Boil 6 medium golden potatoes cut in half until fork tender.
Let potatoes cool slightly, then peel the skins off.
Spray a springform pan with avocado oil.
Press the boiled potatoes into the bottom and up the sides of the pan to form a crust.
Spray the crust with avocado oil and sprinkle salt over the base and sides.
Bake at 425°F for 20–25 minutes to pre-bake the crust.
In a bowl, whisk together 6 eggs, ricotta, cheddar, diced ham, chopped spinach, salt, and pepper.
Pour the egg mixture into the pre-baked potato crust.
Top with extra shredded cheese.
Bake at 425°F for 40–45 minutes, or until fully set.
Let cool slightly before removing from the springform pan.
Finish with fresh chives and flaky salt.
