Brown each side for 3-5 minutes to develop good crust on the roast before cooking all day.
Toss veggies in the bottom of the crockpot with salt, pepper, 1/2 of ranch packet, 1/2 of au jus packet
Place roast on top and add remaining seasoning
Slap a stick of butter on top & cook in slow cooker on low 7-8 hours
