Onion Boil is a simple yet rich dish that brings out the natural sweetness and tenderness of onions. Simmered in broth with aromatic herbs and garlic, this dish is warm, comforting, and perfect as a side or soup base. The onions become incredibly soft, infused with flavor, and can be enjoyed on their own or paired with other ingredients for a hearty meal.

Ingredients:

For the Onion Boil:

  • 4 large onions (yellow or white), peeled and left whole
  • 4 cups vegetable or chicken broth
  • 2 cups water
  • 2 cloves garlic, smashed
  • 2 bay leaves
  • 1 tsp salt
  • ½ tsp black pepper
  • 1 tsp dried thyme or rosemary (optional)
  • 2 tbsp unsalted butter or olive oil (optional for richness)

For Garnish (Optional):

  • Fresh parsley, chopped
  • A squeeze of lemon juice
  • Grated Parmesan cheese

Preparation:

1: Prepare the Onions

  1. Peel the onions, keeping them whole to retain their shape.
  2. If desired, trim the root ends slightly so they sit flat in the pot.

2: Simmer the Onions

  1. In a large pot, combine the broth, water, garlic, bay leaves, salt, black pepper, and thyme or rosemary (if using).
  2. Bring to a gentle boil over medium heat.
  3. Carefully add the whole onions and reduce the heat to a low simmer.
  4. Cover and cook for 30–40 minutes, or until the onions are very tender and can be pierced easily with a fork.

3: Add Final Touches

  1. If using, stir in butter or olive oil for extra richness.
  2. Remove the bay leaves and discard them.

4: Serve & Garnish

  1. Place the whole onions in bowls and ladle some broth over them.
  2. Garnish with fresh parsley, a squeeze of lemon juice, or grated Parmesan cheese for extra flavor.
  3. Serve warm and enjoy!

Variations & Serving Ideas:

  • Rustic Onion Soup: Mash the onions slightly in the broth and serve with crusty bread.
  • French-Inspired Onion Boil: Add a splash of white wine to the broth for extra depth.
  • Caramelized Onion Finish: After boiling, pan-fry the onions with a little butter for added texture.

Cooking Notes:

  • Broth Choice: Use vegetable broth for a vegetarian-friendly version, or chicken broth for a richer taste.
  • Cooking Time: Simmering for 40 minutes makes the onions melt-in-your-mouth tender. For a firmer texture, reduce the cooking time to 25 minutes.
  • Storage: Store leftovers in an airtight container in the refrigerator for up to 3 days.

Serving Suggestions:

  • Serve alongside grilled meats, roasted vegetables, or mashed potatoes.
  • Use the leftover broth as a base for soups or stews.

Tips:

  1. For Extra Flavor: Add a splash of balsamic vinegar to the broth before serving.
