Begin by preheating the oven to 375 degrees.
Warm a fry pan on medium heat. Add the butter and EVOO and allow the butter to melt and add the onions and saute until translucent. Once translucent, add the garlic and continue to saute until golden brown, being careful not to burn your garlic.
Add the ground beef to a large mixing bowl with the sauteed onions and garlic and the remaining meatloaf ingredients.
Mix until well combined.
Prepare a loaf pan by buttering the pan. Add parchment paper for easy removal of the meatloaf, but cutting the corners for a snug fit.
Add the meatloaf mixture to the loaf pan and be careful to remove any air pockets by firmly adding the mixture to the pan.
Once the meatloaf mixture has been added to the pan, slam the loaf pan a few times to remove remaining air pockets. Using a spatula, smooth out the meatloaf.
If you're feeling fancy, add a design to the top of the meatloaf.
Bake for 1hr at 375 degrees. Once cooked, remove from the oven and loaf pan and allow the meatloaf to set for 10-15 minutes on a meat safe cutting board.
