A creamy and flavorful Savory Sweet Potato Casserole made with tender mashed sweet potatoes, sautéed onions, herbs, and melted cheese. This comforting side dish highlights the natural earthiness of sweet potatoes and is perfect for family dinners or holiday gatherings.

Ingredients

  • 3 pounds sweet potatoes, peeled and cubed
  • 2 tablespoons olive oil or butter
  • 1 small onion, finely chopped
  • 2 cloves garlic, minced
  • 1/2 cup milk or half-and-half
  • 1/2 cup sour cream or plain Greek yogurt
  • 1 cup shredded sharp cheddar or Gruyère cheese
  • 1/2 teaspoon salt (or to taste)
  • 1/4 teaspoon black pepper
  • 1/2 teaspoon dried thyme or rosemary
  • Optional Topping:
  • 1/2 cup grated Parmesan cheese
  • 1/4 cup breadcrumbs
  • 1 tablespoon melted butter

Instructions

  1. Preheat oven to 375°F (190°C) and lightly grease a 9×13-inch baking dish.
  2. Place cubed sweet potatoes in a large pot, cover with water, and bring to a boil. Cook for 15–20 minutes until fork-tender. Drain thoroughly.
  3. While potatoes cook, sauté chopped onion in olive oil or butter over medium heat until soft and translucent. Add garlic and cook for 1 more minute.
  4. In a large bowl, mash the drained sweet potatoes until smooth.
  5. Stir in sautéed onion and garlic, milk, sour cream, shredded cheese, salt, pepper, and dried herbs. Mix until creamy and well combined.
  6. Spread mixture evenly into the prepared baking dish.
  7. If using topping, combine Parmesan, breadcrumbs, and melted butter. Sprinkle evenly over the casserole.
  8. Bake for 20–25 minutes until heated through and lightly golden on top.
  9. Let rest for a few minutes before serving.

Notes

  • Drain sweet potatoes thoroughly to prevent a watery casserole.
  • Prepare up to one day ahead and refrigerate before baking.
  • Add sautéed mushrooms or spinach for extra texture and flavor.
  • For dairy-free, use plant-based milk and yogurt and omit or substitute cheese.
  • Store leftovers refrigerated for up to 4 days or freeze for up to 2 months.
