Preheat your oven to 375°F (190°C). Grease a 9x13 inch casserole dish and set aside.
Peel the potatoes and slice them into 1/4-inch thick rounds. Set aside.
Season the chicken breasts with 1/2 teaspoon of salt and 1/2 teaspoon of pepper. In a large skillet, heat 1 tablespoon of olive oil over medium-high heat. Sear the chicken breasts for 3-4 minutes per side until lightly browned but not cooked through. Remove from the skillet and set aside.
In the same skillet, reduce heat to medium. Add 1 tablespoon of olive oil and sauté diced onion and minced garlic until softened, about 3-4 minutes.
Add butter to the skillet with the sautéed onions and garlic and let it melt. Stir in the flour and cook for 1-2 minutes to form a roux.
Slowly whisk in the chicken broth, followed by the heavy cream. Stir constantly until the sauce thickens, about 3-5 minutes. Season with the remaining salt, pepper, and tarragon leaves.
Layer half the potato slices in the prepared casserole dish. Pour half of the sauce over the potatoes. Arrange the chicken breasts on top of the potatoes and sauce.
Add the remaining potato slices over the chicken, then pour the remaining sauce over the top. Spread evenly to ensure all potatoes are coated.
Cover the dish with aluminum foil and bake for 35 minutes in the preheated oven.
Remove the foil, sprinkle the shredded mozzarella cheese over the casserole, and return to the oven. Bake uncovered for another 15 minutes until the cheese is melted and golden brown.
Let the casserole rest for 5-10 minutes before serving. Garnish with additional fresh tarragon if desired. Serve warm and enjoy!
