Ingredients Needed for Slow Cooker Flank Steak

To start, let’s gather our ingredients. Here’s what you’ll need to make a simple yet rich slow cooker flank steak that’s bursting with flavor.

Ingredients	Quantity
Flank steak	1.5 – 2 pounds
Beef broth	2 cups
Soy sauce	1/4 cup
Garlic cloves	4-5, minced
Onion	1 large, sliced
Olive oil	1 tablespoon
Salt and pepper	To taste
Optional: Carrots, bell peppers, potatoes	As desired

Key Points:

• Choose a high-quality flank steak: Look for a cut with good marbling, as it will result in a juicier, more tender final dish.
• Beef broth forms the base, adding depth and richness.
• Aromatics like garlic and onions provide natural sweetness and a savory base.
• Optional add-ins: Adding vegetables like carrots or potatoes gives you a complete meal in one pot.

Preparing the Flank Steak for Slow Cooking

Now that you have your ingredients ready, it’s time to prep the steak.

Selecting the Best Flank Steak

Start by choosing the right flank steak. Opt for a piece that’s fresh and has a good amount of marbling. This will give you that melt-in-your-mouth tenderness that slow-cooked dishes are known for. Local butcher shops or quality grocery stores often have the best options.

Seasoning the Steak

For seasoning, simplicity is key. Sprinkle your flank steak with salt, pepper, garlic powder, and paprika for a boost in flavor. You can even rub in the spices a few hours before cooking to let the flavors seep in.

• List of Suggested Seasonings:
  • Salt and pepper
  • Garlic powder
  • Paprika (optional for a smoky touch)
  • Any fresh herbs you prefer, like thyme or rosemary

Searing the Steak for Maximum Flavor (Optional)

While not required, searing the flank steak in a skillet with a little olive oil before placing it in the slow cooker can make a big difference. The caramelization from searing locks in the flavors and adds a deeper, richer taste to your finished dish.

Tip: Sear for about 2-3 minutes per side over medium-high heat, just until you see a nice brown crust.

Slow Cooker Setup and Layering

Choosing the Right Slow Cooker Settings

Setting up your slow cooker is a breeze, but choosing the correct settings will ensure a perfectly cooked meal. For flank steak, the low-and-slow method is ideal. Cook on the low setting for about 7-8 hours or high for about 4 hours, depending on how much time you have.

Layering Ingredients for Flavor Infusion

Start by placing the sliced onions and minced garlic at the bottom of the slow cooker. This layer provides a foundation of flavor and prevents the meat from sticking. Add the seared flank steak on top, then pour in the beef broth and soy sauce, which will slowly infuse the meat with flavor as it cooks.

Cooking Times and Temperature Guide for Perfect Flank Steak

Slow Cooker Setting	Cooking Time
Low	7-8 hours
High	3-4 hours

Note: Cooking flank steak on the low setting allows the connective tissues to break down fully, giving you a tender and juicy result. For a slightly firmer texture, you may prefer a shorter cook time on high.

Adding Vegetables for a Complete Meal

Want to make it a one-pot meal? Adding vegetables can be a great option.

Timing Vegetables for Perfect Texture

Since vegetables like carrots, potatoes, and bell peppers have different cooking times, add them at the right point in the cooking process.

• Add hearty vegetables like carrots and potatoes about 2 hours before the end of the cooking time.
• Bell peppers and other softer veggies can go in during the last hour for best results.

Seasoning Vegetables for Enhanced Flavor

Season the vegetables lightly with salt and pepper before adding them to the slow cooker. If you want an additional layer of flavor, toss them in olive oil and your choice of herbs for a burst of freshness.

Final Steps: Thickening the Sauce & Serving Suggestions

How to Thicken the Sauce

If you’d like a thicker sauce, try one of these methods:

1. Cornstarch Slurry: Mix 1 tablespoon of cornstarch with 2 tablespoons of water, then stir into the slow cooker during the last 30 minutes.
2. Reduction Method: Pour the cooking liquid into a saucepan and simmer until it reaches your desired consistency.

Serving Ideas for Slow Cooker Flank Steak

For serving, flank steak pairs beautifully with:

• Mashed potatoes: The creamy texture complements the tender meat.
• Steamed or roasted vegetables: Light veggies balance out the rich flavors of the steak.
