    Cast Iron Pork Tenderloin

    Published: Nov 15, 2011 · Modified: Apr 20, 2022 by thekitchenprep · This post may contain affiliate links ·

    How was your weekend? {Yes, I realize it's already Tuesday. Running a day late here!} Ours was great. We were actually in town all weekend long for the first time in heaven knows how long, so naturally, we did what any young, exciting couple would do: Nothing. 😛

    Ok, not nothing, nothing. We did do some stuff. Like make homemade French bread pizzas, drink wine, and watch free movies On Demand. We checked out a local craft show, stocked up on home essentials {read: about a zillion rolls of toilet paper} at Costco, and watched a LOT of football. Well, one of us did, anyway. And I attended my dear friend's second baby shower on Saturday. If you are under the age of about 28 or so, that may seem like a snooze of a weekend to you... but to us... it was just what the doctor ordered. {I know, I know. But trust me, you'll understand one day.}

    Last week was an interesting one for me. The universe decided to throw me a few curveballs and I am just doing my best to adjust to the changes {which, if you know me at all, you know is not always super easy for a control freak  person like myself.} Regardless, I'm rolling with the punches and heeding my little sister's advice: "Keep calm and stuff your face with pumpkin bread." {A recipe I shall share with you soon!} Is it any wonder that we're related? 😉

    Meanwhile, the hubs and I are attempting a money-saving month, doing what we can to save our pennies. What does that mean? Well... No dining out {Which isn't too difficult since we usually only go out to eat once a week anyway}. No drinks and outings with friends. And no unnecessary spending {like visits to the frozen yogurt shop up the road that we are obsessed with}. That leaves us with resourceful meals at home and finding ways to entertain ourselves as inexpensively as possible. {Hence all the football watching.}

    When we threw our Oktoberfest party a few weeks ago, we bought 2 large packages of pork tenderloin from Costco, half of which was prepared and inhaled promptly the day of the party. The other half was put away to use for a mid-week dinner. While I thought I'd try something new with the remainder, I ended up using the exact same recipe that I used for the party at the husband's request because he enjoyed it so much. This Mustard Marinated Pork Tenderloin received rave reviews at the party, too {and I never got to try it}, so I figured there was no harm in making it again.

    If you're looking for an easy, mid-week meal with tons of flavor that you can pair with a variety of sides, this recipe is for you. Whisk the marinade together, throw in the tenderloin, refrigerate overnight & forget it until you're ready to cook. The result?

    A scrumptious dinner & a happy husband! {And wife.}

    Give it a try!

    Mustard Marinated Pork Tenderloin

    Trim the pork tenderloin if necessary. In shallow bowl, combine olive oil, mustard, grainy mustard, lemon juice, garlic, salt, pepper, and oregano and mix well. Add tenderloin and turn to coat.
