Make It Your Way

One of the best things about this Slow Cooker French Dip Sandwiches Recipe is how easily it can be tailored to fit your taste buds or pantry. Whether you want to kick up the horseradish heat or add some seasonal veggies, customizing this classic is a breeze.

Spicy Kick: I love adding an extra teaspoon of horseradish to the mayo spread when I’m craving a little more zing—it really wakes up the flavors without overpowering the juicy beef.
Cheese Swap: While provolone melts beautifully, swapping in Swiss or mozzarella can give a different but equally delicious experience. I once tried smoked gouda and was pleasantly surprised by the depth it added.
Low-Sodium Option: For a lighter sodium profile, using low-sodium beef broth and reducing the added salt keeps the sandwich flavorful but gentler for your heart.
Seasonal Veggies: Toss some sautéed mushrooms or roasted bell peppers onto your sandwich for an extra layer of texture and nutrition. It’s a fun way to sneak in veggies without losing that classic French dip vibe.

Step-by-Step: How I Make Slow Cooker French Dip Sandwiches Recipe

A close-up image shows a sandwich held by a man's hand, with the sandwich about to be dipped into a white bowl filled with brown broth. The sandwich is made of a light brown bun with a filling that includes slices of cooked meat and melted white cheese visible inside. The background has a wooden surface with several more sandwiches in soft focus, each similar in appearance with the same bun, meat, and cheese layers. The overall setting suggests a warm, comforting meal. Photo taken with an iphone --ar 2:3 --v 7

Step 1: Season and Flour the Beef for a Perfect Crust

Start by generously seasoning your 2 ¼ lb beef chuck roast with kosher salt and freshly ground black pepper on all sides. This seasoning really brings out the meat’s natural flavors. Next, lightly coat the roast with 2 tablespoons of all-purpose flour. This step helps the roast develop a beautiful crust while searing, locking in those juices that make every bite tender and flavorful.

Step 2: Sear the Roast for Deep Flavor

If your slow cooker insert has a sear function, you’re in luck—preheat it now. Otherwise, heat a heavy pan like a cast iron skillet over medium-high heat on the stovetop. Add 1 tablespoon of extra-virgin olive oil, then sear the roast for about 3-4 minutes on each side until it’s evenly browned all around. You’ll notice a rich, savory aroma—that’s when you know you’re on the right track! Set the roast aside once seared.

Step 3: Layer Flavors in the Slow Cooker

In the slow cooker insert, combine 4 cups of rich beef broth made from Zoup! Good, Really Good® Culinary Concentrate™️ Beef Base with Bone Broth, 3 tablespoons Worcestershire sauce, 2 medium yellow onions (halved and sliced), 3 sprigs of thyme, and 1 bay leaf. Nestle your seared beef into this savory mixture. The onions and herbs will gently infuse the meat as it slow cooks—trust me, this aroma is absolutely mouthwatering.

Step 4: Slow Cook to Tender Perfection

Cover and cook on HIGH for 4 hours or LOW for 8 hours. The longer, slower cook results in meat that’s so tender it easily shreds with a fork—and that’s the true magic of this recipe. When you poke the meat, it should feel soft, and the broth will be rich and fragrant.

Step 5: Slice the Beef Thinly and Prepare the Juices

Carefully transfer the roast to a cutting board and slice it into ¼-inch thick pieces. Meanwhile, strain the broth to catch any bay leaf and thyme sprigs, discarding them. Return the onions and sliced beef to the slow cooker, adding just enough strained broth to keep everything moist. Keep the reserved au jus warm in a saucepan, seasoning to taste with salt and pepper if needed. This broth will be your golden dipping companion.

Step 6: Toast the Rolls and Whisk the Horseradish Mayo

Toast 6 French sandwich rolls until golden and crispy on the outside. While they toast, whisk together 3 tablespoons mayonnaise with 3 teaspoons horseradish for a creamy, tangy spread that cuts through the richness of the beef. This simple spread adds a delightful kick to each bite.

