Ingredients:

• For the Chicken Filling:
• 2 lbs boneless, skinless chicken breasts, cooked and shredded
• 1 tablespoon olive oil
• 1 medium yellow onion, chopped
• 2 cloves garlic, minced
• 1 cup frozen mixed vegetables (peas, carrots, corn)
• 1 (10.75 ounce) can condensed cream of chicken soup
• 1/2 cup chicken broth
• 1/4 cup milk
• 1 teaspoon dried thyme
• 1/2 teaspoon dried rosemary
• 1/4 teaspoon black pepper
• 1/4 teaspoon salt (or to taste)
• For the Mashed Potatoes:
• 5 lbs russet potatoes, peeled and quartered
• 1 cup milk, warmed
• 1/2 cup butter, softened
• 1/4 cup sour cream
• 1 teaspoon salt (or to taste)
• 1/2 teaspoon black pepper (or to taste)
• Optional: 1/4 cup shredded cheddar cheese for topping

Preparing the Chicken Filling:

1. Cook and Shred the Chicken: I usually bake my chicken breasts for this recipe. Preheat your oven to 375°F (190°C). Place the chicken breasts in a baking dish, drizzle with a little olive oil, and season with salt and pepper. Bake for about 20-25 minutes, or until the internal temperature reaches 165°F (74°C). Let the chicken cool slightly, then shred it using two forks. You can also boil the chicken if you prefer, or even use leftover rotisserie chicken to save time!
2. Sauté the Aromatics: Heat the olive oil in a large skillet over medium heat. Add the chopped onion and cook until softened, about 5-7 minutes. Then, add the minced garlic and cook for another minute until fragrant. Be careful not to burn the garlic!
3. Combine the Filling Ingredients: Add the frozen mixed vegetables to the skillet and cook for about 3-5 minutes, until they are slightly softened. Stir in the condensed cream of chicken soup, chicken broth, and milk. Bring the mixture to a simmer, stirring constantly.
4. Season and Simmer: Add the dried thyme, dried rosemary, salt, and pepper to the skillet. Stir well to combine. Add the shredded chicken to the skillet and stir until it is evenly coated in the sauce. Reduce the heat to low and simmer for about 10-15 minutes, allowing the flavors to meld together. This step is crucial for a flavorful filling! Taste and adjust the seasonings as needed. I sometimes add a pinch of red pepper flakes for a little kick.

Making the Mashed Potatoes:

1. Boil the Potatoes: Place the peeled and quartered potatoes in a large pot. Cover them with cold water and add a pinch of salt. Bring the water to a boil over high heat, then reduce the heat to medium and simmer for about 15-20 minutes, or until the potatoes are fork-tender. You should be able to easily pierce them with a fork.
2. Drain and Mash: Drain the potatoes thoroughly in a colander. Return them to the pot and let them sit for a minute or two to allow any excess water to evaporate. This will help prevent your mashed potatoes from being watery.
3. Add the Goodness: Add the warmed milk, softened butter, and sour cream to the pot with the potatoes. Using a potato masher or an electric mixer, mash the potatoes until they are smooth and creamy. Be careful not to overmix, as this can make the potatoes gluey.
4. Season to Perfection: Season the mashed potatoes with salt and pepper to taste. I like to start with the recommended amounts and then add more as needed. You can also add other seasonings, such as garlic powder or onion powder, if you like.

Assembling the Casserole:

1. Preheat the Oven: Preheat your oven to 350°F (175°C).
2. Layer the Ingredients: Lightly grease a 9×13 inch baking dish. Spread the chicken filling evenly over the bottom of the dish.
3. Top with Mashed Potatoes: Carefully spread the mashed potatoes evenly over the chicken filling. You can use a spoon or a piping bag to create a decorative pattern on top of the potatoes.
4. Add Cheese (Optional): If you like, sprinkle the shredded cheddar cheese over the mashed potatoes. This will create a nice golden-brown crust on top of the casserole.
5. Bake the Casserole: Bake the casserole for 20-25 minutes, or until the mashed potatoes are lightly golden brown and the cheese is melted and bubbly (if using).
6. Let it Rest: Remove the casserole from the oven and let it rest for about 5-10 minutes before serving. This will allow the filling to set slightly and make it easier to slice.

Tips and Variations:

• Make it Ahead: You can assemble the casserole ahead of time and store it in the refrigerator for up to 24 hours. Add about 10-15 minutes to the baking time if baking from cold.
• Use Different Vegetables: Feel free to substitute the mixed vegetables with other vegetables, such as broccoli, cauliflower, or green beans.
• Add Cheese to the Filling: Stir in some shredded cheddar cheese or mozzarella cheese to the chicken filling for extra flavor.
• Spice it Up: Add a pinch of red pepper flakes or a dash of hot sauce to the chicken filling for a little heat.
• Use Sweet Potatoes: Substitute some or all of the russet potatoes with sweet potatoes for a sweeter and more nutritious mashed potato topping.
• Add Gravy: Serve the casserole with a side of gravy for extra richness and flavor. You can use store-bought gravy or make your own.
• Cream Cheese Mashed Potatoes: For extra creamy mashed potatoes, add 4 ounces of softened cream cheese along with the butter and milk.
• Garlic Mashed Potatoes: Add 2-3 cloves of roasted garlic to the mashed potatoes for a delicious garlic flavor. Roast the garlic by cutting off the top of a head of garlic, drizzling with olive oil, wrapping in foil, and baking at 400°F (200°C) for about 45 minutes, or until soft and fragrant.
• Herb Infused Mashed Potatoes: Stir in fresh herbs like chives, parsley, or dill into the mashed potatoes for a fresh and flavorful twist.
• Bacon Bits: Sprinkle cooked and crumbled bacon bits over the mashed potatoes before baking for a smoky and savory flavor.
• Breadcrumb Topping: For a crispy topping, mix breadcrumbs with melted butter and sprinkle over the mashed potatoes before baking.
• Different Soups: Experiment with different condensed soups in the chicken filling, such as cream of mushroom or cream of celery.
• Wine Addition: Add a splash of dry white wine to the chicken filling while it’s simmering for added depth of flavor.
• Mushroom Variation: Sauté sliced mushrooms along with the onions and garlic for a mushroom-infused chicken filling.
