Needed Ingredients For French Dip Sandwich

Gather these simple ingredients to create your own amazing slow cooker French dip sandwich:

  • 2-3 pound beef chuck roast or rump roast, trimmed of excess fat
  • 3 cups low sodium beef broth
  • ¼ cup Worcestershire sauce
  • 2 tablespoons extra virgin olive oil
  • 2 yellow onions, quartered and thinly sliced
  • 3 cloves of garlic, minced
  • 1 bay leaf
  • Salt and pepper, to taste
  • 4-6 sturdy rolls, such as hoagie or sub rolls
  • 8-12 slices cheese (provolone, Swiss, Havarti, or Monterey Jack)

Notes & Substitutions

  • Beef: A chuck roast works wonderfully for its marbling and tenderness. Rump or sirloin roasts are leaner options, but ensure you cook them until fork-tender.
  • Broth: Always opt for low-sodium beef broth. This lets you control the final seasoning without making the au jus too salty.
  • Worcestershire: This ingredient is crucial for adding a layer of umami and depth to the overall flavor profile. Don’t skip it!
  • Onions: Taking the time to caramelize the onions slightly before slow cooking adds an incredible sweetness and depth.
  • Rolls: Choose sturdy, crusty rolls like a French baguette or hoagie roll. Soft rolls can become soggy too quickly when dipped.
  • Cheese: Provolone cheese is classic, but Swiss or Havarti also melt beautifully and complement the beef.

Equipment

You don’t need many special tools for this delightful recipe.

  • Slow cooker (6-quart recommended): Essential for tender, slow-cooked beef.
  • Large cast-iron skillet or Dutch oven: Perfect for searing the beef and sautéing onions.
  • Fine-mesh strainer: Crucial for creating a smooth, clear au jus for your French dip.
  • Cutting board and sharp knife: For prepping ingredients and slicing the cooked beef.

Follow these easy steps for a truly delicious slow cooker French dip sandwich. This recipe will guide you to perfect, fork-tender beef and a rich au jus.

Prepare the Ingredients

Liberally season your beef roast with salt and pepper on all sides. In a large glass measuring cup, combine the beef broth and Worcestershire sauce, then set it aside.

Sear the Beef Roast

Heat the extra virgin olive oil in a large cast-iron skillet or Dutch oven over medium-high heat. Add the seasoned beef roast to the hot oil. Sear the meat on all sides until a beautiful brown crust forms. This crucial step locks in flavor. Once seared, transfer the beef into your slow cooker.

Sauté Onions and Garlic

Reduce the heat to medium in the same skillet. Add the thinly sliced onions, along with more oil if needed, and cook for about 5 minutes until they begin to soften. Stir in the minced garlic and cook for an additional 1-2 minutes until fragrant.

Deglaze the Pan

Pour a couple of tablespoons of the reserved beef broth mixture into the skillet with the onions and garlic. Using a wooden spoon, scrape up all the flavorful browned bits from the bottom of the pan. This step is called deglazing and adds immense depth to your au jus.

For Slow Cooker

  • Transfer the onion mixture and all accumulated juices into the slow cooker, joining the seared beef. Pour in the remaining beef broth mixture and add the bay leaf. Cook on high for 3-4 hours or on low for 5-6 hours, until the beef is incredibly tender and easily shreds with a fork.
  • Slow cooking helps tenderize tougher cuts of beef, breaking down connective tissues and resulting in succulent, fall-apart meat. Carefully remove the cooked beef to a cutting board.
  • Thinly slice it against the grain or shred it into delicious pieces, then set it aside. Place a fine-mesh strainer over a large bowl.
  • Carefully pour all the cooking liquid from the slow cooker through the strainer into the bowl; this is your flavorful au jus. Discard the bay leaf and reserve the strained onions.
  • Return the sliced or shredded beef and strained onions to the slow cooker. Pour a little au jus over the meat to moisten it and season to taste with salt and pepper.
  • Reserve the remaining au jus in a separate serving bowl for dipping. If you desire more au jus, stir in a little extra beef broth to extend it.
  • To assemble your slow cooker French dip sandwich, toast your rolls slightly. Fill them generously with the moist beef and onions. Top with your chosen cheese slices.
  • Melt the cheese by placing the sandwiches in a 375°F oven for a few minutes or briefly under the broiler until bubbly and golden. Serve immediately with the warm au jus on the side for dipping.

For Instant Pot (Brief)

  • Use the Instant Pot’s sauté mode to sear the beef and sauté onions and garlic as described above, deglazing the pot with broth.
  • After searing, add the beef, onion mixture, remaining broth, and bay leaf to the Instant Pot.
  • Cook on high pressure for 60 minutes, followed by a 20-minute natural pressure release. Follow the same steps for shredding/slicing the beef, straining the au jus, and assembling the sandwiches as detailed in the slow cooker instructions.
  • The Instant Pot offers a faster way to achieve equally tender results for your French dip sandwiches.

Pro Tips & Troubleshooting

Achieve the best slow cooker French dip sandwich every time with these helpful tips.

  • Searing: Do not skip searing the beef! This step creates a rich, caramelized crust, building the foundation of flavor for your au jus and beef.
  • Deglazing: Make sure to scrape up all the browned bits from the bottom of the pan after sautéing onions. These “fonds” are packed with savory taste.
  • Meat Texture: Always slice the beef against the grain for the most tender, melt-in-your-mouth experience. This shortens the muscle fibers.
  • Au Jus: Taste your au jus before serving. If it tastes bland, adjust the seasoning with a pinch more salt, pepper, or a dash of Worcestershire.
  • Roll Choice: Opt for sturdy, crusty rolls that can hold up to being dipped in au jus. Baguettes or hoagie rolls are ideal choices.
  • Serving: Keep your au jus warm in a small saucepan or a slow cooker on the “keep warm” setting until you are ready to serve.

Serving, Storage, & Variations

These versatile slow cooker French dip sandwiches are perfect for many occasions.

Serving Suggestions

  • Serve your savory French dip with a side of crispy golden fries for a classic diner experience.
  • Pair the rich sandwich with a light green salad tossed with a vinaigrette to balance the meal.
  • Offer potato chips or creamy coleslaw as simple, satisfying accompaniments.

Storage & Reheating

  • Store leftover cooked beef and onions separately from the au jus for best results. Place them in airtight containers.
  • Refrigerate for up to 3 days.
  • Gently reheat the beef and au jus on the stovetop over low heat, or use a microwave. Avoid boiling the au jus to preserve its flavor.

Flavor Variations

  • Add sliced mushrooms to the slow cooker along with the onions for an earthy flavor.
  • Include bell peppers, thinly sliced, during the last hour of cooking for extra sweetness and color.
  • Experiment with different cheese varieties like Gruyere or Monterey Jack for unique twists.
  • For a subtle kick, add a touch of red pepper flakes to the slow cooker liquid.
