Ingredients:
- 1 pound ground beef or lamb
- 1 medium onion, diced
- 2 cloves garlic, minced
- 2 cups mixed vegetables (carrots, peas, corn)
- 2 tablespoons tomato paste
- 1 tablespoon Worcestershire sauce
- 1 teaspoon dried thyme
- 1 teaspoon dried rosemary
- Salt and pepper to taste
- 4 cups mashed potatoes (prepared from scratch or store-bought)
- 1 cup shredded cheddar cheese (optional)
- 2 tablespoons olive oil
Preparing the Meat Filling
- In a large skillet, heat the olive oil over medium heat. Once hot, add the diced onion and sauté for about 3-4 minutes until it becomes translucent.
- Add the minced garlic to the skillet and cook for an additional 1 minute, stirring frequently to prevent burning.
- Increase the heat to medium-high and add the ground beef or lamb. Cook until browned, breaking it apart with a spatula, about 5-7 minutes.
- Once the meat is browned, drain any excess fat from the skillet.
- Stir in the tomato paste, Worcestershire sauce, dried thyme, dried rosemary, salt, and pepper. Mix well to combine all the flavors.
- Add the mixed vegetables to the skillet and stir until they are evenly distributed. Cook for an additional 5 minutes, allowing the vegetables to soften slightly.
Preparing the Mashed Potatoes
- If you are making mashed potatoes from scratch, peel and chop about 4-5 medium-sized potatoes. Place them in a large pot and cover with cold water.
- Bring the water to a boil over high heat, then reduce to a simmer. Cook the potatoes for about 15-20 minutes or until they are fork-tender.
- Drain the potatoes and return them to the pot. Add butter, milk, salt, and pepper to taste. Mash until smooth and creamy. Set aside.
- If you are using store-bought mashed potatoes, simply heat them according to the package instructions and set aside.
Assembling the Casserole
- Preheat your oven to 400°F (200°C).
- In a 9×13 inch baking dish, spread the meat and vegetable mixture evenly across the bottom.
- Carefully spoon the mashed potatoes over the meat mixture, spreading them out with a spatula to cover the entire surface. Make sure to seal the edges to prevent the filling from bubbling over.
- If desired, sprinkle the shredded cheddar cheese evenly over the top of the mashed potatoes for an extra cheesy layer.
Baking the Casserole
- Place the assembled casserole in the preheated oven and bake for 25-30 minutes, or until the top is golden brown and the edges are bubbling.
- If you want a crispier top, you can broil the casserole for an additional 2-3 minutes, but keep a close eye on it to prevent burning.
- Once done, remove the casserole from the oven and let it cool for about 5-10 minutes before serving. This will help the layers set a bit.
Serving Suggestions
- Serve the Shepherd’s Pie Casserole warm, garnished with fresh parsley if desired.
- This dish pairs wonderfully with a simple green salad or crusty bread for a complete meal.
- Leftovers can be stored in an airtight container in the refrigerator for up to 3 days. Reheat in the oven or microwave before serving.
Tips for Success
- Feel free to customize the mixed vegetables based on your preferences or what you have on hand. Green beans, bell peppers, or mushrooms can also work well.
- If you prefer a creamier mashed potato topping, consider adding sour cream or cream cheese to the potatoes before mashing.
- For a vegetarian version, substitute the meat with lent
