Mushroom Pizza with Cauliflower Crust — Ingredients

  • 3 tablespoons flaxseed
  • 1/2 cup water
  • 1 small head cauliflower
  • 1/3 cup coconut flour
  • 1/2 teaspoon smoked paprika
  • 1/2 teaspoon salt
  • 1 teaspoon dried parsley

Sauce and Toppings

  • 1/3 cup pizza sauce
  • 2 cups mushrooms, sliced
  • 1/4 cup sundried tomatoes, chopped
  • 4 garlic cloves, crushed or minced
  • 1 teaspoon dried basil
  • 1 teaspoon dried oregano
  • 2 tablespoons olive oil

Instructions

  1. Preheat your oven to 450°F (230°C).
  2. Make a flax “egg” by mixing the flaxseed with the water. Let it sit and thicken while you prepare the rest of the recipe.
  3. Remove the cauliflower stem and cut into florets. Pulse in a food processor until it resembles rice. If the cauliflower is wet, wrap the rice in a clean tea towel or cheesecloth and squeeze out as much moisture as possible — this step helps the crust bind and crisp.
  4. In a medium bowl combine the drained cauliflower rice, flax egg, coconut flour, smoked paprika, salt, and dried parsley. Mix thoroughly so the flax egg is evenly distributed and the mixture forms a cohesive dough.
  5. Line a baking sheet or pizza pan with parchment paper. Shape the cauliflower mixture into a round crust, pressing it flat and even with the back of a spoon. Bake for about 20 minutes, or until the crust is golden and set.
  6. While the crust bakes, prepare the sauce by stirring the pizza sauce with the dried basil and oregano. Keep it aside until the crust is ready.
  7. Sauté the toppings: heat the olive oil in a skillet over medium heat. Add the crushed garlic and cook briefly until fragrant, then remove the garlic pieces. Add the sliced mushrooms and cook until they release their moisture and soften. Toss in the sundried tomatoes toward the end to warm through.
  8. When the crust is golden, spread the seasoned pizza sauce over it. Top with the garlic-infused mushrooms and sundried tomatoes.
  9. Return the pizza to the oven and bake for another 8–10 minutes to meld the flavors and warm the toppings.
  10. Remove from the oven, garnish with fresh herbs if desired, and serve. Enjoy!

Tips and Variations

To improve crust texture, make sure you squeeze out as much cauliflower moisture as possible before mixing with the flour and flax egg. If you prefer a different binder, a whisked egg can replace the flaxseed egg for a similar result.

Try adding grated parmesan or a sprinkle of shredded cheese to the crust mixture for extra flavor and browning (if your diet allows). For more robust toppings, roast the mushrooms first to concentrate their flavor, or add cooked bacon, spinach, or thinly sliced bell peppers.

For a crispier crust, bake the shaped crust a few extra minutes before adding sauce and toppings. If the edges brown too quickly, tent the pizza loosely with foil for the final bake.

Storage and Reheating

Store any leftovers in an airtight container in the refrigerator for up to 3–4 days. Reheat slices in a skillet over low heat or in a warm oven (about 350°F / 175°C) until heated through to help maintain texture. Microwaving is convenient but may soften the crust.
