How to Cook a Flank Steak in a Crock-Pot?
Flank steak can absolutely be cooked in a crock-pot! The key is to pair it with a flavorful marinade and cook it low and slow for tender, juicy results – contrary to popular belief, a crock-pot can transform this typically grilled cut into a melt-in-your-mouth delight.
Understanding Flank Steak and Slow Cooking
Flank steak, known for its rich, beefy flavor and relatively lean profile, is often reserved for quick cooking methods like grilling or searing. Its inherent toughness can be challenging if overcooked. However, the extended, gentle cooking process of a slow cooker can break down these tough fibers, resulting in a surprisingly tender and delicious meal. This technique allows the flank steak to absorb maximum flavor from marinades and cooking liquids, creating a complex and satisfying dish.
Benefits of Cooking Flank Steak in a Crock-Pot
There are numerous advantages to slow cooking flank steak:
- Tenderization: The low and slow method tenderizes the steak, making it easier to chew and enjoy.
- Flavor Infusion: The extended cooking time allows the steak to absorb the flavors of the marinade and other ingredients.
- Convenience: Once assembled, the crock-pot requires minimal attention, freeing you up for other tasks.
- Cost-Effectiveness: You can often find flank steak at a more affordable price compared to other cuts that are traditionally used for slow cooking.
- Ideal for Meal Prep: The cooked steak can be shredded and used in various dishes throughout the week.
Essential Ingredients and Equipment
To successfully cook flank steak in a crock-pot, you’ll need:
- Flank Steak: 2-3 pounds, trimmed of excess fat.
- Marinade Ingredients: Typically includes soy sauce, Worcestershire sauce, olive oil, garlic, onion, herbs, and spices. Specific recipes vary.
- Vegetables (Optional): Onions, bell peppers, mushrooms, etc., can be added to the crock-pot for extra flavor and nutrients.
- Liquid: Beef broth, water, or even a dark beer can be used to help keep the steak moist during cooking.
- Crock-Pot: A 6-quart or larger slow cooker is recommended.
- Measuring Cups and Spoons: For accurate ingredient measurement.
- Mixing Bowl: To prepare the marinade.
Step-by-Step Guide to Crock-Pot Flank Steak
Here’s a detailed breakdown of the cooking process:
- Prepare the Marinade: Whisk together all marinade ingredients in a mixing bowl. Taste and adjust seasonings as needed.
- Marinate the Steak: Place the flank steak in a resealable plastic bag or a shallow dish. Pour the marinade over the steak, ensuring it is well coated. Marinate for at least 4 hours, or preferably overnight, in the refrigerator.
- Prepare the Crock-Pot: Lightly spray the inside of the crock-pot with cooking spray.
- Layer Ingredients: Place chopped onions and other desired vegetables in the bottom of the crock-pot.
- Place the Steak: Remove the steak from the marinade and place it on top of the vegetables. Pour the remaining marinade over the steak. Add beef broth, water, or beer if needed, so that the liquid reaches approximately halfway up the side of the steak.
- Cook: Cover the crock-pot and cook on low for 6-8 hours, or on high for 3-4 hours. The steak is done when it is easily shredded with a fork.
- Shred and Serve: Remove the steak from the crock-pot and shred it with two forks. Return the shredded steak to the crock-pot to soak up the juices. Serve warm, with your choice of sides.
Common Mistakes to Avoid
- Overcooking: Flank steak can become dry and tough if overcooked, even in a slow cooker. Monitor the cooking time and check for tenderness.
- Using Too Much Liquid: Adding too much liquid can result in a bland flavor. Only add enough liquid to reach halfway up the side of the steak.
- Skipping the Marinade: Marinating is crucial for tenderizing and flavoring the steak. Don’t skip this step!
- Not Trimming Excess Fat: While some fat is desirable, too much can make the dish greasy. Trim off any large pieces of fat before cooking.

Do I need to sear the flank steak before putting it in the crock-pot?
