Ingredients & Substitutions
Ground Beef: You will need 1 lb (450g) of lean ground beef. Cooking this until crumbled and deeply browned develops the essential savory foundation of the casserole.
Yellow Onion: Use 1/2 cup (75g) of diced yellow onion. Sautéing these until translucent provides a subtle, sweet aromatic flavor that balances the rich meat.
Olive Oil: Use 1 tbsp (15ml) of extra virgin olive oil for searing. This invisible foundational ingredient helps achieve that necessary golden crust on the beef.
Cream Cheese & Heavy Cream: A blend of 4 oz (115g) cream cheese and 1/2 cup (120ml) heavy cream is essential. Together, they melt down to form the base of the thick creamy off-white sauce.
Beef Broth: Add 1/2 cup (120ml) of beef broth to thin the dairy into a cohesive gravy. It amplifies the meaty flavor while maintaining the sauce’s thick, rich texture.
Garlic Powder, Salt & Pepper: Use 1/2 tsp (1g) garlic powder, 1 tsp (5g) salt, and 1/2 tsp (1g) black pepper. These foundational seasonings are crucial for elevating the savory profile of the dish.
Orange Cheddar Cheese: You will need 1.5 cups (170g) of freshly grated orange cheddar cheese. This creates the iconic thick, bubbly blanket with golden-brown toasted spots on top.
Fresh Parsley: Finish the dish with 1 tbsp (4g) of finely chopped fresh green parsley flakes. This provides a bright, fresh contrast to the rich, melted cheese.
Equipment Needed
- Rectangular Glass Baking Dish: Essential for monitoring the slightly crispy edges pulling away from the sides.
- Large Skillet: Needed to properly sear the beef and create the thick creamy sauce.
- Cheese Grater: Freshly grating your cheddar ensures a smoother, more bubbly melt.
- Wooden Spoon: Perfect for scraping up the browned bits of beef from the bottom of your skillet.
Step-by-Step Instructions
1. Prepare Your Equipment
Preheat your oven to 375°F (190°C). Lightly grease a rectangular glass baking dish with non-stick spray or a touch of butter.
Using a glass dish is critical here. It allows you to watch the cheese develop those glorious crispy edges pulling away from the sides.
2. Sear the Ground Beef
Heat 1 tbsp (15ml) of olive oil in a large skillet over medium-high heat. Add the 1 lb (450g) of ground beef to the hot pan.
Cook the meat, breaking it apart with a wooden spoon, until you achieve crumbled, deeply browned cooked ground beef. Do not rush this step; the deep browning is essential for a rich flavor profile.
3. Sauté the Onions
Once the beef is browned, lower the heat to medium. Add the 1/2 cup (75g) of diced yellow onions into the skillet with the beef.
Cook for about 3 to 4 minutes, stirring frequently. You are looking for translucent diced onions that have absorbed the savory beef drippings.
4. Build the Creamy Off-White Sauce
Reduce the heat to medium-low. Add the 4 oz (115g) of cubed cream cheese, 1/2 cup (120ml) heavy cream, 1/2 cup (120ml) beef broth, garlic powder, salt, and pepper.
Stir continuously as the cream cheese melts. Simmer for 3 to 5 minutes until the liquids reduce and combine into a rich, thick creamy off-white sauce that thoroughly coats the crumbled beef.
5. Assemble the Casserole
Carefully transfer the meaty, creamy mixture into your prepared rectangular glass baking dish. Use a spatula to spread it into an even base layer.
Sprinkle the 1.5 cups (170g) of grated orange cheddar cheese evenly over the top. Ensure the cheese reaches all the way to the edges of the dish.
6. Bake to Perfection
Place the glass baking dish in the preheated oven. Bake for 15 to 20 minutes.
Watch for visual cues: the top layer should become a thick, bubbly blanket of melted orange cheddar cheese. Look closely for golden-brown toasted spots and slightly crispy edges pulling away from the sides of the glass dish.
7. Garnish and Serve
Remove the casserole from the oven and let it rest on a neutral minimalist countertop for 5 minutes. This resting period helps the thick creamy sauce set slightly.
Generously sprinkle the finely chopped bright green fresh parsley flakes over the melted cheese before serving. Enjoy the ultimate low-carb comfort meal!
Expert Tips for Success
- Grate Your Own Cheese: Pre-shredded cheese contains anti-caking agents that prevent a smooth melt. Freshly grated orange cheddar ensures that thick, bubbly blanket you desire.
- Do Not Drain All the Fat: A small amount of beef fat helps emulsify the cream cheese into a perfectly thick creamy off-white sauce.
- Watch the Edges: Keep an eye on the glass dish while baking. The casserole is done the moment you see slightly crispy edges pulling away from the sides.
- Broil for Extra Color: If your casserole is bubbly but lacks golden-brown toasted spots, switch your oven to broil for 1 to 2 minutes. Watch it closely to prevent burning!
Storage & Reheating/Freezing
Store any leftover Keto Ground Beef Casserole in an airtight container in the refrigerator for up to 4 days. The thick creamy off-white sauce will solidify when cold but melts beautifully upon reheating.
To reheat, place a portion in the microwave for 1 to 2 minutes, or reheat in a 350°F (175°C) oven until warmed through. For freezing, wrap the baked and cooled casserole tightly in plastic wrap and foil; freeze for up to 3 months. Thaw overnight in the fridge before reheating.

Frequently Asked Questions
Yes! You can tightly wrap the baked and cooled casserole in plastic wrap and aluminum foil, then freeze it for up to 3 months. Thaw overnight in the refrigerator before reheating in the oven.
Absolutely. While ground beef provides a classic rich flavor, you can substitute it with ground turkey or ground chicken. Just ensure you sear it well in olive oil to build the foundational savory flavors.
The combination of full-fat cream cheese and heavy cream naturally reduces into a rich, thick creamy off-white sauce when simmered over medium-low heat. No flour or cornstarch is required!
Freshly grated orange cheddar cheese is highly recommended. Pre-shredded cheeses contain anti-caking agents that prevent a smooth melt. Grating it yourself ensures golden-brown toasted spots and a bubbly texture.
A watery casserole usually happens if you do not let the heavy cream and broth simmer long enough to thicken, or if your onions release too much water. Make sure to simmer the sauce until it thoroughly coats the beef before baking.
