 Slow Cooker Red Wine Striploin Roast Beef

I’ve partnered with Sterling Silver®  Premium Meats to cook up three delicious recipes with their premium beef products and this is recipe number 2!  You should definitely check out the amazing Herb & Garlic Stuffed Prime Rib   I made at Christmas using their prime rib. That was the best prime rib roast that we have ever made! Sterling Silver Meats are known for their exceptional quality and because of their superior processes, the quality of Sterling beef grades 2 to 10 percent higher than both U.S. and Canadian average quality grades.If you are going to spend money on an excellent striploin roast you should make it the best quality of beef that you can buy.

Striploin roast might not be a cut of roast that you are accustomed to seeing on your local grocery store shelves. When you are looking at a striploin roast it can also occasionally be called a “top loin roast”. This is not to be confused with top sirloin!  The striploin cut is a leaner roast from the same area as the rib roast, making it second only to the prime rib in quality and tenderness.

To order a Sterling striploin roast like the one I used in this recipe, you can use the website locator to find a retailer.  Here in Alberta, it’s Safeway and Sobey’s that regularly carry Sterling Silver Premium Meats. I simply phoned my local Sobey’s and ordered the roast that you see in the photos and it was ready by noon! Remember that you can call and order your roast or steaks to be cut how you like them, the butcher is more than happy to oblige!

For this striploin roast beef I wanted to see if I could get the best of all worlds. I wanted to see if I could cook it in the slow cooker for a few hours, infusing the roast and my vegetables with slight red wine flavour and extra moisture, then seal it all inside the roast with a flash broil at the end. The flash broil at the end is a relatively new concept and has been applied to prime rib recipes as well lately. It’s usually thought that you should always sear in the juices right at the start of roasting, however there is a new line of thinking that employs the opposite method.

This worked like a charm. I was naturally apprehensive at the thought of cooking a prime cut of beef in the slow cooker as traditional thinking is that the slow cooker should be reserved for only cuts of meat that need breaking down for hours with low and slow cooking. I thought that there is no reason a premium roast like ones from Sterling Silver Premium Meats wouldn’t be exceptional if done correctly in the slow cooker as well.

I like that this recipe takes 2-3 hours of low and slow cooking which a person can fit into their schedule as needed. I cooked it to just medium-rare at 125 °F, then flash broiled it and tented it in tinfoil. Most of my family enjoys roasts done medium, just nicely pink in the center. Thanks to the low and slow cooking, this striploin roast was butter tender on the inside and crisp on the outside.

Take a look at that outer crust! Thanks to the 5 minutes broil of that butter herb paste on top you get a buttery, cripsy crust, which is my favourite part of the roast, to be honest.

Striploin Roast Internal Temperatures

Measure the roast with a proper meat thermometer in the middle of the roast for an accurate temperature reading.

  • Blue in the middle– 110 °F – when the middle of the roast still “quivers”
  • Rare- 120-125 °F
  • Medium-rare– 125- 135 °F i
  • Medium – 135- 140 °F
  • Medium Well-140- 150 °F
  • Well-done– 155 + °F

This roast was done to 140 °F in the middle when I was finished tenting it, I used my Thermapen for an exact measurement to show you guys what 140 °F looks like – and what it looks like is one amazing dinner! 

Slow Cooker Red Wine Striploin Roast Beef Tips & Tricks

  • As this isn’t an all day slow cooker roast beef, make sure to chop your vegetables smaller than you usually would. They need to cook in the 2-3 hours in the slow cooker. I find that half inch pieces are perfect for potatoes and carrots.
  • Make sure to sear the outside of the roast before you place it in the slow cooker for extra flavour.
  • Place the striploin roast beef on top of the onions as stated in the recipe to give it a barrier between the roast and the crock pot liner. It simply helps distribute the heat better throughout the recipe contents.
  •  The sear at the end really makes this roast what it is! Slather on that herb butter paste and sear the flavour, making a perfect crust on the outside of the roast.

Happy cooking!

  • 1 3-4 lb Sterling Silver Premium Meats Striploin Roast beef
  • 1 tbsp olive oil
  • 1 large white onion
  • 3-4 large russet potatoes cubed into small pieces
  • 2 large stalks of celery
  • 2-3 large carrots sliced THIN
  • 1 cup sliced white mushrooms
Red Wine Sauce
  • 1/2 cup red wine - Merlot works well
  • 2 cups strong beef broth ( use 1 1/2 cubes for 2 cups water)
  • 1 tbsp minced garlic
  • 1 tbsp freeze dried thyme
  • 1 tbsp Worchestershire
  • 3 tbsp tomato paste
  • 1 tsp dried rosemary, crushed
Salted Butter Herb Crust
  • 1/4 cup butter
  • 1/2 tbsp garlic paste or minced garlic (use 1 tbsp if you love garlic)
  • 1 tsp thyme
  • 1/2 tsp black pepper
  • 2 tbsp sea salt flakes
  1. If you would like to cook larger vegetables, skip the first two steps and leave your roast in the fridge. Simple start cooking the vegetables in the red wine sauce 2 hours earlier, then add the seared roast in later. 

  2. Heat the olive oil in a large skillet over medium heat. Place the striploin roast in the skillet and sear the roast on all sides, until browned.

  3. Place the onions in the bottom of the crockpot, then add the roast on top of them in the crockpot fat side up. Place all of the remaining assorted vegetables around the roast. 

  4. Whisk together the red wine sauce. Pour over the roast and vegetables. 

  5. Cook the roast on low for 2 1/2- 3 hours. When the roast reaches an internal temperature of 120, pre-heat your oven to broil.

  6. Combine the Salted Herb Butter Crust ingredients together. Remove the roast from the crockpot using two forks or tongs and place on a baking sheet. Slather the butter mixture on top of the roast.

  7. Place the roast in the oven and broil for 5-8 minutes until the outside of the roast has become crispy and browned. Remove and tent with foil for 10 minutes while you prepare the gravy.

  8. To make the gravy, take the red wine broth from the crockpot and place in a sauce pan. Whisk 2 tbsp of cornstarch in with 1/3 cup of water. Bring the red wine sauce to a boil. Whisk in as much cornstarch slurry as needed until the sauce thickens. 

  9. Slice the roast and serve with the vegetables and gravy.

Recipe Notes

IF you would like to cook larger vegetables, simply start the vegetables in the red wine sauce two hours ahead of the roast. You can then nestle the striploin roast into the vegetables in the crockpot and continue cooking for another 2-3 hours, or until your desired roast internal temperature is reached.

    This was very good. I cooked this in my cast iron casserole pot in the oven. So tasty!

  2. You talk about onions in the preamble but there is no mention of onions in the actual recipe or the recipe instructions.
