Ingredients You'll Need

A large, dark brown grilled steak with a slightly charred, textured surface takes the left side of a white round plate with subtle pattern. On the right side, there is a big pile of thin, golden-yellow fried potato sticks, some are light and others are darker, crispy. In front of the fries is a small round white bowl with a green rim holding a smooth, creamy white sauce. A fork and knife with wooden handles are placed to the left of the plate on a white marbled surface. The edge of a checkered cloth is visible on the lower right.

To create this mouthwatering Steak Frites with Truffle Aioli Recipe, you’ll only need a handful of simple, fresh ingredients. Each one plays a crucial role, from seasoning and texture to those subtle hints of flavor that make this dish so special.

  • 2 (1 ½-inch thick) boneless ribeye steaks: Choose well-marbled steaks for maximum juiciness and flavor.
  • Kosher salt: Essential for seasoning both the steak and fries, enhancing natural flavors.
  • Freshly ground black pepper: Adds the perfect kick and depth to the steak.
  • 1 pound russet potatoes, scrubbed: The ideal potato for fries because of their starchy, crispy texture.
  • 1 leek, white and light green part: Adds a subtle onion-like crunch when fried crisp.
  • Canola oil, for frying: Its neutral flavor and high smoke point are perfect for achieving that golden fry crispiness.

How to Make Steak Frites with Truffle Aioli Recipe

Step 1: Perfectly Roast Your Steaks

Start by preheating your oven to 250°F and generously seasoning the ribeye steaks with kosher salt and black pepper. Place them on a baking sheet fitted with a rack to allow air circulation and roast slowly until the internal temperature hits 125°F for a perfect medium-rare, which should take around 45 to 55 minutes. This gentle roasting locks in juices and flavors beautifully, setting the foundation for an unbeatable steak experience. Allow the steaks to rest for 5 minutes once out of the oven to let the juices redistribute.

Step 2: Sear for That Deep Golden Crust

Next, while the steak is resting, heat a cast iron skillet over medium-high heat until it’s smoking hot. This intense heat is crucial for getting that famed steak crust. Sear the steaks on each side for about 45 seconds or until a deeply golden color forms, then transfer to rest for another 10 minutes. This quick, hot sear seals in the roast’s tenderness and enhances the steak’s flavor with caramelized deliciousness.

Step 3: Slice Your Potatoes and Leeks

Using a mandoline slicer if you have one (or a steady hand with a knife), cut the russet potatoes into thin fries and julienne the white and light green parts of the leek lengthwise. The uniform thickness helps ensure even cooking and the julienned leeks will crisp up quickly in the hot oil for the perfect garnish.

Step 4: Fry the Fries to Crispy Perfection

Place the potato fries in a large dutch oven and add enough canola oil to cover them by about an inch. Heat over high heat until the oil reaches a boil, and cook the fries undisturbed for 15 minutes. Afterwards, gently stir with a slotted spoon to free any stuck fries, then continue frying for an additional 5 to 10 minutes until they turn irresistibly golden and crunchy. Remove the fries carefully and transfer them to a paper towel-lined baking sheet; immediately season with salt to finish.

Step 5: Crisp the Leeks

Drop the sliced leeks into the same hot oil and fry for 2 to 3 minutes until they achieve a golden, crispy texture. Remove them to the lined baking sheet alongside your fries and sprinkle with salt right away. These frizzle leeks add a delightful textural contrast and an aromatic punch to the dish.

Step 6: Plate and Serve

Now comes the fun part: plating! Lay each perfectly rested and seared steak on your plate, add a generous helping of your crispy fries, and top everything with those delicate frizzle leeks. Don’t forget the star of the show — a lavish dollop of truffle aioli on the side for dipping, elevating each bite to gourmet status. This approach to the famous Steak Frites with Truffle Aioli Recipe makes every bite a celebration.

Garnishes

To take your Steak Frites with Truffle Aioli Recipe to the next level, fresh herbs like finely chopped parsley or chives can be sprinkled on top for a pop of color and freshness. A light drizzle of extra virgin olive oil over the fries also adds shine and subtle richness without overpowering the truffle flavors.

Side Dishes

This dish pairs wonderfully with simple, crisp green salads dressed with lemon vinaigrette or grilled seasonal vegetables like asparagus or zucchini. These sides complement the richness of the ribeye and the earthy truffle aioli without competing for attention.

Creative Ways to Present

For a fun twist on presentation, arrange the steak and fries on a rustic wooden board and serve the truffle aioli in a mini cast iron skillet or small ramekin. You can also scatter extra fried leek pieces over the fries or even mix the fries with thinly shaved Parmesan for an additional flavor burst. Presentation is a chance to let your personality shine and make the meal feel extra special.

