Ingredients

• 6 medium Russet potatoes
• 6 cups Spinach
• 4 tablespoons Unsalted butter
• 3 cloves Garlic cloves (minced)
• 1 cup Whole milk
• 1 cup Sour cream
• 1.5 cups Shredded cheddar cheese
• 0.5 cup Parmesan cheese (grated)
• 2 teaspoons Salt
• 0.5 teaspoon Black pepper
• 2 tablespoons Olive oil
• 0.5 cup Panko breadcrumbs (optional)

Directions

Step 1

Preheat your oven to 375°F (190°C) and lightly grease a 9x13-inch baking dish.

Step 2

Peel the potatoes and cut them into large chunks. Place them in a large pot, cover with water, and add a pinch of salt. Bring to a boil and cook for 15-18 minutes, or until the potatoes are fork-tender. Drain and return to the pot.

Step 3

While the potatoes cook, heat the olive oil in a large skillet over medium heat. Add the minced garlic and sauté for about 30 seconds, until fragrant. Add the spinach and cook until wilted, about 3-4 minutes. Remove from heat and set aside.

Step 4

Mash the boiled potatoes with a potato masher or fork until smooth. Mix in the butter, milk, sour cream, shredded cheddar cheese, 1 teaspoon of salt, and black pepper. Stir until creamy and well combined.

Step 5

Gently fold the sautéed spinach into the mashed potato mixture until evenly distributed. Taste and adjust seasoning as needed.

Step 6

Spread the mashed potato-spinach mixture evenly into the prepared baking dish. Sprinkle the top with Parmesan cheese and, if desired, Panko breadcrumbs for added crunch.

Step 7

Bake the casserole in the preheated oven for 25-30 minutes, or until the top is golden and bubbly.

Step 8

Remove from the oven and let it cool for 5 minutes before serving. Enjoy!
