Ingredients
- 4 medium yellow or white onions
- 30 grams (2 tablespoons) unsalted butter
- 60 milliliters (1/4 cup) soy sauce (or tamari for gluten-free)
- 120 milliliters (1/2 cup) water or vegetable broth
- 5 grams (1 teaspoon) smoked paprika
- 2.5 grams (1/2 teaspoon) garlic powder
- 1.25 grams (1/4 teaspoon) red chili flakes (adjust to taste)
- 1.25 grams (1/4 teaspoon) dried oregano
- Pinch of black pepper
- Fresh parsley or chives for garnish (optional)
Instructions
- Carefully peel the outer layers from each onion, then trim both the root and stem ends. It's important to leave just enough of the root intact to help hold the onion together during cooking. Using a sharp knife, make a small cross incision about 1.25 centimeters (1/2 inch) deep into the top of each onion; this allows the flavors to penetrate deep inside the onion as it cooks.
- In a medium-sized pot, bring a generous amount of lightly salted water to a rolling boil. Gently place the prepared onions into the boiling water and parboil them for 10-12 minutes, or until they have softened slightly but still maintain their structural integrity and are firm to the touch. This initial boil helps to mellow their raw bite and prepares them for absorbing the rich sauce. Drain the onions thoroughly and set aside.
- Select a deep skillet or a small Dutch oven large enough to comfortably hold all four onions in a single layer. Melt the 30 grams (2 tablespoons) of unsalted butter over medium heat. Once the butter is shimmering, add the parboiled onions and sauté them gently for 3-5 minutes, carefully turning them occasionally, until each side develops a beautiful light golden hue. This step adds a layer of caramelized flavor.
- Pour in the 60 milliliters (1/4 cup) of soy sauce (or tamari) and the 120 milliliters (1/2 cup) of water or vegetable broth. Next, stir in the 5 grams (1 teaspoon) of smoked paprika, 2.5 grams (1/2 teaspoon) of garlic powder, 1.25 grams (1/4 teaspoon) of red chili flakes (adjusting to your preferred level of heat), and 1.25 grams (1/4 teaspoon) of dried oregano. Bring the liquid to a gentle simmer, ensuring all the spices are well incorporated.
- Once simmering, reduce the heat to low, cover the skillet or Dutch oven, and let the onions gently simmer for 15-20 minutes. The goal is for the onions to become exquisitely fork-tender, and for the flavorful liquid to reduce into a rich, glossy, and slightly thickened sauce that clings beautifully to the onions. Periodically, lift the lid and spoon the simmering sauce over the onions to ensure they are evenly coated and absorb all the delicious flavors.
- Carefully remove the pot from the heat. Finish the dish with a pinch of freshly ground black pepper to enhance the overall flavor profile. Serve the onions immediately, making sure to generously spoon the luxurious, reduced sauce over each one. For an added touch of freshness and visual appeal, garnish with freshly chopped parsley or chives, if desired.

Essential Success Tips
- Choose firm, fresh onions without soft spots for the best texture and flavor. The variety (yellow or white) will slightly alter sweetness.
- Do not over-parboil the onions; they should still have some resistance when pierced. This ensures they don't turn mushy during the simmering stage.
- Ensuring the root end is slightly intact is crucial to keep the onion from falling apart during the cooking process, maintaining its individual shape.
- Periodically basting the onions with the simmering sauce helps infuse maximum flavor into every layer and ensures even cooking.
- Taste and adjust the seasoning, especially the red chili flakes and black pepper, just before serving to perfectly balance the flavors to your preference.
Professional Cooking Secrets
- For an even richer umami depth and a hint of tang, consider adding a tiny splash of balsamic vinegar or a pinch of mushroom powder to the sauce towards the end of simmering.
- To achieve a beautifully glossy and slightly thicker sauce without any added starch, remove the onions once tender, then reduce the sauce over medium-high heat for an additional 2-3 minutes until it coats the back of a spoon.
- Experiment with different onion varieties for varied flavor profiles; red onions will offer a sweeter, slightly tangier profile, while sweet onions like Walla Walla or Vidalia will be even milder and more delicate.

Notes
- Storage: Leftovers can be stored in an airtight container in the refrigerator for up to 3 days. Reheat gently on the stovetop over low heat, adding a splash of water or broth if the sauce has become too thick.
- Variations: For an added layer of complexity, stir in a teaspoon of white miso paste with the soy sauce, or a pinch of dried thyme alongside the oregano.
- Serving Suggestion: This dish pairs wonderfully with roasted chicken, grilled fish, or as a hearty vegetarian main course alongside a side of fluffy rice or crusty bread to sop up the exquisite sauce.
Frequently Asked Questions
Can I make this dish ahead of time?
Yes, the onions can be parboiled and even simmered in the sauce a day in advance. Gently reheat on the stovetop over low heat, adding a splash of broth or water if the sauce has become too thick. The flavors often deepen overnight.
What kind of onions are best for this recipe?
Yellow or white onions work wonderfully, offering a balanced sweetness and pungency that holds up well to simmering. Sweet onions like Vidalia or Walla Walla can also be used for an even milder and sweeter flavor profile.
Is this recipe vegan and gluten-free?
The recipe is naturally vegan if you use vegetable broth instead of water and ensure your butter substitute (if any) is plant-based. To make it gluten-free, ensure you use tamari instead of regular soy sauce, as tamari is typically gluten-free.
