Ingredients
- 2.5 lbs Yukon Gold potatoes, peeled and thinly sliced (about 1/8-inch thick)
- 2 large yellow onions, peeled and thinly sliced
- 4 tablespoons unsalted butter, melted
- 1 cup vegetable broth or chicken broth
- 1 teaspoon dried thyme
- 1/2 teaspoon garlic powder
- 1 teaspoon salt
- 1/2 teaspoon freshly ground black pepper
- Optional: 1/4 cup fresh parsley, chopped, for garnish
Instructions
- Prepare your slow cooker: Lightly grease the inside of a 6-quart slow cooker with butter or cooking spray to prevent sticking. For easier cleanup, you can also line it with a slow cooker liner or parchment paper, ensuring the parchment paper extends up the sides.
- Slice the vegetables: Peel the potatoes and slice them into thin, uniform rounds, approximately 1/8-inch thick. A mandoline slicer works wonders for achieving consistent thickness, which is key for even cooking. Peel and thinly slice the onions into similar 1/8-inch rounds or half-moons.
- Layer the first potato layer: Place about one-third of the sliced potatoes in an even layer at the bottom of the prepared slow cooker.
- Add the first onion layer: Spread half of the sliced onions evenly over the potato layer.
- Season and butter: Drizzle about one-third of the melted butter over the onions and potatoes. Sprinkle with 1/3 teaspoon of salt, 1/4 teaspoon of black pepper, 1/3 teaspoon of dried thyme, and 1/6 teaspoon of garlic powder.
- Repeat layering: Add another one-third of the sliced potatoes over the onion layer. Follow with the remaining half of the sliced onions. Drizzle with another one-third of the melted butter and sprinkle with another 1/3 teaspoon of salt, 1/4 teaspoon of black pepper, 1/3 teaspoon of dried thyme, and 1/6 teaspoon of garlic powder.
- Final potato layer: Top with the remaining one-third of the sliced potatoes, creating the final layer. Drizzle with the remaining melted butter.
- Add broth and final seasoning: Pour the vegetable or chicken broth carefully over the layered potatoes and onions. Sprinkle the remaining 1/3 teaspoon of salt, 1/4 teaspoon of black pepper, 1/3 teaspoon of dried thyme, and 1/6 teaspoon of garlic powder evenly over the top layer.
- Cook: Cover the slow cooker with its lid. Cook on LOW for 6-8 hours or on HIGH for 3-4 hours, or until the potatoes are fork-tender and the onions are deeply caramelized and soft. Cooking times can vary depending on your slow cooker, so check for tenderness around the lower end of the cooking range.
- Serve: Once cooked, carefully remove the lid. If desired, you can gently stir the bake to combine some of the caramelized onions with the potatoes, or serve it directly from the slow cooker. Garnish with fresh chopped parsley, if using, for a fresh burst of color and flavor. Serve hot as a delicious side dish or a light vegetarian main.
Cooking Tips and Variations
For the most tender and evenly cooked results, consistency in your potato and onion slices is key. A mandoline slicer is a fantastic tool for achieving uniform 1/8-inch thick slices, ensuring everything cooks through at the same rate. If you don’t have one, just take your time with a sharp knife. To prevent your potatoes from sticking to the bottom of the slow cooker, a good layer of grease or a slow cooker liner is highly recommended. You can also place a few extra slices of onion directly on the bottom before the first potato layer, as their moisture can help prevent sticking.
Elevate your Slow Cooker Potato and Onion Bake with these delicious variations. For a richer, creamier texture, consider adding 1/2 cup of heavy cream or half-and-half along with the broth during the last hour of cooking. If you’re a cheese lover, sprinkle 1 cup of shredded Gruyere, cheddar, or Parmesan cheese over the top during the last 30-45 minutes of cooking, allowing it to melt into a gooey, golden crust. For a smoky flavor, crisp up 4-6 slices of bacon, crumble them, and sprinkle them over the top before serving, or even layer some uncooked bacon bits between the potato layers for flavor infusion during cooking. Incorporate other fresh herbs like rosemary or sage for an aromatic twist, or amp up the garlic flavor by adding 2-3 cloves of minced fresh garlic to the layers. This dish is incredibly versatile, so feel free to experiment with your favorite seasonings and additions.
