Ingredients

2 cups pasta (penne, fusilli, or spaghetti)

2 large onions (thinly sliced)

2 tbsp olive oil or butter

3 cloves garlic (minced)

1/2 cup cream or milk

1/2 cup grated Parmesan cheese

1/2 tsp salt (adjust to taste)

1/2 tsp black pepper

1 tsp sugar (helps caramelization)

1 tsp Italian seasoning

1/2 tsp chili flakes (optional)

1/2 cup pasta water (reserved)

Instructions

Cook the Pasta

Boil pasta in salted water until al dente.

Reserve 1/2 cup pasta water, then drain and set aside.

Caramelize Onions (Air Fryer Method)

Place sliced onions in an air fryer-safe dish

Add olive oil/butter, sugar, and a pinch of salt

Air fry at 160°C (320°F) for 12–15 minutes

Stir every 4–5 minutes until onions turn golden brown and sweet.

Add Garlic & Flavor

Add minced garlic and air fry for 2 more minutes until fragrant.

Make the Sauce

Mix into the caramelized onions:

cream or milk

Parmesan cheese

black pepper

Italian seasoning

chili flakes (optional)

Stir until creamy and smooth.

Combine Pasta

Add cooked pasta and a splash of reserved pasta water.
Mix well so everything is coated in the rich onion sauce.

Final Air Fry

Transfer to a baking dish and air fry at 180°C (350°F) for 8–10 minutes until:

top is slightly golden

sauce is bubbling

edges are lightly crispy

Serving

Serve hot with extra Parmesan on top and fresh parsley if available.

Tips for Best Flavor

Slow caramelization = deeper sweet flavor

Add a pinch of balsamic vinegar for gourmet taste

Mix mozzarella with Parmesan for extra creaminess

Don’t skip pasta water—it makes the sauce silky
