Keto Cheeseburger Casserole

KETO CHEESEBURGER CASSEROLE is always a winner if you are the kind of person who prepares dinner at the last minute. It’s always our fallback dish and the whole family will love it.

We have a few favorites up my sleeve but my go-to is always this recipe. We grew up eating this as it was our parent’s take on healthy fast food. We’ve made some small adjustments to the original recipe, but we can confirm it tastes just as good.

This recipe can be prepared exactly as specified and served with a side of vegetables. Or, to make it a full meal, you could add vegetables like cauliflower rice or spinach.

This easy 30-minute keto cheeseburger casserole makes a wonderful low-carb alternative to a classic cheeseburger and is hearty and filling. You won’t miss the bun!

In a delightfully non-gourmet sort of way, this casserole is so delicious. Kids and Grownups alike always enjoy it. You can vary the spices you use, you can make it as written, and you can add veggies. It’s a very forgiving and flexible recipe, like most casseroles.
