Step 1

Preheat oven to 400 degrees and line a rimmed baking sheet with parchment paper or spray with non-stick baking spray.

Step 2

Whisk together liquid mixture ingredients in a liquid measuring cup.

Step 3

(To grind your own beef, see instructions below.)To use pre-ground beef:Combine all ground beef mixture ingredients in large bowl and mix gently until partially combined. ( I use my stand mixer with the flat beater on stir speed.) Then add your liquid ingredients and mix again until just fully combined. Don't overmix.

Step 4

Lay beef pieces out on parchment lined tray that will fit in your freezer. Freeze for 20 minutes. I used the KitchenAid Food Grinder Attachment with the finer grinding plate. I set my mixer to speed Add pieces of beef one at a time to grinder, alternating with bread, onion, Parmesan, parsley and garlic.

Step 5

Place your ground beef mixture in your stand mixer bowl and attach the flat beater. Add your liquid ingredients to the bowl. Mix on stir speed until just combined. Let mixture rest for 5 minutes, so the bread particles can absorb the liquid. Mix again just for a few turns.

Step 6

Portion and roll your meatballs. I use a 1/4 cup or 2-ounce scoop for mine.

Step 7

Place on prepared baking sheet, leaving 2" between them. Bake for 15-20 minutes or until cooked through. If I am transferring them to a pot of marinara sauce, I will only cook them until they are browned on the outside as they will cook the rest of the way in the sauce.
