3 large russet potatoes, peeled
2 zucchinis, about 2-3 cups shredded
1½ teaspoons salt, plus more for sprinkling on top
1. Place potatoes in a large pot and cover with cold water. Bring water to a boil and cook potatoes for 20-30 minutes, until fork tender but still have some give in the middle. Drain water and let potatoes cool until they are comfortable to handle. You want them to still be warm.
2. Preheat oven to 425 degrees Fahrenheit. Grate potatoes on the large side of a box grater and put into a large bowl. Grate each zucchini and squeeze out the liquid using a clean dishtowel. Place grated zucchini into the bowl with the potatoes and add 1½ teaspoons salt. Use your hands to mix everything together.
3. Line a large cookie sheet with parchment paper. Use your hands to form small cylinders with the mixture. Use about 1 tablespoon per tater tot. Place the cookie sheet in the freezer for about 10 minutes to allow them to firm up.
4. Brush the top of each tater tot with a small amount of olive oil and sprinkle each one with salt. Bake tater tots until browned and crispy, about 30 minutes flipping halfway though. Serve with ketchup if desired.
