French Dip Squares

French Dips with a twist!

On the surface, French dip sandwiches aren’t too different than regular roast beef sandwiches. You’ve got meat, cheese, veggies, and mustard. But once you toast this sandwich and dunk it into au jus, I think you’ll agree it’s pure magic.

There are very few sandwiches I’d consider filling enough to make for dinner, but French dips are one of them, and even more so with these French Dip Squares! Serve these bad boys up with a side of veggies or fries, and you’ll have a delicious dinner the whole family will love.

This recipe has everything you know and love about French dips all wrapped up in different package. In fact, I might like these squares better than the original! Plus, nothing beats homemade au jus. If you think you’re in over your head with this recipe, think again!

These French Dip Squares are made easy by using refrigerated biscuit dough. Start by rolling out one of the cans of dough on a flat surface and pinching the seams together. Bake the dough for about 12 minutes, or until the edges are golden brown. While the crust is baking, go ahead and sauté the onions, thyme, salt, and pepper together until tender.

Next, it’s time to assemble the squares. Spread a layer of whole-grain mustard on the baked crust, followed by sliced roast beef, provolone, and caramelized onions. Roll out the remaining can of dough and lay it on top, pinching the edges to seal the edges.

Pop the pan back into the oven for another 35 minutes and get to work on the sauce. beef stock, Worcestershire sauce, and thyme make up this homemade au jus. Once the squares are fully cooked, slice them up and dip away!
