A slow cooker is a fantastic way to make tender, buttery potatoes infused with sweet, jammy caramelized onions. Because true caramelization requires direct heat and evaporation over a skillet, the best method for the slow cooker is a layered approach where the onions and butter melt slowly around the potatoes, creating a rich, savory glaze.
Here is a delicious, comforting recipe for **Slow Cooker Layered Potatoes and Caramelized Onions**.
—
### **Ingredients**
* **2 lbs Yukon Gold or baby potatoes** (sliced into 1/4-inch rounds or halved if using small baby potatoes)
* **2 large yellow or sweet Vidalia onions**, thinly sliced
* **4 tbsp unsalted butter**, melted
* **1 tbsp olive oil** (helps prevent the butter from burning and adds flavor)
* **1 tsp garlic powder**
* **1 tsp salt** (or to taste)
* **1/2 tsp black pepper**
* *Optional enhancement:* 1/2 tsp brown sugar or a splash of balsamic vinegar (to deepen the sweetness of the onions)
* *Optional finish:* Shredded cheddar or grated Parmesan cheese, and fresh chopped parsley

### **Instructions**
1. **Prep the Slow Cooker:** Lightly grease the inside of your slow cooker insert with non-stick spray or a bit of olive oil.
2. **Layer the Ingredients:**
* Place **half of the sliced potatoes** in an even layer at the bottom of the slow cooker.
* Scatter **half of the thinly sliced onions** evenly over the potatoes.
* Drizzle with **half of the melted butter and olive oil mixture**. Season with a pinch of your salt, pepper, and garlic powder.
* Repeat the layers: Add the remaining potatoes, remaining onions, rest of the butter/oil, and the remaining seasonings.
3. **Cook Low and Slow:**
* Cover and cook on **LOW for 6 to 7 hours** or on **HIGH for 3 to 4 hours**.
* *Note:* Avoid opening the lid too often, as you want the slow cooker to trap the heat and steam, rendering the potatoes fork-tender and the onions soft and sweet.
4. **Toss and Serve:**
* Once cooking is complete, use a large spoon to gently toss and stir everything together. The onions will have broken down into a rich, buttery, jammy sauce that coats the tender potatoes.
* If desired, sprinkle cheese or fresh herbs over the top during the last 10 minutes of cooking until melted.

### **Pro Tips for Success**
* **Potato Choice:** Yukon Golds are ideal because they have a naturally buttery flavor and hold their shape well without turning completely mushy.
* **Extra-Rich Flavor:** If you want a deeper, more traditional “caramelized” brown color on the onions, you can sauté the sliced onions in a skillet on the stove for 15 minutes before tossing them into the slow cooker with the raw potatoes.
