Scalloped Potatoes Recipe Details
I love how these scalloped potatoes, especially with mushrooms. They add a meatiness without there actually being any meat!
- TASTE: These Scalloped Potatoes are cheesy and rich, with an earthy flavor from the mushrooms that pairs nicely with the slight sweetness of the tender onions.
- TEXTURE: Bubbling melted cheese and cream are in between layers of tender mushrooms, potato, and onion for a delicious side that will have everyone asking for seconds.
- TIME: This dish will take about 90 minutes from start to finish.
- EASE: Simple and easy to follow, this recipe makes it a snap to put out perfect scalloped potatoes every time.
What You’ll Need
- Vegetables- Cremini mushrooms (sliced), Golden Yukon potatoes, Yellow onion, and Green onion
- Seasonings- Salt, Black pepper, Garlic powder
- Creamy base- Unsalted butter, Parnesan cheese (grated), Half & Half, and Mozzarella cheese (shredded)
How to Make Scalloped Potatoes
- Saute the mushrooms. In a large skillet, sauté the sliced mushrooms until they become tender.
- Cut the potatoes. Using a sharp knife or mandolin, thinly slice the Yukon potatoes and place them into a bowl. Season with salt, black pepper, and garlic powder.
Pro Tip: If you have one, use a mandolin for slicing the potatoes. Once you get the hang of this gadget, it is much faster and more precise than using a knife.
- Add the onion and potatoes to the baking dishes. Generously grease 2 baking dishes or oval gratins with the unsalted butter. First layer the sliced yellow onion, then the potatoes in each dish.
- Add the rest of the ingredients. Now top the potatoes with sliced green onion. Then add the Parmesan and shredded mozzarella cheeses. Layer the rest of the potatoes on top and add the remaining cheeses. Finally, pour the Half & Half right on top.
- Bake. Cover the baking dishes with aluminum foil and bake at 400 degrees Fahrenheit for about 30 minutes. Then remove the foil and bake for an additional 30 minutes.
Recipe Tips
- Thinly slice the potatoes- Scalloped potatoes need thin potatoes in order to layer with cheese and milk and other vegetables. Use a mandolin for even slicing to give your dish the perfect texture.
- Saute the mushrooms for better flavor- Cooking the mushrooms brings out a natural sweetness and delicious earthy flavor. This step makes them taste even better and also tenderizes them.
- Layer your dish- Layering the ingredients rather than just adding them all together gives this side dish it’s traditional appearance, but also gives each bite a little bit of every flavor.
- Bake without foil in the end– Taking off the foil allows the cheeses on top to get direct heat so they brown and crisp a little, adding a yummy layer of bubbling cheesiness.
Add-ins and Substitutions
- Skip the mushrooms- If you’re not a fan, you can skip this ingredient. I love the meatiness it adds to this vegetarian dish, but you can easily make this recipe without it. Or use a variety that you prefer.
- Make it lighter- To make a lighter version of these Scalloped Potatoes, substitute a fat-free Half & Half and use part-skim mozzarella cheese when you make them.
- Use other potatoes- I love the traditional Yukon potatoes, but you can use most potato varieties in this recipe, including Russet and red potatoes, or even sweet potatoes.
- Make it vegan/dairy-free- If you want to serve these dairy-free, then substitute the Half & Half, cheeses, and butter for vegan/plant-based versions. They’re easy to find in grocery and health stores.
FAQs
The most commonly used potatoes are Yukon gold potatoes. You can use russet potatoes, red potatoes, or even sweet potatoes, but I prefer the traditional version.
The best and easiest way to thinly slice potatoes is by using a mandolin. If you do not have a mandolin, you can always use the blade attachment on your food processor. And if all else fails, a really sharp knife is your next resort. If your knife is dull and you don’t know how to sharpen a knife, this knife sharpener is my best friend when it comes to that.
Serving Suggestions
This Scalloped Potatoes recipe can easily go with any dish you want to serve it with. Here are a few delicious ways to serve this side dish.

- Seafood: Pesto Salmon (VIDEO), Easy Baked Cod (cod en papillote), and Blackened Cajun Shrimp make a delicious main course with this side.
- Salad: Serve these rich potatoes with a light salad, such as this Cabbage Cucumber Salad, Spinach Pomegranate Salad, or Best Broccoli Cranberry Salad.

Make This Scalloped Potatoes Recipe in Advance
Make ahead: Just bake the Scalloped Potatoes as you normally would, and once they have cooled, tightly cover them with foil. Refrigerate for up to 3 days, then bake (covered) for about 30 minutes at 360 degrees Fahrenheit, or until fully warmed through.
Storing: These potatoes will last in the refrigerator in an airtight container for up to 3 days.
Freeze: Unfortunately, scalloped potatoes don’t freeze too well. So I wouldn’t recommend freezing them.

Tatyana says
I love scalloped potatoes but no matter how many times I tried making it, potatoes were never able to cook through and always stayed crunchy and not soft. I used the slicer and they were super thin, what could be the reason. I know it’s not time cuz one time I cooked it for two hours and nothing changed.
Dina says
Hi Tatyana, that is so odd. Do you cover the potatoes with foil? The foil helps create a steamy setting so the potatoes get soft and moist. I hope this helps.
Maria says
This is so delicious! My family is a fan of potatoes, this should be exciting to make! Thank you for sharing!

Yay! I hope you all enjoyed the scalloped potatoes Maria 🙂
Anna says
Hi there, I have a couple questions.
First, if I wanted to add chicken, would I add in raw chicken or partially cooked?
Second, if I’m planning to make a larger portion,
Would the time in the oven stay the same?
Thanks!
simplyhomecooked says
Hi Anna, great questions. You can add raw chicken slices, just make sure they aren’t very thick cuts. That way, if they’re thinner cuts, they will cook at the same time as the potatoes. If you plan to make a larger portion, cooking time will more likely be longer. I hope that helps 🙂
