Ingredients Equipment Method Notes

Ingredients
  

  • 3 large sweet onions (like Vidalia) Peeled and sliced into 1/2-inch thick rounds
  • 1/2 cup unsalted butter Cubed
  • 2 beef bouillon cubes Crumbled
  • 1/2 tsp salt Or to taste
  • 1/4 tsp black pepper Freshly ground

Equipment

  • 1 9x13 inch Baking Dish
  • 1 Chef's Knife
  • 1 Aluminum foil

Method
 

  1. Preheat your oven to 400°F (200°C). Arrange the thick onion slices in a single layer in a 9x13 inch baking dish.
  2. Dot the onion slices evenly with the cubes of butter. Sprinkle the crumbled beef bouillon cubes over the top, followed by the salt and freshly ground black pepper.
  3. Cover the baking dish tightly with aluminum foil and bake for 30 minutes.
  4. Remove the foil and continue baking for an additional 15-20 minutes, until the onions are tender, golden brown, and the sauce is bubbly.
  5. Let rest for a few minutes before serving. Spoon the pan sauce over the onions when serving.

Notes

For best results, use a sweet onion variety like Vidalia or Walla Walla.
Ensure the onions are in a single layer to promote even cooking and browning.
Feel free to add a sprinkle of Parmesan or Gruyère cheese in the last 10 minutes of baking for a cheesy twist.
