Recipe Ingredients

• 2 tablespoons plain (all-purpose) flour
• 500 ml (17 fl oz / 2 cups) milk
• 250 g (9 oz) mascarpone
• 250 g (9 oz) cottage cheese
• 200 g (9 oz) creamy feta, crumbled

How To Make Slow Cooker Potato, White Cheese And Prosciutto Gratin

1. Prepare the Sauce: Melt the butter in a saucepan over medium heat. Add the flour and cook for 1 minute until foaming, then gradually whisk in the milk and continue whisking until the sauce thickens. Stir in the mascarpone, cottage cheese, feta, and prosciutto, then season with salt and pepper. Cook for another 5 minutes until thickened.
2. Layer the Potatoes: Lightly grease the slow cooker. Arrange two layers of sliced potatoes in the bottom and spread 125 ml (4 fl oz / ½ cup) of the cheese mixture over the potatoes. Repeat the layers until all the potatoes and cheese mixture are used up, ending with the cheese mixture on top.
3. Cook: Set the slow cooker to high and cook for 6 hours, until the potatoes are tender and cooked through.
4. Serve: Serve with toasted breadcrumbs, chopped parsley, and a side of green salad.

Recipe Tips

• Use waxy potatoes: Waxy potatoes, like Yukon Gold, hold their shape better during cooking and won’t turn mushy in the slow cooker.
• Thinly slice the potatoes: Slice the potatoes as thinly as possible to ensure they cook evenly and absorb the creamy sauce well.
• Layer the potatoes carefully: Make sure to spread the cheese mixture evenly between each layer of potatoes to get a balanced flavor throughout the dish.
• Don’t skip greasing the slow cooker: Lightly greasing the slow cooker helps prevent the gratin from sticking and makes cleanup easier.
• Check for doneness: After 6 hours, check if the potatoes are tender by poking them with a fork. If they aren’t soft enough, cook for an additional 30 minutes.
