The beef dip sandwich, often referred to as the French Dip, is a cornerstone of American deli culture. It is a deceptively simple masterpiece consisting of thinly sliced roast beef tucked into a crusty baguette and served with a side of savory, salty au jus for dipping. Whether you are looking for a comforting weeknight dinner or a crowd-pleasing meal for a weekend gathering, mastering the art of the beef dip is a skill every home cook should possess.
While the origins of the sandwich are debated between two legendary Los Angeles eateries, the consensus on what makes a great one is clear: tender meat, high-quality bread, and a dipping sauce that packs a punch of umami flavor. In this guide, we will walk through every step of the process, from selecting the right cut of meat to the secret ingredients that make an unforgettable au jus.
Selecting the Best Beef for Your Sandwich
The foundation of any great beef dip is, unsurprisingly, the beef. Because the meat is sliced thin and submerged in liquid, you want a cut that is flavorful and can stand up to the roasting or slow-cooking process without becoming tough or stringy.
Top Round or Bottom Round
These are the most traditional choices for a deli-style sandwich. They are lean, affordable, and easy to slice thinly once cooked. When roasted to a perfect medium-rare, these cuts provide a clean beefy flavor that allows the au jus to shine.
Chuck Roast
If you prefer a sandwich that is more “shredded” or fall-apart tender, a chuck roast is your best friend. This cut has more fat and connective tissue, which breaks down during a slow-cook process (like in a crockpot or Dutch oven). This results in a rich, juicy texture that is incredibly satisfying.
Ribeye or Prime Rib
For a truly decadent, “splurge” version of the beef dip, leftover prime rib is the gold standard. The marbling in a ribeye roast provides a buttery mouthfeel that no other cut can match. If you are making this from scratch specifically for sandwiches, it is a more expensive route, but the results are undeniably gourmet.
The Secret to the Perfect Au Jus
The term “au jus” literally translates from French to “with juice.” In the world of sandwiches, it refers to the light gravy or dipping broth served alongside. A common mistake is using a thin, salty bouillon; a truly great au jus has depth, acidity, and a hint of herbal notes.
To build a professional-grade dipping sauce, start with a base of high-quality beef stock. Enhance this base by sautéing aromatics like onions, garlic, and even a little bit of celery. A splash of Worcestershire sauce and a tablespoon of soy sauce can provide that deep, dark color and savory “fifth taste” known as umami. For acidity, a small amount of red wine or a teaspoon of balsamic vinegar helps cut through the richness of the beef fat.
Step-by-Step Instructions for the Classic Oven Method
This method is ideal if you want those beautiful, uniform slices of beef often found in high-end sandwich shops.
-
Preparing the Roast
Begin by seasoning your beef generously. A simple rub of kosher salt, cracked black pepper, garlic powder, and dried thyme is classic. Preheat your oven to 450 degrees Fahrenheit to start.
Place the roast on a rack in a roasting pan. Sear it at this high temperature for about 15 minutes to develop a brown crust. Then, lower the oven temperature to 325 degrees Fahrenheit and continue cooking until the internal temperature reaches 130 degrees Fahrenheit for medium-rare.
-
The Importance of Resting
Once the beef comes out of the oven, resist the urge to slice it immediately. Let it rest on a cutting board for at least 20 to 30 minutes. This allows the juices to redistribute throughout the meat. If you slice it too soon, all that flavor will spill out onto the board, leaving you with dry meat.
-
Crafting the Sauce
While the meat rests, use the drippings left in the roasting pan. Place the pan over a stovetop burner, add a splash of beef broth to deglaze the fond (the brown bits stuck to the bottom), and then whisk in your remaining broth and seasonings. Simmer until it reduces slightly and the flavors are concentrated.
The Slow Cooker Method for Busy Weekdays
If you want to come home to the smell of a ready-to-eat meal, the slow cooker is the way to go. This method works best with a chuck roast.
