Ingredients For the Potatoes

• 2½ pounds Yukon Gold potatoes, washed and sliced into ¼-inch rounds

• 1 medium yellow onion, finely diced

• 2 tablespoons unsalted butter

• 2 garlic cloves, minced

For the Creamy Mushroom Sauce

• 1 can (10.5 ounces) condensed cream of mushroom soup

• 1 cup fresh mushrooms, finely sliced

• ½ cup sour cream

• ½ cup whole milk

• ½ cup low-sodium chicken broth

• ½ cup heavy cream

• 1 tablespoon all-purpose flour (optional, for thickening)

For the Seasonings

• 1 teaspoon garlic powder

• ½ teaspoon onion powder

• ½ teaspoon dried thyme

• ½ teaspoon freshly ground black pepper

• ¼ teaspoon smoked paprika

• ¼ teaspoon salt, or to taste

• 1 teaspoon Worcestershire sauce (optional)

Optional Cheesy Topping

• 1 cup shredded sharp cheddar cheese

• ¼ cup grated Parmesan cheese

• 2 tablespoons chopped fresh parsley

Step-by-Step Instructions

Step 1: Prepare the Potatoes

Wash the Yukon Gold potatoes thoroughly under cold running water.

Slice them into even rounds approximately ¼ inch thick. Keeping the slices uniform helps them cook evenly.

You can leave the skins on for extra texture or peel them for a smoother, more traditional casserole-style dish.

Lightly grease the inside of a 5–6 quart slow cooker with butter or nonstick cooking spray.

Step 2: Prepare the Mushrooms

Heat 1 tablespoon of butter in a skillet over medium heat.

Add the sliced mushrooms and cook for approximately 4–5 minutes until they release their moisture and begin to brown.

Stir in the diced onion and cook for another 3 minutes until softened.

Add the minced garlic and cook for 30 seconds until fragrant.

Remove the skillet from the heat.

Step 3: Make the Creamy Mushroom Sauce

In a medium mixing bowl, combine the condensed cream of mushroom soup, sour cream, whole milk, chicken broth, and heavy cream.

Whisk until smooth.

Add the garlic powder, onion powder, dried thyme, black pepper, smoked paprika, and Worcestershire sauce if using.

Stir in the sautéed mushroom, onion, and garlic mixture.

Taste the sauce and adjust the seasoning carefully, remembering that condensed soup already contains sodium.

Step 4: Layer the Potatoes

Arrange approximately one-third of the sliced potatoes evenly across the bottom of the prepared slow cooker.

Spoon one-third of the creamy mushroom sauce over the potatoes.

Repeat the layers until all the potatoes and sauce have been used.

Spread the remaining sauce evenly across the top to ensure the potatoes are well coated.

Step 5: Add the Butter

Cut the remaining tablespoon of butter into small pieces.

Scatter the butter evenly over the top of the potatoes.

This adds richness and helps create a smooth, buttery finish.

Step 6: Slow Cook Until Tender

Cover the slow cooker with its lid.

Cook on LOW for 4–5 hours or HIGH for 2½–3½ hours, until the potatoes are completely fork-tender.

Cooking times may vary depending on your slow cooker and the thickness of the potato slices.

Avoid opening the lid repeatedly because this releases heat and can extend the cooking time.

Step 7: Add the Cheese

If using the optional cheesy topping, sprinkle the shredded cheddar and grated Parmesan over the potatoes during the final 15–20 minutes of cooking.

Cover again and allow the cheese to melt completely.

For a creamier texture, gently stir a little of the melted cheese into the sauce without breaking the potato slices.

Step 8: Let the Potatoes Rest

Turn off the slow cooker.

Allow the potatoes to rest uncovered for approximately 10 minutes before serving.

The sauce will thicken slightly as it cools.

If the sauce appears too thick, stir in a small splash of warm milk.

Step 9: Garnish and Serve

Sprinkle freshly chopped parsley over the finished potatoes.

Add a little freshly ground black pepper or extra Parmesan if desired.

Serve warm directly from the slow cooker or transfer carefully to a serving dish.

Tips and Notes

1. Choose the Right Potatoes: Yukon Gold potatoes are ideal because they have a naturally buttery texture and hold their shape well during slow cooking.

2. Slice Evenly: Uniform potato slices ensure that every layer cooks at approximately the same rate.

3. Sauté the Mushrooms First: Browning fresh mushrooms develops deeper flavor and prevents excess moisture from watering down the sauce.

4. Don’t Overfill the Slow Cooker: Leave enough space for heat to circulate and the potatoes to cook evenly.

5. Use Freshly Shredded Cheese: Freshly grated cheddar melts more smoothly than many packaged shredded cheeses.

6. Avoid Excess Liquid: Potatoes and mushrooms release moisture as they cook, so additional broth may not be necessary.

7. Adjust the Creaminess: For a lighter sauce, replace the heavy cream with additional milk, although the finished dish will be less rich.

8. Add Protein: Cooked shredded chicken, diced ham, or browned sausage can turn this side dish into a hearty main meal.

9. Make It Vegetarian: Use vegetable broth and omit Worcestershire sauce unless it is specifically labeled vegetarian.

10. Store Leftovers Properly: Refrigerate leftovers in an airtight container within 2 hours of cooking. Enjoy within 3–4 days.

Frequently Asked Questions (Q&A)

Can I Use Russet Potatoes Instead of Yukon Gold?

Yes. Russet potatoes work well, but they contain more starch and may break apart more easily during slow cooking. Yukon Gold potatoes generally produce a creamier texture while maintaining their shape.

Can I Make This Recipe Without Cream of Mushroom Soup?

Absolutely! Replace the condensed soup with a homemade mushroom sauce made from sautéed mushrooms, butter, flour, milk, and broth. Cook the sauce until slightly thickened before layering it with the potatoes.

Can I Add Chicken to This Recipe?

Yes. Add fully cooked shredded chicken during the final 30 minutes, allowing it to heat thoroughly. This creates a filling creamy chicken and potato meal.

Why Are My Potatoes Still Firm?

The potato slices may be too thick, or your slow cooker may cook at a lower temperature. Continue cooking until the potatoes are easily pierced with a fork.

Can I Prepare This Recipe Ahead of Time?

Yes. Prepare the mushroom sauce a day ahead and refrigerate it. Slice the potatoes shortly before cooking to minimize discoloration.

Can I Freeze Creamy Mushroom Potatoes?

Freezing is possible, but potatoes may become grainy and dairy-based sauces can separate after thawing. For the best texture, refrigerate and enjoy within a few days.

How Can I Make the Sauce Thicker?

If the sauce is thin near the end of cooking, mix 1 tablespoon cornstarch with 1 tablespoon cold water. Gently stir it into the hot sauce around the potatoes and cook on HIGH for another 10–15 minutes until thickened.

What Can I Serve with Creamy Mushroom Potatoes?

These potatoes pair wonderfully with roasted chicken, grilled steak, baked ham, pork chops, meatloaf, or steamed vegetables.

Serving Suggestions

Slow Cooker Creamy Mushroom Potatoes are perfect for serving alongside classic comfort-food dinners.
