How to Make Boursin Potato Bacon Casserole

This casserole is simple to prepare and bakes up beautifully.

Step 1: Preheat & Prep

Start by preheating your oven to 375°F. Lightly grease a 1 1/2 Quart baking dish with butter or cooking spray.

Step 2: Precook the Potatoes

Add your thinly sliced Yukon Gold potatoes to a large pot of salted water. Bring to a simmer and cook for 5–7 minutes, just until they’re starting to soften. Drain and set aside.

Step 3: Make the Boursin Sauce

In a saucepan over medium heat, melt the butter. Whisk in the flour and cook for 30 seconds. Slowly pour in the milk, whisking constantly. After 2–3 minutes, the mixture should thicken slightly. Stir in the Boursin cheese, salt, and pepper until smooth.

Step 4: Layer the Casserole

Layer half the potatoes in the bottom of your prepared dish. Top with half the onions and half the bacon. Pour on half the cheese sauce. Repeat the layers and finish with the remaining sauce.

Step 5: Bake & Serve

Bake uncovered for 35–40 minutes, or until the top is golden and bubbly. Let it rest for about 10 minutes before serving. Garnish with fresh herbs if you’d like!
