What you’ll need
To create this flavorful casserole, gather the following ingredients:
- 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)
- 2 tablespoons butter
- 1/4 cup shredded cheddar cheese (optional)
Feel free to substitute ground turkey or chicken for the beef if you’re looking for a lighter option. You can also use fresh vegetables if you prefer, but frozen ones are a quick and easy choice.

- Add the chopped onion and minced garlic to the skillet, cooking until softened, about 3-4 minutes.
- Stir in the frozen mixed vegetables, tomato paste, beef broth, Worcestershire sauce, salt, and pepper. Let it simmer for about 5-7 minutes until it thickens slightly.
- Transfer the beef mixture to a casserole dish, spreading it evenly.
- Top with the prepared mashed potatoes, ensuring they 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.

Best ways to enjoy it
This Shepherd’s pie casserole is best enjoyed fresh from the oven, but it pairs wonderfully with a simple side salad, crusty bread, or even steamed green beans for an extra touch of color and nutrition. If you’re feeling adventurous, a dollop of sour cream or a drizzle of barbecue sauce can add an exciting twist to each bite!
Storage and reheating tips
Once you’ve made this delicious casserole, you might have leftovers! Store any uneaten portions in an airtight container in the refrigerator for up to 3 days. To reheat, simply place it in the oven at 350°F (175°C) until heated through, or pop individual portions in the microwave for a quick meal. You can also freeze the casserole before baking it for up to 3 months; just let it cool completely and wrap it well.
Helpful cooking tips
To enhance the flavors, consider sautéing the onions and garlic longer for a deeper caramelization. If you’re short on time, you can use store-bought mashed potatoes or even frozen mashed potatoes to save on prep. And don’t skimp on the seasoning—this dish shines with just the right amount of salt and pepper.
Creative twists
Looking to switch things up? Try adding different vegetables, like spinach or mushrooms, or using a different protein like shredded chicken or lentils for a vegetarian option. For a touch of elegance, consider topping the mashed potatoes with fresh herbs like thyme or rosemary before baking.
