Ingredients

4 large yellow onions

4 tablespoons unsalted butter

1 cup beef broth

4 garlic cloves

1 tablespoon chopped fresh parsley

1 teaspoon salt

½ teaspoon freshly ground black pepper

2 sprigs fresh thyme (optional)

Instructions

1. Preheat oven to 375°F (190°C). Slice the tops off the onions and trim the root ends slightly so they sit flat. Peel the outer skin carefully without separating the layers. Hollow out a small well in the center of each onion without cutting through the bottom.

2. Place the onions upright in a snug baking dish. Season inside and outside with salt and black pepper. Add 1 tablespoon butter into the center of each onion and tuck in a garlic clove. Add thyme if using.

3. Pour beef broth into the baking dish until it reaches halfway up the sides of the onions.

4. Cover the dish tightly with foil and roast for 60 minutes, basting halfway through with the pan sauce.

5. Remove foil and continue roasting for 25–30 minutes, basting every 10 minutes, until the tops are golden brown and caramelized.

6. Check doneness by inserting a knife into the center; it should slide in easily.

7. Spoon pan sauce over each onion, sprinkle with fresh parsley, and serve hot.

Notes

Choose onions that are similar in size to ensure even cooking.

Do not skip covering during the first stage of roasting; this guarantees tender, fully softened layers.

For deeper flavor, let the onions rest 5–10 minutes before serving so the sauce thickens slightly.
