Ingredients List

Crockpot Beef and Broccoli starts with a handful of simple, flavor-packed ingredients. You likely have most of these in your pantry right now.

For the Beef & Marinade:

• 2 pounds flank steak or sirloin steak, sliced thinly against the grain
• 1/2 cup low-sodium soy sauce (or tamari for gluten-free)
• 1/3 cup packed brown sugar (light or dark)
• 1/4 cup beef broth or water
• 2 tablespoons hoisin sauce
• 4 cloves garlic, minced
• 1 tablespoon fresh ginger, grated
• 1 tablespoon sesame oil
• 1/2 teaspoon black pepper

For the Sauce Thickener & Veggies:

• 3 tablespoons cornstarch
• 3 tablespoons cold water
• 4-5 cups fresh broccoli florets (about 1 large head)
• Sesame seeds and sliced green onions, for garnish

Smart Swaps & Notes:

• Beef: Flank and sirloin are my top picks, but chuck roast, cut into thin strips, also works wonderfully in crockpot recipes slow cooker style, becoming fall-apart tender.
• Gluten-Free: Use tamari instead of soy sauce and ensure your hoisin sauce is certified gluten-free.
• Lower Sugar: You can reduce the brown sugar to 1/4 cup; the sauce will be less glossy but still deeply savory.
• Broccoli: Frozen broccoli florets can be used in a pinch. Add them frozen during the last 30 minutes of cooking.

Timing

One of the greatest joys of this Crockpot Beef and Broccoli is how the hands-off cooking time gives you your afternoon back.

• Prep Time: 15 minutes
• Cook Time: 3-4 hours on LOW or 1.5-2 hours on HIGH
• Total Time: About 3 hours 15 minutes (on LOW setting)

Compared to traditional stir-fry methods, which require constant attention, this slow cooker approach is about 80% less active time. You get all the flavor with a fraction of the work, making it a champion among easy crockpot recipes.

Step-by-Step Instructions

1. Prep the Beef and Marinade

Thinly slice your beef against the grain. This is the single most important step for tender beef! It shortens the muscle fibers, so even a lean cut like flank steak becomes easy to chew. In a medium bowl, whisk together the soy sauce, brown sugar, broth, hoisin, garlic, ginger, sesame oil, and pepper. Pour this over the sliced beef in your slow cooker insert and toss to coat every piece. You can let it marinate right there for 15 minutes while you prep the broccoli, or just move on to cooking.

2. Slow Cook to Tender Perfection

Place the lid on your slow cooker. For the most tender, shreddable beef, cook on LOW for 3-4 hours. If you’re short on time, cook on HIGH for 1.5-2 hours. The beef should be fully cooked and tender when pierced with a fork. Avoid overcooking on HIGH, as lean cuts can become dry.

3. Thicken the Sauce

Once the beef is tender, it’s time to create that luxurious, glossy sauce that makes this Crockpot Beef and Broccoli so irresistible. In a small bowl, make a slurry by whisking the cornstarch and cold water together until completely smooth. Stir this slurry into the hot liquid in the slow cooker. Replace the lid and cook on HIGH for an additional 20-30 minutes. You’ll see the sauce transform from thin and watery to beautifully thick and clingy.

4. Add the Broccoli

In the last 20-30 minutes of cooking (after you’ve added the thickener), stir in the fresh broccoli florets. They will steam perfectly in the heat of the slow cooker, becoming bright green and tender-crisp. This preserves their texture and nutrients—no mushy broccoli here!

5. Serve and Garnish

Give everything a final stir to coat the beef and broccoli in that rich sauce. Serve immediately over a bed of steamed white rice, brown rice, or cauliflower rice. Garnish generously with sliced green onions and a sprinkle of sesame seeds for that finishing touch.

• Gluten-Free: Use tamari and a gluten-free hoisin sauce. Double-check that your beef broth is also gluten-free.
• Lower-Carb/Keto: Replace the brown sugar with a brown sugar substitute like Swerve or Lakanto. Use a keto-friendly hoisin alternative or make your own, and thicken the sauce with xanthan gum (about 1/2 teaspoon) instead of cornstarch. Serve over cauliflower rice.
• Paleo/Whole30: Use coconut aminos instead of soy sauce, omit the brown sugar, and use date paste or a compliant sweetener. Ensure your broth and any added sauces are compliant.
• Less Sugar: Simply reduce the brown sugar by half. The sauce will be less sweet and more focused on the savory, umami notes.

• Add More Veggies: Stir in sliced bell peppers, matchstick carrots, or snap peas with the broccoli for extra color and nutrition.
• Boost the Flavor: Offer chili crisp or sriracha on the side for those who like a little heat. A drizzle of extra sesame oil right before serving adds wonderful aroma.

Common Mistakes to Avoid

A few simple tips will guarantee your Crockpot Beef and Broccoli turns out perfect every time.

• Slicing With the Grain: Always slice your beef against the grain. Slicing with it will result in chewy, tough strips, no matter how long you cook it.
• Adding Broccoli Too Early: If you add the broccoli at the beginning, it will turn into a sad, olive-green mush. The last 20-30 minutes is perfect for tender-crisp results.
• Not Making a Smooth Slurry: Dumping dry cornstarch directly into the hot liquid will cause lumps. Always mix it with cold water first until it’s completely smooth.
• Overcooking on High: Lean cuts like flank steak don’t need all day. 1.5-2 hours on HIGH is sufficient. Overcooking can make them dry.
• Skipping the Garnish: The green onions and sesame seeds aren’t just pretty—they add a crucial fresh flavor and nutty texture that elevates the whole dish.

Storing Tips for the Recipe

This dish makes fantastic leftovers, often tasting even better the next day as the flavors continue to meld.

• Refrigerator: Store cooled leftovers in an airtight container for up to 4 days.
• Freezer: Freeze in airtight containers or heavy-duty freezer bags for up to 3 months. The texture of the broccoli may soften slightly upon thawing, but the flavor will still be excellent. Thaw overnight in the refrigerator before reheating.
• Reheating: Reheat gently in a saucepan over medium-low heat, adding a splash of water or broth if the sauce has thickened too much. You can also reheat individual portions in the microwave, covered, stirring every 60 seconds until hot.
