These roasted onion cups melt like butter in your mouth. They have a subtle sweetness after they've roasted in the oven. With a little butter, parmesan and a drizzle of honey, you can't go wrong!
Preheat oven to 425℉. Lightly oil your muffin tray slots (skip this step if you have a silicone muffin tray).
Halve your onions through the center thick part (not the long way through the stems). Score the top of each onion half, halfway through. You don't want to score too deep or you will slice through the onion completely -see photo above.
Place onion halves cut side up into the muffin slots. Brush with olive oil, season with salt and pepper and place a small pat of butter on top of each onion. Roast for 20 minutes, remove from oven and baste with juice on each slot of the onion to the top of the onions. Roast for another 20 minutes. Top with grated parmesan and Italian herb blend and return to the oven for another 15 minutes or until golden on top.
