French Dip Grilled Cheese
There’s nothing quite like the comforting embrace of a truly exceptional French Dip Grilled Cheese. I remember the first time I perfected that golden, crispy exterior combined with juicy roast beef and melting cheese. It instantly became a new favorite, right up there with my beloved air fryer chicken sandwich.
Growing up, grilled cheese was a simple comfort, but adding the rich flavors of a French dip elevates it to something special. My grandma always said the best meals were those that brought people together, and this sandwich certainly does.
This recipe offers hearty satisfaction with surprisingly low stress, making it perfect for busy weeknights. My secret? Always use good quality sourdough; it makes all the difference!
What You Need to Make This Recipe
To create this delightful French Dip Grilled Cheese, we gather savory roast beef, rich beef broth, and melty provolone and Swiss cheeses. It’s a comforting blend, just like my marry me steak sandwich. The full list awaits in the recipe card below!
How to Make French Dip Grilled Cheese
Making this amazing French Dip Grilled Cheese starts with preparing a rich au jus and perfectly caramelized onions. Then, I layer the roast beef and cheeses onto sourdough, similar to my smoked gouda apple grilled cheese. Finally, cook until golden and serve them warm, ready for a delicious dip!
Pro Tips for Making This French Dip Grilled Cheese
When I make my French Dip Grilled Cheese, I’ve picked up a few tricks over the years that really elevate the experience. For that perfect golden crust, I always butter the outside of the sourdough generously, edge to edge. It creates an unbeatable crunch!
For the Best Caramelized Onions
My top tip for truly deep, flavorful caramelized onions is patience. Don’t rush them! Cook them slowly over medium-low heat until they’re a rich, golden brown. This brings out their natural sweetness, making every bite of your sandwich extra special.
My Secret Trick: I always add a splash of beef broth to my caramelized onions in the last few minutes of cooking. It deglazes the pan, picking up all those delicious browned bits, and adds an incredible depth of flavor that takes the au jus to the next level.
How to Store French Dip Grilled Cheese
If by some miracle you have leftover French Dip Grilled Cheese, proper storage is key to enjoying it later. I always separate the sandwiches from any leftover au jus. Store the sandwiches in an airtight container in the fridge for up to 2-3 days. The au jus can be stored separately in its own container.
When reheating, I find the best way to bring your French Dip Grilled Cheese back to life is to gently warm it in a pan on the stovetop over medium-low heat. This helps the bread crisp up again, rather than becoming soggy. You can also warm the au jus separately on the stove. Reheating slowly really helps preserve that wonderful texture and flavor!
Nutritional Benefits
This French Dip Grilled Cheese delivers satisfying protein from the roast beef and calcium from the cheeses, making it a hearty, family-friendly meal. It’s a comforting dish that offers good fuel!
FAQs
Can I prepare the au jus ahead of time for this French Dip Grilled Cheese?
Absolutely! I often make the au jus a day or two in advance. It actually allows the flavors to meld even further, making your dipping experience more robust. Store it in an airtight container in the refrigerator and gently reheat before serving your French Dip Grilled Cheese.
What’s the best type of roast beef to use for my French Dip Grilled Cheese?
For the most tender and flavorful French Dip Grilled Cheese, I recommend using thinly sliced deli roast beef. Look for a good quality brand that isn’t too fatty. Some delis even offer freshly sliced roast beef, which can make a wonderful difference in the final taste and texture of your sandwich.
Can I use different cheeses in my French Dip Grilled Cheese?
Of course! While I love the classic provolone and Swiss blend, feel free to experiment. Muenster or even a sharp white cheddar could be delicious additions. Just ensure they are good melting cheeses to get that gooey, comforting center in your French Dip Grilled Cheese. Enjoy playing with flavors!
How do I prevent my French Dip Grilled Cheese from getting soggy?
To keep your French Dip Grilled Cheese from getting soggy, toast the bread lightly before assembling, especially if you’re using very juicy ingredients. Also, don’t over-dip in the au jus; a quick dunk is all you need. Serving immediately after cooking is always best to maintain that perfect crispness.

Ultimate French Dip Grilled Cheese
Ingredients
Equipment
Method
- Heat olive oil in a small saucepan over medium heat. Add the thinly sliced yellow onion and cook, stirring occasionally, for 8-10 minutes until softened and beginning to caramelize.
- Add minced garlic and cook for another minute until fragrant.
- Pour in the beef broth, Worcestershire sauce, Dijon mustard, dried thyme, black pepper, and optional red pepper flakes. Bring to a simmer, then reduce heat to low, cover, and let it gently simmer for at least 15 minutes while you prepare the sandwiches. This allows the flavors to meld.
- While the au jus is simmering, separate out about 2 tablespoons of the caramelized onions from the saucepan for the sandwiches; set aside. Keep the remaining au jus simmering.
- Butter one side of each slice of sourdough bread generously with softened butter.
- Lay two slices of bread, butter-side down, on a clean surface.
- On each of these slices, layer one slice of provolone cheese, half of the roast beef, the reserved caramelized onions, another slice of provolone, and optionally, a slice of Swiss cheese.
- Top with the remaining two slices of bread, butter-side up.
- Preheat a large skillet or griddle over medium-low heat.
- Carefully place the assembled sandwiches into the preheated skillet. Cook for 5-7 minutes per side, or until the bread is golden brown and crispy, and the cheese is thoroughly melted and gooey. You may need to adjust the heat to prevent burning while ensuring the cheese melts.
- Once cooked, remove the sandwiches from the skillet and let them rest on a cutting board for a minute.
- Slice each sandwich in half diagonally.
- Ladle the hot au jus into small individual dipping bowls.
- Serve the French Dip Grilled Cheese immediately with the au jus for dipping.
Notes
The quality of your roast beef and bread makes a big difference in this recipe!
