Best Vegetarian French Dip Sandwiches Recipes

VEGETARIAN FRENCH DIP SANDWICHES

Steps:

• Slice the onion into thin strips. Rinse the portobello caps to remove any dirt or debris. Slice each cap in half, then crosswise into 1/4-inch thick strips.
• Add the butter to a deep skillet along with the sliced onions. Sauté the onions over medium heat for a few minutes, or just until they begin to soften.
• Add the sliced mushrooms to the skillet along with the salt, pepper, thyme, and oregano. Sauté the mushrooms until they release all their moisture and the liquid in the bottom of the skillet has evaporated (about 10 minutes). You should see some browned bits coating the bottom of the skillet.
• Add the vegetable broth, soy sauce, brown sugar, and garlic powder and stir to dissolve the browned bits from the bottom of the skillet. Allow the liquid to come up to a simmer, then turn down to low and simmer for about 5 minutes while you toast the bread.
• Open the rolls and place them on a baking sheet, open sides up. Turn the oven on to broil and place the rolls in the oven on the middle rack. Watch the rolls closely and broil just until you see a slightly browning on the edges (about 5 minutes).
• Use a slotted spoon or tongs to take the mushrooms and onions out of the au jus. Divide the mushrooms and onions among the four rolls. Top each sandwich with a slice of provolone.
• Return the sandwiches to the oven and broil for a few minutes more, or just until the cheese is melted. Close the sandwiches up and serve with the au jus from the skillet for dipping.

VEGAN FRENCH DIP SANDWICHES

Steps:

• Coat the bottom of a large skillet with 1 tablespoon of oil and place over medium-low heat. Add onion and toss a few times to coat with oil. Allow to cook until caramelized, about 20 minutes, flipping occasionally. Add garlic and cook about 2 minutes more. Transfer onions and garlic to a plate.
• Coat skillet with another tablespoon of oil and raise heat to medium. Add mushroom strips. Avoid overcrowding the skillet. A little overlapping is okay, but work in multiple batches if needed (I needed two), adding a bit of oil between batches if needed. Cook until lightly browned, about 5 minutes. Flip and cook 5 minutes more on opposite sides.
• Return onions to skillet and add broth, soy sauce, Worchestershire sauce, thyme, liquid smoke and pepper. Bring to a simmer and allow to cook, stirring occasionally, until liquid is reduced by half, about 5 minutes.
• Slather the insides of rolls with horseradish mustard. Use a slotted spoon to remove onions and mushrooms from skillet, pressing lightly to squeeze out any excess juice. Divide onions and mushrooms into rolls. Pour cooking liquid into a small bowl and serve with sandwiches, for dipping.

MUSHROOM FRENCH DIP

Steps:

• Heat 1 tablespoon oil in a large cast-iron or heavy skillet over high heat. Add onion and cook, stirring frequently, until lightly browned, 3 to 4 minutes. Add garlic and cook until fragrant, about 1 minute. Transfer to a medium bowl.
• Add 1 tablespoon oil to the pan. Add portobellos and cook, stirring occasionally, until browned, 5 to 6 minutes. Transfer to the bowl. Add the remaining 1 tablespoon oil and oyster (or shiitake) mushrooms to the pan. Cook, stirring occasionally, until browned, 5 to 6 minutes. Return the portobellos and onion to the pan. Stir in mustard and thyme; cook for 1 minute. Stir in broth and sherry and simmer for 5 minutes.
• Position a rack in upper third of oven; preheat broiler to high.
• Scoop out most of the inside of the rolls (reserve for making breadcrumbs, if desired). Place the rolls cut-side up on a baking sheet. Using a slotted spoon, divide the mushroom mixture among the bottom halves of the rolls (reserve the sauce). Top with cheese.
• Broil until the cheese is bubbly and lightly browned, 1 to 2 minutes. Place the top halves of the rolls on the sandwiches and serve with the sauce.

