This fast green onion pasta, or scallion pasta, features penne coated in a super creamy cream cheese sauce. It's ready by the time the pasta is cooked.
Cook the pasta: Bring a large pot of water to a boil and salt it generously. Cook the pasta according to the package instructions. While the water comes to a boil and the pasta cooks, prepare the sauce.1 lb pasta
Chop: Trim, wash, and finely slice the green onions. Grate the garlic and finely chop the tomatoes.1 bunch green onions + 3-4 garlic cloves + 4 small tomatoes
Sauce: In a bowl, whisk together the cream cheese, milk, salt, and pepper until smooth.10.5 oz cream cheese + 1 cup milk + ¾ teaspoon fine sea salt + ½ teaspoon ground black pepper
Sauté the vegetables: Heat the olive oil in the saucepan. Cook the green onions, garlic, and tomatoes for 4-5 minutes until the onions have softened. If the pan seems too dry, add a small splash of water halfway through.2 tablespoons olive oil
Add the cream cheese mixture and stir well. Simmer over low heat for 4-5 minutes, stirring often, until the sauce has thickened slightly. Don’t let it come to a boil.
Finish the sauce: Remove the saucepan from the heat and stir in the basil, grated garlic, and Parmesan.
Add pasta: Drain the pasta, reserving a little of the cooking water. Stir 2 tablespoons of the pasta water into the same, then add the pasta to the saucepan and toss well to coat. If the sauce seems too thick, stir in 1-2 more tablespoons of the reserved pasta water or a little more milk.1 small bunch basil + 1 large garlic clove + 1 oz Parmesan
Adjust the seasoning with salt and pepper and serve immediately. Cream cheese sauces are creamiest right after they're made (Note 4).
Notes
Pasta: I used penne, but any short pasta works well
Onions: Green onions are also known as scallions. Spring onions have a thicker bulb, but you can use them in this recipe as well. Use both the white and green parts.
Tomatoes: I used four small ripe tomatoes. Cherry tomatoes are a good substitute; use a generous handful. If you only have regular-sized tomatoes, one large or two medium tomatoes should be enough.
Reheat leftovers gently with a splash of milk or water, as the sauce thickens in the refrigerator.
