Why you’ll love Steak Frites Sandwich

South Chicago Packing’s beef tallow is the star of today’s recipe! We used it three ways with the spray on the steak, fried the fries in tallow and used warm tallow for the beefonaisse. Making all the classic flavors of steak frites on a sandwich.

I truly do love cooking with their tallow and enjoy the depth of flavor it adds to any dish!

Steak Frites Sandwich Ingredients

You’ll start out with some New York strip steak, seasoning it with kosher salt, black pepper, garlic powder, and South Chicago Packing Beef Tallow Spray. 

Then, you’ll make fries out of russet potatoes, kosher salt, and beef tallow.

Finally, you’ll make your own garlic horseradish beefonnaise out of egg yolks, garlic cloves, South Chicago Packing Beef Tallow, horseradish, white vinegar, dijon mustard, and lemon juice.

Finish off the sandwich with ciabatta bread, sliced cheese, and chimichurri.

How to Make Steak Frites Sandwiches

Fries:

I started this recipe with the fries, so that they could soak in an ice bath for a bit. 

Begin by slicing your potatoes with a mandolin to a thin fry shape. Set the sliced fries into an ice water bath. This helps remove some of the starchy-ness and will result in a crispier fry. 

Slicing the potato into thin fries.

After the raw fries have soaked, remove them from the ice bath. Use a paper towel to pat them dry so that the water doesn’t pop with the hot, liquefied tallow.

Preheat a fire for medium-high heat (about 375F). Add a dutch oven or a deep cast iron skillet to the fire to preheat.

Add enough South Chicago Packing Beef Tallow to the dutch oven to be 1.5” high and heat up until 350F.

Frying the raw potatoes in the beef tallow.

Carefully add your thin cut fries to the hot oil to fry for only 2-3 minutes until golden brown. Do this in batches so as not to overcrowd the skillet.

Finally, pull the fries out and pat excess oil off until the fries are dry. Season with kosher salt and keep warm until serving.

Pro Tips

  • Make sure to have some paper towels handy before you cook the french fries so you’ll be ready to pat them dry when they come out. 
  • Don’t let your beef tallow exceed 400 degrees to avoid the smoke point.

Steak for the Frites:

Up next, let’s cook the steak.

Start by spraying your steaks with South Chicago Packing Beef Tallow Spray and generously season with a mixture of salt, pepper, and garlic powder. Then set them in the fridge until ready to cook.

Spraying the beef tallow onto the steaks and then seasoning them with salt, pepper and garlic.

Next,  kick the fire back up to a medium high heat (about 375 degrees F).

Add your steaks to the grill and cook for 3-4 minutes per side, checking with an instant-read thermometer until they are 120F. Once the steaks are done, pull off and let rest for 10 minutes. Finally, slice your bread in half and toast it up over the fire.

Once rested, slice up your filets and keep warm until it’s time for sandwich assembly.

Sandwich & Sauces:

While the steaks are resting, let’s make the beefonaise.

Add all your ingredients to a bowl for the Garlic Horseradish Beefonaisse and blend with an immersion blender until smooth. Set in the fridge until you’re ready to assemble the Steak Frites Sandwich serving.

For the sandwich, start with some of the Garlic Horseradish Beefonaisse, sliced steak, chimichurri, a large single layer of crispy fries, melted cheese and more beefonaisse on the top bun. Serve and enjoy!

How to Store Leftovers & Reheat

Keep your steak frites leftovers in an airtight container and microwave the steak and french fries to enjoy the leftovers for up to 3 days after cooking them. You could also throw the leftovers in the oven for a fresher, crispier result.

What to serve with Steak Frites Sandwiches

This heavy sandwich combines a main dish (steak) with a side (french fries). It’s best served alongside some veggies to balance out the meal. Try serving with a Caesar salad, steamed green beans, sauteed brussels sprouts, baked sweet potatoes, or another one of your favorite veggies and you’ll have a balanced plate!

Recipe FAQ’s

Can I use another cut of beef for this steak frites recipe?

While we used boneless strip steaks for our version of steak frites, yes, you can make this French bistro classic with other cuts of steak, like skirt steak, flank steak, rump steak, or hanger steak. Just make sure, no matter what cut of meat you choose, adjust the cooking times to make sure it gets cooked through properly to 120F, especially if you choose a thicker cut steak.

What kind of oil can I use for my fries?

In this recipe, we use beef tallow for the fries, which we believe is the tastiest option, and has a very high smoke point. Feel free to use vegetable oil, peanut oil, grapeseed oil, or olive oil, being mindful of the temperature to avoid their smoke point.

Can I use an air fryer for this recipe?

You can use your own frying method for this recipe if there’s something you prefer over cooking the fries in a large cast-iron skillet. An air fryer or deep fryer would both work well! No matter what method you use, make sure to keep the fries warm until you serve them.
