The cooking process explained
Now let’s dive into the delightful process of making these sandwiches. Have your slow cooker ready and your ingredients at hand—this step-by-step overview will guide you through every delicious moment.
First, we start with a beautifully marbled beef chuck roast. It’s seasoned, seared, and then allowed to bathe in a luscious broth combined with aromatic herbs. As it cooks, the flavors meld and deepen, creating that magical jus for dipping. And don’t forget the mushrooms and garlic, which bring a robust earthiness that elevates this sandwich from ordinary to extraordinary.
What you’ll need
For the Beef & Jus:
- 1 tablespoon vegetable oil
- 3 to 4 pounds beef chuck roast
- 1½ teaspoons kosher salt
- 1 teaspoon ground black pepper
- 2½ cups water
- 1 cup low-sodium beef broth
- 1 tablespoon beef bouillon paste or powder
- 1 bay leaf
- 2 packets dry onion soup mix
- ½ teaspoon dried thyme
- ½ teaspoon dried rosemary
- 4 to 6 garlic cloves, minced or lightly crushed
- 8 to 12 ounces mushrooms, sliced
For the Sandwiches:
- 6 to 8 crusty sandwich rolls
- ½ cup butter, softened (optional)
- ½ teaspoon garlic powder (optional)
- 16 ounces sliced provolone, mozzarella, or Monterey Jack cheese
- Prepared horseradish sauce
Feel free to swap out the cheeses, depending on what you have on hand or your personal preference. Monterey Jack cheese gives a nice gooey texture, while provolone adds a bit of sharpness.
Step-by-step instructions
- Heat a large skillet over medium-high heat. Pat the beef dry with paper towels and season all sides with kosher salt.
- Add the vegetable oil to the hot skillet and sear the roast for 1 to 2 minutes per side until it’s beautifully browned on the outside. This step is key—it locks in those mouthwatering juices that keep the meat succulent.
- Transfer the beef to your slow cooker and sprinkle it lightly with ground black pepper.
- In that same skillet, pour in the water, beef broth, and beef bouillon, scraping the bottom to lift any browned bits—there’s flavor in those little morsels! Once dissolved, pour this mixture over the beef in the slow cooker.
- Add the bay leaf, garlic, and sliced mushrooms around the roast. Sprinkle the onion soup mix on top, allowing some to fall into the liquid. Finish by adding the dried thyme and rosemary.
- Cover the slow cooker and let it work its magic on LOW for 8 to 10 hours, or on HIGH for 1 hour followed by 7 to 9 hours on LOW.
- Once cooked, transfer the roast to a cutting board and let it rest for a few minutes before slicing thinly against the grain for optimal tenderness.
- Preheat your broiler and place rolls cut-side up on a baking sheet. If desired, mix the softened butter with garlic powder and spread it lightly on the rolls, then broil until golden. Flip briefly to crisp the outside, then return cut-side up and top with cheese. Broil just until melted.
- Spread horseradish sauce on the melted cheese, add the sliced beef and mushrooms, and close the sandwiches. Serve hot with small bowls of the cooking jus for dipping. Ah, the drippy goodness!

Best ways to enjoy it
These sandwiches are marvelously versatile. Pair them with a side of crispy sweet potato fries or a fresh green salad to balance the richness of the beef. A tangy coleslaw can also add a crunchy contrast that complements the sandwich perfectly. And let’s not forget a cold brew or a crisp glass of red wine to elevate your meal further. Your dinner guests will rave!
Keeping leftovers fresh
If by some miracle you have leftovers, storing these French dip wonders is quite simple. Let the beef and jus cool completely before transferring them into an airtight container. They’ll be great in the fridge for 3 to 4 days. For longer storage, consider freezing the sliced beef and jus in freezer-safe bags for up to three months. Just be sure to remove as much air as possible before sealing—this helps prevent freezer burn.
When you’re ready to enjoy again, reheat the beef gently on the stove, adding a dash of water or broth to the pan to keep it moist. You’ll be thankful for this little treasure amidst the hustle of life!
Helpful cooking tips
Here are a few tips to ensure your sandwiches turn out perfectly every time.
- Searing is key: Don’t skip the searing step! It might seem like an extra bite of work, but that caramelization adds a depth of flavor that you won’t want to miss.
- Low and slow: Don’t rush the cooking time; the longer you let it cook on LOW, the more tender and flavorful your beef will be.
- Slice against the grain: This nugget of advice ensures you get the tenderest pieces of beef. Look for the lines in the meat and slice perpendicular to them.
Creative twists
Feeling adventurous? Try adding some sliced jalapeños for a spicy kick or incorporating a mix of cheeses for a melty flavor combo. You could also throw in some bell peppers for a touch of sweetness or swap out the beef for a pork roast for a different yet equally delicious take. The beauty of this recipe lies in its flexibility—make it yours!
