Can I make Air Fryer Savory Cheddar and Spinach Biscotti ahead of time?

You can prep the ingredients and seasoning ahead, but air fry close to serving for the best texture.

How do I keep this recipe from turning soggy?

Cook in a single layer, leave space for airflow, and avoid adding too much oil or sauce before the food has crisped.

Can I adjust the seasoning?

Yes. Keep the same cooking method and adjust salt, spice, herbs, citrus, or sauce to match your taste.

How do I know the gluten-free all-purpose flour blend is done?

Use the visual cues in the instructions first: the outside should be browned or crisp and the center should be hot and tender. For meat or seafood, confirm doneness with a food thermometer.

1/4 teaspoon smoked paprika
1 large egg

Ingredients for Air Fryer Savory Cheddar and Spinach Biscotti

Instructions

Preheat your air fryer to 320°F (160°C). Lightly grease the air fryer basket or line with perforated parchment paper designed for air fryers.
In a medium bowl, whisk together the gluten-free flour, baking powder, salt, black pepper, garlic powder, and smoked paprika until well combined.
In a separate small bowl, beat the egg with olive oil and milk until thoroughly mixed.
Pour the wet ingredients into the dry mixture. Stir gently to combine using a spatula.
Fold in the shredded cheddar cheese, finely chopped spinach, parsley, and lemon zest until evenly incorporated. The dough will be slightly sticky but manageable.
Lightly dust your hands with gluten-free flour and shape the dough into a log approximately 8 inches long and 2 inches wide, placing it directly on the prepared air fryer basket or parchment.
Air fry the biscotti log at 320°F (160°C) for 15 minutes, until the exterior is firm and lightly golden.
Remove the basket and carefully transfer the baked log onto a cutting board. Using a serrated knife, slice the log diagonally into 1/2-inch thick biscotti pieces.
Arrange the biscotti slices cut-side down in a single layer back into the air fryer basket, ensuring they do not overlap.
Continue air frying at 320°F (160°C) for 5-7 minutes on the first side until crisp and golden.
Flip each biscotti slice and air fry for an additional 5 minutes, until both sides are evenly crisp and toasted.
Remove the biscotti from the air fryer and allow them to cool completely on a wire rack before serving. The biscotti will become crunchier as they cool.
Store cooled biscotti in an airtight container at room temperature for up to 4 days, or freeze for extended freshness.

Tips

Air Fryer Model Notes

Cook Air Fryer Savory Cheddar and Spinach Biscotti in a single layer when possible. Basket models may need batches; oven-style models may need a tray rotation halfway through for even browning.

Crispiness Control

Pat the gluten-free all-purpose flour blend dry, avoid crowding, and use only a light coat of oil or sauce before cooking. Add wet sauces near the end when you want the outside to stay crisp.

Doneness Cues

Look for browned edges, a hot center, and the texture described in the instructions.

Reheat In The Air Fryer

Reheat leftovers at 325 F to 350 F in a single layer until hot and crisp again. Add fresh herbs, citrus, or sauce after reheating.

Spinach: Swap in kale or Swiss chard to vary leafy greens while keeping the savory, nutrient-rich profile.
Olive Oil: Use avocado or neutral oils to retain healthy fats and savory notes.

Reheat in the air fryer at 325 F to 350 F in a single layer until hot and crisp again. Add fresh herbs, citrus, or sauce after reheating for the best flavor.
