Slow Cooker French Dip Grilled Cheese Sandwiches

The Comfort Food Mashup My Family Requests Again and Again

I used to think French dip sandwiches were something you only ordered at restaurants.

Then my sister made them in her slow cooker on an ordinary Tuesday night, and everything changed.

She lifted the lid, and the house instantly filled with the smell of slow-cooked beef, onions, and savory herbs. The chuck roast practically fell apart with a fork. Then she did something I never expected—she piled that juicy beef between buttery slices of bread with plenty of melted provolone, grilled it until crisp and golden, and served it with a bowl of rich au jus for dipping.

One bite was all it took.

The crunchy grilled bread, the gooey cheese, the unbelievably tender beef, and that warm, flavorful broth made every sandwich taste like pure comfort.

I went back for thirds.

My husband still talks about those sandwiches whenever someone mentions grilled cheese.

Now they're one of our favorite slow cooker dinners because they look impressive, taste incredible, and require very little hands-on work.

Why This Recipe Works

The au jus mix, Italian seasoning, onions, and beef broth combine into a savory cooking liquid that becomes the perfect dipping sauce. Grilling the sandwiches with buttery bread and melted provolone creates a crisp exterior while keeping the inside incredibly juicy and cheesy.

How to Make French Dip Grilled Cheese

Step 1: Season and Sear

Season the chuck roast generously with salt and pepper.

Heat a skillet over medium-high heat with a little oil.

Sear each piece until deeply browned on every side.

Transfer the beef to the slow cooker.

Step 2: Slow Cook

Add:

• Sliced onion
• Au jus packets
• Italian seasoning
• Beef broth
• Water

Cover and cook:

• Low: 6–8 hours
• High: 4–5 hours

The beef should shred easily with a fork.

Step 3: Shred the Beef

Remove the roast.

Shred using two forks.

Return the meat to the slow cooker or keep warm separately.

Strain the cooking liquid into a bowl to create the dipping au jus.

Step 4: Assemble

Butter one side of each bread slice.

On the unbuttered side layer:

• Cheese
• Shredded beef
• Cooked onions
• Another slice of cheese

Top with the remaining bread.

Step 5: Grill

Cook each sandwich over medium heat.

Grill for about 3–4 minutes per side until:

• Bread is golden brown
• Cheese is completely melted
• Sandwich is crisp

Step 6: Serve

Slice each sandwich in half.

Serve immediately with warm au jus for dipping.

Expert Tips

Don't Skip the Sear

Browning the roast adds incredible flavor to both the beef and the broth.

Use Good Bread

Sourdough stays crisp while holding up to the juicy filling.

Fresh Cheese Melts Best

Sliced deli provolone creates the creamiest texture.

Warm the Au Jus

Serve the broth piping hot for the best dipping experience.

Delicious Variations

Swiss Cheese Version

Swap provolone for Swiss cheese.

Mushroom French Dip

Add sliced mushrooms to the slow cooker.

Garlic Butter Bread

Spread garlic butter instead of plain butter before grilling.

Spicy Kick

Add pepper jack cheese or crushed red pepper flakes.

Caramelized Onion Upgrade

Slowly caramelize extra onions and pile them onto each sandwich.

Frequently Asked Questions

Can I use another cut of beef?

Chuck roast is ideal because it becomes tender after slow cooking, but rump roast also works well.

Can I make it ahead?

Yes. The beef actually develops even more flavor overnight.

Can I use mozzarella?

You can, but provolone or Swiss provide the classic French dip flavor.

Can I cook it on high?

Yes. Cook for about 4–5 hours until fork tender.

What if I have leftover beef?

Use it for sliders, baked potatoes, tacos, wraps, or pasta.
