This is a hearty comfort food delicious meal which is heavy on the meat for sure (you can halve the recipe if preferred) - almost like a layered meat loaf in casserole form.  Amazing casserole that is so flavorful and it doesn't take much to satiate.  It is like eating steak in hamburger form!

Simple ingredients for the most part which means most of these ingredients are possibly already in your home. Whipping cream can be expensive, so use any low-carb milk; that's fine.  The cream cheese will ensure that the sauce is plenty thick and rich enough.

I normally just use the garden-variety sliced mushrooms sold in stores like Costco, but you can use your favorite mushrooms.

This recipe is definitely appropriate to feed a hungry family.  It is packed full of protein, good fats and nutrition.

Casseroles are easy and often ensure there is food for the next day or two as well.  Bonus!  A break for the busy cook!  Such a hearty casserole will never be turned down by a hungry husband.  How do I know? lol

These sorts of casseroles are fun and you can easily tweak them to your own taste.  So many possibilities with this casserole.  You could add sliced celery along with the onion and cook it until soft.  Or, you could add peppers to the onions.  You can even make it a bit spicier by adding sliced poblano peppers or canned jalapenos or green chilies.  So many options for variations to this casserole.  You could simply increase the heat by adding 1 tsp red pepper flakes.

I have another Hamburger Mushroom Bake recipe that uses eggs in the recipe, but this one does not.  I fry in olive oil but you can use butter or bacon fat or whatever you normally use!



3 lbs lean ground beef (1.36 kg)

1 cup chopped onion (250 mL)

2 slices bacon, diced

2 tsp salt (10 mL)

1/2 tsp Montreal Steak Seasoning (2 mL)

2 tsp minced garlic (10 mL)

1/4 tsp black pepper (1 mL)

1 tbsp extra-light olive oil (15mL)

1 lb sliced mushrooms (0.45 kg)

1/2 tsp seasoning salt (2 mL)

1/4 tsp black pepper (1 mL)

2 cups shredded Cheddar cheese (500 mL)

Creamy Sauce:

8 oz cream cheese (250 g)

1/2 cup whipping cream, OR (125 mL)

  half and half

1/2 cup water (125 mL)

2 tbsp extra-light olive oil (30 mL)


Preheat the oven to 350°F (180°C). 


In large nonstick frying pan, cook ground beef, onion and bacon together until the beef starts browning. While cooking, periodically use spatula to break up the ground beef into real small bits.  Sprinkle with salt, Montreal Steak Seasoning and add garlic and black pepper.  Continue cooking another 5 minutes.    Set aside.


In nonstick frying pan, over medium heat, in olive oil, cook mushrooms until the moisture evaporates.


In another nonstick frying pan or saucepot, combine cream cheese, whipping cream, OR half and half, water and olive oil.  Bring to the boil, whisking occasionally until the sauce is smooth.  Stir into the ground beef.


Layer half the ground beef in a 9 x 13-inch (23 x 33 cm) baking dish.  Sprinkle with half the Cheddar cheese.  Top with remaining ground beef and layer mushrooms over top.  Sprinkle with the other half of the Cheddar cheese.  Bake 25 minutes or until hot and bubbly.
