Preheat the air fryer: Set it to 400°F (200°C). Lightly oil the basket or line it with parchment designed for air fryers.
Season the gnocchi: In a bowl, toss gnocchi with olive oil, garlic powder, onion powder, Italian seasoning, salt, and pepper.
Make sure every piece is well coated.
Air-fry until golden: Arrange gnocchi in a single layer. Cook for 10–12 minutes, shaking the basket halfway, until edges are crisp and lightly browned. Thicker gnocchi may need an extra 2 minutes.
Start the sauce: While the gnocchi cook, melt butter in a skillet over medium heat.
Add minced garlic and red pepper flakes. Cook 30–60 seconds until fragrant, not browned.
Add tomatoes: Pour in passata or crushed tomatoes. Simmer for 3–4 minutes to slightly reduce and sweeten.
Make it pink: Lower heat.
Stir in heavy cream and simmer gently for 2 minutes. The sauce should turn a warm pink color. Season with a pinch of salt and pepper.
Cheese it up: Stir in parmesan until melted and smooth.
If the sauce is too thick, add a splash of water or cream. Taste and adjust salt.
Toss and finish: Add the crispy gnocchi straight from the air fryer into the skillet. Toss to coat.
Cook 1 minute to marry the flavors.
Brighten and serve: Add chopped basil or parsley. For extra lift, finish with a little lemon zest or a quick squeeze of lemon. Serve hot with more parmesan on top.
