Tradeoff

- 4
Spaghetti Squash strands come out longer if you run the fork lengthwise along the flesh
- 5
Acorn Squash halves roast beautifully face-down at 400°F for 35 minutes — no peeling needed
- 6
Both freeze well after cooking — portion into bags for quick weeknight sides
- 7
Olive oil, salt, and a little parmesan elevate Spaghetti Squash without adding many calories
- 8
