Ingredients for Scalloped Potatoes Caramelized Onions

Gathering these simple ingredients is the first step to creating my favorite scalloped potatoes caramelized onions. The star players are the potatoes and the onions, of course, but the creamy sauce brings it all together. Here’s what you’ll need:

• 4 large russet potatoes – peeled and thinly sliced (about 1/8 inch thick). Russets have a great starchy texture that makes this dish wonderfully creamy.
• 2 medium onions – thinly sliced. This is where the magic starts; we’ll caramelize these slowly.
• 2 cups heavy cream – this makes our scalloped potatoes with caramelized onions incredibly rich and decadent.
• 1 teaspoon garlic powder – adds a subtle savory note.
• 1 teaspoon salt – essential for bringing out all the flavors.
• 1/2 teaspoon black pepper – for a little warmth.
• 1 teaspoon fresh thyme (or 1/2 teaspoon dried thyme) – thyme pairs beautifully with both potatoes and onions.
• 1 cup grated cheddar cheese – for that perfect golden, bubbly topping.
• 1 tablespoon olive oil – helps the onions caramelize without burning.
• 1 tablespoon butter – adds richness to the onion caramelization process.

How to Make Scalloped Potatoes Caramelized Onions

Follow these simple steps to create a truly memorable dish. The key to the best scalloped potatoes caramelized onions is patience, especially when caramelizing those onions!

1. Step 1: Preheat your oven to 375°F (190°C). While the oven heats up, prep your potatoes by peeling and thinly slicing them to about 1/8 inch thick. Using a mandoline can help achieve uniform slices for even cooking.
2. Step 2: In a large skillet, heat 1 tablespoon olive oil and 1 tablespoon butter over medium heat. Add the thinly sliced onions and cook them slowly, stirring occasionally. This caramelization process takes about 15-20 minutes, or until the onions are soft, sweet, and beautifully golden brown. The aroma will fill your kitchen!
3. Step 3: While the onions are caramelizing, prepare the creamy sauce. In a separate bowl, whisk together the 2 cups heavy cream, 1 teaspoon garlic powder, 1 teaspoon salt, 1/2 teaspoon black pepper, and 1 teaspoon fresh thyme (or 1/2 tsp dried). This mixture is what gives our dish its signature creamy texture and savory depth.
4. Step 4: Now, let’s assemble this amazing scalloped potatoes caramelized onions dish. Grease your baking dish. Layer half of the sliced potatoes evenly in the bottom. Pour half of the cream mixture over the potatoes, then scatter half of the sweet, caramelized onions on top.
5. Step 5: Repeat the layering process: add the remaining sliced potatoes, pour the rest of the creamy sauce over them, and finish with the remaining caramelized onions. This ensures every bite has that wonderful onion flavor.
6. Step 6: Sprinkle the 1 cup grated cheddar cheese evenly over the entire dish. This will melt into a delicious, golden crust as it bakes.
7. Step 7: Cover the baking dish tightly with aluminum foil. This helps the potatoes cook through evenly and become tender. Bake for 45 minutes.
8. Step 8: Carefully remove the aluminum foil. Continue baking for an additional 15 minutes, or until the top is beautifully golden brown and bubbly, and the potatoes are fork-tender.
9. Step 9: For the best texture and flavor, let the scalloped potatoes caramelized onions rest for about 10 minutes before serving. This allows the sauce to thicken slightly.
