How to Make Caramelised Onion, Gruyère & Thyme Scalloped Potatoes
Preheat your oven: Begin by preheating your oven to 375°F (190°C). While it heats up, grab yourself a cozy cup of tea because this will take some time but trust me—it’s worth every minute.
Prepare your baking dish: Using butter, generously grease your baking dish so nothing sticks later on. Imagine those gooey layers slipping away—no one wants that!
Slice the potatoes: Thinly slice Yukon Gold potatoes using a sharp knife or mandoline for consistent thickness. Aim for about 1/8-inch slices so they cook evenly and absorb all those glorious flavors.
Caramelise the onions: In a large skillet over medium heat, melt two tablespoons of butter. Add thinly sliced onions and cook for about 20 minutes until they turn golden brown and sweet-smelling—this is where magic happens!
Layer it up: Start layering those potato slices in your prepared baking dish. Sprinkle salt and pepper between each layer along with caramelised onions and shredded Gruyère cheese until everything is used up.
Pour cream over: Once layered beautifully, pour heavy cream evenly over the top. The cream should just cover the potatoes—this ensures each bite is creamy without drowning them.
Bake it till bubbly: Cover with foil and bake in the preheated oven for about 45 minutes. Then remove the foil and let it bake uncovered for an additional 20-30 minutes until golden brown and bubbling—a sight so heavenly you might shed a tear!
Now you’re ready to serve! Let those scalloped potatoes cool for about 10 minutes before diving in—the anticipation makes each bite even more rewarding! Enjoy this comforting classic that brings everyone together around the table!
