Slow Cooker Teriyaki Beef – Tender, Saucy, and Effortless

Teriyaki beef is one of those meals that feels special without trying too hard. With a slow cooker, it becomes even easier: a few minutes of prep, then you let time do the work. You end up with tender beef in a glossy, savory-sweet sauce that’s great over rice, noodles, or a pile of steamed veggies.

The best part? Your kitchen smells amazing for hours. This is weeknight comfort with takeout-level flavor, made in your own kitchen.

What Makes This Special

This slow cooker version gives you all the flavor with barely any fuss.

The sauce has the right balance of sweet, salty, and umami, thanks to soy sauce, brown sugar, garlic, and ginger. A quick cornstarch slurry thickens it at the end so it clings to every bite. The beef turns silky and pull-apart tender, and it reheats beautifully.

It’s also flexible.

You can use chuck roast, brisket, or even flank steak. Add vegetables at the end or keep it simple—either way, you’ll get a reliable, crowd-pleasing meal that works for meal prep or a relaxed weekend dinner.

Shopping List

• Beef: 2 to 2.5 pounds beef chuck roast (or brisket or flank), trimmed and cut into large chunks or thick slices
• Soy sauce: 1/2 cup (low-sodium recommended)
• Brown sugar: 1/3 cup (light or dark)
• Rice vinegar: 2 tablespoons (or apple cider vinegar)
• Sesame oil: 1 tablespoon
• Garlic: 4 cloves, minced
• Fresh ginger: 1 tablespoon, grated (or 1 teaspoon ground ginger)
• Beef broth or water: 1/2 cup
• Mirin or honey (optional): 1–2 tablespoons for extra gloss and sweetness
• Cornstarch: 2 tablespoons
• Water: 2–3 tablespoons for slurry
• Sesame seeds: For garnish
• Green onions: 3–4, thinly sliced
• Vegetables (optional): Broccoli florets, snow peas, bell peppers, or carrots
• To serve: Cooked rice or noodles, lime wedges (optional)

Instructions

1. Prep the beef: Trim excess fat from the beef and cut into large chunks (about 2–3 inches) or thick slices against the grain. Pat dry with paper towels.
2. Make the sauce: In a bowl, whisk together soy sauce, brown sugar, rice vinegar, sesame oil, minced garlic, grated ginger, and beef broth.

   Add mirin or honey if using.

3. Load the slow cooker: Place the beef in the slow cooker. Pour the sauce over the top, turning the beef so it’s coated.
4. Cook low and slow: Cover and cook on Low for 6–8 hours or on High for 3–4 hours, until the beef is very tender.
5. Steam or blanch veggies (optional): If adding vegetables like broccoli or snow peas, steam or blanch them until crisp-tender near the end of the cook time. You can also stir raw bell peppers or carrots into the slow cooker for the last 45–60 minutes.
6. Shred or slice: Transfer the beef to a cutting board.

   Shred with two forks or slice across the grain. Skim any excess fat from the liquid in the slow cooker.

7. Thicken the sauce: Stir cornstarch with 2–3 tablespoons water to make a slurry. Whisk it into the hot cooking liquid.

   Cover and cook on High for 10–15 minutes until the sauce thickens and turns glossy.

8. Combine and finish: Return the beef to the slow cooker and stir to coat. Fold in cooked vegetables if using. Taste and adjust with a splash of soy for saltiness, vinegar for brightness, or a touch of sugar/honey if you want sweeter.
9. Serve: Spoon the teriyaki beef over rice or noodles.

   Top with sesame seeds and green onions. A squeeze of lime adds a nice pop.

Keeping It Fresh

Cool leftovers quickly and store them in airtight containers. In the fridge, the beef and sauce keep well for up to 4 days.

Reheat gently on the stove over low heat, adding a splash of water if the sauce thickens too much.

For longer storage, freeze in meal-size portions for up to 3 months. Thaw overnight in the fridge before reheating. Cooked vegetables don’t always freeze perfectly, so consider freezing just the beef and sauce, and add fresh veggies when serving.

Benefits of This Recipe

• Hands-off cooking: Minimal prep, big payoff.

  The slow cooker handles the hard part.

• Budget-friendly: Chuck roast is affordable and becomes melt-in-your-mouth tender.
• Meal-prep ready: Easy to portion, reheat, and pair with rice or veggies.
• Balanced flavor: Sweet, savory, and umami with bright notes from vinegar and ginger.
• Flexible: Works with different cuts of beef and a mix of vegetables.

What Not to Do

• Don’t skip trimming fat: Too much fat can make the sauce greasy.
• Don’t overdo the salt: Regular soy sauce is salty. Use low-sodium and season at the end.
• Don’t dump raw starchy veggies in early: Potatoes or thick-cut carrots can cloud the sauce and cook unevenly. Add them later or cook separately.
• Don’t forget the slurry: Cornstarch at the end gives you that signature teriyaki sheen.

  Add it while the liquid is hot.

• Don’t cook too short: Tough beef means it didn’t go long enough. Keep going until it yields easily to a fork.

Variations You Can Try

• Spicy teriyaki: Add 1–2 teaspoons of sriracha or gochujang to the sauce, or finish with red pepper flakes.
• Citrus twist: Stir in the zest of 1 orange and a splash of orange juice for a bright, fruity note.
• Garlic-lover’s version: Increase garlic to 6–8 cloves and add a pinch of black pepper.
• Veggie-forward bowl: Serve with steamed bok choy, edamame, and thinly sliced cucumbers for crunch.
• No-sugar-added: Swap brown sugar for dates blended with a little hot water, or use a sugar substitute that’s heat-stable.
• Gluten-free: Use tamari or coconut aminos and check labels on broth and mirin.
• Crispy finish: After shredding, spread beef on a sheet pan and broil for 2–3 minutes to add caramelized edges before tossing back in the sauce.

FAQ

Can I make this with chicken instead of beef?

Yes. Use boneless skinless chicken thighs and cook on Low for 4–6 hours or High for 2–3 hours.

Shred, thicken the sauce as directed, and return the chicken to coat.

Do I need to brown the beef first?

No, it’s optional. Browning adds a deeper flavor, but the recipe works well without it. If you have time, sear the beef in a hot skillet with a little oil for 2–3 minutes per side before adding it to the slow cooker.

What can I use instead of cornstarch?

Arrowroot powder works well.

Use the same amount and mix with cold water before adding. It thickens a bit faster, so watch the sauce and turn off the heat once glossy.

How do I keep the sauce from getting too sweet?

Start with the listed sugar amount and taste at the end. Balance sweetness with a splash of rice vinegar or lime juice, or add a bit more soy sauce to deepen the savory notes.

What’s the best cut of beef for this?

Beef chuck roast is ideal because it has enough marbling to stay juicy and tender.

Brisket and short ribs also work, while flank steak cooks faster and stays sliceable rather than shreddable.

Can I cook this overnight?

Yes, on Low for 6–8 hours works well. Set the slow cooker before bed and thicken the sauce in the morning. Store in the fridge and reheat for dinner.

How can I reduce the sodium?

Use low-sodium soy sauce and low-sodium broth.

Do not add salt until the end. You can also cut the soy sauce with extra water and a bit more garlic and ginger.

Is mirin necessary?

No. It adds a subtle sweetness and shine, but you can replace it with honey or skip it entirely.

The sauce will still be tasty and well-balanced.

Can I add pineapple?

Sure. Add pineapple chunks in the last 30 minutes so they stay juicy. You can also use a splash of pineapple juice in the sauce for a tropical twist.
