How To Make Crock Pot Beef Lo Mein
- Prepare the slow cooker: Line the insert with a slow cooker liner for easier cleanup.
- Add the beef: Place beef chunks at the bottom of the slow cooker.
- Make and add the sauce: Whisk all sauce ingredients together in a bowl. Pour over the beef to fully coat.
- Slow cook the beef: Cook on low for 6–8 hours or on high for 4–5 hours, until the beef is fully cooked.
- Add pasta and vegetables: One hour before serving, place dry spaghetti underneath the beef and layer vegetables on top.
- Finish cooking: Keep the slow cooker on low. After 45 minutes, check pasta for doneness. Cook up to 15 more minutes if needed.

Recipe Tips
- Can I use regular pasta instead of gluten-free?
Yes, just reduce the cooking time slightly and check early for doneness. - How to prevent soggy vegetables:
Add them only during the final hour to keep them tender-crisp. - Can I add other vegetables?
Absolutely. Mushrooms, baby corn, or cabbage are great additions. - How to keep pasta from sticking:
Stir the noodles gently once during the last 30 minutes to prevent clumping. - What cut of beef works best?
Chuck roast, stew meat, or flank steak all work well when slow-cooked.
