Method
- Heat 2 Tbsp. oil in a large skillet with a fitted lid over medium heat. Add onion and tomatoes; cook 7 to 8 minutes, until the onion is soft and tomatoes are broken down and jammy.
- Add pasta, marinara sauce, water, garlic powder, oregano, salt, and pepper. Increase heat to medium-high and bring mixture to a simmer. Cover and cook, stirring occasionally, until the pasta is al dente, 10 to 12 minutes.
- Remove lid and stir in heavy cream, spinach, and cheese. Stir continuously until spinach wilts and cheese melts, about 2 minutes. Garnish with fresh basil and Parmesan, if using.
