Description
This viral TikTok onion boil transforms a humble sweet onion into a buttery, caramelized masterpiece. It’s simple, comforting, and absolutely addictive.
Ingredients
Scale
- 1 large sweet onion (Vidalia, Walla Walla, or Maui – about 15 oz)
- 2 tablespoons vegan butter (or regular butter)
- 1 tablespoon extra virgin olive oil
- 1 teaspoon cajun seasoning
- 1/4 teaspoon garlic powder (optional)
- 1/4 teaspoon Old Bay seasoning (optional)
- Salt, to taste
- Aluminum foil
Instructions
- Preheat your oven to 375°F (190°C).
- Peel the onion and trim both ends so it sits flat.
- Use a melon baller or spoon to scoop out a well in the top center of the onion, about one-third deep.
- Place the onion on a square of aluminum foil.
- Add the butter into the well.
- In a small bowl, mix cajun seasoning, garlic powder, Old Bay (if using), and olive oil.
- Pour the oil mixture over the onion and let it cascade down the sides.
- Sprinkle salt generously over the top and sides.
- Wrap the onion tightly in the foil to seal it completely.
- Place the wrapped onion in a small oven-safe dish or cast iron skillet.
- Roast in the oven for 60 minutes.
- Carefully unwrap the foil (watch for steam) and check tenderness with a fork — it should glide through easily.
- If needed, rewrap and roast for another 10 minutes.
- Optional: Drizzle with more butter, sprinkle salt, and broil uncovered for 5–7 minutes until golden and crispy on top.
Notes
Use sweet onions for best flavor. Don’t skip the salt—it brings out the onion’s natural sweetness. Watch closely during broiling to avoid burning.
