This isn't just a typical copycat recipe, it's the real burger-flippin' deal. These fries don't taste "kind of like" McDonald's French fries, they taste EXACTLY like McDonald's fries. The secret has to do with the seasoning they get doused in after they are fried, and luckily, it's nothing you can't easily procure. Here's how to make a batch of authentic McDonald's French Fries.

Ingredients:

For Frozen Fries:
3 pounds of russet potatoes
8 cups water
2 TBL white vinegar
4 pinches of salt
Peanut oil, for frying
No-stick spray, as needed

McFlavor Dust:
4 TBL table salt
2 TBL MSG
1/2 tsp black pepper
1/4 tsp onion powder
2 tsp raw popcorn kernels, optional

For Frozen Fries: Peel and slice potatoes using a potato press using a 3/8 inch die. Place potatoes in a bowl of water to prevent browning. Place 8 cups of water in a 4-quart dutch oven and bring to a boil. Add vinegar and salt.

Cook two handfuls of potatoes at a time for 8 minutes. Don't crowd the pan! Drain potatoes on a towel-lined sheet pan. Allow to cool completely, at least an hour. Once cool, place potatoes in a bowl.

Drain the water out of the Dutch oven and fill it up 1/3 of the way with peanut oil. Bring to 350 degrees Fahrenheit. Fry potatoes one handful at a time for 90 seconds. Place on a sheet pan that you greased with no-stick spray. Repeat with the rest of the potatoes. Allow to cool, and then place the pan in the freezer overnight.

The next day, mix the potatoes up to break them apart from each other. Then, place them in zip-top bags, I dose them out in 6 oz. Servings. Place these bags in the freezer until ready to use.

For McFlacvor Dust: Place all ingredients in a small seasoning shaker. Mix to combine. You can also add a small number of raw popcorn kernels to keep it from clumping.

To Make McDonald's Fries, Deep Fry Method: Bring the same pot of oil to 350 degrees. Cook fries straight from the freezer for 90 seconds per 6 ounce serving. Drain on paper towels, place in a large bowl and sprinkle with seasoning. Toss to coat, and serve immedietly.

To Make McDonald's Fries, Air-Fried Method: Air-Fryers vary, but I place frozen fries on my air frying rack and slide it into my countertop oven and cook them as hot as the oven will go. In my case, it's 480 degrees with the convection fan on. It takes about five minutes for me, but it can take as much as 10 depending on your device. Place fries in bowl, season, toss, and serve.

MSG is sold in many grocery stores as "Accent." You can find it in the spice aisle. Or, you can buy a bunch on Amazon here: https://amzn.to/3I70fnz
