Introduction

French dip sandwiches are one of those “everyone’s happy” meals: juicy, tender beef piled into warm toasted rolls, served with a deeply savory dipping broth (au jus) that makes every bite taste like comfort food from a classic deli. This slow cooker version keeps it unbelievably easy. You place the roast in the crockpot, pour in a few flavorful liquids, and let time do all the work.

The result is beef so tender it practically falls apart, plus a rich, dark jus that tastes like you simmered it for hours—because you did, just without standing at the stove. Beer adds depth (and helps tenderize), French onion soup brings built-in seasoning and sweetness, and beef broth rounds it all out into that signature dip-friendly gravy-like broth.

This recipe is perfect for game day, casual parties, busy weeknights, and even meal prep. You can cook the beef ahead, shred it, store it in the broth, and reheat whenever you’re ready. Toast the rolls right before serving so they stay crisp on the outside but still soak up the jus when dipped.

• Built-in au jus—no extra sauce-making required

• Perfect for feeding a crowd and great for leftovers

Equipment

• 5- to 6-quart slow cooker

• Tongs or large fork (for removing the roast)

• Cutting board

• Two forks (for shredding) or a knife (for slicing)

• Baking sheet (for toasting rolls)

• Fine-mesh strainer (optional, for a clearer jus)

Ingredients

Main Ingredients

• 4 lb boneless beef round rump roast or boneless beef chuck pot roast, trimmed

• 1 (12-oz) can or bottle beer

• 1 (10.5-oz) can condensed French onion soup

• 1 (14.5-oz) can low-sodium beef broth

• 8 French rolls

• 2 tablespoons butter (for toasting rolls)

Optional Ingredients

• Chopped fresh parsley (for garnish)

• Provolone or Swiss cheese slices (for a melty version)

• Sliced onions (extra, for more onion flavor)

• Pepperoncini (for a tangy bite)

Instructions

Step 1: Preparation

Place the trimmed roast into a 5–6 quart slow cooker. Pour in the beer, French onion soup, and beef broth. Gently move the roast so it sits mostly submerged.

Cover and cook:

• Low: 10–12 hours

• High: 5–6 hours

The roast is ready when it pulls apart easily with a fork.

Step 2: Mixing / Assembling

Near serving time, preheat the oven to 400°F (200°C).

Split the French rolls (don’t cut all the way through if you like a “hinge”). Butter the insides. Place on a baking sheet and toast until golden, about 5 minutes.

Step 3: Cooking / Finishing the Beef

Remove the roast from the slow cooker and shred with two forks (or slice thinly if you prefer). If you like a cleaner dipping broth, strain the cooking liquid through a fine-mesh strainer. Taste the jus and adjust if needed (pepper is great here).

Return the shredded beef to the slow cooker for a few minutes so it stays warm and juicy.

Step 4: Serving

Pile beef into toasted rolls and sprinkle with parsley if using. Serve with warm jus for dipping.

Tips & Notes

• Tip for best texture: Chuck roast tends to shred more luxuriously; round roast is leaner and slightly firmer—both work.

• Flavor enhancement tip: Add a splash of Worcestershire or a pinch of black pepper to the broth for deeper savory notes.

• Common mistake to avoid: Don’t skip toasting the rolls—untoasted bread can get soggy too fast when dipped.

• Jus tip: If it tastes too salty, add a little water or extra low-sodium broth.

Variations

Ingredient Variations

• Cheesy French dip: Add provolone or Swiss and broil 1 minute to melt

• Spicy twist: Add pepperoncini, a spoon of their brine, or a pinch of chili flakes

• Herby version: Add thyme or rosemary while cooking (remove stems before serving)

Dietary Variations

• No alcohol: Replace beer with more beef broth or a splash of apple cider + broth

• Lower sodium: Use unsalted broth and low-sodium soup if available; dilute jus if needed

Storage & Make-Ahead

• How to store leftovers: Keep beef submerged in the jus in an airtight container

• Refrigerator duration: Up to 4 days

• Freezer instructions: Freeze beef with some jus for up to 2 months

• Make-ahead tips: Cook the roast a day early, shred, refrigerate in jus, then reheat gently in the slow cooker or on the stove.

Serving Suggestions

• Side dishes: fries, roasted potatoes, coleslaw, or a simple green salad

• Salads: chopped salad with vinaigrette (cuts through richness)

• Bread or grains: serve open-faced over toasted bread with extra jus like a “beef dip toast”

• Beverage pairings: iced tea, sparkling water, or a light beer

Time Breakdown
