                In a 6 or 8-quart crock pot, place a large piece of foil into the bottom of the slow cooker, making sure it goes up the sides. Spray the foil with nonstick cooking spray.
              
              
              
                02 - 
                In a large bowl, whisk together the milk, eggs, sugar, 1 packet of the au jus gravy mix, 1 packet of the ranch seasoning mix, and the breadcrumbs until fully mixed.
              
              
              
                03 - 
                Add the ground beef to the bowl. Mix everything together until combined, but don’t overmix to avoid tough meatloaf. Use clean hands for best results.
              
              
              
                04 - 
                Add the meatloaf mixture to the crock pot and gently shape it into an oval.
              
              
              
                05 - 
                In another bowl, whisk together the cold water, peperoncini juice, and the remaining packets of au jus gravy mix and ranch seasoning. Mix until well combined.
              
              
              
                06 - 
                Pour this gravy over the meatloaf and around the sides.
              
              
              
                07 - 
                Place the peperoncini peppers on top of the meatloaf.
              
              
              
                08 - 
                Cook on low for 5-6 hours or high for 3-4 hours. It is done when the internal temperature of the meat reaches 165°F.
              
              
              
                09 - 
                Carefully lift out the meatloaf and place it on a serving dish. Use two spatulas to lift it out, or grab the sides of the foil, though this may be tricky with the gravy.
              
              
              
                10 - 
                Strain the gravy from the crock pot into a medium-sized sauce pot and place over medium heat.
              
              
              
                11 - 
                In a small bowl, whisk together the cornstarch and water until smooth.
              
              
              
                12 - 
                Once the gravy comes to a simmer, slowly pour in the cornstarch slurry while whisking continuously. Allow to simmer for 1 minute until thickened, then turn off the heat.
              
              
              
                13 - 
                Slice and serve the meatloaf, adding the gravy over each portion.
