Ingredients

Instructions

  1. Step 1: Preheat oven to 375°F (190°C). Grease a 9x13-inch baking dish with 1 tsp butter.
  2. Step 2: Boil 2 cups diced potatoes in salted water for 10 minutes until fork-tender. Drain thoroughly and set aside.
  3. Step 3: Melt 3 tbsp butter in a medium saucepan over medium heat. Whisk in 1/4 cup flour and cook for 1 minute. Gradually pour in 2 cups milk while whisking, then add 1/2 tsp garlic powder, 1/4 tsp dried thyme, 1/2 tsp salt, and 1/4 tsp black pepper. Cook until thickened and coating the back of a spoon (about 5 minutes).
  4. Step 4: Layer half of the drained potatoes (1 cup), half of the broccoli (1 cup), and half of the cheddar (1/2 cup) in the baking dish. Pour half of the sauce (1 cup) over the layers. Repeat with remaining potatoes, broccoli, cheddar, and sauce.
  5. Step 5: Sprinkle 1/2 cup panko evenly over the top and dot with remaining 1 tsp butter. Bake for 25-30 minutes until golden and bubbling around the edges.
