Steak Frites with Herb Mustard: A French Classic with a Twist

Steak Frites, one of the most iconic dishes in French cuisine, is a simple yet elegant combination of seared steak and crispy fries. Though its origins are deeply rooted in bistros and brasseries across France and Belgium, Steak Frites has gained global popularity for its comforting, satisfying nature. The version of Steak Frites with Herb Mustard not only stays true to its French roots but also introduces a subtle twist with a mustard-based herb sauce, adding a delightful layer of complexity to the dish. This article explores the history of the dish, its key components, cooking techniques, variations, and health benefits. By the end, you’ll understand why this meal has stood the test of time and how you can recreate it at home.

The History of Steak Frites

The origins of Steak Frites are somewhat debated, with both France and Belgium claiming the dish as their own. In France, the term “frites” refers to fries, which are traditionally paired with a variety of grilled or pan-seared meats, particularly steak. This dish became a staple of French bistro culture in the early 20th century.

In Belgium, fries hold a special place in the culinary landscape, often served alongside meats like steak or moules (mussels). Some Belgian food historians argue that frites (or fries) originated in Belgium, where potatoes were fried as an alternative to fish when rivers froze over during winter. Despite these competing claims, what is indisputable is that Steak Frites became an iconic European dish, found in eateries from casual brasseries to fine dining restaurants.

Key Components of Steak Frites with Herb Mustard

At its heart, Steak Frites is a dish built on the balance between two primary components: the steak and the fries. However, the herb mustard sauce in this version brings an additional element that elevates the flavors and makes it unique.

  • The Steak:
    Flank steak, used in this recipe, is a flavorful cut of beef that is lean and tender when cooked properly. It is known for its strong beefy flavor and fibrous texture, which benefits from marinating or pairing with robust sauces. In this recipe, the steak is seared to perfection in a cast-iron skillet, allowing the exterior to caramelize beautifully while the interior remains juicy and tender.
  • The Fries:
    Traditional French fries, or frites, are a crucial component of this dish. Instead of deep-frying, this version opts for oven-baked russet potato fries, which not only make the dish healthier but also provide a crunchy, golden texture. The fries are seasoned with paprika and cayenne pepper, giving them a mild kick, while egg whites help create that coveted crispiness without the need for excessive oil.
  • Herb Mustard Sauce:
    The herb mustard sauce is the star of this variation. It combines the tangy sharpness of Dijon mustard with the fresh, vibrant flavors of chives and tarragon. The sauce ties the entire dish together, adding a zesty element to balance the richness of the steak and the savory fries.

Techniques for Perfect Steak Frites

  • Searing the Steak:
    Searing is essential for achieving a delicious crust on the steak. A cast-iron skillet is recommended for this purpose because it retains heat well and provides even cooking. The key is to preheat the skillet until it is extremely hot before adding the steak. This will ensure a proper sear that locks in the juices, keeping the steak moist and flavorful.
  • Resting the Meat:
    Resting the steak after cooking is crucial. This allows the juices to redistribute throughout the meat, resulting in a more tender and juicy steak. Cutting into the steak too early can cause the juices to run out, leaving the meat dry. In this recipe, the steak is left to rest in the pan for about 5-8 minutes after searing.
  • Achieving Crispy Fries:
    Achieving perfectly crispy fries without deep-frying is possible with the right techniques. Patting the potatoes dry before coating them in egg whites and seasoning ensures that they bake evenly and become crisp. Spacing the fries on the baking sheet and spraying them with olive oil cooking spray also prevents sogginess and promotes browning.

Variations of Steak Frites

While this version of Steak Frites features herb mustard sauce and oven-baked fries, there are many ways to customize and adapt the dish to suit individual preferences. Here are a few variations:

  • Sauce Options:
    Instead of herb mustard, classic French Steak Frites is often served with sauces like béarnaise or peppercorn. Béarnaise sauce is a rich, buttery sauce flavored with tarragon and vinegar, while peppercorn sauce brings a creamy, spicy element to the dish. For a simpler approach, a drizzle of garlic butter over the steak works wonders.
  • Alternative Cuts of Steak:
    Though flank steak is used in this recipe, other cuts of beef work equally well. Ribeye, sirloin, and filet mignon are popular choices for Steak Frites. Ribeye offers a richer, fattier texture, while filet mignon provides a more delicate and tender bite.
  • Vegetarian or Vegan Versions:
    For those looking for a meat-free version, Steak Frites can be easily adapted. Portobello mushrooms or cauliflower steaks are excellent substitutes for the beef, providing a hearty, umami-rich alternative. Vegan fries can also be made by swapping the egg whites with cornstarch for extra crispiness.

Health Benefits of Steak Frites with Herb Mustard

Though Steak Frites is often viewed as an indulgent meal, this particular version offers several health-conscious tweaks without sacrificing flavor.

  • Oven-Baked Fries:
    By opting for oven-baked fries instead of deep-fried ones, this recipe significantly reduces the fat and calorie content. Olive oil cooking spray and egg whites are used to achieve crispy fries without excessive oil, making them a healthier alternative.
  • Lean Protein:
    Flank steak is a relatively lean cut of beef, providing ample protein without too much fat. It is also rich in essential nutrients like iron, zinc, and B vitamins, which support energy levels and overall health.
  • Herbs and Mustard:
    Fresh herbs like chives and tarragon add flavor without the need for extra salt or fat. Dijon mustard, known for its pungent and tangy flavor, is low in calories and offers antioxidants that may support heart health.

Serving Suggestions for Steak Frites with Herb Mustard

  • Wine Pairing:
    Steak Frites is commonly paired with red wine. A medium-bodied red wine like Pinot Noir or a more robust Bordeaux complements the flavors of the beef without overpowering the dish. The acidity in the wine balances the richness of the meat and fries, while also enhancing the herbal notes of the mustard sauce.
  • Side Dishes:
    Though the fries serve as the primary side in Steak Frites, additional sides can elevate the meal further. A simple mixed green salad with vinaigrette or a side of sautéed spinach can provide freshness and balance. Alternatively, roasted vegetables like asparagus or green beans make excellent accompaniments.

Conclusion

Steak Frites with Herb Mustard is a perfect example of how a classic dish can be transformed with just a few thoughtful additions. The combination of perfectly seared steak, crispy fries, and tangy herb mustard sauce makes for a meal that is both comforting and elegant. The dish’s simplicity allows it to be a versatile choice, whether you’re preparing it for a special occasion or just a casual weeknight dinner.
