Introduction
When it comes to hearty and flavorful sandwiches, the French Dip stands out as a timeless favorite. Traditionally made with thinly sliced roast beef and served with au jus for dipping, this sandwich has delighted taste buds for generations. However, for those seeking a vegetarian alternative that doesn’t compromise on taste, the Portobello French Dip with Horseradish Aioli offers an irresistible solution. This gourmet twist on the classic French Dip combines the meaty texture of Portobello mushrooms with the sharp, creamy kick of horseradish aioli.
Why Choose Portobello Mushrooms?
Portobello mushrooms are an excellent meat substitute in many recipes. Their rich, umami flavor and firm texture make them ideal for grilling, roasting, and, of course, sandwiches. Portobellos also have the added benefit of being low in calories while providing essential nutrients such as potassium, selenium, and vitamin B6.

Marinating the Portobello Mushrooms
- In a large bowl, whisk together olive oil, balsamic vinegar, garlic, soy sauce, thyme, salt, and pepper.

- Mix well and refrigerate until ready to use.

Tips for Perfecting Your Portobello French Dip
- Marination Time: The longer you marinate the mushrooms, the more flavorful they will be. Aim for at least 2 hours if possible.
- Cheese Option: Swiss cheese adds a nice melt and flavor, but you can also experiment with provolone or mozzarella.
- Bread Choice: A crusty roll or baguette is essential for holding up against the au jus. Avoid softer breads that may become soggy.
Variations to Try
- Vegan Option: Replace the mayonnaise in the aioli with a vegan alternative and skip the cheese.
- Spicy Kick: Add a pinch of cayenne pepper to the horseradish aioli for some extra heat.
- Herb Infusion: Incorporate fresh herbs such as rosemary or basil into the mushroom marinade for a different flavor profile.
