    💡 Tips for Making Keto Big Mac Casserole

    • For the meat, I use 85% ground beef that's organic and grass-fed.  On Keto, you can certainly use 80%, but you'll want to make sure and really drain off any extra fat before adding to the casserole.
    • For the best melty texture, shred your cheddar cheese from a block. Pre-shredded cheese often has anti-caking agents that can affect how it melts.
    • Be careful not to overbake it. Keep an eye on the casserole while it’s in the oven. Overbaking can dry it out, so pull it as soon as the center is set and the cheese is melted.
    • After baking, let the casserole sit for about 5–10 minutes before serving. This allows it to firm up and makes it easier to slice and serve.

    ☑️ Storage Instructions

    This is one of those casseroles where the leftovers not only taste great, but I think they taste even better! Store leftovers in the fridge for a few days. It also freezes and reheats really well, so it's perfect for meal prepping.  

    You can portion out and freeze in an air tight container for up to a couple of months for those days when you're pressed for time and need something you can thaw and reheat easily.

    🍴 What to Serve with Hamburger Casserole

    This is a very filling casserole so a simple salad or a side of you favorite veggies is all you need. Here some options:

    • Overnight 7 Layer Salad
    • Oven Roasted Vegetables
    • Israeli Salad
    • Roasted Cauliflower Steaks
    • Broccoli Salad

    🔄 Substitutions and Additions

    • Eggs: I used 4 eggs in this casserole, primarily to act as a binder.  If you want more of a quiche-like consistency, you can add 2-4 additional eggs. The eggs I use are cage-free and organic.
    • Bacon: I also used uncured bacon that has the lowest carbs and sugar. I prefer my bacon and cold cuts with no nitrates but sometimes you cannot avoid a smidge of sugar.
    • Cheese: The cheese I used is sharp cheddar, which is my favorite to serve on burgers.  If you don't like sharp cheddar, use any cheddar you like.  Or you can use a different cheese all together, like Monterey Jack or Colby, if that's what you like or have on hand. Keep in mind, though it does save time using pre-shredded, by shredding your own cheese, you avoid the anti-caking ingredients some brands use that may have hidden carbs.
    • Veggies: I used yellow onion, garlic and mushrooms in the mix, but if you want to omit either, you can.  Keep in mind, they all contribute to the flavor of this casserole, so if you omit them, I'd replace with something else.  Peppers would be a good alternative, if that's what you like. 
    • Mustard: I also added Worcestershire, sugar-free ketchup (I used G.Hughes, it's my favorite) and yellow mustard to give the casserole a more burger-like flavor.  If you prefer spicy mustard, you can use it instead. You can add more or less, depending on your taste.  I think the recipe has a good balance as is.
    • Sauce: You can also give the casserole a more barbecue like flavor by substituting Low Carb BBQ sauce for the ketchup and mustard. The great thing is you can customize this casserole to your liking, depending on how you like your burgers to taste.  So if there are other toppings that you prefer, by all means use what ever you like!

    Can I Make this Casserole Ahead of Time?

    Absolutely! Assemble it up to a day in advance, cover tightly, and store in the fridge. Bake just before serving.

    Why is My Casserole Watery?

    Excess liquid can come from not draining the ground beef or bacon properly. Make sure to drain grease thoroughly before mixing the ingredients.

    How Do I Prevent The Eggs From Curdling?

    Use room-temperature ingredients and avoid overcooking. Mixing the eggs well with the cream and dressing helps create a smooth texture.

    How Do I Serve Keto Cheeseburger Casserole?

    I tried several different ways of serving this casserole.  I added chopped cooked bacon over the top because, well, who doesn't LOVE bacon!

    I also added shredded lettuce, tomatoes from my garden and pickle.  You can serve this way or you can also add a drizzle of mustard and ketchup or even mayonnaise, if you'd like. Alternatively, you can drizzle some Thousand Island Dressing over the top, which is great as well!

      Kid approved! We all agreed it was absolutely delicious, and going in the meal rotation. The only changes I made was to use G. Hughes Thousand Island dressing, reduced to half the amount called for because the flavor is so strong, left the pickles and mushrooms out of the mixture due to preference, and reduced the amount of onion due to preference. Thank you for a great meal!

      I'm just starting on Keto and this recipe was easy and very good! I left out the mushrooms as my hubby won't eat them. Added a little more ground beef. I had leftovers to freeze for later.
      Thanks Julianne

      Hi Julianne

      I am interested in making your casserole. If I am making just for myself, is it more cost-saving and time-saving to make a small portion or using a bigger gratin dish to make a big serving size and save the rest (if I have a budget to adhere to)?

      Is Worcestershire sauce consider keto-friendly? Can I opt out of Worcestershire sauce?

      Thanks,
      Evonne

        It truly is optional either way. You can meal prep by making the entire recipe and freeze a portion of it or you can cut the ingredients in half and make half a casserole. I prefer the meal prep route because it means only cooking once. This recipe only uses one tablespoon of Worcestershire sauce for the whole 10 servings, so the carb impact is super minimal. You can omit it or use liquid aminos in its place. I hope you enjoy it!

        You might try coconut flour or a combination of psyllium husk powder and coconut flour. But since I've never tried it before, I can't say for sure how it might turn out.
