Ingredients
Scale
Ingredients
- 1 large (15 ounce) sweet onion, peeled and ends trimmed off
- 1 tablespoon vegan butter
- 1 tablespoon extra virgin olive oil
- 1 teaspoon Cajun seasoning
- ¼ teaspoon salt (plus more to taste when serving each layer)
- Optional additional seasonings: ¼ teaspoon garlic powder, ¼ teaspoon Old Bay seasoning
- Optional garnish: finely diced parsley leaves
Instructions
- Preheat the oven: Preheat your oven to 375 degrees F to prepare it for roasting the onion.
- Prepare and season the onion: Use a small melon baller to scoop out the top center portion of the onion about one-third of the way down to create a well. Place the onion on a sheet of aluminum foil. Add the vegan butter into the well, then mix Cajun seasoning, olive oil, and salt (plus any optional seasonings) and pour this mixture over the butter in the well, allowing the oil and seasonings to drip down the sides of the onion.
- Wrap and bake: Wrap the entire onion tightly in the aluminum foil and place it in a small baking dish or a cast iron skillet to catch any excess oil. Roast on the center rack of the oven for 1 hour until the onion is fork tender and slightly caramelized.
- Check and extend cooking if needed: Remove from the oven, open the foil to check doneness; the onion should jiggle and be fully tender. If necessary, reseal the foil and roast for an additional 10 minutes, then recheck.
- Optional broiling for caramelization: For a golden brown, caramelized exterior, open the foil, drizzle more melted vegan butter or olive oil, add a pinch of salt, then broil the onion for 5-10 minutes watching carefully to prevent burning.
- Serve: Peel away the outer layer of the onion and enjoy the tender layers inside, seasoning with extra salt if desired. Pour the flavorful juices collected in the foil over the onion. This dish pairs wonderfully with rice, crispy chickpeas, or roasted vegetables like Brussels sprouts.
Notes
- Store leftovers in an airtight container in the refrigerator after the onion has completely cooled to room temperature.
- Adjust seasoning to taste, especially when serving individual layers.
- Optional garnishes like finely diced parsley can add freshness.
- Broiling step is optional but adds a delicious caramelized texture.
