Make The Best Cauliflower Pizza Crust tonight: a crispy, cheesy rectangular pizza ready in about 40 minutes.
Preheat the oven to 425°F and line a 15- by 10-inch baking sheet with parchment paper or a silicone baking mat; set it aside so it's primed and waiting. This first small ritual keeps your workflow calm and ensures the cauliflower crust will have a clean, even surface to form on. Lightly spray the lined sheet right before you shape the crust to prevent sticking.
Cut the cauliflower into florets and pulse in a food processor until the texture is very fine — you should have 2–3 cups of cauliflower "rice" with a soft granular texture. Transfer the riced cauliflower to a microwave‑safe bowl, cover loosely, and microwave for 4–5 minutes until just softened; cooling briefly makes the next step easier while preserving moisture that will later be drained.
Using a clean dish towel or cheese cloth, gather the warm cauliflower rice and squeeze it until almost no water remains. This squeezing step is crucial: removing that excess moisture concentrates the cauliflower’s crumbly texture and helps the crust bind and crisp rather than steam in the oven.
Return the drained cauliflower to a large mixing bowl and stir in the two beaten eggs, 1/2 cup shredded mozzarella, 2 tablespoons grated Parmesan, a tablespoon of Italian seasoning, and salt and pepper to taste. Mix until the ingredients form a slightly tacky, malleable mixture — it should hold together when pressed, with visible flecks of cheese and herbs throughout. This combined batter is the true structural base of your cauliflower rectangle.

Spread the cauliflower mixture evenly into a 15- by 10-inch rectangle on the prepared sheet, pressing the surface so edges are compact and the center is uniform in thickness. Lightly spray the top and slide the tray into the preheated oven; bake for 12–15 minutes, watching for a subtle golden-brown surface and firmer, drier edges — the crust should feel set and slightly crisp to the touch.
Remove the baked rectangle and spread 1/2 cup Pomi pizza sauce evenly over the warm crust, sprinkle the combined cup shredded mozzarella and 1/2 cup shredded cheddar over the sauce, and arrange the pepperoni minis across the top. Return to the oven just until the cheeses melt and begin to gloss, about 3–5 minutes; the cheeses should be molten, slightly bubbling, and the pepperoni edges curled and a touch crisp.
Slide the finished cauliflower pizza onto the lined baking sheet and serve right away, scattering fresh basil leaves and a pinch of crushed red pepper flakes if you like heat. Pull a slice to reveal the stretchy mozzarella, the layered cheddar sheen, and the crumbly, golden cauliflower base — best enjoyed hot while the textures are at their peak.
