These 15-Minute Roast Beef Dip Sandwiches Are A Super Easy Family Dinner
This is the mom-on-the-go version of the classic French dip sandwiches. Although I do love a good slow cooker roast beef dip sandwich, I default to this meal about every other week. It upgrades a regular deli sandwich, and since it is warm, it’s perfect for a days where you want quick comfort food.
How to Make Purple Sweet Potato Fries
Now let’s talk about these PURPLE sweet potato fries. My heart rate elevated with excitement when I saw the bags piled at the entrance of Trader Joe’s. It’s not everyday you get your hands on purple sweet potatoes. Without a special trip to the farmer’s market, anyway.
I immediately grabbed a bag and tossed it in my cart, knowing they would make the coolest french fries. I told my boys they are Ninja Turtle french fries, specifically what Donatello eats to stay strong. And purple. It worked like magic.
The best way to cut these is in with a mandolin. I use my spiralizer because it has a julienne cut, French fry style attachment. Or you can do them by hand, if you’re a whiz with your knife skills. Either way, they make stupidly delicious purple sweet potato fries!
This is a healthy alternative to fries and hot sandwiches, because the fries are roasted and the meat and veggies are light and fresh. It doesn’t have to be excessively heavy to be a cozy meal. But it’s still packed with flavor. And quick! Two of my favorite things. (Cue Julie Andrews.)

15-Minute Roast Beef Dip Sandwiches with Purple Sweet Potato Fries
Roast Beef Sandwiches:
- 4 hoagie rolls
- 1 tablespoon olive oil
- 1 green pepper sliced
- 1/2 red onion sliced
- 1/2 pound sliced deli roast beef
- 4 slices provolone cheese
- Salt and pepper to taste
Au Jus Dip:
- 2 cups beef broth
- 1 tablespoon soy sauce
- 1/2 teaspoon salt
- 1/4 teaspoon garlic powder
- 1/4 teaspoon pepper
Roasted Purple Sweet Potato Fries:
- 2-3 large purple sweet potatoes julienned
- 2 tablespoons olive oil
- Salt and pepper
- Preheat oven to 450°F.
- Place the hoagie rolls face down on a parchment lined baking sheet. Spread out julienned purple sweet potatoes (cut to 1/4 inch thickness) on another parchment lined baking sheet, and drizzle with olive oil, salt, and pepper. Toast the rolls for 5 minutes, and roast the sweet potato fries for 25 minutes. (Note that the thinner fries are cut, the crispier they will turn out.)
- In a skillet, grill the peppers and onions in olive oil on medium high heat, about 5 minutes. When slightly charred and tender, remove and set aside.
- Flip the hoagie rolls and layer meat and one slice of provolone on each sandwich. Bake for another 5-7 minutes until cheese is melted and bubbling, and the bun is toasted.
- While sandwiches and fries are baking, prepare the au jus dip. In a small saucepan, whisk together beef broth, soy sauce, salt, garlic powder, and pepper. Heat over medium high heat, about 5 minutes, until warm.
- Top the baked sandwiches with grilled peppers and onion. Serve with 1/2 cup au jus dip and a side of fries. Enjoy!
