Preheat oven to 350°F. Spray a 2-quart baking dish with nonstick spray. Set aside.
Brown the ground beef and garlic in a medium skillet set over medium-high heat. Crumble as you brown. About halfway through, add in the onion and stir to combine. When the beef is fully cooked and the onion is translucent and fragrant, drain of any excess oil and set aside.
