Original recipe called for 400 - I think, like the one reviewer mentioned - may be too high. Maybe 375? Another thought is to maybe add the leeks a little into the cookiing -- the squash is definatly going to take longer to cook. Just some tweaking going on here. thanks for looking, and cooking!
In a large bowl, mix the squash, leeks, herb, salt, pepper, olive oil and pecans (if your are using them) together.
Place on a cookie sheet (may take 2) and cook for appx 1/2 hour.
This is some really good stuff!
Cook time is 1/2 hour, prep time is going to vary - the squash does take time, but well worth it.
Edit to add that after peeling, seeding and halving/quartering the squash, put it in the microwave for 2 to 3 minutes. This will help with dicing of the squash and help even out the cooking time with the leeks.
