A sandwich-shop classic, the beef-loaded baguette and au jus combo delivers a whopping 1,450mg sodium (over 60% of your daily recommended limit), plus almost 9g sat fat.

To create a healthier handheld without forfeiting its meaty character, we use toothsome mushrooms to mimic meat’s heft and enrich the sandwich with noteworthy umami. A blanket of caramelized onions offer the perfect alchemy of sweetness and added complexity. To further infuse each bite with robust flavor, a homemade au jus gets infused with sherry wine, herbs, vegetarian Worcestershire, and soy sauce to build savory depth in minutes. Delightfully hearty and a little bit messy, our slimmed-down sandwich delivers classic satisfaction (and a full serving of veggies) for one-third fewer calories.

How to Make It

Step 1

Heat butter and 1 1/2 teaspoons of the oil in a large skillet over medium. Add onions; cook 10 minutes, stirring occasionally. Reduce heat to medium-low; cook until golden, about 30 minutes, stirring occasionally. Stir in salt; cook 5 minutes.

Step 2

Heat 1 tablespoon of the oil in a separate large skillet over medium-high. Arrange half of mushrooms in skillet in a single layer and cook, undisturbed, 3 minutes, until golden-brown. Stir and cook 5 minutes, stirring often, until both sides are golden-brown. Place mushrooms in a bowl. Repeat process with remaining 1 tablespoon oil and half of mushrooms.

Step 3

Combine all cooked mushrooms in pan. Add broth, sherry, Worcestershire sauce, thyme, soy sauce, and black pepper. Bring mixture to a boil; reduce to a simmer; cook 5 minutes. Use tongs to remove mushrooms from au jus; place in a bowl. Pour au jus evenly into 4 ramekins.

Step 4

Combine mustard and horseradish in a bowl. Spread on top halves of rolls.

Step 5

Preheat broiler to high. Arrange 3/4 cup mushrooms onto the bottom half of each roll. Add 1/4 cup onions. Tear each slice of cheese in half; place over onions. Place hoagies on a baking sheet. Broil 1 to 2 minutes, until cheese melts. Serve with au jus.
