Creamy, Homemade Comfort from Mom’s Kitchen

Growing up, my mother and I made scalloped potatoes often. Potatoes were inexpensive, and boxed mixes just weren’t in the grocery budget. So we learned to make them from scratch.
And honestly? Homemade was always better.
There’s something special about a bubbling casserole dish filled with tender potatoes layered in creamy white sauce. It’s simple food, but it fills you up and warms you through — especially when served alongside crispy oven-baked chicken or roasted meats.
The secret to truly good scalloped potatoes is the homemade white sauce. Once you learn how easy it is to make, you’ll never need a packet again.
You can keep this dish traditional, or turn it into a full meal by adding cooked ham, browned sausage, or seasoned ground beef between the layers.
Simple. Budget-friendly. Made with love.
Ingredients:
5 Tbs. butter
5 Tbs. flour
5 c. milk
(Or substitute 3 cups milk + 2 cups chicken broth for deeper flavor)
1 to 1 1/2 tsp. salt
1/2 to 1/2 tsp. pepper
6 c. potatoes, sliced about 1/2-inch thick
1 onion, thinly sliced into half rings
2 cloves garlic, minced
Directions:
Preheat oven to 350°F. One 3-quart baking dish with a lid.
In a large saucepan, melt butter over low heat. Stir in the flour and increase heat to medium. Cook and stir for 1 minute to form a smooth roux.
Gradually add the milk (or milk and broth mixture), stirring constantly to prevent lumps. Continue cooking and stirring for about 2 minutes, or until the sauce thickens.
Stir in the minced garlic and season with salt and pepper to taste.
In a 3-quart baking dish, layer one-fourth of the sliced potatoes and onions. Pour one-fourth of the sauce over the top. Repeat the layers three more times, finishing with sauce. Cover with a lid.
Place the baking dish on a baking sheet (to catch any bubbling sauce).
Bake for 60 to 70 minutes, or until the potatoes are tender and the top is lightly golden.
Let rest for 5–10 minutes before serving.
Makes 8 servings.
Tips & Extras:
• For evenly sliced potatoes, use a mandoline or a food processor with a slicing disc.
• Add shredded cheese between the layers for cheesy scalloped potatoes.
• Stir in cooked ham, sausage, or ground beef to make it a heartier main dish.
• If the top begins to brown too quickly, loosely cover with foil.
Tips for the Best Scalloped Potatoes:
• Slice potatoes evenly. Thin, uniform slices (about ⅛-inch thick) ensure they cook evenly. A mandoline makes this much easier.
• Don’t rush the sauce. Cook the butter and flour for a full minute before adding milk. This removes the raw flour taste and creates a smoother sauce.
• Warm the milk slightly before adding. Cold milk can sometimes cause lumps. Room temperature or slightly warmed milk blends more smoothly.
• Season every layer lightly. Potatoes need salt. A tiny pinch over each layer makes a big difference.
• Let it rest before serving. Resting 5–10 minutes allows the sauce to thicken and set properly.
🧂 Variations & Substitutions:
This is such a flexible comfort dish.
Cheesy Scalloped Potatoes
Add 1–2 cups shredded cheddar, Colby Jack, or Gruyère between layers.
With Ham or Sausage
Layer in 1–2 cups cooked diced ham, browned sausage, or ground beef to make it a full meal.
Garlic Lover’s Version
Increase garlic to 3–4 cloves for deeper flavor.
Use Broth for Richness
Replace 2 cups of milk with chicken broth for a more savory taste.
Make It Lighter
Use 2% milk instead of whole milk. The sauce will be slightly less rich but still creamy.
Add Fresh Herbs
Sprinkle chopped parsley or thyme between layers for a garden-fresh twist.

How to Store & Reheat:
To Store:
Allow scalloped potatoes to cool completely. Cover tightly or transfer to an airtight container. Refrigerate for up to 4 days.
To Freeze:
While best fresh, scalloped potatoes can be frozen. Cool completely, wrap tightly in plastic wrap and foil, and freeze up to 2 months.
To Reheat (Oven – Best Method):
Cover with foil and warm at 325°F until heated through (about 20–25 minutes).
To Reheat (Microwave):
Heat individual portions in 30-second intervals until warm.
If the sauce seems thick after storing, add a splash of milk before reheating.
Frequently Asked Questions:
Why are my scalloped potatoes still firm?
They may have been sliced too thick. Thin slices cook more evenly.
Can I make this ahead of time?
Yes. Assemble the dish, cover, and refrigerate up to 24 hours before baking. Add 10–15 extra minutes to the baking time.
What’s the difference between scalloped potatoes and au gratin?
Scalloped potatoes traditionally use a white sauce. Au gratin includes cheese in the sauce and often on top.
Can I use russet potatoes?
Yes! Russets create a softer texture. Yukon Gold potatoes hold their shape slightly better.
Can I double this recipe?
Absolutely. Use a larger baking dish and allow extra baking time as needed.
