FILLING:
- 3 pounds ground beef medium or lean
- 1 large yellow onion chopped
- 3 medium celery stalks minced
- 3 tablespoon tomato paste
- 3 cups beef stock low sodium
- 2 ½ tablespoon Worcestershire sauce
- ½ tablespoon sea salt
- ½ tablespoon fresh thyme
- 1 teaspoon ground black pepper
- 4 tablespoon cold water
- 3 tablespoon cornstarch
- 2 cups frozen peas and carrots
TOPPING:
- 3 pounds russet potatoes peeled and cut
- 10 tablespoon milk
- ½ stick unsalted butter
- 3 cups gruyere cheese shredded
- 1 teaspoon sea salt
Cook beef on medium-high heat until almost fully browned then drain most of the excess fat.
Add chopped onion and celery and cook for 5 minutes.
Cook tomato paste for 2 minutes, then pour in beef stock, along with Worcestershire sauce, salt, thyme and black pepper.
Bring to a boil then reduce the heat and cover for 20 minutes.
While beef cooks, add potatoes to a large pot and bring to a cook for about 15-20 minutes, until potatoes are fork tender.
Drain potatoes, then melt butter before adding the potatoes back to the pot with cheese, milk and salt. Mash to your desired consistency (taste and season to your preference).
Preheat oven to 350F.
When the beef is completed, it covered simmer, mix and add in the cornstarch slurry. Cook uncovered for an additional 10-20 minutes or until it has thickened (you do not want to remove all liquid but most).
Mix in frozen peas and carrots, then transfer to a 9x13 baking. Carefully place mashed potato on top and lightly scrape with a fork to leave lines, if desired (I tend to place cobble stones of potatoes on top to make it even, since it cannot be spread on top).
Bake for 25 minutes, uncovered. If desired, broil until golden.
- Simmer the Filling: Giving the meat mixture time to simmer helps develop a thicker, richer gravy.
- Smooth Mashed Potatoes: Mash while the potatoes are hot for the fluffiest texture.
- Even Layers Matter: Spread both the beef filling and potato topping evenly for consistent baking.
- Golden Finish: Broil briefly at the end if you want a lightly golden top.
- Best Base Flavor: Let the beef cook just until mostly browned.
- Refrigerator: Store leftovers in an airtight container for up to 4 days.
- Freezer: Cottage pie freezes well for up to 2 months when tightly wrapped.
- Reheating: Reheat in the oven at a low temperature until warmed through.
