At Vedge, Landau draws from the rich traditions and techniques of classic French cooking. "We pay a lot of respect to that foundation," he says. "In a way, we're making a statement that, just because we're removing animal products doesn't mean we have to stop and establish a whole new type of technique." In Landau's take on the French bistro standard steak frites, he makes a terrific red wine sauce without butter or veal stock. The meaty mushrooms stand in for steak. 

Portobello Frites
(Serves 4)

• 2 russet potatoes, scrubbed
• 1 tsp coarse sea salt
• 1/4 cup olive oil
• 2 tsp salt
• 1 tsp minced garlic
• 1 tsp freshly ground black pepper
• 1 tsp minced shallots
• 4 portobello mushrooms, stems removed, caps wiped clean
• 1 cup dry red wine
• 1/4 cup vegetable stock
• 1 tsp Dijon mustard
• 1 tbsp chopped fresh tarragon
• 1/4 cup canola oil for frying

Step One
Preheat the oven to 400° F. Puncture each potato with a fork three times, sprinkle each with 1/2 tsp of 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.

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

Step Three
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 with rounded sides up. Roast until soft in the middle, 8 to 12 minutes.

Step Four
Transfer the portobello caps to a plate, still rounded sides up, and set aside to cool. Pour the wine, vegetable stock, and mustard onto the warm sheet pan to mix with the mushroom cooking juices. Scrape any solids off the tray using a wood spoon, then carefully pour this mixture into a large saucepan. Heat the mixture over medium heat until reduced by half, 8 to 10 minutes.

Step Five
Stir the tarragon into the red wine sauce. Remove the saucepan from the heat and cover to keep warm.

Step Six
In a large sauté pan, heat the canola oil over high heat. When the oil is very hot, carefully fry a few potato wedges at a time until they turn brown on all sides, about 6 minutes. Transfer the frites as they are done to a plate lined with paper towels and sprinkle them lightly with the remaining 1 tsp salt.

Step Seven
Reheat the portobello caps in the oven if necessary. Serve smothered with red wine sauce and frites on the side.
