Directions
Place a large skillet over medium heat.
Once hot, add the ground sirloin, minced garlic, Worcestershire sauce, salt, pepper, and onion powder. Use a spatula to break up the meat and cook until it is completely browned, approximately 7 minutes.
Stir the beef stock and ketchup into the browned meat.
Add the drained tomatoes, sliced mushrooms, zucchini, pearl onions, thyme sprigs, and bay leaf.
Bring to a gentle boil, then reduce the heat to medium-low. Allow the ragout to simmer for 30 minutes, or until the vegetables are tender and the sauce has thickened.
Before serving, be sure to find and remove the thyme sprigs and bay leaf.
