Best Microwaves for Large Families: Capacity, Power and What to Look For

When you're feeding four, five or more people, an underpowered or undersized microwave quickly becomes one of the most frustrating appliances in the kitchen. Here's what to look for in a microwave that can keep up with a large family's daily demands.

Capacity: How Much Do You Actually Need?

Microwave capacity is measured in litres. For a large family, the right capacity depends on what you use the microwave for most:

• 25–30L — handles standard family cooking, fits most dinner plates, suits most households of 4–5
• 32–40L — fits larger platters and casserole dishes, ideal for households that frequently reheat in bulk or cook large portions
• 40L+ — family-size models that can handle a 2.5kg chicken, large baking dishes and multiple servings at once

For a large family, we recommend a minimum of 32L. If you regularly cook whole chickens, roasts or large soup pots in the microwave, go for 40L.

Wattage: Higher Is Better for Large Households

For large families, 1000W should be considered the minimum. At 1000W+, food heats faster and more evenly, which matters when you're feeding five people who all want hot food at the same time.

At 1100–1200W, large quantities heat more evenly, cold spots are reduced, and total cooking time is significantly less than at 700–800W. If you use the microwave intensively, the small premium for a higher-wattage model pays for itself quickly in convenience.

Inverter Technology: The Secret to Even Heating

Traditional microwaves cycle the magnetron on and off at reduced power settings. This means that at 50% power, the microwave alternates between full power and off — leading to uneven heating and hot spots.

Inverter microwaves deliver power continuously at the selected level. This means food heats more evenly, particularly in the centre, and delicate foods like fish and eggs are less likely to be overcooked on the outside while still cold inside.

For large families cooking full portions regularly, inverter technology makes a noticeable difference and is worth seeking out.

Combination Microwaves: More Versatility for a Big Kitchen

Combination microwaves add convection baking and/or a grill element to the standard microwave function. This turns the microwave into a secondary oven — useful for crisping, browning and baking in a fraction of the time a standard oven would take.

For large families that use the oven heavily, a combination microwave can take pressure off the main oven at peak meal times. It's particularly useful for:

• Crisping roast potatoes while the main oven handles the meat
• Baking a quick batch of biscuits or muffins without heating a full-size oven
• Grilling toast or reheating pizza with a crispy base

Turntable Size Matters

Check the turntable diameter as well as the internal capacity. A large internal cavity with a small turntable may still not fit a standard family dinner plate. Look for a turntable of at least 32cm for large family use — some models offer 34–36cm turntables that accommodate large oval dishes and casserole pots.
