Keto Cheeseburger Casserole

Reminiscent of a cheeseburger without the bun. Fits perfectly into the keto diet. Made with ingredients you mostly likely have.

Ingredients :

• 1 teaspoon butter, or as needed
• 1 pound ground beef
• ½ cup diced onion
• 2 cloves garlic cloves, pressed
• salt and freshly ground black pepper to taste
• 1 cup shredded sharp Cheddar cheese, divided
• 2 tablespoons ketchup
• 2 tablespoons mayonnaise
• 2 tablespoons diced dill pickles
• ½ tablespoon mustard

Directions :

1. Preheat the oven to 400 degrees F (200 degrees C). Grease a baking dish with butter.
2. Cook ground beef and onion in a large, nonstick skillet over medium heat until beef is browned and onions are soft and translucent, 5 to 10 minutes. Add garlic and cook until fragrant, about 1 minute. Season with salt and pepper. Stir in 1/2 cup Cheddar cheese until well combined.
3. Remove from heat. Add ketchup, mayonnaise, pickles, and mustard. Transfer mixture to buttered baking dish and top with remaining 1/2 cup Cheddar cheese.
4. Bake in the preheated oven until cheese is melted, 7 to 10 minutes.
