Ingredients

Servings 6
  • 1 medium zucchini (about 1 cup grated, thoroughly squeezed dry)
  • 1 cup almond flour
  • 1/2 cup grated Parmesan cheese
  • 2 large eggs
  • 1 teaspoon gluten-free baking powder
  • 1/2 teaspoon garlic powder
  • 1/2 teaspoon onion powder
  • 1/4 teaspoon sea salt
  • 1/4 teaspoon freshly ground black pepper
  • 1 tablespoon chopped fresh parsley (optional)

Instructions

  1. Grate the zucchini using a box grater and place it in a clean kitchen towel. Squeeze firmly to remove as much excess moisture as possible to avoid soggy biscuits.
  2. In a large mixing bowl, whisk together the almond flour, grated Parmesan, baking powder, garlic powder, onion powder, salt, and pepper until evenly combined.
  3. Add the eggs and mix thoroughly to form a thick batter.
  4. Fold in the grated and dried zucchini and the chopped parsley if using, ensuring the batter is evenly mixed.
  5. Preheat your air fryer to 350°F (175°C) for 3 minutes.
  6. Line the air fryer basket with perforated parchment paper or lightly grease it to prevent sticking.
  7. Scoop about 3 tablespoons of batter per biscuit onto the basket, shaping them into rounds about 2-3 inches in diameter and 1/2 inch thick. You should get 6 biscuits.
  8. Air fry the biscuits at 350°F (175°C) for 14-15 minutes, flipping halfway through for even browning.
  9. The biscuits should be golden brown and firm to the touch when done.
  10. Remove from the air fryer and let cool for 5 minutes before serving. Enjoy warm as a savory breakfast or snack.

Customize this air fryer zucchini and Parmesan biscuit recipe to suit your dietary needs with these ingredient swaps:

  • Zucchini: Substitute grated yellow squash or finely shredded carrot for similar moisture and texture.

  • Parmesan Cheese: Use Pecorino Romano or nutritional yeast to keep biscuits vegetarian and dairy-free.
  • Eggs: For vegan versions, try flax eggs (1 tbsp flaxseed meal + 3 tbsp water per egg), noting texture may vary.
  • Baking Powder: Use gluten-free baking powder or omit for a denser biscuit.
  • Garlic and Onion Powder: Fresh minced garlic or shallots can replace powders; reduce amount to avoid overpowering.
  • Fresh Parsley: Swap with basil, chives, or omit if unavailable.

These swaps keep your biscuits air-fryer-friendly, low-carb, gluten-free, and family-appropriate, while allowing flexibility.

Air Fryer Model Notes

This low-carb zucchini and Parmesan breakfast biscuits recipe is suited for most air fryer models ideal for quick, healthy snacks. Classified under Snacks and tagged low-carb, keto, gluten-free, and family-friendly, you may need to slightly adjust cooking times and batch sizes depending on your air fryer’s capacity and heat distribution.

Size & Capacity: Small air fryer baskets may require cooking biscuits in batches to maintain crispiness and even cooking. Larger baskets allow cooking all 6 biscuits simultaneously.

Temperature Accuracy: Since the recipe recommends 350°F (175°C) for 15 minutes, monitor your first batch and adjust your air fryer by ±10°F or cooking time by ±2 minutes if needed.

Air Circulation & Basket Type: Perforated baskets help crispiness by allowing airflow. If your basket is solid, use perforated parchment paper to encourage browning and avoid sogginess.

Flip Midway: Turning biscuits halfway through cooking promotes even golden color and texture.

Following these tips ensures perfectly crispy, flavorful breakfast biscuits tailored for your air fryer model.

Crispiness Control

Achieve ideal crispiness with these expert tips tailored for this low-carb zucchini and Parmesan air fryer biscuit recipe:

  • Moisture Control: Thoroughly squeeze grated zucchini to remove excess water, which helps avoid soggy biscuits.
  • Temperature Setting: Air fry at 350°F for balanced browning and tender centers. For a crunchier crust, raise to 360–370°F during the last 2-3 minutes, monitoring closely to prevent burning.
  • Flip Halfway: Turn biscuits midway to brown both sides evenly without drying the interior.
  • Shape Thickness: Maintain about 1/2 inch thickness; thinner biscuits crisp faster but may be drier, thicker yield a tender center with a crisp exterior.
  • Use Perforated Parchment or Light Grease: Enhances airflow and keeps bottoms crisp without sticking.
  • Serving & Storage: Serve warm for peak texture. Reheat leftover biscuits in the air fryer briefly to refresh crispiness instead of microwaving.

These guidelines help you customize crunchiness to perfectly suit your taste while keeping the biscuits moist inside—a perfect low-carb, keto-friendly snack or breakfast.

Reheat your zucchini and Parmesan breakfast biscuits in the air fryer to restore their golden crispiness and tender interior.

Reheating Instructions:

  • Preheat air fryer to 320°F (160°C) for 3 minutes.
  • Arrange leftover biscuits in a single layer, avoiding overcrowding.
  • Heat for 4-6 minutes, flipping halfway through. Start checking at 4 minutes to prevent dryness.
  • Remove and allow to rest for 1 minute before serving.

Tips for Best Results:

  • Let refrigerated biscuits sit 5-10 minutes before reheating for even warming.
  • Add 2-3 minutes if reheating from frozen, flipping midway.
  • Use perforated parchment paper or lightly grease basket to prevent sticking.
  • This heating method preserves their low-carb, keto, and gluten-free characteristics.

This quick reheating approach makes these biscuits ideal for family-friendly meal prep or busy mornings.
