Ingredients for Slow Cooker Ground Beef French Dip Sandwiches

Beef Mixture

For the base of these slow cooker French dip sandwiches, we’re swapping the traditional beef chuck roast with ground beef for quicker cooking times and easier prep—without losing any flavor.

• 2 pounds lean ground beef – browns evenly in a large skillet over medium heat
• 1 large yellow onion, thinly sliced – adds sweetness and savory depth
• ½ cup quick-cooking oats – thickens the meat mixture without drying it out

Seasonings & Liquid

This flavorful blend creates the rich taste you expect from classic crockpot French dip sandwiches, including that signature au jus sauce for dipping.

• 1⅓ cups beef broth – adds flavor and juicy tenderness to the beef
• 1 envelope (1 oz) beefy onion soup mix – infuses bold onion-rich seasoning
• 1 tablespoon Worcestershire sauce – delivers a rich umami kick
• ½ teaspoon garlic powder – balances the beef with aromatic spice
• ½ teaspoon freshly ground black pepper – adds mild heat and earthy flavor

Assembly

Finish your French dip sandwich recipe with melty cheese and buttery-soft buns that soak up those delicious meat drippings.

• 6 slices provolone cheese – or swap with Swiss or mozzarella to melt the cheese differently
• 6 brioche burger buns or slider rolls – perfectly soft, slightly sweet, and ideal for dipping

Instructions

1. Brown the meat: In a large skillet over medium heat, cook ground beef and sliced onions until the beef is browned and no longer pink. Break up the beef using a wooden spoon for even texture.

2. Drain and transfer: Remove excess grease, then add the cooked beef mixture to your slow cooker, spreading it evenly.

3. Mix in flavor: Stir in oats, beef broth, onion soup mix, Worcestershire sauce, garlic powder, and black pepper. This forms a rich base and helps the oats thicken the mixture.

4. Slow cook: Cover and cook on low for 3 to 4 hours. This allows the ingredients to fully combine and develop a deep, savory flavor.

5. Melt the cheese: 15–20 minutes before serving, place provolone cheese slices over the top. Re-cover and let the cheese fully melt into the mixture.

6. Toast and assemble: Lightly toast the buns on a skillet or under the broiler. Spoon the cheesy beef mixture onto each bottom bun, cover with the top, and serve with a small bowl of warm au jus sauce from the cooker.

Notes & Variations

• Quick oats add body without changing the flavor profile.
• Swap provolone cheese with your favorite melty alternative like mozzarella or Swiss.
• Store leftovers in an airtight container; they freeze well for up to 3 months.
• Add caramelized onions, sautéed mushrooms, or even jalapeños for extra flavor and texture.

Tools You’ll Need

• Large skillet
• Slow cooker (4–6 quart)

What Makes Them Work

Replacing beef chuck roast with ground beef offers a fast and flexible version of this classic sandwich. Oats act as a thickening agent, absorbing flavorful juices, while beef broth and soup mix build deep umami. Layering melted cheese directly onto the warm beef keeps everything rich and satisfying. The final touch—dipping into au jus sauce—takes it to the next level.

Getting Them Made

Browning your meat first gives it a caramelized base. Transferring to the crockpot with seasonings and oats allows it to simmer slowly and soak up every bit of flavor. Melting the cheese in the final minutes ensures it’s creamy but not overcooked. Toasting the buns last adds texture and prevents sogginess from the juicy filling.

You Need to Know

• Pre-slicing onions saves time and ensures even cooking.
• Toasting buns is optional but helps them hold up better to the juicy filling.
• For best results, skip pre grated cheese and slice fresh from a block or deli.
• Adjust salt based on your soup mix—some are saltier than others.

Perfect Serving Ideas

Pair these crockpot French dip sandwiches with:

• Thick-cut fries or seasoned tater tots
• Crunchy coleslaw or tangy pickle spears
• A crisp green salad with balsamic or ranch
• A warm cup of soup for cooler evenings

Making Them Different

This recipe is a great base for creativity. Try:

• Spreading spicy mayo or horseradish sauce on the buns
• Adding shredded beef for more texture variety
• Using crusty sandwich rolls instead of brioche
• Mixing in sautéed peppers, mushrooms, or spinach
• Topping with jalapeños for heat

Storage and Reheating

• Store beef and leftover au jus sauce in airtight containers
• Refrigerate for up to 3 days
• Freeze in meal-sized portions for up to 3 months
• Reheat in a saucepan with a splash of broth or in the slow cooker on low
• Toast fresh buns to restore texture when reheating

Slow Cooker Success Tips

• Drain grease thoroughly before transferring to prevent excess oil
• Add cheese only in the last 15–20 minutes to melt the cheese without drying it out
• Keep the lid on during cooking—removing it reduces temperature and affects cooking
• If using a high-heat slow cooker, start checking at the 3-hour mark
• Taste before serving and adjust seasoning, especially if you prefer a saltier finish
