🛒 Ingredients & Substitutions

  • flank steak – substitute with sirloin, skirt steak, or stewing beef sliced thin
  • onion – substitute with shallots
  • garlic – substitute with ½ teaspoon garlic powder if needed
  • beef stock – substitute with beef broth or vegetable broth
  • stir-fry style sauce – substitute with soy sauce mixed with 1 teaspoon oyster sauce
  • brown sugar – substitute with honey
  • cornflour (cornstarch) – substitute with arrowroot powder
  • broccoli florets – substitute with broccolini or snap peas

✨ Variations

  • Add sliced bell peppers or mushrooms for extra vegetables.
  • Stir in a splash of sesame oil at the end for deeper flavor.
  • Make it spicy by adding red pepper flakes or sliced chili peppers.
  • Serve it over cauliflower rice for a lower-carb option.
  • If you prefer something closer to a beef and broccoli stir fry, cook the sauce on the stovetop and quickly sauté the beef before combining.

🔥 Tips

  • Slice the beef thinly against the grain for the most tender texture.
  • Do not add the broccoli too early, or it will become soft and dull in color.
  • Taste the sauce before serving and adjust salt if needed.
  • If the sauce is too thin, let it cook uncovered for 15 to 20 minutes after adding the slurry.
  • For the best results with crockpot beef and broccoli, avoid lifting the lid during cooking.

❓ FAQs

Can I make beef and broccoli in the crock pot on high instead of low?

Yes. Cook on high for 3 to 4 hours, but low heat produces more tender beef.

Can I use frozen broccoli?

Yes, but add it during the last 20 to 30 minutes and expect a slightly softer texture.

Can I double this recipe?

Yes. Make sure your slow cooker is large enough and allow a little extra cooking time if needed.

Can I make slow cooker beef and broccoli ahead of time?

Absolutely. It tastes even better the next day once the flavors have had time to blend.

    Would you have to change your cooking time if you used chicken?

    This looks so yummy! I love meals in the crockpot–set it and leave it!
    I am visiting from Skip to my Lou, and I have been looking through all your projects. You have some great, great stuff here! I would love it if you'd come over and link up some of your OLDER posts (that's right, Older). I host and oldie's link party, where we strive to give a little more exposure to those old, awesome posts that we were writing when only our moms and husbands were reading our blogs (or was that just me?!?)
    So, consider stopping by!
