Foil Pack French Dip Sandwiches made easy in a foil pack. Perfect for grilling, taking camping, or even cooking in your oven! (Great make ahead option)
Foil Pack French Dip Sandwiches
These french dip sandwiches make such a fun dinner! They’re SO simple and everyone will love getting their own packet of “miniature” sandwiches! Not to mention, who doesn’t love having a dip on the side?!
Not only do they make a great weeknight dinner (fast + easy), they are also the perfect thing to bring camping or to enjoy over a camp-out. You can make the sandwiches beforehand — just pack the foil-wrapped sandwiches in a big ziplock bag (and if you want the dip: the remaining au jus, a campfire pot, whisk, and some water) and throw it all in a cooler. Come dinner time, you can throw the sandwiches over the grill and prepare the au jus sauce. (Or prepare it beforehand and just warm it up over the fire).
These foil pack french dip sandwiches are also perfect for over the grill (this is our favorite way to enjoy them!) and if your grill has a side burner, you can make the au jus while they’re cooking.
However you make these I’m sure you’ll love them!

Foil Pack French Dip Sandwiches
Ingredients
- 1/2 cup (8 tablespoons) unsalted butter softened to room temperature
- 1 package au jus gravy mix divided
- 1 teaspoon Worcestershire sauce
- 3/4 teaspoon dried minced garlic
- 1/2 teaspoon onion powder
- Heavy Duty Foil
- 1 long/large (or 2 smaller) baguettes
- 1 pound deli roast beef (ask for rare, since it's getting cooked)
- 1 package pre-sliced (12 slices total) provolone cheese
Instructions
- Preheat a grill to medium-high heat (400 degrees) or the oven to 400 degrees F.
- Start by making the butter mixture. Combine the softened (not melted) butter, 1 tablespoon of the au jus gravy mix, Worcestershire sauce, dried minced garlic, and onion powder in a bowl. Stir until ingredients are completely combined and set aside.
- Cut the baguette into equal parts of about 6-10 inches in length. Next, make an ODD number of thin slices (approx. 1/2 inch wide) into each piece of the baguette, cutting only about 3/4 the way through. It's important there are an ODD number of slices so that each sandwich has 2 pieces of bread.
- Separate the butter mixture created in step 2 into 2 equal parts. Using a butter knife, spread a small amount of the mixture inside each slice of bread. Save half of the mixture for later.
- Slice the individual pieces of cheese in half and place 1 piece, along with 1 piece of roast beef, in-between every two "slices" of bread. (Again, these will be individual pull-apart sandwiches, so you don't want cheese and meat in-between each slice).
- Take the other half of the butter mixture and brush it along the tops and sides of each of the sandwiches with a pastry brush.
- Wrap each baguette section completely in foil. Make sure none of the bread is exposed.
- Place in the preheated oven for 10 minutes or the preheated grill for 6-9 minutes (turning frequently) or until bread is toasty and cheese is melted. If you have a thicker baguette it will take longer.
- While the sandwiches are cooking, prepare the au jus. Take the remaining au jus mixture and place in a small saucepan over medium heat. Add 2 cups cold water and whisk. Bring to a boil and then reduce the heat to a simmer to allow it to slightly thicken. (You can do this on the side burner of a grill or even over a campfire OR make ahead of you bring these sandwiches camping)
- Remove foil packs and open carefully to let the steam escape. Pull apart the sandwiches and enjoy with the au jus sauce.

Wow – this is amazing!! I made this in the oven and it was perfect! Will be making this again! I made no changes to the recipe and loved it!!
So happy to hear that! 🙂
Aloha! What brand au jus do you use?
I’ve made this 3 times and it’s great. I make a few changes.
1 I double the butter
2 I use 1 Lipton onion soup mix in place of the au jus. That way I can make it on the campus g trip and don’t have to bring extra ingredients.
3 I think you could do 3/4 lb roast beef. I can’t get much inside the little sandwiches.
Thank you for great recipe!
I love a good French dip !! These hit it out of the park …. amazing thanks so much for sharing your recipe ????
I am so happy to hear this Jasmine! Thanks so much for your comment! 🙂
I made this tonight over the campfire. Oh my they are so good! Great recipe!
I’m so glad you enjoyed this! Thanks for your comment Samantha! 🙂
I made this over the fire tonight. Oh my they are delicious!! So good. Great recipe!
I’m so happy you enjoyed this recipe! Thanks so much for your comment! 🙂
Did you use a grate or just put them on the coals?
I used a grate
I’d like to pre-make these to take on a camping trip. How many days do you think I could have them packed in a cooler before cooking over the fire and serving? One day? Two days?
Honestly I’m worried even a day in advance they’d be a bit soggy :/ If you do make them in advance, I wouldn’t do it more than a day ahead
Could you make the step 2 part of recipe beforehand when camping?
Yes, just keep it in an air tight container and let sit out a bit before using so the butter will soften again if it has hardened. Hope this helps! Thanks Luke!
My husband had been asking for French dip sandwiches for eons now and since he puts up with all the vegan food I force on him, he deserved something extra yummy! And this knocked it out of the park! He inhaled it so I’m making it again tonight. Thank you!
So happy to hear it! Thanks for the comment Victoria 🙂
My wife and I could not believe how fantastic this turned out , they were absolutely delicious!! If you’re reading this and you’re thinking about trying it, do it !!!!
Yayyy!! I am soo happy to hear this! Thanks so much! 🙂
How would you recommend reheating/heating over the campfire?
This is an outstanding recipe. Also, thank you for adjusting the Au Jus water to be added after using 1tbs for the butter mix. Instead of 3 cups on the package, your recipe reminded me to only use 2. Thanks!
Yay!! I’m so glad you enjoyed it! Thanks! 🙂
How did you make the au Jus sauce.
I saw someone said cutting back on water. Need to know how much did a scout group of 25.
