Baked Lemon Spaghetti

We had this tonight. It was light and tasty and a great side for fish or citrusy chicken dishes. Not very cinco de mayo-ish though.

1 package spaghetti (I actually used fusili noodles just to make it more fun)
1/3 cup unsalted butter
1 8 oz. carton sour cream
1 tsp. finely grated lemon peel
3 tb. fresh lemon juice
1/3 cup grated parmesan cheese
salt
pepper

Cook spaghetti until al dente. Drain and place in a casserole dish. Melt butter in medium saucepan over low heat. Remove from heat, and stir in sour cream, lemon peel and lemon juice. Mix until smooth. Pour mixture over noodles in casserole dish and bake at 400 degrees for 15 minutes. Remove from oven, and add parmesan cheese. Seaon with salt and pepper to taste.

PS: I'm taking a break from my nightly dinner meals. I'll just post something if it is new + tasty.
