Chef’s Pro Tips for Perfect Results

Making this casserole is easy, but a few insider tricks can really take it over the top:

Instructions for Making Ground Beef Potato Casserole

Ready to get cooking? Here’s how to build this cozy casserole step-by-step.

1. Preheat Your Equipment:
   Preheat your oven to 375°F (190°C). Lightly grease a 9×13 inch baking dish.
2. Combine Ingredients:
   In a large skillet over medium heat, melt the butter. Add chopped onions and garlic, sauté until soft. Stir in the flour and cook for a minute. Slowly whisk in milk to form a creamy sauce. Season with salt, pepper, and thyme. In another pan, brown the ground beef until fully cooked.
3. Prepare Your Cooking Vessel:
   Make sure your baking dish is greased and ready for layering. Keep your ingredients nearby.
4. Assemble the Dish:
   Start with a layer of potato slices at the bottom. Spoon some of the cooked beef over the potatoes, then drizzle with creamy sauce. Repeat layers, finishing with a layer of potatoes topped generously with shredded cheese.
5. Cook to Perfection:
   Cover with foil and bake for 45 minutes. Remove foil and bake an additional 15 minutes until cheese is bubbly and golden.
6. Finishing Touches:
   Let the casserole rest for 10 minutes before cutting. This helps the layers set.
7. Serve and Enjoy:
   Slice into hearty squares and serve warm, maybe with a crisp side salad or steamed veggies.
