Bring a large pot of water to a boil over medium-high heat. Add the cauliflower florets and cook for 5 to 6 minutes, or until tender when pierced with a fork. Drain and roughly chop the cooked cauliflower. Set aside.
In a large bowl, whisk together the eggs, milk, garlic powder, nutritional yeast, and salt. Stir in the chopped spinach until well combined.
Add the chopped cauliflower to the egg mixture, ensuring the florets are evenly coated.
Pour the mixture into a greased or parchment-lined baking dish and spread evenly.
Bake in the oven for 45 minutes, or until the casserole is set and the top is lightly golden.
Remove from the oven and let cool for 5–10 minutes before slicing and serving. Enjoy!
