It’s the kind of meal that works perfectly for a cozy evening dinner, a satisfying weekend lunch, or even a quick comfort meal after a long day.

The inspiration behind this recipe comes from the traditional French dip sandwich, famous for its tender beef served with a flavorful dipping broth known as au jus. By combining that concept with the golden crunch and cheesy interior of grilled cheese, this recipe delivers the best of both worlds. Every bite offers buttery toasted bread, melted cheese, juicy roast beef, and a warm savory dipping sauce that brings the whole sandwich together.

What Is a French Dip Grilled Cheese?

A French Dip Grilled Cheese is a hybrid sandwich that merges the flavors of a classic French dip sandwich with a grilled cheese.

Traditionally, a French dip sandwich features sliced roast beef served on bread with a savory broth for dipping. In this version, the beef is layered with melted cheese between slices of buttery toasted bread, creating a crispy grilled sandwich that can still be dipped into warm au jus.

The result is a comforting, indulgent sandwich with bold flavors and satisfying textures.

How to Make French Dip Grilled Cheese

Step 1: Prepare the Au Jus

In a small saucepan, combine:

• 2 cups (480 ml) beef broth

• 1 teaspoon Worcestershire sauce

• ½ teaspoon garlic powder

• ¼ teaspoon black pepper

Bring the mixture to a gentle simmer over medium heat.

In a small bowl, mix:

• 4 tablespoons softened butter (56 g)

Step 4: Cook the Sandwiches

Heat a skillet or griddle over medium heat.

Place the sandwiches into the skillet and cook for 3–4 minutes until the bottom is golden brown.

Flip carefully and cook another 3–4 minutes until the cheese melts and the bread becomes crispy.

If the bread browns too quickly, reduce heat slightly to allow the cheese to melt fully.

Step 5: Serve

Remove sandwiches from the skillet and let them rest for about 1 minute.

Slice each sandwich in half and serve with warm au jus in small bowls for dipping.

Tips for the Best French Dip Grilled Cheese

Use Quality Bread

Thicker bread like sourdough or bakery sandwich bread holds up best when dipped into the broth.

Choose Melty Cheese

Provolone works beautifully because it melts smoothly and complements the beef flavor. You can also combine it with mozzarella for extra stretch.

Warm the Roast Beef

If your roast beef is cold from the refrigerator, warm it briefly in the skillet before assembling the sandwich. This helps the cheese melt faster.

Don’t Rush the Toasting

Cook the sandwich over medium heat instead of high heat to achieve a golden crust without burning the bread.

Delicious Variations

Caramelized Onion French Dip Grilled Cheese

Add ½ cup caramelized onions (75 g) to each sandwich for sweetness and deeper flavor.

Garlic Butter Version

Add ½ teaspoon garlic powder (2 g) and ½ teaspoon dried parsley (1 g) to the butter mixture.

Extra Cheesy Sandwich

Combine 4 slices provolone (112 g) with 4 slices mozzarella (112 g) for even more meltiness.

Frequently Asked Questions

1. What type of bread works best for French Dip Grilled Cheese?

The best bread for this sandwich is thick, sturdy bread that can hold up to the filling and the dipping broth. Sourdough is one of the most popular choices because it has a firm crust and a slightly tangy flavor that complements the rich roast beef and melted cheese. Texas toast is another excellent option because it is thick and buttery, creating a perfectly crisp exterior when grilled.

Standard sandwich bread can work if that is what you have available, but thicker slices tend to provide a better texture. A good French Dip Grilled Cheese should have a crunchy outside and a soft, melty interior. Bread that is too thin may become soggy when dipped into the au jus.

Another great option is artisan country bread. These breads usually have a strong structure that holds the filling well while still becoming beautifully golden when toasted. If you enjoy a rustic flavor, a crusty loaf sliced thick can elevate the sandwich even further.

The key is choosing bread that balances crispness and durability so that the sandwich remains satisfying from the first bite to the last.

---

2. Can I use a different cheese instead of provolone?

Yes, several cheeses work well in a French Dip Grilled Cheese, depending on your flavor preference. Provolone is a classic choice because it melts smoothly and has a mild flavor that pairs perfectly with roast beef. However, there are plenty of other options you can try.

Mozzarella is an excellent substitute if you want a stretchy, gooey texture. It melts beautifully and provides a creamy mouthfeel. Swiss cheese is another great option because it adds a slightly nutty flavor that complements the savory beef.

White cheddar can also be used if you prefer a sharper cheese flavor. It melts well and adds a little extra richness to the sandwich. Some people even enjoy combining cheeses for the best flavor and texture.

For example, using half provolone and half mozzarella can give you both flavor and stretch. The key is choosing cheeses that melt well so that the sandwich becomes perfectly gooey when grilled.

---

3. How do I keep the sandwich crispy instead of soggy?

Keeping the sandwich crispy comes down to a few simple techniques. First, make sure to spread butter evenly across the outside of the bread. This helps the bread toast evenly and creates a golden crust that stays crisp.

Cooking the sandwich over medium heat is also important. If the heat is too high, the bread may brown too quickly before the cheese melts. A slower cooking process allows the sandwich to toast evenly while the inside becomes perfectly melted.

Another helpful tip is to avoid adding too much moisture inside the sandwich. Roast beef can sometimes release juices when heated, so lightly warming the meat before assembling the sandwich can help control excess moisture.

Finally, serve the sandwich immediately after cooking. Grilled cheese is always best when fresh off the skillet because the bread maintains its crisp texture while the cheese remains melted and creamy.

---

4. Can French Dip Grilled Cheese be made ahead of time?

While this sandwich is best enjoyed fresh, you can prepare some components ahead of time to make cooking faster later. For example, the au jus dipping sauce can be made in advance and stored in the refrigerator for up to three days. When you are ready to serve the sandwiches, simply reheat the sauce gently on the stovetop.

You can also slice the cheese and portion the roast beef ahead of time. Having all the ingredients prepared makes assembly much quicker when it’s time to cook.

However, it is not recommended to fully assemble and store the sandwiches before cooking because the bread can absorb moisture from the filling. This may prevent the bread from crisping properly in the skillet.

If you need to prepare the sandwiches for later, cook them first and store them in the refrigerator for up to one day. Reheat them in a skillet or oven to restore some of the crisp texture. Avoid microwaving because it can make the bread soft.

For the best flavor and texture, freshly grilled sandwiches are always the ideal choice.
