The Simple Ingredients
Look at this list! Nothing weird. No trips to a special store. This is all about using simple things to make something amazing.
- 3 lbs Yukon Gold potatoes, thinly sliced (no peeling needed!)
- 1 tbsp olive oil
- 1 lb cremini or baby bella mushrooms, sliced
- 1 medium yellow onion, thinly sliced
- 3 cloves garlic, minced
- 1 (10.5 oz) can condensed cream of mushroom soup
- 1 1/2 cups vegetable broth
- 1 cup heavy cream or half-and-half
- 1 1/2 cups shredded Gruyère or sharp cheddar cheese, divided
- 1 tsp dried thyme
- 1/2 tsp smoked paprika
- Salt and black pepper to taste
- Fresh parsley for garnish (optional)
Let’s Get Cooking! (The Step-by-Step)
Ready? The steps are straightforward. I promise. Preheat your oven to 375°F (190°C). Grab a 9×13 inch baking dish. Let’s move.
- Prep the potatoes. Wash and thinly slice your potatoes. A mandoline makes this a 2-minute job. But a sharp knife works great too. Put the slices in a big bowl of cold water to prevent browning.
- Cook the mushrooms. Heat the olive oil in a large skillet over medium-high heat. Add the mushrooms and onion. Cook for 8-10 minutes until they’re golden brown and the liquid has evaporated. This builds deep flavor. Add the garlic and cook for 1 more minute.
- Make the magic sauce. In the same skillet, lower the heat. Pour in the cream of mushroom soup, vegetable broth, and heavy cream. Whisk it all together until smooth. Stir in 1 cup of the shredded cheese, the thyme, and smoked paprika. Season well with salt and pepper. Let it warm through until the cheese melts.
- Layer it up. Drain your potato slices. Pat them dry with a towel. Layer half the potatoes in your baking dish. Pour half the creamy mushroom sauce over them. Repeat with the remaining potatoes and sauce. Press the potatoes down gently so they’re covered.
- Top and bake. Sprinkle the remaining 1/2 cup of cheese over the top. Cover the dish tightly with foil. Bake for 30 minutes.
- Get it golden. Remove the foil. Bake for another 15-20 minutes until the top is beautifully golden and the potatoes are fork-tender.
- Rest and serve. Take the dish out of the oven. Let it sit for 10 minutes. This is key! It lets the sauce thicken up perfectly. Garnish with parsley if you like. Then, dig in!

Notes
Enjoy your homemade Creamy Mushroom Scalloped Potatoes Recipe!
Nutrition Information
A big, green salad with a tangy vinaigrette is perfect. It cuts through the richness. Some roasted asparagus or green beans are fantastic. For a protein boost, add a couple of fried eggs on top. Dinner is served in no time.
Make This Recipe Your Own (Quick Swaps)
Make this work for you. Use what you have. Here are my favorite easy swaps.
No cream of mushroom soup? Use cream of celery or golden mushroom soup. Out of fresh mushrooms? A 10-ounce bag of frozen sliced mushrooms works in a pinch. Thaw and squeeze them dry first. Want more greens? Stir a handful of fresh spinach into the sauce with the garlic.
How to Store Leftovers (If You Have Any!)
Leftovers are a gift! Let the dish cool completely. Store it in an airtight container in the fridge for up to 4 days.
Reheat single servings in the microwave. For a larger portion, cover it with foil and warm it in a 350°F oven until hot. The sauce might thicken in the fridge. A splash of broth or milk when reheating will smooth it right out.

FREQUENTLY ASKED QUESTIONS
Can I make this ahead of time?
Absolutely! Assemble the whole dish. Cover it and refrigerate for up to 24 hours. When you’re ready, bake it straight from the fridge. Just add 10-15 extra minutes to the covered baking time.
Can I use a different type of potato?
Yes. Russet potatoes work well. Just peel them first, as their skins can be tough. They might soak up a bit more sauce, so your bake will be slightly less creamy but just as delicious.
How do I get my potatoes to cook faster?
Slice them thin and even. This is the biggest trick. Thicker slices take much longer to soften. A mandoline slicer is a busy cook’s best friend for this job.
