The simple prep makes it beginner-friendly, and the finished casserole is easy to pair with green beans, a crisp salad, or warm rolls. It also reheats well, which makes leftovers especially useful the next day. The full recipe is waiting here when you are ready to bring this easy Southern comfort classic to the table:

This recipe hits all the marks:
✔️ Just 5 core ingredients
✔️ Only 15 minutes of prep
✔️ One baking dish, no complicated steps
✔️ Comforting and full of flavor

It’s everything a casserole should be—hearty, tender, and layered with simple ingredients that bake together into something much greater than the sum of their parts. The slow oven time gives the potatoes time to soften and absorb all that tomato and beef flavor, while the onions and peppers melt down into sweet, savory goodness.

And the best part? You can dress it up with garlic powder, crushed red pepper, or even pepperoncini to make it your own.

🛒 Ingredients

• 1 pound lean ground beef (85–90% lean)
• 3 large russet potatoes, sliced ¼-inch thick
• 2 sweet onions, sliced ¼-inch thick
• 1 can (14.5 oz) diced tomatoes, preferably fire-roasted
• 2 medium green bell peppers, diced
• Salt and pepper, to taste

Optional Additions:

• 1 tablespoon diced butter
• ½ teaspoon garlic powder
• 1 teaspoon crushed red pepper
• Sliced pepperoncini (for topping)

Swaps and Notes

• Meatless version: Swap beef with plant-based ground meat or cooked lentils.
• Cheesy twist: Add shredded cheddar or mozzarella on top in the last 15 minutes.
• Spice it up: Jalapeños or red pepper flakes bring heat.
• Tomato variation: Use a can of Rotel or crushed tomatoes for a smoother sauce.

👩‍🍳 Step-by-Step Instructions

1️⃣ Preheat and Prep

• Preheat your oven to 350°F (175°C).
• Spray a 9×13-inch baking dish with nonstick cooking spray.

2️⃣ Brown the Beef

• In a skillet over medium-high heat, cook ground beef until no longer pink (about 8 minutes).
• Season with salt, pepper, and optional garlic powder or crushed red pepper.

3️⃣ Layer the Casserole

• In the prepared dish, layer potato slices evenly on the bottom.
• Season with salt and pepper, and dot with butter if using.
• Spread the cooked ground beef over the potatoes.
• Add onion slices on top of the beef.
• Pour over the diced tomatoes, including juices.
• Sprinkle green bell peppers across the top.

4️⃣ Bake

• Cover tightly with foil and bake for 2 hours.
• Optional: Remove foil during the last 10 minutes for a golden top.

5️⃣ Serve and Enjoy

• Let the casserole rest for 5–10 minutes before serving to set up the layers.
• Garnish with pepperoncini or chopped parsley if desired.

🔥 Tips for Success

• Thin potato slices = perfect texture. Use a mandoline if needed.
• Keep it covered: This locks in steam and helps everything cook evenly.
• No need to par-cook potatoes: The long bake time does all the work.
• Let it rest before serving—it’s hot and saucy right out of the oven.
