Almost Homemade Roast Beef Sandwiches

My sister once brought up almost homemade when I was using a frozen meal and jazzing it up to serve at a family reunion. One night I was wanting some hot roast beef sandwiches like these: Hot Roast Beef Sandwiches.¬†However I didn’t have any roast cooking in the crock pot but then I came up with an idea.


1 package Oscar Mayer sliced roast beef lunch meat

1 package fresh mushrooms

1 sliced onion, I used about half an onion

1 package onion soup mix

sliced provolone cheese

hoagie rolls

Onion soup mix

Fix the envelope of onion soup mix as directed then add half of that to a skillet then add the roast beef.

This allows the roast beef to heat up without drying it out and it gives it some flavor. While the beef heats up place the sliced mushrooms in a skillet with butter and place the onions in another skillet with butter.

Once the onions were perfectly caramelized and the mushrooms sauteed I mixed them together.

I used the skillet that held the onions and heated it back up adding a bit more butter. I the laid the sliced rolls face down and slightly toasted them once at a time till all were crispy and hot.

After that it was simply a matter of arranging the sandwiches with juicy layers of meat, onions and mushrooms, and cheese on top of those crispy rolls. I split the remaining onion soup mix into small bowls to use as a dip.

Almost Homemade Roast Beef

ready to eat!

I call this almost homemade since I bought the meat instead of cooking my own. They turned out delicious, not as good as with homemade roast beef, but still tasty and they satisfied my cravings! These cooked in less then thirty minutes


#1 you can add anything you want to those sandwiches like sauteed green bell peppers or anything else your mind can come up with.

#2 You can use any lunch meat you want from ham to turkey to chicken breast…the possibilities are endless! I may try ham with sharp cheddar cheese next time I bet it will be just as delicious!

I also like this because it lets me use up the odds and ends in the fridge. All I had to buy was the bread since I had gotten the meat on sale and the mushrooms and onions were starting to get old….I love using up things on hand instead of tossing money in the trash by wasting food.


Hot Roast Beef Dip Sandwiches

Last night my boyfriend and I finished up moving his things to either my home or the storage shed we rented. I knew at the end I would be to tired to cook so I put a roast in the crock pot for dinner that night. However I was really tired and didn’t even want to make the proper sides for the roast…you know potatoes and veggies. So I put the roast in the fridge and made some quick (i.e. frozen meals) for dinner. So tonight I pulled the roast out and proceeded to make some hot roast beef sandwiches with onion dip.

The inspiration pin:

Now since the roast was already cooked and since I didn’t have condensed french onion soup I used the pin for inspiration only.

I sliced the onions and combined them with butter in a sauce pan to caramelize them nicely. I did the same thing with the sliced mushrooms so they would sautee nicely in their own pan.

While these were cooking I put some water in the bowl containing the roast and heated it up in the microwave. Once it was heated up I shredded it and put it aside for later. All the while I was stirring the contents of both pans so nothing would burn then I cooked the onion soup up according to the package directions.

I sliced up several french steak rolls and put them in the oven set to 250 degrees and cooked them for 10 minutes, or until crisp. You could heat them up for 20 seconds in the microwave but they turn out soft and chewy…so it’s all about your preferences…I prefer crisp, crusty bread for my dip sandwiches. After everything is cooked and ready to go you can either assemble the sandwiches or serve them smorgasbord style and let everyone make theirs how they like it. I put the cooked ingredients on the table and let my family pile them up how they like it.

These were some of the most tasty, tender, and delicious roast beef sandwiches I have ever made. I used to use the drippings of the roast as my dip and I never considered using onion soup mix before. The pin I found used condensed onion soup but I didn’t have that, and as you know I am a fan of using or reusing what you have on hand, but I had powdered onion soup mix. I thought it tasted really, really delicious! I will definitely be using this dip from now on instead of using the roast drippings…or maybe one day I will tinker with using both to get some really flavorful dip!

I hope you enjoy this as much as I do!

Happy Pinning!
