Ingredients
- 2 tablespoons olive oil

- 1 stick butter, cut into cubes
- 3 tablespoons cornstarch
Instructions
Note: See notes for Oven and Instant Pot methods.
Crock Pot Method:
- Heat the olive oil in a large skillet, preferably cast iron, over medium-high heat. Sear the roast for 3 minutes on each side until browned. Transfer the roast to the Crock Pot.
- Sprinkle the Ranch seasoning mix and Au Jus mix evenly over the roast.
- Top the roast with cubed butter and pepperoncini peppers. Add optional vegetables like carrots or baby red potatoes if desired.
- Cover and cook on low for 8-10 hours or on high for 5-6 hours, until the roast is fork-tender.
- Once done, transfer the roast to a plate and cover it with foil to keep warm. Leave the juices in the Crock Pot.
- Turn the Crock Pot to high and proceed to make the gravy.
Make the Gravy:
- In a small bowl, whisk together 3 tablespoons of cornstarch with 3 tablespoons of cold water until smooth.
- Bring the meat juices in the Crock Pot to a boil. Slowly pour the cornstarch mixture into the boiling liquid while stirring continuously.
- Reduce the heat to a simmer and continue stirring until the gravy reaches your desired thickness.
- Transfer the gravy to a serving container and serve alongside the roast.

Tips
- Searing is Key: Browning the roast before slow cooking locks in flavor and enhances the overall taste.

- Custom Vegetables: Add carrots, potatoes, or onions directly into the Crock Pot for a complete one-pot meal.
Variations and Substitutions
- Spice Level: Add extra pepperoncini peppers or a splash of the brine for more heat.
- Dairy-Free: Use dairy-free butter alternatives for a dairy-free version.
- Low-Sodium: Opt for low-sodium Ranch and Au Jus mixes to reduce the salt content.
