Instructions to Make Beef and Broccoli
Step One: Add Steak to Crockpot

Recipe Variations and Add-ins
This easy crockpot beef and broccoli is so easy to make at home. Even if you love traditional beef and broccoli, we’ve got a few new ideas and ways you can change the recipe and it will still be a wonderful recipe.
- Broccoli – Fresh broccoli is preferred because you don’t want it to be mushy. But if you want to use frozen broccoli you can, just make sure you add and cook it just long enough to be warmed through.
- Cut of beef – For best results use beef that has a little marbling in it. This is what renders tender beef. A sliced boneless beef chuck roast is a great choice. You can even use beef stew meat if it’s good quality.
- Other veggies – Feel free to add other fresh veggies such as bell peppers, snap peas, carrots, or mushrooms.
- Red pepper flakes – If you like a little kick of heat next time, you can add a pinch of red pepper flakes to the sauce with the other ingredients.
- Fresh ginger – Freshly grated ginger adds a bright and zesty addition to the sauce. Just remember that a little goes a long way.
How to Store Leftovers?
- Refrigerator – Place the leftover beef and broccoli in an airtight container in the fridge for up to 3-4 days.
- Freezer – Transfer leftovers to a freezer-safe container. Label the container with the date. Beef and Broccoli can be frozen for up to 2 to 3 months. Thaw in the fridge overnight before reheating.
What’s the Difference Between Beef and Broccoli and Mongolian Beef?
Beef and Broccoli and Mongolian beef both call for thinly sliced beef. Beef and broccoli include broccoli florets that are cooked together in a savory sauce. Mongolian Beef is stir-fried with green onions in a sauce that is sweeter, often including hoisin sauce for a slightly caramelized and sticky texture.
What Sauce is Beef and Broccoli Made Of?
It’s a combination of various flavorful ingredients that give the dish its distinctive taste. The sauce typically consists of soy sauce, garlic, ginger, brown sugar, and often a thickening agent like cornstarch. This mixture infuses the beef and broccoli with a savory, sweet, and slightly tangy flavor profile.
How Can I Thicken Beef and Broccoli Sauce?
Before adding the broccoli, if the sauce seems thinner than you’d prefer, you can make an additional cornstarch slurry in a small bowl and slowly add it to the sauce. Whisk it until it has incorporated with the other ingredients.
Can You Use Frozen Broccoli in this Recipe?
I used fresh broccoli and recommend that method over frozen broccoli. The frozen broccoli will add water to the recipe and will change the consistency. If you must use frozen broccoli, I recommend following the cooking instructions on the package and add in the broccoli at the very end, right before serving.
How Long Does Broccoli Take to Soften in the Crockpot?
Fresh broccoli typically takes about 1 to 2 hours on the low setting or 30 minutes to 1 hour on the high setting in a slow cooker to soften. It’s important not to overcook it, so check for tenderness as it cooks, aiming to maintain its bright green color and a slight crunch. Overcooking can lead to mushy and discolored broccoli. Adjust the cooking time as needed based on the size of the florets and your specific slow cooker model.
Can You Cook Diced Beef From Frozen in Slow Cooker?
Yes, you can cook diced beef from frozen in a slow cooker. Slow cookers are designed to safely cook frozen meats over a longer period of time, as they gradually thaw and then cook. However, it’s essential to ensure that the internal temperature of the beef reaches a safe level of at least 165°F (74°C). Cooking times will be longer when starting with frozen beef, so plan for an extended cooking period, and consider adding extra liquid or adjusting the recipe accordingly to prevent the dish from drying out during the longer cook time.
What to Serve with the Best Beef and Broccoli?
Typically the best beef and broccoli is served over jasmine rice. You can put the beef and sauce over white rice. You can serve it as is or check out our collection of What to Serve with Beef and Broccoli recipes.
