Step-by-step method
Step 1
First, preheat your oven to 350° F. Grab a large skillet and melt the butter over medium-high heat. Add your thinly sliced onions—don’t worry if they’re not perfectly sliced, happens to me all the time! Sprinkle a pinch of salt and pepper, then let the onions cook, stirring them every so often, until they’re soft and start to brown, about 10 minutes.
Step 2
Next, pour in the vegetable broth. Keep cooking those onions for another 5 minutes. They’ll get deep, golden, and super fragrant. Now toss in the garlic and chopped thyme. Let them mingle for 2 minutes, then remove the pan from heat. Meanwhile, in a measuring cup, mix the cream, milk, cayenne, some salt, and pepper. Stir in the Gruyere cheese.
Step 3
Butter a 9×13-inch casserole dish. Pour in a third of your creamy mixture, then layer a third of the potatoes, half the caramelized onions, and repeat. Finish with the last potatoes and remaining cream. Cover, bake for 1 hour 45 minutes to 2 hours. Uncover, top with cheddar, and bake 20 minutes more.

Tips and tricks to make this recipe shine
If you slice your potatoes a little thicker or thinner, it’s really okay—just adjust bake time. For max flavor, brown your onions deeply (don’t rush!). Letting the dish rest for 10 minutes before serving helps the creamy sauce set. Trust me, these little details make scalloped potatoes caramelized onions extra special.
What to serve with this recipe
Honestly, scalloped potatoes caramelized onions go with almost anything. I love them next to simple roasted chicken, grilled steak, or even a hearty salad. Sometimes, I’ll serve them with a crisp green veggie, like steamed broccoli or green beans, just to balance out all that creamy goodness.

How to store and reheat
Leftovers are a gift! Cover and refrigerate any extra scalloped potatoes caramelized onions for up to 4 days. When you’re ready for more, reheat portions in the microwave or pop the whole dish back in the oven, covered, at 350° F until hot. They’ll taste just as cozy as day one, maybe even better!
