Step‑by‑Step Instructions for Slow Cooker Beef and Broccoli
Step 1: Prep Ingredients
Begin by dicing the white onion into medium pieces for even cooking. Slice the beef roast against the grain into thin strips, which will enhance tenderness. If desired, you can chop the broccoli florets in advance; just be sure to refrigerate them until needed. This prep step ensures a smooth cooking process for your Slow Cooker Beef and Broccoli.
Step 2: Combine Ingredients
In your slow cooker, layer in the sliced beef, diced onion, and pour in 1 cup of beef broth. Next, add 1/2 cup of coconut aminos, 1 tablespoon minced garlic, 2 teaspoons minced ginger, and 3 teaspoons toasted sesame oil. Finish this flavorful mix with 1 teaspoon white wine vinegar, 1/2 teaspoon salt, 1/4 teaspoon pepper, and 1/4 teaspoon Chinese 5 Spice powder. Stir well to ensure everything is nicely blended.
Step 3: Cook
Cover the slow cooker and set it to cook on high for 3 to 4 hours, or on low for 6 hours. During this time, the beef will become tender, and the flavors will meld beautifully. Depending on thickness, adjust the cooking time slightly if your beef slices are particularly thin. An enticing aroma will fill your kitchen, signaling it’s time for the next steps.
Step 4: Thicken Sauce
Once the beef is tender, it’s time to create that luscious sauce. Mix 2.5 tablespoons of arrowroot flour with water until dissolved, then pour it into the slow cooker. Stir thoroughly, allowing the heat to activate the thickening agent. Keep cooking for an additional 10 minutes, confirming that the sauce has thickened to your preferred consistency, making your Slow Cooker Beef and Broccoli even more delectable.
Step 5: Add Broccoli
Now, add the chopped broccoli florets to the slow cooker. Stir well to ensure the broccoli is evenly coated in the delicious sauce. Cover the slow cooker again and let it cook on low for another 10 to 15 minutes. This step allows the broccoli to become tender yet still crisp, complementing the rich flavors of the dish perfectly.
Step 6: Final Touches
Once the broccoli is bright green and tender, give the Slow Cooker Beef and Broccoli a final stir. Taste and adjust seasoning if necessary, perhaps adding a little more salt or a splash of coconut aminos. This is the moment to ensure all the flavors are balanced before serving. Enjoy your healthy, homemade meal that’s ready to impress your family!

Make Ahead Options

When ready to cook, combine your prepped ingredients in the slow cooker as instructed, ensuring to follow through with cooking for 3-4 hours on high or 6 hours on low.

Whole30 Slow Cooker Beef and Broccoli Recipe FAQs
How do I choose the right beef for this recipe?
Absolutely! For the best results, select a beef roast that is well-marbled, as the fat adds flavor and tenderness during cooking. Flank steak and strip steak are also great alternatives, providing similar taste and texture. Just ensure that the beef is fresh, without excess dark spots or a strong smell.
How should I store leftover Slow Cooker Beef and Broccoli?
Very simple! Leftovers can be stored in an airtight container in the refrigerator for up to 4 days. Just allow the dish to cool completely before sealing it to retain its freshness. If you anticipate not finishing it within that timeframe, consider freezing it for longer storage.
Can I freeze Slow Cooker Beef and Broccoli? If so, how?
Absolutely! To freeze, portion the Slow Cooker Beef and Broccoli into freezer-safe containers, ensuring there’s enough space to expand. Label each container with the date and seal tightly. It can be frozen for up to 3 months. When ready to enjoy, transfer it to the fridge to thaw overnight before reheating gently on the stove or microwave.
What should I do if the sauce turns out too thin?
No worries at all! If your sauce isn’t thick enough, mix additional arrowroot flour or cornstarch in a small amount of cold water until dissolved, then stir it into the sauce while it’s still cooking. Allow it to heat for a few more minutes until it thickens up. Aim for a rich, velvety sauce that clings beautifully to the beef and broccoli.
Are there any dietary considerations I should be aware of?
Certainly! This recipe is great for Whole30, Paleo, and Keto diets. However, if you have specific allergies—like those to garlic, onion, or sesame oil—you can substitute the garlic with garlic powder or omit it, and replace sesame oil with a different cooking oil, like olive oil. Always check the labels on coconut aminos to ensure they’re compliant with your dietary needs.
Can I use frozen broccoli in this dish?
Yes, indeed! However, if using frozen broccoli, I recommend adding it during the last 10-15 minutes of cooking. This will keep it from becoming mushy and allow it to maintain that delightful crunch that pairs so well with the tender beef. Enjoy the convenience without sacrificing texture!
