Cream of Mushroom Scalloped Potatoes: A Comfort Food Classic

The memory is etched in my mind: Thanksgiving at Grandma’s. The aroma of roasting turkey mingled with the earthy scent of sage stuffing and, most importantly, the creamy, savory allure of scalloped potatoes. They weren’t just any scalloped potatoes, though. Grandma always added a secret ingredient – a can of cream of mushroom soup – that elevated the dish to a whole new level of comforting deliciousness. Every year, a silent battle raged for the corner piece, the one with the perfectly browned, slightly crispy edges. This Cream of Mushroom Scalloped Potatoes recipe is my attempt to recapture that magic, to bring a taste of Grandma’s love to your table.

Recipe Overview

• Prep Time: 30 minutes
• Cook Time: 1 hour 30 minutes to 1 hour 50 minutes
• Total Time: 2 hours to 2 hours 20 minutes
• Servings: 8-10
• Yield: 1 casserole
• Dietary Type: Not specified (can be adapted)

Ingredients

• 8 medium potatoes, peeled
• 1 medium onion, chopped
• 1 lb bacon
• 1 cup sour cream
• 1 can cream of mushroom soup
• Salt and pepper to taste
• 1 1/2 cups shredded cheddar cheese

Equipment Needed

• Large skillet
• Paper towels
• 13×9 inch casserole dish
• Knife
• Cutting board
• Aluminum foil
• Mixing bowl

Instructions

1. First, prepare the bacon. In a large skillet over medium heat, fry the bacon until it is crisp. Remove the bacon from the skillet and place it on paper towels to drain the excess grease. Once cooled, crumble the bacon.

2. Carefully discard all but 1 tablespoon of the bacon grease from the skillet. Add the chopped onion to the skillet and sauté over medium heat until softened and translucent. Be sure to stir occasionally to prevent burning. Remove the onions from the skillet and drain well on paper towels to remove the excess grease.

3. While the onion is sautéing, peel the potatoes and slice them thinly. A mandoline slicer can be helpful for achieving even slices, but a sharp knife works just as well. Aim for slices about 1/8 inch thick.

4. Preheat your oven to 350 degrees Fahrenheit (175 degrees Celsius). Butter a 13×9 inch casserole dish to prevent sticking.

5. Now it’s time to assemble the casserole. Layer the sliced potatoes in the prepared casserole dish. Next, add a layer of the crumbled bacon and a layer of the sautéed onion mixture. Repeat these layers, finishing with a layer of potatoes on top. Season each layer with salt and pepper to taste.

6. In a mixing bowl, combine the sour cream, shredded cheddar cheese, and cream of mushroom soup. Mix well until all ingredients are thoroughly combined.

7. Carefully pour the sour cream mixture evenly over the top of the layered potatoes in the casserole dish. Ensure that the potatoes are mostly covered by the creamy sauce.

8. Cover the casserole dish tightly with aluminum foil. Bake in the preheated oven for 1 hour to 1 hour and 30 minutes.

9. After the initial baking time, carefully remove the aluminum foil. Bake for an additional 20 minutes, or until the potatoes are tender and the top is golden brown and bubbly. A fork should easily pierce the potatoes when they are done.

10. Remove the casserole from the oven and let it rest for about 10-15 minutes before serving. This allows the sauce to thicken slightly and prevents it from being too runny.

Expert Tips & Tricks

• Even Slicing is Key: Consistent potato slice thickness ensures even cooking. If you don’t have a mandoline, take your time and aim for uniform slices.
• Don’t Overcook the Onions: Sauté the onions until they are just softened. Overcooked onions can become bitter.
• Adjust Baking Time: Oven temperatures can vary, so check for doneness after 1 hour and 15 minutes. The potatoes are done when they are easily pierced with a fork. If the top is browning too quickly, cover it loosely with foil.
• Make-Ahead Magic: Assemble the casserole a day in advance and store it in the refrigerator. Add about 15-20 minutes to the baking time to ensure it’s heated through.
• Crispy Bacon Perfection: For extra crispy bacon, consider baking it in the oven instead of frying it on the stovetop.

Serving & Storage Suggestions

Serve the Cream of Mushroom Scalloped Potatoes hot, straight from the oven. Garnish with a sprinkle of fresh chopped parsley or chives for a pop of color and fresh flavor. This dish is a wonderful side dish for roasted chicken, ham, or beef.

Leftovers can be stored in an airtight container in the refrigerator for up to 3-4 days. To reheat, bake in a preheated oven at 350 degrees Fahrenheit until warmed through, or microwave in individual portions. Be aware that the texture may change slightly upon reheating; the sauce may become a bit thinner. While freezing is possible, the texture of the potatoes and sauce may be affected.
