BEST EVER BEEF AND POTATOES CASSEROLE

Steps:

• Preheat the oven to 350 degrees F (175 degrees C). Slice potatoes into medium rounds.
• Heat vegetable oil in a deep skillet over medium heat. Fry potato rounds until starting to turn brown, about 5 minutes per batch. Remove from oil and place on a paper towel-lined plate to drain. Set aside.
• Heat olive oil in a frying pan over medium-high heat. Cook onion and garlic in the hot oil until onion turns translucent, about 5 minutes. Add ground beef and cook and stir until browned and no pink remains, 5 to 7 minutes more. Drain the pan.
• Combine beef mixture and cream of chicken soup in a large bowl. Add mild Cheddar cheese and stir until combined. Season with salt and pepper.
• Combine panko bread crumbs with 1/3 of the Irish Cheddar cheese and melted butter.
• Spray a 2-quart baking dish with cooking spray and spread 1/2 of the potatoes in the bottom of the dish. Sprinkle with 1/3 of the Irish Cheddar cheese. Cover with 1/2 of the beef mixture. Repeat with remaining potatoes, Irish Cheddar, and beef mixture. Top with panko mixture.
• Bake, uncovered, in the preheated oven until browned and bubbly, about 30 minutes.
