Roast Beef or Grilled Steak Options
We love sandwich night in our house and these Easy French Dip Sandwiches are no exception! They are a simple weeknight dinner and super family friendly. The kids pick out the onions of course, but love dunking them in the sauce!
I originally wrote this recipe using sliced roast beef from the deli. It’s fast, it’s easy, it works. But, when I tried the same recipe with an affordable cut of grilled steak, WOW! It’s amazingly delicious! So there are a couple options and a couple ways to proceed.
Method 1 – Deli Roast Beef
What I’m calling Method 1 is the simple version using roast beef from the deli. Caramelize an onion in olive oil in a skillet over low heat. This is a slow but easy process, just stir occasionally while the natural sugars in the onion turn it from white to golden brown. When they achieve a nice deep color, add stock and let it simmer to reduce a bit. Add in your roast beef, just for a minute to warm. Then, assemble your sandwiches on hoagie buns with the beef and onions, top with cheese and broil until toasted and melty. While the sandwiches broil, continue to reduce the au jus sauce and serve each person a little cup for dipping. Be sure to cut your sandwiches in sharp triangles for easy dunking!
Method 2 – Grilled Steak
An affordable cut of steak, such as a 1 pound sirloin, is delicious in place of the roast beef. It will make enough for 2 to 4 sandwiches, depending on how full you load them. Caramelize the onions the same as above, and while they are cooking, grill the steak, seasoned with olive oil, salt and pepper on an outdoor grill. Cook it just to medium rare, about 4 to 5 minutes per side, and let it rest on a cutting board. Slice it thin and add to the au jus just before assembling the sandwiches so you don’t overcook it. It’s an extra step, but super delicious, so give both versions as try!
Method 3 – Steak Indoors in a Cast Iron Skillet
You can also cook your steak indoors in a cast iron skillet. If you use this method, I would basically do the whole process in reverse. Start by searing the steak in a hot skillet, about 4 to 5 minutes per side. When you flip it, add the sliced onions to the pan around it. When the steak is done, remove it to a cutting board, lower the heat and continue cooking the onions until caramelized. Then add the stock and simmer to reduce. You can then slice the steak, add it back to the sauce and assemble the sandwiches.
Easy French Dips are the perfect sandwich night! That crusty bread, softened when dunked with the gooey cheese has me hooked! Paired with a simple side dish, they will quickly become a family favorite!

Easy French Dip Sandwiches
- 1 T olive oil
- 1 onion sliced
- ¼ t kosher salt
- 6 grinds fresh black pepper
- ¾ lb deli roast beef, thinly sliced (OR a 1 pound sirloin steak)
- 1 quart beef stock
- 2 to 4 hoagie buns

- To Caramelize Onions--set a saute pan over medium low heat, add olive oil and cook onions, seasoned with salt and pepper, slowly for 20 minutes or more, stirring occasionally until they turn caramel brown in color.
- When caramelized, add stock, allow to simmer and reduce, about 10 minutes.
- When stock is reduced a bit, lay sliced roast beef over the onions and stock and allow to warm through. Turn oven broiler on high.
- STEAK OPTION--While the onions are caramelizing, you can alternatively cook a steak on an outdoor grill, allow it to rest on a cutting board before slicing and adding to the reduced stock. See Method 2 and 3 in text above.
- Assemble sandwiches on a large sheet tray with tongs, fill hoagies with roast beef, onions, and top with cheese. Broil until cheese is melted and hoagies are toasted. Meanwhile turn up heat to medium to reduce the beef stock and onion mixture further, this will be your dipping sauce.
- Cut sandwiches diagonally to allow for easy dipping! Serve everyone their own little cup of sauce.
