Mix ground meats, garlic, breadcrumbs, Asiago cheese, parsley, eggs, salt and pepper, and form meatballs (about a golf ball size).
Coat a rimmed baking pan with olive oil, place meatballs on pan. Bake at 400 degrees for 20 minutes. Lower temperature to 375 degrees.
Pour some of your marinara sauce in the bottom of your 13x9 baking dish. Lay cooked meatballs on top of the sauce.
Cover with the rest of your marinara sauce and sprinkle mozzarella cheese over the top. It should be covered in cheese.
Cover dish with foil and bake at 375 degrees for 20 minutes. Remove foil and bake an additional 20 minutes.
The last 5 minutes or so, you can raise the oven temperature back to 400 degrees to help get the cheese golden brown. Alternatively, you could also use your broiler for a few minutes after it's done baking.
