Ingredients for Scalloped Potatoes with Mushroom Soup
Here’s what you’ll need to bring this simple, soulful dish to life:
- 4 medium russet potatoes

How to Make Scalloped Potatoes with Cream of Mushroom Soup: A Step-by-Step Guide
Let’s embark on this simple culinary journey together. Here’s how to create this comforting dish, step by gentle step:
- Preheat & Prep: Start by preheating your oven to 350 degrees Fahrenheit.
- Slice the Potatoes: Thinly slice each potato. Using a slicing tool makes this easier and more consistent. I cherish my Mom’s rotary slicing tool with a hand crank. If you don’t have one, a mandoline or food processor with a slicing attachment works well too.
- Combine Potatoes and Onions: In a large bowl, stir together the sliced potatoes and diced onions.
- Make the Creamy Sauce: In a separate bowl, whisk together the cream of mushroom soup and milk until well combined. Season with salt and pepper to taste. Pour the mushroom soup sauce over the potatoes and onions.
- Assemble the Casserole: Transfer the mixture into a 2-liter (or 2-quart) casserole dish.
- Cheese and Bake: Top with 1 cup of the grated cheddar cheese. Cover with a lid or aluminum foil and bake for 60-80 minutes, or until the potatoes are tender.
- Broil for Golden Perfection: Remove the lid, add the remaining 1/2 cup grated cheese, and place on the top rack. Turn the broiler on and cook for about 5 minutes, or until the cheese is melted and lightly browned.
- Rest and Serve: Let the scalloped potatoes rest for a few minutes before serving. This allows the sauce to thicken slightly and the flavors to meld together beautifully.
Pro Tips for the Perfect Scalloped Potatoes
A few simple tips can elevate this dish from good to unforgettable:
- Even Slicing is Key: Ensure the potatoes are sliced evenly for uniform cooking. This helps everything cook at the same rate.
- Don’t Overcrowd the Pan: Use a large enough casserole dish to prevent overcrowding, which can lead to uneven cooking.
- Season Generously: Taste and adjust the seasoning of the sauce before baking. Salt and pepper are your friends!
- Patience is a Virtue: Resist the urge to crank up the heat. Low and slow baking ensures the potatoes are fully cooked and the sauce is creamy.
Common Mistakes to Avoid
Even simple recipes can have pitfalls. Here’s what to watch out for:
- Undercooked Potatoes: This is the biggest risk! Make sure the potatoes are tender before adding the final layer of cheese.
- Dry Sauce: If the sauce seems too thick, add a splash more milk.
- Burnt Cheese: Keep a close eye on the cheese while broiling to prevent it from burning.
- Bland Flavor: Don’t be afraid to experiment with seasonings. Garlic powder, onion powder, or a pinch of nutmeg can add depth.
Variations to Make It Your Own
This recipe is a blank canvas, ready for your personal touch:
- Add Some Protein: Stir in cooked ham, bacon, or sausage for a heartier meal.
- Spice It Up: Add a pinch of red pepper flakes or a dash of hot sauce for a little kick.
- Vegetable Boost: Mix in other vegetables like sliced mushrooms, bell peppers, or spinach.
- Cheese Swap: Experiment with different cheeses like Gruyere, Monterey Jack, or a blend of your favorites.
- Herb Infusion: Add fresh herbs like thyme, rosemary, or parsley for a fragrant twist.
How to Store and Reheat Scalloped Potatoes
Leftovers are a treasure! Here’s how to store and reheat them properly:
- Storage: Let the scalloped potatoes cool completely, then cover tightly with plastic wrap or transfer to an airtight container. Store in the refrigerator for up to 3-4 days.
- Reheating: Reheat in the oven at 350 degrees Fahrenheit until warmed through, or microwave individual portions. Add a splash of milk if the sauce seems dry.
Frequently Asked Questions (FAQ)
Let’s address some common questions about making scalloped potatoes:
- Can I use a different type of potato?: Yes, Yukon Gold or red potatoes work well. They have a creamier texture.
- Can I make this ahead of time?: Yes, you can assemble the casserole a day in advance and store it in the refrigerator. Add the cheese just before baking.
- Can I freeze scalloped potatoes?: While you can freeze them, the texture may change slightly upon thawing. The potatoes might become a bit mushy.
- How do I know if the potatoes are fully cooked?: To determine if the potatoes are fully cooked, poke them with a fork. If the fork slides in easily, the potatoes are done. The sauce should be bubbling around the edges and the potatoes should be tender when poked with a fork.
