Overview
The Hamilton Beach Professional 31240 is a large 6 slice convection countertop toaster oven with a built-in temperature probe, bake pan, broil rack and stainless steel finish, sized to fit a 12 inch pizza or a whole chicken.
This unit is pitched as a stand-in for a full oven rather than a basic toaster, with 7 cooking settings, 3 rack positions and a probe that tracks internal meat temperature as it cooks. It backs that up with a 3 year limited warranty. The main friction point owners raise is the button-based control scheme rather than a dial, and a cord that can overheat if it rests against the back panel.
- Built-in temperature probe with storage drawer
- 7 cooking settings including convection
- 3 rack positions
- 17 x 23 x 14 inch stainless steel body
Who it's for
Suits someone who wants a genuinely oven-sized countertop unit with a meat probe for roasts and casseroles. Less suited to anyone who wants simple dial controls or a compact footprint, since this measures 17 by 23 by 14 inches.
Pros and cons
- Fits large pans like a 9 by 13 dish or a 12 cup muffin tin
- Temperature probe tracks meat doneness during cooking
- Preheats quickly and bakes evenly per multiple owners
- 3 year limited warranty backs the unit
- Plus and minus buttons instead of a temperature dial
- Cord can overheat if it touches the back panel
- Toast mode runs slower than expected
- Large footprint needs real counter space
Performance notes
The convection fan circulates heat for even baking and broiling, and the digital display tracks oven temperature alongside the probe reading to reduce overcooking. Three rack positions and the 7 cooking modes cover toast, bagel, bake, broil, warm, reheat and convection.
