Step-By-Step: Making Cottage Pie
Step 1: Cook the Beef Filling
Brown your ground beef in a pan. Add onions and carrots, and let them soften. Stir in tomato paste, Worcestershire sauce, and thyme. Pour in the beef stock and let it simmer until thickened. Toss in the peas at the end, nobody likes mushy peas.
Step 2: Make the Mashed Potatoes
Boil your potatoes until soft. Mash with butter, milk, salt, and pepper. Taste-test here (and maybe sneak a spoonful or two). Ever made mash without enough seasoning? Yeah, it ruins the whole thing.
Step 3: Assemble and Bake
Spread the beef filling in a casserole dish. Top with the mashed potatoes. Use a fork to create little ridges, this helps it crisp up beautifully in the oven. Bake at 200°C (400°F) for 20–25 minutes until golden.
