Recipe Information

• Prep Time: 10 minutes
• Cook Time: 2–5 hours
• Total Time: About 3 hours
• Servings: 6–8 servings

Ingredients

• 1 bag frozen crinkle-cut french fries (28–32 ounces)
  Crinkle-cut fries work perfectly because their ridges hold onto the creamy cheese sauce beautifully. Using frozen fries also eliminates peeling, slicing, and frying.
• 1 can condensed cream of onion soup (10.5 ounces)
  This creates the creamy base of the dish while delivering rich onion flavor throughout every bite.
• 1 cup shredded sharp cheddar cheese, divided
  Sharp cheddar provides bold cheesy flavor and melts into a creamy, irresistible topping.
• 1 packet dry onion soup mix (1 ounce)
  The onion soup mix boosts savory flavor and gives the fries their delicious diner-style taste.

Step-By-Step Instructions

1. Prepare the Slow Cooker
   Lightly spray the inside of a 4- to 6-quart slow cooker with nonstick cooking spray. This helps prevent sticking and makes cleanup easier.
2. Add the Frozen Fries
   Pour the frozen crinkle-cut fries directly into the bottom of the slow cooker. Spread them into an even layer for consistent cooking.
3. Mix the Onion Sauce
   In a medium bowl, whisk together the condensed cream of onion soup and the dry onion soup mix until fully combined.
4. Coat the Fries
   Pour the onion mixture evenly over the fries. Use a spoon or spatula to gently spread the mixture around so most of the fries are lightly coated.
5. Add the Cheese
   Sprinkle 3/4 cup of the shredded cheddar cheese over the fries. Reserve the remaining cheese for the final topping.
6. Cook Slowly
   Cover the slow cooker with the lid and cook:
   • HIGH: 2–3 hours
   • LOW: 4–5 hours
   Cook until the fries are tender and the mixture is bubbling around the edges.
7. Finish with Cheese
   Sprinkle the remaining cheddar cheese over the top. Cover again and let sit for 5–10 minutes until melted.
8. Serve Warm
   Gently scoop from the bottom when serving to mix the creamy sauce with the fries. Keep the slow cooker on the warm setting during parties and gatherings.

Pro Tips for Perfect Cheesy Fries

• Do not thaw the fries before cooking or they may become mushy.
• Use freshly shredded cheese for smoother melting.
• Avoid over-stirring to keep the fries from breaking apart.
• Add smoked paprika or garlic powder for extra flavor.
• Watch cooking time carefully since slow cookers can vary.
