Have you ever heard of the Onion Boil? This simple yet incredibly flavorful dish has taken the internet by storm, and for good reason! Roasted to perfection with a luscious blend of vegan butter, olive oil, and Cajun spices, this tender, melt-in-your-mouth onion is the perfect balance of smoky, buttery, and slightly sweet flavors. Whether you’re looking for a delicious side dish or a unique addition to your plant-based meals, the Onion Boil is a must-try!
Ingredients and Preparation Steps
What You’ll Need:
- 1 large sweet onion, peeled and ends trimmed
- 1 tablespoon vegan butter
- 1 tablespoon extra virgin olive oil
- 1 teaspoon Cajun seasoning
- ¼ teaspoon salt (plus more to taste)
Step 1: Prepare Your Onion
Preheat your oven to 375°F (190°C). Use a melon baller or small spoon to scoop out the top center of the onion, creating a well about a third of the way down. This will allow the flavors to infuse beautifully.
Step 2: Add Seasoning and Wrap
Place the onion on a sheet of aluminum foil. Add the vegan butter into the well, then mix the Cajun seasoning with the olive oil and pour it over the butter, letting it seep into the onion. Sprinkle with salt for extra flavor.
Step 3: Roast to Perfection
Wrap the onion tightly in foil and place it in a baking dish to catch any juices. Roast for 1 hour until fork-tender and slightly caramelized.
Step 4: Broil for Extra Caramelization
For extra depth of flavor, open the foil, drizzle with a bit more olive oil, and broil for 5-10 minutes until golden brown. Serve hot, peeling away the outer layer to reveal the tender, flavorful layers beneath. Don’t forget to pour the remaining juices from the foil over the onion for maximum taste!

Frequently Asked Questions About Onion Boil

Is there a way to make this recipe without foil?
Absolutely! You can place the onion in a covered oven-safe dish or wrap it in parchment paper before baking. This will still allow the onion to steam while roasting.
