Instructions

  1. Step 1: Preheat oven to 375°F (190°C). Boil potatoes until fork-tender (15-20 minutes), then drain and mash with 1/4 cup milk, 1 tbsp butter, 1/4 tsp salt, and 1/8 tsp pepper until smooth.
  2. Step 2: Brown ground beef in a skillet over medium heat for 5-7 minutes, breaking into crumbles. Add diced onions and cook until translucent (3 minutes).
  3. Step 3: In the same skillet, melt 1 tbsp butter over medium heat, whisk in flour for 1 minute to form a roux. Gradually whisk in beef broth, thyme, 1/4 tsp salt, and 1/8 tsp pepper. Simmer for 5 minutes until thickened, then stir in 1/4 cup milk and remove from heat.
  4. Step 4: Spread half the mashed potatoes in a 9x13-inch baking dish. Layer with browned beef mixture, then the remaining mashed potatoes. Sprinkle shredded cheese evenly over the top.
  5. Step 5: Bake uncovered for 25 minutes until cheese is bubbly and golden, and edges are lightly browned. Let rest for 10 minutes before serving.
