Ingredients
  

Onion Boils
  • 4 large sweet onions (such as Vidalia) peeled and trimmed
  • 4 tablespoons unsalted butter divided
  • 4 cubes chicken bouillon
  • to taste fresh cracked black pepper
  • optional garlic powder
  • optional fresh thyme
  • optional shredded Parmesan cheese for topping

Equipment

  • Baking Dish
  • Aluminum Foil

Method
 

  1. Preheat oven to 375°F (190°C).
  2. Peel each onion and trim the top slightly so it sits flat. Cut a small well into the center of each onion.
  3. Place one tablespoon of butter and one bouillon cube into the center of each onion. Season with black pepper and any additional seasonings.
  4. Wrap each onion tightly in aluminum foil and place in a baking dish.
  5. Bake for 60–75 minutes, or until onions are fork-tender.
  6. Carefully unwrap (watch for steam), spoon the buttery broth over the onions, and serve warm. Optionally, top with Parmesan and broil for 2–3 minutes until golden.

Notes

For a vegetarian version, substitute vegetable bouillon for chicken bouillon. Onion Boils can be assembled ahead of time and refrigerated until ready to bake. They can also be cooked on a grill over medium heat for 45–60 minutes.