VEGETARIAN PORTOBELLO FRENCH DIP SANDWICH

Steps:

• Mushroom Essence: Combine the mushrooms, garlic, and 6 cups of water in a 3 quart saucepan. Bring to a boil, then lower the heat and simmer for about 1 1/2 hours, until the liquid has been reduced to 1 1/2 - 2 cups.
• Strain the liquid and add the tamari. Keep warm if using immediately, or refrigerate/freeze.
• French Dip Spread: Heat the olive oil in a small skillet over medium heat. Add the shallot, garlic, and herbs and cook for two minutes, stirring as you go. Add the wine and cook until mostly evaporated, but still moist. Remove from the heat and cool to room temperature. Add the cooled shallot mixture to the softened butter and mix well. Add salt and pepper to taste. Makes 1/2 cup.
• The Sandwich: Preheat the oven to 350°F Mix 2 tbsp of the olive oil and the garlic together in a small bowl. Brush mixture on both sides of the portobello caps, and sprinkle with salt and pepper. Place them gill sides down on a baking sheet, and roast for 25 minutes.
• When the mushrooms are cool enough to handle, slice each cap thinly at an angle, about 8-10 slices per cap.
• While the portobello caps are in the oven, heat the remaining 1 tbsp oil in a pan over medium heat. Add the onion and cook for about 5 minutes, until it begins to soften. Turn the heat to low and cook the onion for 15-20 minutes, stirring occasionally. If it begins to stick, add 1-2 tbsp of sherry or water to the pan.
• Cut the baguette into 4 equal portions 5-6 inches long, avoiding the rounded ends. Slice each in half lengthwise. Spread each of the 8 halves with 1 tbsp of the French Dip Spread. Heat a large skillet over medium heat. Place as many of the halves that will fit, spread-side down, for 3 minutes. Repeat for all the halves.
• Place 4 baguette bottom-halves, griddled side up, on a baking sheet lined with parchment paper. Top each with 1/4 of the sliced mushrooms and grilled onions. Top with cheese.
• Place in the 350°F oven for about 10 minutes, until heated through and cheese melts. Top with the remaining halves and bake for 3 minutes more.
• Slice each sandwich in half at an angle and serve with about 1/3 cup of Mushroom Essence.

VEGETARIAN FRENCH DIP SANDWICHES

Steps:

• Slice the onion into thin strips. Rinse the Portobello caps to remove any dirt or debris. Slice each cap in half, then crosswise into 1/4-inch thick strips.
• Add the butter to a deep skillet along with the sliced onions. Sauté the onions over medium heat for a few minutes, or just until they begin to soften. Add the sliced mushrooms, a pinch of salt and pepper, the thyme, and oregano. Sauté the mushrooms until they release all their moisture and the liquid in the bottom of the skillet has dried up (about 10 minutes). You want to see some of the liquid browning and coating the bottom of the skillet (but not burning).
• Once the evaporated juices begin to coat the bottom of the skillet, pour in the vegetable broth. Stir to dissolve the browned bits from the bottom of the skillet. Also add the soy sauce, brown sugar, and garlic powder. Allow the liquid to come up to a simmer, then turn down to low and simmer for about 5 minutes while you toast the bread.
• Open the rolls and place them on a baking sheet, open sides up. Turn the oven on to broil and place the rolls in the oven. Watch the rolls closely and broil just until you see a slightly browning on the edges (about 5 minutes).
• Use a slotted spoon or tongs to take the mushrooms and onions out of the au jus. Divide the mushrooms and onions among the four rolls. Top each sandwich with a slice of provolone. Return the sandwiches to the oven and broil for a few minutes more, or just until the cheese is melted. Close the sandwiches up and serve with the au jus from the skillet for dipping.
• NOTE ABOUT BROTH: The type of broth you use will greatly affect the end flavor of the au jus. I used vegetable flavored Better Than Bouillon concentrate to make my broth.
