Ingredients (Serves 4)
3 large red onions, peeled and sliced into ½-inch thick rounds
3 tbsp balsamic vinegar (aged preferred)
1 tbsp honey or maple syrup
2 tbsp olive oil
Salt and freshly ground black pepper, to taste
½ cup crumbled feta cheese
2 tbsp fresh parsley, finely chopped (or a mix of parsley and thyme)
Optional: a sprinkle of chili flakes or lemon zest for brightness
Instructions
1. Prep the Onions
Preheat oven to 400°F (200°C).
Line a baking sheet with parchment paper or foil.
Arrange onion slices in a single layer — try to keep the rings intact.
2. Make the Glaze
In a small bowl, whisk together balsamic vinegar, honey, and olive oil.
Season lightly with salt and pepper.
3. Roast & Glaze
Brush the onions generously with the balsamic mixture.
Roast for 20 minutes, flip gently, then brush again with remaining glaze.
Continue roasting for 15–20 minutes, until onions are tender and caramelized, with a glossy glaze.
4. Assemble
Remove from the oven and let cool slightly.
Transfer to a serving plate and sprinkle with crumbled feta and fresh herbs.
Optional: add a drizzle of extra balsamic glaze or olive oil for extra shine and depth.
Tips & Tricks
Keep onion rings intact: Use a sharp knife and cut straight through the root end.
Sweeter version: Add an extra drizzle of honey or use balsamic reduction instead of regular vinegar.
Vegan option: Substitute feta with vegan feta or toasted pine nuts.
Meal ideas:
Serve on top of grilled meats or polenta.
Add to salads, burgers, or bruschetta.
Mix into pasta with arugula and walnuts.
