Ingredients:

1 cup milk 2% or higher
2 large eggs well beaten
2 teaspoons granulated sugar
2 (1 ounce) packets au jus gravy mix, divided use (see notes below)
2 (1 ounce) packets ranch seasoning mix, divided use (see notes below)
1 cup panko breadcrumbs (regular bread crumbs can be used_
2 pounds lean ground beef (85/15 or 90/10)
3 cups cold water
¼ cup peperoncini juice (do not use if you don’t tolerate any spice at all)
6 peperoncini peppers (you can use less)
2 Tablespoons cornstarch
2 Tablespoons water

Instructions:

In a 6 or 8-quart crock pot, place a large piece of foil into the bottom of the slow cooker and make sure it goes up the sides and up the sides. Spray the foil with nonstick cooking spray.
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.
To the bowl, add in the ground beef. Mix everything together until combined but don’t over mix. When you mix ground beef too much, it can turn out tough. I find this easiest to combine with clean hands.
Add the meatloaf mixture to the crock pot and gently shape it into an oval.
In another bowl, whisk together the cold water, peperoncini juice, the remaining packets of au jus gravy mix and ranch seasoning. Mix until combined well.
Pour this gravy over the meatloaf and around the sides.
Place the peperoncini peppers on top of the meatloaf.
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.
Carefully lift out the meatloaf and place it on a serving dish. I found the easiest way to do this was to get two spatulas underneath it and lift it out. You could grab the sides of the foil to lift it out but with all the gravy, it would be a bit tricky and messy.
Strain the gravy from the crock pot into a medium-sized sauce pot and place over medium heat.
In a small bowl, whisk together the cornstarch and water until smooth.
Once the gravy comes to a simmer, slowly pour in the cornstarch slurry while whisking the entire time. Allow to simmer for 1 minute until thickened then turn off heat.
Slice and serve the meatloaf, and add the gravy over each portion.
