Discovering Vegan Mushroom French Dip Sandwiches
When I first tackled making these Vegan Mushroom French Dip Sandwiches, I was on a quest to create a meal that was both comforting and packed with flavor. I had recently fallen in love with the rich umami of portobello mushrooms, and I knew they would be the perfect base for a vegan twist on the classic French dip.
I remember the first time I caramelized onions for this recipe. As the onions slowly turned a beautiful golden brown, the kitchen filled with a sweet, inviting aroma that made my mouth water. Adding the garlic and mushrooms to the pan was like an olfactory celebration. The mushrooms absorbed all those savory flavors, becoming wonderfully tender and flavorful.

The magic happened when I combined everything—the mushrooms, onions, and that deliciously seasoned broth. The kitchen smelled incredible, and I couldn’t wait to dig in. Toasting the rolls and spreading horseradish mustard added just the right amount of kick and texture.
Taking the first bite of these sandwiches, dipped in the rich, savory au jus, was a moment of pure satisfaction. Each bite delivered a delicious combination of flavors and textures that made the effort completely worthwhile. I was thrilled to share this recipe with friends, and it quickly became a favorite, proving that you don’t need meat to enjoy a hearty, satisfying meal.

Chef’s Notes – Vegan Mushroom French Dip Sandwiches
- For extra crunch, toast the sandwich rolls just before serving. This will help them hold up better when dipped in the au jus. By toasting the rolls, you are protecting the inside from going soggy by adding a hard layer outside the buns.
- Feel free to add sautéed bell peppers or spinach to the mushroom mixture for added flavor and nutrition. And, for an extra dimension of flavor, you can try charring them first before adding them.
- If you like a bit more heat, add a touch of cayenne pepper or a few dashes of hot sauce to the mushroom mixture.
- If you prefer a thicker au jus, let it simmer for a bit longer until it reduces to your desired consistency. However, Au Jus should not be too thick and should just be enough to drizzle from the back of the spoon. Reducing the AU Just can result in more concentrated flavors that can overcome your dish.
- For a fun twist, serve the Vegan Mushroom French Dip Sandwiches with a side of pickled vegetables or a simple coleslaw. Chek out some of our recipes for these like our Rainbow Red Cabbage Salad
