Method

01

Preheat the oven to 200 C or 400 F. Rub the halved bell peppers with olive oil and a pinch of salt, then place them cut-side up in a baking dish.

02

Roast the peppers in the preheated oven for 25 to 30 minutes until tender and slightly charred around the edges.

30mLook for: edges are wrinkled and slightly brownedFeel: flesh is tender when pierced with a fork
03

Meanwhile, heat olive oil in a skillet over medium-low heat. Add the sliced onions and a pinch of salt. Cook slowly, stirring occasionally, for 30 to 40 minutes until deep golden brown and sweet.

40mLook for: deep golden brown and jammy in textureFeel: very soft and reduced in volume
04

In a saucepan, combine the rinsed quinoa and vegetable broth. Bring to a boil, then reduce the heat to low, cover, and simmer for 15 minutes until the liquid is absorbed and the quinoa is tender.

15mLook for: quinoa grains have popped open showing their germ ringsFeel: tender with a slight bite
05

Remove the saucepan from heat and let it stand covered for 5 minutes. Fluff the quinoa with a fork, then fold in the lemon juice, lemon zest, chopped parsley, chopped mint, and olive oil.

06

Remove the roasted peppers from the oven and generously spoon the lemon-herb quinoa mixture into each pepper cavity.

07

Top each stuffed pepper with a generous mound of the caramelized onions. Serve warm.

Chef's Notes

  • For the deepest flavor in your caramelized onions, patience is key. Do not rush the process by turning up the heat.
  • Rinsing the quinoa before cooking is a crucial step to remove its natural saponin coating, which otherwise imparts an unpleasantly bitter taste.
  • Try adding a splash of balsamic vinegar to the onions in the last minute of cooking for extra depth and a touch of acidity.
  • To save time on a weeknight, you can caramelize the onions and cook the quinoa up to three days in advance.

Storage

Refrigerator: 4 daysStore in an airtight container. Keep the caramelized onions separate if possible to maintain texture.

Freezer: 2 monthsPeppers will be softer after freezing but retain good flavor.

Reheating: Reheat in the oven at 175 C (350 F) for 15 to 20 minutes until warmed through, or microwave for 2 to 3 minutes.
