Quick Answer
The time needed to roast tomatoes in the microwave depends on several factors, including the quantity and size of the tomatoes, the power level of the microwave, and personal taste preferences for roasted tomatoes. Generally speaking, it takes 3-8 minutes to roast cherry or grape tomatoes cut in half, 6-12 minutes for larger tomatoes cut into 1-inch chunks, and 8-15 minutes for whole medium tomatoes. Roasting times may need to be adjusted based on your particular microwave. Watch tomatoes closely as they roast and stop microwaving when they reach your desired level of roastedness.
Calculating Microwave Roasting Times for Tomatoes
When determining how long to roast tomatoes in the microwave, there are a few key considerations:
Amount and Size of Tomatoes
The more tomatoes you are roasting and the larger they are, the longer the roasting time. Smaller tomatoes like cherry and grape tomatoes cut in half take less time than larger chunks or whole tomatoes. Here are some general guidelines:
– Cherry/grape tomatoes cut in half: About 3-8 minutes
– Diced or chopped tomatoes in 1-inch chunks: 6-12 minutes
– Medium whole tomatoes: 8-15 minutes
– Larger whole tomatoes: 10-20 minutes
Roast tomatoes in a single layer on a microwave-safe dish to ensure even cooking. For larger batches, work in multiple rounds.
Power Level of Microwave
Microwaves vary in their wattage and power levels. Lower wattages and power levels will require longer cooking times. Most microwaves range from 600-1200 watts. Refer to your microwave manual to find the exact wattage. Then adjust roasting times up or down depending on if your microwave is on the lower or higher end of the wattage range.
Personal Taste Preferences
How long you roast tomatoes comes down to personal preference for the texture and flavor of roasted tomatoes. Some people prefer lightly roasted tomatoes that still hold their shape. Others like tomatoes roasted longer until they shrivel and caramelize. Take tomatoes out when they reach your desired level of roastedness.
Monitoring Progress
It’s important to monitor tomatoes as they roast and remove them when ready. Microwave cooking can quickly go from just right to burnt. Check tomatoes and stir or turn them halfway through roasting time. Then continue microwave for shorter intervals, checking every minute or so until tomatoes reach desired doneness. Adjust remaining cook times accordingly.
