Ingredients
Method
- Preheat oven to 350°F (175°C). Line a baking sheet with parchment. Blitz oats to a coarse powder, then whisk with milk, egg, Worcestershire, Dijon, salt, pepper, and thyme. Rest 5 minutes.
- Add onion and garlic, then fold in beef gently until just combined.
- Shape into a 9×5 inch loaf on the sheet. Mix ketchup, brown sugar, and vinegar; spread half over the top.
- Bake 40 minutes. Spread remaining glaze on top and bake another 15 to 20 minutes, to 160°F (71°C).
- Rest 10 minutes, then slice and serve with pan drippings.
Notes
For the most accurate doneness, use an instant-read thermometer. The meatloaf will continue to cook as it rests, so pulling it at 160°F is safe. If you’re short on time, make the glaze and meat mixture a day ahead and refrigerate, then shape and bake the next day—just add 5 to 10 minutes to the bake time.
