Dry brining beef tenderloin

I am dry brining(seasoning 24 hours in advance) beef tenderloin. Currently it is wrapped in plastic.

Should it be left uncovered in the fridge or does it matter?

      you can't dry anything that is wrapped in plastic. it needs exposure to air to evaporate moisture. dry it really well after unwrapping. let sit a few days. dry again, then season and let rest at room temp before putting in the oven. after cooking til desired temp, let the meat rest at least 15-20 minutes before cutting.

    2. When I dry brine I leave uncovered 2-3 days

        Ditto. I just did this the week before Christmas for a birthday dinner, and it was the single best beef tenderloin roast that any of us had ever had. I salted it on Thursday morning, put it on a rack in a roasting pan and left it uncovered in the fridge until Saturday afternoon. Roasted at 425 to medium-rare. It was amazing -- great crust and SO much more flavorful than tenderloin usually is (I make tenderloin because the family loves it, not because I think it's an awesome hunk of beef).

          Ditto on the family love. Not my personal fav

            I just did this exact same method of dry brining, but also before roasting I rubbed it all over with olive oil and cracked peppercorns. Came out awesome!

              Ooh, yes, I should have mentioned that before roasting, I brushed the roast with bacon fat (!) and sprinkled cracked pepper all over.

                Just a quick question about this. I have two pieces of tenderloin - one about 6 lbs, the other maybe 3 or 4 lbs. They're in the fridge and salted - cooking them tomorrow for NYE dinner. Timingwise - how long roughly will they take at 425 to medium rare? I have a thermometer but I need a general estimate so that I get them into the oven on time. I assume the larger piece will need a bit more time, but that's fine.

                  i usually blast at 425 for 15 mins then slow cook at 300 for the rest of the time. i figure about 15-20 mins per pound. i usually run it under the broiler at the end.

                  1. re: Nyleve

                    Mine was 5.5 lbs cut in half, so about 3 lbs for one and 2.5 for the other. They took about 50, but may have been closer to rare right in the center at that point (we just saved that part for leftovers). So I'd plan to check your smaller one starting at the 50 minute mark and maybe another 15 - 30 minutes for your larger one. But I would definitely check the larger one when you take the smaller one out, because if it's long and skinny, you may not need as much time as you might think.

                      Great - thanks. This is really helpful. I just needed to know if it was going to be one hour or five. Kidding - I didn't think it would be five, but also didn't want to be serving dinner after midnight.

                      1. re: Nyleve

                        I stuck a probe thermometer in the center of mine (4.5 lbs) and roasted at 425 till it reached 125 degrees. I'm not sure how long it took because I was watching the temperature but it was definitely under an hour. It rested a good 20 minutes while I roasted the brussels sprouts. When I sliced it, it was a perfect medium rare.

                Uncovered - definitely a good method. I would never try and do to a whole tenderloin in that suddenly fashionable "dry brining" method of wrapping in plastic that people are doing with Turkey's for Thanksgiving.

                Aging beef is absolutely tried and true. All the best steakhouses do this. I'll generally age good beef for about 4 days, and usually without any salt, until just before cooking.

                I would stress that it is important regardless of anything else to let your tenderloin warm up to room temperature before you cook it. Then lightly coat with canola oil, kosher salt and fresh ground pepper. This is important to maximizing the amount of yummy medium-rare or rare inside - whichever you prefer.

                Sometimes, I'll slice off some 1.5 - 2" steaks off the tenderloin and do those au poivre in a cast iron skillet, and the rest oven roasted. This makes it very easy to do a pan sauce and a separate gravy, usually with sauteed mushrooms.

                And you already know how important it is to let the meat sit after cooking, so those juices slowly can get back inside the meat fibers. You'll probably need this time anyway ... if only to make a pan sauce.

            2. when brining is done, pat the beef dry, and leave unwrapped in the fridge to continue drying. Wet meat is the antithesis of browning!
              Remember to bring to room temp before roasting:)
