Ingredients

• 4 cups thinly sliced potatoes (Yukon Gold or Russet work well)
• 1 cup chopped onions
• 2 cups fresh spinach, roughly chopped
• 1 cup sliced mushrooms
• 1 cup shredded cheddar cheese (or vegan cheese alternative)
• 1 cup sour cream (or plain Greek yogurt)
• 1/2 cup milk (dairy or plant-based)
• 3 cloves garlic, minced
• 1/2 cup sun-dried tomatoes, chopped (optional)
• 1/4 cup fresh parsley, chopped
• 2 tablespoons butter or olive oil
• Salt and pepper to taste
• 1/2 teaspoon smoked paprika
• 1/4 cup breadcrumbs for topping (optional)

Equipment

• Large mixing bowl
• 9×13 inch casserole dish
• Sharp knife and cutting board
• Large skillet
• Measuring cups and spoons
• Mixing spoon or spatula
• Oven mitts
• Aluminum foil (optional)

Instructions

1. Preheat your oven to 375°F (190°C). Lightly grease the casserole dish with butter or olive oil.
2. Prepare the potatoes: Wash, peel if desired, and thinly slice the potatoes. Place them in a bowl of cold water to prevent browning while you prep the other ingredients.
3. Sauté the vegetables: In a large skillet, heat the butter or olive oil over medium heat. Add the chopped onions and garlic, cooking until translucent and fragrant, about 3-4 minutes.
4. Add mushrooms and spinach: Stir in the sliced mushrooms and cook until softened, about 5 minutes. Add the spinach last and cook until just wilted. Remove from heat.
5. Combine the creamy base: In a mixing bowl, combine the sour cream, milk, smoked paprika, salt, and pepper. Stir in the sautéed vegetables and sun-dried tomatoes (if using).
6. Assemble the casserole: Drain the potatoes and pat them dry. Layer half of the potatoes evenly on the bottom of the casserole dish. Spread half of the creamy vegetable mixture over the potatoes, then sprinkle with half of the shredded cheese.
7. Repeat layering: Add the remaining potatoes, followed by the rest of the creamy mixture. Top with the remaining cheese and sprinkle breadcrumbs over the top if you like a crunchy crust.
8. Bake: Cover the casserole with aluminum foil and bake for 40 minutes. Remove the foil and bake for an additional 15 minutes or until the top is golden brown and bubbly, and the potatoes are tender when pierced with a fork.
9. Garnish and serve: Let the casserole rest for 10 minutes before serving. Sprinkle with fresh parsley for a pop of color and freshness.

Tips & Variations

For a gluten-free option, skip the breadcrumbs or use gluten-free breadcrumbs.

Try adding other vegetables like bell peppers, zucchini, or broccoli for extra nutrition and flavor.

Swap cheddar for mozzarella, gouda, or a vegan cheese blend to change the flavor profile.

Make it vegan by using plant-based sour cream, milk, and cheese alternatives.

If you want a lighter version, substitute sour cream with Greek yogurt or a cashew cream.
