ingredients for preparation :

2 large carrots, peeled and cut on the diagonal into 1/2-inch thick slices
1/2 pound red onions, each halved and cut into 6 or 8 wedges through the root end
1 fennel bulb, halved lengthwise and cut into 1/2-inch wide wedges through the core
2 zucchini, ends trimmed, halved lengthwise, and cut on the diagonal into 1/2-inch thick slices
1/2 cup extra -virgin olive oil, divided
1 1/2 tablespoons Fennel Spice, recipe follows, or 1 tablespoon fennel seed, crushed in a mortar or spice grinder
6 to 8 cloves garlic
Sea salt, preferably gray salt

Cooking Recipe:

Preheat oven to 425 degrees F.

Prepare all vegetables and place in a large bowl. Cover generously with olive oil and Fennel Spice Rub. Cover and toss well to combine.

Heat a very large ovenproof skillet (that is a heavy bottomed saucepan) over high heat. Add 1/4 cup of the olive oil. When the oil is hot, add the carrots and cook for about 1 minute, then add the onions and cook, turning occasionally with tongs, until the vegetables are nicely browned, about 10 minutes. Reduce the heat if needed to keep them from burning.

Add the fennel bulb, zucchini, additional Fennel Spice Rub or crushed fennel seed, and salt, to taste. Toss well to distribute the seasonings. Drizzle with the remaining 1 tablespoon oil and toss again. Transfer the skillet to the oven and roast until the vegetables are deeply caramelized, 20 to 25 minutes, stirring them occasionally so they cook evenly. Serve immediately.

Fennel Spice Rub:
1 cup fennel seeds
3 tablespoons coriander seeds
2 tablespoons white peppercorns
3 tablespoons kosher salt

Put the fennel seeds, coriander seeds, and peppercorns in a heavy pan over medium heat. Watch carefully, tossing frequently so the seeds toast evenly. When light brown and fragrant, pour the seeds onto a plate to cool. They must be cool before grinding, or they will gum up the blades.
Pour the seeds into a blender and add the salt. Blend to a fine powder, shaking the blender occasionally to redistribute the seeds. Store in a tightly sealed glass jar in a cool, dry place, or freeze.
