Ingredients (Serves 1)

• 200g tofu
• 7cm green onion (about 15g)
• 1/3 onion 
• 1 cup kimchi (about 130 g) 
• 1 Cheongyang chili pepper (or 1 small spicy green chili)
• 1 canned tuna (100 g)
• 3 tbsp cream pasta sauce
• 2/3 cup shredded mozzarella cheese (about 85 g)
• 2 tbsp cooking oil
• A pinch of parsley flakes

For the seasoning

• 1/2 tbsp minced garlic
• 1/2 tbsp sugar
• 1 tsp sesame oil

How to Make

1. Blanch the tofu

Bring a pot of water to a boil and add the tofu. Blanch for 2 minutes, then drain well to remove excess moisture.

2. Prepare the vegetables

Slice the green onion and chili pepper thinly. 

Chop the onion and kimchi into bite-sized pieces.

3. Make the kimchi stir-fry

Heat 2 tbsp of oil in a pan over medium heat. Add green onion, onion, chili pepper, and minced garlic. Stir-fry for 2 minutes. 

Add kimchi, tuna, and sugar. Stir-fry for another 4 minutes, then turn off the heat and drizzle sesame oil. Mix well. 

4. Assemble the gratin

Place the tofu in an oven-safe dish and mash it lightly with a fork. 

Spread the kimchi-tuna mixture evenly over the tofu.

Pour the cream pasta sauce evenly on top. 

5. Air-fry until golden

Top generously with mozzarella cheese. 

Air-fry at 190°C (375°F) for 5 minutes until the cheese melts and turns golden. 

6. Finish and serve

Sprinkle a little parsley on top before serving.
