This slow cooker beef and broccoli rivals your local takeout spot with impossibly tender beef, a glossy savory sauce, and bright green broccoli. No searing required—just five minutes of prep in the morning for a set-it-and-forget-it dinner.

Ingredients

Scale
  • 2 pounds flank steak or sirloin, thinly sliced against the grain (frozen works perfectly)
  • 1/3 cup cornstarch
  • 1/2 cup low-sodium soy sauce
  • 1/3 cup packed brown sugar (light or dark)
  • 1/2 cup low-sodium beef broth
  • 3 cloves garlic, minced (or 1 teaspoon garlic powder)
  • 1 teaspoon fresh ginger, grated (or 1/2 teaspoon ground ginger)
  • 2 tablespoons honey
  • 1 tablespoon rice vinegar
  • 1/4 teaspoon red pepper flakes (optional)
  • 3 cups fresh broccoli florets (about one large crown)
  • 1 tablespoon water (for steaming broccoli)
  • 1 tablespoon toasted sesame oil
  • 1 tablespoon cornstarch mixed with 2 tablespoons cold water (slurry)
  • Sesame seeds and sliced green onions for garnish

Instructions

  1. Slice the Beef (5 minutes): If using thawed beef, place it in the freezer for 20 minutes first—it slices much easier when partially frozen. Cut the flank steak against the grain into thin strips, about 1/4-inch thick. If using frozen beef, skip this step entirely and proceed to step 2.
  2. Coat the Beef (5 minutes): In a medium bowl, toss the beef slices with 1/3 cup cornstarch until evenly coated. This step is crucial—the cornstarch helps thicken the sauce and gives the beef that silky texture. Don’t skip it, even if you’re using frozen beef. For frozen beef, sprinkle the cornstarch over the top and toss as best you can; it won’t be perfect, and that’s fine.
  3. Make the Sauce (5 minutes): In a separate bowl, whisk together the soy sauce, brown sugar, beef broth, minced garlic, grated ginger, honey, rice vinegar, and red pepper flakes (if using). Taste it—it should be salty, sweet, and slightly tangy. Adjust to your preference now, because you won’t be able to adjust later without thinning the sauce.
  4. Combine in the Slow Cooker (2 minutes): Place the cornstarch-coated beef into the slow cooker. Pour the sauce over the top and stir to coat every piece. Yes, even if the beef is frozen—just pour and stir. The sauce will look thin, but trust the process.
  5. Cook Low and Slow (4-6 hours on LOW or 2-3 hours on HIGH): Cover and cook on LOW for 4-6 hours or on HIGH for 2-3 hours. I strongly recommend LOW for the most tender beef. At the 3-hour mark on LOW, give it a stir. You’ll notice the sauce has darkened and thickened slightly. The beef should be fork-tender but not falling apart into strings.
  6. Prepare the Broccoli (5 minutes, during the last 10 minutes of cooking): When the beef has about 10 minutes left, steam the broccoli. Place the florets in a microwave-safe bowl with 1 tablespoon of water, cover with a plate, and microwave on HIGH for 2-3 minutes until bright green and crisp-tender. Alternatively, steam in a skillet with a lid over medium heat for 3-4 minutes. You want the broccoli to still have a slight crunch—it will continue cooking slightly when added to the hot beef.
  7. Thicken the Sauce (2 minutes): In a small bowl, mix 1 tablespoon cornstarch with 2 tablespoons cold water until smooth. Remove the lid from the slow cooker and stir in the slurry. Let it cook uncovered on HIGH for 5-10 minutes, stirring occasionally, until the sauce reaches a glossy, gravy-like consistency. If it’s still too thin, mix another teaspoon of cornstarch with a tablespoon of water and stir it in.
  8. Add the Broccoli and Sesame Oil (1 minute): Gently fold the steamed broccoli into the beef and sauce. Drizzle with the toasted sesame oil and stir once more. The sesame oil is the magic touch—it adds that unmistakable takeout aroma. Taste and adjust salt if needed (I usually don’t need any).
  9. Serve Immediately: Spoon the beef and broccoli over steamed rice (jasmine or basmati work beautifully) and garnish with sesame seeds and sliced green onions. The sauce will continue to thicken as it sits, so serve right away for the best texture.

Notes

For gluten-free, use tamari or coconut aminos instead of soy sauce and ensure beef broth is certified gluten-free. For a lower-sodium version, use low-sodium soy sauce and reduce added salt. For a lower-sugar version, reduce brown sugar and honey to 1/4 cup total. The sauce gets even richer after a day in the fridge.
