How to make Keto Cheeseburger Casserole

Making Keto Cheeseburger Casserole is easy and requires simple steps. Let’s break down the process and make sure you have everything you need to create this delightful dish.

Ingredients:

907 g extra lean ground beef
2 tsp coarse kosher salt
¼ tsp ground black pepper
1 tbsp minced garlic
60 ml avocado oil mayonnaise
60 ml unsweetened ketchup
1 tbsp mustard
1 medium onion, finely chopped
170 g shredded sharp cheddar cheese, divided
2 tbsp olive oil
Olive oil spray

Directions:

Preheat the oven to 204°C.
Lightly coat a 1.9 L baking dish with olive oil spray.
Heat olive oil in a large skillet over medium-high heat for 2 minutes.
Add chopped onions and ground beef to the skillet.
Cook the mixture, breaking up the beef and stirring until the beef is browned and onions are tender, approximately 5 minutes. If there is excess liquid, drain it, then return the mixture to the skillet.
Season with black pepper, minced garlic, and kosher salt. Stir and cook for several minutes to combine flavors.
Remove the skillet from heat. Stir in unsweetened ketchup, mayonnaise, mustard, and 113 g (1 cup) of shredded cheddar cheese until everything is well mixed.
Transfer the mixture evenly into the prepared baking dish. Sprinkle the remaining cheddar cheese on top.
Bake in the preheated oven for 15 minutes until the cheese is melted and the dish is heated through.
If the baking dish is broiler-safe, place it under the broiler 15 cm from the heating element for 1–2 minutes until the cheese is melted and lightly browned.
