The cooking process explained
Making this Crockpot Beef and Broccoli is wonderfully straightforward, even with our extra flavor-boosting steps. You’ll start by quickly searing your beef, which is one of our key secrets to a richer flavor. After that, everything goes into the slow cooker with a vibrant, homemade sauce that incorporates our second secret ingredient. The magic then happens slowly over several hours, allowing the beef to become incredibly tender and soak up all those delicious savory notes. Towards the end, we’ll add the broccoli to ensure it cooks to that perfect crisp-tender stage, not mushy. Finally, a quick thickening of the sauce, and you’re ready to serve!
What you’ll need
To get started on this incredibly flavorful Crockpot Beef and Broccoli, gather these items:
- Beef: 2 pounds chuck roast or stew beef, cut into 1-inch pieces
- Broccoli: 4-5 cups fresh broccoli florets
- Beef Broth: 1 cup, low sodium
- Soy Sauce: 1/2 cup, low sodium
- Brown Sugar: 1/4 cup, packed
- Toasted Sesame Oil: 1 tablespoon
- Garlic: 4 cloves, minced
- Fresh Ginger: 1 tablespoon, grated
- Cornstarch: 2 tablespoons
- Water: 2 tablespoons (for cornstarch slurry)
- Olive Oil: 1 tablespoon (for searing)
- Secret Ingredient #1: 1 tablespoon tomato paste (adds incredible umami and depth!)
- Secret Ingredient #2: 1 teaspoon fish sauce (don’t worry, it doesn’t make it fishy, just adds complexity!)
- Optional for garnish: Sesame seeds, chopped green onions
Directions to follow
Let’s get cooking! Follow these easy steps for a delicious Crockpot Beef and Broccoli:
- Sear the Beef: Pat the beef pieces dry with paper towels. Heat olive oil in a large skillet or Dutch oven over medium-high heat. Once hot, sear the beef in batches until browned on all sides. This usually takes 2-3 minutes per side. Browning is crucial for flavor development! Transfer the seared beef to your slow cooker.
- Whisk the Sauce: In a medium bowl, whisk together the beef broth, soy sauce, brown sugar, toasted sesame oil, minced garlic, grated ginger, tomato paste, and fish sauce. Pour this mixture over the beef in the slow cooker.
- Slow Cook: Cover the slow cooker and cook on low for 6-8 hours or on high for 3-4 hours, or until the beef is fork-tender.
- Add Broccoli: About 30-45 minutes before the end of the cooking time, stir in the fresh broccoli florets. Replace the lid and continue cooking until the broccoli is crisp-tender. You don’t want it mushy!
- Thicken the Sauce: In a small bowl, whisk together the cornstarch and 2 tablespoons of cold water until smooth to create a slurry. Remove about 1 cup of the hot sauce from the slow cooker and slowly whisk it into the cornstarch slurry. Pour this mixture back into the slow cooker and stir well.
- Final Touches: Cook for another 15-20 minutes on high, or until the sauce has thickened to your desired consistency.
- Serve: Ladle generously over steamed rice or noodles. Garnish with sesame seeds and green onions, if desired.
Best ways to enjoy it
This Crockpot Beef and Broccoli is a complete meal in itself, but there are definitely ways to enhance the experience. My favorite way to serve it is over a bed of fluffy steamed white or brown rice to soak up all that incredible sauce. If you’re looking for something different, it also pairs beautifully with lo mein noodles or even zucchini noodles for a low-carb option. For an extra pop of freshness and texture, a sprinkle of toasted sesame seeds and some freshly sliced green onions are always a good idea. A side of crispy potstickers or egg rolls would complete a fantastic homemade Asian-inspired meal.
Keeping leftovers fresh
One of the great things about slow cooker meals is how well they store! To keep your Crockpot Beef and Broccoli fresh, allow it to cool completely before transferring it to an airtight container. It will last beautifully in the refrigerator for up to 3-4 days.
For longer storage, this dish also freezes well. Portion it into freezer-safe containers or bags, ensuring you remove as much air as possible to prevent freezer burn. It can be stored in the freezer for up to 2-3 months.
When reheating, thaw completely in the refrigerator if frozen. You can reheat individual portions in the microwave until hot, stirring occasionally. For larger batches, reheat gently in a pot on the stovetop over medium-low heat, adding a splash of beef broth or water if the sauce has become too thick.
Helpful cooking tips
- Don’t skip the sear: I know it’s an extra step for a slow cooker meal, but searing the beef before cooking radically deepens the flavor. It creates a rich, caramelized crust that translates into a more complex final dish.
- Pat your beef dry: Before searing, make sure your beef pieces are thoroughly patted dry. Excess moisture will steam the beef instead of browning it, preventing that delicious crust from forming.
- Broccoli timing is key: Adding the broccoli too early will result in mushy, unappetizing florets. Keep an eye on it during the last 30-45 minutes and remove it from the heat as soon as it reaches that tender-crisp stage.
- Adjust sauce thickness: If your sauce isn’t as thick as you’d like after the cornstarch slurry, you can always make another small slurry (1 tsp cornstarch with 1 tsp cold water) and stir it in, cooking for a few more minutes until thickened.
- Taste and adjust: Before serving, always taste the sauce! You might want to add a tiny splash more soy sauce for saltiness, a pinch more brown sugar for sweetness, or even a dash of rice vinegar for a touch of acidity to brighten everything up.
Creative twists
While this recipe is fantastic as is, there are always ways to put your own spin on it:
- Spice it up: If you like a little heat, add a pinch of red pepper flakes to the sauce along with the other ingredients, or garnish with a drizzle of sriracha before serving.
- Add more veggies: Feel free to toss in other quick-cooking vegetables like sliced bell peppers, snap peas, or shredded carrots during the last hour of cooking.
- Different cuts of beef: While chuck roast is my favorite for its tenderness and flavor, you could also use flank steak or sirloin. Just be aware that these leaner cuts might require a slightly shorter cooking time, especially on high, to avoid drying out.
- Gluten-free option: Easily make this gluten-free by using tamari instead of soy sauce and ensuring your beef broth is gluten-free.
- Citrus brightness: A squeeze of fresh orange juice or a teaspoon of orange zest added to the sauce can give it a lovely, bright undertone, similar to orange beef.
Common questions
Can I use frozen broccoli?
A: Yes, you certainly can! If using frozen broccoli, you’ll want to add it directly to the slow cooker during the last 15-20 minutes of cooking. Frozen broccoli tends to cook faster and can get mushy if added too early.
Why do you sear the beef if it’s going into a slow cooker?
A: Searing the beef is one of our key flavor secrets! It creates a delicious caramelized crust through the Maillard reaction, which adds a significant depth of flavor that you simply can’t achieve by just putting raw beef into the slow cooker. It seals in some juices and creates a wonderful texture.
My sauce isn’t thickening. What should I do?
A: The most common reason for a sauce not thickening is that the cornstarch slurry wasn’t whisked thoroughly or wasn’t cooked long enough after being added back in. Make sure you whisk the cornstarch and cold water until there are no clumps. Once you add it back to the slow cooker, ensure it simmers for at least 15-20 minutes on high. If it’s still too thin, you can make a small additional slurry (1 tablespoon cornstarch with 1 tablespoon cold water) and stir it in, cooking until desired thickness.
Can I make this ahead of time?
A: Absolutely! This Crockpot Beef and Broccoli is excellent for meal prep. You can cook the entire dish, let it cool, and store it in the refrigerator. The flavors often meld even more overnight. Just reheat gently when ready to serve.
