Step 1

If making tzatziki, make it first so it has time to chill. If baking, preheat oven to 400 degrees F.

Step 2

Grate the onion on the largest holes of the grater straight into a large bowl (we want all the juices!), then whisk in the eggs. Add the remaining Meatball ingredients up to the beef/lamb and mix well. Add the beef and lamb and mix with your hands just to combine (don’t over-mix or your meatballs will be tough).

Step 3

Line a baking sheet with foil (even if cooking the meatballs on the stove for easy cleanup) and lightly spray with cooking spray. Scoop the meat mixture using a 1 ½ tablespoon cookie dough scoop (or a heaping 1 tablespoon), then gently roll them a couple times in between the palms of your hands, but don't compact too much or the meatballs will be dense. Place the meatballs onto the prepared baking sheet without touching.

Step 4

Generously spray the meatballs on the baking sheet with cooking spray OR for the ultimate crazy tender meatballs, drizzle them with 3-4 tablespoons melted butter mixed with 1 tablespoon lemon juice (AMAZING!).

Step 5

Transfer the baking sheet to the oven and bake at 400 degrees F for 20-25 minutes, or until the meatballs are cooked through (reach 160 degrees F).

Step 6

Add enough olive oil to a large nonstick skillet (my favorite pan!) to lightly cover the surface of the skillet. Heat over medium heat (medium-low if your skillet runs hot).

Step 7

Working in batches, add the meatballs to the skillet in a single layer without touching and cook until nicely browned all over and cooked through (160 degrees F), about 5 - 6 minutes. Remove to a paper towel lined plate and tent with foil to keep warm. Repeat with remaining meatballs.
