Ingredients
- 3 large yellow onions, thinly sliced
- 1 large red onion, thinly sliced
- 1/2 cup unsalted butter
- 4 cups vegetable broth
- 4 cloves garlic, minced
- 4 sprigs fresh thyme
- 2 sprigs fresh rosemary
- 1 bay leaf
- 1.5 pounds small Yukon Gold potatoes, halved (optional, for a heartier dish)
- 1 teaspoon sea salt, or to taste
- 1/2 teaspoon black pepper, or to taste
- 1/4 cup fresh parsley, chopped, for garnish
Instructions
- In a large, heavy-bottomed pot or Dutch oven, melt the unsalted butter over medium heat. Add the thinly sliced yellow and red onions. Sauté gently, stirring occasionally, for 15-20 minutes until the onions are very soft and beginning to turn golden brown and caramelized.
- Add the minced garlic, fresh thyme sprigs, fresh rosemary sprigs, and bay leaf to the pot. Cook for another 2 minutes until the garlic is fragrant.
- Pour in the vegetable broth and add the halved Yukon Gold potatoes, if using. Bring the mixture to a gentle boil, then reduce the heat to low, cover the pot, and let it simmer for 20-25 minutes, or until the potatoes are fork-tender.
- Remove the bay leaf, thyme sprigs, and rosemary sprigs from the pot. Season the boil with sea salt and black pepper to taste. Adjust seasonings as needed.
- Ladle the comforting buttery onion boil into bowls. Garnish generously with fresh chopped parsley before serving hot.
Notes
For an even richer flavor, you can use chicken broth instead of vegetable broth. This dish pairs wonderfully with roasted chicken, seared beef, or as a standalone vegetarian meal with some crusty bread. Leftovers can be stored in an airtight container in the refrigerator for up to 3 days. The flavors deepen overnight!
