Can I use a different cut of beef for Crockpot Beef Lo Mein?

Absolutely. While sirloin gives the best balance of tenderness and flavor, flank steak or even thin-sliced chuck roast works just as well. The key is slicing the beef thin against the grain so it becomes soft and juicy after slow cooking.

Can I cook this recipe on HIGH instead of LOW?

Yes, but only if you’re short on time. Cooking on HIGH for 2 ½ – 3 hours will still yield delicious results, though the flavor deepens more fully on LOW over 4 – 5 hours. Slow heat allows the sauce and beef to meld beautifully.

What noodles work best for Crockpot Beef Lo Mein?

Lo Mein noodles are the traditional choice, but spaghetti or linguine can be excellent substitutes. If you like a slightly chewy texture, try rice noodles or udon. Just remember to cook them al dente before adding them to the crockpot during the last 20 minutes.

How can I thicken the sauce if it’s too watery?

If the sauce feels too thin after cooking, stir in a quick cornstarch slurry (1 tablespoon cornstarch + 2 tablespoons cold water) and cook uncovered for about 10 minutes. The sauce will tighten up into that perfect glossy coating.

Description

This Crockpot Beef Lo Mein brings takeout-style flavor straight to your slow cooker. Tender slices of beef, soft noodles, and colorful veggies soak up a rich, savory sauce that’s glossy, satisfying, and unbelievably easy to make at home.

Ingredients

1 ½ lbs beef sirloin, thinly sliced

3 cups beef broth

¼ cup soy sauce

2 tbsp brown sugar

1 tbsp sesame oil

3 cloves garlic, minced

1 tsp ground ginger

1 red bell pepper, sliced

1 cup shredded carrots

8 oz lo mein noodles or spaghetti

Green onions and sesame seeds for topping

Instructions

1. Place the sliced beef into your crockpot.

2. Whisk together the beef broth, soy sauce, brown sugar, sesame oil, garlic, and ginger in a bowl.

3. Pour the sauce mixture over the beef.

4. Add the sliced red bell pepper and shredded carrots on top.

5. Cover and cook on LOW for 4–5 hours until the beef is tender.

6. Stir in the noodles during the final 20–25 minutes of cooking until soft and coated in sauce.

7. Top with green onions and sesame seeds before serving.

Notes

For a bit of spice, add a dash of chili flakes or sriracha.

Use spaghetti noodles if you can’t find lo mein noodles — they absorb the sauce beautifully.

To prevent overcooked noodles, add them near the end and stir gently.

Leftovers reheat perfectly for next-day lunches.

Serve with steamed broccoli or a side of egg rolls for a complete meal.
