How to make Potato Corner Undercover Fries
Undercover Fries is essentially Potato Corner in disguise—it’s the same flavored French fry concept operating under a different name in certain U.S. locations.
Ingredients
For the Fries:
- 4 large potatoes (Russet potatoes work best for frying)
- Vegetable oil (or any high-heat frying oil such as canola or peanut oil)
- Salt (to season the fries after cooking)
For the Seasoning Mixes (Choose Your Favorite):
Cheese Powder Seasoning:
- 2 tbsp cheese powder (you can use a powdered cheese product like Kraft or cheddar cheese powder)
- 1 tsp garlic powder
- 1/2 tsp onion powder
- 1/2 tsp paprika (optional, for a smoky kick)
- 1/4 tsp salt (adjust to taste)
BBQ Seasoning:
- 1 tbsp paprika
- 2 tsp brown sugar
- 1 tsp garlic powder
- 1 tsp onion powder
- 1/2 tsp cumin (optional, for a smoky depth)
- 1/2 tsp chili powder
- 1/4 tsp salt
Sour Cream & Onion Seasoning:
- 2 tbsp sour cream powder (look for this in the spices or condiments section)
- 1 tsp onion powder
- 1/2 tsp garlic powder
- 1/4 tsp chives (dried or fresh, minced)
- 1/4 tsp salt
Spicy Chili BBQ Seasoning (Optional Extra):
- 1 tbsp BBQ seasoning (above)
- 1 tsp cayenne powder (adjust for heat)
Instructions
Step 1: Prepare the Potatoes
- Wash and peel the potatoes (optional—keeping the skin on adds extra texture).
- Slice the potatoes into thin, even sticks. Aim for a thickness of about 1/4 inch to ensure they cook evenly. You can also use a mandoline slicer if you have one.
- Place the potato sticks in a bowl of cold water and let them sit for at least 30 minutes (or up to an hour). This removes excess starch, making the fries crispier.
Step 2: Cook the Fries
- Drain the water and pat the fries completely dry using a clean kitchen towel or paper towels. Removing moisture is key for crispy fries!
- Heat the oil in a deep fryer or a heavy-bottomed pot. Use a thermometer to bring the oil to 325°F (163°C) for the first round of frying.
- Fry the potato strips in small batches for 3-4 minutes, turning them occasionally, until they are golden brown. They shouldn’t turn golden yet—this step cooks the inside. Remove the fries and set them on a wire rack or paper towels to drain excess oil.
- After all the batches are pre-fried, increase the oil temperature to 375°F (190°C). Fry the potato strips again for 2-3 minutes, or until they turn golden brown and crispy.
- Remove the fries and immediately sprinkle with a light dusting of salt.
Step 3: Prepare the Seasoning
- While the Potato Corner Undercover Fries are still hot, transfer them to a large bowl (preferably with a lid).
- Mix your chosen seasoning ingredients thoroughly in a small bowl.
- Sprinkle a generous amount of the seasoning (about 1-2 teaspoons depending on personal preference) over the fries while they’re in the bowl.
- Cover the bowl with its lid and shake vigorously to coat the fries evenly. Add more seasoning for a stronger flavor if desired.
Tips for Success
- Cutting Evenly: Uniform fry sizes ensure even cooking. Use a mandoline slicer or fry cutter for perfect consistency.
- Double-Fry Method: The first fry cooks the potatoes, while the second fry adds crispness to them. Don’t skip this step!
- Seasoning While Hot: Always toss the fries with the seasoning while they’re hot, as the seasoning will stick better this way.
- Homemade Cheese Powder: If you can’t find cheese powder, pulverize a mix of cheddar cheese and nutritional yeast in a food processor as a substitute.
- Fries Alternative: Feeling adventurous? Try the seasoning on tater tots, wedges, or sweet potato fries for variety.
What to serve with
Potato Corner Undercover Fries are iconic for their bold flavors and satisfying crunch, but they’re not meant to stand alone! While the seasoned fries are delicious on their own, pairing them with complementary side dishes, dips, drinks, and even main courses can elevate your meal experience.
1. Cheese Dip
A no-brainer for cheese fries or BBQ-flavored fries:
- Make a quick nacho cheese sauce with melted Velveeta cheese or cheddar, combined with milk and a splash of hot sauce.
