Viral Onion Boil Recipe – How To Make Boiled Onions Like TikTok

Ingredients

• 1 large (15 oz) sweet onion, peeled and trimmed at both ends
• 1 tablespoon vegan butter
• 1 tablespoon extra virgin olive oil
• 1 teaspoon Cajun seasoning
• ¼ teaspoon salt (plus extra for seasoning each layer while serving)
• Optional: ¼ teaspoon garlic powder, ¼ teaspoon Old Bay seasoning
• Optional garnish: finely chopped parsley

Instructions

1. Preheat your oven to 375°F (190°C).
2. Prepare the onion by scooping out a small portion from the top center using a melon baller, about a third of the way down, creating a little cavity.
3. Place the onion on a sheet of aluminum foil. Add the butter into the cavity. Mix the olive oil with the Cajun seasoning (and any optional spices) and pour the mixture over the butter, letting it trickle down the sides of the onion. Sprinkle with salt and any extra seasonings you like.
4. Wrap the onion tightly in the foil and place it in a small baking dish or cast iron skillet to catch any escaping juices.
5. Roast on the middle rack for about 1 hour. After this, carefully open the foil and check the onion. It should be tender throughout and the center should jiggle slightly. The edges may have started to caramelize. If it’s not fully done, reseal the foil and roast for an additional 10 minutes, then check again.
6. For extra caramelization (optional), switch the oven to broil. Open the foil, drizzle a bit more melted butter or olive oil, and sprinkle a pinch of salt on top. Broil for 5–10 minutes, keeping a close eye to prevent burning. This will give the top a golden, caramelized finish.
7. Serve by peeling away the outer layer and enjoying each soft layer underneath. Pour all the flavorful juices from the foil over the onion and add extra salt if desired. This pairs wonderfully with rice, roasted chickpeas, or other vegetables like crispy Brussels sprouts. Enjoy hot!

Notes

Store any leftovers in an airtight container in the fridge once the onion has cooled to room temperature.
