This slow cooker Amish-style cream of celery beef is the kind of practical, comforting supper that earns a regular place in the dinner rotation. With just four ingredients, it leans on pantry convenience and low, steady cooking to turn flank steak into tender slices coated in a savory, creamy gravy. The combination is simple, old-fashioned, and especially appealing on busy days when you want a hearty meal with very little hands-on work.
Serve this beef over mashed potatoes, buttered egg noodles, or steamed white rice so none of the creamy celery gravy goes to waste. For balance, add a simple green vegetable such as steamed green beans, buttered peas, or roasted broccoli, and if you like, put a basket of warm dinner rolls on the table to round out the meal.
Slow Cooker 4-Ingredient Amish Cream of Celery Beef
Servings: 6
Ingredients
1 1/2 to 2 pounds beef flank steak
2 cans (10.5 ounces each) cream of celery soup
1 packet dry onion soup mix
1/2 cup water
Directions
1. Lightly grease the insert of a slow cooker if desired. Place the flank steak in the slow cooker, folding it if needed so it fits in an even layer.
2. In a bowl, stir together the cream of celery soup, dry onion soup mix, and water until well combined.
3. Pour the soup mixture evenly over the raw flank steak, making sure the meat is well covered.
4. Cover and cook on low for 6 to 8 hours or on high for 3 to 4 hours, until the beef is very tender.
5. Transfer the beef to a cutting board, slice it thinly against the grain, then return it to the slow cooker and spoon the gravy over the top before serving.
Variations & Tips
Add mushrooms: For a deeper, earthier flavor, scatter 8 ounces of sliced mushrooms around and over the steak before adding the soup mixture. They cook down nicely and make the gravy feel even heartier.
Make it over noodles: If you plan to serve this over egg noodles, keep the sauce slightly looser by adding an extra 1/4 cup water. Noodles absorb gravy quickly, so the extra liquid helps the dish stay creamy on the plate.
Use the right slicing method: Flank steak stays most tender when sliced thinly against the grain after cooking. If you prefer, you can also shred the beef lightly with two forks and stir it back into the sauce for a softer texture.
Season at the end: Because canned soup and onion soup mix already contain plenty of salt, wait until the beef is cooked before deciding whether it needs any additional seasoning. A little black pepper at the table is often all it needs.
Thicken the gravy if needed: If the sauce seems thinner than you like, leave the lid off for 15 to 20 minutes on high after slicing the beef back into the cooker. You can also stir in a small cornstarch slurry at the end for a thicker, spoonable gravy.
