Comparison: Best 42L Microwave (Updated | Dec 8th)

Consider the size of your family and the typical dishes you prepare; a 1.6‑2.0 cu ft model comfortably fits a 13‑inch pizza and larger casserole dishes, while a 1.1‑1.2 cu ft unit is better for singles or couples. Larger capacities often come with bigger turntables, which improve cooking uniformity. If space is limited, choose a compact model with a footprint under 20 inches wide. Balance interior volume with countertop space to avoid overcrowding your kitchen.

Inverter technology, found in the Toshiba ML‑EM45PIT, delivers continuous power levels for more even heating and better texture, especially for delicate foods. Traditional microwaves use stepped power levels, which can cause hot spots and overcooking. While inverter models may be slightly pricier, the improved cooking results often justify the extra cost.

Sensor cooking automatically adjusts time and power based on food moisture, reducing guesswork and preventing over‑cooking. Preset menus, like the 6‑menu options on Toshiba and GE models, streamline common tasks such as popcorn, pizza, or defrosting. If you frequently reheat or cook standard items, these features add convenience and can save time, making them a valuable upgrade.

A two‑step child lock, present on most Toshiba and GE models, prevents accidental activation and adds a safety layer for families with young children. Some lower‑priced units may omit this feature, which could be a safety concern. If you have kids, prioritize models that include a reliable lock, even if it means a modest price increase.

Higher wattage, such as the 1250 W output on the Toshiba ML‑EM45PIT, generally cooks food faster and offers more precise power control. Models ranging from 900 W to 1200 W are adequate for everyday reheating, but heavy‑duty cooking like defrosting large roasts benefits from higher power. Evaluate your typical cooking tasks to match wattage with performance needs.

The Toshiba 8‑in‑1 combo adds air‑fry, bake, grill, and convection modes, allowing you to replace a separate countertop oven or air fryer. This multifunctionality can save countertop space and provide healthier cooking options with less oil. However, these units tend to be bulkier and more expensive, so assess whether you will use the extra functions regularly.

A larger turntable (13.6‑inches on Toshiba models) accommodates bigger dishes and promotes even heating. Position‑memory turntables, like the one on the Toshiba ML‑EM45P, return to a preset spot after opening, reducing the chance of spills and improving safety. Both features enhance cooking consistency, especially for irregularly shaped foods.

Compact microwaves, such as the GE 0.95‑cu ft or Toshiba ML‑EM09PA, occupy less countertop space and are ideal for dorm rooms, RVs, or small kitchens. While they have lower wattage and smaller interiors, they still provide essential functions like sensor cooking and child lock. If you prioritize space savings over large‑dish capacity, a compact unit delivers good value at a lower price point.
