It takes less than 10 minutes to make Cheese Sauce for fries at home! You’ll end up with the perfect cheese fries, drizzled in our rich, creamy cheddar cheese sauce!
Is there anything sadder than a french fry without any sauce? I mean…I’ll still eat the plain fries, but I’m going to complain about it the whole time.
I’m not sure I can settle for just ketchup or mayo any more either. Now we whip up fry sauce or homemade honey mustard for fries.
And I’m certainly not drizzling a jar of cheese sauce over my fries if I have a craving for cheese fries. Not when my homemade cheese sauce is so dang easy to make.
This cheese sauce for fries is going to be a staple in your house! Not only is it (obviously) good on fries, it’s also great drizzled over broccoli or other veggies, it’s easy to make, and reheats well.

Flour – We’re using all-purpose flour to thicken up our cheese sauce.
Milk & Butter – We’ll make a roux by whisking together the flour and butter and then slowly whisking in the milk until the sauce thickens.
Seasoning – To add a depth of flavor to the sauce you’ll mix in garlic powder, onion powder, and ground mustard.
Cheddar Cheese – You will need a cheese grater and a block of good quality cheddar! Freshly grated will make for a much more flavorful and creamy cheese sauce.
We’ve found the flavor of medium cheddar to be our favorite, but you may use mild for a less intense flavor or sharp for a stronger flavor.
Hot Sauce – We prefer Frank’s Red Hot. The hot sauce does not make this sauce at all spicy. It just adds a little flavor boost.

How To Make Cheese Sauce For Fries:

Flour & Butter: Melt the butter in a small saucepan and whisk in the flour. You’ll want to let this cook, stirring constantly, for a minute or two.
Milk: Pour the milk into the flour mixture and whisk constantly until it has thickened up to a gravy like consistency. Next whisk in the garlic powder, onion powder, and ground mustard!
Finish: Remove the saucepan from the heat. Add a handful of cheese at a time to the still hot pan, stirring each time until the cheese has melted and is smooth. Stir in the hot sauce.
HELPFUL TIP!
No More Grainy Cheese Sauce!
Remove the pan from the heat before adding the grated cheddar to the sauce. This will prevent your cheese sauce from getting gritty and grainy. If the roux isn’t hot enough to melt the cheese, turn the heat back on for just long enough to melt the cheese, stirring constantly. Overcooking the sauce will make it grainy.
KARLY’S TIPS & TRICKS!
Consistency: You can add a splash or two of milk to the cheese sauce to reach your desired consistency. Keep in mind the sauce will also thicken up the more that it cools!
Flavor: Not a fan of cheddar? You can really make cheese sauce with loads of different cheeses, such as havarti, gouda, or pepperjack.
Nacho Cheese: Want to drizzle this homemade cheese sauce over tortilla chips? Add a bit of chili powder and extra hot sauce to your sauce!

INGREDIENTS
- 1 tablespoon butter
- 1 tablespoon flour
- ½ cup whole milk plus 2-3 tablespoons as needed
- 1 teaspoon garlic powder
- ½ teaspoon onion powder
- ½ teaspoon ground mustard
- 4 ounces medium cheddar cheese freshly shredded
- 1 teaspoon hot sauce such as Frank’s
INSTRUCTIONS
- Add the butter to a small saucepan over medium heat and melt. Whisk in the flour to form a paste and cook for 1-2 minutes, stirring often to avoid burning.
- Add ½ cup of milk to the flour mixture and whisk constantly until the mixture has thickened up to the consistency of a gravy. Whisk in the garlic powder, onion powder, and mustard powder.
- Remove the pan from the heat and add the shredded cheese one handful at a time, stirring with each handful, until smooth and melted.
- If necessary, return the pan to low heat to completely melt the cheese, but do not cook the cheese sauce for longer than necessary or it may become grainy. Add milk one tablespoon at a time to reach your desired thickness, keeping in mind the sauce will thicken the more it cools.
- Stir in the hot sauce and serve warm.
