I first created this Hearty Ground Beef & Potato Bake with Mushroom Sauce on a total whim. It was one of those frantic weeknights where everyone was hungry, and my fridge was looking pretty bare. I had some ground beef, a few potatoes, and a lonely carton of mushrooms staring back at me.
I decided to throw it all together in a casserole dish, hoping for the best. The result was this incredibly comforting, one-pan wonder that my family now requests weekly. My secret? I don’t precook the potatoes. They cook right in the savory sauce, soaking up all that amazing flavor.

Why This Recipe is So Special
What truly sets this dish apart is the technique. By layering everything raw, the magic happens in the oven.
The potatoes become perfectly tender. The beef browns beautifully. And the mushroom sauce thickens into a rich, creamy gravy. It’s a true set-it-and-forget-it meal that delivers maximum flavor with minimal fuss.
The Full Ingredient List
I love how simple this list is. You probably have most of these staples in your kitchen right now!
- 1.5 lbs lean ground beef
- 2 lbs russet potatoes, thinly sliced
- 1 large yellow onion, diced
- 8 oz cremini mushrooms, sliced
- 2 cups beef broth
- 1 cup heavy cream
- 1/4 cup all-purpose flour
- 2 tsp Worcestershire sauce
- 1 tsp garlic powder
- 1 tsp dried thyme
- 1.5 cups shredded cheddar cheese
- Salt and black pepper to taste
My Step-by-Step Method
Follow these steps, and you really can’t go wrong. I’ve made this so many times it’s like second nature to me now.
- Preheat your oven to 375°F (190°C). Grease a 9×13 inch baking dish.
- In a large bowl, toss the thinly sliced potatoes with the flour, garlic powder, thyme, salt, and pepper. This coating is key for a perfectly thickened sauce.
- Spread half of the potato slices evenly on the bottom of the prepared baking dish.
- In the same bowl, combine the raw ground beef, diced onion, and Worcestershire sauce. Mix it gently with your hands until just combined.
- Press the beef mixture evenly over the first layer of potatoes in the dish.
- Arrange the remaining potato slices over the beef layer. Then, scatter the sliced mushrooms on top.
- In a separate bowl or large measuring cup, whisk together the beef broth and heavy cream. Slowly pour this mixture evenly over the entire casserole.
- Cover the dish tightly with foil and bake for 45 minutes. This steams the potatoes and cooks the beef through.
- Carefully remove the foil. Sprinkle the shredded cheddar cheese evenly over the top.
- Return the dish to the oven, uncovered, and bake for another 15-20 minutes, or until the cheese is bubbly and golden brown. Let it rest for 10 minutes before serving.
My Top Tips for Success
These little tricks are what I’ve learned from making this over and over. They make a big difference!
- Slice Potatoes Thinly and Evenly: Use a mandoline if you have one. This ensures everything cooks at the same rate.
- Let it Rest: I know it’s tempting to dig right in, but letting it sit for 10 minutes allows the sauce to thicken up perfectly.
- Brown the Top: If your cheese isn’t as golden as you’d like after baking, pop it under the broiler for a minute or two. Just watch it closely!
- Fresh Herbs for Garnish: A sprinkle of fresh chopped parsley right before serving adds a beautiful pop of color and freshness.

Nutrition Information
Avoid using overly fatty ground beef. The excess grease can make the final dish a bit oily. I find 85/15 or 90/10 lean beef works best.
Don’t skip the resting time. Cutting into it immediately will result in a soupy consistency. Patience is a key ingredient here!

FREQUENTLY ASKED QUESTIONS
Can I make this dish ahead of time?
Absolutely! You can assemble the entire casserole, cover it, and refrigerate it for up to 24 hours before baking. Just add about 10-15 minutes to the baking time since it will be going into the oven cold.
What can I use instead of heavy cream?
For a lighter version, you can use half-and-half. The sauce might be a touch less rich, but it will still be delicious. I don’t recommend using milk, as it can curdle.
Can I freeze the leftovers?
Yes, this dish freezes wonderfully. Let it cool completely, then portion it into airtight containers. It will keep for up to 3 months. Thaw in the refrigerator overnight before reheating.
