Ingredients

The beauty of this dish lies in its simplicity. You don’t need a long grocery list to create something delicious. Here are the key players:

The Core Ingredients

• Potatoes: 2 to 3 pounds. Yukon Gold or Red Potatoes are the best choices here. They have a waxy skin and creamy interior that holds its shape better during long cooking times compared to Russets, which can become mealy and fall apart.
• Lipton Onion Soup Mix: 1 packet (1 ounce). This is the flavor powerhouse. It contains dehydrated onions, beef bouillon, and savory spices that rehydrate in the slow cooker to create a rich sauce.
• Cooking Oil: 1/3 cup. Olive oil or vegetable oil works well. This helps coat the potatoes and distribute the seasoning evenly.
• Butter: 1/4 cup (half a stick), melted. While oil prevents sticking, butter adds that essential rich, creamy mouthfeel and flavor that pairs so perfectly with potatoes.

Optional Aromatics & Garnish

• Garlic: 2 cloves, minced. Fresh garlic amplifies the savory notes of the onion mix.
• Fresh Thyme or Parsley: Chopped. Adding fresh herbs at the end brightens up the dish and adds a pop of color to the brown and gold tones.
• Black Pepper: To taste. You likely won’t need extra salt due to the soup mix, but a crack of fresh pepper adds nice heat.

Step-by-Step Instructions

Follow these steps to ensure your potatoes come out perfectly tender and flavorful every time.

1. Prepare the Potatoes

Wash and scrub your potatoes thoroughly. You can peel them if you prefer, but leaving the skins on adds texture, color, and nutrients—especially if using red or Yukon gold potatoes. Slice the potatoes into even rounds, approximately 1/4 to 1/2 inch thick. Uniform slicing is key to ensuring they all cook at the same rate.

2. Mix the Seasoning

In a small bowl, whisk together the olive oil and melted butter. In a very large mixing bowl, place your sliced potatoes. Drizzle the oil/butter mixture over the potatoes. Open the packet of Lipton Onion Soup Mix and sprinkle it evenly over the potatoes. Toss everything together with your hands or a large spoon until every single slice is coated in the glossy, speckled mixture.

3. Layer in the Slow Cooker

Grease the insert of your slow cooker lightly with non-stick spray or a little butter. Pour the coated potatoes into the slow cooker. Try to spread them out as much as possible, though overlapping is inevitable and fine. If you have extra seasoning left in the bowl, scrape it out with a spatula and drizzle it over the top.

4. Slow Cook

Place the lid on the slow cooker. You have two options for cooking times depending on your schedule:

• High Heat: Cook for 3 to 4 hours. This is best if you are starting around noon for an early dinner.
• Low Heat: Cook for 6 to 7 hours. Perfect for starting in the morning before work.

Note: Stir the potatoes gently halfway through the cooking time if possible. This helps rotate the potatoes from the bottom (where it’s hottest) to the top, ensuring even cooking and preventing the bottom layer from burning.

5. Check for Doneness

The potatoes are done when they are fork-tender. A fork should slide easily into the center of a thick slice with no resistance. If they are still hard, cover and cook for another 30 minutes.

6. Garnish and Serve

Once tender, give them a final gentle toss to coat them in the juices that have gathered at the bottom. Transfer to a serving dish and sprinkle generously with fresh thyme or parsley. Serve hot.

Tips for Success

While this recipe is incredibly simple, a few expert tips can take it from “good” to “unforgettable.”

• Uniform Slicing: Using a mandoline slicer is the best way to get perfectly even slices. This prevents having some potatoes that are mushy while others are still raw.
• Avoid Mushiness: If you are using Russet potatoes, cut them into chunks rather than thin slices, as they break down faster. Yukon Golds are more forgiving for slices.
• Crispy Edges Hack: Slow cookers are great for tenderizing, but not for crisping. If you miss that roasted texture, spread the cooked potatoes onto a baking sheet and broil them in the oven for 3-5 minutes before serving. This gives you the best of both worlds: soft interiors and crispy, caramelized edges.
• Seasoning Control: The soup mix can be salty. If you are sensitive to salt, use unsalted butter and do not add any additional table salt until you have tasted the finished dish.

Variations to Try

Customizing this dish is easy. Here are a few popular twists on the classic recipe:

Cheesy Onion Potatoes

In the last 20 minutes of cooking, sprinkle 1 cup of shredded cheddar or Gruyère cheese over the top of the potatoes. Replace the lid and let the cheese melt into a gooey blanket. The sharp cheese pairs beautifully with the onion flavor.

Loaded Bacon Potatoes

Cook 4-6 strips of bacon until crispy and crumble them. Stir the bacon bits into the potatoes right before serving, or sprinkle them on top along with chopped green onions and a dollop of sour cream.

Creamy Style

For a scalloped potato vibe, mix 1/2 cup of sour cream or heavy cream with the soup mix and butter before tossing with the potatoes. This creates a creamy, rich sauce rather than an oily glaze.

Serving Suggestions

These Lipton Onion Potatoes are versatile enough to go with almost any main protein. Here are some of our favorite pairings:

• Classic Meatloaf: The onion flavor in the potatoes echoes the savory notes in a traditional meatloaf perfectly.
• Roast Chicken: Serve these alongside a lemon-herb roasted chicken and green beans for a complete Sunday dinner.
• Grilled Steak: Skip the fries and serve these tender, savory potatoes with your favorite cut of beef.
• Holiday Ham: The saltiness of the ham and the savory onion potatoes are a match made in heaven.

Storage and Reheating

Storage: Leftovers can be stored in an airtight container in the refrigerator for up to 4 days. The flavors actually meld even more as they sit!

Reheating: To reheat, you can use the microwave, but for best results, reheat them in a skillet on the stove over medium heat. This allows you to crisp up the edges slightly, reviving the texture.

Freezing: Freezing is not recommended for this dish. Cooked potatoes tend to become watery and grainy when frozen and thawed due to their high starch content.
