Wet Aged Sirloin Tip Roast
The process of wet aging grass-fed meat turns moderate cuts into prime tender cuts. The trick to the success is planning in advance, giving enough time for the wet aging to work it’s magic. (Note: If the roast has been pre-wet aged, it will be noted on package and that step listed below can be eliminated.) 
Ingredients:
1 – 3 pound Sirloin Tip Roast
2 – tablespoons olive oil
½ – teaspoons garlic powder
1 – teaspoon onion powder
1 – tablespoon thyme leaves
2 – teaspoons sea salt
1 – tablespoon black pepper
1 - cup buffalo stock/broth or organic beef stock/broth
½ - cup red wine
2 – tablespoons butter
Preparation:
- If roast has not been wet aged, place the frozen roast in it’s packaging on a plate and place in the back of your refrigerator. Allow roast to wet age for two weeks, turning roast over every 3 days.
- Remove wet aged roast from the package in a clean sink and rinse under cold water. Pat dry with paper towels, and place on a platter.
- Mix olive oil and seasonings together in your roasting pan. Add the roast and rub the seasonings into the roast. Cover and let roast rest at room temperature for two hours before cooking.
Cooking Options:
Method One – Hot & High, then Low & Slow- Preheat oven to 500°.
- Place roast in a heavy roasting pan and place in the oven for 13 minutes (or about 4.5 minutes per pound). Reduce the heat to 475°.
- After 13 minutes, shut the oven off and leave the roast in the oven for two hours. DO NOT OPEN THE DOOR.
- Remove the roast from oven and place on a cutting board or platter. Slice the roast thin on the bias, keeping slices tightly together. *Optional for re-heating: Transfer the sliced roast onto a baking sheet and place in a 500°pre- oven for 5 to 7 minutes.
- Place the roasting pan with the juices on stove-top over medium high heat. Stir in stock and wine scraping up the bits for the bottom of the pan. Bring to a boil, then reduce heat to medium and allow au jus to reduce to about 1 cup. Whisk in butter and season to taste.
- Serve the sliced roast with hot au jus.
Method Two: Low & Slow
- Pre-heat oven to 210°.
- Place roast in a heavy roasting pan and place in pre-heated oven. Roast at 210° for 1 hour. Reduce heat to 190° and continue to roast for 5 hours.
- Remove roast from oven and place on a cutting board or platter, cover with foil and allow the roast to rest for about 10 minutes.
- While the roast is resting place roasting pan on stove-top over medium high heat. Stir in stock and wine scraping up the bits for the bottom of the pan. Bring to a boil, then reduce heat to medium and allow au jus to reduce to about 1 cup. Whisk in butter and season to taste.
- While au jus is reducing, slice roast thin on the bias. Serve and pass with au jus.
Method Three: Sear & Indirect Heat for Gas or Char Grill
- Heat char grill or get coals in grill very hot, 500° +.
- Place roast on top of the hottest part of the grill and sear the roast for 3 minutes. Turn the roast two additional times searing each un-grilled side for 3 additional minutes.
- If using a gas grill turn the left and the right burners to low, keeping the roast in between and away from the heat sources. Insert a meat thermometer into the center of the roast, and close the grill lid. Continue to roast for one hour or until meat thermometer registers 135°, for medium rare. If using a char grill, push coals around to one side. Place the roast on opposite side of heat, and cover with the grill lid. Continue to roast for one hour or until meat thermometer registers 135° for medium rare, rotating once during the cooking time.
- Remove roast from the grill and transfer to platter and slice thin on the bias.

i am allergic to wine… what do i use instead or should i just leave it out all together
Jill / Wild Idea Buffalo Co.
Hi Miquel. I would substitute the wine with more stock or broth. It should be just fine.

Hi Jill! I want to make this for Christmas dinner this year! How many people do yo think this will feed? 8-10? Todd

Todd, the common rule is 1/4 pound of meat per person. But keep in mind, that is the size of a quarter pounder at McDonalds. Some people will eat a small amount. HOWEVER.. I find that I like to plan for 1/2 pound per person. A good roast never goes to waste, next day left overs are so yummy. Think beef and noodles etc. I like to have too much vs not enough. but that is just me.

We’ve wet aged twice and it was delicious. I wouldn’t do it with grocery store meat as I don’t trust how long they had it thawed.
Michelle
I am excited/nervous to try this roast using the wet-aging process! I’m trusting everyone’s reviews that it’s great. Which of your two methods of ccoking this do you think is better? Also, I put the roast in the refrigerator for 2 weeks prior to the date I wanted to cook it. Now our plans have changed, and it seems I will have to push this dinner back a day or two. So, it will have been in the refrigerator for 15 or 16 days. Will this be okay?? Or is this too long? Thanks for the help!

HI Michelle – Sorry to get this late. I sent you a direct message. In short – roast should be just fine.
I left my contact info in email – so call if you would like. jill

I am wet aging a sirloin tip roast for Christmas dinner. What internal temperature would you recommend? Beef for rare is usually 120 degs F resting to 125 degs F. Also any recommendations for smoking a sirloin roast. I’ve smoked a bison tenderloin a couple of times to 120 resting to 125 and it turned out fantastic. If I smoke it should I do the same as for the tenderloin?
Jill
Hi Gregory. For internal roast temperature for medium rare, I recommend it be 135 to 140 degrees. So, pull out when it is 5 degrees less than your desired temperature. I would also use the method above. Thank you for your order and support! Wishing you a delicious holiday! jill

Can I still cook with this method if I don’t have time to wet age?
Jill
Alison – Yes, you sure can. Enjoy and thank you! jill

OK, going for it! Roast is in the fridge, will report back in two weeks!
Howard
Did the roast this past Saturday, came out very good. Have to shorten cooking time a bit for the next one, it was a bit overcooked but still tender and delish. We have a more commercial oven, it really holds the heat. Amazing that the meat was still tender, can’t wait to try it again.
Nancy Spoolman
I am going to use Method 2 – Slow Roast. Do you cover it at all so it won’t dry out? I’ve waited for a while to do this roast. I cannot wait to try it!

I was really skeptical to follow this. For one, I’m reluctant to leave meat thawing in refrigerator for that long, and two, how in the world will this come out cooked after only 12 mins under heat? So I only wet-aged for a week, and I upped the cooking time to 15 mins. (Used first method listed) It turned out amazing, but slightly over cooked. Next time I will trust the recipe and follow exactly, I’m sure it will be even better. I made mashed potatoes and honey glazed carrots for side dishes. Thank you guys for this awesome recipe!
