Homemade Scalloped potatoes with creamy alfredo sauce and mushrooms. This cheesy scalloped potatoes recipe is easy and loaded with lots of umami flavor and garlic! You will love these scalloped potatoes from scratch!
Boil the potatoes in 2 cups of water until fork-tender (about 15 minutes.) Remove and cool on a plate. Set aside.
In a large skillet over medium-high heat, melt the butter and olive oil. Saute the mushrooms and onion until soft (about 10 minutes.) Add the garlic and cook for 1 more minute.
Add the seasonings and soup mix.
Stir in the heavy cream and parmesan cheese and bring to a boil. Simmer for 2 minutes, uncovered.
Peel the skins off the potatoes and slice them into 1/2-inch slices. Assemble into a 9x13 baking dish.
Pour 4-5 cups of the mushroom alfredo sauce over the potatoes and sprinkle with mozzarella cheese.
Bake covered at 400°F for 30 minutes. Then uncover and broil for 5 minutes to make a browned cheese crust.
Notes
**Mushroom Alfredo Sauce makes about 6.5 cups of sauce, this is enough for 2 casseroles, or reserve the other half for another alfredo dish.
You can freeze this scalloped potato recipe after assembling it or make it ahead and store it in the fridge for up to 5 days.
