FAQ

Can I use yellow onions instead of sweet onions?
Yes, though sweet onions give a milder, richer flavor.

What wine works best?
A dry white wine like Sauvignon Blanc or Pinot Grigio complements the cream well.

Can I prepare this ahead?
You can pre-roast the onions earlier in the day; add cream and bake before serving.

Can I add herbs?
Absolutely—thyme or rosemary adds a lovely aromatic touch.
