What Makes These Vegetarian Disco Fries Special
Disco fries got their name in the ’70s when partygoers across New Jersey would head to 24-hour diners after the clubs closed. So yeah, drunk food.
The dish is often compared to Canada’s poutine, but instead of cheese curds and brown beef gravy, disco fries typically use melty mozzarella cheese and a smoother sauce.
This vegetarian version swaps the traditional beef stock-based sauce for a hearty, mushroom-based gravy made with all-purpose flour, onions, and umami-boosting ingredients like miso, soy sauce, and Worcestershire (veg-friendly, of course!). It’s rich without being heavy and tastes just as satisfying—if not more.
You can use homemade fries or frozen crinkle-cut fries. Use meltable cheese—white cheddar or mozzarella are good options.

Instructions
Prep the Potatoes (Fresh)
If using fresh potatoes, scrub and cut into 1/3-inch sticks. Soak in cold water for 20–30 minutes, then drain and dry thoroughly.
Bake the potatoes
Toss fresh potatoes (or frozen fries) with oil, salt, and pepper.
Spread on a parchment-lined baking sheet and bake at 425°F (220°C) for 35–45 minutes, flipping halfway.
For air-frying, cook at 390°F (200°C) for 18–22 minutes in batches, shaking halfway through. If using frozen fries, follow package instructions and cook until extra crispy.
Keep cooked fries warm while you make the gravy.
make the gravy
In a skillet, melt butter over medium heat. Add sliced onion and a pinch of salt. Cook 6–8 minutes until golden and softened.
Stir in chopped mushrooms and cook 6–8 minutes until moisture evaporates. Add minced garlic and cook 30 seconds more.
Sprinkle flour over the mixture. Stir and cook for 1–2 minutes.
Gradually whisk in vegetable broth. Stir in soy sauce, Worcestershire, miso (if using), and thyme. Simmer 8–10 minutes until thickened.
Add vinegar. Taste and adjust salt, pepper, or soy sauce as needed.
Assemble and broil
Pile hot fries onto a baking sheet or oven-safe dish. Spoon hot gravy on fries. Top with shredded cheese. Broil 1–3 minutes until cheese is bubbly.
serve
Sprinkle with parsley or chives and serve immediately with extra gravy on the side.
Why This Dish Works
Unlike heavy gravies made with beef broth, this one is lighter but still bold. The mushroom base delivers fiber, minerals, and big flavor, while using the oven or air fryer keeps the dish lighter than deep-fried options.
Plus, the whole vibe is just fun. It’s the kind of comfort food that pairs with classic disco hits, a queer disco community potluck, or just a cozy solo night in.
Variations to Try
Southern Disco Fries Use a veggie Country Ham Gravy with smoky paprika and a touch of Dijon mustard.
Spicy Kick Add hot sauce or Montreal steak seasoning to the gravy and top with jalapeños.
Vegan Use vegan butter and vegan cheese. Choose a fully plant-based Worcestershire or swap in extra soy sauce.
Truffle Touch Add a few drops of truffle oil to finish.
Extra Protein Top with roasted chickpeas or crisped
Tips to Keep it Crisp
- Soak and dry fresh-cut fries well to prevent sogginess.
- Don’t skip the roux step or you’ll get floury gravy.
- Add gravy and cheese while fries are hot—the heat helps the cheese melt into gooey perfection.

FAQ
Can I use store-bought gravy?
Sure! Just check the label for vegetarian ingredients. Add mushrooms, miso, or soy sauce to deepen the flavor.
Can I make this ahead for a party?
The fries won’t hold up well if you make those ahead of time but you can definitely make the gravy in advance. Cook the fries and then assemble them right before serving to get the best textrure. This will ensure you’re fries don’t taste stale or soggy.
What’s the Best cheese to use for vegetarian disco fries?
Since vegetarians typically do consume some dairy, you can use low-moisture mozzarella. Blending with sharp cheddar gives it a better flavor. If you’re keeping it strictly vegan, vegan cheese works well too. Just avoid super wet cheeses as they can make everything soggy.
how long does the gravy last?
4-5 days in the fridge. You can freeze the gravy for up to 2 months.
