Detailed Recipe Steps

Now that you have gathered all your ingredients and utensils, let’s walk through the steps to make the Sage-Crusted Flat Iron Steak with Lemon-Parmesan Matchstick Fries and Savory Peppercorn Jus.

Step 1: Prepare the Steak

Preheat: Start by preheating your grill or cast-iron skillet over medium-high heat. Getting the pan hot is crucial for achieving a perfect sear.
Season: In a small bowl, mix the finely chopped sage with the olive oil. Use this mixture to rub all over the flat iron steaks, ensuring they are evenly coated. Season generously with salt and freshly ground black pepper for added flavor.
Cook: Place the steaks on the hot grill or skillet. Cook for about 4-5 minutes per side for medium-rare doneness, adjusting the cooking time based on your preferred level of doneness.
Rest: Once cooked, remove the steaks from the heat and let them rest for about 5 minutes. Resting helps the juices redistribute, making for a more tender steak.

Step 2: Make the Matchstick Fries

Preheat Oven: While the steak is resting, preheat your oven to 425°F (220°C). A hot oven is essential for crispy fries.
Prepare Potatoes: Wash and peel the russet potatoes. Using a sharp knife, cut them into thin matchstick shapes to ensure they cook evenly.
Toss: In a mixing bowl, toss the matchstick potatoes with olive oil, lemon zest, and salt until they are evenly coated. The lemon zest adds a wonderful brightness to the fries.
Bake: Spread the fries in a single layer on a baking sheet. Bake in the preheated oven for 20-25 minutes, flipping halfway through to ensure they cook evenly and become crispy.
Finish: Once golden and crispy, remove the fries from the oven and immediately sprinkle with grated Parmesan cheese for added flavor.

Step 3: Prepare the Peppercorn Jus

Combine Ingredients: In a saucepan over medium heat, combine the beef broth and whole black peppercorns. Bring to a simmer and allow it to reduce slightly for about 5-7 minutes.
Whisk: Once reduced, whisk in the Dijon mustard and unsalted butter. This will create a rich and creamy jus. Season with salt to taste.
Strain (Optional): If you prefer a smooth sauce, strain the jus to remove the peppercorns before serving.

Step 4: Serve

Slicing the Steak: After the steak has rested, slice it against the grain into thin strips. This will ensure each bite is tender and easy to chew.
Plate: Serve the sliced steak alongside the lemon-Parmesan matchstick fries. A drizzle of the savory peppercorn jus over the steak adds a gourmet touch.
Enjoy: Dig in and savor the incredible flavors of your homemade dish!

Tips and Variations

To elevate your cooking experience and adapt the recipe to your preferences, consider these tips and variations:

Alternative Steaks: If flat iron steak isn’t available, you can substitute it with flank steak or sirloin. Both alternatives will yield great results.
Vegetarian Option: For a vegetarian version, replace the steak with grilled portobello mushrooms seasoned with sage. The mushrooms can absorb the flavors beautifully.
Fries Variations: Try adding spices like smoked paprika or garlic powder to the fries for an extra kick. You can also experiment with different cheeses, like Asiago or Pecorino, instead of Parmesan.
Gluten-Free Adaptation: This recipe is already gluten-free as it does not include any flour-based ingredients. However, ensure that your beef broth is gluten-free if you have a sensitivity.
Avoid Common Mistakes: Ensure the skillet or grill is hot enough before adding the steak to achieve a good sear. Don’t overcrowd the pan; cook in batches if necessary to avoid steaming the meat.
Leftovers: Store any leftover steak and fries in an airtight container in the refrigerator for up to 3 days. Reheat in the oven to maintain crispiness.
