Servings: 8 Servings
Calories: 184kcal
Ingredients
- 3 large red onions sliced very thin
- 3 large sweet white onions sliced very thin
- 8 tablespoons unsalted butter refined coconut oil, or ghee
- 1 tablespoon kosher or fine sea salt or more to taste
- ⅔ cup dry red cooking wine or sherry
- 4 tablespoons Worcestershire sauce
- 1 bay leaf
- 1 teaspoon dried thyme or 1 tablespoon fresh
- 7 cups gluten-free low-sodium beef stock
Instructions
- Put the onions in a slow cooker with the butter and salt. Cook on high for 6 hours, stirring occasionally.
- Once the onions are caramelized, add the remaining ingredients to the slow cooker and cook on high for another 2-4 hours.
- Alternatively, if you’re strapped for time, put the caramelized onions in a large soup pot and add the remaining ingredients. Bring to a boil, then simmer for 1 hour.
- Note: If you’re not dairy-free, pour some soup in an oven-safe soup crock and cover with 1-2 slices of provolone cheese. Place under the broiler for a couple minutes until the cheese is bubbly and slightly brown on the edges.
