Ingredients Equipment Method Notes

Ingredients

  

• 1 large sweet onion
• 1 cup almond flour
• ½ cup grated parmesan cheese
• 2 large eggs
• 1 tsp garlic powder
• 1 tsp smoked paprika
• ½ tsp black pepper
• ½ tsp salt
• 1 tbsp olive oil or melted butter (for brushing)
• Keto-friendly dipping sauce of choice

Equipment

• 1 Sharp Knife
• 1 Mixing bowls
• 1 Whisk
• 1 Baking sheet or air fryer basket
• 1 Parchment Paper
• 1 Basting brush

Method

 

1. Prepare the Onion: Peel the onion and cut it into a “bloom” by slicing downward from the top without cutting through the root. Gently spread the petals apart to form the flower shape.
2. Prepare the Coating: In a bowl whisk the eggs until smooth. In a separate bowl, mix together all of your nut crust ingredients - almond flour, grated Parmesan cheese, garlic powder, smoked paprika, salt, pepper.
3. Coat It in the Onion: Dip the onion in the egg mixture making sure all the petals are covered, then dredge it in the dry mixture. Repeat for better coating.
4. Bake/Air Fry: Line a baking sheet or air fryer basket with the onion. Brush with oil or melted butter. 375°F (190°C) bake 20-25 minutes, or air fry 18 min to golden.
5. Serve: Allow 5 minutes to cool off then enjoy warm with a keto-approved dip.

Notes

• Choose a large, firm onion to ensure the bloom holds shape.
• Freeze onion for 10 minutes before coating to help it stay firm.
• Top with an air fryer if you want it to be crispy with less oil.
• Brush with a little butter or oil for additional flavour.
• Serve immediately for best texture.
