Amazing Hot Roast Beef Sandwich, made with tender roast beef from my leftover roast, topped with homemade onion rings, slathered in a rich gravy.


This hearty sandwich comes together with fresh french bread and homemade onion rings. The onion rings are so light and crispy and make the perfect topping for a hot roast beef sandwich.

Hot Roast Beef Sandwich

Ingredients
- For Onion Rings:
- 1 large onion cut into thin slices
- 1 ¼ cups all-purpose flour

- left-over au jus from slow cooker roast or any packaged au jus or beef gravy you like

Instructions
- Slice beef into thin pieces, using my electric knife works awesome for this job.
- Place roast beef slices into roasting pot, pour in left-over au jus or prepared gravy, mix together and warm up in oven for 30 mins. at 300 degrees.
- If your au jus is too thin, thicken with a bit of gravy thickener, before adding beef.
- Turn temperature to low and keep warm until ready to use.
- Prepare onion rings while the beef warms up.
- Heat the oil in a deep pot (you can also use a deep fryer)
- Separate the onion slices into rings, and set aside.
- In a small bowl, stir together the flour, baking powder and salt.
- Dip the onion slices into the flour mixture to coat; set aside.
- Whisk the egg and milk into the flour mixture using a fork.
- Dip the floured rings into the batter to coat.Then dip into the bread crumbs
- Fry in oil until golden brown 2-3 minutes
- Remove to paper towels to drain.
- Assemble by cutting thick slice of French bread, top with slices of roast beef, cover with gravy and top with onion rings.

I love onion rings and steer away from making them for the exact same reason. The clean up. I'll have to try this on the stove top.
Laureen says
Yes worked great, just small batches at a time, I might actually try some recipes that require deep frying using this method.

This is a fantastic sandwich! I love those onion rings. I do mine exactly the same way except I use beer instead of milk. There are never any left. 🙂
