    Pork is one of my favorite go-to proteins for many reasons. The first is obviously because it is delicious. But there are actually many others.

    • Pork is high in protein, thiamine, B6, phosphorus, niacin, potassium, riboflavin and zinc.
    • Many cuts of pork are considered extra-lean sources of protein, with under 200 calories per serving. These include pork loin, pork sirloin, and pork loin.
    • Pork loin has less fat per serving than a skinless chicken breast.
    • Pork sirloin and pork loin meet the American Heart Association’s criteria for a heart-healthy food.
    • Eight cuts meet the USDA guidelines of a “lean” meat. They include the New York and sirloin roasts, ribeye, New York, sirloin and porterhouse chops, 96% lean ground pork, and tenderloin

    Now that we’ve cleared up several pork misconceptions, let’s talk about common cooking mistakes. No food, no matter what it is, tastes good overcooked.

    One of my college roommates swore up and down she hated pork and beef. Turns out, her mother just cooked all meats to a crisp. After I made her my mother’s famous Onion Grilled Pork Chops (at the correct temperature), she quickly changed her mind and has been a meat lover ever since!

    For flavorful and tender pork, there is a misconception that the juices must run clear and all meat is white. Pork should actually be a light blush color and register at an internal temperature of 145 degrees (per the USDA and FDA Food Code).

    Don’t be afraid of using a meat thermometer. There seems to be stigma attached to using one and not being able to magically know the internal temperature of your meat.

    This French Onion Pork Loin uses the already assembled seasoning of onion soup packets. Combined with a small amount of olive oil, it caramelized and makes for a slightly crunchy, sticky, and sweet bark for vegetables and meat.

    PRO TIP: Cut your vegetables into similar sizes, but vary the shapes. This way, they will cook evenly but offer differing textures and visual appeal.

    I’ve used parsnips, carrots, onion and potatoes. Using hearty vegetables that can withstand a long cook time is imperative, as is making sure they are similar sizes so they cook evenly. No one wants a raw potato!

    PRO TIP: Make sure to break up any clumps of onion soup mix to make sure everything gets evenly seasoned.

    It will take you about 5 minutes to get all these items into a roasting pan, about the same amount of time it takes to the preheat the oven. Then, set it and forget it!

    Questions you might have about how to make pork loin:

    Do I have to use a loin? You can use just about any cut of pork you like! I would suggest using a similar weight so you don’t throw off the seasoning to protein ratio. Cooking times will vary based on the size and thickness of the cut you choose.

    Can I substitute the vegetables? Feel free to use whatever veggies you prefer but to keep the seasoning to vegetable ratio correct, try to use a similar amount of hearty vegetables that can withstand 35 minutes in the oven.

    Most pork recipes use salt, why doesn’t yours? Onion soup mix contains salt, so the recipe doesn’t not require any additional salt.

    Different brands contain different amounts of salt. If you think yours needs a little additional, it can always be added at the end.

    What is the difference between a pork tenderloin and pork loin? They both come from the loin, but are shaped different and have different texture profiles.
