5-Ingredient Slow Cooker National Dog Day Potatoes
Servings: 6 to 8
Ingredients
1 (5-ounce) box dry au gratin potatoes, including sauce packet
Directions
1. Lightly grease the inside of a 4- to 6-quart slow cooker. Pour in the dry potatoes from the box and the sauce packet.
2. Add the sliced smoked sausage, shredded cheddar cheese, milk, and sour cream. Stir gently until everything is evenly combined.
3. Cover and cook on low for 4 to 5 hours, stirring once or twice if your slow cooker cooks hot, until the potatoes are tender and the sauce is thick and creamy.
4. Give the potatoes a final stir, then spoon into a serving bowl or serve straight from the slow cooker. If you like, let them rest for 5 to 10 minutes to thicken a bit more before serving.
Variations & Tips
Kid-Friendly Version: For picky eaters, use mild cheddar and slice the sausage into smaller bite-size pieces so every spoonful is easy to eat. This is also a nice way to stretch the dish for younger kids at the table.
Make It Meatless: Skip the sausage and add a little extra cheese for a simple cheesy potato side dish that goes with almost anything from grilled vegetables to sandwiches.
Extra Flavor: If you have a little more room in the budget and do not mind stepping beyond five ingredients, a sprinkle of garlic powder, black pepper, or chopped chives right before serving adds nice flavor without extra work.
Watch the Liquid: Different boxed potato brands can absorb liquid a little differently, so check the potatoes near the end of cooking. If the mixture looks too thick before the potatoes are tender, stir in a splash of milk.
For Potlucks: Keep the slow cooker on the warm setting after cooking and stir before serving. This dish travels well and stays comforting and creamy for sharing with friends.
