Ingredients You’ll Need

1 ½ lb flank steak or stewing beef, sliced thin: Flank steak is ideal for tenderness. Stewing beef works too. Ensure it’s cut into thin strips to soak up the flavor beautifully.
1 medium onion, diced: Adds depth and sweetness. You can use yellow or white onions, depending on your preference.
2 cloves garlic, minced: Garlic brings an aromatic punch to the dish, enhancing the overall flavor profile.
½ cup beef stock: This creates the rich base for our sauce. Low-sodium options allow you to control salt levels.
¼ cup soy-free stir-fry style sauce or Worcestershire-based substitute: For a soy-free dish, look for stir-fry sauces made from tamari or coconut aminos.
1 tablespoon brown sugar: A touch of sweetness balances out the savory flavors. You can substitute with honey or agave if preferred.
1 tablespoon cornflour (cornstarch): Used to thicken the sauce towards the end of cooking, giving it that perfect coating consistency.
10 oz broccoli florets: Fresh or frozen, broccoli adds color and nutrition. Add it towards the end to keep it tender-crisp.
Cooked rice or noodles: These make the perfect base for soaking up that delicious sauce.
Sesame seeds: For garnish, they add an appealing crunch and flavor contrast at the finish.

How to Make Tender Beef and Broccoli Slow Cooker

Combine Ingredients: In your slow cooker, add 1 ½ lb thinly sliced flank steak, 1 medium diced onion, 2 minced cloves of garlic, ½ cup beef stock, ¼ cup soy-free stir-fry style sauce (or your Worcestershire substitute), and 1 tablespoon brown sugar. Stir gently to mix everything well.
Set It: Cover the slow cooker and let it work its magic. Cook on low for 5–6 hours until the beef is tender and flavors meld together beautifully.
Make the Slurry: In a small bowl, mix 1 tablespoon cornflour with 2 tablespoons cold water. This will be your thickening agent for the sauce.
Thicken the Sauce: When your beef is perfectly tender, stir the cornflour slurry into the slow cooker. This will thicken your delicious sauce, making it rich and coating the beef splendidly.
Add Broccoli: Toss in 10 oz broccoli florets during the last 30 minutes of cooking. Cover it again and keep cooking until the broccoli is bright and tender, yet still has some crunch.
Taste and Adjust: Give your dish a taste. Depending on your flavor preference, adjust seasoning if necessary.
Serve: Warm up some cooked rice or noodles to serve this beauty atop. Garnish with sesame seeds for that extra flair.

Storing & Reheating

Store any leftovers in a covered container in the refrigerator for 3-4 days. If you need to keep it longer, freeze portions in airtight containers for up to 3 months. When reheating, place in the microwave or on the stovetop until warmed through—about 2-3 minutes should do. Do note that freezing may change the broccoli’s texture, but a quick stir and reheating should refresh the flavors nicely!

Chef’s Helpful Tips

Avoid overcrowding the slow cooker; more than the recommended amounts can lead to longer cooking times.
Slice the meat against the grain for maximum tenderness—it makes all the difference in texture!
Be mindful of the broccoli; adding it too early can result in mushy florets. Aim for the last 30-minute mark.
If you’re looking to amp up the flavor, consider adding a splash of sesame oil or red pepper flakes for a little kick.

Tender Beef and Broccoli Slow Cooker has a way of making everyone feel at home. With ease and deliciousness wrapped into one warm meal, it’s a dish made for sharing, satisfying every craving.
