1. Classic Butter-Boiled Onions With Herbs That Melt in Your Mouth

If you’ve never had whole onions boiled in buttery, herby broth, prepare to fall in love. These are tender, sweet, and velvety—like the best part of French onion soup, but without the cheese coma. They’re a perfect side for roasted chicken or steak, but honestly, they’re a meal with crusty bread.

Ingredients:

• 8 small yellow onions, peeled and root trimmed (leave base intact to hold shape)
• 4 cups low-sodium chicken or vegetable broth
• 4 tablespoons unsalted butter
• 1 tablespoon olive oil
• 3 sprigs fresh thyme
• 1 bay leaf
• 1 teaspoon kosher salt
• 1/2 teaspoon black pepper
• 1 tablespoon lemon juice
• 2 tablespoons chopped parsley (for garnish)

Instructions:

1. Place the onions snugly in a wide saucepan. Add broth, butter, olive oil, thyme, bay leaf, salt, and pepper.
2. Bring to a gentle boil, then reduce to a simmer. Cover and cook 25–35 minutes, turning once, until the onions are fork-tender.
3. Remove the lid and simmer 5–10 minutes more to slightly reduce and thicken the buttery broth.
4. Stir in lemon juice. Adjust salt to taste. Remove thyme sprigs and bay leaf.

Ladle onions into shallow bowls, spoon the buttery broth over top, and finish with parsley. Variations: drizzle with balsamic, grate a little Parmesan, or add a splash of cream for a luxe finish.

How to Pick the Right Onions

For sweeter results, choose Vidalia or other sweet onions. Yellow onions are your all-purpose MVPs. Red onions add color and mild sharpness, especially in tomato-based broths or with citrus.

Pro Tips for Perfect Onion Boils

• Salt your liquid early. It seasons from the inside out.
• Keep the simmer gentle. A rolling boil can break onions apart.
• Finish with acid. Lemon juice, vinegar, or tomatoes brighten the sweetness.
• Balance fat and flavor. A pat of butter or drizzle of oil makes the broth feel luxurious.
