Ingredients
  

  • 2 cups mashed potatoes about 4 medium russets, room temperature
  • 1 tablespoon butter or olive oil Kerrygold for richness, or avocado oil for a healthy twist
  • 1 small yellow onion finely chopped (swap leek for a milder taste)
  • 2 celery stalks diced small fresh market celery adds crunch
  • 2 cloves garlic minced (roasted garlic gives sweetness)
  • 1 teaspoon dried sage or 1 tablespoon fresh, chopped
  • 1 teaspoon dried thyme sub with herbes de Provence
  • ½ teaspoon kosher salt adjust to taste
  • ½ teaspoon freshly ground black pepper
  • ¼ cup low-sodium vegetable broth more if mix feels dry
  • ¼ cup fresh parsley chopped (flat-leaf preferred)
  • ½ cup whole-wheat bread cubes optional for extra texture; use gluten-free cubes if needed

Instructions
 

  • Preheat the oven to 350°F and grease a 9x9-inch baking dish with butter or nonstick spray.
  • In a skillet over medium heat, sauté onion and celery in butter or oil until soft and sweet.
  • Stir in garlic, sage, thyme, salt, and pepper. Cook until fragrant.
  • Transfer sautéed vegetables to a bowl. Add mashed potatoes, parsley, and bread cubes. Fold gently until combined.
  • Gradually add vegetable broth to moisten the mixture. Spread it in the baking dish and press lightly for crisp edges.
  • Bake for 25-30 minutes until lightly browned. Rest for 5 minutes before serving.

Notes

For a cheesy twist, add sharp cheddar or Gruyère. Make it gluten-free by skipping bread cubes. Dairy-free option: use coconut oil and non-dairy milk. Add roasted butternut squash cubes for an autumn touch. Mix in cooked lentils or smoked tofu for a protein boost.
