Ingredients
For the Onion Boil:
- 4 large onions (yellow or sweet onions work best)
- 6 cups vegetable broth (or chicken broth for extra depth of flavor)
- 2 tbsp butter
- 1 tbsp olive oil
- 2 cloves garlic, minced
- 1 tsp salt (or to taste)
- 1/2 tsp black pepper
- 1/2 tsp smoked paprika (optional, for a smoky flavor)
- 1/2 tsp dried thyme (or fresh if you have it)
- Fresh parsley for garnish (optional)
Instructions
1. Prepare the Onions: Peel the onions and cut off both ends. Slice them into thick rings (about 1-inch slices). You can also slice them into halves if you prefer larger pieces.
2. Heat the Pot: In a large pot, heat the butter and olive oil over medium heat. Once melted, add the minced garlic and sauté for about 1 minute, or until fragrant.
3. Add the Onions: Add the onion rings (or halves) to the pot and cook for about 5-7 minutes, stirring occasionally, until they begin to soften and lightly brown on the edges. This step helps to bring out the natural sweetness of the onions.
4. Add the Broth and Seasonings: Pour in the vegetable or chicken broth, then stir in the salt, black pepper, smoked paprika (if using), and thyme. Bring the mixture to a boil, then reduce the heat to low and let it simmer for about 20-25 minutes, or until the onions are soft and tender.
5. Simmer and Reduce: As the onions simmer, the broth will reduce and concentrate, creating a flavorful, aromatic base. If you prefer a thicker broth, let it cook for an additional 5-10 minutes, uncovered.
6. Serve and Garnish: Once the onions are tender and the flavors have melded together, remove from heat. Ladle the onion boil into bowls, garnish with fresh parsley if desired, and serve warm.

Make It Spicy: For a bit of heat, try adding a pinch of crushed red pepper flakes to the broth, or toss in some finely chopped chili peppers when sautéing the onions.
Vegan Version: This dish is easily made vegan by using vegetable broth and skipping the butter or substituting it with vegan butter or olive oil.
