A Vermont Childhood Built on Simplicity
Where My Love of Boiled Onions Began
I grew up in a chilly Vermont town, and when winter rolled in, the kitchen became our safe zone. While my father was outside managing the woodpile, my mother was simmering something—usually onions. She didn’t call it “onion boil.” She just called it “dinner.”
Sometimes she added potatoes. Other times, it was just a pot of water, sliced onions, and salt. We’d pour it into bowls and eat it with crusty bread. It wasn’t fancy, but it was magic. Those bowls didn’t just fill our stomachs—they settled us.
That early memory never left me. Even now, decades later in Asheville, that same aroma on my stove makes me feel grounded.
My Go-To Use for Onion Boil in Today’s Kitchen
These days, I use boiled onions in all kinds of meals. They bring a soft, mellow sweetness that balances sharp flavors and gives depth to light dishes. One of my favorite combos is a big spoonful of them next to this dense bean salad recipe. It’s fresh and bold, while the onions add warmth and softness.
You can also sip the broth on its own when you’re feeling run-down. Add lemon or fresh ginger to make it brighter, or keep it plain when you just want something quiet.
If you’ve never tried a simple onion boil before, you might be surprised by how satisfying it can be. Sometimes, the best dishes come from doing less—and letting the ingredients do all the talking.

Step-by-Step Instructions
This onion boil recipe is simple, low-maintenance, and only takes about 30 minutes. Here’s how I make it:

You can leave the root on to help them hold their shape, or slice them into thick wedges if you prefer smaller bites. - Add all ingredients to a medium pot.
Pour in the water, add the onions, salt, and any optional garlic or herbs. - Bring to a gentle boil.
Set the pot over medium-high heat and bring the mixture to a boil. Once bubbling, reduce the heat. - Simmer for 25–30 minutes.
Let the onions cook until they’re fork-tender and the broth is lightly golden. Keep the lid slightly ajar to concentrate the flavor. - Taste and adjust.
Add more salt if needed. You can also stir in a splash of vinegar or lemon juice for brightness. - Serve warm.
Ladle the broth into a mug or bowl and enjoy it as-is, or serve the boiled onions as a side dish.
Boiled onions store beautifully—just keep them in an airtight container with some broth. You can reheat and sip as needed, or use them as the base for soups or casseroles. I’ve even used them in a cozy recipe like this chicken broccoli potato casserole—they add an incredible depth of flavor without overpowering the dish.

A warm onion boil isn’t just cozy—it’s functional. If you’ve ever sipped the broth from a freshly boiled onion, you know it can be surprisingly soothing.

Serving Suggestions for Your Onion Boil
A fresh pot of onion boil can be as versatile as you need it to be. You can serve the boiled onions on their own, spooned into a bowl with warm broth and a sprinkle of sea salt, or pair them with heartier meals for added comfort and depth.
Here are a few of my favorite ways to enjoy them:
- As a sipping broth: Ladle the hot broth into a mug and sip slowly—ideal for chilly evenings or days when you’re feeling under the weather. Add a twist of lemon for brightness or ginger for warmth.
- With mashed potatoes or grains: Spoon the soft, boiled onions over creamy mashed potatoes, farro, or quinoa. The natural sweetness of the onions melts into the starch for a deeply satisfying dish.
- Next to roasted meats or veggies: A bowl of onion boil makes an earthy, gentle side dish next to grilled chicken, baked tofu, or even a colorful plate of roasted root vegetables.
- Blended into soup: Take your leftover onions and broth, blend them until smooth, and serve as a light, velvety soup. A drizzle of olive oil and some crusty bread complete the picture.
For a full cozy dinner, I love serving onion boil with this chicken taco casserole with rice. The mellow onions balance the spicy richness of the casserole perfectly.
Whether you eat it solo or build it into a full meal, this is the kind of dish that doesn’t shout—but it never goes unnoticed.
