Eggplant is a versatile vegetable that can be prepared in many different ways. However, traditional cooking methods like roasting, grilling or frying can be time consuming and require a good amount of oil.

Cooking eggplant in the microwave is a quick and healthy alternative that takes just a few minutes. The microwave helps soften and cook the eggplant without needing to add any extra fat.

Read on to learn everything you need to know about cooking eggplant in the microwave. We’ll cover microwave wattage, cook times, instructions, tips and delicious recipe ideas to make with your cooked eggplant.

Here’s a quick answer: To cook eggplant in the microwave, first cut it lengthwise into 1/2 inch thick halves and brush with olive oil. Place the halves cut-side up in a microwave-safe dish, cover, and microwave for 7-8 minutes for one medium eggplant or 8-9 minutes for two medium eggplants. Check for doneness and microwave for 1-2 more minutes if needed. Eggplant is done when very tender.

Benefits of Cooking Eggplant in the Microwave

Here are some of the main benefits of using the microwave to cook eggplant:

  • It’s fast – Cooking eggplant in the microwave takes only 5-10 minutes compared to roasting which can take 30-60 minutes.
  • Uses less oil – You only need to brush a small amount of oil on the eggplant to help it cook evenly. Roasting or frying eggplant requires more oil.
  • Retains nutrients – Microwaving is a moist heat method of cooking so fewer nutrients are lost compared to dry heat methods.
  • Has great texture – Eggplant comes out tender on the inside but still holds its shape well.
  • Easy cleanup – Microwaving eggplant is less messy than roasting or frying. Just place it on a dish, cover and cook.

How to Choose Your Eggplant

When selecting eggplant for cooking, you’ll want to pick ones that are fresh, firm, and free of blemishes. This will ensure the best flavor and texture.

Look for eggplants that feel heavy for their size and have smooth, shiny, taut skin. The skin should have a bright, rich color whether it’s the classic dark purple, striped purple and white, or green. Avoid eggplants with soft wrinkled skin or brown/yellow discoloration as this indicates overripe produce.

Press gently on the eggplant. It should feel firm with no indentation. Soft squishy spots mean the interior flesh is becoming mushy and spoiled. Also inspect the stem and cap. They should be bright green and not dried out. Pass on eggplants with cuts, bruises or mold.

Smaller eggplants around 6-8 inches long tend to be more tender and have fewer seeds. The long thin Asian varieties and oval shaped Italian globes work well for most cooking methods. Larger, more rounded eggplants can be used if you’re planning to scoop out and cook the flesh. Try different types to see which you prefer.

For peak freshness, use eggplant within 2-3 days of purchasing. Choose firm, unblemished eggplants and you’ll be ready to enjoy their unique flavor and texture.

Microwave Wattage for Cooking Eggplant

Most microwave ovens range from 600-1200 watts. Higher wattage microwaves will cook food faster than lower wattage models. Refer to your microwave manual to find the wattage.

For best results, we recommend using a 700-watt microwave oven. Adjust cook times up or down if your microwave has higher or lower wattage.
