Cheesy Scalloped Potatoes Recipe
Introduction
Cheesy scalloped potatoes are a comforting classic with tender layers of thinly sliced russet potatoes baked in a creamy garlic sauce, topped with crispy bacon and sharp cheddar. This dish makes a perfect side for family dinners or holiday gatherings.

Ingredients
- 2 slices bacon, chopped into 1″ pieces
- 2 tbsp. light butter
- 2 garlic cloves, minced
- 3 tbsp. all-purpose flour
- 3 cups low-fat milk (1%)
- 1 lb. russet potatoes, rinsed, peeled, and thinly sliced
- 1 cup low-fat shredded cheddar cheese
- ¼ cup finely chopped chives or scallions
- Kosher salt, to taste
- Freshly ground black pepper, to taste
Instructions
- Step 1: Preheat the oven to 400°F (200°C). In a large skillet over medium heat, cook the bacon pieces until crispy, about 8 minutes. Remove and drain on paper towels.
- Step 2: In another large skillet over medium heat, melt the butter. Add the minced garlic and cook until fragrant, about 1 minute. Stir in the flour and cook for another minute, stirring constantly.
- Step 3: Gradually whisk in the milk, seasoning with salt and pepper. Simmer the sauce until slightly thickened, about 5 minutes, then remove from heat.
- Step 4: Peel the potatoes and slice them thinly into coins using a knife or mandolin for even slices.
- Step 5: Spoon a thin layer of the sauce into the bottom of a large casserole dish. Add a single layer of potato slices over the sauce.
- Step 6: Spoon more sauce over the potatoes, then sprinkle with cheddar cheese and crispy bacon pieces. Repeat layering potatoes, sauce, cheese, and bacon 3 to 4 times or until the dish is mostly full.
- Step 7: Bake in the preheated oven until the sauce is bubbly and the potatoes are very tender, about 1 hour and 15 minutes.
- Step 8: Let the scalloped potatoes rest for at least 15 minutes before serving. Garnish with chopped chives or scallions.
Tips & Variations
- Use a mandolin to slice the potatoes evenly and thinly for consistent cooking.
- Substitute crispy cooked pancetta or ham for bacon for a different smoky flavor.
- Add a pinch of nutmeg or smoked paprika to the sauce for added depth.
- For a richer dish, use whole milk or half-and-half instead of low-fat milk.
- Mix in some grated Parmesan cheese with the cheddar for an extra cheesy finish.
Storage
Store leftover scalloped potatoes in an airtight container in the refrigerator for up to 3 days. Reheat gently in the oven at 350°F (175°C) until warmed through, or microwave in short intervals stirring occasionally to prevent drying out.

FAQs
Can I prepare scalloped potatoes ahead of time?
Yes, you can assemble the dish a few hours in advance and keep it covered in the refrigerator. Bake it fresh when ready to serve for the best texture.

Ingredients
Main Ingredients
- 2 slices bacon, chopped into 1” pieces
- 2 tbsp light butter
- 2 garlic cloves, minced
- 3 tbsp all-purpose flour
- 3 cups low-fat milk (1%)
- 1 lb russet potatoes, rinsed and scrubbed clean
- 1 cup low-fat shredded cheddar cheese
- ¼ cup finely chopped chives or scallions
- Kosher salt, to taste
- Freshly ground black pepper, to taste
Instructions
- Cook Bacon: Preheat your oven to 400°F. In a large skillet over medium heat, cook the chopped bacon pieces until crispy, about 8 minutes. Remove the bacon and drain on paper towels to absorb excess grease.
- Prepare Cheese Sauce: In another large skillet over medium heat, melt the light butter. Add the minced garlic and cook until fragrant, about 1 minute. Stir in the all-purpose flour and cook for another minute to form a roux. Gradually whisk in the low-fat milk and season with kosher salt and freshly ground black pepper. Simmer the sauce for about 5 minutes until it thickens slightly, then remove from heat.
- Slice Potatoes: Peel the russet potatoes and slice them thinly into coins about 1/8 inch thick, using a mandolin slicer if available for uniform slices.
- Assemble Casserole: Spoon a thin layer of the prepared cheese sauce into the bottom of a large casserole dish. Layer a single layer of potato slices on top of the sauce. Spoon more sauce over the potatoes, then sprinkle a layer of shredded cheddar and some of the crispy bacon pieces. Repeat layering potatoes, sauce, cheese, and bacon 3 to 4 times, filling the casserole dish mostly full.
- Bake: Place the casserole dish in the preheated oven and bake for about 1 hour and 15 minutes, until the sauce is bubbly and the potatoes are very tender when pierced with a fork.
- Rest and Garnish: Allow the scalloped potatoes to rest for at least 15 minutes after baking to set the layers. Before serving, sprinkle the chopped chives or scallions on top for a fresh finish.
Notes
- Using a mandolin slicer helps achieve evenly thin potato slices which cook uniformly.
- Letting the dish rest after baking helps the sauce thicken and the casserole to hold its shape better when served.
- You can substitute bacon with pancetta or omit it for a vegetarian version (adjusting seasoning accordingly).
- This recipe makes approximately 6 servings, perfect as a side dish for holiday dinners or weeknight meals.
