French Dip Sandwich with Big Dipper Au Jus

Directions

1. Melt the butter in a medium nonstick skillet over medium heat, and then add the onions, tossing to coat. Cover the skillet and cook for 20 minutes, tossing every now and then.

2. Remove the lid and cook for another 20 minutes, tossing occasionally. The onions should be quite soft and starting to brown.

3. Add the sugar, vinegar, and salt and pepper and cook for another 10-15 minutes, until the onions are dark and very sticky. Remove from heat and set aside.

4. Preheat the oven to 375 degrees F.

5. Place the baguette slices (or rolls) cut-side up on a baking sheet.

6. Prepare Big Dipper Au Jus mix according to packet instructions.

7. Dip ¼ of the beef in the hot Au Jus, and then place the meat on the bottom slice of bread and top with 2 slices of provolone and some caramelized onions. Repeat with remaining beef.

8. Bake the sandwiches in the preheated oven until the cheese melts, about 5 minutes.

9. Serve sandwiches with small bowls of Au Jus for dipping.