Make Ahead and Storage

Storing Leftovers

Leftovers from your Steak Frites with Truffle Aioli Recipe can be stored in airtight containers in the refrigerator for up to two days. Store the fries and steak separately to maintain optimal texture, as fries tend to lose crispness when refrigerated.

Freezing

While the steak is best enjoyed fresh for tenderness and juiciness, cooked fries can be frozen if you place them in a single layer on a baking sheet first, then transfer to freezer bags once solid. Unfortunately, the truffle aioli does not freeze well and may separate upon thawing.

Reheating

Reheat steak gently in a low oven or covered skillet to warm through without drying out, ideally at around 275°F until heated. For fries, reheat in a hot oven or air fryer to regain crispiness, avoiding the microwave, which can make fries soggy. Serve with freshly spooned truffle aioli for that iconic finishing touch.

FAQs

What is the best cut of steak for this recipe?

An excellent ribeye steak is ideal for Steak Frites with Truffle Aioli Recipe because of its marbling, which offers tremendous flavor and juicy tenderness when cooked to medium rare.

Can I substitute the leek frizzle with another garnish?

Absolutely! Thinly sliced and fried shallots or crispy fried onions are delicious alternatives that add a similar crunch and savoriness.

Is truffle aioli difficult to make at home?

Not at all! Truffle aioli is usually a simple blend of mayonnaise, truffle oil or truffle paste, garlic, lemon juice, and seasonings. It’s quick to whip up but instantly elevates this dish with rich, earthy flavor.

How do I achieve perfectly crispy fries every time?

The key is frying at the right temperature and cooking in two stages: a longer initial fry at a slightly lower heat to cook through, followed by a hotter finish to crisp the exterior. Drying potatoes well before frying also helps prevent sogginess.

Can this recipe be made for more than two people?

Definitely! Just scale up the ingredients accordingly, and consider cooking the fries in batches to maintain oil temperature and crispiness. The Steak Frites with Truffle Aioli Recipe is perfect for sharing at small dinner parties.

A classic French bistro dish featuring perfectly roasted and seared ribeye steaks served alongside crispy homemade steak fries and golden frizzled leeks, finished with a luxurious side of truffle aioli for dipping.

  • Total Time: 1 hour 10 minutes
  • Yield: 2 servings

Ingredients

Steak

  • 2 (1 ½-inch thick) boneless ribeye steaks
  • Kosher salt, to taste
  • Freshly ground black pepper, to taste

Fries and Leeks

  • 1 pound russet potatoes, scrubbed
  • 1 leek, white and light green parts only
  • Canola oil, for frying
  • Kosher salt, for seasoning

Truffle Aioli

  • Truffle aioli, for serving (store-bought or homemade)

Instructions

  1. Roast the Steak: Preheat your oven to 250°F. Season the ribeye steaks generously with kosher salt and freshly ground black pepper. Place them on a baking sheet fitted with a rack to allow even air circulation. Roast in the oven until an instant-read thermometer registers 125°F for medium-rare, which should take approximately 45 to 55 minutes. After roasting, let the steaks rest for 5 minutes to allow juices to redistribute.
  2. Sear the Steak: While the steaks rest, preheat a cast iron skillet over medium-high heat until it is smoking hot. Sear the steaks for about 45 seconds on each side until a deep golden crust forms. After searing, let the steaks rest for an additional 10 minutes before serving.
  3. Prepare Fries and Leeks: Using a mandoline slicer, carefully slice the potatoes into fries and julienne the leek lengthwise, ensuring thin, even strips for crispiness.
  4. Fry the Fries: In a large Dutch oven (4 to 5 quart), add the cut fries and cover with canola oil by about an inch. Place the pot over high heat and bring the oil to a boil. Cook the fries without stirring for 15 minutes, then use a slotted spoon to gently release any fries stuck to the bottom. Continue frying for another 5 to 10 minutes until the fries are crisp and golden brown. Remove fries with a slotted spoon and place them on a paper towel-lined baking sheet. Immediately season with kosher salt.
  5. Fry the Leeks: Carefully drop the julienned leeks into the hot oil. Fry for 2 to 3 minutes until they become golden and crispy. Transfer them to the same paper towel-lined baking sheet used for the fries and immediately season with kosher salt.
  6. Plate and Serve: Arrange each rested steak on a plate alongside a generous serving of crispy fries. Top the fries with the frizzled leeks. Serve with plenty of truffle aioli on the side for dipping and enjoy your classic Steak Frites experience.

Notes

  • For best results, use a meat thermometer to ensure perfectly cooked steak.

  • Leeks add a subtle onion flavor and a crunchy texture to the dish.
  • Truffle aioli can be purchased pre-made or prepared at home by mixing mayonnaise, truffle oil, garlic, and lemon juice.
  • Resting the steak after cooking helps retain its juices and improves tenderness.
