On your next Italian night, upgrade the pasta -- whole wheat adds extra fiber without extra effort. Pair it with veggies and a creamy sauce for a dinner kids will devour.
In a large pot of boiling salted water, cook pasta according to package instructions. Reserve 1 cup pasta water; drain pasta.
In pot, melt butter over medium-high. Add onion and cook until translucent, 6 minutes. Add flour and whisk to combine. Whisk in milk and cook, whisking frequently, until simmering and thickened, 10 minutes. Season with salt and pepper. Add zucchini and cook until crisp-tender, 6 to 8 minutes. Stir in pasta, tomatoes, Parmesan, and basil, adding enough pasta water to create a thin sauce that coats pasta. Serve with more Parmesan, if desired.
