Ingredients
- 4 large onions (yellow or white), approximately 1 kg (2.2 lbs) total
- 946 ml (4 cups) high-quality vegetable broth
- 30 ml (2 tablespoons) extra virgin olive oil
- 15 ml (1 tablespoon) garlic powder, finely ground
- 15 ml (1 tablespoon) onion powder, finely ground
- 5 ml (1 teaspoon) sweet paprika
- 5 ml (1 teaspoon) freshly ground black pepper
- 5 ml (1 teaspoon) sea salt, or to taste
- 15g (1/4 cup) fresh parsley or thyme, finely chopped, for garnish
- Optional: 2 ml (1/2 teaspoon) chili flakes, for added heat
Instructions
- Begin by meticulously preparing the onions. Carefully peel away the dry outer layers from each of the four large onions. Using a sharp knife, trim off both the top and root ends. For a more dramatic presentation, you can leave the onions whole, ensuring they are fully submerged later. Alternatively, for quicker cooking and easier consumption, slice them cleanly in half through the root end.
- In a generously sized, heavy-bottomed pot or Dutch oven, heat the 30 ml (2 tablespoons) of extra virgin olive oil over medium heat. Once shimmering, carefully add the prepared onions. Sauté them gently for 5 to 7 minutes, stirring occasionally, until they begin to soften and turn translucent around the edges, releasing their natural sweetness. This initial sautéing step is crucial for developing depth of flavor.
- Evenly sprinkle the 15 ml (1 tablespoon) of garlic powder, 15 ml (1 tablespoon) of onion powder, 5 ml (1 teaspoon) of paprika, 5 ml (1 teaspoon) of black pepper, and 5 ml (1 teaspoon) of sea salt over the sautéed onions. Stir diligently to ensure every surface of the onions is thoroughly coated with the aromatic spice blend. Allow them to cook for an additional minute, letting the spices bloom in the warm oil and infuse their fragrance.
- With care, pour the 946 ml (4 cups) of high-quality vegetable broth into the pot. Ensure that the onions are adequately submerged in the liquid. If the onions are not fully covered, you may add a splash more broth or water as needed, though the provided quantity should suffice for standard large onions.
- Increase the heat to high, bringing the vegetable broth to a vigorous, rolling boil. Maintain close observation during this stage to prevent boil-overs.
- As soon as the broth reaches a strong boil, immediately reduce the heat to its lowest setting. Cover the pot with a tight-fitting lid and allow the onions to simmer gently for approximately 30 minutes. This extended, slow simmer is where the magic happens, allowing the onions to become incredibly tender and absorb all the rich, savory flavors of the spiced broth.
- After the 30-minute simmering period, carefully remove the lid and check the tenderness of the onions. They should yield easily when pierced with a fork, indicating they are perfectly soft and thoroughly infused with flavor. If they require more time, simply replace the lid and continue simmering for an additional 5-10 minutes.
- Once the onions are perfectly tender, remove the pot from the heat. Allow the dish to rest for a few minutes, which helps to settle the flavors. Ladle the warm onion boil into individual serving bowls. Generously garnish with freshly chopped parsley or thyme. For those who enjoy a subtle kick, a sprinkle of chili flakes can be added. Serve immediately and enjoy the surprisingly satisfying depth of flavor.

Essential Success Tips
- Choose firm, fresh onions: The quality of your onions is paramount. Avoid any with soft spots or blemishes.
- Don't rush the sauté: Allowing the onions to gently soften and become translucent in olive oil builds a foundational layer of flavor.
- Bloom the spices: Cooking the spices briefly with the onions before adding broth enhances their aroma and taste profile.
- Low and slow simmer: The 30-minute simmer on low heat is critical for tenderizing the onions and allowing them to fully absorb the broth's flavors.
- Taste and adjust: Always taste the broth before serving and adjust salt or pepper as needed. A squeeze of lemon juice or a dash of vinegar can brighten the flavors.
Professional Cooking Secrets
- Caramelization bonus: For an even deeper, sweeter flavor, sauté the onions for an extra 10-15 minutes on medium-low heat before adding spices, allowing them to caramelize slightly. This adds a rich complexity.
- Umami boost: Incorporate a teaspoon of miso paste or a splash of soy sauce into the broth for an extra layer of umami. Dissolve it in a small amount of warm broth before adding to the pot.
- Herb infusion: For a more pronounced herbal note, tie a small bundle of fresh thyme or rosemary with kitchen twine and add it to the pot during the simmer, removing it before serving.

Notes
- Storage: Leftovers can be stored in an airtight container in the refrigerator for up to 3-4 days. Reheat gently on the stovetop or in the microwave.
- Variations: Feel free to add other vegetables like sliced carrots or celery along with the onions during the sautéing stage. A splash of dry white wine after sautéing the onions can also add sophistication.
- Serving suggestion: Serve as a light lunch, a comforting appetizer, or a healthy side dish to grilled meats or crusty bread.
Frequently Asked Questions
Can I use red onions instead?
While yellow or white onions are traditionally sweeter and milder when cooked down, red onions can be used for a slightly sharper, more robust flavor. Be aware they might tint the broth a reddish hue.
What if my onions aren't submerged in the broth?
If your onions aren't fully covered, you can add a little more vegetable broth or even water until they are adequately submerged. This ensures even cooking and flavor absorption.
Can I make this recipe spicier?
Absolutely! Besides adding chili flakes at the end, you can incorporate a pinch of cayenne pepper with the other spices, or add a sliced fresh chili (like a jalapeño or serrano) to the pot during simmering for more heat.
