The Cooking Process Explained
Making French Dip Squares is delightfully straightforward. You’re essentially layering roast beef and cheese onto puff pastry or crescent roll dough, sealing it up, and baking until golden. The real magic happens when you pair them with a warm, savory au jus for dipping – that’s where the “French Dip” truly comes alive. We’ll then explore how this basic concept can be twisted into seven different, equally delicious lunch ideas.
What You’ll Need
Gather these items for your basic French Dip Squares, and then we’ll dive into variations!
- 1 can (8 oz) refrigerated crescent rolls or 1 sheet frozen puff pastry, thawed
- 1 lb thinly sliced deli roast beef
- 6 slices provolone cheese (or Swiss cheese)
- 2 tbsp melted butter
- 1/2 tsp garlic powder
- 1/4 tsp onion powder
- For dipping: 1 packet (0.6 oz) au jus mix OR 1.5 cups beef broth + 1 tsp Worcestershire sauce.
Directions to Follow
Let’s get these delicious squares baking!
- Prep Your Oven & Dough: Preheat your oven to 375°F (190°C). If using crescent rolls, unroll the dough but don’t separate the triangles. Press the seams together to form a single rectangle. If using puff pastry, unfold it onto a lightly floured surface.
- Layer the Goodness: Lay the provolone slices evenly over the dough. Top with the thinly sliced roast beef, spreading it out to cover the cheese.
- Roll or Fold: Carefully roll the dough from one long side to the other, creating a log. If using puff pastry, you might prefer to fold one side over the filling to meet the other side, then press the edges to seal.
- Slice & Arrange: Using a sharp knife, cut the log or folded pastry into 1-inch thick squares. Arrange the squares, slightly spaced apart, on a baking sheet lined with parchment paper.
- Flavor Boost: In a small bowl, mix the melted butter with garlic powder and onion powder. Brush this mixture generously over the tops of each square.
- Bake: Bake for 15-20 minutes, or until the pastry is golden brown and puffed, and the cheese is melted and bubbly.
- Au Jus Prep: While the squares are baking, prepare your au jus. If using a packet, follow package directions. If making from scratch, combine beef broth and Worcestershire sauce in a small saucepan and bring to a simmer over medium heat. Keep warm.
- Serve Hot! Serve the French Dip Squares immediately with the warm au jus for dipping.
How to Serve Your French Dip Squares
The beauty of French Dip Squares is their versatility, especially for lunch. Here are some creative ideas beyond just serving them with au jus:
- Classic Dip: Of course, a warm, savory au jus is non-negotiable. It’s what makes them “French Dip”!
- Simple Side Salad: A light green salad with a tangy vinaigrette cuts through the richness of the beef and cheese beautifully.
- Crisp Veggies: Carrot sticks, celery, or bell pepper strips offer a refreshing crunch and color.
- Pickle Power: Dill pickles or cornichons provide a delightful acidic counterpoint.
- Soup & Square Combo: Pair with a simple tomato soup or a creamy mushroom soup for a heartier meal.
- Gourmet Garnish: A sprinkle of fresh chives or parsley adds a touch of elegance.
Keeping Leftovers Fresh
French Dip Squares are best enjoyed fresh out of the oven, but leftovers can be managed.
- Storage: Store any leftover squares in an airtight container in the refrigerator for up to 2-3 days. Keep the au jus separate.
- Reheating: Reheat in a preheated oven or toaster oven at 350°F (175°C) for about 5-10 minutes, or until warmed through and the pastry is crisp again. Avoid the microwave if possible, as it can make the pastry soggy. Reheat the au jus gently on the stovetop or in the microwave.
- Freezing: While theoretically possible, freezing is not recommended as the pastry can become quite soft and less appealing after thawing and reheating.
Pro Chef Tips
A few small adjustments can elevate your French Dip Squares from good to absolutely amazing:
- Quality Roast Beef: Since roast beef is a star ingredient, opt for a good quality, thinly sliced deli roast beef. Ask for it sliced “shaved” or “extra thin” for the best texture.
