Ingredients
(Here’s a tip: Check out the full list of ingredients and measurements in the recipe card below.)
For the meat filling:
ground beef or ground lamb
olive oil
yellow onion, diced
garlic cloves, minced
carrots, diced
frozen peas
tomato paste
Worcestershire sauce
beef broth
dried thyme
salt
black pepper
For the mashed potato topping:
russet or Yukon gold potatoes, peeled and cubed
butter
milk
salt
black pepper
shredded cheddar cheese (optional)
Directions
I begin by preheating the oven to 400°F (200°C).
I boil the peeled and cubed potatoes in salted water until fork-tender, about 15–20 minutes. I drain them and mash with butter, milk, salt, and black pepper until smooth and creamy. I set them aside.
In a large skillet, I heat olive oil over medium heat and sauté the diced onion until soft. I add the minced garlic and cook briefly until fragrant. I stir in the ground beef or lamb and cook until browned, breaking it up as it cooks.
I add the diced carrots and cook for a few minutes until slightly softened. Then I stir in tomato paste, Worcestershire sauce, dried thyme, salt, and black pepper. I pour in the beef broth and let the mixture simmer for about 8–10 minutes until slightly thickened. I fold in the frozen peas at the end.
I transfer the meat mixture into a greased baking dish and spread it evenly. I spoon the mashed potatoes over the top and smooth them out. If I am using cheese, I sprinkle shredded cheddar over the potatoes.
I bake the casserole for 20–25 minutes, or until the top is lightly golden and the filling is bubbling. I let it rest for a few minutes before serving.
Servings and Timing
I usually get about 6 servings from this recipe.
Prep time: 20 minutes
Cook time: 35–40 minutes
Total time: About 1 hour
Variations
I sometimes mix corn into the filling for extra sweetness. When I want a lighter option, I use ground turkey instead of beef or lamb. For extra flavor, I add a splash of red wine to the meat mixture while it simmers. If I prefer a crispier topping, I broil the casserole for a few minutes at the end.
Storage/Reheating
I store leftovers in an airtight container in the refrigerator for up to 4 days. To reheat, I warm individual portions in the microwave or reheat the entire dish covered in the oven at 350°F (175°C) until heated through. I can also freeze it for up to 2 months and thaw overnight before reheating.
