Start by preheating your oven to 375°F (190°C) and line a baking sheet with parchment paper. The parchment is crucial here - it prevents sticking and makes removing your delicate taco shells much easier. If you don't have parchment, a silicone baking mat works great too!

Break your cauliflower head into florets and pop them into a food processor. Pulse until the cauliflower breaks down into rice-sized pieces - this should take about 30 seconds. Don't overprocess or you'll end up with cauliflower mush! If you don't have a food processor, you can grate the cauliflower using the large holes of a box grater, though it takes a bit more elbow grease. Transfer your cauliflower rice to a microwave-safe bowl.

This step is absolutely critical for crispy shells! Microwave your riced cauliflower for about 5 minutes until it's soft. Let it cool for a few minutes until it's comfortable to handle. Now for the arm workout - place the cooked cauliflower in a clean kitchen towel (one you don't mind getting a bit stained), gather up the edges, and squeeze like your taco dreams depend on it! You want to remove as much moisture as possible - you'll be surprised how much water comes out. The drier your cauliflower, the crispier your shells will be.

Transfer your squeezed cauliflower to a large mixing bowl. Add the finely chopped spinach (the finer you chop it, the better it incorporates), eggs, shredded mozzarella, salt, pepper, and garlic powder. Mix everything together until well combined - I find clean hands work best for this job, but a sturdy spoon works too. The mixture should hold together when you squeeze a bit in your palm.

Scoop about 1/4 cup of your cauliflower mixture onto the parchment-lined baking sheet. Use your fingers or the back of a spoon to shape it into a circle about 5-6 inches in diameter and 1/4 inch thick. Don't make them too thin or they'll break, but not too thick or they won't crisp up properly. Continue with the rest of the mixture, spacing the shells about an inch apart. You should end up with 6-8 shells depending on their size.

Slide your baking sheet into the preheated oven and bake for 15-20 minutes. You're looking for golden brown edges and shells that feel firm to the touch. Keep an eye on them toward the end - oven temperatures can vary, and you want that perfect balance of crispy exterior and slightly flexible interior so they can hold your fillings without breaking.

Once baked to golden perfection, let your taco shells cool on the baking sheet for about 5 minutes. This cooling period helps them firm up a bit more. Carefully loosen and remove them from the parchment paper - a thin spatula helps if they're sticking at all. Now comes the fun part - fill them with all your favorite taco toppings! They're delicious with seasoned ground beef, shredded chicken, or keep it vegetarian with black beans and extra veggies. Don't forget the classic toppings like shredded lettuce, diced tomatoes, avocado, and a dollop of sour cream!
