Ingredients
Here’s what you’ll need to create this scrumptious casserole:
- 1 pound ground beef
- 1 medium onion, chopped
- 2 cloves garlic, minced
- 1 cup frozen mixed vegetables (peas, carrots, corn)
- 2 tablespoons tomato paste
- 1 cup beef broth
- 1 teaspoon Worcestershire sauce
- Salt and pepper to taste
- 3 cups mashed potatoes (prepared from about 3 large potatoes)

For a twist, feel free to substitute ground turkey for a leaner option or swap the mixed vegetables for your favorites!
Directions
- Preheat your oven to 400°F (200°C).
- In a large skillet over medium heat, brown the ground beef. Drain any excess fat.
- Add the chopped onion and minced garlic to the skillet. Sauté for about 3-4 minutes, or until the onions are softened.
- Stir in the frozen mixed vegetables, tomato paste, beef broth, Worcestershire sauce, and season with salt and pepper.
- Let this mixture simmer for 5-7 minutes until it thickens slightly.
- Transfer the beef mixture to a casserole dish, spreading it evenly across the bottom.
- Top with your prepared mashed potatoes, spreading them to cover the filling completely.
- Dot the mashed potatoes with butter and sprinkle with shredded cheddar cheese if desired.
- Bake in the preheated oven for 20-30 minutes, or until the top is golden and bubbly.
- Allow it to cool for 5 minutes before serving.

Serving Suggestions
Pair this shepherd’s pie casserole with a fresh green salad drizzled with lemon vinaigrette for a refreshing contrast. It also goes wonderfully with a side of garlic bread, perfect for scooping up any delicious leftovers. If you want to elevate your meal, consider serving it with a dollop of sour cream or a sprinkle of fresh herbs for added flair.
Storage & Reheating
To keep your shepherd’s pie casserole fresh, store any leftovers in the refrigerator in an airtight container for up to 3-4 days. If you want to enjoy it later, freezing is an option too! Make sure it’s well-wrapped in freezer-safe packaging, and it can last for 2-3 months in the freezer. When you’re ready to enjoy it again, reheat in the oven at 350°F until warmed through, or microwave individual portions, taking care not to overcook.
Pro Tips
For a shortcut, use pre-made mashed potatoes to save time, or try adding a splash of cream to your mashed potatoes for extra richness. Don’t hesitate to tweak the vegetables based on what you have available—zucchini or bell peppers work beautifully too. And remember, letting the casserole rest before serving will enhance the flavors and make it easier to slice.
Variations
Feeling adventurous? Here are some creative twists you can try:
- Add a dash of hot sauce or cayenne pepper for a spicy kick.
- Introduce a layer of cheese into the beef mixture for extra richness.
- For a vegetarian version, swap the ground beef for lentils or a meat substitute.
- Experiment with different kinds of cheese on top, like mozzarella or a blend of Italian cheeses, for a cheesy delight!
FAQs
Can I make this recipe ahead of time?
Absolutely! You can prepare the casserole up to the baking stage, cover it tightly, and refrigerate it for up to 24 hours before baking. Just add a few extra minutes to the cooking time if baking straight from the fridge.
How do I reheat frozen shepherd’s pie?
To reheat a frozen casserole, let it thaw in the refrigerator overnight and bake as instructed. If baking from frozen, add 15-20 minutes to the cooking time and watch closely to prevent over-browning.
Can I use different vegetables?
Yes! Feel free to customize the vegetables to your liking. Fresh or frozen vegetables all work well, so use whatever you have on hand.
