Stuffed Onions I

Oven180°C (gas mark 4)
Time45–50 minutes

Ingredients

Directions

Prepare

  1. Heat the oven to 180°C (gas mark 4).

  2. Butter a small ovenproof dish.

  3. Put the vegetable stock and white wine in a medium saucepan and bring to a boil.

Cook the onion layers

  1. Trim 5 mm off the tops and bottoms of the onions, cut them in half lengthwise, and remove the brown papery skin.

  2. Gently scoop out most of the onion insides, retaining only the two or three outermost layers.

  3. Separate the outer layers from each other and place a few at a time in the simmering stock.

  4. Cook the onion layers for three to four minutes, until just tender, then drain and let cool slightly (reserve the stock for another use).

Stuff and bake

  1. Grate the tomatoes with a coarse cheese grater, discarding the skins.

  2. In a large bowl, combine the grated tomato pulp with breadcrumbs, feta, parsley, olive oil, garlic, spring onions, salt, and pepper.

  3. Fill each onion layer generously with the stuffing, then pull the sides together to form a fat cigar shape.

  4. Lay the stuffed onions seam-side down in the buttered dish and pour about 75 ml of the reserved stock over them, just enough to cover the bottom.

  5. Bake for 45–50 minutes, or until the onions are soft and lightly coloured and the stuffing is bubbling.

  6. If the onions dry completely before the end of cooking, add more stock.

  7. Drizzle with a little olive oil and serve warm.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

Onions
Form the edible shell that softens and turns sweet as it bakes.
Fresh white breadcrumbs
Absorb tomato moisture and give the stuffing a soft, binding body.
Feta
Adds salty, tangy richness that melts into the stuffing as it bakes.
Tomatoes
Supply moisture and acidity that keep the stuffing juicy.
Olive oil
Carries fat through the stuffing, adding richness and helping it brown.
Parsley
Adds fresh, herbaceous aroma that balances the rich feta.

The step that matters

Cook the onion layers only until just tender. Over-cooked layers turn mushy and tear when rolled, while under-cooked layers stay firm and bitter; a brief simmer softens the cell walls enough to fold without breaking.

Swap the clove

How well each one fits the dish's main ingredients (butter, white wine, onion, tomato, parsley, olive, garlic):
