How to Make French Dip Squares
Step 1: Preheat the Oven
Preheat your oven to 350°F. Spray a 9×13-inch baking dish with nonstick cooking spray and set aside.
Step 2: Prepare the Onions
In a large skillet over medium heat:
1. Melt 4 tablespoons salted butter.
2. Add in the 3 cups small-diced onion, 2 teaspoons granulated sugar, and ½ teaspoon black pepper.
3. Stir to combine and cook frequently until the onions turn golden brown.
4. Remove from heat and transfer onto a separate plate until ready to assemble.
Step 3: Assemble the Dough Layers
- Unroll one tube of crescent dough sheets into the prepared baking dish, pressing it up the sides about an inch.
- Lay half of the sliced provolone cheese over the dough.
- Add all of the deli-sliced roast beef on top of the cheese layer.
- Spread out your cooked onions evenly over the roast beef.
- Place remaining provolone cheese on top before covering with the second crescent dough sheet.

- Brush this mixture generously all over the top of your assembled squares.

How to Perfect French Dip Squares
To ensure your French Dip Squares turn out amazing every time, follow these helpful tips.
- Use Fresh Ingredients: Fresh onions and high-quality roast beef will enhance the flavor profile significantly.
- Avoid Overcooking Onions: Cook onions until golden brown but avoid burning them; this will keep their sweetness intact.
- Seal the Dough Well: Pinch seams tightly to prevent filling from leaking during baking.
- Let Them Cool Slightly: Allowing the squares to cool for 10 minutes makes cutting easier without losing the filling.
- Experiment with Cheese: Try mixing provolone with other cheeses like mozzarella or pepper jack for extra flavor.
- Adjust Seasoning: Taste before baking and feel free to adjust spices according to your preference.
Best Side Dishes for French Dip Squares
Pairing side dishes with French Dip Squares can elevate your meal experience. Here are some great options:
- Garlic Mashed Potatoes: Creamy mashed potatoes infused with garlic make for a comforting addition.
- Coleslaw: A tangy coleslaw adds crunch and balances the richness of the squares.
- Vegetable Soup: A warm bowl of vegetable soup provides warmth and complements the savory flavors of the dish.
- Baked Beans: Sweet and smoky baked beans offer a delightful contrast to the savory dip squares.
- Potato Wedges: Seasoned potato wedges are easy to prepare and provide additional texture alongside your main dish.
- Corn on the Cob: Grilled or boiled corn on the cob is a sweet side that pairs well with savory flavors.
Common Mistakes to Avoid
When making French Dip Squares, it’s easy to overlook some details. Here are common mistakes to avoid for the best results.
- Using too much butter: While butter adds flavor, using excessive amounts can make the dish greasy. Stick to the recipe’s specified amount for perfect results.
- Not cooking onions long enough: Undercooked onions can taste harsh. Ensure you cook them until they are golden brown for better flavor and texture.
- Skipping the egg wash: The egg wash is essential for achieving a beautiful golden crust. Don’t skip this step; it enhances appearance and texture.
- Overfilling with beef: Adding too much roast beef can cause the squares to burst during baking. Follow the recommended amounts for a well-balanced dish.
- Ignoring resting time: Cutting into the squares too soon can lead to a messy serving. Allowing them to cool for 10 minutes helps set the layers.
- Using warm au jus: Serve your au jus warm, not cold, for a more enjoyable dipping experience. Heat it according to package instructions before serving.

Storage & Reheating Instructions
Refrigerator Storage
- Store in an airtight container for up to 3 days.
- Ensure the squares are completely cooled before sealing to prevent moisture buildup.
Freezing French Dip Squares
- Wrap individual squares tightly in plastic wrap, then place in a freezer-safe bag or container.
- They can be frozen for up to 2 months.
Reheating French Dip Squares
- Oven: Preheat to 350°F and bake covered with foil for about 15-20 minutes until heated through.
- Microwave: Heat on medium power in short intervals until warmed, usually 1-2 minutes depending on your microwave’s strength.
