A slow cooker can turn five everyday ingredients into a generous, comforting pasta dinner. This version combines savory ground beef, sweet onion, tomato sauce, tender egg noodles, and a blanket of melted mozzarella. Most of the cooking is hands-off, and the noodles go in near the end so they stay pleasantly tender.
Why You’ll Love This Slow Cooker Pasta
The beef and onion simmer in the sauce for hours, giving a simple jarred sauce a richer, home-cooked flavor. Egg noodles cook directly in the slow cooker, absorbing that sauce instead of needing a separate pot. Add the cheese just before serving and you have a bubbling, family-style meal with very little cleanup.
This recipe serves six and works well for a busy evening. Brown the meat in advance if you like, refrigerate it promptly, then transfer it to the slow cooker when you are ready to begin.
Ingredients
- 1 pound ground beef: Brown it fully and drain excess fat before it goes into the slow cooker.
- 1 medium onion, finely chopped: Cooking it with the beef softens its flavor.
- 1 jar (24 ounces) pasta sauce: Choose a tomato sauce you enjoy; marinara works beautifully.
- 8 ounces uncooked egg noodles: Add them only during the final stage of cooking.
- 1 cup shredded mozzarella: Sprinkle it over the hot pasta and let it melt under the lid.
Water is useful for adjusting the sauce if the noodles need more moisture; it does not add another flavor ingredient.
How to Make Slow Cooker 5-Ingredient Pasta Waldorf
1. Brown the beef and onion
Put a skillet over medium heat. Cook the ground beef and chopped onion together, breaking up the meat, until the beef is no longer pink and the onion has softened. Drain off excess grease. This brief stovetop step gives the finished dish a better texture and keeps it from becoming oily.
2. Simmer in the sauce
Transfer the beef and onion to the slow cooker. Pour in the pasta sauce and stir so the meat is evenly coated. Cover and cook on LOW for 3 hours. The gentle simmer allows the beef and onion to flavor the sauce without drying out the meat.
3. Cook the egg noodles
Stir the uncooked egg noodles into the sauce, pressing them down so they are coated. Cover and switch the slow cooker to HIGH for 20 to 30 minutes. Start checking at 20 minutes: slow cookers vary, and the noodles are ready when tender but not mushy. If the mixture seems too thick or the noodles are not submerged enough to soften, stir in a small splash of water and cover again.
4. Melt the mozzarella
Once the noodles are tender, scatter the shredded mozzarella over the pasta. Replace the lid for 5 to 10 minutes, just until the cheese melts. Spoon the pasta into bowls while it is hot and creamy. A green salad or steamed vegetables make easy sides.
Variations & Tips
- For picky eaters: Chop the onion very finely so it blends into the sauce. Stir the melted cheese through the pasta rather than leaving it on top.
- Swap the protein: Ground turkey or mild Italian sausage can take the place of beef. Cook either fully in the skillet before adding it to the slow cooker.
- Try another short pasta: Small shells or rotini can work, but their cooking time and liquid needs may differ. Check early and add water a little at a time.
- Avoid overcooked noodles: Add them only at the end, begin testing at 20 minutes, and serve soon after they become tender.
- Prepare ahead: Brown the beef and onion the night before, cool and refrigerate them, and add them with the sauce when you start the slow cooker.
Storage and Reheating
Refrigerate leftovers in a covered container within two hours and use them within three to four days. The noodles will absorb more sauce as they sit. Reheat gently with a splash of water, stirring until the pasta is hot throughout. For the best texture, enjoy this dish fresh; freezing cooked egg noodles can make them soft after thawing.
