How to Make Beer-Marinated French Fries: Ingredients and Step-by-Step Recipe

This post is also available in: Español Português Français

French fries are probably the most popular way of cooking this tuber native to the Americas, one of the four main food crops in the world.

The origin of this way of cooking is still contested, because Belgium, France and Chile’s Araucanía region all claim to have invented it. Belgium turned fries into a national emblem, with a museum of its own in the city of Bruges (Frietmuseum), which makes this beer-marinated recipe an excellent chance to bring together a little of the best of both cultures.

French fries are eaten all over the world under different shapes and names, such as “pommes frites” in French or “patatas fritas” in Spanish.

Beer-Marinated French Fries Recipe

Prep time: 2 hours 30 minutes
Cook time: 20 minutes
Servings: 6

This recipe calls for a Pale Ale, but it is well worth experimenting with different styles until you find the one that best suits your palate.

Ingredients

2 kg (4.4 lb) potatoes
1 liter (about 34 fl oz) Pale Ale
4 tablespoons mayonnaise
4 tablespoons ketchup
1 tablespoon rum
½ tablespoon cayenne pepper
Oil for frying
Sea salt

Instructions

Peel the potatoes and cut them into sticks, rinse them in cold water and dry them with paper towels or a clean kitchen cloth. Place the potatoes in a large bowl and add enough beer to cover them, cover the bowl with plastic wrap and marinate in the refrigerator for 2 hours.
In a medium bowl, combine the mayonnaise, ketchup, two teaspoons of beer or to taste, the cayenne pepper and the rum, stirring and adjusting until you get a sauce with a creamy consistency.
Pour plenty of oil into a deep frying pan or fryer and heat it to 160°C (320°F), checking the temperature with a frying thermometer or an infrared thermometer.
Drain the potatoes and dry them very well, because the liquid makes hot oil spatter. Carefully add the potatoes without overcrowding them and fry for about 5 minutes or until lightly golden, repeating as many times as needed. Remove with a slotted spoon and place on paper towels, sprinkling with a little sea salt.
Raise the oil temperature to 180°C (356°F) and fry the potatoes again for about 2 to 3 minutes or until well browned, then remove, drain on paper towels and adjust the salt.
Serve the fries immediately, optionally garnished with cayenne pepper and with the dipping sauce on the side, for example alongside chicken wings or homemade burgers.

International French Fry Day

International French Fry Day is celebrated every year on August 20 as a tribute to one of the most popular and beloved dishes in the world.

Although no specific historical event gave rise to this celebration, French fries are an iconic food loved in many cultures, which makes them worthy of a special day of their own.

What Is the Difference Between Marinating and Macerating?

Marinating is mainly used to tenderize, season and flavor food. The acidity of the marinade helps break down the fibers of meat or fish, tenderizing them in the process. The ingredients in the marinade also infuse the food with flavor.

The aim of maceration is to soften food, enhance its natural flavors and draw out its juices. It is used especially with fruit and is often part of preparing desserts and drinks.

What happens in this recipe is marinating, even though it is often called macerating. Beer has a mild acidity, so these two hours mainly allow the surface of the potato to pick up some flavor before it reaches the oil.

French Fries in an Air Fryer

Fried food tends to be an enemy of healthy eating, which is why cutting down on fat is one of the keys to a balanced diet.

If you still don’t want to give up crispy fries or tasty croquettes, there is an alternative in air fryers, a type of fryer that uses currents of very hot air to cook and brown food without the need for oil.

Frequently Asked Questions (FAQ)

1. Which beer is best for marinating French fries?

This recipe uses a Pale Ale because it adds flavor without a dominant bitterness. You can also try other styles, although a very hoppy beer may leave a more bitter finish.

2. Why are the potatoes fried twice?

The first fry, at 160°C (320°F), cooks the inside without too much browning. The second, at 180°C (356°F), browns the surface and gives the fries their crunch.
