How to Make French Onion Potato Bake
Follow these simple steps to prepare this delicious dish:
Step 1: Preheat Your Oven
Preheat your oven to 375°F (190°C). While that’s warming up, grab a baking dish and give it a good spray with nonstick cooking spray so your masterpiece doesn’t stick.
Step 2: Caramelize Those Onions
In a large skillet over medium heat, melt about four tablespoons of butter. Slice those onions thinly—aim for translucent ribbons—and add them to the skillet. Stir them occasionally until they turn golden brown and fragrant, which usually takes about 20 minutes. Patience is key here!
Step 3: Prepare Your Potatoes
While your onions are getting all fancy in their buttery bath, peel and slice your potatoes into thin rounds (about 1/8 inch thick). You can use a mandoline if you’re feeling fancy or just sharpened culinary skills if not.
Step 4: Layer It Up
Now that your onions are perfectly caramelized and smelling divine, it’s time to layer! Start with half of the potato slices at the bottom of your prepared baking dish. Sprinkle with half of those gorgeous caramelized onions on top followed by half the cheese. Repeat this layering process until everything is stacked high.
Step 5: Add Creamy Goodness
Pour your heavy cream evenly over the layered potatoes and onions—it will seep through all those nooks and crannies creating pure magic while baking. Sprinkle some thyme along with salt and pepper on top for extra flavor.
Step 6: Bake Away
Cover the baking dish with aluminum foil (shiny side down) to keep moisture in. Bake in the preheated oven for about an hour. After an hour, remove the foil and let it bake for another additional twenty minutes until bubbly and golden brown on top.
Transfer to plates and drizzle with sauce for the perfect finishing touch.
And there you have it! Your very own French Onion Potato Bake—a delightful blend of flavors that’ll make you want to hug yourself after every bite. Serve it alongside grilled meats or enjoy as a standalone vegetarian delight; this dish will quickly become a favorite at any meal!
