Crockpot Hamburger Potato Casserole is the weeknight meal I make when my family craves something hearty but I do not want to fuss over the stove for hours. Tender potatoes layer with savory ground beef and a creamy cheese sauce that make the house smell like comfort itself. If you want a filling dinner with minimal cleanup and maximum flavor this dish checks every box.

After a long day I love walking into the aroma of dinner already done. The first time I made this for my husband he was convinced I had ordered takeout because it tasted so good.

Ingredients

  • Ground beef: provides the savory protein base use lean for less grease or regular for extra flavor
  • Russet or Yukon gold potatoes: bring hearty thickness and hold their shape when slow cooked choose firm potatoes without blemishes
  • Onion: builds flavor throughout the casserole pick a fresh firm onion with no soft spots
  • Cheddar cheese: melts for richness and a bubbly golden top use sharp for tangy bite or mild for creamy melt
  • Cream of mushroom soup: adds moisture and ties flavors together look for a high quality soup for best results
  • Milk: thins the sauce and ensures a creamy texture whole milk adds richness
  • Garlic powder: gives gentle depth and warmth use fresh if you love a garlicky kick
  • Salt and pepper: sharpen flavors always taste and adjust before serving
  • Fresh parsley or chives (optional): for a pop of color choose crisp green herbs

Step-by-Step Instructions

Brown the Beef and Onion:
Cook ground beef and the chopped onion in a large nonstick skillet over medium heat for 5 to 7 minutes. Stir often and break up the meat well until no pink remains and onions are soft. Drain all excess fat to prevent the casserole from being greasy
Prepare the Potatoes:
Wash the potatoes thoroughly and slice very thin about one eighth inch thick. Uniform slices ensure the potatoes cook evenly and get tender not mushy. Use a mandoline if you have one for best results
Layer the Ingredients:
In your slow cooker spread half of the sliced potatoes on the bottom creating an even layer. Sprinkle half of the cooked beef and onions on top then add about a third of the shredded cheddar cheese. Repeat with the remaining potatoes and beef mixture ending with another layer of cheese
Mix and Pour Sauce:
In a medium bowl whisk together cream of mushroom soup milk garlic powder salt and pepper until totally smooth. Pour this sauce evenly over the casserole layers so everything gets a creamy coating
Cook on Low:
Put the lid on your slow cooker and cook on the low setting for 6 to 8 hours. The potatoes should be fork tender and the cheesy top perfectly melted with bubbly edges
Add Finishing Cheese and Herbs:
About fifteen minutes before serving sprinkle the rest of the cheddar cheese on the hot casserole. Cover again so the cheese melts to a luscious finish. Top with chopped parsley or chives if desired for freshness

Cheddar cheese is hands down my favorite part of this casserole. My grandmother used to sneak me the crusty cheesy edge pieces and it is now the most fought over portion in my own kitchen.

Storage Tips

Let the casserole cool completely then transfer leftovers to airtight containers. This dish keeps well in the fridge for up to three days and can be reheated in the microwave or oven. If you want to freeze it let portions cool first and wrap tightly in foil before placing in freezer bags. It will keep its flavor and texture for up to two months.

Ingredient Substitutions

You can swap ground turkey or chicken for the beef for a lighter take. Sweet potatoes add a slightly sweet twist and pair beautifully with cheddar. If you are dairy free use your favorite unsweetened milk alternative and a dairy free cheese. Cream of chicken or celery soup works as a flavorful substitute for mushroom soup.

Serving Suggestions

Spoon the casserole into shallow bowls alongside a crisp green salad or steamed green beans for a well rounded meal. Warm dinner rolls or crusty bread soak up the extra creamy sauce. For gatherings you can double the recipe and serve straight from the slow cooker to keep everything hot for seconds.

What You’ll Need to Make This

→ Main

01 450 grams ground beef (lean or regular)
02 4 to 5 medium russet or Yukon gold potatoes, thinly sliced (approximately 3 mm thick)
03 1 medium onion, chopped
04 200 grams shredded cheddar cheese, divided
05 300 grams canned cream of mushroom soup
06 120 millilitres milk
07 0.5 teaspoon garlic powder
08 Salt, to taste
09 Black pepper, to taste

→ Garnish (optional)

10 Fresh parsley, chopped
11 Chopped chives

How to Prepare

Step 01

Sauté ground beef with chopped onion in a skillet over medium heat until the beef is fully browned with no pink remaining, about 5 to 7 minutes. Drain any excess fat to reduce greasiness.

Step 02

Rinse potatoes thoroughly and slice them into uniform pieces, approximately 3 millimetres thick, ensuring even cooking.

Step 03

Arrange half of the sliced potatoes at the base of the slow cooker, followed by half of the cooked beef and onion mixture and a portion of shredded cheddar cheese.

Step 04

Layer the remaining potatoes, then add the rest of the beef and onion mixture and another portion of cheddar cheese, reserving some cheese for finishing.

Step 05

In a bowl, whisk together cream of mushroom soup, milk, garlic powder, salt, and black pepper until smooth. Evenly pour this mixture over the layered ingredients in the slow cooker.

Step 06

Cover and cook on low setting for 6 to 8 hours, until the potatoes are tender and the cheese has melted and become bubbly.

Step 07

Approximately 15 minutes prior to serving, sprinkle remaining cheddar cheese over the top. Cover and allow cheese to melt. Finish with fresh parsley or chopped chives if desired.

Extra Tips

  1. For best results, use a mandoline or sharp knife to achieve uniformly thin potato slices and ensure even cooking.
  2. Draining rendered fat after browning beef prevents excessive greasiness in the final dish.
  3. Gently layer ingredients to maintain distinct textures within the casserole.
  4. If the casserole appears dry during cooking, add a small amount of milk or broth as needed.
  5. Cooking on a low heat allows flavors to meld and ensures potatoes are fully tender without breaking down.
