1 teaspoon garlic powder

1 teaspoon onion powder

1 teaspoon smoked paprika

1 teaspoon salt

½ teaspoon black pepper

½ teaspoon dried parsley

Green Peppercorn Sauce

2 tablespoons unsalted butter

1 small shallot, finely diced

2 garlic cloves, minced

1 tablespoon green peppercorns (drained if packed in brine), lightly crushed

1 teaspoon Dijon mustard

½ cup beef broth

¾ cup heavy cream

¼ cup grated Parmesan cheese (optional for extra richness)

½ teaspoon Worcestershire sauce

Salt and black pepper to taste

Garnish

Fresh parsley, chopped

Extra crushed green peppercorns

Fresh thyme (optional)

Parmesan shavings (optional)

Equipment Needed

Air fryer

Large bowl

Sharp knife

Saucepan

Tongs

Paper towels

Instructions

Step 1: Prepare the Potatoes

Wash and scrub the potatoes thoroughly.

Leave the skins on for extra texture and flavor, or peel them if preferred.

Cut each potato into thick steak fry wedges, about ¾-inch wide.

Place the fries in a bowl of cold water and soak for 30 minutes to remove excess starch. This helps create crispier fries.

Drain and pat the potatoes completely dry with paper towels.

Step 2: Season the Fries

Transfer the dried potato wedges to a large bowl.

Add:

Olive oil

Garlic powder

Onion powder

Smoked paprika

Salt

Black pepper

Dried parsley

Toss until every fry is evenly coated.

Step 3: Preheat the Air Fryer

Preheat the air fryer to 380°F (193°C) for 3–5 minutes.

Lightly spray the basket with cooking oil.

Step 4: Air Fry the Steak Fries

Arrange the fries in a single layer in the air fryer basket.

Cook in batches if necessary to avoid overcrowding.

Air fry for 15 minutes.

Shake the basket or flip the fries.

Continue cooking for another 13–17 minutes, or until the fries are deep golden brown and crispy.

For extra crispiness, increase the temperature to 400°F (200°C) during the final 2–3 minutes.

Transfer the fries to a serving platter.

Step 5: Make the Green Peppercorn Sauce

While the fries cook, melt the butter in a saucepan over medium heat.

Add the diced shallot and cook for 2–3 minutes until softened.

Stir in the minced garlic and cook for another 30 seconds.

Add the crushed green peppercorns and Dijon mustard, stirring well.

Pour in the beef broth and Worcestershire sauce.

Simmer for 3–4 minutes, allowing the liquid to reduce slightly.

Reduce the heat to low and stir in the heavy cream.

If using, add the Parmesan cheese and stir until melted.

Simmer gently for another 3–5 minutes, stirring frequently, until the sauce thickens enough to coat the back of a spoon.

Taste and adjust the seasoning with salt and black pepper.

Step 6: Serve

Arrange the crispy steak fries on a serving plate.

Serve the warm green peppercorn sauce in a small bowl for dipping or drizzle it over the fries.

Garnish with chopped parsley, a few crushed green peppercorns, fresh thyme, or Parmesan shavings.

Serve immediately while hot.

Pro Tips

Soaking the potatoes removes excess starch and helps produce crispier fries.

Dry the potatoes thoroughly before seasoning.

Don’t overcrowd the air fryer basket—cook in batches if needed.

Use Russet potatoes for the fluffiest interior.

Stir the sauce frequently to prevent the cream from scorching.

Freshly crushed green peppercorns provide the best flavor.

Frequently Asked Questions

Can I use frozen steak fries?

Yes. Frozen steak fries work well in the air fryer. Cook them according to the package instructions and prepare the green peppercorn sauce separately.

What are green peppercorns?

Green peppercorns are unripe pepper berries with a milder, fresher flavor than black peppercorns. They are commonly sold in brine or freeze-dried and are often used in classic steakhouse sauces.

Can I make the sauce ahead of time?

Yes. Prepare the sauce up to one day in advance and refrigerate it in an airtight container. Reheat gently over low heat, adding a splash of cream or beef broth if it becomes too thick.

Can I make this recipe vegetarian?

Absolutely. Replace the beef broth with vegetable broth and omit the Worcestershire sauce or use a vegetarian version. The sauce will still be creamy and flavorful.
