Ingredients

For the Potatoes

• 2 pounds Yukon Gold potatoes

• 2 large yellow onions, thinly sliced

• 3 tablespoons unsalted butter, melted

• 2 tablespoons olive oil

• 3 garlic cloves, minced

For the Seasonings

• 1 teaspoon garlic powder

• 1 teaspoon onion powder

• 1 teaspoon smoked paprika

• 1 teaspoon dried Italian seasoning

• ½ teaspoon dried thyme

• ¾ teaspoon salt, or to taste

• ½ teaspoon freshly ground black pepper

For Extra Flavor

• ¼ cup low-sodium chicken broth or vegetable broth

• 1 tablespoon Worcestershire sauce (optional)

• 1 tablespoon fresh chopped parsley

• 1 tablespoon additional butter for finishing (optional)

Step-by-Step Instructions

Step 1: Prepare the Slow Cooker

Lightly grease the inside of a 4–6-quart slow cooker with butter or nonstick cooking spray.

This prevents the potatoes from sticking and makes cleanup easier.

Make sure the slow cooker is clean and dry before adding the ingredients.

Step 2: Wash and Slice the Potatoes

Wash the Yukon Gold potatoes thoroughly under running water.

You can leave the skins on for a rustic appearance or peel them if you prefer a smoother texture.

Slice the potatoes into approximately ¼-inch-thick rounds.

Try to keep the slices evenly sized so they cook at the same rate.

Avoid slicing them too thinly because they may break apart during slow cooking.

Step 3: Prepare the Onions

Peel the yellow onions and slice them into thin half-moons.

Separate the onion slices gently with your fingers.

Yellow onions work particularly well because they become naturally sweet and tender during cooking.

For a slightly sweeter flavor, you can substitute sweet onions.

Step 4: Prepare the Butter Mixture

In a small mixing bowl, combine the melted butter, olive oil, minced garlic, garlic powder, onion powder, smoked paprika, Italian seasoning, dried thyme, salt, and black pepper.

Stir until everything is evenly combined.

This seasoned butter mixture will coat the potatoes and onions, creating a delicious savory flavor.

Step 5: Layer the Potatoes and Onions

Place approximately one-third of the sliced potatoes into the bottom of the slow cooker.

Add a layer of sliced onions over the potatoes.

Drizzle a little of the seasoned butter mixture over the onions.

Repeat the layers until all the potatoes, onions, and butter mixture have been added.

Gently toss or lift the layers with a spatula to distribute the seasonings without breaking the potatoes.

Step 6: Add the Broth

Pour the chicken broth or vegetable broth around the edges of the slow cooker.

If using Worcestershire sauce, drizzle it over the potatoes.

The small amount of liquid helps create steam, allowing the potatoes to cook until tender.

Avoid adding too much broth because the potatoes and onions release moisture during cooking.

Step 7: Slow Cook Until Tender

Cover the slow cooker with its lid.

Cook on:

• LOW: 4–6 hours

• HIGH: 2½–3½ hours

Cooking times depend on the thickness of the potato slices and the slow cooker model.

The potatoes are ready when a fork slides easily through the center.

The onions should be soft, translucent, and lightly golden from the seasonings.

Keep in mind that slow cooking softens onions but does not brown them as deeply as frying.

Step 8: Gently Stir the Potatoes

Once the potatoes are tender, carefully remove the lid.

Use a wide spatula to gently turn the potatoes and onions.

Avoid stirring too vigorously because the potatoes may break apart.

Taste and adjust the salt, black pepper, or other seasonings if necessary.

Step 9: Add the Finishing Butter

For an extra-rich flavor, add 1 tablespoon of butter while the potatoes are still hot.

Allow it to melt naturally, then gently toss the potatoes.

The butter creates a beautiful glossy finish and enhances the savory flavor.

Step 10: Garnish and Serve

Sprinkle freshly chopped parsley over the potatoes and onions.

Transfer them to a serving bowl or serve directly from the slow cooker.

Enjoy warm alongside your favorite main dishes.

Tips and Notes

1. Choose the Right Potatoes: Yukon Gold potatoes are ideal because they have a naturally buttery flavor and hold their shape well. Red potatoes are another excellent choice.

2. Slice Potatoes Evenly: Uniform slices ensure the potatoes cook consistently. A mandoline slicer can make preparation easier.

3. Don’t Add Too Much Liquid: Potatoes and onions naturally release moisture during slow cooking. Excess broth can make the dish watery.

4. Use Yellow or Sweet Onions: Yellow onions provide a balanced savory flavor, while sweet onions create a milder, sweeter result.

5. Avoid Overcooking: Check the potatoes toward the end of the recommended cooking time. Overcooking may cause them to become mushy.

6. Add Extra Garlic: If you enjoy a stronger garlic flavor, add another minced garlic clove.

7. Make It Cheesy: Sprinkle shredded cheddar or Parmesan over the cooked potatoes and cover briefly until melted.

8. Add Bacon: Cooked, crumbled bacon makes a delicious addition for extra smoky flavor.

9. Create Golden Edges: For lightly browned potatoes, transfer the cooked mixture to a baking sheet and broil for 3–5 minutes, watching carefully to prevent burning.

10. Storage: Refrigerate leftovers in an airtight container within 2 hours of cooking. Store for up to 3–4 days and reheat until thoroughly hot.

Frequently Asked Questions

1. Can I Put Raw Potatoes Directly Into the Slow Cooker?

Yes! Raw sliced potatoes cook beautifully in a slow cooker. There’s no need to boil them first. Simply slice, season, and layer them with the onions.

2. Do I Need to Peel the Potatoes?

No. Yukon Gold potatoes have thin, tender skins that are perfectly suitable for this recipe. Peeling is optional.

3. Can I Use Russet Potatoes?

Yes, but Russet potatoes contain more starch and may become softer or break apart more easily. Yukon Gold or red potatoes are preferable when you want slices that hold their shape.

4. Will the Onions Caramelize in the Slow Cooker?

The onions will become soft and sweet, but they won’t develop the same deep golden color as onions cooked in a skillet. For deeper caramelized flavor, sauté the onions before adding them to the slow cooker.

5. Can I Add Other Vegetables?

Absolutely! Bell peppers, mushrooms, and sliced carrots make delicious additions. Remember that different vegetables may require slightly different cooking times.

6. Can I Make This Recipe Ahead of Time?

Yes. You can prepare the potatoes and onions in advance. To prevent browning, keep sliced raw potatoes submerged in cold water in the refrigerator, then drain and dry thoroughly before cooking.

7. Can I Freeze Slow Cooker Potatoes and Onions?

Freezing is possible, but the potatoes may become watery or grainy after thawing. Refrigeration is recommended for the best texture.

8. What Can I Serve With Slow Cooker Potatoes and Onions?

These potatoes pair beautifully with roasted chicken, pork chops, grilled steak, meatloaf, baked fish, or a fresh green salad.

9. Why Are My Potatoes Mushy?

The potatoes may have been sliced too thinly, cooked too long, or stirred too frequently. Use thicker slices and check for doneness before the maximum cooking time.
