Crock Pot Hamburger Casseroles
Crock Pot Big Mac Casserole is a quick ground beef recipe the whole family will gobble up. I love a good hamburger casserole like Crock Beefy Potato Casserole or Tater Tot Taco Casserole. Casseroles are always my go-to because my kids love ground beef as much as the adults do and they are easy to throw into the crock pot and dinner is done. Big Mac Casserole is another one of those family-friendly meals that everyone will request!

Crock Pot Big Mac Casserole Special Sauce
This special sauce can be made in a few minutes with a few ingredients. Just make sure to make enough because everyone will want more to drizzle on their Big Mac Hamburger Casserole. Sometimes I double the recipe so there is more for leftovers too!
How to Make Special Sauce?
- ½ cup mayonnaise
- 2 Tablespoons ketchup
- 4 teaspoons sweet pickle relish
- 1 Tablespoon grated white onion

Tips to Make the Special Sauce

Crock Pot Big Mac Casserole - Gluten Free and Low Carb Casserole
All of my recipes are Gluten Free because my husband had celiac disease. That means you are allergic to gluten. However, this recipe is naturally gluten free so you don't need to make any swaps.
Keto Version
If you are following a Keto diet this recipe can work for you! Just swap a few of the ingredients.
- Swap the ketchup for sugar free ketchup.
- Use dill pickle relish instead of sweet pickle relish.
- Replace the sugar with Erythritol Sweetener.
How to Store Big Mac Casserole
Leftover Big Mac casserole can be stored in the fridge for up to 3 days. Be sure to store it in an airtight container so that it doesn't dry out. I like to freeze the casserole for up to 2 months. Thaw it overnight in the fridge and then reheat it in a 350-degree oven until warm.
Variation Options for Big Mac Casserole Recipe

- BBQ style: Swap out the special sauce for your favorite BBQ sauce.
- Southwest style: Add some diced green chiles, corn, and black beans to the mix.
