Season the chuck roast with half of the ranch seasoning mix and cumin on each side.
2.5 - 3 lbs chuck roast, 1 envelope of ranch seasoning, 1 tsp ground cumin
Drizzle olive or vegetable oil into a large pan and place it over medium high heat. Once the oil is nice & hot, put the roast in the pan.
2 tbsp olive or vegetable oil
Sear each side of the roast until golden, then remove from the pan, and set the roast aside.
Toss the vegetables into the same skillet and cook for 5 minutes. Transfer the vegetables to the slow cooker along with the minced garlic.
2 medium sized yellow onion, 3 stalks of celery, 12 oz baby carrots, 5 cloves fresh garlic
In the same skillet, add the beef broth to deglaze the pan, and adjust the heat from medium high to high. Bring to a boil, then turn off the heat.
3 cups beef broth
Pour the beef broth over the vegetables in the slow cooker. Add the roast, the rest of the ranch seasoning, and a packet of gravy mix.
1 envelope of brown gravy mix
Place the butter on top of the roast, then add in the pepperoncini peppers.
5 tbsp unsalted butter, 8-10 pepperoncini peppers
Set the slow cooker on high and let cook for 8 hours. After 8 hours, the roast should be tender enough to easily fall apart using tongs or a fork.
Serve & enjoy over mashed potatoes or rice!
