Instructions

Step 1: Preheat oven to 375°F (190°C). Finely chop 1 cup mushrooms, 1/2 cup onion, and 2 garlic cloves. In a large bowl, combine 1.5 lbs ground beef, chopped mushrooms, onion, garlic, 1/2 cup bread crumbs, 1 egg, 1 tbsp Worcestershire sauce, 1 tsp Dijon mustard, 1 tsp salt, and 1/2 tsp pepper. Mix gently with hands until just combined—do not overwork.
Step 2: Press mixture evenly into a greased 9x5-inch loaf pan, smoothing the top. Bake for 45 minutes until internal temperature reaches 160°F (71°C).
Step 3: While meatloaf bakes, whisk 1 cup beef broth, 1 tbsp cornstarch, and 1 tbsp water in a small saucepan. Bring to a simmer over medium heat, stirring constantly until thickened and glossy (about 3 minutes, coating the back of a spoon).
Step 4: Remove meatloaf from oven, tent with foil, and rest for 10 minutes. Slice and serve with warm gravy.
