I’ve been making this Crockpot beef and broccoli for years when dinner needs to be effortless but still feel special. Thinly sliced beef braises low and slow in a savory-sweet sauce, then tender-crisp broccoli gets added near the end so the whole dish is glossy, saucy, and perfect spooned over rice. It’s exactly the kind of weeknight dinner that disappears fast and invites seconds.

Why you’ll love this dish

This slow-cooker version of beef and broccoli gives you restaurant-style comfort with almost no babysitting. The sauce develops deep flavor as the beef simmers all afternoon, so you get a juicy, tender result without standing over a hot pan. It’s budget-friendly (use skirt or flank steak), kid-friendly, and great for meal prep.

“Simple pantry staples, hands-off cooking, and a sauce your family will fight over — exactly the midweek win I needed.”

Step-by-step overview

This recipe is straightforward: combine the sauce, add sliced beef, slow-cook until tender, stir in broccoli near the end, and thicken with a cornstarch slurry. Expect 4–5 hours on low for most slow cookers, then 25–30 minutes for the broccoli to heat through and the sauce to thicken. No searing required unless you want extra caramelized flavor.

What you’ll need

1 lb beef, sliced thinly (flank, skirt, or sirloin; slice against the grain)
2 cups broccoli florets (fresh works best; frozen can be used but add sooner)
1 cup beef broth (low-sodium if preferred)
1/4 cup soy sauce (or tamari for gluten-free)
2 tablespoons brown sugar (or honey/maple syrup)
2 cloves garlic, minced
1 teaspoon ginger, minced (or 1/2 tsp ground ginger)
2 tablespoons cornstarch
2 tablespoons water
Salt and pepper to taste
Cooked rice, for serving

Substitutions & notes: swap tamari for soy to make it gluten-free, or use arrowroot instead of cornstarch (mix arrowroot with cold water right before adding). If you prefer a leaner option, use thinly sliced sirloin; for more fat and flavor, flank or skirt steak is ideal. For a one-pan dinner twist, serve over egg noodles or toss with cooked orzo — similar vibes to this chicken sausage and broccoli orzo if you want a pasta-based inspiration.

Step-by-step instructions

Whisk together the beef broth, soy sauce, brown sugar, minced garlic, and minced ginger in the slow cooker.
Add the thinly sliced beef. Stir to coat the slices in the sauce so they’re evenly seasoned.
Cover and cook on LOW for 4–5 hours, or until the beef is fork-tender. Check at 4 hours — slow cookers vary.
About 30 minutes before serving, add the broccoli florets. Stir gently to combine.
In a small bowl, mix the cornstarch and water to make a smooth slurry. Pour it into the slow cooker and stir. Let the sauce simmer on LOW until it thickens, about 20–30 minutes.
Taste and adjust with salt and pepper. Spoon the beef and broccoli over hot cooked rice and serve immediately.

Best ways to enjoy it

Serve over steamed jasmine or brown rice. For a lighter plate, try cauliflower rice.
Garnish with toasted sesame seeds and chopped scallions for texture and freshness.
Add a squeeze of lime or a drizzle of chili oil for brightness and heat.
For a family-style dinner, place the slow cooker on the table with bowls of rice and toppings so everyone customizes their bowl.
If you’d rather swap rice for something heartier, tossing the finished beef and sauce with cooked bowtie pasta is delicious — see this creamy beef pasta idea at bowtie pasta with beef, cream, garlic & parmesan for inspiration.

Storage and reheating tips

Refrigerate leftovers in an airtight container within 2 hours of cooking. Keep up to 3–4 days.
Reheat gently on the stovetop over low heat, stirring and adding a splash of water or broth if the sauce is too thick. Microwaving in 30-second bursts also works.
To freeze: cool completely, place in freezer-safe containers, and freeze for up to 3 months. Thaw in the fridge overnight before reheating.
Food safety note: always reheat until steaming hot (165°F / 74°C) and don’t refreeze previously frozen leftovers unless fully cooked and cooled.

Pro chef tips

Slice the beef very thin against the grain — it makes a huge difference in tenderness. Partially freezing the meat for 20–30 minutes makes it easier to slice thinly.
If you like deeper flavor, quickly sear the beef in a hot skillet before adding to the slow cooker; it’s optional but adds caramelized notes.
Don’t add broccoli too early. Adding it in the last 25–30 minutes keeps it bright green and slightly crisp.
Cornstarch must be mixed into cold water first (a slurry) to avoid clumping. Stir it in and allow time for the sauce to thicken; prolonged cooking can thin the sauce, so adjust at the end.
Use low-sodium soy sauce if you plan to reduce the sauce on the stove later — taste and adjust salt at the end.

Creative twists

Spicy sesame: add 1–2 tsp chili garlic sauce and finish with sesame oil and seeds.
Orange beef: stir in 2 tbsp orange marmalade and 1 tsp rice vinegar before serving for an orange beef twist.
Vegetarian swap: replace beef with extra-firm tofu (pressed and cubed) and mushrooms; shorten cooking time accordingly.
Low-carb: serve over cauliflower rice and use tamari for a gluten-free option.
Add crunch: toss in roasted cashews or water chestnuts just before serving.

Common questions

Q: Can I use frozen beef?
A: It’s best to thaw and slice beef before slow cooking. Thin slices from partially frozen meat are easiest to cut evenly.

Q: What cut of beef is best?
A: Flank or skirt steak gives great flavor and becomes tender when cooked low and slow. Sirloin works too and is a bit leaner.

Q: How long will leftovers keep?
A: Stored properly in the fridge, leftovers are good for 3–4 days. Freeze up to 3 months.

Q: Can I thicken the sauce without cornstarch?
A: Yes — use arrowroot (same method), or reduce the sauce on the stovetop, but watch closely to avoid over-reducing or burning.

Q: My broccoli turned mushy — what went wrong?
A: Broccoli needs less time than beef. Adding it with ~30 minutes left helps keep it bright and crisp. Frozen broccoli should be monitored and added even later if already blanched.
