The Origins of the French Dip Sandwich

Despite its name, the French Dip sandwich is an American invention. Two Los Angeles restaurants—Philippe the Original and Cole’s Pacific Electric Buffet—both claim to have created it in the early 1900s. While the true origin remains debated, one thing is certain: the combination of thinly sliced roast beef on a crusty roll with a side of rich, beefy jus has stood the test of time.

The idea behind dipping the sandwich in au jus (meaning “with juice” in French) is to add moisture and depth of flavor. Traditionally served on a French baguette, the sandwich has evolved into many variations—including these irresistible sliders that pack all the bold flavors into a smaller, easier-to-eat package.

Why You’ll Love These French Dip Sliders

From spicy horseradish mayo to extra cheese or different meats, these sliders can be tweaked to match your preferences.

5. A Dipping Experience Like No Other

The savory, aromatic au jus adds an extra layer of indulgence, soaking into the sliders just enough to enhance the flavor without making them soggy.

Expert Tips for the Best French Dip Sliders

1. Choose the Right Bread for the Best Texture

Soft, slightly sweet slider rolls (like King’s Hawaiian Butter Rolls) work best because they soak up flavor without falling apart. If you prefer a less sweet option, go for brioche or dinner rolls.

2. Toast the Rolls for a Crispier Bite

Lightly toasting the buns before assembling helps prevent sogginess and adds a pleasant crunch to each bite.

3. Use High-Quality Roast Beef

Deli-sliced roast beef is a great shortcut, but choosing a high-quality cut makes a huge difference. Ask for it thinly sliced but not paper-thin to maintain texture and juiciness.

4. Caramelized Onions Add Depth of Flavor

Caramelizing onions low and slow brings out their natural sweetness, which pairs perfectly with the savory beef and melty cheese. If short on time, sauté them over medium heat with a pinch of sugar to speed up the process.

5. Use a Two-Step Baking Method for the Perfect Finish

• Step 1: Cover the sliders with foil and bake to melt the cheese and warm the beef.
• Step 2: Uncover and bake until the tops are golden brown and slightly crisp.

6. Don’t Skip the Buttery Glaze

Brushing a savory butter mixture over the sliders before baking ensures flavor in every bite. The combination of garlic, Worcestershire sauce, and fresh parsley enhances the richness of the dish.

7. Simmer the Au Jus for the Best Flavor

A simple au jus made with beef broth, Worcestershire sauce, butter, and herbs enhances the overall experience. Simmering for 10 minutes deepens the flavors—strain it for a smooth, restaurant-quality dipping sauce.

Creative Variations to Try

1. Spicy French Dip Sliders

• Add sliced jalapeños between the layers.
• Use pepper jack cheese instead of Swiss or provolone.
• Mix hot sauce or extra horseradish into the mayo.

2. Garlic Butter French Dip Sliders

• Add minced garlic to the butter topping.
• Brush extra garlic butter inside the buns before assembling.

3. Philly Cheesesteak-Inspired Sliders

• Swap roast beef for thinly sliced ribeye.
• Add sautéed bell peppers and mushrooms.
• Use white American or provolone cheese.

4. Turkey French Dip Sliders

• Replace roast beef with sliced turkey for a lighter option.
• Pair with mild cheese like Havarti or gouda.

5. BBQ French Dip Sliders

• Mix barbecue sauce with the au jus for a smoky twist.
• Add crispy fried onions for extra texture.

Frequently Asked Questions (FAQs)

1. Can I Make These Sliders Ahead of Time?

Yes! Assemble the sliders up to 4 hours in advance, but wait to add the butter topping until just before baking to keep the rolls from getting too soft.

2. Can I Use a Different Type of Cheese?

Absolutely! Swiss and provolone are the most common choices, but you can also use:

• Cheddar for a sharp, bold taste.
• Mozzarella for an extra gooey texture.
• Gruyère for a slightly nutty, elevated flavor.

3. What’s the Best Way to Store and Reheat Leftovers?

• Store: Keep sliders in an airtight container in the fridge for up to 3 days.
• Reheat: Wrap in foil and bake at 350°F (175°C) for 10-15 minutes.
• Re-crisp: Remove the foil and bake uncovered for another 5 minutes.

4. Can I Freeze These Sliders?

Yes! Freeze assembled but unbaked sliders wrapped tightly in plastic wrap and foil. Bake straight from frozen at 325°F for 25-30 minutes, then uncover and bake until golden.

5. Can I Make the Au Jus Without Flour?

Yes! The flour simply thickens the jus slightly. If you prefer a thinner sauce, omit the flour and simmer the broth with butter and Worcestershire sauce.
