Pesto Butter Pasta with Slow-Simmered Cherry Tomatoes
A quick, satisfying pasta built from leftovers — warm pesto butter coating every strand of angel hair, finished with those sweet slow-simmered cherry tomatoes you keep in the fridge for upgrades like this.
Boil the angel hair in well-salted water. Just before draining, reserve at least 2 cups of the starchy pasta water.
Season and butter the pasta
Add the drained pasta to a bowl and season it with salt and pepper. Toss with the butter and a couple ladles of hot pasta water until the butter melts and coats the strands.
Add the pesto
Add the prepared pesto and keep mixing, loosening with more pasta water — usually 2 to 3 ladles total — until the sauce is glossy and clings to the pasta without being wet or soupy.
Finish with cherry tomatoes
Spoon the slow-simmered cherry tomatoes over the top, letting some of the tomato oil drip into the pasta. Finish with grated cheese.
Notes
This was the perfect little snack — nothing fancy, just a clean bowl of glossy pesto butter pasta with a hit of sweetness from the tomatoes. The pasta water really makes the sauce, so don’t skip it.
