Ingredients
For this casserole I focus on a balance of protein, low‑carb vegetables, and a decadently cheesy sauce. Ground beef supplies the savory backbone, while cauliflower rice adds bulk without the carbs. The cheese mixture—sharp cheddar, cream cheese, and heavy cream—creates a silky coating that mimics the melt of a classic cheeseburger. Aromatics like onion, pickles, and a dash of mustard bring that unmistakable burger zing, and a handful of seasonings tie everything together.
Main Ingredients
- 1 lb ground beef (80 % lean)
- 3 cups cauliflower rice (fresh or frozen, thawed)
- 1 medium onion, diced
- ½ cup dill pickles, finely chopped
Cheese Mixture
- 1 ½ cups shredded sharp cheddar cheese
- 4 oz cream cheese, softened
- ½ cup heavy cream
Sauce & Flavor Boosters
- 2 tablespoons yellow mustard
- 1 tablespoon tomato paste
- 1 teaspoon Worcestershire sauce
Seasonings
- 1 teaspoon garlic powder
- 1 teaspoon onion powder
- ½ teaspoon smoked paprika
- Salt and freshly ground black pepper, to taste
Each component plays a purpose: the beef supplies protein and that familiar burger flavor, while cauliflower rice absorbs the sauce without turning mushy. The cheese mixture melts into a creamy blanket that keeps the casserole moist. Mustard, tomato paste, and Worcestershire sauce add tang, depth, and a hint of umami that replicate the classic fast‑food taste. Finally, the seasoned blend of garlic, onion, and smoked paprika lifts the dish, delivering a balanced, satisfying bite every time.
Step-by-Step Instructions

Preparing the Ingredients
Begin by preheating your oven to 375°F (190°C). While the oven warms, dice the onion, chop the pickles, and if using frozen cauliflower rice, thaw it in the microwave and squeeze out excess moisture with a clean kitchen towel. This step prevents a watery casserole and ensures a firm texture.
Cooking the Beef
- Brown the beef. Heat a large skillet over medium‑high heat, add a splash of olive oil, then crumble the ground beef into the pan. Cook, stirring occasionally, for 5–6 minutes until the meat is fully browned and any liquid has evaporated. Browning creates Maillard‑derived flavor that mimics a grilled burger patty.
- Season and aromatize. Sprinkle garlic powder, onion powder, smoked paprika, salt, and pepper over the meat. Add the diced onion and continue sautéing for 2–3 minutes until the onion softens and becomes translucent, releasing sweetness that balances the savory beef.
- Incorporate the pickles and sauces. Stir in the chopped dill pickles, mustard, tomato paste, and Worcestershire sauce. Cook for another minute, allowing the flavors to meld and the tomato paste to darken slightly, which deepens the overall umami profile.
Creating the Cheesy Base
- Blend the cheese mixture. In a medium bowl, whisk together softened cream cheese, heavy cream, and half of the shredded cheddar until smooth. This creates a thick, velvety sauce that will coat the cauliflower rice and beef evenly.
- Combine cauliflower rice. Add the drained cauliflower rice to the skillet, stirring to incorporate it with the seasoned beef. Cook for 2 minutes so the rice absorbs some of the juices, preventing a soggy final dish.
- Mix in the cheese sauce. Pour the cheese mixture over the beef‑cauliflower blend, stirring gently until everything is uniformly coated. The sauce should look glossy and cling to each morsel, indicating proper emulsification.
Baking the Casserole
Transfer the entire mixture to a greased 9‑x‑13‑inch casserole dish. Sprinkle the remaining shredded cheddar evenly across the top. Place the dish in the preheated oven and bake for 20–25 minutes, or until the cheese on top is bubbling and lightly golden. A brief broil (1–2 minutes) at the end adds a perfect crust without burning.
Finishing & Serving
Remove the casserole from the oven and let it rest for 5 minutes. Resting allows the sauce to thicken slightly, making slicing cleaner and preserving juiciness. Garnish with a sprinkle of fresh chives or a few extra pickles for color, then serve hot straight from the dish.
Tips & Tricks
Perfecting the Recipe
Dry the cauliflower rice. After thawing, press the rice between paper towels to remove excess water; this prevents a soggy casserole and gives a firmer bite.
Use 80 % lean beef. The slight fat content keeps the meat moist and adds flavor while still fitting a low‑carb profile.
Don’t over‑mix the cheese sauce. Stir just until combined; over‑mixing can cause the sauce to separate during baking.
Let the casserole rest. A 5‑minute rest after baking locks in juices and makes portioning cleaner.
Flavor Enhancements
Add a teaspoon of smoked liquid smoke for an extra “grilled” flavor, or stir in a handful of crumbled cooked bacon just before baking for smoky crunch. A splash of apple cider vinegar at the end brightens the sauce and balances the richness.
Common Mistakes to Avoid
Skipping the step of drying cauliflower rice often leads to a watery casserole. Also, baking at too high a temperature can scorch the cheese while leaving the interior undercooked. Stick to 375°F and use a thermometer to confirm the internal temperature reaches 160°F for safety.
Pro Tips
Grate cheese fresh. Freshly grated cheddar melts more evenly than pre‑shredded varieties, which often contain anti‑caking agents that affect texture.
Use a cast‑iron dish. Cast iron distributes heat uniformly, giving a beautifully browned top without burning.
Season in layers. Add a pinch of salt after each major step to build depth rather than dumping it all at once.
Finish with fresh herbs. A sprinkle of chopped chives or parsley right before serving adds a pop of color and fresh flavor.
Variations
Ingredient Swaps
Replace ground beef with ground turkey or Italian sausage for a lighter or spicier profile. Swap cauliflower rice for shredded broccoli stems or a mix of zucchini and mushrooms to change the vegetable base. For a dairy‑free version, use shredded dairy‑free cheddar and coconut cream instead of heavy cream.
Dietary Adjustments
To keep the dish strictly keto, substitute the tomato paste with a tablespoon of tomato sauce thickened with xanthan gum and replace the mustard with a sugar‑free dijon. For a vegetarian take, use crumbled tempeh or plant‑based ground “beef” and ensure the cheese is vegetarian‑friendly.
Serving Suggestions
Pair the casserole with a simple arugula salad dressed in lemon vinaigrette for a peppery contrast. A side of roasted garlic cauliflower wedges or a low‑carb coleslaw also works beautifully. For extra indulgence, drizzle a little sugar‑free ketchup or a dollop of sour cream just before serving.
Storage Info
Leftover Storage
Allow the casserole to cool to room temperature, then cover tightly with plastic wrap or transfer to an airtight container. Refrigerate for up to 4 days. For longer keeping, portion into freezer‑safe bags, label, and freeze for up to 3 months. Thaw overnight in the fridge before reheating for best texture.
Reheating Instructions
Preheat your oven to 350°F (175°C), place a slice in an oven‑safe dish, cover with foil, and heat for 15‑20 minutes until the interior is hot and the cheese melts again. In a microwave, heat a portion on 70 % power for 2‑3 minutes, stirring halfway, and add a splash of heavy cream to revive the sauce.
