I Appreciate How Simple Ingredients Transform Into Something So Elegant. The Combination Of Sharp Cheddar, Gruyère, And Parmesan Creates Deep, Layered Flavor. I Like That The Cream Sauce Soaks Into The Thinly Sliced Potatoes, Giving Them A Melt-In-My-Mouth Texture. It Is The Perfect Side For Special Dinners, Holidays, Or Anytime I Want A Comforting Classic With A Refined Touch.
Ingredients
(Here’s A Tip: Check Out The Full List Of Ingredients And Measurements In The Recipe Card Below.)
2½ Lbs Russet Potatoes, Peeled And Thinly Sliced 3 Tablespoons Butter 3 Cloves Garlic, Minced 2 Cups Heavy Cream 1 Cup Whole Milk 1½ Cups Shredded Sharp Cheddar Cheese 1 Cup Shredded Gruyère Or Swiss Cheese ½ Cup Grated Parmesan Cheese Salt, To Taste Black Pepper, To Taste Pinch Of Nutmeg (Optional) Fresh Parsley, Chopped (Optional Garnish)
Directions
I Start By Preheating The Oven To 375°F (190°C) And Greasing A Baking Dish.
In A Saucepan Over Medium Heat, I Melt The Butter And Sauté The Garlic For About 30 Seconds Until Fragrant. I Stir In The Heavy Cream, Milk, Salt, Pepper, And Nutmeg. I Heat The Mixture Gently Without Letting It Boil.
I Arrange Half Of The Thinly Sliced Potatoes In An Even Layer In The Baking Dish. I Sprinkle Half Of The Cheddar, Gruyère, And Parmesan Over The Potatoes. Then I Pour Half Of The Warm Cream Mixture Evenly Over The Top.
I Repeat The Layers With The Remaining Potatoes, Cheeses, And Cream Sauce.
I Cover The Dish Tightly With Foil And Bake For 35 Minutes. After That, I Remove The Foil And Bake For An Additional 15 Minutes Until The Top Is Bubbly And Lightly Golden.
Once Out Of The Oven, I Let The Potatoes Rest For About 10 Minutes Before Serving. I Finish With A Sprinkle Of Fresh Parsley If I Want A Touch Of Color.
Servings And Timing
This Recipe Makes 6 Servings. Prep Time: 15 Minutes Cook Time: 50 Minutes Total Time: 1 Hour 5 Minutes
Variations
I Sometimes Add Thinly Sliced Onions Between The Layers For Extra Flavor. If I Want A Smoky Twist, I Mix In A Small Amount Of Smoked Gouda. For A Slightly Lighter Version, I Replace Part Of The Heavy Cream With Half-And-Half. I Also Enjoy Adding Crispy Cooked Bacon Bits On Top Before Serving.
Storage/Reheating
I Store Leftovers In An Airtight Container In The Refrigerator For Up To 4 Days. To Reheat, I Cover The Dish With Foil And Warm It In A 350°F Oven Until Heated Through. If Needed, I Add A Small Splash Of Milk Or Cream To Restore Creaminess. Individual Portions Can Also Be Reheated Gently In The Microwave.
FAQs
Can I Make This Dish Ahead Of Time?
I Assemble The Dish A Day In Advance And Refrigerate It Covered. I Add A Few Extra Minutes To The Baking Time If It Goes Into The Oven Cold.
What Is The Secret To Ultra-Creamy Texture?
I Slice The Potatoes Very Thin, Ideally Using A Mandoline, So They Soften And Blend Seamlessly Into The Cream Sauce.
Can I Use A Different Type Of Potato?
I Prefer Russet Potatoes For Their Starch Content, But Yukon Gold Potatoes Also Work And Add A Slightly Buttery Flavor.
Can I Freeze Potatoes Au Gratin?
I Do Not Prefer Freezing Because The Texture Of The Cream Sauce Can Change, But It Is Possible If Tightly Wrapped And Reheated Gently.
How Do I Know When It Is Fully Cooked?
I Insert A Knife Into The Center To Ensure The Potatoes Are Completely Tender And The Top Is Golden And Bubbling.
Conclusion
I Love How These Cheesy Potatoes Au Gratin Deliver Steakhouse-Level Comfort In Every Bite. The Creamy Layers, Melted Cheese, And Golden Top Make This Dish Rich, Satisfying, And Perfect For Special Meals. Whenever I Serve It, It Quickly Becomes One Of The Most Requested Sides At My Table.

Notes
Slice potatoes very thin (a mandoline works best) for ultra-creamy texture.
For extra browning, broil for 2–3 minutes at the end.
Letting the dish rest before serving helps the layers set properly.
Store leftovers refrigerated up to 4 days. Reheat covered to prevent drying.
Pairs perfectly with steak, roasted chicken, or holiday ham.
