Combine first 4 ingredients; drizzle with 2 teaspoons olive oil. Toss. Arrange mixture on a baking sheet; bake at 400° for 40 minutes or until cauliflower is tender and golden, stirring twice. Cook pasta according to package directions, omitting salt and fat. Drain in a colander over a bowl, reserving 1/2 cup cooking liquid.
Heat a large skillet over medium heat. Add pancetta to pan, and cook for 5 minutes or until crisp, stirring frequently. Remove pancetta; set aside. Add remaining 2 1/2 teaspoons oil to drippings in pan. Add 1/2 cup reserved cooking liquid to drippings in pan; bring to a boil over high heat. Boil 30 seconds or until emulsified, stirring constantly with a whisk. Add rind, juice, thyme, and garlic to pan. Add pasta; toss. Remove from heat. Add cauliflower and pancetta; toss. Top with cheese. Serve immediately.
I *really* wanted to love this recipe. I like the idea of roasting cauliflower, etc. As one review mentioned that they wished it was "saucier", I share the same sentiment. However I did eat it immediately. There wasn't enough cauliflower; so I roasted broccoli to add more. Personally I didn't think the effort was equal to the taste. Perhaps I might use this as a base and make modifications accordingly.
I have lost count of how many times I have made this! I make it for both regular weeknights and when entertaining. Like another reviewer said once the cauliflower has roasted everything comes together quickly, so it does pay to prep. Cheap, easy, very flavorful.
I didn't even make the pasta part of this recipe. I made the cauliflower part and it was incredible. We don't normally eat cauliflower but have been searching for other veggie type sides. This worked well. We only cooked it for 35 minutes and it was very tender. We also put foil on the pan to make cleanup easier.
I made no changes to this recipe, and thought the finished product was good, but perhaps not worth the effort (particularly not on a weeknight). The leftovers were actually even better, though, and if nothing else, the roasted cauliflower was delicious - I'd do that for a quick side anytime.
