How to Make Caramelized Onion Potatoes Au Gratin

Follow these simple steps to prepare this delicious dish:

Step 1: Preheat Your Oven

Preheat your oven to 400°F (200°C). While it’s heating up, grab your favorite baking dish and give it a good spray with nonstick cooking spray – we want those potatoes to slide right out when they’re done.

Step 2: Slice Those Potatoes

Wash and peel your potatoes before slicing them thinly (about 1/8 inch thick). A mandoline slicer is handy here if you have one; otherwise, a good knife will do just fine. Place them in a bowl of cold water as you slice to prevent browning.

Step 3: Caramelize the Onions

In a large skillet over medium heat, melt two tablespoons of butter. Toss in your sliced onions with a pinch of salt. Stir occasionally until they turn golden brown and sweet-smelling – about 15-20 minutes. Patience is key here; don’t rush them!

Step 4: Layer It Up

Now it’s time for assembly! Start layering half of those potato slices in your prepared baking dish. Sprinkle with salt and pepper, then add half of the caramelized onions on top, followed by half of the cheese mixture (Gruyère + cheddar combo). Repeat this process until all ingredients are used up.

Step 5: Pour Over Cream

Pour heavy cream evenly over the layered potatoes and onions until they’re just covered – this ensures every bite is creamy goodness! Then sprinkle some extra cheese on top because who doesn’t love more cheese?

Step 6: Bake Until Golden

Cover your baking dish with aluminum foil (shiny side down) and pop it in the preheated oven. Bake for about 30 minutes before removing the foil and baking for an additional 15-20 minutes or until bubbly and golden brown on top.

Once baked, let it cool slightly before serving – if you can resist diving right in! Transfer generous portions onto plates or serve directly from the baking dish. Drizzle with extra cream if you’re feeling indulgent!

Enjoy every delicious bite of your homemade Caramelized Onion Potatoes Au Gratin!

Perfecting the Cooking Process

Start by caramelizing the onions slowly to develop their sweet flavor. While they cook, prep your potatoes and cheese. Layer everything in a baking dish, pour over cream, and bake until golden and bubbly. Timing is key for perfect results.

Add Your Touch

Feel free to swap out cheeses based on your preference—Gruyère or cheddar can add unique flavors. Add herbs like thyme or rosemary for an aromatic twist. Want some heat? Toss in a pinch of red pepper flakes for a spicy kick.

Storing & Reheating

Store leftovers in an airtight container in the fridge for up to three days. To reheat, pop them in the oven at 350°F until warmed through—this ensures that creamy texture remains intact.

Sometimes, I catch my family sneaking bites of these potatoes au gratin right from the dish before dinner! Their love for this recipe makes every effort worth it.