Step 7: Assemble and Melt for the Ultimate Sandwich

Spread a thin layer of the horseradish mayo on each toasted roll. Layer on the sliced beef and some of the sweet onions from the slow cooker, then top each sandwich with a slice of provolone cheese. Place the assembled sandwiches under a broiler for about 1-2 minutes, just until the cheese melts and bubbles invitingly. If you don’t have a broiler, a hot oven at 400°F for 3-5 minutes works great too.

Step 8: Serve with Warm Au Jus and Enjoy

Serve your Slow Cooker French Dip Sandwiches immediately alongside the warm reserved au jus. Dip generously, savor the melty cheese, tender beef, and tangy spread all together—and get ready for a meal that feels like a comforting hug on a plate.

Top Tip

Mastering your Slow Cooker French Dip Sandwiches Recipe is easier with a few insider tricks that bring out the best flavors and textures every time. These tips will help you get that perfect tender beef, melty cheese, and savory jus that makes this sandwich irresistible.

Sear the Beef Well: I always make sure to get a good brown crust on the chuck roast before slow cooking. It locks in flavor and gives that rich, savory depth you want in every bite.
Don’t Skip Straining the Jus: Removing the bay leaf and thyme after cooking keeps your broth smooth and aromatic, letting the beef and onion flavors shine perfectly without being overpowering.
Toast Your Rolls Just Right: Toasting until golden but not too crispy ensures the bread holds up well to juicy beef and soaking in the au jus without turning soggy.
Broil Cheese Quickly: Melting the provolone under a hot broiler for just 1-2 minutes makes the cheese wonderfully bubbly without drying out the meat underneath.

How to Serve Slow Cooker French Dip Sandwiches Recipe

A black cooking pot holds a thick piece of browned meat placed in the center, surrounded by a layer of white onion slices that fill the rest of the pot. The pot sits on a wooden surface with fresh green herbs placed near the top edge. Around the pot are various cooking items including a white pan with bread rolls, a small wooden bowl of coarse salt, a root vegetable, a container with a dark sauce, and a beige cloth with a purple stripe. The whole scene has a rustic, homey feel with natural tones and textures. photo taken with an iphone --ar 2:3 --v 7

Garnishes

Brighten up your sandwiches with a sprinkle of fresh parsley or a few rings of pickled jalapeños for a little zing. A side of tangy pickles or crisp dill pickle spears adds a lovely contrast that complements the rich beef and creamy horseradish mayo perfectly.

Side Dishes

Classic sides like crispy fries or sweet potato wedges pair beautifully with these sandwiches. For a lighter option, try a simple green salad with a citrus vinaigrette or roasted seasonal vegetables. Creamy coleslaw is also a great way to add some crunch and balance the savory flavors.

Make Ahead and Storage

Storing Leftovers

Keep leftover sliced beef and onions together in an airtight container and refrigerate for up to 3 days. Store the reserved au jus separately to maintain its fresh flavor and avoid soggy sandwiches later.

Freezing

You can freeze any leftover au jus in a freezer-safe container or bag for up to 3 months. Freeze sliced beef and onions separately if you want to preserve texture. Just thaw overnight in the fridge before reheating.

Reheating

Warm the beef and onions gently in the reserved au jus on the stovetop over low heat to keep them moist. Toast fresh rolls and assemble sandwiches, then melt cheese under the broiler or in a 400°F oven for 3-5 minutes before serving.

Frequently Asked Questions:

Can I use a different cut of beef for this recipe?

While beef chuck roast works best for tender, flavorful results, you can also use brisket or bottom round roast. Just make sure to adjust cooking times if needed to ensure the beef becomes tender enough to shred.

How do I make the horseradish mayo less spicy?

If you prefer a milder spread, reduce the horseradish to 1-2 teaspoons or add a bit more mayonnaise to balance the heat to your liking.

Can I prepare this recipe without a broiler?

Absolutely! If you don’t have a broiler, simply melt the cheese in a hot oven set to 400°F for about 3-5 minutes until bubbly and golden.

What’s the best way to keep the sandwich from getting soggy?

To avoid soggy sandwiches, toast the rolls well and spread the horseradish mayo thinly. Serve immediately with the au jus on the side for dipping rather than soaking the bread ahead of time.
