This creamy potato bake soaked in French onion soup-infused cream is the kind of dish that brings comfort and warmth to any meal. Layers of thinly sliced potatoes absorb the rich flavors before being topped with golden, melted cheese. Whether you serve it as a hearty side or a vegetarian main, it’s guaranteed to satisfy.

I first made this during a chilly weekend gathering, and it quickly became a crowd favorite. The blend of creamy texture and savory onion notes is something everyone asks for again and again.

Ingredients

  • Potatoes: two kilograms peeled for a smooth creamy texture
  • Cream: six hundred milliliters to create the luscious sauce
  • French onion soup mix: forty grams for that unmistakable savory depth& look for good quality packets with natural onion flavor
  • Tasty cheese: two hundred fifty grams grated to melt perfectly and add a golden finish& I prefer a medium cheddar for balance

Instructions

Preheat Oven:
Set the oven to one hundred seventy degrees Celsius or three hundred thirty eight Fahrenheit. This moderate temperature allows the potatoes to cook through gently without drying out.
Slice Potatoes:
Use a mandolin or very sharp knife to slice the potatoes thinly and evenly. Thin slices are key to the potatoes becoming tender and soaking up the flavorful cream mixture.
Layer Potatoes:
Arrange the slices carefully in a baking dish. Build them evenly layer by layer. This stacking will help the dish cook uniformly and look beautiful when served.
Prepare Cream Mixture:
Combine the cream and French onion soup mix in a bowl. Mix thoroughly to ensure the soup powder dissolves completely, releasing its savory aroma.
Pour Mixture Over Potatoes:
Evenly pour the cream and onion soup mixture over the layers, making sure the liquid seeps into all the nooks and crannies between the potato slices.
Cover and Bake:
Cover the dish tightly with foil to keep moisture locked in. Place it in your preheated oven and bake for one and a half hours. The potatoes will soften and absorb the flavors as they slowly cook.
Add Cheese Topping:
Remove the foil carefully to avoid steam burns. Sprinkle the grated tasty cheese evenly on top, covering the entire surface for a rich cheesy crust.
Bake Cheese:
Return the dish to the oven uncovered. Bake until the cheese melts thoroughly, becoming bubbly and lightly golden. This should take about ten to fifteen minutes, providing a glorious finish.
Serve:
Remove from the oven and serve immediately while it is warm and creamy. The first bite is an experience of smooth potatoes with bursts of onion flavor and melted cheese.

This recipe highlights the magic of French onion soup mix, which elevates simple cream into a flavor powerhouse. One memorable moment was sharing this bake during a cold family reunion, watching everyone reach for seconds as the cheesy crust disappeared first.

Storage tips

Cool the potato bake completely before covering it with foil or plastic wrap. It keeps well in the refrigerator for up to three days. Reheat gently in the oven to retain that creamy texture. Avoid microwaving if possible as it can make the sauce separate.

Ingredient substitutions

Use sour cream or crème fraîche instead of cream for a tangier twist. You can replace tasty cheese with gruyere or mozzarella depending on the flavor profile you&re aiming for. If you cannot find French onion soup mix, a mix of dried onion powder, garlic powder, and a pinch of beef or vegetable bouillon works in a pinch.

Serving suggestions

Serve this potato bake alongside a fresh green salad for balance or pair with roast vegetables and your choice of protein for a complete meal. Leftover bake also works brilliantly as a flavorful base for a frittata by adding eggs and baking again.
