But when you elevate that humble base with thinly sliced, savory steak and a generous drizzle of gooey melted cheese, you enter the territory of culinary indulgence.

1. Ingredients and Tools Needed

Before you start cooking, it’s essential to gather all your ingredients and equipment. Using high-quality ingredients makes a noticeable difference in this dish, particularly with the steak and cheese.

Ingredients:

For the Fries:

• 4–5 large Russet potatoes (or 1.5 lbs frozen French fries, if preferred)

• Vegetable oil (for frying or brushing, depending on cooking method)

• Salt, to taste

• Optional: Paprika, garlic powder, or black pepper for seasoning

For the Steak:

• 1 lb ribeye steak (or sirloin as a more affordable alternative)

• 1 tbsp olive oil or butter

• Salt and freshly ground black pepper

• 1 medium yellow onion, thinly sliced

• Optional: green bell peppers or mushrooms, thinly sliced

For the Cheese Sauce:

• 2 tbsp unsalted butter

• 2 tbsp all-purpose flour

• 1 cup whole milk (warm)

• 1½ cups shredded provolone cheese (or a blend of provolone and American cheese)

• Salt, to taste

• Optional: ¼ tsp garlic powder or Dijon mustard for added flavor

Optional Garnishes:

• Chopped parsley

• Sliced pickled jalapeños

• Crushed red pepper flakes

Tools:

• Cast iron or heavy-bottomed skillet

• Medium saucepan (for cheese sauce)

• Large baking sheet or air fryer (if not deep frying)

• Tongs or spatula

• Sharp knife and cutting board

• Grater (if grating cheese yourself)

• Meat thermometer (optional, for precise steak doneness)

• Paper towels (for draining fries)

2. Preparing the Fries

The fries form the foundation of this dish, and they need to be crispy enough to support the weight of steak and cheese. You can use either homemade or store-bought fries. Here’s how to make them from scratch:

Option 1: Homemade Fries (Deep Fried or Oven Baked)

Step 1: Wash and Cut the Potatoes

• Wash your russet potatoes thoroughly, especially if you’re keeping the skin on.

• Cut them into even matchsticks or steak fries, about ¼ to ½ inch thick.

• Soak the fries in cold water for at least 30 minutes (up to overnight) to remove excess starch. This helps them crisp better when cooked.

Step 2: Dry and Preheat

• Drain the soaked potatoes and pat them dry thoroughly with paper towels.

• If baking, preheat your oven to 425°F (220°C) or preheat your air fryer.

Step 3A: Deep Fry Method

• Heat vegetable oil in a deep fryer or heavy pot to 325°F (163°C).

• Fry the potatoes in small batches for 4–5 minutes until pale and soft (this is the first fry).

• Remove and drain on paper towels. Increase oil temp to 375°F (190°C), then refry for 2–3 minutes until golden brown and crispy.

• Drain again, season with salt immediately.

Step 3B: Oven-Baked Method

• Spread dried potato strips on a parchment-lined baking sheet.

• Toss with oil, salt, and optional seasonings (like paprika).

• Bake for 30–35 minutes, flipping halfway through, until golden and crisp.

Step 3C: Air Fryer Method

• Toss the fries in a small amount of oil and seasoning.

• Air fry at 400°F (204°C) for 18–20 minutes, shaking the basket halfway through.

Option 2: Using Frozen Fries

• Follow the package instructions, either baking or air frying until crisp.

• Season after cooking for best results.

3. Preparing the Steak

The steak is the centerpiece of this dish, and proper cooking ensures flavor and tenderness.

Step 1: Freeze the Steak Slightly for Easier Slicing

• Place your steak in the freezer for 20–30 minutes before slicing. This firms it up and makes it easier to cut thin slices.

Step 2: Slice the Steak Thin

• Using a sharp knife, slice the steak against the grain into very thin strips. The thinner, the better—it should almost melt in your mouth when cooked.

Step 3: Sauté the Onions (and Optional Veggies)

• Heat 1 tablespoon of oil or butter in a skillet over medium heat.

• Add sliced onions (and optional peppers or mushrooms).

• Cook until caramelized and softened, about 8–10 minutes. Remove and set aside.

Step 4: Cook the Steak

• In the same pan, increase heat to high.

• Add a little oil and the sliced steak. Season with salt and pepper.

• Sear quickly for 1–2 minutes, tossing occasionally. Do not overcook—it should stay tender and juicy.

• Return the onions to the pan and mix to combine. Remove from heat.

Note: You can also cook steak in larger slices or steak tips and then chop or shred them after cooking, depending on your preferred texture.

4. Making the Cheese Sauce

This creamy, flavorful cheese sauce ties everything together.

Step 1: Make a Roux

• In a medium saucepan over medium heat, melt 2 tablespoons of butter.

• Add the flour and whisk continuously for about 1 minute to form a light roux. Don’t let it brown.

Step 2: Add Milk

• Slowly whisk in the warm milk. Keep whisking until smooth and thickened, about 3–4 minutes.

Step 3: Add Cheese

• Lower the heat. Gradually add shredded cheese, whisking constantly until melted and velvety.

• Season with a pinch of salt, garlic powder, or a dash of mustard for extra flavor.

Tip: For extra creamy sauce, stir in a tablespoon of cream cheese or a splash of evaporated milk.
