How To Make an Onion Boil (Step-by-Step)

This method takes just 30 minutes and yields a cozy, healing dish you’ll want to make again and again.

1. Peel the onions. If they’re large, you can halve them. Small boiler onions can be left whole.
2. Bring your broth to a simmer. Add the olive oil, bay leaf, garlic powder, thyme, salt, and pepper to a medium saucepan with water or broth. Heat on medium until it starts to bubble.
3. Add the onions. Gently lower the onions into the pot. Reduce the heat to low so the onions cook slowly.
4. Simmer for 25–30 minutes. Let the onions soften completely. They should be tender and almost translucent.
5. Add optional acidity. Just before serving, stir in a splash of apple cider vinegar or lemon juice to brighten the dish.
6. Serve warm. Transfer to a bowl with a bit of the broth and garnish with fresh thyme or parsley, if desired.

Boiled Onions White vs. Red: What’s the Difference?

Both white and red onions can be used for boiling, but each brings something different to the table.

White onions become soft, sweet, and mild in flavor when boiled. They’re the classic choice for this dish.

Red onions, on the other hand, retain more bite and lend a rosy hue to the broth. Use them if you like a stronger onion taste and a splash of color in your presentation.

You could also try sweet yellow onions, but they’ll cook faster and have a softer texture.

Storage, Make-Ahead & Reheating Tips

Yes, you can definitely make onion boil ahead of time!

• Store cooled onions and broth in an airtight container in the fridge for up to 4–5 days
• Reheat gently in a saucepan over low heat. Add a splash of broth or water if needed
• Freeze portions in broth-safe containers for up to 3 months
• Add leftovers to grain bowls, pasta, or wraps

Use them to top a Croissant Breakfast Boat or as a warm addition to your next Freezer Breakfast Sandwich.
