Regular ground beef works well in this recipe.
An 80/20 ground beef blend provides plenty of flavor, although leaner ground beef can also be used.
If you use very lean beef, the casserole may be slightly less rich.
Because the beef is the main source of savory flavor, don't be afraid to season it lightly with salt and pepper before assembling the casserole.
What Potatoes Work Best?
Almost any everyday potato can work.
Russet potatoes are a great option because they become tender and absorb the flavors of the casserole.
Yukon Gold potatoes are also delicious and have a naturally buttery texture.
The most important thing is to slice the potatoes fairly thinly and evenly.
That helps them cook at the same rate.
Nobody wants beautifully tender potatoes mixed with a few stubborn crunchy ones!!
Necessary Tools
You don't need much equipment.
You'll need:
- Large skillet
- 9×13-inch casserole dish
- Cutting board
- Sharp knife
- Wooden spoon or spatula
- Measuring spoons
- Aluminum foil
That's it!
Ingredient Additions and Substitutions
The beauty of a five-ingredient casserole is that it's easy to adapt.
Ground Beef
You can substitute ground turkey if you prefer.
Ground pork can also work, although it will change the flavor.
Potatoes
Use russet, Yukon Gold, red potatoes, or another good baking potato.
Green Beans
Canned green beans are convenient, but frozen green beans can work too.
If using frozen vegetables, there's generally no need to fully thaw them first.
Tomatoes
Diced tomatoes are an easy choice.
You can use plain diced tomatoes or a seasoned variety if you'd like a little extra flavor.
Add Cheese
If you don't mind moving beyond the original five ingredients, shredded cheddar cheese is a delicious addition.
Sprinkle it over the casserole during the final few minutes of baking and let it melt until bubbly.
Oh, yes!!
Add Seasonings
You can also customize the casserole with:
- Garlic powder
- Paprika
- Italian seasoning
- Onion powder
- Black pepper
- A pinch of red pepper flakes
Just remember that once you start adding extras, you're creating your own variation rather than sticking strictly to the five-ingredient version.
How to Make Dolly Parton’s 5-Ingredient Casserole
Step 1: Prepare the Oven
Preheat your oven to 350°F (175°C).
Lightly grease a 9×13-inch casserole dish.
Step 2: Brown the Ground Beef
Place a large skillet over medium heat.
Add the ground beef and cook until browned, breaking it apart with a spoon as it cooks.
Add the chopped onion and continue cooking until the onion begins to soften.
If there is a large amount of excess grease in the skillet, carefully drain it.
Step 3: Prepare the Potatoes
While the beef is cooking, wash and thinly slice the potatoes.
Try to keep the slices similar in thickness.
This little bit of consistency makes a big difference when everything is baking together.
Step 4: Start Layering
Arrange a layer of sliced potatoes in the prepared casserole dish.
Add some of the browned beef and onion mixture.
Then add the tomatoes and green beans.
Repeat the layers if needed, depending on the size and shape of your casserole dish.
Season lightly with salt and black pepper as you go.
Step 5: Cover and Bake
Cover the casserole tightly with aluminum foil.
Place it in the preheated oven and bake for approximately 60–75 minutes, or until the potatoes are fork-tender and the casserole is bubbling.
The exact cooking time can vary depending on how thinly the potatoes are sliced and how your oven heats.
Step 6: Uncover and Finish
Once the potatoes are tender, carefully remove the foil.
If you'd like a little browning on top, return the casserole to the oven uncovered for another 10–15 minutes.
If you're adding cheese, sprinkle it over the top during this final stage.
Bake until melted and bubbly.
Step 7: Rest Before Serving
Remove the casserole from the oven and let it rest for about 5–10 minutes.
This gives the juices a chance to settle and makes serving easier.
Then scoop it onto plates and enjoy!!
Tips for Making the Best Casserole
Slice the Potatoes Thinly
This is probably the most important tip.
Thick potato slices can take much longer to become tender.
Thin, even slices cook more consistently.
Don't Skip Browning the Beef
Browning adds flavor.
You could technically assemble everything without browning the beef first, but taking a few extra minutes to brown it gives the casserole a much deeper savory taste.
Drain Excess Grease
If your ground beef releases a lot of fat, drain some of it before assembling the casserole.
You want the dish moist and flavorful—not swimming in grease.
Cover the Casserole
The foil helps trap steam, which is important for cooking the potatoes and keeping the casserole moist.
Check the Potatoes
Don't rely entirely on the clock.
Insert a fork into the center of the casserole to make sure the potatoes are tender before serving.
Let It Rest
Give the casserole a few minutes after baking.
It will be extremely hot straight from the oven, and resting helps everything settle.
What to Serve With This Casserole
Because this dish already contains meat, potatoes, and vegetables, you don't need much on the side.
But if you want to round out dinner, try:
Simple Green Salad
A crisp salad with a light vinaigrette adds freshness.
Dinner Rolls
Soft rolls are perfect for soaking up the tomato juices.
Cornbread
For a Southern-inspired dinner, cornbread is a fantastic match.
Coleslaw
A cool, crunchy slaw provides a nice contrast to the warm casserole.
Pickles
Don't underestimate the power of a little acidity alongside rich comfort food!!
Can You Make This Casserole Ahead?
Yes.
You can assemble the casserole ahead of time, cover it tightly, and refrigerate it until you're ready to bake.
If you're assembling it in advance, keep it refrigerated and allow for additional baking time if the casserole is going directly from the refrigerator into the oven.
For food safety, don't leave the assembled casserole sitting at room temperature for an extended period.
How to Store Leftovers
Let leftover casserole cool and transfer it to an airtight container, or cover the casserole dish tightly.
Refrigerate leftovers and enjoy them within 3–4 days.
Reheat individual portions in the microwave or warm larger portions in the oven until heated through.
Can You Freeze It?
Yes, this casserole can be frozen, although potatoes can sometimes change texture after freezing and thawing.
For best results, cool the casserole completely before freezing it in an airtight, freezer-safe container.
Thaw it in the refrigerator before reheating.

Frequently Asked Questions
What are the five ingredients in Dolly Parton’s casserole?
The commonly shared five main ingredients are ground beef, onion, potatoes, tomatoes, and green beans.
Can I use fresh green beans?
Yes. Fresh green beans can be used, although you may want to trim and cut them before adding them to the casserole.
Can I use frozen green beans?
Yes. Frozen green beans are a convenient substitute for canned green beans.
Do I have to brown the ground beef first?
It's highly recommended. Browning develops a richer flavor and allows you to drain excess fat before the casserole goes into the oven.
Why are my potatoes not cooked?
The most common reasons are that the potato slices are too thick, the casserole wasn't covered tightly enough, or the casserole simply needs more time.
Slice the potatoes thinly and check them with a fork before removing the dish from the oven.
Can I add cheese?
Absolutely. Cheddar, Monterey Jack, or mozzarella can all make delicious additions.
Can I use ground turkey?
Yes. Ground turkey can replace ground beef, although the finished casserole will have a slightly lighter flavor.
Can I make this casserole vegetarian?
You can create a vegetarian variation by replacing the ground beef with a plant-based ground-meat alternative or another hearty ingredient.
The result won't be the traditional version, but it can still be delicious.
Can I make it in a smaller casserole dish?
Yes, but you may need to adjust the layering and cooking time. A deeper dish can also affect how quickly the potatoes cook.
