This slow cooker 5-ingredient Amish sour cream beef noodles recipe is the kind of comforting, no-fuss supper I suggest first when friends ask for something hearty and reliable. It borrows from classic Amish-style sour cream beef and noodle casseroles, but streamlines the process for a busy weeknight: you simply layer raw cubed steak in the slow cooker, dollop sour cream over the top, add just three more pantry-friendly ingredients, and let low, gentle heat do the work. The result is tender beef in a tangy, creamy sauce that soaks into egg noodles—a familiar Midwestern-style comfort dish with almost no hands-on time.
Serve the sour cream beef and noodles in warm bowls, topped with a little extra black pepper if you like. A simple side of steamed green beans, buttered peas, or a crisp green salad balances the richness nicely. I also like a slice of crusty bread or soft dinner rolls to mop up the extra sauce. If you’re feeding a crowd, keep the slow cooker on “warm” and set out the cooked noodles in a covered dish so everyone can help themselves.
Slow Cooker Amish Sour Cream Beef Noodles
Servings: 6

Ingredients
2 pounds beef cubed steak, cut into bite-size pieces
1 packet (1 ounce) dry onion soup mix
1 can (10.5 ounces) condensed cream of mushroom soup
1 cup full-fat sour cream
12 ounces wide egg noodles, cooked according to package directions
Directions
Place the raw cubed steak pieces in an even layer on the bottom of a 5- to 6-quart slow cooker, spreading them out so they cook evenly.
Sprinkle the dry onion soup mix evenly over the raw cubed steak, letting the seasoning fall down between the pieces.
Spoon the condensed cream of mushroom soup over the steak and soup mix. Do not dilute the soup; you want it thick so it turns into a rich sauce as it cooks.
Using a spoon or small spatula, dollop the sour cream over the raw cubed steak and soup layer in several generous spoonfuls, as you would for a casserole. There’s no need to stir; the sour cream will melt down into the sauce as it cooks.
Cover the slow cooker with the lid and cook on LOW for 6 to 8 hours, or on HIGH for 3 to 4 hours, until the beef is very tender and the sauce is bubbling around the edges.
Near the end of the cooking time, taste the sauce and adjust seasoning if needed with a pinch of salt and black pepper, keeping in mind the onion soup mix is already salty.
About 20 minutes before serving, cook the egg noodles in a large pot of salted boiling water according to package directions until just tender. Drain well.
Gently stir the beef and sour cream sauce together in the slow cooker so everything is evenly combined, then either spoon the mixture over individual portions of egg noodles or stir the drained noodles directly into the slow cooker to coat them in the sauce.
Serve the sour cream beef and noodles hot, straight from the slow cooker, with extra black pepper or a sprinkle of fresh parsley if desired.
Variations & Tips
For a slightly lighter version, you can use light sour cream, though full-fat gives the most stable, silky sauce. If you prefer a stronger mushroom flavor, swap the cream of mushroom soup for a roasted garlic mushroom variety, or add a handful of sliced fresh mushrooms on top of the beef before cooking (this keeps you at five core ingredients if you omit any optional garnishes). To echo the Amish casserole style even more, stir in a handful of shredded Swiss or mild cheddar cheese at the very end until just melted. If you like extra sauce, add up to 1/2 cup water or beef broth to the slow cooker before cooking; this will give you more to soak into the noodles. For a touch of brightness, finish with a spoonful of prepared horseradish or a squeeze of lemon juice stirred into the sauce just before serving. Leftovers reheat well on the stovetop over low heat with a splash of water or broth to loosen the sauce.