Place your roast in the slow cooker with a cup of beef broth, a sliced onion, several cloves of smashed garlic, and a bay leaf. Set the cooker to low and let it glide for 8 to 10 hours. By the time you are ready for dinner, the meat will be tender enough to shred with two forks. The liquid remaining in the pot becomes your au jus—just strain it through a fine-mesh sieve to remove the solids before serving.
Choosing and Preparing the Bread
The bread is the unsung hero of the beef dip sandwich. It needs to be sturdy enough to be dunked into liquid without disintegrating, yet soft enough to bite through easily.
The French Baguette
A traditional French baguette is the most popular choice. Its crusty exterior provides a necessary structural integrity. For the best experience, slice the baguette into sandwich-sized portions, split them lengthwise, and lightly toast them under a broiler with a swipe of butter and perhaps a hint of garlic salt.
Hoagie Rolls or Bolillo Rolls
If you prefer a softer bite, a high-quality hoagie roll or a Mexican bolillo roll works beautifully. These rolls have a tighter crumb and can absorb a significant amount of jus without falling apart instantly.
Toppings and Variations
While a “pure” beef dip only consists of meat, bread, and juice, many people enjoy adding layers of flavor.
Cheese Options
Provolone is the standard choice because it melts beautifully and has a mild, creamy flavor that doesn’t overpower the beef. Swiss cheese or a sharp white cheddar are also excellent alternatives. Place the cheese on the bread and melt it under the broiler before adding the meat.
Horseradish and Onions
For a bit of “kick,” spread a thin layer of horseradish cream on the top half of your roll. Caramelized onions are another fantastic addition, adding a touch of sweetness that balances the salty au jus.
Assembly and Serving
To assemble the perfect sandwich, dip your sliced or shredded beef directly into the hot au jus for a few seconds before piling it onto the toasted roll. This ensures the meat is moist and seasoned throughout.
Serve the sandwich on a plate with a small individual ramekin or bowl of the hot dipping sauce on the side. Traditionally, this meal goes well with a side of potato chips, a crisp dill pickle, or a simple green salad to provide a fresh contrast to the heavy, savory flavors of the beef.
Common Mistakes to Avoid
One of the biggest pitfalls is overcooking the beef. If using the roasting method, use a meat thermometer. Even a few degrees can be the difference between a succulent sandwich and a tough one.
Another mistake is neglecting the au jus seasoning. Always taste your sauce before serving. If it tastes flat, it likely needs a pinch more salt or a tiny splash of acid (like lemon juice or vinegar) to wake it up.
Lastly, don’t skip toasting the bread. The toasted surface creates a barrier that prevents the bread from turning into mush the moment it touches the sauce.
Frequently Asked Questions
-
What is the difference between a French Dip and an Italian Beef sandwich?
While both involve beef and bread, the Italian Beef sandwich originates from Chicago and features beef simmered with Italian herbs and spicy pickled vegetables known as giardiniera. The French Dip is generally simpler, focusing on the natural flavor of the beef and a savory au jus, usually without the spicy vegetable topping.
-
Can I make beef dip sandwiches with deli roast beef?
Yes, you can! If you are short on time, buy high-quality, rare roast beef from the deli counter. Ask them to slice it as thin as possible. You can then make a quick au jus on the stove using beef base, Worcestershire sauce, and seasonings, and briefly warm the deli meat in the simmering sauce before assembly.
-
How do I store and reheat leftovers?
Store the beef and the au jus in separate airtight containers in the refrigerator for up to three days. To reheat, warm the au jus in a small saucepan and then add the meat to the hot liquid just until it is warmed through. Avoid microwaving the meat on high power, as this can make it rubbery.
-
What can I use if I don’t have beef broth for the au jus?
If you are out of beef broth, you can use beef bouillon cubes or paste mixed with water. In a pinch, a combination of vegetable broth and a bit of extra soy sauce or Worcestershire sauce can mimic the savory depth of beef broth, though the flavor will be slightly different.
-
Should I dip the whole sandwich or just the end?
This is a matter of personal preference! Some people like to “double dip,” submerging the entire sandwich briefly before each bite, while others prefer to just dip the corner of the sandwich to keep the bread crispier. There is no wrong way to enjoy a beef dip.
