Mom’s Scalloped Potatoes: A Taste of Home

The scent of baking potatoes, creamy sauce bubbling gently at the edges of the casserole dish… that’s pure, unadulterated comfort. I can still picture my mom, apron tied tight, carefully layering thinly sliced potatoes in her trusty Pyrex dish. It wasn’t a fancy meal, but it was made with love and always disappeared in minutes. These scalloped potatoes aren’t just food; they’re a warm hug on a plate, a taste of childhood that I cherish.

Recipe Overview

• Prep Time: 20 minutes
• Cook Time: 1 hour 30 minutes
• Total Time: 1 hour 50 minutes
• Servings: 6
• Yield: One 2-quart casserole dish
• Dietary Type: Vegetarian (Can be made gluten-free by using gluten-free flour)

Ingredients

• 2 lbs potatoes, peeled
• 3 tablespoons butter
• 3 tablespoons flour
• 2 ½ cups milk
• ¼ cup onion, finely chopped

Equipment Needed

• Medium saucepan
• Whisk
• 2-quart casserole dish
• Sharp knife or mandoline

Instructions

1. Preheat your oven to 350 degrees F (175 degrees C).

2. Begin by preparing the potatoes. Peel them and thinly slice them using a sharp knife or a mandoline. The thinner the slices, the more evenly they will cook. Immediately after slicing, place the potatoes in a bowl and cover them with cold water. This prevents them from browning and helps remove excess starch. Set aside.

3. In a medium saucepan, melt the butter over medium heat. Make sure the butter doesn’t brown.

4. Once the butter is melted, add the flour. Stir constantly with a whisk until no lumps remain. This creates a roux, which will thicken the sauce.

5. Gradually add the milk to the roux, whisking continuously to prevent lumps from forming.

6. Cook the milk and flour mixture over medium heat, stirring frequently, until it thickens enough to coat the back of a spoon. This usually takes about 5-7 minutes. The sauce should be smooth and creamy.

7. While the sauce is thickening, grease a 2-quart casserole dish with butter or cooking spray.

8. Now, it’s time to assemble the scalloped potatoes. Start by layering one-third of the sliced potatoes in the bottom of the greased casserole dish. Make sure to drain the potatoes before layering.

9. Sprinkle half of the finely chopped onion over the potato layer. The onion adds a subtle but important flavor to the dish.

10. Pour one-third of the white sauce over the potato and onion layer, ensuring that the potatoes are evenly coated.

11. Repeat the layers: another one-third of the sliced potatoes, the remaining half of the onion, and another one-third of the white sauce.

12. Finish with the remaining potatoes and top with the remaining white sauce.

13. Dot the top of the casserole with a few small pats of butter. This will add richness and help the top brown nicely.

14. Cover the casserole dish with a lid or aluminum foil.

15. Bake in the preheated oven for 30 minutes. This initial covered baking time helps the potatoes cook through evenly.

16. Remove the lid or foil and continue baking for an additional 1 hour, or until the potatoes are tender and the top is golden brown and bubbly. A knife or fork should easily pierce the potatoes when they are done.

17. Let the scalloped potatoes rest for about 10-15 minutes before serving. This allows the sauce to thicken slightly and makes it easier to serve.

Expert Tips & Tricks

• Potato Perfection: Choose Yukon Gold potatoes for their creamy texture or Russet potatoes for a more classic result. Regardless of the variety, consistent slicing is key. A mandoline slicer ensures uniform thickness, which guarantees even cooking.
• Sauce Consistency: Don’t rush the sauce-making process. A smooth, lump-free sauce is essential. If you do get lumps, try whisking vigorously or using an immersion blender to smooth it out. If the sauce is too thick, add a little extra milk until you reach the desired consistency.
• Browning Boost: For an extra golden-brown crust, sprinkle a little grated Parmesan cheese or bread crumbs over the top during the last 15 minutes of baking.
• Make-Ahead Magic: Scalloped potatoes can be assembled ahead of time and stored in the refrigerator for up to 24 hours before baking. Add a few minutes to the baking time if baking from cold.
• Preventing a Boilovers: If you notice the sauce bubbling over during baking, lower the oven temperature slightly or place a baking sheet underneath the casserole dish.

Serving & Storage Suggestions

Serve Mom’s Scalloped Potatoes hot as a comforting side dish with roasted chicken, ham, or your favorite protein. They are also delicious on their own as a vegetarian main course.

To store leftovers, allow the scalloped potatoes to cool completely before transferring them to an airtight container. They can be stored in the refrigerator for up to 3-4 days.

To reheat, bake in a preheated oven at 350 degrees F (175 degrees C) until heated through, or microwave in individual portions. You may need to add a splash of milk to the sauce if it has thickened too much during storage. Scalloped potatoes are not ideal for freezing as the potatoes can become mushy.
