I love rutabagas. In fact they are one of my favorite veggies of all time!
I wasn't sure what the calorie count was compared to other root veggies so I was surprised how relatively low cal they are. According to Calorieking.com, here are the calorie counts for 4 oz of each (boiled, no butter or milk added):
Yam 132 calories
Potato 106 calories
Sweet Potato 86 calories
Rutabaga 44 calories
I like rutabagas mashed with salt, pepper and a pat or butter or Smart Balance Spread. Yum!
If you are not familiar with rutabagas (in England they are called Swedes - go figure! ) here is how to cook them. Cut off ends and peel. Cut into 1" cubes - careful - they are quite hard to cut so you need a sturdy cutting board and sharp knife. I like to cut them in half first and put them flat side down to get a safe grip.
Cover them with water in a large pan and add a teaspoon of salt. Boil till soft - about 20 minutes. Drain well (or they will be watery) and mash with pepper, salt and a pat of butter or light margarine. I use an imersion blender to mash them so that they aren't too lumpy as it seems to work better than a potato masher. I could just eat a big bowl right now!
