This 5-ingredient slow cooker supper is the kind of old-fashioned dinner that earns its place in a busy family routine, especially during a summer heatwave when nobody wants the oven on. It has that cozy 1950s Sunday evening feel: simple pantry ingredients, a long gentle cook, and a rich savory sauce that makes the whole meal taste like you fussed far more than you really did.
Serve this tender, saucy main dish over mashed potatoes, buttered egg noodles, or fluffy white rice to catch every bit of the golden gravy. A side of green beans, glazed carrots, or a chilled cucumber salad keeps the plate balanced, and soft dinner rolls are always welcome for soaking up the extra sauce.
5-Ingredient Slow Cooker 1950s Sunday Evening Supper
Servings: 6
Ingredients
2 1/2 to 3 pounds slow-roast-friendly protein pieces
1 packet dry onion soup mix
1 can (10 1/2 ounces) condensed cream of mushroom soup
1 cup golden-style bottled gravy or sauce
1 tablespoon cornstarch mixed with 2 tablespoons cold water, optional for thickening
Directions
1. Lightly coat the inside of your slow cooker with cooking spray if you like easier cleanup. Arrange the protein pieces in an even layer in the slow cooker.
2. In a medium bowl, stir together the dry onion soup mix, condensed cream of mushroom soup, and golden gravy or sauce until mostly smooth. Spoon and spread the mixture over the protein.
3. Cover and cook on LOW for 6 to 8 hours or on HIGH for 3 to 4 hours, until the protein is very tender and the sauce is hot and bubbling.
4. If you want a thicker sauce, stir in the cornstarch mixture during the last 20 to 30 minutes of cooking, then cover again and let the sauce thicken.
5. Gently spoon the protein and sauce onto plates or a serving platter and serve hot with mashed potatoes, noodles, or rice.
Variations & Tips
For picky eaters: Keep the sauce very smooth by whisking it well before adding it to the slow cooker. Serving the supper over noodles or mashed potatoes can make the flavors feel extra familiar and kid-friendly.
Make it extra savory: Add a handful of sliced mushrooms or a small sliced onion if you do not mind stretching beyond the 5-ingredient idea. They melt right into the sauce and give the dish even more old-fashioned supper flavor.
For easier serving: Let the finished dish rest with the lid off for 5 to 10 minutes before serving. The sauce settles a bit, and it is easier to spoon neatly over potatoes or rice.
Leftover idea: Chop or shred the extra protein and warm it with some of the sauce the next day for open-faced sandwiches, toasted buns, or spooned over leftover rice for an easy lunch.