- Puff Pastry vs. Crescent Rolls: Puff pastry will give you a flakier, more delicate square, while crescent rolls offer a slightly softer, more bread-like texture. Experiment to see which you prefer!
- Don’t Overstuff: While it’s tempting toPile on the beef and cheese, too much filling can make it hard to roll and can cause the pastry to burst.
- Seal Those Edges: Ensure your seams are well-pressed, especially if using crescent roll dough, to prevent the filling from oozing out.
- Score for Success: If using puff pastry, a few shallow scores on the top before baking can help it puff more evenly.
- Batch Bake Au Jus: For convenience, you can make a larger batch of au jus and freeze portions for future use.
Creative Twists
Here are 7 quick lunch ideas using the French Dip Squares as your delicious starting point:
- The Classic Lunchbox: Pack your baked French Dip Squares with a small container of warm au jus (use a thermos!), a side of baby carrots, and an apple. Simple and satisfying.
- Ranch Dip & Veggies: Instead of au jus, serve the squares with a creamy homemade ranch dip and a medley of fresh bell pepper strips, cucumber, and cherry tomatoes.
- Spicy Horseradish Kick: Mix a dollop of prepared horseradish into your au jus, or serve a small dish of horseradish cream on the side for an extra zing.
- Open-Faced Melts: Don’t roll them! Simply layer roast beef and provolone onto individual squares of crescent dough or puff pastry, bake, and serve open-faced with a sprinkle of fresh parsley.
- “Philly Style” Squares: Before baking, add some thinly sliced sautéed onions and green peppers (cooked until tender) over the roast beef for a nod to a Philly cheesesteak. A drizzle of mild cheese sauce instead of au jus works too!
- Mushroom & Swiss Upgrade: Swap the provolone for Swiss cheese, and add a thin layer of sautéed mushrooms (drained well) over the roast beef before rolling.
- Breakfast for Lunch: Serve the squares with a side of scrambled eggs and a small fruit salad for a unique and hearty brunch-style lunch.
Common Questions
How can I make these ahead of time?
You can assemble the squares (up to step 4, before baking) and store them covered in the refrigerator for up to 24 hours. Brush with butter mixture and bake just before serving for the best results.
Can I use different types of cheese?
Absolutely! Swiss is a classic choice for French dip, but mozzarella or even a sharp cheddar could work if you prefer. Just ensure it melts well.
Is there a vegetarian alternative?
While the “French Dip” part is usually beef-centric, you could adapt the concept! Try using thinly sliced portobello mushrooms (marinated and roasted) or a plant-based roast substitute, along with a vegetable-based gravy or broth for dipping.
My pastry isn’t very flaky; what did I do wrong?
If using crescent rolls, they are inherently less flaky than puff pastry. If using puff pastry and it’s not flaky, ensure it was properly thawed but still cold when working with it. Also, avoid overworking the dough, which can toughen it.

Method
- Preheat oven to 400°F (200°C) and line a baking sheet with parchment paper.
- On a lightly floured surface, unroll and gently roll out the thawed puff pastry to about a 10×12-inch rectangle.
- In a small bowl, combine mayonnaise, Dijon mustard, Worcestershire sauce, and garlic powder, mixing until smooth.
- Spread the mayo mixture evenly over the puff pastry, leaving a ½-inch border on one long edge.
- Arrange the roast beef over the mayo mixture, then top with provolone cheese slices.
- Starting from the long edge opposite the border, tightly roll the pastry into a log and pinch the seam to seal.
- Cut the log into 1-inch thick slices, yielding 10-12 squares, and place them cut-side up on the prepared baking sheet.
- Bake for 15-18 minutes, or until the pastry is puffed and golden brown and the cheese is melted and bubbly.
- While baking, warm the beef broth or au jus in a small saucepan over medium-low heat.
- Let the squares cool, then serve warm with the hot au jus for dipping.
