Ingredients

Instructions

  1. Step 1: Preheat oven to 375°F. In a large skillet, melt 2 tbsp butter over medium heat. Add 1 lb ground beef and cook until browned, breaking into small pieces with a wooden spoon (5-7 minutes), then drain excess fat. Add 1 large yellow onion, finely diced, and 2 cloves garlic, minced, and cook for 2 minutes until softened.
  2. Step 2: Stir in 1/4 cup all-purpose flour and cook for 1 minute, then gradually whisk in 1 cup beef broth and 1/2 cup whole milk until the sauce thickens and coats the back of a spoon (3-4 minutes).
  3. Step 3: Add 3 large russet potatoes, peeled and diced into 1/2-inch cubes, along with 1 tsp dried thyme, 1/2 tsp salt, and 1/4 tsp black pepper. Stir to combine, then transfer the mixture to a greased 9x13-inch baking dish. Top with 1/2 cup shredded cheddar cheese and bake for 25-30 minutes until potatoes are tender and cheese is golden.
