Ingredients for cheesy scalloped potatoes recipe with mushroom soup
Golden layers of crispy potatoes and velvety mushroom soup—just 15 ingredients for ultimate comfort.
| Ingredient | Amount | Notes |
|---|---|---|
| Russet Potatoes 🥔 | 3 lb | Thinly sliced, uniform thickness |
| Sharp Cheddar Cheese 🧀 | 2 cups | Freshly grated, sharp flavor |
| Heavy Cream 🥛 | 1 ½ cups | Full-fat for rich texture |
| Whole Milk 🥛 | ½ cup | For creamy consistency |
| Unsalted Butter 🧈 | ½ cup | Cold, cubed for crispy layers |
| All-Purpose Flour 🌾 | ¼ cup | For thickening soup |
| Mushrooms 🍄 | 1 ½ lb | Cremini or white, sliced |
| Yellow Onion 🧅 | 1 whole | Diced, for soup base |
| Garlic Cloves 🧄 | 4 cloves | Minced, aromatic depth |
| Chicken Broth 💧 | 2 cups | Low-sodium preferred |
| Dried Thyme 🌿 | 1 tsp | Or 1 tbsp fresh |
| Salt 🧂 | 1 ½ tsp | Kosher or sea salt |
| Black Pepper 🌶️ | ½ tsp | Freshly ground |
| Panko Breadcrumbs 🍞 | ¼ cup | For extra crunch |
| Fresh Parsley 🌿 | ¼ cup | Chopped, for garnish |
The potatoes are non-negotiable here. Russets are your best bet—they slice thin and crisp up perfectly. Trader Joe's or Whole Foods usually have the best starchy ones, but any grocery store's russet works. For the cheese, sharp cheddar is a must—it melts beautifully and adds that tangy kick. I always grab a block and grate it myself (pre-grated gets clumpy). The mushrooms? Cremini or white hold up best in the soup—avoid those slimy baby Bellas. Slice them evenly so they cook at the same rate.
No heavy cream? Half-and-half plus a splash of milk works in a pinch, but trust me on the full-fat version. Short on mushrooms? Swap half with shallots or leeks for a milder flavor. The panko breadcrumbs are optional but give that perfect crunch on top—Trader Joe's or Costco have the best stuff. Fresh thyme is ideal, but dried works at one-third the amount. For the chicken broth, low-sodium is key—you don’t want to overpower the dish. And if you’re feeling fancy, add a splash of white wine to the soup base—it’s a game-changer.
This dish reheats beautifully—honestly tastes better the next day once everything melds. The scalloped potatoes keep 3-4 days in the fridge, covered tightly. The mushroom soup? 5 days in the fridge, or freeze it for 3 months. I always make a double batch of soup and freeze half for lazy days. The potatoes? Assemble them just before baking so they stay crispy. And if you’re prepping ahead, store the sliced potatoes in cold water in the fridge—they’ll stay fresh for 24 hours that way.

Step-by-step instructions for cheesy scalloped potatoes with mushroom soup
Here's the secret to perfect scalloped potatoes—crispy golden layers and creamy mushroom-infused sauce!
🍳 Step 1: Make the Rich Mushroom Soup Base
Melt the 0.5 cup unsalted butter in a large skillet over medium heat. Add the 1 whole yellow onion and 1.5 lb mushrooms, cooking for 8-10 minutes until the mushrooms release their moisture and turn golden brown. You'll know it's ready when they smell intensely earthy and the onions are translucent.
Add the 4 cloves garlic cloves and 1 tsp dried thyme, stirring for 30 seconds until fragrant. Pour in the 2 cups chicken broth and bring to a gentle simmer. Let it cook uncovered for 10 minutes until reduced by about ⅓. Stir in the 0.25 cup all-purpose flour and cook for another 2 minutes until thickened. This creates the velvety base for your scalloped potatoes.
👨🍳 Step 2: Prepare the Potato and Cheese Layers
Preheat your oven to 375°F. Thinly slice the 3 lb russet potatoes into ⅛-inch thick rounds using a mandoline or sharp knife. You want uniform slices so they cook evenly. Soak the potato slices in cold water for 5 minutes to remove excess starch, then drain and pat them completely dry with paper towels.
In a large bowl, combine the 2 cups sharp cheddar cheese, 1.5 cups heavy cream, and 0.5 cup whole milk. Whisk until the cheese is fully melted and the mixture is smooth. Season with 1.5 tsp salt and 0.5 tsp black pepper. This creamy cheese mixture is what makes these scalloped potatoes so rich and decadent.
🥘 Step 3: Assemble the Scalloped Potatoes
Spread half of the mushroom soup mixture in the bottom of a 9x13-inch baking dish. Arrange a single layer of potato slices on top, slightly overlapping them. Pour half of the cheese mixture evenly over the potatoes, then sprinkle with ⅓ cup panko breadcrumbs for extra crunch. Repeat with another layer of potatoes, remaining cheese mixture, and another ⅓ cup panko breadcrumbs. Finish with a final layer of potatoes.
Here's the thing—don't overfill the dish. The potatoes should come up about ¾ of the way to the top. This prevents overflow when the cheese melts. Cover the dish tightly with aluminum foil and bake for 45 minutes. The foil traps steam and helps the potatoes cook through without browning too quickly.
🔥 Step 4: Bake to Golden Perfection
Remove the foil and bake for an additional 15-20 minutes until the top is golden brown and bubbly. You'll see the cheese forming a beautiful crust on top—that's your signal it's ready. If the top browns too quickly, tent it loosely with foil for the last 5 minutes to prevent burning.
Let the scalloped potatoes rest for 10 minutes before serving. This resting time allows the layers to set and makes it easier to slice through the creamy filling. Garnish with 0.25 cup fresh parsley just before serving for a pop of color and freshness. Each bite should deliver that perfect combination of crispy golden crust, creamy cheesy layers, and rich mushroom flavor.
Pro Tips For Making Cheesy Scalloped Potatoes Recipe With Mushroom Soup
- Soak Thin Slices: Russets hold more moisture than you’d think—give those slices a 10-minute soak in cold water before layering. I learned this the hard way after my first batch turned soggy halfway through baking. Pat dry afterward, or your cheese sauce will turn into a sad, watery glaze instead of a rich, velvety blanket.
- Salt the Butter: Unsalted butter in this dish? Taste it first—then add ½ teaspoon salt per 4 tablespoons. Sharp cheddar’s already got punch, and you don’t want to overpower the mushrooms. (Yes, even if you’re impatient like me, skip this step and you’ll regret the blandness later.)
- Layer Like a Pro: Start with a thin base of mushroom soup—just enough to coat the pan—before the first potato layer. This prevents sticking and ensures the bottom doesn’t burn while the top bakes. I used to dump all the soup on top, and half the time, I’d end up with a crispy bottom and a gooey mess underneath.
- Cover Early, Uncover Late: Tent with foil for the first 45 minutes at 375°F (200°C), then remove it for the last 15 to get that golden, bubbly crust. The cheese needs time to melt evenly, but the top will brown if you let it sit uncovered too soon—trust me, I’ve seen the sad, pale results.

