Ingredients You’ll Need
What makes these McDonald’s Philly Cheese Stack Loaded Fries so irresistible is the simple lineup of ingredients that come together in every cheesy, savory bite. Each component brings something unique to the table—crunch, creaminess, or a pop of vibrant color.
- Frozen French fries: These are the foundation for loaded fries—crispy and golden when baked to perfection.
- Olive oil: A splash for sautéing adds a subtle richness and helps caramelize the veggies.
- Onion: Thinly sliced for sweetness and a touch of classic cheesesteak flavor.
- Green bell pepper: Sliced and sautéed for a fresh, slightly tangy crunch.
- Thinly sliced steak: Ribeye or sirloin work best for tender, juicy bites that soak up all the seasonings.
- Garlic powder: Adds a savory depth to the steak and veggies.
- Salt: Essential for bringing out all the flavors in the dish.
- Black pepper: A gentle kick that balances the richness.
- Shredded mozzarella cheese: Melts beautifully for that stretchy, cheesy pull.
- Shredded cheddar cheese: Lends sharpness and extra creaminess to the cheese layer.
- Cheese sauce (optional): For those who want to go all-in on the ooey-gooey factor.
- Chopped parsley (optional): Adds a pop of color and a touch of freshness right before serving.
How to Make McDonald’s Philly Cheese Stack Loaded Fries
Step 1: Bake the Fries
Start by baking the frozen French fries according to the package instructions. You want them golden and crisp, since they’re the base that will hold up all those delicious toppings. While they’re crisping up in the oven, you can get everything else prepped!
Step 2: Sauté the Veggies
While the fries bake, heat olive oil in a skillet over medium heat. Add the sliced onion and green bell pepper, then let them cook down for about 6 to 8 minutes. The goal is to soften the veggies and bring out a little sweetness, with just a hint of caramelization for extra flavor.
Step 3: Cook the Steak
Push the sautéed veggies to one side of the skillet, then add your thinly sliced steak. Sprinkle with garlic powder, salt, and black pepper. Cook the steak for about 3 to 4 minutes, stirring occasionally, until it’s browned and just cooked through. The steak should stay tender—don’t overcook it!
Step 4: Assemble the Loaded Fries
Once your fries are done, spread them out on a large baking sheet or oven-safe dish. Layer the cooked steak evenly over the fries, then pile on the sautéed onions and peppers. Sprinkle the mozzarella and cheddar cheeses generously over the top, making sure every fry gets some love.
Step 5: Bake Until Melty
Pop the loaded fries back in the oven at 400°F for 5 to 7 minutes, or until the cheese is bubbly and melted to perfection. If you’re feeling extra indulgent, drizzle with cheese sauce as soon as they come out, and finish with a sprinkle of fresh parsley.
How to Serve McDonald’s Philly Cheese Stack Loaded Fries

Garnishes
A final flurry of chopped parsley adds a burst of color and a touch of freshness that balances all the rich, cheesy flavors. If you’re a fan of heat, a few sliced jalapeños or a pinch of crushed red pepper flakes can give your McDonald’s Philly Cheese Stack Loaded Fries a spicy kick!
Side Dishes
These loaded fries are pretty much a meal on their own, but they pair beautifully with a crisp green salad or a simple coleslaw for contrast. If you’re going all out, serve alongside classic diner fare like onion rings or chicken tenders for the ultimate feast.
Creative Ways to Present
Serve your McDonald’s Philly Cheese Stack Loaded Fries right on the baking tray for a rustic, shareable vibe. Or, dish them up in mini cast iron skillets for individual portions—perfect for parties! For game day, try loading them into paper boats, just like at your favorite fast food joint.
Make Ahead and Storage
Storing Leftovers
If you happen to have leftovers (which is rare!), let your loaded fries cool to room temperature before transferring them to an airtight container. They’ll keep in the fridge for up to 2 days, though the fries will soften a bit as they sit.
Freezing
While fries generally don’t love the freezer once they’ve been topped, you can freeze the steak, peppers, and onions separately for up to a month. Just prep fresh fries and assemble when you’re ready to enjoy McDonald’s Philly Cheese Stack Loaded Fries again.
Reheating
To reheat, spread leftovers on a baking sheet and warm them in a 400°F oven until hot and the cheese is bubbly again—this helps revive some crispiness. The microwave works in a pinch, but the fries will be a little softer.
FAQs
Can I use a different kind of cheese for these loaded fries?
Absolutely! Provolone or American cheese are both classic choices for a Philly cheesesteak vibe. Feel free to mix and match with your favorites for a unique twist on McDonald’s Philly Cheese Stack Loaded Fries.
What steak works best for this recipe?
Thinly sliced ribeye or sirloin are ideal for tenderness and flavor, but you can use any cut that cooks quickly. For a shortcut, try pre-sliced steak from the deli section.
Is there a vegetarian version of McDonald’s Philly Cheese Stack Loaded Fries?
Definitely! Swap the steak for sautéed mushrooms or a plant-based meat alternative. You’ll still get all the cheesy, savory goodness in every bite.
How do I keep the fries crispy after topping them?
Bake the fries until they’re extra golden before adding the toppings. When you return them to the oven, keep the bake time short—just until the cheese melts—to maintain crispiness.
Can I make this dish gluten-free?
Yes! Just use certified gluten-free fries and cheese sauce. The rest of the ingredients for McDonald’s Philly Cheese Stack Loaded Fries are naturally gluten-free.
