Buttery Wine-Marinated Onions

At first glance you only need 35 minutes, apparently, to put together these delicious onions. However, at some point, you will have to forget them in the fridge for 12 hours while they’re marinating. This is when the magic happens. This is when they get so flavorful. Then, you transfer to the oven and let the butter soak them …


½ cup water
1 cup red wine
2 bay leaves
½ teaspoon black peppercorn
½ teaspoon dried thyme
1 tablespoon sugar
2 large onions, halved
1 ounce butter (cut into 4 cubes)
fresh rosemary


  1. Add the water, wine, bay leaves, peppercorn, thyme, and sugar to a bowl. Season with salt and pepper and mix.
  2. Add the halved onions, stir a little, cover the bowl with plastic foil and marinate for 12 hours.
  3. Transfer the marinated onions to a roomy baking dish with the cut halves up. Place a butter cube on top of each one and garnish with some rosemary.
  4. Bake for 30 minutes at 360⁰F/180⁰C.
