This Mediterranean-inspired dish of roasted stuffed red onions is a sophisticated addition to your recipe collection. By gently parboiling the onions and filling them with a savoury mixture of minced beef, fragrant dried mint, and fresh dill, you create a beautifully balanced meal that is both visually striking and deeply satisfying. The natural sweetness of the red onions caramelises in the oven, providing the perfect contrast to the zesty lemon and herbaceous rice filling.
As a high-protein main course or a substantial side dish, these stuffed onions are incredibly versatile. They can be prepared in advance and roasted just before serving, making them an excellent choice for a stress-free dinner party or a healthy weekend lunch. Serve them alongside a crisp green salad or some thick Greek yoghurt for a nutritious, homemade meal that feels truly special.

230g beef mince or lamb
2 dried bay leaves
2 teaspoons dried oregano
1 1/2 teaspoons dried mint

How to make Roasted Stuffed Red Onions
Back to contentsCook onions in a pot of boiling salted water until slightly softened, about 10 minutes. Using a slotted spoon, transfer to a large bowl; let cool slightly.
Working with 1 onion at a time, make a lengthwise slit from top to bottom with a paring knife, cutting through 2-3 layers of onion, depending on thickness of layers. Gently remove inside layers, allowing outer 2-3 layers to hold their shape. Finely chop enough of the inside layers to measure 240ml .
Heat 60ml oil in a large heavy skillet over medium heat. Add garlic and chopped onions; cook, stirring often, until soft, about 2 minutes. Add 1 tablespoon salt, beef, bay leaves, oregano, and mint; cook, breaking up meat with the back of a spoon, until meat is cooked through, 2-3 minutes. Stir in rice, 120ml wine, and 2 tablespoons lemon juice; cook, stirring often, until liquid is absorbed, about 3 minutes. Add dill and zest; mix well. Season filling with salt and pepper.
Preheat oven to 204°C. Spoon about 80g filling into each onion (it should be tightly packed). Place onions in a 13x9x2" baking dish, stuffed side up; drizzle with 60ml oil, 120ml wine, and 2 tablespoons lemon juice.
Roast onions until crispy on top and slightly browned, about 30 minutes. Serve hot or at room temperature.
