
Holiday hosts roasting up to 22 lb
Pros
- Fits turkey up to 22 lb
- Self-basting lid
- Enamel-on-steel pan and rack
- 2 year limited warranty
Cons
- Spec sheet lists odd extras
- Dimensions not listed
The Oster CKSTRS18-BSB-W 18-Quart Roaster Oven is the black 18-quart model and the best-documented of the two 18-quart options. Oster says it roasts a turkey up to 22 pounds, and its self-basting lid uses steam from cooking to keep food moist, cutting out the need for constant hand basting. The lid also helps hold heat in, which the listing says speeds cooking.
It includes a removable enamel-on-steel roasting pan for even heat and easier cleanup, plus a steel roasting rack. The listing says it bakes anything a regular oven would, from muffins and yeast rolls to a full sheet cake, and the description mentions variable temperature control. That flexibility is useful when you want wings in the main oven and dessert baking on the counter during halftime. It carries a 2-year limited warranty, the longest of the three.
Think of this model as the dependable all-rounder. On a holiday it handles the bird; the rest of the year it can take on a big batch of meatballs for a tournament night, a tray of baked ziti or a slow-cooked roast that sits quietly while everyone is glued to the screen. The black finish is the main visual difference from the stainless 22-quart model.
The spec sheet is messy in places. It lists a crumb tray, a dropdown door and a rotisserie feature, which do not match a lidded roaster design described elsewhere in the listing. Treat those as listing errors. The listing also does not specify dimensions. This model suits hosts cooking for a typical family holiday; it gives way to the 22-quart model for birds heavier than 22 pounds.

Best for
Cooks wanting a basic 18-quart roaster
Pros
- Room for a 22 lb turkey
- Self-basting lid
- Knob temperature control
Cons
- Very thin listing details
- Hand wash noted in title
The Oster 18qt Roaster Oven sold under model number 072-10-0379 covers the same basic job as the CKSTRS18 model. Its description says it has room for a 22-pound turkey, a self-basting lid to speed up cooking and a removable roasting pan that is easy to clean. It can roast, bake, slow cook or serve, and a knob control sets the temperature.
The listing is thin. Its only feature bullet says it is brand new in box with all relevant accessories, and the included components line lists a baking pan, a sheet pan and a user manual, while the description refers to a removable roasting pan. The listing does not specify a rack, dimensions, color, wattage or warranty length, and the title notes hand wash for care. If you are comparing it against a countertop cooker for everyday meals, our guide to an Oster countertop oven shows where a smaller appliance fits better.
The serve function mentioned in the description is worth noting for parties. A roaster can double as a warming station on the buffet table, holding pulled pork or chili at a steady temperature while guests help themselves between matches. The listing does not describe a dedicated warm setting, though, so rely on the knob and keep an eye on the food.
This roaster suits cooks who want an 18-quart unit and do not need detailed specs up front. It gives way to the CKSTRS18-BSB-W if you want a listed warranty and a clearly described rack, and to the 22-quart model for larger birds.

Oster Roaster Oven with Self-Basting Lid

The Oster Roaster Oven with Self-Basting Lid is the 22-quart stainless steel model, listed as CKSTRS23-SB. It is the capacity champion here: the high-domed lid fits turkeys up to 26 pounds, four pounds more than the 18-quart models. For a big holiday table or a watch party with a long guest list, that headroom matters.
Its self-basting lid continually recirculates moisture, and an adjustable temperature dial lets you roast, slow cook or bake. The description adds a Keep Warm setting, which is useful when kickoff times shift and dinner has to wait. The removable enamel-on-steel pan and rack make cleanup easier. It measures 23.3 by 15.6 by 11.8 inches, so plan counter space before it arrives. If you are building a bigger outdoor menu too, an electric smoker with a digital control panel pairs well for low-and-slow meats.
The trade-off is warranty: the listing states a 1-year limited warranty, half the 18-quart CKSTRS18 model. It suits hosts feeding the largest crowds; it gives way to the 18-quart models for smaller kitchens.
- 22-quart capacity, turkeys up to 26 pounds
- Self-basting lid recirculates moisture
- Keep Warm setting
- 23.3 x 15.6 x 11.8 inches

NOTES
Buying Tips for Oster Electric Roaster Ovens
Size for your biggest bird. The capacity number matters most at the holidays, so pick the 22-quart roaster if you ever cook a turkey over 22 pounds. For everyday batch cooking, an 18-quart unit is easier to store and still big enough for large pots of chili or pulled pork.
Plan counter space and power. A roaster sits on your counter for hours, and the 22-quart model is over 23 inches long. Keep it away from walls and cabinets while it runs, and use a dedicated outlet where possible, since the roaster may share a circuit with other appliances on a busy cooking day.
Use the roaster to free your main oven. That is its real value on game day: the turkey or roast goes in the roaster, and the main oven handles wings, sides or pizza. If pizza is on the menu, our guide to an electric pizza oven is worth a look.
Check cooking times as you go. Countertop roasters heat differently from a full-size oven, and the self-basting lid traps steam, so recipes written for a wall oven may finish at a different pace. Use a meat thermometer rather than the clock, and avoid lifting the lid more than needed, since each peek lets out the heat and moisture the lid is designed to keep in.

Whichever capacity fits your counter, both appliances reliably take the pressure off your primary oven during large gatherings.
