Ingredients

2 Tablespoons extra-virgin olive oil
1 yellow onion, chopped
4 garlic cloves, minced
½ teaspoon dried oregano
2 tomatoes, diced
1 zucchini, diced
1 (6-ounce) can tomato paste
1 ½ teaspoons salt
¼ teaspoon black pepper
12 ounces rotini pasta
3 cups boiling water
3 Tablespoons mascarpone cheese
½ cup fresh basil, chopped

Instructions

In a Dutch oven or large pot, heat olive oil over medium-low heat. Add onions and sauté until translucent, about 5-6 minutes. Add garlic and oregano, and cook for an additional minute.
Add tomatoes, zucchini, tomato paste, salt, and pepper, and stir to combine. Cook for another 4-5 minutes.
Pour boiling water and rotini into the pot. Give it a stir and simmer for 10-12 minutes. You may need to adjust the heat to low if it reaches a rapid boil and starts to splatter. Remove from heat.
Add mascarpone and basil and stir thoroughly. If mixture is too thick, add an additional tablespoon or two of hot water. Garnish with additional basil. Serve immediately.

Notes

Storage: Place in an air-tight container in the refrigerator for up to 4 days.
How to freeze: After completely cooled, transfer to a freezer-safe container and freeze for up to 3 months. To thaw, place in refrigerator overnight.
How to reheat: Place in a saucepan, add 1 tablespoon of water, and reheat over medium-low heat on the stovetop for 8-10 minutes, until heated thoroughly.
Don't skimp on the salt. Although the amount of salt listed (1 ½ teaspoons) may seem like a lot, you aren't adding any salt to the pasta water, so the dish is not overly salty at all.
Adjust sauce to your desired consistency. If the sauce is too thick and you want to thin it out a bit, add hot water one tablespoon at a time until desired consistency is achieved.
