- Texas toast or thick-sliced white bread: the thick cut holds up to the juicy fillings and gets wonderfully crisp and golden.

How to Make It
Preheat and Prepare Your Tools:
Get your oven heating to 400°F and line a baking sheet with parchment paper or foil. This simple step saves you from a messy cleanup later, which is always a win in my book.
Caramelize the Onions:
Melt two tablespoons of butter in a large skillet over medium heat and add your sliced onions. Cook them slowly, stirring now and then, until they turn soft and a deep golden brown. This slow cooking unlocks their natural sugars and builds a flavor foundation you can’t rush.
Toast the Texas Toast:
While the onions work their magic, spread the remaining butter on both sides of each bread slice. Arrange them on your prepared baking sheet and bake, flipping halfway through, until they’re golden and crisp. This double-sided toasting ensures every bite has that perfect buttery crunch.
Simmer the Au Jus:
In a medium saucepan, combine the beef broth, Worcestershire sauce, garlic powder, onion powder, and a pinch of salt and pepper. Bring it to a simmer and let it cook gently for about ten minutes. This brief simmer allows all those savory flavors to meld together into a rich, dippable broth.
Assemble the Sandwiches:
Place four slices of your toasted bread on a clean surface. Layer each one generously with roast beef, a pile of those caramelized onions, and a slice of provolone cheese. Top each pile with the remaining toast to create your hefty Texas Toast French Dips.
Melt the Cheese:
Place the assembled sandwiches back on the baking sheet and slide them into the hot oven. Bake for just about five minutes, or until the cheese is fully melted and bubbly. This quick bake warms everything through and makes the cheese perfectly gooey.
Slice and Serve Immediately:
Use a sharp knife to slice each sandwich in half diagonally. Serve them right away with individual bowls of that hot, flavorful au jus for dipping. The contrast of the crisp toast with the warm, juicy interior is what makes these sandwiches so special.

You Must Know
- Quality beef broth is the soul of your au jus
- Take your time with the onions for the best flavor
- The toast needs to be sturdy to hold up to the dip
- I always make extra au jus because people will want it
Storage Tips
If you somehow have leftovers, store the sandwiches and the au jus separately in airtight containers in the fridge for up to three days. To reheat, warm the sandwiches in a 350°F oven for about ten minutes to keep the toast crisp, and gently warm the au jus in a small saucepan over low heat. I don’t recommend the microwave for the sandwiches as it’ll turn the toast soggy, but the oven method brings them back to life beautifully.
Ingredient Substitutions
If you can’t find Texas toast, any good-quality thick-sliced artisan bread will work just fine. Swap the provolone for Swiss, mozzarella, or even a sharp cheddar if you prefer. For the au jus, a splash of red wine or a teaspoon of soy sauce can add extra depth if you’re feeling adventurous. If you need a dairy-free version, use your favorite plant-based butter and a good melting vegan cheese alternative.
Serving Suggestions
I love serving these Texas Toast French Dips with a big pile of crispy seasoned french fries or crunchy dill pickle spears on the side for that classic diner feel. A simple side salad with a tangy vinaigrette helps cut through the richness, or you could go for crispy onion rings or sweet potato fries. It’s the perfect casual meal for feeding a hungry group with minimal fuss.
Cultural Context
The French dip sandwich itself has roots in early 20th century Los Angeles, but this version with Texas toast is a distinctly American heartland twist. Texas toast is all about abundance and comfort—thick slices meant to hold up to generous toppings, born from the same spirit as other oversized favorites. By combining it with the classic French dip, you get a hybrid that celebrates big flavors and satisfying textures, perfect for casual gatherings and family suppers across the country. It’s a testament to how regional food traditions can blend into something new and wonderful.

Pro Tips
- Warm your deli roast beef in the au jus for a minute for extra tenderness
- Let the au jus simmer a bit longer if you want a more concentrated flavor
- Don’t overcrowd the baking sheet when toasting the bread for even browning
- I always use a rimmed baking sheet to catch any buttery drips
Frequently Asked Questions
This recipe is designed for thick, pre-sliced Texas toast, which holds up to the hearty fillings and dipping. If you can’t find it, use thick-sliced white bread like sourdough or French bread. The key is a sturdy, thick slice that won’t get soggy under the juicy roast beef and rich au jus.
You can prepare the au jus with caramelized onions ahead of time and reheat it when ready to serve. For best results, assemble and broil the sandwiches just before eating so the toast stays crispy and the cheese is perfectly melted. Keep the sliced roast beef and prepared au jus separate in the fridge until you’re ready to assemble.
Provolone melts beautifully and has a mild flavor that pairs perfectly with the roast beef. Excellent substitutes include Swiss cheese, mozzarella, or a mild white cheddar. For a sharper flavor, you could use a thin slice of pepper jack, but avoid very hard cheeses that don’t melt as easily for this hot sandwich.
The sandwiches are ready when the cheese is completely melted and bubbly, and the edges of the Texas toast are a light golden brown. This usually takes 2-4 minutes under the broiler, but watch them closely to prevent burning. The au jus should be hot and simmering when served.
Keep it simple with classic American sides. A crisp dill pickle spear, potato chips, or a tangy coleslaw are perfect. For a heartier meal, serve with crispy steak fries, sweet potato fries, or a simple side salad. The rich, savory au jus is the star, so you don’t need overly complicated sides.
