Lightly spray your slow cooker with baking spray. I love using the disposable slow cooker bags, but spraying with cooking spray works too when I don't have the bags on hand!
Browning your roast prior to cooking in the slow cooker is a personal preference. But I HIGHLY recommend it! It gives the roast an amazing texture and flavor!
Warm the olive oil in a deep pot. Once warmed place the roast into the pot. Brown on medium heat for approximately 3-4 minutes on each side. Until lightly browned.
While browning your meat, combine remaining ingredients in a small bowl. Whisk until smooth.
Once you have browned your meat, place it in the slow cooker. Pour the gravy mixture over the top. Cook on high for 2.5-4 hours. I had a 4.06 lb roast and it was perfectly cooked in less than 3 hours.
The gravy that cooks with roast is amazing! No need to do anything extra as it is rich and thick all on its own!
Once your roast is cooked to your preference, ENJOY!
