One of the side dishes I made for Christmas was roasted orange beets in a butter and cream sauce. It was a hit. Just takes a couple minutes once you've got the beets roasted.
Cut a pound or so into 1/2 dice and saute with butter until hot. In a separate pan - or the same pan with the beets removed and covered - boil cream to reduce. A half cup boiled down to a quarter should be sufficient for a pound of beets. Use more cream or reduce less if you want it soupier. Toss the beets and season with salt and pepper to taste.
I also like beets with a yogurt/garlic dressing (mash cloves with salt in a mortar and pestle and mix with yogurt ... goats milk yogurt is great with this). Top it with parsley and chopped toasted walnuts. Beets are great with carmelized onions ... and maybe some arugula for a bitter component.
A little more labor intensive, but beet ravioli are excellent. I believe these, called casunziei, are a Christmas time dish in the Veneto. With a simple butter and poppy-seed sauce and some smoked cheese, incredible. I came across a recipe for this in Michal Negrin's excellent book of regional Italian cooking, Rustico.
