Ingredients

• 4 large sweet onions (peeled, tops trimmed, but root intact)
• 4 tablespoons unsalted butter
• 4 cups vegetable broth
• Salt & pepper (to taste)
• Fresh herbs for garnish (thyme, rosemary, or parsley)

Instructions

1. Prepare the Onions

• Peel 4 large onions and trim the tops, but keep the root intact to hold them together.
• Place the onions in a large pot and pour in 4 cups of vegetable broth.
• Season with salt and pepper to taste.

2. Boil the Onions

• Bring the broth to a boil over medium-high heat.
• Once boiling, reduce the heat to low, cover the pot, and let the onions simmer for 30-40 minutes until fork-tender.

3. Add Butter

• Remove the onions from the pot and place them on a serving platter.
• Top each onion with a tablespoon of butter, letting it melt over the warm onions for extra richness.

4. Garnish & Serve

• Sprinkle with fresh herbs (thyme, rosemary, or parsley) for added flavor.
• Serve warm as a delicious side dish alongside grilled meats, roasted vegetables, or crusty bread.

Notes

• For extra flavor, add a bay leaf or a splash of white wine to the broth while simmering.
• Make it dairy-free by using plant-based butter or a drizzle of olive oil.
• Use different onions – Sweet onions work best, but you can also try yellow, red, or pearl onions for variety.

Helpful Tips for the Best Onion Boil with Herb Dressing

1. Use Sweet Onions for the Best Flavor – Varieties like Vidalia, Walla Walla, or Maui onions provide natural sweetness that enhances the dish.
2. Keep the Root Intact – This prevents the onions from falling apart while boiling. Trim only the top, not the base.
3. Don’t Overcook – Check the onions at 30 minutes by piercing with a fork. They should be tender but still hold their shape.
4. Enhance the Broth for More Flavor – Add a bay leaf, garlic cloves, or a splash of white wine for extra depth.
5. Save the Broth for Future Use – The onion-infused broth is full of flavor—use it for soups, stews, or sauces instead of discarding it.
6. For an Extra Buttery Finish – After topping with butter, cover with foil for a few minutes to let the butter soak in before serving.
7. Garnish Just Before Serving – Fresh herbs lose flavor when overheated, so add parsley, rosemary, or thyme right before plating.
8. Add a Tangy Kick – A drizzle of balsamic glaze or splash of lemon juice can balance the richness.
9. Want a Crispy Twist? – After boiling, broil the onions for 3-5 minutes until lightly golden for a slightly caramelized top.
10. Make It a Meal – Serve over mashed potatoes, risotto, or crusty bread to turn this side into a main dish.

Conservation and Storage

Refrigeration (Up to 3 Days)

• Store leftovers in an airtight container with a bit of the cooking broth to keep them moist.
• Reheat on the stovetop over low heat or in the microwave with a little broth to prevent drying.

Freezing (Up to 2 Months)

• Let onions cool completely, then freeze in a sealed container with broth.
• Thaw overnight in the fridge and reheat gently on the stove.

Substitutions and Variations

• Add Garlic: Toss in whole garlic cloves with the onions for extra depth.
• Cheese Topping: Sprinkle with Parmesan or crumbled feta for a cheesy upgrade.
• Spicy Version: Add red pepper flakes or a pinch of cayenne for heat.
• Use Chicken Broth: Swap vegetable broth for chicken broth if not vegetarian.
