  • 3 tablespoons extra virgin olive oil Can substitute with avocado oil
  • 2 tablespoons balsamic vinegar Substitute with red wine vinegar plus a pinch of sugar
  • 1 tablespoon honey Substitute with maple syrup for a vegan option

  • 2 cloves garlic, minced Substitute with 1/2 teaspoon garlic powder in a pinch

Method
 

Preparation
  1. Preheat the oven to 400°F (200°C) and line a baking dish with parchment.
  2. In a bowl, whisk together olive oil, balsamic vinegar, honey, Dijon, minced garlic, smoked paprika, salt, and pepper.
  3. Taste and adjust the marinade, ensuring a balance of sweet and tangy.
  4. Place onion halves cut-side up in the baking dish. Spoon the marinade over each onion, allowing it to seep between layers.
Cooking
  1. Cover the baking dish loosely with foil and roast for 25 minutes.
  2. Remove the foil and roast for another 10–20 minutes until edges are golden and the centers are tender and slightly caramelized, baste once halfway through.
Finishing Touch
  1. Remove from oven, sprinkle with chopped parsley and nutritional yeast if desired.
  2. Let rest for 5 minutes before serving.

Notes

For added smoky flavor, include a teaspoon of liquid smoke in the marinade. After roasting, toss onions with Greek yogurt and dill for a creamy twist. Store leftovers in an airtight container for up to 4 days, or freeze for 2 months.
