How To Make Ground Beef and Potato Casserole (Step-By-Step)

Step 1: Prep the Oven & Dish

Preheat the oven to 350°F (180ºC) and lightly grease a casserole dish with nonstick cooking spray or butter.

Step 2: Cook the Ground Beef & Veggies

Heat a non-stick skillet on medium-high heat and brown the beef. Once the beef is nicely browned on all sides, add the diced onions and mushrooms and cook for a few more minutes until the onions are translucent. Add the potatoes and Worcestershire sauce and mix well to combine everything together.

Step 3: Make the Cream Sauce

Add the butter and flour to a separate large skillet. Cook for a couple of minutes until it has the consistency of a thick paste and a film has formed in the bottom of the skillet. Then add the milk and broth and cook for a couple of minutes until it thickens. Add the sour cream to the soup mixture and mix well.

Step 4: Assemble the Casserole

Transfer the ground beef mixture to your prepared baking dish and spread it out evenly. Top it with all of the cream sauce and finish it off with the shredded cheddar cheese.

Step 5: Bake & Serve

Cover the dish with aluminum foil and bake it for about 1 hour. Serve the casserole warm with fresh parsley on top, and enjoy!

Pan Size And Bake Time

Doneness cues: Knife slides through potatoes easily and the center is bubbling. If browning too fast, re-cover loosely with foil. Rest 10 minutes before slicing.

Pro Tips For The Best Ground Beef and Potato Casserole

• Break up the ground beef for better browning:
  Use a wooden spoon or meat chopper to break the beef into small, even pieces as it cooks. This allows more surface area to brown, which adds deeper flavor to the casserole and helps the meat cook more evenly.
• Use cream cheese for a velvety finish:
  Replacing sour cream with softened cream cheese makes the casserole creamier and gives it a slightly tangy richness. If you're looking for something indulgent and ultra-smooth, this is the move.
• Stick with russet potatoes for structure:
  Russet potatoes are starchy and hold up well during baking, which means they stay tender without turning mushy. Waxy potatoes like red or Yukon Golds will work, but they’ll give you a softer, more delicate texture.
• Season the beef as it cooks—don’t wait:
  Ground beef is your flavor foundation. Add garlic powder, onion powder, smoked paprika, chili powder, or even a pinch of cumin while browning. For added flavor and color, toss in diced bell peppers, jalapeños, or even sautéed mushrooms during this step.
• Want heat? Add it early:
  Stir in a few dashes of hot sauce, crushed red pepper flakes, or diced green chiles as the beef cooks. This lets the heat blend into the dish rather than just sitting on top after baking.
• Don’t skip the resting time.
  After baking, let the casserole rest for 5–10 minutes before serving. This helps the sauce thicken, the flavors settle, and makes slicing and serving much easier.

Recipe Variations

• Cheeseburger-Style – Swap the sour cream for mayonnaise and use cheddar cheese. Add chopped pickles and a drizzle of ketchup or burger sauce after baking for a fun twist on a classic cheeseburger.
• Tex-Mex Style – Add taco seasoning, drained black beans, and frozen corn to the cooked ground beef. Top with shredded pepper jack cheese and serve with salsa or a dollop of sour cream.
• Loaded Baked Potato – Stir in cooked bacon, green onions, and use cream cheese instead of sour cream for extra richness. Top with sharp cheddar and more bacon bits before baking.
• Mushroom & Swiss Version – Add sautéed mushrooms to the ground beef while cooking and swap the cheddar for Swiss cheese for a savory, earthy flavor combo.
• Spicy Kick – Stir in diced jalapeños, chipotle powder, or a splash of hot sauce into the beef mixture before layering. Top with a spicy cheese blend or pepper jack.
• Low-Carb Option – Substitute the potatoes with cauliflower florets or turnips for a lighter, keto-friendly version. You may need to reduce the bake time slightly since cauliflower cooks faster.

FAQs About This Ground Beef Potato Casserole Recipe

Can I make this casserole ahead of time?

Yes! This ground beef and potato casserole is a great make-ahead meal. You can fully assemble it—cooked beef, layered potatoes, sauce, and cheese—and store it unbaked in the refrigerator for up to 24 hours. When you’re ready to cook, simply remove it from the fridge, let it sit at room temperature for 15 minutes, and then bake as directed.

How Should I Store and Reheat This Casserole

• Store: Cool completely. Cover and refrigerate up to 4 days.
• Freeze: Wrap tightly (whole pan or portions) for up to 2 months. Thaw in the fridge overnight.
• Reheating in the oven: 325°F (165°C), covered, 15–25 minutes (single portions 10–15 minutes). Uncover for the last 3–5 minutes to re-crisp the top.
• Reheating in the microwave: Cover loosely and heat 60–90 seconds per portion, stirring once if needed.
• Keep it creamy: If the casserole seems dry after chilling, stir in 1–2 tablespoons milk or broth before reheating.

Can I use a different type of meat?

Absolutely. You can substitute ground turkey, chicken, or sausage for the ground beef. Just make sure to adjust the seasoning as leaner meats may need a little extra flavor.

Do I need to cook the potatoes first?

No, the potatoes cook right in the casserole as it bakes. Just make sure to dice them into small, even pieces so they soften fully and cook at the same rate as the beef and sauce.

Can I freeze this casserole before baking?

Yes, but with a small adjustment: assemble the casserole in a freezer-safe dish, skip the cheese topping, and wrap tightly with plastic wrap and foil. Freeze for up to 3 months. When ready to bake, thaw overnight in the fridge, add the cheese, and bake as directed.

What’s the difference between this no-soup casserole and a canned soup version?

This recipe builds creaminess with a simple roux (butter + flour + milk/broth), so the sauce tastes fresher and you control the salt. If you want the canned soup version, try our hamburger potato casserole.
