Over the summer, my parents told us they had been buying rack of lamb at Costco and they enjoyed it more than the lamb chops or leg of lamb. I was surprised because rack of lamb seemed intimidating. When dad needed computer help in July, our payment was rack of lamb dinner. It was so good that when SP saw them on sale at Costco a few weeks ago, he bought a rack for us to make.
We didn't marinate ours, although you could. We simply seasoned the lamb with salt and pepper, seared it in a skillet, and then roasted it in the oven. While the lamb roasted, we made Giada's Basic Polenta. Even though the recipe doesn't call for it, we added some grated parmesan to the polenta.
While the polenta finished and the lamb rested, we roasted some asparagus.
The polenta was the best we've made at home. The lamb was good, too, but next time, we need to give it 22 minutes instead of only 18 in the oven because it was just too pink for me. We did use a meat thermometer, which said the lamb was cooked, but when we sliced it, it was more to SP's liking than mine. I talked to my mom and asked her how long she had given the lamb in the oven and she said 22 minutes. That was perfect for me.
I liked the rack of lamb a lot and it looked impressive. I'd happily make it again. Next time I might marinate the rack in our usual lamb marinade or sprinkle on rosemary with the salt and pepper.
*We followed the cooking instructions on the lamb packaging for roast time/temperature.
