Mastering the Art of Foil Pack Cooking

Foil pack cooking isn’t just a trend; it’s a smart way to prepare meals. It locks in moisture and flavor, allows for easy customization of individual portions, and significantly reduces cleanup. When making these French Dip sandwiches, remember these tips for foil pack perfection:

Heavy-Duty Foil is Key: Invest in good quality, heavy-duty aluminum foil to prevent tears and leaks, especially when grilling or cooking over a campfire.
Seal Tightly: Ensure each packet is sealed tightly to trap all the delicious flavors and moisture, creating a steamy environment that melts the cheese and warms the beef beautifully.
Double Layer for Durability: For extra protection, especially when using standard foil or cooking directly over coals, consider using a double layer of foil for each sandwich pack.
Even Heat Distribution: Whether in the oven or on the grill, try to arrange the packets in a single layer to ensure they cook evenly.
Careful Opening: Always open foil packs carefully away from your face to avoid steam burns.

Essential Ingredients for the Perfect French Dip

The magic of these sandwiches lies in their simple yet high-quality ingredients. Here’s a closer look at what makes them so special:

Baguette: A fresh, crusty baguette is crucial. It holds up well to the rich fillings and the au jus. Cut it into individual portions but don’t slice all the way through, creating a “pull-apart” style sandwich.
Deli Roast Beef: Opt for thinly sliced deli roast beef. Asking for it rare is a great tip, as it will continue to cook and heat through within the foil pack without becoming tough.
Provolone Cheese: This cheese melts beautifully and adds a wonderfully mild, tangy creaminess that pairs perfectly with the beef. You can also experiment with Swiss or Monterey Jack for a slight variation.
Savory Butter Mixture: This is the secret weapon! A blend of softened unsalted butter, au jus gravy mix, Worcestershire sauce, dried minced garlic, and onion powder is slathered both inside and outside the bread. It infuses the baguette with incredible flavor and helps create a lovely toasted exterior.
Au Jus Gravy Mix: The heart and soul of any French Dip! A good quality au jus mix, prepared simply with water, creates the savory dipping sauce that elevates these sandwiches from good to unforgettable.

Tips for a Flawless French Dip Experience

To ensure your foil pack French dip sandwiches are nothing short of spectacular, consider these additional tips:

Pre-slice the Baguette: Make sure to cut the baguette almost all the way through, creating individual sections that are easy to pull apart after cooking. An odd number of slices per baguette section ensures each “mini-sandwich” has two bread pieces.
Butter Application: Don’t skimp on the butter mixture! Spreading it generously inside the slices and over the top and sides of the baguette will create a deliciously golden, flavorful crust.
Don’t Overstuff: While it’s tempting to load up on meat and cheese, ensure there’s enough room for the cheese to melt and the flavors to meld without bursting the foil pack.
Monitor Cooking Times: Grills and ovens can vary. Keep an eye on your sandwiches – you’re looking for toasted bread and perfectly melted cheese. Thicker baguettes may require a few extra minutes.
Au Jus Consistency: Adjust the au jus consistency to your liking. If you prefer it thinner, add a touch more water; for a thicker dip, let it simmer a little longer.

Equipment

Heavy-duty aluminum foil
Small saucepan

Ingredients

8 tablespoons unsalted butter (1/2 cup, 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
1 long/large baguette (or 2 smaller ones)
1 pound deli roast beef (ask for rare, as it will cook further)
12 slices provolone cheese (1 pre-sliced package)

Instructions

Preheat a grill to medium-high heat (400°F) or the oven to 400°F.
Start by making the savory butter mixture. In a bowl, combine the softened (not melted) butter, 1 tablespoon of the au jus gravy mix, Worcestershire sauce, dried minced garlic, and onion powder. Stir until all ingredients are completely combined and set aside.
Prepare the baguette: Cut the baguette into equal sections, approximately 6–10 inches in length. Next, make an odd number of thin slices (about 1/2 inch wide) into each baguette piece, cutting only about 3/4 of the way through. This ensures each individual pull-apart sandwich will have two pieces of bread.
Divide the butter mixture: Separate the butter mixture created in step 2 into two equal parts. Using a butter knife, spread a small amount of the mixture inside each slice of bread. Reserve the remaining half of the mixture for later.
Assemble the sandwiches: Slice the individual pieces of provolone cheese in half. Place one piece of cheese, along with one piece of roast beef, between every two “slices” of bread. (Remember, these are individual pull-apart sandwiches, so you want cheese and meat forming distinct fillings, not between every single bread slice).
Apply remaining butter: Take the other half of the butter mixture and brush it generously along the tops and sides of each assembled baguette section with a pastry brush.
Wrap in foil: Wrap each baguette section completely and tightly in heavy-duty aluminum foil. Ensure no bread is exposed to prevent drying out and to steam the sandwich effectively.
Cook the sandwiches: Place the foil-wrapped sandwiches in the preheated oven for 10 minutes, or on the preheated grill for 6–9 minutes (turning frequently). Cook until the bread is toasty and the cheese is thoroughly melted. Thicker baguettes may require a slightly longer cooking time.
Prepare the au jus: While the sandwiches are cooking, prepare the dipping sauce. Place the remaining au jus gravy mix in a small saucepan over medium heat. Add 2 cups of cold water and whisk continuously until combined. Bring the mixture to a boil, then reduce the heat to a simmer, allowing it to slightly thicken to your desired consistency. (This can be done on a grill’s side burner, over a campfire, or prepared in advance if you’re taking these sandwiches camping).
Serve and enjoy: Carefully remove the foil packs from the heat and open them to allow steam to escape. Pull apart the individual sandwiches and serve immediately with the warm, savory au jus sauce for dipping.

Recipe Notes

Storage: Store leftover sandwiches by wrapping them tightly in foil and refrigerating for up to 3 days. Reheat in the oven at 350°F until warmed through and cheese is re-melted. Store any remaining au jus separately in an airtight container in the fridge and reheat on the stovetop or in the microwave.
