Instructions

1.
Heat olive oil in a large skillet over medium-low heat. Add sliced onions and cook slowly, stirring occasionally, for about 25-30 minutes, or until deeply caramelized and golden brown. Add minced garlic during the last 5 minutes of cooking, stirring to prevent burning.
2.
Remove caramelized onions and garlic from heat and let cool slightly.
3.
In a food processor, combine the cooled caramelized onions and garlic, toasted pine nuts, Parmesan cheese, fresh thyme leaves, and optional balsamic vinegar.
4.
Pulse the mixture until a coarse paste forms. While the food processor is running, slowly drizzle in the remaining olive oil until the pesto reaches your desired consistency.
5.
Season with salt and black pepper to taste. Adjust seasoning as needed.
6.
Serve immediately over your favorite pasta, grilled vegetables, or as a spread.

Chef's Tips

To toast pine nuts, place them in a dry skillet over medium heat, stirring frequently until lightly golden and fragrant, about 3-5 minutes. Watch them carefully, as they burn easily.

For a smoother pesto, process the ingredients for a longer time, scraping down the sides of the food processor as needed.

Store leftover pesto in an airtight container in the refrigerator for up to 3 days. Add a thin layer of olive oil on top to prevent oxidation.
