Ingredients
For the Slow-Cooked Beef
- 2½–3 pounds beef chuck roast
- 1 large yellow onion, thinly sliced
- 3 cloves garlic, minced
- 3 cups beef broth
- 1 packet au jus gravy mix
- 1 tablespoon Worcestershire sauce
- 1 teaspoon dried thyme
- ½ teaspoon dried rosemary
- ½ teaspoon black pepper
- ½ teaspoon salt, or to taste
- 1 tablespoon olive oil
For the Sandwiches
- 8 slices sturdy bread, such as sourdough or French bread
- 8–12 slices provolone cheese
- 4 tablespoons softened butter
- 1–2 tablespoons mayonnaise, optional
- Cooked onions from the slow cooker
- Shredded beef
How to Make Crockpot French Dip Grilled Cheese
1. Sear the Beef
Heat the olive oil in a large skillet over medium-high heat.
Season the chuck roast lightly with salt and black pepper.
Sear the beef for approximately 2–3 minutes per side, until nicely browned.
This step is optional, but browning the beef adds a deeper, richer flavor to the finished sandwich.
2. Prepare the Slow Cooker
Place the sliced onions and minced garlic in the bottom of your crockpot.
Put the seared beef roast on top.
Pour in the beef broth and Worcestershire sauce.
Sprinkle the au jus seasoning, thyme, rosemary, black pepper, and remaining salt over the beef.
3. Slow Cook
Cover and cook on:
- LOW: 7–8 hours
- HIGH: 4–5 hours
The beef should be extremely tender and easy to shred with a fork.
4. Shred the Beef
Remove the cooked roast from the crockpot and place it on a cutting board.
Use two forks to shred the beef into bite-sized pieces.
Return some of the shredded beef to the slow cooker juices to keep it moist and flavorful.
Reserve the cooking liquid for dipping.
5. Prepare the Bread
Spread softened butter over one side of each slice of bread.
For an extra creamy grilled cheese, you can spread a thin layer of mayonnaise on the inside-facing sides of the bread.
6. Assemble the Sandwiches
Place one slice of bread butter-side down in a skillet.
Add a generous layer of shredded beef.
Top with caramelized onions and 2–3 slices of provolone cheese.
Place another slice of bread on top with the buttered side facing outward.
Don’t overfill the sandwich, or it can become difficult to flip.
7. Grill Until Golden
Heat a skillet or griddle over medium-low heat.
Cook the sandwich for approximately 3–4 minutes per side, pressing gently with a spatula.
Flip carefully once the bottom is golden brown and crisp.
Continue cooking until the second side is golden and the cheese is completely melted.
Cooking over medium-low heat allows the bread to become crispy while giving the cheese enough time to melt.
8. Serve With Au Jus
Transfer the hot sandwiches to a cutting board.
Slice them in half and serve immediately with small bowls of the reserved beef broth for dipping.
Dip each bite into the rich au jus for the classic French dip experience.
Best Cheese for French Dip Grilled Cheese
Provolone is the classic choice because it melts beautifully and has a mild, slightly tangy flavor.
You can also try:
- Swiss cheese
- Mozzarella
- Gruyère
- Monterey Jack
- Havarti
- White cheddar
For extra flavor, use a combination of provolone and mozzarella.
Tips for the Best Sandwich
Use Chuck Roast
Chuck roast has enough marbling to remain tender and juicy during slow cooking.
Don’t Skip the Searing
While optional, searing the beef creates a flavorful browned crust that adds depth to the au jus.
Cook Low and Slow
The LOW setting generally produces exceptionally tender beef. Don’t rush the cooking process.
Use Sturdy Bread
Sourdough, French bread, Italian bread, or thick-cut sandwich bread works better than very thin slices because the sandwich contains juicy beef and au jus.
Cook Over Medium-Low Heat
High heat can burn the bread before the cheese melts. Give the sandwich time to become golden and crisp.
Don’t Skip the Dip
The savory cooking liquid is one of the best parts of this recipe. Strain it if desired and serve it warm alongside the sandwiches.
Delicious Variations
Garlic Butter French Dip
Mix minced garlic and parsley into the softened butter before spreading it onto the bread.
Mushroom French Dip
Sauté sliced mushrooms and add them to the sandwich with the beef and cheese.
Spicy French Dip
Add sliced jalapeños or banana peppers along with pepper Jack cheese.
Caramelized Onion Version
Cook the onions longer until deeply golden and sweet before adding them to the sandwich.
Cheesy Three-Cheese French Dip
Combine provolone, mozzarella, and Swiss cheese for an extra-cheesy sandwich.
What to Serve With French Dip Grilled Cheese
Pair these sandwiches with:
- French fries
- Potato wedges
- Onion rings
- Coleslaw
- Green salad
- Roasted vegetables
- Pickles
- Potato chips
- Tomato soup
For a hearty comfort-food meal, serve the sandwich with crispy fries and a bowl of warm au jus.
Storage and Reheating
Store leftover shredded beef separately from the assembled sandwiches in airtight containers in the refrigerator for up to 3–4 days.
For the best results, assemble and grill fresh sandwiches when you’re ready to eat.
Reheat the beef gently in some of the au jus before making another sandwich.
Frequently Asked Questions
Can I use another cut of beef?
Yes. Chuck roast is ideal, but bottom round or rump roast can also work. Chuck generally produces the most tender and flavorful result.
Can I skip the searing step?
Yes. You can put the raw seasoned roast directly into the crockpot, although searing gives the beef a richer flavor.
What bread is best?
Sourdough, French bread, Italian bread, or sturdy Texas toast-style bread are excellent choices.
Can I make the beef ahead of time?
Absolutely. The slow-cooked beef can be prepared a day ahead and refrigerated. Reheat it gently in the au jus before assembling the sandwiches.
