Required Equipment

Baking Sheet

Essential for roasting the cauliflower evenly. Opt for a non-stick sheet or line it with parchment paper for easy cleanup.

Mixing Bowl

A large bowl is needed to toss the cauliflower with oil, protein, and seasonings. A bigger bowl prevents spillage and ensures even coating.

Oven or Air Fryer

While the oven is traditional, an air fryer works beautifully for extra-crispy results with less oil.

Spatula or Tongs

For turning florets midway through roasting to ensure even crispiness.

Ingredients & Substitutions

• 1 large head cauliflower, cut into bite-sized florets – the base of the dish, low-carb and high in fiber.
• 2 tbsp olive oil – promotes crisping and adds healthy fats. Substitute with avocado oil for higher smoke point.
• ¼ cup Parmesan cheese, finely grated – adds protein and flavor. Can substitute with Pecorino Romano.
• 2 tbsp chickpea flour – boosts protein and gives coating for crispiness; almond flour works for keto version.
• 1 scoop unflavored whey protein (optional) – increases protein content without altering taste. Plant-based protein can be used but may slightly change texture.
• 1 tsp garlic powder – flavor enhancer. Fresh minced garlic works if added before serving.
• 1 tsp smoked paprika – adds smoky depth.
• ½ tsp salt – adjust to taste.
• ½ tsp black pepper – adds a subtle kick.
• Optional: red pepper flakes for heat, chopped fresh parsley for garnish.

How to Make High-Protein Crispy Roasted Cauliflower

Step 1: Preheat Oven

Set your oven to 425°F (220°C). High heat is key for crispy edges.

Step 2: Prepare Cauliflower

Wash and dry the florets thoroughly. Moisture is the enemy of crispiness.

Step 3: Mix Coating

In a large bowl, combine Parmesan, chickpea flour, whey protein, garlic powder, paprika, salt, and pepper.

Step 4: Toss Cauliflower

Drizzle olive oil over the florets, then sprinkle the dry mix. Toss until evenly coated.

Step 5: Arrange on Baking Sheet

Place florets in a single layer, ensuring they’re not touching. Crowding leads to steaming.

Step 6: Roast

Bake for 25–30 minutes, flipping halfway. They should be golden and crispy at the edges.

Step 7: Serve

Garnish with parsley or a squeeze of lemon juice. Enjoy hot as a snack or side.

Air Fryer Variation

Cook at 400°F for 15–20 minutes, shaking the basket halfway. Less oil may be required.

Common Mistakes to Avoid

• Overcrowding the pan – causes steaming instead of roasting.
• Skipping the protein flour mix – reduces crispiness and protein content.
• Not drying the cauliflower – moisture prevents crunch.
• Using too low oven temperature – results in soft florets.

---

Pro Tips for Best Results

• Use high-protein coating like Parmesan and chickpea flour for maximum protein boost.
• Flip halfway for even crisping.
• Optional: spray lightly with oil after 20 minutes for extra golden edges.
• Serve immediately or store for later—reheat in oven or air fryer for crispiness.
