How to Make a French Dip Sandwich
Though this may seem like a difficult meal to make, it’s really so simple. The crock pot makes it really easy and always cooks the meat to perfection! Here’s how to make a homemade french dip sandwich:
Make the Meat
First things first, start by removing the roast from the fridge and let it sit at room temperature for about 15 minutes. Then, season it with salt, pepper and onion powder.
Next, add olive oil to a large skillet and heat over medium heat. Once hot, place the seasoned roast into the hot skillet and sear it on all sides.
Remove the roast from the skillet and place into the slow cooker. Then sprinkle the au jus seasoning over the roast and pour a beer over it.
Place the lid onto the slow cooker and cook on low for 8 hours.
Once the 8 hour cooking time is up, transfer the meat to a plate and shred it. It is typically tender enough that it just falls apart, so use two forks and gently pull it apart to shred.
Prepare the Bread
Next, set your oven to broil and place the hoagie rolls onto a baking sheet.
Mix the butter and garlic powder together in small bowl and brush over rolls. Then broil the hoagie rolls on low heat until just golden brown.
Remove from oven and pile with shredded french dip meat and top with provolone cheese. Return to oven and broil until cheese is melted.
Top sandwiches with fresh parsley if desired.
Strain the Au Jus
Using a fine mesh strainer, strain the liquid over a bowl to get any chunks out of it.
Then I serve it in my favorite Ramekin dishes so it’s easy to dip your sandwich in!
Immediately serve the sandwiches while hot and enjoy!
How to Store Leftover Beef from this French Dip Recipe
FRIDGE: Place leftover roast beef into an airtight container and store in the fridge for up to 4 days. Do not store meat on the toasted bread, as it will get soggy in the fridge. Au jus can be stored separately in an airtight container or mason jar.
Store leftover toasted bread at room temperature in an airtight container or tightly sealed zip top plastic bag.
FREEZER: You can also freeze leftover beef and au jus. Store in separate airtight containers and freeze for up to 3 months. Allow to thaw in the fridge before reheating.
How to Reheat Leftovers
To reheat, place meat into the microwave or on the stove top. Toast buns just as the recipe calls for, then add the reheated meat and sliced cheese to bread and broil until cheese is melted. Reheat au jus on stove top or in the microwave and serve.
What to Serve with Slow Cooker French Dip Sandwich
There are so many crave-able side dishes that you can serve with french dip sandwiches. Crack potatoes are one of my favorites! The flavors pair so well together…dangerously addictive.
You could serve a healthier option like this southwestern salad or some tasty skillet asparagus. Serve a more classic side dish like sweet potato fries or air fryer french fries for a nostalgic combo!
What can I do with leftover beef?
Here are a few quick ideas to use up leftover roast beef if you have it left! Of course, you can always make a french dip sandwich from leftover, but there are tons of other options too.
Make a quick Minute Steak Sandwich by frying thin slices of your roast beef in a skillet then putting them on top of a baguette. Top that with sautéed onions and cheese then toast it under the broiler.
Another great idea is to make a twist on sloppy joe. Simply chop up the roast beef, then simmer with chopped onions, garlic, tomato sauce and light brown sugar to make a sloppy joe. Pile it on top of a sandwich bun!
Personally, I’m really boring and I love it cold, piled with ketchup on a bun. It’s one of those comfort foods I remember from childhood!
- Get the freshest hoagie rolls you can find for the most delicious flavor! Check the bakery section in your local grocery store or even you local bakery.
- If you don’t have a fine mesh strainer, strain the au jus through cheese cloth to get it just as smooth.
- Serve with extra toppings to get the best combo of flavors that you want! Grilled onions, pepperoncini peppers, mayonnaise, etc.
This easy recipe is a go-to classic that the whole family will enjoy!
