Prepare pizza dough according to recipe directions. Spread dough onto a baking pan lightly coated with olive oil. Make indentions into dough with finger tips and lightly drizzle crust with olive oil.
Drizzle olive oil into a large skillet over medium heat. Add onion slices and allow to cook until caramelized and tender, about 10 minutes. Watch onions closely so they do not overbrown. Arrange onions onto pizza dough and bake for 15-20 minutes until golden brown.
Remove from oven and immediately top with fresh thyme leaves that have been removed from the stem.
Sprinkle with salt and pepper, slice, and serve warm.
Notes
To reduce time, you can prepare pizza dough and store in an airtight container in the refrigerator for a few days until ready to use. Additionally, you could use prepared pizza dough purchased at your grocery store.
