Slow Cooker Broccoli Beef | Creme de la Crumb

This past November we visited my grandparents in California and promised them that they were welcome at our house for dinner the next time they were in town. Well, this past weekend they were in town and they took us up on this offer. 

I’m happy to report, this broccoli beef did not fail me. My grandparents (and Pops!) went on and on and onnnnnn about how much they loved it. Can I get a woot! woot! for impressing the husband, father, grandmum and grandpop in one fell swoop?

So easy, incredibly tasty, healthy, and company-worthy… just do yourself a big fat favor and skip the takeout in favor of home cooked next time you’re craving this Asian classic.

Here’s What You Need

  • Flank steak
  • Beef broth
  • Low sodium soy sauce
  • Brown sugar
  • Sesame oil
  • Minced garlic
  • Red chili flakes (optional)
  • Broccoli florets
  • Cornstarch
  • Cold water 

Here’s How You Make it

Wondering how to make broccoli beef in your crockpot? It’s easy! I’ll walk you through it. Not only is this delicious, it’s super simple to throw together in the slow cooker, go on about your day, and come back a few hours later to dig in. 

  1. After I’ve chopped, cut, and measured all the ingredients, I bring them all over to the slow cooker to put in and forget about it for a good 4-5 hours. 
  2. First, grease the inside of the slow cooker, then add the steak, broth, soy sauce, brown sugar, oil, garlic and chili flakes if you are using it. Add the lid and cook on high for 2-3 hours or low for 4-5 hours. 
  3. Make a slurry from cornstarch and water right before you’re ready to serve this beef recipe. Then, add the slurry to the slow cooker and stir it into the sauce. Put the lid back on and let the sauce cook up and thicken for another 20-25 minutes. 
  4. Now for the broccoli. While you’re waiting for the sauce to thicken, microwave your florets (or steam on the stovetop) and add the broccoli to the beef right before serving, mixing in well to coat the broccoli in the delicious sauce.
  5. Time to serve this delicious dish, sit back and watch the smiles form on everyone’s faces as they enjoy this better-than-takeout Slow Cooker Broccoli Beef.

Expert Tips and Tricks

While this broccoli beef dish is great the way it is, there are plenty of ways to tweak it to your tastes: 

  • Add 1-2 teaspoons of red pepper flakes to the beef and sauce before setting the cooking time.
  • For even more heat, top with Sriracha after plating the dish. 
  • Use a combination of broccoli and cauliflower for your vegetables. Or, add in more Asian veggies like snow peas, water chestnuts, or thick-cut carrots. 
  • For a super fast shortcut to cooking the vegetables, use frozen broccoli that cooks right in the bag. Follow the directions on the bag for best results. 
  • Purchase already-cut flank steak at your grocery store or ask the butcher. You might find it labeled “fajita steak” or something to that effect. You can just add that right into the slow cooker, no cutting required! 
  • If you are cutting your own flank steak, be sure to cut across the grain. This ensures the muscle fibers are cut as short as possible, thus making the meat as tender (i.e. not chewy) as possible. 
  • If you have trouble cutting your steak, you can freeze it first for up to an hour to make it easier to slice into. 
  • I like to garnish this with sliced green onions or cilantro. This gives the dish a little more bite at the end.  

What Cut of Beef do Chinese Restaurants Use?

Chinese restaurants usually use a topside of beef. Something like flank steak, that’s low in fat and can be sliced easily. This ensures the beef cooks up nice and tender and just makes for the best stir-fries and other Asian beef dishes like this one.

You can also use skirt steak, hanger steak, or even brisket if that’s all you have/can find. Happy eating!

I found your recipe a number of years ago and think it’s outstanding. I make it at least once a month and am recently on a keto kick and this is very easy to adjust to fit the low carb lifestyle. Thanks for a great recipe!

3 stars
Added some ingredients that brought it up a notch, but when i made it as is it was just okay. Not bad, but lack-luster.
