What type of onion works best?

Sweet onions like Vidalia, Walla Walla, or Maui provide a tender, mild flavor ideal for roasting.

How should onions be prepared before roasting?

Trim root ends and tops to sit flat, cut a shallow X on top, and season with butter, garlic, thyme, salt, and pepper before wrapping in foil.

Wrapping in foil traps steam and helps onions soften evenly while preserving moisture and infused flavors.

Roasting for about 1 hour 10 minutes ensures maximum tenderness; shorter times may leave onions firmer.

Fresh parsley adds color and brightness, while optional additions like balsamic vinegar or smoked paprika enhance depth.

Yes, it is naturally vegetarian and gluten-free; dairy-free versions can use vegan butter or olive oil.
