Butternut Squash and Sage Pasta

Why This Butternut Squash and Sage Pasta Works

In the oven, the butternut squash slowly softens and dries a little on the outside. The edges start to brown, so the cubes taste sweeter and have a bit of chew instead of being mushy. By the time they come out, they are soft enough to break up a bit and cling to the pasta, almost like a chunky sauce.

While the pasta boils, starch from the noodles moves into the water. Later, that starchy pasta water goes into the pan with the squash, butter, and parmesan. As it heats, the starch and cheese thicken the liquid so it turns into a creamy coating that sticks to each strand of fettuccine instead of sliding off.

In the skillet, the butter and sage cook together until the sage leaves dry out and crisp. The butter soaks up some of that sage taste. Garlic softens in the butter too, so it blends into the sauce instead of staying sharp. Pine nuts stay crunchy on top, giving a crisp bite against the soft squash and silky pasta.

Mistakes To Avoid

Cutting the butternut squash in very uneven chunks makes the tray cook unevenly. Smaller pieces burn and turn hard at the edges while big ones stay firm in the center. The final pasta ends up with some squash that’s mushy and some that’s still a bit raw and starchy.

Pulling the squash from the oven too early leaves it soft but not caramelized. Without those browned edges, the pieces stay a little watery and bland, and they break down into a loose mash when tossed with the pasta instead of holding their shape.

Letting the garlic sit too long in the hot butter after the sage comes out often leads to burnt bits. Once the garlic goes past golden, it turns sharp and bitter and those tiny dark flakes spread through the whole pan of pasta.

Dumping all the pasta water in at once instead of adding it gradually makes the sauce thin and soupy. The cheese then clumps or sinks instead of melting smoothly, so the pasta doesn’t get that creamy coating and the squash pieces float around in a watery pool.
