The Juiciest Marinated Steak Ever with Perfect Cast-Iron Sear Tips, FAQ & printable recipe

Tips for success

To maximize the flavor penetration, use a fork to gently prick the surface of the flank steak all over before submerging it in the marinade. This creates tiny pathways for the liquid to enter the deeper muscle fibers.

Additionally, try to marinate the meat for at least four hours, or ideally overnight in the refrigerator. This extended time allows the marinade to fully work its magic, resulting in a significantly more tender and flavorful steak.

When searing the steak, resist the temptation to move it around in the pan. Let it sit undisturbed for the first few minutes to allow a proper crust to form.

Moving the steak too early can prevent the Maillard reaction from occurring efficiently and may cause the meat to tear. If the marinade contains sugars, watch the heat closely; if the crust begins to burn before the interior is cooked, slightly lower the heat to medium-high.

Variations

• Spicy Marinated Steak: Incorporate crushed red pepper flakes or a dash of hot sauce into the marinade for an extra kick of heat.
• Citrus Herb Steak: Mix fresh lime juice and chopped cilantro into the marinade to give the steak a bright, zesty finish.

Storage and make-ahead

Fridge

Store leftovers in an airtight container in the refrigerator for up to 3 to 4 days, cooling within 2 hours of cooking.

Freezer

Freeze cooked steak in a freezer-safe bag for up to 3 months. Thaw in the refrigerator overnight before reheating.

Reheat

Reheat gently in a skillet over medium-low heat with a splash of beef broth or water to prevent the meat from drying out.

Any leftover steak must be cooled to room temperature for no more than two hours before being stored. Place the leftover slices or whole pieces into an airtight container or wrap them tightly in heavy-duty aluminum foil. Store the cooked steak in the refrigerator, where it will keep well for up to three to four days. For longer storage, the steak can be frozen, though it is best enjoyed fresh to preserve its tender texture.

This recipe is excellent for make-ahead meal prep. You can place the steak in the marinade and freeze it immediately. As the meat thaws in the refrigerator overnight, it will marinate simultaneously, saving you valuable prep time on the day you plan to cook. Simply thaw completely, drain, and sear according to the recipe instructions.

Serving ideas

For the best presentation and texture, slice the flank steak thinly at a forty-five-degree angle. This angled cut maximizes the surface area of each slice, showcasing the beautiful pink interior and making the meat even more tender to chew.

Arrange the slices overlapping on a warm serving platter, and pour any juices that accumulated on the cutting board back over the meat to enhance its glossiness and flavor. Serve immediately while still warm.

This versatile steak pairs wonderfully with a variety of side dishes. For a classic steakhouse feel, serve it alongside roasted garlic mashed potatoes and grilled asparagus.

It also makes an exceptional protein addition to fresh green salads, warm grain bowls, or tucked into warm tortillas with fresh salsa for quick steak tacos. The bold, savory flavor of the marinade complements both hearty comfort foods and light, refreshing sides beautifully.

Ingredients

• 2 lb flank steak
• 1 cup steak marinade

Instructions

1. Place the flank steak in a shallow dish or a large resealable plastic bag. Pour the steak marinade over the meat, ensuring it is completely coated. Cover or seal the bag tightly, then place it in the refrigerator to marinate for at least 4 hours or overnight to allow the flavors to penetrate.
2. Remove the marinated flank steak from the refrigerator 30 minutes before cooking to take the chill off, which helps it cook more evenly. Discard the excess marinade. Heat a heavy cast-iron skillet or grill pan over high heat until it is smoking hot.
3. Carefully place the flank steak in the hot skillet. Sear without moving for 4 to 5 minutes, allowing a deep, dark crust to form. Flip the steak using tongs and sear the other side for an additional 4 to 5 minutes.
4. Insert an instant-read thermometer into the thickest part of the steak to verify it has reached an internal temperature of 145°F (63°C). Immediately transfer the steak to a clean cutting board and let the meat rest at least 3 minutes before slicing to allow the juices to redistribute.
5. Using a sharp carving knife, slice the rested flank steak thinly across the grain at a forty-five-degree angle. Arrange the slices on a warm serving platter, spooning any juices from the cutting board over the top.
