1 cup heavy cream – This luxurious ingredient adds the richness that makes the dish so satisfying and indulgent.

2 tbsp unsalted butter – Butter is essential for caramelizing the onions and adding extra richness to the dish.

How to Make French Onion Scalloped Potatoes
Follow these simple steps to prepare this delicious French Onion Scalloped Potatoes:
Step 1: Preheat and Prepare
Preheat your oven to 375°F (190°C). Meanwhile, grab a baking dish and spray it with cooking spray so nothing sticks to the bottom.
Step 2: Caramelize the Onions
In a skillet, melt 2 tablespoons of butter over medium heat. Once melted, add the sliced onions along with a pinch of salt. Stir occasionally for about 20 minutes, or until they turn golden brown and fragrant. This is where the magic begins!
Step 3: Make the Cream Mixture
In a mixing bowl, whisk together 1 cup of heavy cream, minced garlic, thyme, and season it with salt and pepper. This will become the luscious sauce that marries all the flavors together.
Step 4: Layer It Up
Now it’s time to assemble! Place half of the potato slices in the baking dish, then layer on half of the caramelized onions, followed by half of the shredded Gruyère cheese. Repeat these layers until you’ve used up all your ingredients.
Step 5: Pour the Cream Mixture
Pour the prepared cream mixture over the layered ingredients, making sure everything is just covered, almost as if you’re giving it a gentle bath.

Once finished, let it rest for about 5 minutes before serving. You’ll want to give it that little pause to let the layers settle so each bite is perfect. Transfer to plates, and watch your loved ones’ faces light up with joy as they dig into their new favorite dish!