When it comes to serving, this bake is a chameleon. It’s phenomenal alongside classic roast chicken, juicy grilled steaks, or tender pork chops. For a heartier vegetarian meal, pair it with a simple green salad dressed with a vinaigrette, or serve it with some sautéed mushrooms or a fried egg on top. The caramelized onions and tender potatoes also make it a fantastic brunch item. Remember, while stirring typically isn’t needed during slow cooking, if you notice the edges are getting too browned or dry, a gentle stir midway through can help redistribute moisture and ensure even cooking. Always ensure your slow cooker lid fits snugly to maintain consistent heat and moisture.
Storage and Reheating
This Slow Cooker Potato and Onion Bake makes for wonderful leftovers, often tasting even better the next day as the flavors have more time to meld. To store, allow the bake to cool completely to room temperature. Transfer the leftovers to an airtight container and refrigerate promptly. It will keep well in the refrigerator for up to 3-4 days. It’s important to cool it quickly to prevent bacterial growth; avoid leaving it out on the counter for more than two hours.
For reheating, you have a few excellent options. The microwave is the quickest method: place a single serving in a microwave-safe dish, cover loosely, and heat on high for 1-2 minutes, or until thoroughly heated through, stirring halfway. For a more even reheat and to revive some of the texture, the oven is your best bet. Preheat your oven to 350°F (175°C). Transfer the desired amount of the potato and onion bake to an oven-safe dish, cover it with foil to prevent drying out, and bake for 15-25 minutes, or until hot in the center. If you want to crisp up the top slightly, remove the foil for the last 5-10 minutes. You can also reheat smaller portions in a skillet on the stovetop over medium-low heat, stirring occasionally, until warmed through. Add a splash of broth or water if it seems too dry during reheating.
Frequently Asked Questions
What kind of potatoes are best for this bake?
Yukon Gold potatoes are highly recommended for this Slow Cooker Potato and Onion Bake because of their creamy texture and slightly buttery flavor. They hold their shape well when sliced thin but become incredibly tender when slow-cooked. Other good options include red potatoes or even Russets, though Russets might break down a bit more and create a softer, almost mashed-like texture in places.
Can I add cheese to this recipe?
Absolutely! Adding cheese is a fantastic variation. For the best results, sprinkle about 1 to 1.5 cups of shredded cheese (such as Gruyere, sharp cheddar, Parmesan, or a blend) over the top of the potato and onion bake during the last 30-45 minutes of cooking. This allows the cheese to melt beautifully and form a delicious, golden crust. You can also add thin slices of cheese between the layers if you prefer a more integrated cheesy flavor throughout.
Can I make this bake ahead of time?
Yes, you can certainly prepare parts of this bake ahead of time. You can slice the potatoes and onions a day in advance and store them separately in airtight containers in the refrigerator. If you’ve sliced the potatoes, submerge them in cold water to prevent browning, then drain and pat them very dry before layering. You can also assemble the entire bake in the slow cooker insert, cover it, and refrigerate it overnight. When ready to cook, simply place the insert back into the slow cooker base and proceed with the cooking instructions. Just be aware that cooking time might be slightly longer if starting from a chilled state.
Why are my potatoes still hard after cooking?
If your potatoes are still hard, it’s likely due to one of a few reasons: the slices might be too thick, the cooking time wasn’t long enough, or your slow cooker might run cooler than average. Ensure your potato slices are consistently thin (about 1/8-inch). If they are thicker, they will require a longer cooking time. Always check for tenderness with a fork. If they’re not done, simply put the lid back on and continue cooking for another 30-60 minutes, checking periodically. You might also want to ensure your slow cooker is functioning properly and maintaining the correct temperature.
