Buttermilk Scalloped Potatoes: A Comfort Food Classic

I remember my grandmother always making scalloped potatoes for Sunday dinners. The creamy, tangy aroma would fill the entire house, a promise of comfort and togetherness. Her version, though, was always incredibly rich and heavy, using cream and mountains of cheese. While delicious, it was a dish best enjoyed sparingly. This recipe captures the essence of those cherished memories but with a lighter, brighter twist thanks to the magic of buttermilk. It’s a side dish that’s both comforting and surprisingly refreshing.

Recipe Overview

• Prep Time: 20 minutes
• Cook Time: 60 minutes
• Total Time: 1 hour 20 minutes
• Servings: 4
• Yield: 1 casserole dish
• Dietary Type: Vegetarian

Ingredients

• 2 large baking potatoes, peeled and sliced thin
• 1/4 cup all-purpose flour
• 1 teaspoon salt
• 1/8 teaspoon paprika
• 1 medium onion, peeled and chopped
• 2 tablespoons unsalted butter
• 2 cups low-fat buttermilk

Equipment Needed

• 2-quart casserole dish
• Large zip-type plastic bag
• Medium saucepan
• Knife
• Cutting board
• Measuring cups and spoons

Instructions

1. Preheat your oven to 350°F (175°C).
2. Lightly coat the inside of a 2-quart casserole dish with nonfat cooking spray to prevent sticking. This will ensure easy serving and cleanup.
3. In a large zip-type plastic bag, combine the flour, salt, pepper (if desired – the original recipe does not list pepper but I added some for depth of flavour) and paprika. Seal the bag tightly.
4. Add the thinly sliced potato slices to the bag. Reseal the bag, making sure it’s secure, and shake vigorously until all the potato slices are evenly coated with the flour mixture. This ensures a creamy sauce without needing to make a separate roux.
5. Layer the coated potato slices evenly in the prepared casserole dish. Aim for overlapping layers to ensure even cooking and a beautiful presentation.
6. In a medium saucepan over medium heat, melt the butter. Add the chopped onion and saute until softened and translucent, about 5 minutes. Stir frequently to prevent browning. Softening the onions before baking helps mellow their flavor and infuses the buttermilk with a subtle sweetness.
7. Reduce the heat to low. Gradually add the buttermilk to the saucepan with the softened onions, stirring constantly. Heat the mixture gently; DO NOT BOIL! Boiling the buttermilk will cause it to curdle, resulting in an undesirable texture. The goal is to warm it through.
8. Carefully pour the warm buttermilk mixture evenly over the layered potatoes in the casserole dish. Ensure that the liquid reaches all the layers of potatoes.
9. Bake the scalloped potatoes, uncovered, for 1 hour or until the potatoes are tender and easily pierced with a fork. The top should be lightly golden brown. If the top starts to brown too quickly, you can loosely cover the dish with foil for the last 15-20 minutes of baking.

Expert Tips & Tricks

• Thin Potato Slices are Key: Uniformly thin slices of potato (about 1/8 inch thick) are crucial for even cooking. A mandoline slicer can be helpful for achieving consistent thickness.
• Don’t Overcrowd the Pan: Layering the potatoes too densely can prevent them from cooking evenly. Make sure there’s some space between the layers for the buttermilk to circulate.
• Cheese It Up (Optional): While this recipe omits cheese, a sprinkle of grated Gruyere or Parmesan during the last 15 minutes of baking adds a delightful nutty flavor.
• Make-Ahead Option: Assemble the scalloped potatoes up to a day in advance, cover, and refrigerate. Add about 15 minutes to the baking time when cooking from cold.
• Spice it Up: For a bit of a kick, add a pinch of red pepper flakes to the buttermilk mixture.
• Browning Issues? If the potatoes aren’t browning enough, you can broil them for a minute or two at the end, but watch them carefully to prevent burning!

Serving & Storage Suggestions

Serve the buttermilk scalloped potatoes warm as a comforting side dish. They pair beautifully with roasted pork, grilled chicken, or a simple green salad. Garnish with fresh parsley or chives for added freshness.

Leftovers can be stored in an airtight container in the refrigerator for up to 3 days. To reheat, bake in a preheated oven at 350°F (175°C) until warmed through, or microwave in short intervals. Avoid leaving the potatoes at room temperature for more than 2 hours. Freezing is not recommended as the texture of the potatoes may change.

Variations & Substitutions

• Dairy-Free: Substitute the low-fat buttermilk with a mixture of unsweetened almond milk and a tablespoon of lemon juice or apple cider vinegar to mimic the tanginess. Use a plant-based butter alternative.
• Gluten-Free: Ensure the flour is a certified gluten-free blend. A 1-to-1 gluten-free all-purpose flour works well.
• Sweet Potato Variation: Replace half of the baking potatoes with sweet potatoes for a sweeter, more vibrant dish.
• Herb Infusion: Add fresh thyme, rosemary, or sage to the buttermilk mixture for an herbaceous twist.
• Garlic Lovers: Saute minced garlic along with the onion for a boost of flavor.

FAQs (Frequently Asked Questions)

Q: Why is my buttermilk curdling when I heat it?
A: Overheating or boiling buttermilk will cause it to curdle. Heat it gently over low heat, stirring constantly, and avoid letting it come to a simmer.

Q: Can I use a different type of potato?
A: Yukon Gold potatoes work well, as they have a naturally creamy texture. Avoid using russet potatoes as they can become too dry.

Q: How do I know when the potatoes are done?
A: The potatoes are done when they are easily pierced with a fork and the top is lightly golden brown.

Q: Can I add cheese to this recipe?
A: Yes, you can sprinkle grated cheese, such as Gruyere or Parmesan, over the potatoes during the last 15 minutes of baking.

Q: What if my potatoes are still hard after an hour of baking?
A: Make sure your oven temperature is accurate. If the potatoes are still hard, cover the dish with foil and continue baking until tender, checking every 15 minutes.
