For the Gratin:

  • 1 pound Italian sausage, casings removed
  • 1 large onion, finely chopped
  • 3 cloves garlic, minced
  • 2 cups shredded sharp cheddar cheese
  • 1 1/2 cups grated Parmesan cheese
  • 2 cups heavy cream
  • 1 cup chicken broth
  • 1/2 cup unsalted butter
  • 1/4 cup all-purpose flour
  • 1 teaspoon dried thyme
  • Salt and black pepper to taste

For Garnish:

  • Fresh parsley, chopped


Preparing the Potatoes and Sausage:

  1. Preheat the oven to 375°F (190°C). Grease a large baking dish.
  2. In a skillet over medium heat, brown the sausage, breaking it into crumbles. Once cooked, remove excess fat and set aside.
  3. In the same skillet, add the chopped onion and minced garlic. Sauté until the onion is translucent.
  4. Combine the cooked sausage, onion, and garlic in a bowl. Set aside.

Creating the Cheese Sauce:

  1. In a saucepan over medium heat, melt the butter. Stir in the flour to create a roux.
  2. Gradually whisk in the heavy cream and chicken broth, ensuring a smooth consistency.
  3. Stir in the thyme, salt, and black pepper. Allow the mixture to simmer until it thickens.

Assembling the Gratin Layers:

  1. Layer half of the sliced potatoes in the prepared baking dish.
  2. Sprinkle half of the sausage mixture over the potatoes, followed by a portion of the cheddar and Parmesan cheeses.
  3. Pour half of the cheese sauce over the layers.
  4. Repeat the layering process with the remaining potatoes, sausage, and cheeses.
  5. Finish by pouring the remaining cheese sauce over the top.

Baking to Perfection:

  1. Cover the baking dish with foil and bake for 45 minutes.
  2. Remove the foil and bake for an additional 30-40 minutes or until the top is golden and the potatoes are tender.
  3. Let the gratin rest for 10-15 minutes before serving.

Garnishing and Serving:

  1. Sprinkle fresh chopped parsley over the gratin for a burst of color and flavor.
  2. Serve the Sausage Potatoes au Gratin warm and enjoy the creamy, savory goodness.

Cook Notes

Perfecting Sausage Potatoes au Gratin involves some key cook notes:

  • Even Potato Slices: Use a mandoline slicer for even and thin potato slices.
  • Precooking Sausage: Browning the sausage before baking enhances its flavor and ensures it’s fully cooked.
  • Cheese Selection: Opt for high-quality sharp cheddar and Parmesan for maximum flavor.
  • Resting Time: Allowing the gratin to rest after baking ensures a cohesive texture and easier serving.


Veggie Delight:

Elevate your gratin with a Veggie Delight:

  • Add layers of thinly sliced zucchini, mushrooms, or spinach for a flavorful veggie twist.

Bacon Bliss:

Transform your gratin with Bacon Bliss:

  • Incorporate crispy bacon bits between the layers for an extra layer of smokiness.

Herb Infusion:
