Ingredients

• 1 ½ pounds boneless beef chuck roast, cut into ¼-inch strips
• 1 cup low-sodium beef broth
• ½ cup low-sodium soy sauce
• ⅓ cup dark brown sugar
• 1 tablespoon sesame oil
• 3 teaspoons minced garlic, about 3 cloves
• 2 tablespoons cornstarch
• 1 (12-ounce) bag frozen broccoli florets, about 3 cups

Step-by-Step Instructions

Step 1: Prepare the Beef

Cut the boneless beef chuck roast into thin, approximately ¼-inch strips. Trim away any large pieces of excess fat, keeping some marbling for flavor and tenderness.

Place the beef strips in the slow cooker in an even layer.

Step 2: Make the Sauce

In a medium bowl, whisk together the beef broth, low-sodium soy sauce, dark brown sugar, sesame oil, and minced garlic until the sugar begins to dissolve.

Pour the sauce mixture over the beef, making sure the strips are coated.

Step 3: Slow Cook the Beef

Cover and cook on LOW for 4–5 hours or on HIGH for 2–3 hours, until the beef is tender. Cooking time may vary depending on your slow cooker and the thickness of the beef strips.

For the best texture, check the beef toward the earlier end of the cooking window and continue cooking if needed.

Step 4: Thicken the Sauce

About 20–30 minutes before serving, whisk the cornstarch with 2 tablespoons of cold water in a small bowl until smooth.

Stir the slurry into the slow cooker liquid. Cover and cook on HIGH for approximately 15–20 minutes, stirring once if convenient, until the sauce thickens.

Step 5: Add the Broccoli

Add the frozen broccoli florets directly to the slow cooker. Stir gently to coat them in the sauce.

Cover and cook for another 15–25 minutes, or until the broccoli is heated through and tender but still holds its shape. Avoid cooking it too long, as broccoli can become soft and lose its bright green color.

Step 6: Serve

Stir the beef and broccoli gently to distribute the thickened sauce. Taste and adjust the seasoning if needed.

Serve hot over steamed white rice, brown rice, or noodles. Spoon extra sauce over each serving.

Recipe Tips for Success

• Slice the beef evenly: Thin, uniform strips cook more consistently and are easier to eat.
• Use low-sodium soy sauce: This helps keep the sauce from becoming too salty as it cooks.
• Mix the cornstarch with cold water: Adding dry cornstarch directly to the slow cooker can create lumps.
• Add broccoli near the end: Frozen broccoli needs much less cooking time than the beef.
• Adjust the sauce thickness: If the sauce is too thin, cook it a little longer with the lid slightly ajar, or add a small amount of additional cornstarch slurry.
• Check the beef for tenderness: The beef should be easy to bite through. If it is still firm, continue cooking and check again.
• Use a food thermometer when appropriate: For beef strips, check that the meat reaches a safe temperature; tenderness can require additional cooking depending on the cut and preparation.

Ingredient Substitutions

• Beef chuck roast: Boneless beef stew meat or flank steak cut into strips can work, although cooking time and texture may differ.
• Low-sodium beef broth: Regular beef broth works, but the finished sauce may be saltier.
• Low-sodium soy sauce: Tamari can be used as a gluten-free alternative if the other ingredients are also gluten-free. Coconut aminos can be used for a different, generally sweeter flavor.
• Dark brown sugar: Light brown sugar can be substituted. The sauce may have a slightly milder molasses flavor.
• Sesame oil: Use a small amount of neutral oil if necessary, though the dish will lose some of its characteristic sesame aroma.
• Frozen broccoli: Fresh broccoli florets can be used. Add them near the end and cook until tender.
• Cornstarch: Arrowroot starch may work as an alternative thickener; follow the package guidance for substitution.

Recipe Variations

Spicy Beef and Broccoli

Add red pepper flakes or a little chili garlic sauce to the sauce mixture for a gentle kick of heat.

Honey Beef and Broccoli

Replace some or all of the brown sugar with honey. The flavor will be slightly different, with a more pronounced honey sweetness.

Extra-Garlicky Beef and Broccoli

Add another clove or two of minced garlic if you enjoy a stronger garlic flavor.

Beef and Vegetable Stir-In

Add sliced bell peppers or carrots near the end of cooking. They may need a little more time than broccoli, depending on how thinly they are cut.

Gluten-Free Beef and Broccoli

Use certified gluten-free tamari instead of soy sauce and confirm that the broth and cornstarch are gluten-free.

Storage and Reheating

Refrigeration: Allow leftovers to cool slightly, then transfer them to an airtight container and refrigerate within 2 hours. Store for up to 3–4 days.

Freezing: Freeze cooled beef and sauce in a freezer-safe container for up to 2–3 months for best quality. Broccoli may soften after freezing and reheating, so its texture may change.

Reheating on the stovetop: Warm the beef and broccoli in a saucepan over medium-low heat, stirring occasionally. Add a splash of water or broth if the sauce has thickened too much.

Reheating in the microwave: Place a portion in a microwave-safe dish, cover loosely, and heat in short intervals, stirring between each interval until evenly hot.

For food safety, reheat leftovers to 165°F (74°C).

Serving Suggestions

Serve this slow cooker beef and broccoli with:

• Steamed jasmine or basmati rice
• Brown rice for a heartier side
• Lo mein or rice noodles
• Cauliflower rice for a lower-carbohydrate option
• Steamed dumplings or spring rolls
• A simple cucumber salad for a fresh contrast

For a classic takeout-style dinner, serve the beef and broccoli over fluffy white rice and drizzle extra sauce over the top.

Frequently Asked Questions

Can I put raw beef directly into the slow cooker?

Yes. The beef can go directly into the slow cooker without browning first. Browning it in a hot skillet beforehand is optional and can add extra flavor, but it is not necessary for this simple recipe.

Can I use fresh broccoli instead of frozen?

Yes. Fresh broccoli florets work well. Add them during the final 15–25 minutes of cooking and check them regularly so they do not become overcooked.

Why is my beef and broccoli sauce too thin?

The sauce may need more time to thicken after adding the cornstarch slurry. Make sure the cornstarch is mixed with cold water first, then allow the sauce to cook until glossy. If needed, add a little more slurry.

Can I cook this recipe on HIGH?

Yes. Cooking on HIGH for approximately 2–3 hours may work, depending on your slow cooker and the beef strips. Check for tenderness rather than relying only on the clock.

Can I prepare the ingredients ahead of time?

Yes. Slice the beef and mix the sauce ingredients ahead of time. Refrigerate them separately in covered containers, then combine them in the slow cooker when ready to cook. Keep raw beef refrigerated until use.

Can I use a different cut of beef?

Yes. Beef stew meat or flank steak can be used, but the texture and cooking time may change. Chuck roast is a good choice because its marbling helps it become tender during slow cooking.

Is this recipe spicy?

No. The basic recipe is savory and slightly sweet, without significant heat. Add chili flakes or chili garlic sauce if you prefer a spicy version.

What should I serve with slow cooker beef and broccoli?

Rice is the classic choice because it absorbs the sauce well. Noodles, brown rice, or cauliflower rice are also good options.
