This comfort-filled shepherds pie is a lifesaver for weeknights when time is tight but you crave something warm and satisfying. The ease of using tomato soup and instant potatoes means you can get a hearty casserole on the table with very little fuss. Even picky eaters dig in without complaints and everyone ends up asking for seconds.
This recipe became my standby the year my youngest would only eat mashed potatoes and cheese. Now it is a go-to for meal trains and potlucks when I need something comforting that works for all ages.
Ingredients
- Instant mashed potatoes: for a creamy and fluffy topping choose a brand with simple ingredients and no artificial flavors if possible
- Butter milk and salt: for rich flavor in the potatoes go for whole milk and unsalted butter for best results
- Ground beef: gives the casserole its hearty filling use 80 to 85 percent lean for enough flavor without excess grease
- Frozen mixed vegetables: for quick nutrition peas carrots corn and green beans are a classic mix make sure they are not freezer burned for best texture
- Tomato soup: adds sweetness and a classic tangy note choose a brand with real tomatoes and not too much sugar
- Beef stew seasoning packet: brings depth and savory richness try to find one without too many additives or MSG
- Water: to loosen the filling and help the seasoning blend distribute evenly
- Shredded cheddar cheese: for that golden crust on top sharp cheddar melts well and has bold flavor buy a block and shred it yourself if you have time
Step-by-Step Instructions
- Prepare the Potatoes:
- Make the instant mashed potatoes by following the box guidance using butter milk and salt. Fluff gently with a fork to keep them light and avoid overmixing which can make them gluey.
- Brown the Beef:
- In a large skillet over medium heat cook the ground beef breaking it up with a spatula. Stir and cook until no pink remains and the meat is starting to brown on the edges. Pour off any greasy liquid to keep the pie from getting soggy.
- Build the Filling:
- Add tomato soup frozen vegetables beef stew seasoning and water to the skillet. Stir well to combine and keep the heat on low. Let everything simmer for about ten minutes so the vegetables soften slightly and the flavors meld.
- Layer in the Casserole:
- Lightly grease a nine by thirteen inch baking dish. Spoon the beef filling evenly across the bottom making sure it is spread out for even coverage.
- Add the Mashed Potato Topping:
- Scoop the mashed potatoes onto the filling and gently spread with a spatula. Smooth the surface to cover every bit of meat and veggies.
- Cheese the Top and Bake:
- Scatter the shredded cheddar cheese over the potatoes so every bite gets a little cheese pull. Place in a four hundred degree oven and bake uncovered for thirty minutes. Watch for the cheese to melt and the top to bubble and take on some color.
- Rest and Serve:
- Take the casserole out and let it cool for five to ten minutes. This rest helps everything set up and makes it much easier to dish neat slices.

The cheese on top is my favorite part of this dish because it gets perfectly bubbly and crisp at the edges. My kids still argue over who gets the pieces with the most cheese and I secretly love it just as much as they do.
Storage Tips
Shepherds pie stores beautifully in the fridge. Just cover tightly with foil or transfer leftovers to an airtight container. It keeps fresh for up to four days and reheats easily in the microwave or oven. If you want to freeze it bake the casserole let it cool fully then wrap well. Thaw overnight in the fridge then reheat at three hundred fifty degrees covered until hot.
Ingredient Substitutions
No ground beef on hand Try ground turkey chicken or even lentils for a vegetarian twist. If you prefer homemade potatoes you will need about four large russets boiled and mashed with plenty of butter. For extra flavor stir in some garlic powder or use a different cheese blend like mozzarella and parmesan.
Serving Suggestions
While this dish is a meal in itself I love serving it with a simple green salad or steamed broccoli for a fresh crunch. Add a splash of hot sauce or a spoonful of sour cream on top to bring an extra layer of flavor. Leftovers are also fantastic as a filling for wraps or on toast the next day.
