Ingredients
- 3 large russet potatoes, thinly sliced

Ingredient Notes
Russet Potatoes
Russet potatoes work well because they are sturdy and bake beautifully. Slice them thinly so they cook evenly and become tender.
Ground Beef
Lean ground beef keeps the casserole hearty without making it too greasy. Brown and crumble the beef before layering for the best flavor and texture.
Onions
Sliced onions add natural sweetness as they bake. Separate the rings so they cook evenly throughout the casserole.
Tomatoes
Fresh sliced tomatoes add bright flavor, while canned diced tomatoes are convenient and juicy. Either option works well.
Green Bell Peppers
Bell peppers add color, freshness, and a mild savory flavor that pairs beautifully with the beef and potatoes.
Olive Oil
A light drizzle of olive oil helps the potatoes cook and adds richness to the dish.
How to Make Southern Five Layer Beef Casserole
Step 1: Preheat the Oven
Preheat your oven to 350°F.
Lightly grease a 9×13-inch baking dish with butter or nonstick cooking spray.
Step 2: Prepare the Potatoes
Thinly slice the russet potatoes.
For extra tender potatoes, you can parboil the slices for 3–5 minutes, then drain well before layering.
Step 3: Start the First Layer
Arrange the sliced potatoes evenly in the bottom of the prepared baking dish.
Drizzle lightly with olive oil.
Season with salt and black pepper.
Step 4: Add the Beef Layer
Spread the browned and crumbled ground beef evenly over the potatoes.
Season lightly again with salt and pepper.
Step 5: Add the Onion Layer
Place the sliced onion rings over the beef.
Spread them out evenly so they bake into the casserole.
Step 6: Add the Tomato Layer
Add sliced fresh tomatoes or evenly spoon the canned diced tomatoes over the onions.
Step 7: Add the Bell Pepper Layer
Top with chopped green bell peppers.
Season the top with a little more salt and black pepper.
Step 8: Cover and Bake
Cover the baking dish tightly with aluminum foil.
Bake for 2 hours, or until the potatoes are tender and the casserole is bubbling.
Step 9: Rest and Serve
Remove the casserole from the oven.
Let it rest for 5–10 minutes before serving.
Serve warm.
Tip for Perfect Potatoes
For the best texture, parboil the potato slices for 3–5 minutes before layering them in the casserole. This helps them cook through fully and become tender by the time the casserole is finished baking.
It also helps the potatoes absorb more flavor from the beef, tomatoes, onions, and peppers.
Tips for the Best Southern Beef Casserole
Slice the potatoes thinly so they cook evenly.
Brown the beef before adding it to the casserole.
Season each layer lightly for the best flavor.
Cover the dish tightly with foil to trap moisture.
Let the casserole rest before serving so the layers settle.
Use lean beef to prevent excess grease.
Add extra vegetables if you want a heartier casserole.
Easy Variations
Cheesy Five Layer Beef Casserole
Sprinkle shredded cheddar or Monterey Jack cheese over the top during the last 10 minutes of baking.
Spicy Southern Beef Casserole
Add sliced jalapeños, chili powder, cayenne pepper, or crushed red pepper flakes.
Sweet Potato Version
Replace russet potatoes with thinly sliced sweet potatoes for a slightly sweeter flavor.
Extra Vegetable Casserole
Add zucchini, mushrooms, corn, carrots, or celery between the layers.
Ground Turkey Version
Use ground turkey instead of beef for a lighter casserole.
Tomato Sauce Version
Add a small amount of tomato sauce or crushed tomatoes for a saucier casserole.

Frequently Asked Questions
