Mushroom Root Vegetable Pie with Cheddar Rosemary Biscuits

I'm not going to lie. Blogging about local, sustainable foods is not as easy in the winter. Everything seems to be the same color.

Don't get me wrong, I still love root vegetables, winter squash, hearty greens, and fresh baked goods as much as the next guy, but I've found myself glancing through old blog photos, dominated by bright shades of green, red, orange, purple... And to think the first farmers market is still a few months off, it's hard not to be a bit less than enchanted by the offerings of these darker, browner months.

I know eating like this through winter will make the spring harvest that much better, and there is something incredibly satisfying about casserole, soup, and roasted vegetables.

That being said, one of the best things about dishes like this root vegetable and mushroom casserole, adapted from this month's Bon Appetit magazine, is that they make life a little easier after I realized asparagus season is still months away.

Luckily, Portland has been getting good doses of winter sun, and I can still find local supplies, from cheese to apples to mushrooms, at a few local vendors. We'll make it, and maybe I'll be a bit more diligent about freezing and preserving the bumper crops this summer.

Eat well, stay warm, and keep your spirits up!
