• 1.5 lbs ground beef
• 1 onion, diced
• 3 cloves garlic, minced
• 2 tablespoons tomato paste

How to make keto cheeseburger casserole (step by step)

1. Preheat the oven to 375°F (190°C) and grease a baking dish.
2. Brown the ground beef with the onion, then add the garlic, tomato paste, mustard, salt, and pepper. Cook 2 minutes and drain excess fat.
3. Spread the beef mixture in the baking dish.
4. Whisk the eggs and heavy cream, stir in half the cheese, and pour over the beef. Top with the remaining cheese.
5. Bake for 25-30 minutes, until set and golden. Top with bacon and pickles before serving.

Food safety: cook ground beef to a safe minimum internal temperature of 160°F (71°C). An instant-read thermometer is the surest way to check — see the FoodSafety.gov chart.

Tips for the best results

• Drain the beef so the casserole is not greasy.

Variations & substitutions
