Let's make
Sicilian Casserole, one of my favorite
ground beef recipes. Preheat the oven to 350 degrees F. Bring a large pot of water to boil over high heat. Then place 1 pound of ground beef in another large skillet over medium heat. Start to cook the beef, breaking it up with a fork as it cooks. When the beef starts to render some fat, add 1 chopped onion.
