Ingredients
- Russet potatoes thinly sliced: These form the comforting base and soften beautifully during baking Select potatoes that are firm and free from blemishes
- Lean ground beef browned and crumbled: This adds deep savory flavor Use freshly ground beef from a trusted butcher for the best taste
- Large onions sliced and rings separated: They bring sweetness and fragrance Use yellow onions for a balanced flavor
- Tomatoes fresh sliced or canned diced: Both options lend juiciness and mild acidity Choose ripe tomatoes or a high quality canned brand
- Green bell peppers chopped: Their crunch and bright flavor really wake up the casserole Look for firm peppers with shiny skin
- Kosher salt and freshly ground black pepper to taste: These season every layer Choose freshly ground pepper and a flaky salt if possible
- Olive oil as needed: Used for drizzling and keeping everything tender Look for cold pressed extra virgin olive oil
Step-by-Step Instructions
- Prepare the Oven:
- Set your oven to three hundred fifty degrees Fahrenheit and allow it to fully preheat so your casserole cooks evenly
- Grease the Baking Dish:
- Lightly grease a nine by thirteen inch baking dish with butter or a neutral oil spray making sure to cover all corners for easy serving later
- Layer the Potatoes:
- Spread an even layer of thinly sliced russet potatoes over the bottom of the dish ensuring they overlap slightly to create a solid foundation
- Add Olive Oil:
- Drizzle a small amount of olive oil over the potatoes to help them caramelize and soften as they bake
- Layer the Beef:
- Scatter the browned and crumbled lean ground beef across the potatoes pressing lightly so it nestles in and flavors seep through
- Add the Onions:
- Distribute the sliced onion rings evenly over the beef letting their sweetness infuse the meat below
- Add Tomatoes:
- Layer freshly sliced tomatoes or spoon canned diced tomatoes evenly over the onions letting the juices soak down for extra flavor and moisture
- Add Bell Peppers:
- Sprinkle the chopped green bell peppers over the tomato layer distributing them for a bit of crunch and bright color in every bite
- Season Each Layer:
- After each main ingredient layer give a light seasoning with kosher salt and black pepper This brings out each vegetable’s natural flavor
- Bake Covered:
- Cover the entire dish tightly with aluminum foil and place in the preheated oven Bake for two hours so the vegetables become tender and the flavors meld beautifully
- Cool and Serve:
- Remove the dish from the oven and let it cool for about ten minutes before serving This helps the casserole set and makes it easier to slice into neat portions
