Flank steak, a lean and flavorful cut of beef, is often overlooked in favor of more popular cuts like ribeye or sirloin. However, when cooked low and slow, flank steak can be transformed into a tender and deliciously flavorful dish that’s sure to impress even the most discerning palates. In this article, we’ll explore the art of slow cooking flank steak in the oven, and provide you with a step-by-step guide to achieving perfection.
Understanding Flank Steak
Before we dive into the cooking process, it’s essential to understand the characteristics of flank steak. This cut of beef comes from the belly of the cow, near the hind legs, and is known for its:
- Lean protein content: Flank steak is relatively low in fat, making it a popular choice for health-conscious cooks.
- Coarse texture: The muscle fibers in flank steak are longer and more coarse than those found in other cuts of beef, which can make it more challenging to cook.
- Robust flavor: Flank steak has a bold, beefy flavor that’s enhanced by its high concentration of umami taste receptors.
Choosing the Right Cut of Flank Steak
When selecting a flank steak, look for the following characteristics:
- Thickness: Opt for a steak that’s at least 1-1.5 inches thick, as this will allow for more even cooking.
- Marbling: While flank steak is naturally lean, look for a cut with some marbling (fat distribution) throughout, as this will add flavor and tenderness.
- Color: Choose a steak with a rich, red color, as this indicates a higher concentration of myoglobin, which contributes to the meat’s flavor and texture.
Preparing the Flank Steak for Slow Cooking
Before slow cooking your flank steak, it’s essential to prepare it properly. Here are the steps to follow:
Trimming and Seasoning
- Trim excess fat: Use a sharp knife to trim any excess fat from the steak, taking care not to cut too deeply into the meat.
- Season the steak: Rub the steak all over with a mixture of salt, pepper, and your desired herbs and spices. For a classic flavor combination, try using a blend of garlic powder, paprika, and thyme.
Bringing the Steak to Room Temperature
- Remove the steak from the refrigerator: Take the steak out of the refrigerator and let it sit at room temperature for at least 30 minutes before cooking.
- Pat dry the steak: Use paper towels to gently pat the steak dry, removing any excess moisture from the surface.
Slow Cooking the Flank Steak in the Oven
Now that your flank steak is prepared, it’s time to slow cook it to perfection. Here’s a step-by-step guide to slow cooking flank steak in the oven:
Preheating the Oven
- Preheat the oven to 300°F (150°C): This low temperature will allow for slow and even cooking, breaking down the connective tissues in the meat and resulting in a tender, fall-apart texture.
Wrapping the Steak in Foil
- Wrap the steak in foil: Place the steak in the center of a large piece of aluminum foil, leaving enough room to fold the foil over the steak and create a tight seal.
- Add aromatics: Place your desired aromatics, such as sliced onions, carrots, and celery, on top of the steak before wrapping it in foil.
Cooking the Steak
- Place the steak in the oven: Put the wrapped steak in the preheated oven and cook for 2-3 hours, or until the internal temperature reaches 130°F (54°C) for medium-rare.
- Baste the steak: Every 30 minutes, baste the steak with the juices that have accumulated in the foil, using a spoon or brush to distribute the liquid evenly.
Resting the Steak
- Remove the steak from the oven: Once the steak has reached your desired level of doneness, remove it from the oven and let it rest for 10-15 minutes.
- Unwrap the steak: Carefully unwrap the steak, taking care not to spill the juices that have accumulated in the foil.
Slicing and Serving the Flank Steak
Once the steak has rested, it’s time to slice and serve. Here are a few tips to keep in mind:
Slicing Against the Grain
- Slice the steak against the grain: Use a sharp knife to slice the steak against the grain, cutting in a smooth, even motion.
- Slice to desired thickness: Slice the steak to your desired thickness, taking care not to cut too thinly, as this can result in a less tender final product.
Serving Suggestions
- Serve with your favorite sides: Serve the slow-cooked flank steak with your favorite sides, such as roasted vegetables, mashed potatoes, or a fresh salad.
- Add a sauce or marinade: Consider adding a sauce or marinade to the steak, such as a classic Béarnaise or a tangy chimichurri.
| Cooking Time | Internal Temperature | Level of Doneness |
|---|---|---|
| 2-3 hours | 130°F (54°C) | Medium-rare |
| 3-4 hours | 140°F (60°C) | Medium |
| 4-5 hours | 150°F (65°C) | Medium-well |
| 5-6 hours | 160°F (71°C) | Well-done |
By following these steps and guidelines, you’ll be able to slow cook a deliciously tender and flavorful flank steak in the oven. Remember to always use a meat thermometer to ensure the steak has reached a safe internal temperature, and don’t be afraid to experiment with different seasonings and sauces to find your perfect flavor combination. Happy cooking!
