Instructions:
Heat the oven to 350 degrees. Grease a small baking pan (a square baking dish of 8×8 or 9×9 inches will do).
In a pot, melt the butter and mix in the flour.
Cook the sauce over low heat until it becomes smooth and starts boiling, stirring occasionally with an electric mixer.
Lower the heat and gently mix in 1 cup of cheddar cheese.
Place half of the sliced potatoes in the baking dish.
Put half of the cheese sauce on the potatoes.
Do the same thing with the next layer of potatoes and cheese sauce.
Put half a cup of cheddar cheese on top. Sprinkle a bit of paprika on top for color.
Cook in the oven at 350°F or higher for around 1 hour until the potatoes are soft.
Variations
This classic potato gratin can be customized in many ways to suit different tastes. For a richer flavor, try adding caramelized onions or garlic to the cheese sauce. You could also layer in cooked bacon or ham for a heartier dish.
If you prefer a twist on the traditional recipe, swap out half the potatoes for thinly sliced sweet potatoes or parsnips for a unique flavor profile.
For those who enjoy a bit of spice, mix in diced jalapeños or a dash of hot sauce into the cheese sauce. Herbs like thyme, rosemary, or chives can also enhance the dish’s aroma and taste.
If you’re looking for a lighter version, substitute half the milk with chicken or vegetable broth and use a reduced-fat cheese blend.
Vegans can adapt this dish by using plant-based butter, almond or oat milk, and dairy-free cheese. Nutritional yeast can add a cheesy flavor without dairy. Another creative variation is adding a breadcrumb or crushed cracker topping for extra crunch before baking.
Tips
To ensure even cooking, slice the potatoes uniformly—about 1/8-inch thick—using a mandoline or sharp knife. If you don’t have one, parboiling the potatoes for a few minutes can help soften them before baking.
For a smoother sauce, warm the milk slightly before adding it to the butter and flour mixture to prevent lumps.
If the top browns too quickly during baking, cover the dish loosely with aluminum foil. Let the gratin rest for 10 minutes after baking to allow the sauce to thicken slightly, making it easier to serve. For extra flavor, let the assembled dish sit in the fridge for an hour before baking so the potatoes absorb the sauce.
For a golden, crispy top, broil the gratin for the last 2-3 minutes of baking. If using pre-shredded cheese, toss it with a bit of cornstarch to prevent clumping in the sauce. Always taste the sauce before layering to adjust seasoning as needed.
How to Store
Leftover potato gratin can be stored in an airtight container in the refrigerator for up to 3-4 days. To reheat, cover with foil and warm in a 350°F oven until heated through, or microwave individual portions for 1-2 minutes. Adding a splash of milk before reheating can help revive the creamy texture.
For longer storage, the unbaked gratin can be assembled and frozen for up to 2 months. Thaw it overnight in the fridge before baking as directed. Note that the texture may be slightly softer after freezing. If freezing leftovers, portion them out for easy reheating later.
To prevent sogginess, avoid storing the gratin at room temperature for more than 2 hours. If making ahead, prepare the dish up to a day in advance, cover, and refrigerate until ready to bake. You may need to add a few extra minutes to the baking time if the dish is cold from the fridge.
Conclusion
This creamy, cheesy potato gratin is a comforting and versatile dish perfect for holidays or family dinners. Its simple preparation and rich flavor make it a crowd-pleaser, and the variations allow for endless creativity. Whether served as a side or a main course, it’s sure to impress.
With proper storage and reheating tips, you can enjoy this dish even after the initial meal. Experiment with different ingredients and techniques to make it your own, and don’t hesitate to try new flavors. This gratin is a timeless classic that will remain a favorite for years to come.
