The other day I was out to eat with my family and my mom asked everyone if they could only eat one food for the rest of their lives what would it be?  Both of my cousins and my great aunt had no idea.   My mom, my dad, and I all had an instant answer.   My mom said she would eat Chinese food, specifically some type of chicken dish, my dad said he would eat fried fish, and without another thought I said I’d eat pasta.   When pressed as to what kind of pasta I told everyone I’d eat buttered noodles with garlic and Parmesan cheese.

Penne with Cauliflower and a Brown Butter Mustard Sauce is delicious!

My answer wasn’t too far fetched as when I was in college I often ate pasta every night for dinner.  It was what I liked.   Even now if I’m home by myself or I don’t know what to make I end up making pasta.   It’s easy, it’s delicious, and I love it.   We usually have pasta once a week for dinner and while my husband likes it, I know he’d rather have a variety.  My main pasta dishes include baked penne, spaghetti and meatballs, and eggplant parmesan.   While they are all good, it’s nice to switch it up every once in a while.

Roasted Cauliflower gives a lot of flavor to this delicious penne dish!

I found a recipe that uses roasted cauliflower in a pasta dish.  I’ve used roasted cauliflower in pasta dishes before but never with mustard brown butter.   I know what you are thinking, mustard brown butter?   Yes it sounds a little off but the more I thought about it the more I thought it could work.  Salty and nutty brown butter paired with spicy dijon?   Yep, it could definitely work.

I love an easy but flavorful pasta dish and this Penne with Cauliflower and Brown Butter Mustard Sauce hits the spot!

The dish was fairly easy to make.  Roast the cauliflower, brown the butter, cook the pasta, and put it all together.   The disaster came when I was mixing up the mustard brown butter.  It called for whole grain mustard but I wanted to use dijon.  No big deal, right?  Wrong!   Whisking together the mustard and butter resulted in a broken sauce.   I was a little upset but once I whisked it into the pasta it looked fine.

The pasta turned out really good.   The sauce was rich and slightly spicy from the mustard.  Both the butter and the capers added a bit of saltiness and the roasted cauliflower was packed with flavor!  The breadcrumbs on top were a nice addition and gave the pasta an added texture.  This dish is totally a winner!
