This hamburger potato casserole brings together two pounds of seasoned meat, tender sliced potatoes, and a creamy cheese sauce in the slow cooker, creating the kind of hearty comfort food that makes everyone feel genuinely taken care of without requiring hours of active kitchen time. The combination of ground beef and Italian sausage creates more complex, interesting flavor than either meat alone could achieve, while the cream of chicken soup base transforms into a rich, velvety sauce that coats every potato slice. What makes this hamburger potato casserole so perfect for busy families is the true set-it-and-forget-it convenience of the slow cooker method, allowing the potatoes to become fork-tender and the flavors to meld together while you handle everything else demanding your attention. Whether you're feeding a crowd that appreciates stick-to-your-ribs comfort food, needing a reliable weeknight dinner that essentially cooks itself, or simply craving the kind of cheesy, meaty, potato-loaded meal that makes cold evenings feel warmer, this slow cooker casserole delivers complete satisfaction with minimal effort.

I developed this recipe during a particularly overwhelming season when I still wanted to provide nourishing, homemade meals for my family without being tethered to the stove. The slow cooker became my ultimate solution. Returning home after a long day to a house that smells this incredible—and a dinner that is already finished—is a small luxury that makes the daily grind much easier. My kids now associate this meal with the comfort of coming home on those long, chilly winter days.

Master Your Ingredients

  • Ground Beef & Italian Sausage: One pound of each. The sausage contributes fennel, garlic, and herbs that elevate the beef's heartiness
  • Russet Potatoes: Four pounds, sliced to 1/4-inch thickness. Russets are high in starch, helping to thicken the sauce as they cook
  • Cream of Chicken Soup: Two cans serve as the creamy foundation, ensuring the dish stays moist and velvety over long cooking times
  • Sweet Onion & Garlic: A medium Vidalia onion and four fresh cloves provide a savory aromatic base that mellows beautifully in the slow cooker
  • Cheddar Cheese: Two cups of shredded sharp cheddar. Added in the final hour, it creates the essential indulgent topping
  • Spice Blend: Garlic powder and red pepper flakes add a subtle warmth that cuts through the richness of the cream and meat

Slow Cooker Strategy

The Flavor Foundation:
Brown the beef and Italian sausage in a skillet with the onions and garlic. This step is non-negotiable—it develops a deep, savory flavor (the fond) that raw meat simply can't provide.
Sauce and Assembly:
In the slow cooker, whisk together the soups, milk, and spices. Fold in the browned meat and the sliced potatoes. Toss everything gently to ensure every potato slice is coated in the liquid—this prevents them from browning or cooking unevenly.
Low and Slow:
Cook on low for 4 hours. At this point, stir the mixture and top with the shredded cheese. Continue cooking for another 1–2 hours until the potatoes are fork-tender and the cheese has transformed into a gooey, melted blanket.

If you find yourself without a slow cooker, you can adapt this for the oven. Use a 9x13 pan, slice the potatoes a bit thinner (1/8-inch), and bake covered at 350°F for about an hour before uncovering to melt the cheese. The slow cooker is preferred, however, as the long, gentle heat truly allows the sausage and beef fats to emulsify into the potato starch for a much richer result.

Creative Variations

For a spicy kick, use hot Italian sausage or add a can of diced green chiles to the meat mixture. You can also swap the cheddar for smoked gouda to add a sophisticated, woodsy depth. If you want more vegetables, stir in a bag of frozen peas or corn during the final hour of cooking for a pop of color and sweetness.

Storage and Reheating

Leftovers keep beautifully in the fridge for up to four days. As the dish sits, the potatoes will absorb more of the sauce, so the texture may get thicker. To reheat, add a small splash of milk and use the microwave or a low-heat skillet to bring back that creamy, 'fresh-from-the-pot' consistency.

Frequently Asked Questions

→ Can I make this in the oven instead of a slow cooker?
Yes! The recipe includes full oven instructions in the notes. Slice the potatoes thinner (1/8 inch), layer everything in a 9x13 dish, and bake at 350 degrees.
→ Can I use a different type of sausage?
Absolutely! Regular breakfast sausage, spicy Italian sausage, or even ground turkey sausage would all work great.
→ Why are my potatoes still hard after cooking?
Make sure the potatoes are submerged in the liquid as much as possible. If they're still hard, keep cooking on low for another hour or so, checking every 30 minutes.
→ Can I prep this the night before?
You can brown the meat ahead of time, but don't slice the potatoes until you're ready to cook - they'll turn brown. Assemble everything in the morning and start the slow cooker.
→ What can I serve with this?
This is pretty hearty on its own! A simple side salad or some green beans would round out the meal nicely.
→ Can I freeze leftovers?
Potatoes don't freeze great - they get grainy when thawed. This is best stored in the fridge for up to 3 days and reheated.

Ingredients

→ For the Casserole

01 4 lbs russet potatoes, cleaned and sliced to 1/4 inch thick
02 1 lb ground beef
03 1 lb Italian sausage
04 1 medium sweet onion, diced
05 4 cloves garlic, minced

→ For the Sauce

06 2 cans cream of chicken soup
07 1 1/2 cups milk
08 1/2 teaspoon salt
09 1/2 teaspoon black pepper
10 1/2 teaspoon garlic powder
11 1/2 teaspoon red pepper flakes

→ For Topping

12 2 cups shredded cheddar cheese

Instructions

Step 01

In a large skillet over medium heat (or use the sauté function of your crockpot if it has one), add the ground beef and Italian sausage. Brown on each side, breaking it up as it cooks. Add the diced onions and minced garlic. Sauté until fragrant, about 2 minutes, stirring frequently.

Step 02

Transfer the meat mixture to your crockpot. Add the cream of chicken soup, milk, and all the seasonings - salt, pepper, garlic powder, and red pepper flakes. Stir everything together with the meat, then add the sliced potatoes. Toss everything together, making sure to submerge the potatoes into the liquid as much as possible.

Step 03

Cover and cook on low for 4 hours or on high for 2 hours. Give it a stir and make sure the potatoes are nestled under the liquid. Top with the shredded cheese and keep cooking until the potatoes are fork tender - about 1 to 2 more hours.

Step 04

Serve warm and enjoy this hearty, comforting casserole!

Notes

  1. Slice the potatoes to 1/4 inch for the slow cooker - they need to be a bit thicker so they don't turn to mush.
  2. You can also make this in the oven! See the notes section for full oven instructions with slightly adjusted ingredient amounts.
  3. If your crockpot has a sauté function, you can brown the meat right in it to save on dishes.
  4. Stir the casserole partway through cooking to make sure everything cooks evenly.
  5. This is perfect for a set-it-and-forget-it dinner on busy days!
