How to make Sweet and Sour Braised Red Onions

Step-by-step

1. Step 1

   Prepare the red onions evenly and pat dry if roasting, grilling or charring. Even shapes are more important than perfect shapes.

   Look for: The vegetables look evenly cut and ready to cook. Tip: Use a wide tray or pan so the vegetables have room to brown. Avoid: Uneven pieces cook at different speeds and look messy on the plate.

2. Step 2

   Toss with the fat and the flavour base: red wine vinegar, sugar, thyme, butter and stock. Season in layers so the vegetables taste good all the way through.

   Look for: The vegetables are lightly coated with no dry patches or puddles of oil. Tip: The seasoning should taste slightly bold before cooking because vegetables mellow as they cook. Avoid: Too much fat at the start can make the side greasy.

3. Step 3

   Cook using the braised glaze method until the vegetables are soft wedges with sticky edges. Keep the heat confident and avoid overcrowding.

   Look for: Edges colour while the centres become tender. Tip: For roasted sides, preheat the tray; for pan sides, let the pan get properly hot first. Avoid: Crowding traps steam and prevents restaurant-style browning.

4. Step 4

   Add the final herbs, citrus, vinegar, glaze, cheese, yoghurt or butter just before serving so the flavour stays bright.

   Look for: The side looks glossy, fresh and deliberate. Tip: A final sharp or salty note makes vegetables taste complete. Avoid: Adding delicate finishes too early can dull herbs, split dairy or flatten acidity.

5. Step 5

   Serve hot or warm with sausages, pork, steak, goat cheese, pies and tarts. Taste once more for salt, acidity and richness before plating.

   Look for: The finished side has contrast: tender vegetables, gloss, colour and a fresh final note. Tip: Finish with flaky salt, lemon, herbs or a little sauce only where it improves the balance. Avoid: Vegetables often taste flat if they are not checked after cooking.
