🔥 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.

    I never thought of doing Chinese in a crock pot. So I'll give it a try, I have a wok but cleaning it isn't my favorite thing to do, and no good Chinese restaurants around here. Sounds good!

    That sounds so good! I must admit…I have never heard of Sriracha sauce (Rooster sauce). Can you find it next to other sauces like Soy sauce? Glad I came across your blog from the hop.

    Have a great evening! Julie from Stlavonlady – a cat, girl, man and me!
