Step 1

Peel your onion, leaving the root intact. If your onion sits level, you can leave it alone. If not, cut a thin slice off the root to create a flat bottom.

Step 2

Use a paring knife to cut a 1-inch deep cone into the top of the onion.

Step 3

Insert a vegetable, chicken, or beef bouillon cube into the hole.

Step 4

Fill the rest of the hole with butter, about 1-2 tablespoons. Season with salt and pepper.

Step 5

Place the onion in a microwave-safe container and cover with a lid.

Step 6

Microwave on high until tender, about 6-8 minutes. Serve warm. Drizzle with the remaining liquid for extra flavor.
