Disco Fries
intro
Crispy golden fries smothered in rich brown gravy and stretchy melted mozzarella, the iconic New Jersey diner comfort food made for sharing.
Ingredients
Steps
Prep the potato fries
Scrub 900g Russet potatoes, leave skins on for traditional texture (peel if preferred), and cut into uniform 1cm (3/8-inch) thick sticks. Submerge cut fries in a bowl of cold water for 20 minutes to leach out excess starch, which guarantees a crisp final texture. Drain fully and pat completely dry with paper towels or a clean lint-free kitchen towel to prevent dangerous oil splatter and soggy fries.
Par-cook the fries
Heat 1L neutral vegetable oil in a deep, heavy-bottomed Dutch oven to 160°C (325°F) over medium heat. Fry the dried potato sticks in 3 equal small batches (to avoid dropping oil temperature) for 3 minutes per batch; fries will be pale, tender, and not crisp at this par-cook stage. Use a slotted spoon to transfer par-fried fries to a wire rack set over a rimmed baking sheet to drain for 5 minutes.
Warm the brown gravy
While par-fried fries rest, pour 473ml (2 cups) brown beef gravy into a small stainless steel saucepan over medium-low heat. Stir in ½ tsp (2g) freshly ground black pepper, and simmer gently for 4-5 minutes until fully heated through, stirring occasionally to prevent sticking to the pan bottom. Turn heat to the lowest setting to keep gravy warm, avoiding a rapid boil which will over-thicken the gravy.
Crisp the fries
Increase the oil temperature to 190°C (375°F) over medium-high heat. Working again in 3 small batches, return par-cooked fries to the hot oil and fry for 2-3 minutes per batch, until fries are deep golden brown with a shatteringly crisp outer crust. Transfer finished fries back to the wire rack, and immediately season all sides evenly with 1 tsp (5g) kosher salt while the surface is still hot and oil-coated to help salt adhere.
Melt the mozzarella
Arrange the hot, salted fries in an even layer in a 23cm (9-inch) oven-safe cast iron skillet or serving dish. Sprinkle all 340g (1.5 packed cups) shredded low-moisture mozzarella evenly over the top of the fries. Place the skillet under a preheated high broiler (260°C/500°F) for 60-90 seconds, watching constantly, until cheese is fully melted, smooth, and just starting to bubble at the edges.
Add gravy and serve
Remove the skillet from the broiler, and pour the warm brown gravy evenly over the cheese-covered fries, letting the gravy seep down between the fry layers. Let the dish rest for 1 minute to let the heat from the gravy fully meld with the melted cheese, then serve immediately while hot, with extra black pepper on the side for guests who want more seasoning.
Tips
2.Do not overcrowd the frying pot when cooking fries, as this drops the oil temperature sharply and results in greasy, limp fries; cook in 3 small, even batches to get a shatteringly crisp outer crust.
3.For authentic New Jersey diner flavor, skip the cheese curds used in Canadian poutine; add a tiny pinch of garlic powder to the warm gravy for extra savoriness if desired.

OMG I grew up on these after late nights at the Jersey Shore boardwalk and this recipe is SPOT ON! The cheese pull is insane, the gravy is perfectly savory, not too salty. Made these for movie night with my roommates last night and every single fry was gone in 10 minutes. Total game changer, no more sad takeout disco fries for us!
Made these for my teen son’s birthday sleepover and the kids went WILD. I added a little extra shredded mozzarella on top like the tip said and it was chef’s kiss. Super easy even for a weeknight when I’m running between soccer practice and homework help, will 100% be adding this to our regular rotation!
Wait, I’ve never even heard of disco fries before seeing this recipe? I thought poutine was the only gravy and cheese fry dish out there! Tried these last night and wow, the lack of curds is totally made up for by that thick, melty American cheese. Only knock is I over-salted my first batch of gravy because I was heavy handed with the shaker, but that was totally my mistake, not the recipe’s. SO good.
Brought these to my office potluck last week and I had people begging me for the recipe before I even left the break room! I prepped the gravy ahead of time on Sunday and just baked the fries right before I headed in, which made assembly so quick. Only note is I wish I’d made a double batch, it was gone in 15 minutes flat!
Made these after my late shift at the hospital last night and it hit so much better than the fast food I usually grab on my way home. Cook time was way shorter than I expected too, I didn’t even have to wait forever for the fries to crisp up. 10/10 comfort food.
So happy this recipe is easy to adapt for gluten free! I swapped the regular flour in the gravy for GF all purpose and used my go-to frozen GF fries, and you couldn’t even tell the difference. Perfect comfort food for when my celiac acts up and I need something cozy.
I’ve been going to the same NJ diner since I was a kid and order disco fries every single time, and this recipe tastes exactly like what they serve. The trick of melting the cheese under the broiler for a minute at the end? *Chef’s kiss* No sad, unmelted cheese slices here. I’ll never pay diner prices for these again!
Wait, can you freeze these? I’m trying to stock my freezer with quick comfort food meals for busy school nights, and these look like they’d be a hit with my kids. I made a test batch last night and they were amazing, I just wish there was a make-ahead freezer tip in the official recipe notes! Any tips if I make a big batch ahead?
Made these in my tiny dorm air fryer last night and they came out perfect! I used frozen crinkle cut fries, air fried them for 18 minutes, made the quick gravy on my hot plate, and layered the cheese on while everything was still hot. My roommate and I ate the whole plate while we studied for midterms, zero regrets.
Made these as a side for my weekend cookout and they were way more popular than the burgers and hot dogs! I added a little dash of hot sauce to the gravy for a tiny kick and everyone was raving. Super easy to throw together while the grill was going, will definitely be a cookout staple from now on.
I’m literally just learning to cook and this was the first recipe I didn’t mess up! The instructions are so straightforward, no weird fancy ingredients I had to run to three stores to find. My boyfriend thought I ordered takeout, I was so proud of myself.
Made these for the Eagles watch party last Sunday and let’s just say I’m being required to bring them to every single game for the rest of the season. I used a mix of mozzarella and American cheese like someone suggested in the tips and the cheese pull was so good people were taking videos of it. Absolute banger of a recipe.
I was having the worst rainy day last week and decided to make these on a whim, and it instantly turned my whole mood around. There’s something about crispy fries, savory gravy, and melty cheese that just fixes everything. I ate the whole pan while I watched old rom coms, no shame.
As someone who’s been vegetarian for 5 years, I was so happy I could swap the beef gravy for mushroom gravy and still get that classic disco fry vibe! The mushroom gravy was so rich and umami, my meat-eating roommate even said she preferred it to the beef version. Great base recipe to customize.
