Romesco Sauce
Instructions
Roasted Parsnips
- Preheat oven to 425°F.
- Cut parsnips and bell pepper (remove seeds) in half and place on a parchment-lined sheet pan. Add onion wedges.
- Drizzle lightly or brush with olive oil, getting the undersides of the parsnips as well. Sprinkle with salt and pepper.
- Roast until fork tender, 30-35 minutes. Check at 20 minutes, rotate pan, and continue cooking until very tender and deeply golden.
Romesco Sauce
- Place roasted bell pepper and onion in a food processor.
- Add remaining romesco ingredients and pulse until combined into a paste.
To Serve
- Spoon the romesco sauce onto a platter and smear it creatively with the back of a spoon.
- Arrange the parsnips on top of the sauce.
- Sprinkle with chopped parsley and crushed hazelnuts. Serve immediately.
Notes
- For a deeper, more caramelized flavor, ensure the parsnips are deeply golden—avoid pale parsnips.
- Hazelnuts and almonds both work well in the romesco sauce; choose based on preference.
- The romesco sauce can be made ahead and stored in the refrigerator.
