Cook a 12 ounce pack of bacon. When it's done, let it sit and drip dry, then crumble and chop it all up.
Dice up a medium sweet onion, and sauté it with about 3 chopped cloves of fresh garlic.
Chop up 1 cup of white mushrooms to add in.
In a large mixing bowl combine 3 pounds of lean ground beef, 3 large eggs, and 2 cups of panko breadcrumbs with your already prepared mushrooms, onion, garlic, and bacon.
Add 2 cups of shredded cheddar cheese and about half of the sauce you hooked up. Finish mixing everything together until blended evenly.
Preheat your skillet in the oven with a little olive oil at 350°.
When your skillet is good and hot, carefully transfer your mixture to the pan and gently form it into a nice round loaf.
Bake covered at 350° for about 40 minutes. Pull your meatloaf out and pour the remaining sauce over the top of it. Bake uncovered for another 20-30 minutes or until everything is nicely browned on top.
As soon as it comes out, top it with a generous sprinkling of more cheese (1 cup).
Let cool for about 10 minutes, then serve and enjoy!
