Ingredients Breakdown

Sourdough Bread

Thick slices of sourdough create the perfect foundation for this sandwich. The sturdy texture crisps beautifully while staying chewy inside, making it ideal for dipping into the warm au jus without falling apart.

Roast Beef

Thinly sliced deli roast beef or leftover homemade roast beef both work wonderfully. The beef adds savory richness and creates the classic French dip flavor everyone loves.

Provolone Cheese

Provolone melts smoothly and provides a mild, creamy flavor that pairs perfectly with beef. It creates the gooey texture that makes grilled cheese so satisfying.

Swiss Cheese

Swiss cheese contributes a slightly nutty flavor while melting beautifully alongside the provolone. Using both cheeses creates a more complex and delicious sandwich.

Butter

Softened butter spread generously on the outside of each bread slice ensures an evenly golden, crispy crust. It also adds rich flavor and helps the bread toast perfectly.

Garlic Powder

A light sprinkle of garlic powder enhances the buttery crust without overpowering the sandwich. It adds subtle depth and aroma.

Onion Powder

Onion powder complements the roast beef and blends beautifully with the cheese, giving the sandwich extra savory flavor.

Black Pepper

Freshly ground black pepper adds gentle warmth and balances the richness of the cheese and butter.

Beef Broth

A high-quality beef broth forms the base of the au jus. Rich broth creates the signature dipping sauce that defines a French dip sandwich.

Worcestershire Sauce

Just a splash brings bold umami flavor to the au jus, making it taste like it simmered for hours.

Fresh Thyme

Fresh thyme adds a subtle herbal note that brightens the dipping sauce and pairs naturally with beef.

Parsley (Optional)

Fresh chopped parsley adds color and a touch of freshness before serving.

How to Make

Start by preparing the au jus. In a small saucepan, combine beef broth, Worcestershire sauce, fresh thyme, a pinch of garlic powder, onion powder, and black pepper. Bring the mixture to a gentle simmer and let it cook for about 10 minutes so the flavors blend together. Keep it warm while preparing the sandwiches.

Next, butter one side of every slice of sourdough bread. Place one slice butter-side down in a skillet over medium-low heat.

Layer provolone cheese first, followed by the roast beef. Spread the beef evenly across the bread to ensure every bite is full of flavor. Add Swiss cheese over the beef before topping with the second slice of bread, butter-side facing outward.

Cook slowly over medium-low heat. This allows the bread to become golden and crispy while giving the cheese enough time to melt completely. Press gently with a spatula for even browning.

Flip carefully once the bottom is deeply golden. Cook the second side until equally crisp and the cheese is fully melted.

If needed, reduce the heat slightly to prevent burning while the cheese finishes melting.

Transfer the sandwich to a cutting board and let it rest for one minute before slicing. This helps keep the melted cheese inside the sandwich.

Pour the warm au jus into small serving bowls and garnish with chopped parsley if desired.

Serve immediately while everything is hot and crispy, allowing each bite to be dipped generously into the flavorful au jus.

Common Mistakes to Avoid

• Using bread that’s too thin
• Cooking over high heat, which burns the bread before the cheese melts
• Overfilling the sandwich with beef
• Skipping the resting time before slicing
• Using cold cheese straight from the refrigerator
• Forgetting to season the au jus
• Not buttering the bread evenly
• Serving the au jus lukewarm instead of hot

Storage/Reheating

Store leftover sandwiches in an airtight container in the refrigerator for up to 3 days. Keep the au jus separately. Reheat the sandwich in a skillet or oven until crispy and heated through. Warm the au jus on the stovetop or in the microwave before serving. Avoid microwaving the sandwich alone if possible, as it may become soggy.

Variations and Customizations

One of the best things about French Dip Grilled Cheese is how versatile it is. You can easily customize it based on what you have available or to match your personal taste.

Try replacing sourdough with Texas toast, artisan country bread, rye bread, or ciabatta for a different texture. Each bread creates its own unique crust while still holding up well to dipping.

Experiment with different cheese combinations. Mozzarella creates extra stretch, while white cheddar adds a sharper bite. Havarti offers incredible creaminess, and Gruyère provides a rich, nutty flavor that complements roast beef beautifully.

Instead of deli roast beef, use leftover pot roast, slow-cooked shredded beef, smoked brisket, or even thinly sliced steak. Each option creates a delicious variation with slightly different textures.

For extra flavor, caramelized onions are an outstanding addition. Mushrooms sautéed with butter and garlic also pair wonderfully with the beef.

A light spread of Dijon mustard inside the sandwich adds gentle tanginess without overpowering the other ingredients. Horseradish sauce offers a bold kick for those who enjoy stronger flavors.

Fresh herbs like rosemary or thyme can be added to the butter before grilling to create a more aromatic crust.

If you’re looking to lighten the recipe, use reduced-fat cheese and less butter while maintaining excellent flavor.

For extra crunch, sprinkle grated Parmesan onto the buttered bread before grilling. It creates an incredibly crispy, cheesy crust.

Spice lovers can add sliced jalapeños, crushed red pepper flakes, or pepper jack cheese for additional heat.

No matter which variation you choose, always serve the sandwich with warm au jus. It’s the finishing touch that transforms grilled cheese into an unforgettable comfort meal.
