A published interior in liters, with French doors
Oster Extra Large 42 L French Door Countertop Toaster Oven, 10-in-1
42 liters, stated as a number rather than an adjective, behind doors that open outward from the middle. That combination — big, measurable, and easy to reach into — is unusual under two hundred dollars.

What it gets right
- 42 liters published as a figure — roughly 1.5 cubic feet, larger than any Breville here
- French doors clear far less counter in front than a single drop-down door
- Air fry included without the price jumping into Breville territory
What it doesn't
- No published wattage from Oster, so we show no running cost
- A 42-liter cavity takes longer to come up to temperature than a 25-liter one, whatever the element does
- Two doors, two hinges, two latches
What it costs to run
Oster publishes no wattage for this oven in any document we could find, so we do not show a running-cost figure for it. We are not going to estimate one from a similar model. Here is the method we would have used.
Skip this if…
…most of what you cook is for one or two people. The whole efficiency argument for a countertop oven is heating less air, and 42 liters is a lot of air.
No buyable offer at the last price check (Aug 8, 2026). We show nothing rather than a stale number.
