Portobello Frites

1. Preheat the oven to 400°F. Puncture each potato with a fork three times, sprinkle each with 1/2 teaspoon of the coarse sea salt, and wrap individually in foil. Bake until tender to the touch, about 40 minutes. Unwrap the potatoes and let cool; when cool enough to handle, cut each into eight wedges. Set aside.

2. While the potatoes are cooling, whisk together the olive oil, 1 teaspoon of the salt, the garlic, pepper, and shallots in a small bowl.

3. Place the portobello caps on a sheet pan with rimmed edges and coat them evenly on both sides with the olive oil mixture, leaving them rounded sides up. Roast until soft in the middle, 8 to 12 minutes.
