4.5 from 138 reviews

A comforting and creamy mashed potato and cauliflower gratin featuring tender mashed potatoes and cauliflower blended together, topped with melted cheddar cheese and crispy breadcrumbs for a golden finish.

Ingredients

Scale

Vegetables

  • 3 large potatoes, peeled and cubed
  • 1 head cauliflower, cut into florets

Dairy

  • 1/2 cup milk
  • 1/4 cup butter
  • 1 cup cheddar cheese, shredded

Others

  • 1/4 cup breadcrumbs
  • Salt and pepper to taste

Instructions

  1. Preheat Oven: Preheat your oven to 375°F (190°C) to get it ready for baking the gratin.
  2. Boil Vegetables: In a large pot, bring water to a boil and add the peeled, cubed potatoes and cauliflower florets. Boil until both are tender when pierced with a fork, approximately 15-20 minutes. Drain well.
  3. Mash Ingredients: Transfer the drained potatoes and cauliflower into a large bowl. Add the milk, butter, salt, and pepper. Mash together until you achieve a smooth and creamy consistency.
  4. Assemble Gratin: Spoon the mashed mixture evenly into a greased baking dish. Sprinkle shredded cheddar cheese evenly over the top, followed by the breadcrumbs to create a crunchy topping.
  5. Bake: Place the baking dish in the preheated oven and bake for 20-25 minutes until the cheese is melted, bubbly, and the breadcrumbs are golden brown.
  6. Serve: Remove from oven and let cool slightly before serving your delicious mashed potato and cauliflower gratin.

Notes

  • You can substitute the cheddar cheese with Gruyère or mozzarella for a different flavor profile.
  • For a richer gratin, use cream instead of milk.
  • To add extra flavor, mix in some garlic or fresh herbs like thyme or rosemary when mashing.
  • Ensure the vegetables are well drained to avoid a watery gratin.
  • For a gluten-free option, use gluten-free breadcrumbs or omit them and replace with crushed nuts for crunch.
