This slow cooker potato recipe transforms humble russet potatoes into a savory, melt-in-your-mouth side dish with minimal effort. The magic of Lipton onion soup mix creates layers of flavor that simply can't be achieved any other way, making everyday potatoes extraordinary.

I discovered this recipe when my oven broke down right before hosting Sunday dinner. What started as a desperate solution has become our family's most requested potato dish. My mother-in-law even asked for the recipe, which says everything about how good these potatoes really are.

Ingredients

  • Russet potatoes these starchy potatoes break down beautifully in the slow cooker, absorbing all the flavors while maintaining just enough structure
  • Lipton onion soup mix the secret weapon that infuses deep savory flavor throughout the dish without chopping a single onion
  • Olive oil creates richness and helps the potatoes develop a slight crust around the edges where they touch the slow cooker
  • Garlic powder adds a subtle aromatic note that complements the onion perfectly
  • Black pepper provides a gentle heat that balances the sweetness from the slow-cooked onions

How To Make Slow Cooker Lipton Onion Potatoes

Prepare the slow cooker
Coat the interior thoroughly with cooking spray, ensuring every surface is covered to prevent sticking. This step saves frustration later when serving.
Arrange the potatoes
Slice the potatoes thinly and uniformly about 1/8 inch thick for even cooking. Place them in the slow cooker, slightly overlapping in a spiral pattern if desired for more even distribution of flavor.
Season generously
Sprinkle the onion soup mix, garlic powder, and black pepper evenly over all the potato layers. Be sure to distribute the seasonings all the way to the edges for consistent flavor.
Add the moisture
Drizzle olive oil slowly over the entire surface, allowing it to seep between the potato slices. This creates richness and helps distribute the seasonings throughout the dish.
Slow cook to perfection
Cover tightly and cook on high for 4 hours without peeking. Resist the temptation to lift the lid as this releases essential heat and moisture, extending cooking time.

The onion soup mix is truly the heart of this recipe. I once tried making these with homemade seasonings, and while good, they lacked that distinctive depth that only the Lipton mix provides. My grandmother always said some convenience foods earned their place in our pantries, and this is definitely one of them.

Make-Ahead Options

These potatoes actually improve with time as the flavors continue to develop. You can make them up to two days ahead and reheat in a covered dish in a 350°F oven for about 20 minutes until warmed through. I often make them the morning of a dinner party so they're ready when guests arrive.

Perfect Pairings

These potatoes complement almost any protein but shine particularly alongside a simple roast chicken or grilled steak. The savory flavor profile makes them versatile enough for weeknight dinners yet special enough for holiday meals. My family loves them with meatloaf and a side of green beans for a comfort food dinner that satisfies everyone.

Troubleshooting Tips

If your potatoes aren't tender after 4 hours, your slices might be too thick. Give them another 30-60 minutes. Every slow cooker heats slightly differently, so you may need to adjust timing for your particular model. Using a mandoline for slicing ensures consistent thickness and even cooking throughout.

Recipe FAQs

Aim for approximately 1/8-inch thick slices. Consistent thickness ensures even cooking, and thinner slices cook more quickly while absorbing more flavor.

Absolutely! Thinly sliced onions, carrots, or bell peppers make excellent additions. Add them alongside the potatoes at the beginning of cooking time.

→ Do I need to stir during cooking?

It's best not to stir during cooking. The recipe specifically notes to keep the lid closed throughout the cooking process for optimal results and even heat distribution.

Yes, these potatoes reheat well. Store in an airtight container in the refrigerator for up to 3 days and reheat in the microwave or oven until warmed through.
