The Ingredients You Will Need

The ingredients for the incredible sandwich are simple and many you’ll probably already have in your pantry. Here’s what you’ll need to have on hand:

Beef roast – We recommend a nicely marbled chuck roast. However, you could substitute a top round roast, bottom round roast, or a tri tip roast for equally delicious results.
Seasonings – Salt and pepper.
Onion – Chopped.
Garlic – Minced.
Beef stock or brothHomemade or purchased are both perfectly fine.
Soy sauce – Regular or low-sodium are both excellent choices.
Worcestershire sauce – We love Lea & Perrins which is available in the condiments section of most supermarkets.
Dried herbs – Herbs de Provence or dried thyme are both wonderful choices.
Buns – Soft French buns or hoagie buns are perfect.
Sliced cheese – Provolone is what we recommend, but you could also go with sliced Muenster, gouda, or even mozzarella.

EXPERT TIP: Searing the roast before adding it to the slow cooker creates a nice crusty exterior called the Maillard Reaction. It does add a depth of flavor, but, if you are in a crunch for time, you can skip searing the roast and go directly to the slow cooker. But, try and find the time, if possible.

Tips for Making Perfect Slow Cooker French Dip Sandwiches

Don’t Overcook the Roast – We love a roast that is so tender it completely shreds when barely pulled apart with a couple of forks. For a French dip, you want layers of meat. Cooking the roast on LOW for 9 hours gives you extremely tender beef, but not so much that it can’t be sliced.

Choose the Right Buns – For that authentic taste and texture, find buns that are soft. Hoagies and soft French bread are ideal. Crusty Italian loaves or baguettes are just fine but harder to bite into.

Toast the Buns – This isn’t completely necessary, but it gives a slightly crunchy interior to the inside edges of the bread which are an amazing contrast to the tender meat and melty cheese.

Strain the Liquid – Don’t skip this step. The au jus will be thin and should only be broth. If desired, use a fat separator to get rid of excess fat in the au jus. But, remember, there’s a lot of flavor in that fat!

EXPERT TIP: For optimal flavor, we place the chopped onions on the bottom of the pot and place the seared roast on top of them. Then, add the minced garlic on top of the roast and cover with the broth mixture. No need to sauté the onions and garlic, they will cook perfectly and impart flavor.

How To Serve

When serving friends and family, you can go ahead and assemble the sandwiches and serve them piping hot, right after toasting the buns and melting the cheese under the broiler.

To avoid communal double-dipping, we recommend providing a small bowl of au jus for each person and their sandwich.

Or, you can place the sliced meat back in the slow cooker, pour a little of the au jus over the meat, and then set the toasted buns and cheese slices on a platter and let guests build their own sandwiches.

Remember, you want to cook the meat long enough so it is extremely tender, but not completely fall apart. It should be juicy, but still be able to slice with a sharp knife.
