Instructions

  1. How to Prepare Slow Cooker Beef and Noodles

    Prepare Beef & Onions → Mix Sweet & Tangy Sauce → Slow Cook → Shred Beef → Thicken Sauce → Serve Over Noodles!

  1. Prepare the Beef & Onions

    Season the chuck roast on all sides with kosher salt and black pepper. Arrange the sliced onions in the bottom of a 6-quart slow cooker and place the beef on top.

  1. Mix the Sweet & Tangy Sauce

    In a medium bowl, whisk together the ketchup, balsamic vinegar, soy sauce, Worcestershire sauce, Dijon mustard, brown sugar, garlic powder, and beef broth until smooth.

  1. Slow Cook

    Pour the sauce over the beef and onions. Cover and cook on LOW for 8–10 hours, or until the beef is fork-tender and easily pulls apart.

  1. Shred the Beef

    Carefully remove the roast from the slow cooker. Use two forks to break the beef into large, bite-sized chunks, lightly shredding some of the meat. Return the beef to the slow cooker and gently stir to coat it in the sauce.

  1. Thicken the Sauce

    In a small bowl, whisk the cornstarch and cold water together until smooth. Stir the slurry into the sauce, cover, and cook on HIGH for 15–20 minutes, or until the sauce is thick and glossy. Allow additional time if needed.

  1. Serve Over Noodles

    While the sauce thickens, cook the egg noodles according to package directions. Drain and toss with salted butter. Spoon the tender beef, onions, and plenty of sweet-and-tangy sauce over the noodles. Garnish with chopped parsley, if desired.

Note

Tips for Making Slow Cooker Beef and Noodles

For the best slow cooker beef and noodles, use a well-marbled chuck roast and cook on LOW until the beef is fork-tender. To create a rich, thick sauce that coats the noodles, stir in the cornstarch slurry during the last 15–20 minutes of cooking. Cook the egg noodles separately and spoon the beef and plenty of sauce over them just before serving.

Choosing the Best Beef: Boneless chuck roast is ideal for slow cooker beef and noodles because the connective tissue gradually softens during slow cooking, creating tender, flavorful meat.

Getting the Sauce Just Right: The cornstarch slurry creates a thicker sauce that coats the beef and noodles. If you prefer a thinner sauce, start with 1 tablespoon of cornstarch instead.

Adjusting the Flavor: For a sweeter sauce, stir in a little extra brown sugar. For more tanginess, add a small splash of balsamic vinegar after cooking.

Serving Suggestions: Wide egg noodles are our favorite, but this beef is also delicious over mashed potatoes or fluffy white rice.

Storage and Reheating: Refrigerate leftovers in an airtight container for 3–4 days. Store the noodles separately when possible. Reheat the beef gently, adding a splash of broth if the sauce has thickened too much.

Frequently Asked Questions

Expand All:

What is the best cut of beef for slow cooker beef and noodles?

Boneless chuck roast is the best choice because its marbling and connective tissue break down during slow cooking, creating tender, flavorful beef that easily pulls apart.

Can I cook this recipe on HIGH instead of LOW?

Yes. Cook on HIGH for approximately 4–6 hours, or until the beef is fork-tender. However, cooking on LOW for 8–10 hours is recommended for the most tender results.

How do I make the sauce thicker?

Mix 2 tablespoons of cornstarch with 2 tablespoons of cold water, then stir into the hot sauce. Cover and cook on HIGH for 15–20 minutes, or until thickened. The sauce should be thick enough to coat the beef and spoon generously over the noodles.

Can I cook the egg noodles directly in the slow cooker?

I recommend cooking the egg noodles separately. This prevents them from becoming mushy or absorbing too much of the sweet-and-tangy sauce.

Can I make slow cooker beef and noodles ahead of time?

Absolutely! The beef and sauce can be prepared a day ahead and refrigerated. Reheat gently and prepare fresh egg noodles just before serving.

Can I freeze the leftover beef?

Yes. Allow the beef and sauce to cool, then transfer to freezer-safe containers and freeze for up to 3 months for best quality. Thaw overnight in the refrigerator before reheating. For the best texture, prepare fresh egg noodles when serving.

Is this recipe very sweet?

The sauce has a balance of sweetness from ketchup and brown sugar, tanginess from balsamic vinegar, and savory flavor from soy sauce and Worcestershire sauce. For a less sweet version, reduce the brown sugar slightly.

What can I serve with sweet and tangy slow cooker beef and noodles?

This hearty dinner pairs well with roasted green beans, steamed broccoli, a simple garden salad, or warm crusty bread.
