Method
- Preheat your oven to 375°F (190°C).
- Boil the potatoes in a saucepan of salted water until tender, about 15-20 minutes. Drain well.
- While potatoes boil, heat olive oil in a large skillet over medium-high heat. Add ground beef and cook, breaking it up, until browned. Drain off excess fat.
- Add chopped onion, carrots, and celery to the skillet. Cook until softened, about 5-7 minutes.
- Stir in minced garlic and tomato paste. Cook for 1 minute more.
- Pour in beef broth and Worcestershire sauce. Add thyme, salt, and pepper. Bring to a simmer and cook for 5 minutes, allowing the sauce to thicken slightly.
- Mash the drained potatoes with warm milk, butter, salt, and pepper until smooth and creamy.
- Pour the beef mixture into a 9x13 inch baking dish.
- Spread the mashed potatoes evenly over the beef mixture.
- Bake for 20-25 minutes, or until the topping is golden brown and the filling is bubbly.
- Let stand for 5-10 minutes before serving.
Notes
For an extra layer of flavor, you can add a tablespoon of flour to the beef mixture before adding the broth to help thicken the sauce.
