This is by far the best squash I've ever eaten - also the simplest I've ever made. It's slightly modified from Laura Calder's show French Food at Home (see http://www.foodnetwork.ca/recipes/Side/Vegetables/recipe.html?dishID=9137)
Roasted Butternut Squash
1 butternut squash, about 1 pound
1 tablespoon olive oil
Salt and pepper
A few fresh thyme sprigs
A few bay leaves
1 to 2 tablespoons butter
Heat the oven to 400°F/200°C. Wash the squash and slice into 3/8-inch half moons (don't peel it). Toss with the olive oil to coat. Arrange on a baking sheet without overalpping. Season with salt and pepper. Scatter over the thyme and bay. Dot with the butter. Bake 20 minutes or so, turning at half time, until the squash is soft with candied brown edges.
