Ingredients
- 3 tablespoons grass-fed butter, clarified is preferred
- 4 Vidalia onions
- 2 cups (500 ml) red wine
- 2 cups (500 ml) water, + more for deglazing pan
- ½ cup (125 ml) sherry
- 3 cups (750 ml) beef broth
- 4 sprigs fresh thyme
- 1 bay leaf
How to Make It
- Preheat oven to 400°F (205°C).
- Use some of the butter to grease the bottom of a large Dutch oven, and place remainder of butter and all onions into the Dutch oven. Cover and cook in oven for 1 hour.
- Remove the pot from the oven, stir the onions and butter scraping the sides and bottom, and place back into the oven with lid slightly ajar for another 60–90 minutes.
- Meanwhile, in a small saucepan, heat wine over medium heat, and reduce down until it’s about ¼ cup in total volume. Remove from heat.
- Remove the pot of onions from the oven, and place uncovered on stove on medium-high heat. Scrape the sides and bottom of pan frequently, until the liquid mostly evaporates and the onions are browned.
- Continue to cook until the bottom of the pan has a brown crust, about 6–8 minutes.
- Stir in about ¼ cup (60 ml) of the water, being sure to scrape up the crust on the bottom of the pan.
- Cook until the water has evaporated and you have another dark crust. Repeat this addition of water until the onions are dark brown.
- Mix in the wine and sherry and cook, stirring frequently, until the liquids evaporate.
- Mix in the beef broth, 2 cups (500 ml) water, thyme, and bay leaf, scraping up any bits of fond that may be on the bottom and sides of pan.
- Bring the liquid up to a boil, then reduce heat to a low simmer, cover, and allow to simmer for about 30 minutes. Remove thyme and bay leaf, and season as you prefer with salt and pepper.
