[Leftover] Pot Roast French Dip Sandwich
with mixed greens salad

Active: 40 Total: 40

A French Dip is a warm toasted sandwich filled with tender beef, topped with melted cheese, and dipped in flavorful au jus. To build flavor in Monday's leftover pot roast, saute it with onions before adding it to the sandwiches. This meal was last featured in 2021
Smarts: The au jus used for dipping should still be quite thin, but adding a bit of cornstarch helps it to adhere to the sandwiches.

Make

  1. Turn on the oven’s broiler. Place a rack 6” / 15 cm beneath the heat source.

  2. While broiler is heating, melt first portion of butter in a skillet or saute pan over medium heat. To melted butter, add onions with some salt. Saute until onions are translucent and very tender, 5 to 6 minutes. Add leftover pot roast and saute until heated through, 4 to 5 minutes more. Set meat / onions aside and return pan to heat.

  3. To heated pan, slowly add cooking liquid, scraping up any browned bits on the bottom of the pan. Whisk together soy sauce and cornstarch. When cooking liquid is simmering, whisk in soy sauce / cornstarch and cook for 1 minute. (It should still be quite liquid-y but the cornstarch will help it adhere a bit better to the sandwiches.) Pour au jus into small bowls for serving.

  4. Place baguette cut-side up on a sheet pan. Spread with second portion of butter and transfer to oven until lightly toasted, 2 to 3 minutes.

  5. Fill sandwiches with meat and top with sliced cheese. Broil until cheese is melted, 2 to 3 minutes more.

  6. Just before serving, toss greens with vinaigrette.

  7. Serve sandwich with au jus for dipping and salad on the side. Enjoy!

The "I have low energy" version: I skipped the au jus and just splashed a little soy sauce in with onions/mushrooms at the end of cooking. Instead of the side salad, I put the greens and some dijon/vegan mayo on the sandwich.

It came together quickly for a leftover meal but it had a lot of clean up. Well worth the effort. It was moist and went well with the simple salad. Made it with the dip and baguette. Very filling.
