Ingredients
Casserole
- 2 lb ground beef

- 2 teaspoon fine sea salt
- 1 ½ teaspoon coarse black pepper
- 2 tablespoon extra virgin olive oil divided
- ½ cup chopped white onion
- 16 oz riced cauliflower

- ½ cup mayo

Instructions
- Mix the ground beef with fine sea salt, ground black pepper, and minced garlic in a medium-sized bowl.
- Heat 1 tablespoon of olive oil in a cast iron skillet over medium heat. Saute the riced cauliflower and onion until cooked through. Remove from the skillet and set aside.
- While the veggies are cooking, make the Big Mac sauce by combining the mayo, pickle relish, ketchup, mustard, monk fruit, garlic salt, and onion powder in a small bowl.
- Add the seasoned ground beef mixture to the skillet and brown until cooked through. Drain the grease.
- Add the softened cream cheese to the skillet and stir until it's melted. Mix in the cooked cauliflower rice and onion.
- Top the cheeseburger casserole with shredded cheddar cheese.
- Bake at 375 degrees Fahrenheit for 20 minutes until cooked heated through, bubbling, and the cheese is melted.
- Serve the Big Mac casserole with Big Mac toppings: sliced pickles, chopped tomatoes, shredded iceberg lettuce, minced white onion, sesame seeds (or everything but the bagel seasoning), and drizzle with our Big Mac sauce (see Note below). Serve and enjoy!
Notes
A cast iron skillet is recommended since it's stovetop and oven safe and cuts back on the number dishes needed. If you don't have one, transfer the casserole ingredients to a 1 ½ quart baking dish before baking.
To save time you can skip the homemade Big Mac sauce and use a low carb store-bought sauce like Sir Kensington's Special Sauce or simply drizzle the casserole with ketchup and mustard.
