This is a tasty start to a meal, either as a first course or an appetizer. It also stands out in a Sunday brunch. The combination of the cauliflower, the cheeses, and the sweetness of the caramelized onions is irresistible. Read more . Use the best quality Gruyère you can and grate your Parmesan immediately before using. The mascarpone adds to the creaminess of the tart. Ingredients:
1 small head of cauliflower (about 1 pound), cored, cut into 1-inch florets |
3 tablespoons olive oil |
1 tablespoon extra virgin olive oil |
pie crust |
1 large onion, halved lengthwise, thinly sliced |
1 tablespoon dijon mustard |
2 large eggs |
8 ounces mascarpone cheese |
1/2 cup whipping cream |
1/4 teaspoon ground white pepper |
pinch of ground nutmeg |
1 cup grated gruyère cheese |
3/4 cup grated parmesan cheese |
Directions:
1. Position rack in center of oven; preheat to 425°F. Toss cauliflower with 1 tablespoon olive oil in large bowl. Spread on large rimmed baking sheet, covered with a sheet of parchment paper or a Silpat, spacing apart. Sprinkle with salt and pepper. Roast 15 minutes; turn florets over.
2. Continue roasting until tender, about 25 minutes longer. Cool cauliflower, then thinly slice. Drizzle with a bit more olive oil.
3. Reduce oven temperature to 350°F.
4. Prepare a pie crust and press the crust onto bottom and up the sides of 9-inch-diameter tart pan with removable bottom. Line the crust with foil or parchment paper; fill with pie weights, beans, or pennies.
5. Bake crust 20 minutes. Remove foil and pie weights; bake until crust is golden, about 5 minutes, pressing crust with back of fork if bubbles form. Cool crust. Keep the oven at 350.
6. Heat 11/2 tablespoons olive oil in heavy large skillet over medium heat. Add onion; sprinkle with salt and pepper. Cook until onion is deep golden brown, stirring occasionally, about 40 minutes. It's important that (1) the onions don't burn, and (2) they caramelize completely. Cool slightly.
7. Brush bottom and sides of crust with Dijon mustard. Spread onion in crust. Arrange cauliflower evenly over. Set tart on rimmed baking sheet. Whisk eggs and next 4 ingredients in medium bowl. Stir in Gruyère. Pour mixture over filling in tart pan; sprinkle with Parmesan.
8. Bake until tart is golden and center is set, about 40 minutes.
9. Transfer to rack; cool 15 minutes before serving.
10. This tart sets up extremely well and can be kept covered and refrigerated overnight. Warm slightly before serving.
11. I've found that the recipe works equally well if you decide to make smaller, individual tarts. In this case, the final cooking time might be a bit shorter. Just keep an eye on your tarts while they're baking.
