The Tomato Steam-Roast
Place: Heat olive oil in a deep pan. Place whole tomatoes and the chopped onion in the center.
Steam: Cover with a lid and cook over medium heat until the tomatoes soften.
Peel and Mash
Skin: Once softened, remove the lid and gently peel the skins off the tomatoes with tongs.
Crush: Use a fork or masher to crush the tomatoes directly in the pan, mixing them with the sautéed onions.
Build the Sauce Layer
Aromatics: Stir in the tomato paste and minced garlic. Cook for 2 minutes.
Emulsify: Add the spices, shredded mozzarella, and heavy cream. Stir constantly until the cheese melts and the sauce becomes a smooth, creamy orange-red.
Combine and Simmer
Incorporate: Add the pre-cooked chicken cubes and the cooked pasta into the sauce.
Finish: Toss everything together over low heat for 2–3 minutes to allow the pasta to absorb the flavors.
Garnish
Serve: Top with fresh herbs and serve immediately while the cheese is melty and the sauce is velvety.
