Scalloped Potatoes Recipe

This scalloped potatoes recipe is loaded with bubbling cheese, fragrant onion, and sauteed mushrooms. The mushrooms are not necessary but I love how it adds more meatiness to the scalloped potatoes without actually adding meat.

These cheesy scalloped potatoes are a great idea for a vegetarian side dish. They can even be served as a meal on their own with a side salad. If you love vegetarian side dishes, you might want to try making sauteed asparagus, cheesy mushroom pinwheels, and, zucchini fritters.

How to make scalloped potatoes

• Thinly slice Yukon potatoes with a mandolin or sharp knife. Place the potato sliced into a bowl and season with salt, pepper, and garlic powder.
• Grease a baking dish or 2 oval gratins with unsalted butter, then add sliced onion into each dish.
• Then you’ll want to divide half the sliced potatoes between the two dishes. Now go ahead and add the sauteed mushrooms and sliced green onion on top. Next, you’ll want to sprinkle half of the parmesan cheese and half of the shredded mozzarella cheese on top.
• Place the remaining half of thinly sliced potatoes and add the rest of the parmesan and mozzarella cheese along with the half and half.
• Cover both baking dishes with foil and bake at 400 degrees Fahrenheit for approximately 30 minutes. Remove the foil and bake for an additional 30 minutes.

How to thinly slice potatoes

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.
