Total Time:5 20

Ingredients

1½ pounds flank steak thinly sliced against the grain
1 tablespoon oil
1 small onion thinly sliced
2 cups beef broth
½ cup soy sauce
¼ cup brown sugar
1 teaspoon ground ginger
1 teaspoon black pepper
3 cloves garlic minced
1 cup shredded carrots
1 cup sliced bell peppers
1 cup broccoli florets
1 cup snow peas
12 ounces lo mein noodles udon noodles or fettuccine, cooked and drained
½ tablespoon cornstarch
Scallions and sesame seeds for garnish

Instructions

Step 1: Sear the Beef - Heat the oil in a skillet over medium heat. Add the thinly sliced flank steak and quickly sear it just until the outside is browned. You are not trying to cook it through here, just giving it a little color and flavor. Transfer the beef to your slow cooker.
Step 2: Build the Sauce - Add the onion, beef broth, soy sauce, brown sugar, ground ginger, black pepper, and minced garlic right into the slow cooker with the beef. Give everything a gentle stir so the beef is coated and the flavors start to mingle.
Step 3: Add the Early Vegetables - Stir in the shredded carrots and sliced bell peppers. These can handle the longer cooking time and will soften nicely while still keeping some texture.
Step 4: Slow Cook Until Tender - Cover and cook on low for 4 to 5 hours, until the beef is tender and the sauce smells like something you would happily order from your favorite takeout place.
Step 5: Add the Quick Cook Veggies - Stir in the broccoli florets and snow peas. These go in later so they stay bright and slightly crisp instead of turning mushy.
Step 6: Thicken the Sauce - In a small bowl, mix the cornstarch with ½ tablespoon cold water until smooth. Stir this into the slow cooker. This step helps the sauce thicken so it clings to the noodles instead of pooling at the bottom.
Step 7: Add the Noodles - Gently fold in the cooked noodles. Take your time here so you do not break them up too much. You want everything coated in that savory sauce.
Step 8: Heat and Serve - Let everything heat through for about 15 to 20 minutes. Taste and adjust seasoning if needed, then top with scallions and sesame seeds if you like. Serve warm and enjoy that cozy feeling of dinner being done.

Notes

Substitutions

Sirloin steak instead of flank steak: Sirloin is a great option if that is what you have on hand and it stays tender when sliced thin.
Low sodium soy sauce: This helps keep the dish from getting too salty, especially if you are sensitive to sodium.
Ramen or spaghetti noodles: These work surprisingly well if lo mein noodles are hard to find in your area.

Variations

Add baby corn or water chestnuts: These bring extra crunch and a fun texture to the dish.
Make it spicy: A spoonful of chili paste or sriracha gives it a little kick for heat lovers.
Swap the protein: Chicken or shrimp can be used instead of beef for a different spin on the same cozy idea.

Tips and Tricks

Slice against the grain: This keeps the beef tender and easy to chew.
Add vegetables later: Quick cooking veggies go in near the end so they stay crisp tender.
Toss noodles gently: This keeps them from breaking apart and turning mushy.
Taste before serving: Everyone’s soy sauce is different so a quick taste lets you adjust salt or sweetness if needed.

Serving Ideas

Serve with a simple side salad: Something fresh balances the richness of the noodles.
Add a side of steamed dumplings: Makes the meal feel like a full takeout night at home.
Top with a soft fried egg: This is not traditional but it is cozy and delicious.
Serve family style: Put the slow cooker right on the table and let everyone help themselves.

Storage and Make Ahead Tips

Refrigerate leftovers: Store in an airtight container for up to 3 days.
Reheat gently: Warm on the stove or in the microwave with a splash of beef broth to loosen the noodles.
Make the sauce ahead: You can prep the sauce ingredients the night before to save time in the morning.
