Flank Steak Recipe Oven: Tender Slices With Herb-Crusted Perfection

This oven-baked method transforms tough flank steak into tender, juicy slices with minimal effort.

By using high heat and a flavorful herb crust, you’ll achieve perfect results every time without firing up the grill.

Ingredients for Flank Steak Recipe Oven

A few quality ingredients create that perfect herb-crusted oven-baked flank steak with minimal effort.

The flank steak quality is paramount. Look for well-marbled pieces at Whole Foods or Costco—avoid anything with excessive connective tissue. The fresh herbs should be vibrant and aromatic; if they don’t smell like much when crushed, they won’t contribute much flavor. For the Dijon, Maille or Grey Poupon are reliable brands. The olive oil should be robust enough to stand up to the bold herb flavors.

No fresh rosemary? Dried works at one-third the amount, though the texture will differ slightly. Swap thyme for marjoram or oregano if needed. For a non-alcoholic deglaze, beef broth with a splash of vinegar mimics the wine’s acidity. If avoiding dairy, olive oil can replace the butter for finishing, though the flavor profile will be slightly different.

Prep the herb crust just before baking for maximum freshness. The cooked steak keeps 3-4 days in the fridge, though it’s best served immediately. For leftovers, thinly slice against the grain and reheat gently in a skillet with a splash of broth to restore moisture.

Step-by-Step Instructions for Flank Steak in the Oven

Achieve restaurant-quality results with this method that guarantees a perfectly tender steak every time.

Step 1: Prepare the Herb Crust

In a small bowl, combine the 2 tbsp fresh rosemary, 2 tbsp fresh thyme leaves, 4 cloves minced garlic, 1 tbsp Dijon mustard, 1 tbsp balsamic vinegar, 1.5 tsp kosher salt, 1 tsp black pepper, and 1 tsp smoked paprika. The mustard acts as a binder to help the herbs adhere to the meat.

This herb mixture creates a flavorful crust that complements the natural richness of the 1.5 lb flank steak. I finely chop the rosemary to ensure even distribution and prevent any woody texture. The smoked paprika adds a subtle depth that pairs beautifully with the beef’s robust flavor.

Step 2: Sear and Season the Steak

Pat the 1.5 lb flank steak dry with paper towels to ensure a good sear. Heat 2 tbsp olive oil in a large oven-safe skillet over medium-high heat until it shimmers. Sear the steak for 2-3 minutes per side until deeply browned—this creates a flavorful crust and locks in juices.

Remove the skillet from heat and brush the herb mixture evenly over both sides of the steak, pressing gently to ensure it adheres. The searing step is crucial for developing complex flavors, while the herb crust will infuse the meat with aromatic notes during the oven finish.

Step 3: Finish in the Oven

Place the skillet with the steak in a preheated 400°F oven. Roast for 8-10 minutes for medium-rare, or until the internal temperature reaches 130-135°F. The exact time depends on the thickness of your steak, so I recommend using a meat thermometer for accuracy.

For a perfectly even cook, flip the steak halfway through the roasting time. The high oven temperature ensures a quick cook that maintains the steak’s natural tenderness while allowing the herb crust to caramelize slightly.

Step 4: Rest and Deglaze

Transfer the steak to a cutting board and tent loosely with foil. Let it rest for 10 minutes—this allows the juices to redistribute, ensuring every slice is moist and flavorful. Meanwhile, place the skillet back on the stovetop over medium heat.

Add the 0.25 cup red wine to the skillet and scrape up any browned bits from the bottom. Let it simmer for 2-3 minutes until reduced by half, then whisk in the 1 tbsp unsalted butter for a glossy finish. This quick pan sauce captures all the concentrated flavors from the cooking process.

Step 5: Slice and Serve

Slice the steak thinly against the grain for maximum tenderness. The grain runs lengthwise along the steak, so cut perpendicular to these fibers. This shortens the muscle fibers, making each bite easier to chew.

Drizzle the red wine sauce over the slices and serve immediately. The sauce should pool slightly around the meat, adding moisture and an extra layer of flavor. For the best experience, serve with sides that can soak up the delicious pan juices.

Serving Suggestions for This Dish

Plating Techniques

Fan the sliced steak across the plate in an overlapping pattern, creating an elegant presentation. Drizzle the red wine sauce in a zigzag pattern over the meat for visual appeal. Garnish with fresh thyme sprigs for a pop of color. 💫

Side Pairings

Serve with creamy mashed potatoes to soak up the sauce—2 cups of Yukon Golds work perfectly. Roasted asparagus (1 lb at 400°F for 12 minutes) adds a crisp contrast. A simple arugula salad with lemon vinaigrette cuts through the richness beautifully.

Bread Options

Warm crusty bread or garlic bread is ideal for mopping up every last bit of sauce. I love using a baguette sliced and toasted with olive oil and garlic. The bread’s crunch complements the steak’s tenderness perfectly.

Wine Pairing

A bold Cabernet Sauvignon or Malbec stands up to the herb crust and beefy flavors. For white wine lovers, a full-bodied Chardonnay with oak notes works surprisingly well. Serve slightly chilled for reds, or at cellar temperature.

Garnish Ideas

Sprinkle with flaky sea salt and freshly cracked black pepper just before serving. A few balsamic-glazed pearl onions add sweetness and acidity. Fresh parsley provides a bright, herbaceous finish that ties the dish together.
