Ingredients

• 4–5 medium potatoes, thinly sliced (Yukon Gold or Russet)
• 1 can (10.5 oz / 295g) condensed cream of mushroom soup
• 1 packet (1 oz / 30g) French onion soup mix
• 1 cup heavy cream or milk
• 1 cup shredded cheddar cheese (plus extra for topping)
• 2 tbsp butter, melted
• 1 small onion, thinly sliced (optional for extra flavor)
• Salt & pepper, to taste
• Fresh parsley, for garnish (optional)

Directions

1. Preheat Oven:
Preheat your oven to 375°F (190°C) and grease a baking dish with butter or cooking spray.

2. Prepare Sauce:
In a mixing bowl, whisk together the cream of mushroom soup, French onion soup mix, cream (or milk), and melted butter until smooth.

3. Layer Potatoes:
In the baking dish, layer half of the potato slices and onions.
Pour half of the soup mixture over the top, then sprinkle with some cheese.

4. Repeat Layers:
Add the remaining potatoes, pour over the rest of the sauce, and top with more cheese.

5. Bake:
Cover with foil and bake for 45 minutes.
Remove the foil and bake another 20–25 minutes, or until the potatoes are tender and the top is golden and bubbly.

6. Serve:
Garnish with parsley and let rest for 5–10 minutes before serving.

Recipe Tips

• Add cooked bacon bits or caramelized onions for extra flavor.
• You can swap cheddar for Gruyère or Swiss cheese for a more classic French onion taste.
• Slice the potatoes evenly so they cook at the same rate.
• Covering the dish during the first part of baking helps the potatoes become tender before the cheese is browned.

Serving Suggestions

Serve this creamy potato bake alongside roast chicken, beef, pork, steak, or grilled vegetables. It also makes a delicious side dish for a Sunday lunch or holiday dinner.

Storage

Allow leftovers to cool, then cover and refrigerate for up to 3 days. Reheat in the oven at 180°C (350°F) until hot and bubbly, or microwave individual portions until heated through.

What potatoes are best for this recipe?
Yukon Gold or Russet potatoes work well. Slice them thinly and evenly to ensure they cook through.
