French Dip Squares are a tasty twist on the classic sandwich you know and love. These little bites pack tender roast beef, melty cheese, and a hint of onion all pressed together in a soft, buttery dough. They’re perfect for sharing or enjoying as a fun snack with a side of rich, savory dipping sauce.
I love making these because they’re so easy to grab and share at parties or family gatherings. Plus, they come together quickly, which is a big win for busy days. I usually serve them warm right out of the oven when the cheese is gooey and the crust is golden—it’s just the kind of comforting bite that makes everyone smile.
One thing I like to do is prepare a simple au jus or beef broth on the side for dipping. It brings that classic French dip flavor and keeps the squares nice and juicy. Whether you’re feeding a crowd or just want a cozy snack, these squares are always a hit at my house!

Key Ingredients & Substitutions
Crescent Roll Dough: This is your base crust for the squares. It’s soft and buttery, but you can swap it for biscuit dough or even puff pastry for a flakier texture. Just press it evenly to avoid uneven baking.
Roast Beef: Thinly sliced roast beef works best here. Deli-style beef or leftover roast are both great options. If you want to skip beef, thin slices of turkey or chicken can work, but the flavor won’t be quite the same.
Onions: Caramelized onions add sweetness and depth. Using yellow or sweet onions gives the best flavor. You can add a touch of balsamic vinegar while cooking the onions for a little zing.
Swiss or Provolone Cheese: These melt beautifully with a mild flavor that complements the beef. If you prefer, mozzarella or Monterey Jack are good melty alternatives.
Beef Broth (Au Jus): This is key for dipping. Use low-sodium beef broth to control saltiness or make a quick au jus with beef drippings, broth, and a splash of Worcestershire sauce for richer flavor.
How Do You Get Perfectly Caramelized Onions for Sweet, Flavorful Layers?
Caramelizing onions is all about low and slow cooking to bring out their natural sweetness and soft texture. Quick cooking makes them harsh, so patience is key.
- Heat olive oil or butter over medium-low heat before adding onions.
- Cook slowly, stirring every few minutes to avoid burning. This takes 10-15 minutes.
- Add salt to help release moisture and enhance sweetness.
- If onions start to stick, add a splash of water to deglaze the pan.
- Cook until onions turn a deep golden brown but are not burned.
I like to caramelize just enough for color and sweetness. This step adds a rich, mellow base to the squares and elevates the whole dish.
Equipment You’ll Need
- 9×13 inch baking dish – perfect size to press the dough evenly and bake the squares all at once.
- Skillet or frying pan – you’ll use it to caramelize the onions nicely without burning.
- Mixing bowl – handy for mixing your seasoning before sprinkling on top.
- Sharp knife or pizza cutter – makes cutting the squares clean and easy.
- Basting brush (optional) – great if you want to brush melted butter over the crust for extra golden color.
Flavor Variations & Add-Ins
- Swap roast beef for shredded rotisserie chicken for a lighter, milder version that’s still juicy.
- Add sautéed mushrooms with the onions to bring an earthy flavor that pairs well with beef.
- Try pepper jack cheese instead of Swiss for a bit of creamy spice and extra meltiness.
- Mix fresh thyme or rosemary into the seasoning for a fragrant herbal kick, especially if you love aromatic baked dishes.
Delicious French Dip Squares Recipe
Ingredients You’ll Need:
For the Squares:
- 1 package refrigerated crescent roll dough (or biscuit dough)
- 1 ½ pounds thinly sliced roast beef (deli-style or leftover roast)
- 2 cups sliced onions
- 1 tbsp olive oil or butter
- 2 cups shredded Swiss cheese or provolone cheese
- 1 tsp garlic powder
- 1 tbsp dried parsley (plus extra for garnish)
- 1 tsp onion powder
- Salt and pepper, to taste
For the Dipping Sauce:
- 2 cups beef broth (for dipping sauce)
How Much Time Will You Need?
This recipe takes about 15 minutes to prep, 10-15 minutes to caramelize onions, and 20-25 minutes to bake. All in all, expect around 45 minutes from start to finish, including a short cooling time before slicing.
Step-by-Step Instructions:
1. Prepare the Oven and Onions:
Preheat your oven to 375°F (190°C). Lightly grease a 9×13 inch baking dish. In a skillet, heat the olive oil or butter over medium heat. Add the sliced onions and cook gently, stirring now and then, until they turn golden brown and caramelized—this should take about 10 to 15 minutes. Season the onions with a pinch of salt and pepper, then remove the pan from heat.
2. Assemble the Squares:
Unroll the crescent roll dough and press it evenly into the bottom of the prepared baking dish to form a base crust. Spread the caramelized onions evenly over the dough. Then, layer the thinly sliced roast beef on top of the onions. Sprinkle the shredded Swiss or provolone cheese evenly over the beef layer.
3. Add Seasoning and Bake:
In a small bowl, mix together the garlic powder, onion powder, and dried parsley. Sprinkle this seasoning mix evenly over the cheese. Place the baking dish in the oven and bake uncovered for about 20-25 minutes, or until the cheese has melted, is bubbly, and the top turns a delicious golden brown color.
4. Cool, Slice, and Serve:
Remove the dish from the oven and let it cool for a few minutes so it holds together better. Cut into squares using a sharp knife or pizza cutter. Serve them warm with hot beef broth or au jus on the side for dipping. Garnish with fresh parsley if you like.
There you have it — cheesy, beefy, delicious French Dip Squares that are perfect for dipping, sharing, and enjoying any time!
Can I Use Frozen Crescent Roll Dough for This Recipe?
Yes, you can! Just be sure to thaw the dough completely in the refrigerator overnight before using. This helps it roll out smoothly and bake evenly.
Can I Make These French Dip Squares Ahead of Time?
Absolutely! Assemble the squares and store them covered in the fridge for up to 24 hours before baking. When ready, pop them in the oven and bake as directed—just add a few extra minutes if baking from cold.
How Should I Store Leftover French Dip Squares?
Store leftovers in an airtight container in the fridge for up to 3 days. To reheat, warm them in the oven at 350°F (175°C) for 10-15 minutes or until heated through for the best texture.
What’s the Best Substitute for Beef Broth in the Dipping Sauce?
If you don’t have beef broth, you can use vegetable broth or chicken broth instead. For richer flavor, add a splash of Worcestershire sauce or soy sauce to the broth before serving.
