Ingredients

For the Taco Shells:

  • 1 medium head of cauliflower, riced (about 4 cups raw riced cauliflower)

  • 5 oz (140g) fresh spinach, finely chopped

  • 2 large eggs

  • 1 cup (100g) finely grated Parmesan cheese

  • 1/2 cup (56g) almond flour

  • 1 tsp ground cumin

  • 1 tsp smoked paprika

  • 1/2 tsp garlic powder

  • 1/2 tsp onion powder

  • 1/2 tsp kosher salt

  • 1/4 tsp black pepper

  • Non-stick cooking spray or olive oil

For Serving (Suggestions):

  • Chipotle lime chicken or black beans

  • Pico de gallo or salsa verde

  • Sliced avocado or guacamole

  • Shredded lettuce or cabbage

  • Greek yogurt or sour cream

  • Fresh cilantro and lime wedges

Equipment Needed

  • Food processor or box grater (to rice the cauliflower)

  • Clean kitchen towel or cheesecloth

  • Mixing bowls

  • Baking sheets

  • Parchment paper

  • Spoon or ladle

  • 2 similar-sized, clean glass bottles or oven-safe molds for shaping

Step-by-Step Instructions

1. Prep and Dry the Cauliflower (Crucial Step!)
Remove the cauliflower florets from the core and pulse in a food processor until it resembles rice. Alternatively, use a box grater. Place the riced cauliflower in a microwave-safe bowl and microwave on high for 4-5 minutes, stirring once halfway. Allow to cool slightly. Transfer the cooked cauliflower to a clean kitchen towel and wring out as much liquid as humanly possible. This is the most important step for achieving sturdy shells. You should have about 1.5 to 2 cups of very dry, packed cauliflower “flour.”

2. Combine the Shell Mixture
In a large mixing bowl, combine the thoroughly dried cauliflower, finely chopped spinach, eggs, Parmesan cheese, almond flour, cumin, smoked paprika, garlic powder, onion powder, salt, and pepper. Mix vigorously with a fork or your hands until a uniform, thick, and slightly sticky dough forms. Let it rest for 5 minutes to allow the almond flour to absorb moisture.

3. Shape the Shells
Preheat your oven to 375°F (190°C). Line two large baking sheets with parchment paper and lightly grease them.
Scoop a heaping 1/3 cup of the mixture onto the prepared sheet. Using the back of a spoon or your fingers, press and spread the mixture into a thin, even circle, about 6 inches in diameter and just under 1/4 inch thick. Aim for uniform thickness to ensure even cooking. Repeat, leaving at least 2 inches between circles. You should get about 8 circles.

4. Bake and Form
Bake for 15-17 minutes, until the edges are golden brown and the centers look set and dry.
Immediately upon removing from the oven, carefully drape each warm, pliable circle over two inverted glass bottles placed on their sides (or over the bars of your oven rack) to create a classic taco shell arch. Alternatively, fold them in half and gently press the bottom to create a stand-up shell. Let them cool and harden in this position for 5-7 minutes.

5. Final Crisp (Optional but Recommended)
For extra-sturdy, crispy shells, once they’ve set in their shape, carefully return them (still on their molds) to the oven for another 5-7 minutes. Watch closely to prevent over-browning. Let cool completely on the molds before carefully removing.

Pro Chef Tips

  • Dryness is Key: Do not skip the step of wringing out the cauliflower. Excess moisture is the enemy of crispness.

  • Uniformity Matters: Take time to spread the mixture evenly. Thick spots will be soft, thin spots may burn.

  • Work Quickly: The shells are only pliable for a minute or two out of the oven. Have your molds ready.

  • Flavor Boost: Add a pinch of chili powder or a tablespoon of chopped fresh cilantro to the dough for extra zest.