- Add a bit of smoked paprika for a depth of flavor.
2. Garlic Aioli
Perfect for adding a creamy richness:
- Combine mayonnaise, garlic (grated or crushed), lemon juice, and a dash of olive oil.
- Add a touch of salt and pepper. It pairs particularly well with Sour Cream & Onion or BBQ fries.
3. Spicy Mayo
A great option for fries with a kick:
- Mix mayonnaise with sriracha or chili garlic sauce.
- Sweeten it slightly with a tiny drizzle of honey or brown sugar.
4. Sour Cream Chive Dip
Excellent with fries flavored with Sour Cream & Onion seasoning:
- Whisk sour cream with minced chives, lemon juice, and a bit of garlic powder.
- Bonus: Add a splash of buttermilk for a thinner, creamier texture.
5. Barbecue Sauce (or Spicy BBQ Sauce)
Works best with BBQ fries:
- Use store-bought barbecue sauce or make your own with ketchup, vinegar, brown sugar, and spices.
- Add a pinch of cayenne if you like it spicy!
Ingredients Substitutes
If you’re looking to recreate this dish at home, certain ingredients may need substitutions based on availability or dietary preferences. Here’s a guide on ingredient substitutes while maintaining the essence of the Potato Corner Undercover Fries:
1. Potatoes (Base Fries)
If you’re out of regular potatoes or want to experiment, here are some alternatives:
- Sweet Potatoes: A sweeter, slightly healthier alternative. They add a unique flavor to the Potato Corner Undercover Fries.
- Frozen Fries: Pre-cut frozen fries save time and come in various cuts like shoestring, steak fries, or crinkle-cut.
- Zucchini or Carrot Fries: For a lighter, veggie-based option, slice zucchini or carrots into thin strips and roast or fry them.
- Cassava/Taro: Creates a starchy, crispy fry similar to potato fries, common in Asian-style cooking.
- Jicama Fries: Low-carb option with a crunchy texture.
2. Flavoring Powders
Potato Corner is famous for its unique seasoning powders. To recreate these flavors at home or substitute for unavailable options, try the following:
Cheese Flavor:
- Substitute: Grated parmesan cheese mixed with powdered milk and a pinch of salt. Add paprika for a richer flavor.
- Alternative: Combine nutritional yeast (for vegans) with some cornstarch, garlic powder, and turmeric for that cheesy kick.
Barbecue Flavor:
- Substitute: Mix smoked paprika, brown sugar, cumin, garlic powder, onion powder, and chili powder. Adjust proportions for sweetness or spice.
- Alternative: Use premade barbecue rubs or seasonings typically available at grocery stores.
Sour Cream Flavor:
- Substitute: Combine powdered buttermilk (or powdered sour cream where available) with onion powder, garlic powder, and dried dill or chives.
- Alternative: Use ranch seasoning powder for a similar tangy, creamy taste.
Spicy Flavor (Chili):
- Substitute: Mix cayenne pepper, chili powder, garlic powder, and salt.
- Alternative: Add a touch of powdered hot sauce or a pinch of Korean chili flakes (gochugaru) for heat.
3. Oil for Frying
Oil plays a crucial role in crisping the fries. If you don’t have neutral-flavored oil, such as canola or vegetable oil, try these substitutes:
- Peanut Oil: High smoke point and adds a subtle nutty flavor.
- Avocado Oil: Great for frying due to its high smoke point, though pricier.
- Coconut Oil: Adds a mild sweetness but may alter the taste slightly.
- Air Fryer as an Alternative: Skip oil completely by air frying the fries for a health-conscious approach.
4. Optional Toppings
For added flair:
Cheese Sauce Substitute:
- Combine shredded cheddar cheese with cornstarch and heavy cream (or milk) over heat until smooth for a homemade version.
- Vegan alternative: Blend soaked cashews with nutritional yeast, garlic, olive oil, and a splash of almond milk for a creamy, cheesy flavor.
Herbs Substitute:
- Fresh parsley, chives, or dill can be used as a substitute for basil or other herbs.
Additional Spice Mix Substitute:
- Try taco seasoning, Cajun seasoning, or even Old Bay for a twist on flavors.
