Preparations

Cook the pasta:
In a large pot with boiling salted water, cook the rotini according to package directions until al dente. Drain and set aside.

Prepare the sauce:
In a large skillet, heat olive oil over medium. Add garlic and sauté for about 1 minute until fragrant, without burning.

Add the crushed tomato, salt, and pepper. Simmer for 8–10 minutes to concentrate flavors.

Mix in the pasta:
Add the cooked pasta to the skillet and stir to coat with sauce.

Add the mozzarella:
Fold in mozzarella cubes and cook for another 1–2 minutes, just until they start to melt.

Serve and garnish:
Plate the pasta, sprinkle with grated parmesan, and garnish with fresh basil.
