The Perfect Cut – Choosing and Preparing Flank Steak for the Garlic Butter Skillet Oven Recipe

When it comes to making the best Garlic Butter Skillet Flank Steak Oven Recipe, selecting the right cut of beef is crucial. Flank steak is a lean, flavorful, and budget-friendly option, but its texture requires proper handling to ensure tenderness.

Why Flank Steak Works Best

Flank steak comes from the lower abdominal muscles of the cow, which means it’s naturally tough but packed with deep beefy flavor. Unlike tenderloin or ribeye, flank steak has long muscle fibers, making it ideal for:

• Quick cooking methods (searing, grilling, broiling)

• Marinating (to enhance tenderness)

• Slicing thinly against the grain (to maximize tenderness)

How to Choose the Best Flank Steak

1. Look for Even Thickness – Avoid uneven cuts, as they cook unevenly.

2. Bright Red Color – Indicates freshness.

3. Good Marbling – While lean, some fat streaks improve flavor.

4. No Excessive Liquid in Packaging – Too much moisture means lower quality.

Preparing Flank Steak for Cooking

To ensure maximum tenderness and flavor, follow these steps:

1. Pat Dry & Season Well

• Remove excess moisture with paper towels (helps with searing).

• Generously season with kosher salt and black pepper (at least 30 minutes before cooking for deeper flavor penetration).

2. Cutting for Even Cooking

• Divide into 4 equal portions (helps with even searing and oven finishing).

• Score lightly (optional) – Make shallow diagonal cuts to help tenderize.

3. Bringing to Room Temperature

• Let steak sit for 20-30 minutes before cooking (prevents uneven cooking).

Common Mistakes to Avoid

❌ Overcooking – Flank steak turns tough and chewy past medium-rare.
❌ Slicing with the Grain – Always cut against the grain for tenderness.
❌ Skipping the Resting Step – Resting allows juices to redistribute.

By properly selecting and prepping your flank steak, you’ll set the foundation for a perfectly tender and flavorful Garlic Butter Skillet Flank Steak Oven Recipe.

 Mastering the Sear – How to Cook Flank Steak Perfectly in a Skillet & Oven

The secret to a restaurant-quality Garlic Butter Skillet Flank Steak Oven Recipe lies in the sear-to-oven method, which locks in juices while ensuring even doneness.

Why Use a Cast-Iron Skillet?

• Retains heat for a perfect crust.

• Goes from stovetop to oven seamlessly.

• Creates fond (browned bits) for a flavorful pan sauce.

Step-by-Step Searing Process

1. Preheat the Skillet Properly

• Heat vegetable oil (or another high-smoke-point oil) until shimmering hot.

• A properly heated skillet should lightly smoke before adding steak.

2. Add Butter for Flavor

• After oil, add 1 tbsp butter for richness (it will brown quickly, adding nutty depth).

3. Sear the Steak

• Place steak in the pan without overcrowding (work in batches if needed).

• Press lightly to ensure full contact with the pan.

• 3 minutes per side for a deep brown crust.

Finishing in the Oven

• Transfer skillet to a 400°F oven for 3 minutes (for medium-rare, 125°F internal temp).

• Use a meat thermometer for precision (flank steak overcooks easily).

Pro Tips for the Best Sear

🔥 Dry the Steak Thoroughly – Moisture prevents browning.
🔥 Don’t Move the Steak Too Soon – Let it develop a crust before flipping.
🔥 Baste with Butter – Spoon melted butter over steak while searing for extra flavor.

By mastering the sear-and-oven method, you’ll achieve a juicy, caramelized, and perfectly cooked flank steak every time.
