- 3 cloves garlic, minced

Preparation Section
Step 1: Prep the Flank Steak
Start by patting the flank steak dry with paper towels. This helps the seasoning stick better. Rub it with olive oil, then sprinkle generously with salt, pepper, smoked paprika, and cumin. The spices will form a beautiful crust when cooked. Pro tip: Let the steak sit at room temperature for 15 minutes before cooking. This ensures even cooking.
Step 2: Layer the Ingredients
In your slow cooker, pour in the beef broth and balsamic vinegar. Add minced garlic for that aromatic punch. Place the seasoned flank steak on top. If you’re using red wine, pour it in now. The liquid should come halfway up the steak—not too much, not too little. Imagine the flavors mingling as the slow cooker works its magic.
Step 3: Cook Low and Slow
Cover the slow cooker and set it to low for 6-8 hours. Yes, patience is key here. As the flank steak cooks, the connective tissues break down, making it tender. If you’re short on time, switch to high heat for 3-4 hours. But trust me, the low-and-slow method is worth the wait. Your kitchen will smell amazing!
Step 4: Shred and Serve
Once done, remove the flank steak and let it rest for 5 minutes. Use two forks to shred the meat—it should pull apart effortlessly. Return the shredded steak to the juices in the slow cooker for extra flavor. Now it’s ready to be turned into flank steak crock pot tacos, fajitas, or served over rice.

Chef’s Secret
Here’s a little trick: Sear the flank steak in a hot skillet for 2 minutes per side before adding it to the slow cooker. This step locks in the juices and enhances the flavor. It’s an extra step, but it makes a world of difference.
Extra Info
Did you know flank steak is one of the leanest cuts of beef? It’s packed with protein and low in fat, making it a great choice for health-conscious eaters. Just be careful not to overcook it unless you’re using a slow cooker, which tenderizes even the toughest cuts.
Necessary Equipment
- Slow cooker (obviously!)
- Tongs or a spatula for handling the steak
- Measuring cups and spoons
- Paper towels for patting the steak dry
Storage
Store leftovers in an airtight container in the fridge for up to 4 days. The flavors deepen over time, so it tastes even better the next day. For longer storage, freeze portions in resealable bags. Label them with the date so you don’t lose track.
To reheat, simply microwave or warm it on the stovetop with a splash of broth to keep it moist. Avoid reheating in the oven, as it can dry out the meat.
If you froze the flank steak, thaw it overnight in the fridge before reheating. Never microwave frozen meat directly—it ruins the texture.
Tips and Advice
When making slow cook flank steak on grill, finish it on the grill for a smoky char. For those wondering, frozen flank steak crock pot recipes work too—just increase the cooking time by an hour. Always slice against the grain for maximum tenderness. And yes, flank steak does get tender the longer you cook it in a slow cooker. Patience pays off!

Presentation Tips
- Serve shredded flank steak on a bed of cilantro-lime rice for a pop of color.
- Garnish with fresh herbs like parsley or cilantro.
- Add a squeeze of lime for brightness.
- For tacos, use colorful toppings like avocado slices, pico de gallo, and cotija cheese.
Healthier Alternative Recipes

- Keto-Friendly: Serve the steak over cauliflower rice.
- Paleo Option: Skip the red wine and use coconut aminos instead of soy sauce.
- Vegan Twist: Replace the steak with portobello mushrooms.
- Spicy Kick: Add diced jalapeños or a dash of hot sauce to the slow cooker.
Common Mistakes to Avoid
Mistake 1: Skipping the Resting Step
Don’t rush! Letting the flank steak rest after cooking allows the juices to redistribute. Skipping this step results in dry meat. Pro tip: Tent it loosely with foil while it rests.
Mistake 2: Overcooking on High Heat
While high heat speeds things up, it can make the meat tougher. Stick to low heat for best results. Slow and steady wins the race.
Mistake 3: Not Slicing Against the Grain
Slicing with the grain leaves the meat chewy. Always cut across the lines of muscle fibers for tender bites. Practice makes perfect!