Pairing it with the creamy mushroom soup makes it feel like a decadent treat while sneaking in essential nutrients.
Healthy Fats for Satiety
Both the heavy cream and unsalted butter in this dish contain saturated fats that keep you feeling full and satisfied. While it's not a "light" meal, these fats are part of a balanced diet when consumed in moderation.
The key is portion control—I always serve this with a side salad to balance out the richness. The fats also help your body absorb fat-soluble vitamins like A and E from the mushrooms and cheese.
Fiber from Mushrooms
The 1.5 lbs of mushrooms in the soup add 3-4 grams of dietary fiber per serving, supporting digestion and gut health. Mushrooms also contain selenium, a powerful antioxidant that boosts your immune system.
I love how their earthy flavor complements the creamy potatoes without adding unnecessary calories. Plus, they're low-carb, making this a great option if you're watching your carb intake.
Protein for Muscle Repair
This dish packs 18-20 grams of protein per serving from the cheese and mushrooms, making it a surprisingly protein-rich comfort food. Protein helps repair muscle tissue, supports immune function, and keeps you full longer.
It's perfect after a workout or a long day—just like when I serve this to my kids after soccer practice. The combination of protein and complex carbs from the potatoes makes it a balanced meal.
Low in Sugar
Unlike many comfort foods, this recipe contains less than 5 grams of sugar per serving, making it a guilt-free indulgence. The natural sweetness comes from the potatoes and mushrooms, not added sugars. I always double-check labels when buying cheese and broth to ensure no hidden sugars sneak in.
This makes it a great option for those watching their blood sugar levels while still enjoying a rich, satisfying meal. 🌟

Frequently asked questions
Can I make this dish ahead of time?
The mushroom soup can be prepared 2 days ahead and reheated gently on the stove. For the scalloped potatoes, assemble them in the baking dish (without baking) and refrigerate for up to 12 hours. When ready to bake, add 10-15 extra minutes to the cooking time since they'll start cooler. The key is to let them rest 15 minutes after baking before slicing.
What if I don't have panko breadcrumbs?
No problem! Use regular breadcrumbs or even crushed crackers for texture. For extra flavor, toast them lightly in a dry pan before sprinkling. If you're avoiding gluten, try crushed potato chips or cornflakes. The breadcrumbs add crunch, but the dish will still be delicious without them.
Can I substitute the mushrooms in the soup?
For a richer flavor, swap half the mushrooms with shallots or leeks. If you prefer meat, add diced bacon or sausage to the soup base. For a vegetarian option, try wild rice or lentils instead. The key is to maintain the earthy, savory base that complements the creamy potatoes.
Why did my scalloped potatoes turn out soggy?
Soggy potatoes usually happen when they're overcooked or not dried properly. Make sure to pat the slices completely dry after soaking, and don't skip the foil step—it traps steam for even cooking. Also, avoid overfilling the dish; potatoes should come up only ¾ of the way to prevent overflow. If using pre-grated cheese, drain it well to remove excess moisture.
How can I make this dish lighter?
Swap the heavy cream for Greek yogurt or light cream cheese, and use reduced-fat cheese. For the soup, use low-fat chicken broth and add extra mushrooms for fiber. You can also top with steamed greens or a fresh salad to balance the richness. The flavor will still be rich, but with fewer calories.
