This hamburger (ground beef) casserole is delicious, hearty, warming, and easy to put together! It is made simply with ground beef, mushrooms, garlic, parsley, sea salt, bacon, cream cheese, cheddar cheese and eggs. The cream cheese/egg combination replace non-keto-friendly canned soup. Eggs hold the casserole together, negating the need for breadcrumbs or a cornstarch-thickened sauce. Casseroles, or ‘hot dish’ as my family from Minnesota calls them, either evoke feelings of love or uneasiness.
If you have feelings of love for casseroles but don’t have feelings of love for canned soups, breadcrumbs, and other highly processed high-carb additions, you’re sure to love this recipe! All the classic casserole flavor (yes, leftovers are better the next day!) without sacrificing your health goals.
Substitutions and Food Allergy Notes
Meat substitution: We use elk in this casserole often. You can also substitute a combination of any other ground meat; turkey, chicken, pork, lamb, for some or all of the beef. This recipe is flexible! Substitute 1:1 ie 2 pounds of ground turkey can replace the 2 pounds of ground beef.
GAPS Diet: Dripped Yogurt Cheese should be used in place of the cream cheese for very strict GAPS. However, if you have been on GAPS for a while and are tolerating dairy well, many of us purchase cultured cream cheese from the store and use that. It’s not 100% perfect for very strict GAPS, but it will be sufficient for many and will greatly save your prep time!
Carnivore diet: Mushrooms are a grey area on the carnivore diet. Omit if you want to. This casserole made with meat, cream cheese, eggs, cheddar cheese, bacon, and sea salt is also delicious!
Egg allergy: I have made this recipe using gelatin in the place of eggs in this recipe. The results aren’t perfect, but the gelatin does help the casserole hold together, which is the purpose of the eggs here. To use gelatin in place of the egg, mix 2 tablespoons gelatin (find here) and 1/2 cup cold water with a fork or whisk. Allow gelatin to absorb liquid for 5 minutes, and then combine with the softened cream cheese mixture.
Dairy allergy: This recipe is dairy-heavy, in general when a recipe contains this much dairy it is difficult to make substitutions. I have not tried it, and cannot recommend it, BUT if you really want to try a substitution my best guess would be to use 1 can full fat coconut milk in place of the cream cheese, omit cheddar cheese, and double garlic to cover up the coconut flavor. We do have many dairy-free recipes, see them here.

Hearty and Warm Hamburger Mushroom Bake
- 2 lbs ground beef
- 2 teaspoons salt
- 1 teaspoon black pepper optional
- 4 cloves garlic crushed (optional)
- 12 ounces cream cheese GAPS used dripped yogurt cheese
- 6 eggs
- 4 slices bacon or 2 tablespoons butter+ fat for greasing pan
- 1 lb mushrooms
- 1 tablespoon parsley
- 2 cups cheddar cheese grated
Preheat oven to 350° F. Grease a 2-Liter (8 cup- dish shown is 8.5x11; 9x13 also is a good size) casserole dish with butter, bacon grease, or other desired fat.
In a large pan over medium heat, brown ground beef, sprinkle with 2 teaspoons salt and optional pepper.
As the ground beef browns, fry bacon in a large saute pan over medium heat, and remove once it is mostly cooked (reserve to chop and top casserole), leaving the grease in the pan.
Rinse mushrooms and slice or quarter as the beef is browning and the bacon is frying. Saute mushrooms in the bacon grease over medium-low heat until they are soft and stop releasing water, about 15 minutes. Mix with the browned ground beef.
In a food processor, with an immersion blender in a wide-mouth quart-sized mason jar, or with a whisk and a lot of perseverance, mix softened cream cheese and one egg at a time and optional crushed garlic until smooth.
Once cream cheese mixture is smooth, mix the browned ground beef mixture, sauteed mushrooms, parsley, and cream cheese mixture together. Pour into the greased casserole dish and press down gently until smooth.
Top with cheddar cheese and crumbled bacon, if you are doing the bacon version.
Place casserole dish on a cookie sheet, or over foil, in case it bubbles over.
Bake casserole for 35 minutes on the lowest rack until hot and bubbly. Allow to rest 20 minutes before serving so the casserole can set up. Enjoy!
Casserole can be frozen before baking. To freeze, cover tightly with plastic wrap or foil and slip into a freezer bag. Thaw before baking. If cold (from thawed) baking time will be longer- cook until heated through, approx 60 minutes.

Made this for Easter dinner! Thank you!
We ended up using ground turkey because that’s what we had on hand but we cooked it with tallow. Turned out delicious! It’s nice to make dinner all the family can enjoy!
