Ingredients List
Main Ingredients:
- 2 pounds ground beef (80/20 blend for best flavor and fat content)
- 1 large head cauliflower, cut into bite-sized florets (about 6 cups)
- 1 large yellow onion, diced
- 3 cloves garlic, minced
- 8 oz cream cheese, softened
- ½ cup heavy cream
- 1 cup beef broth (sugar-free)
- 2 cups sharp cheddar cheese, shredded (divided)
- 1 cup mozzarella cheese, shredded
- 3 tablespoons butter
Seasonings:
- 2 teaspoons paprika
- 1 teaspoon garlic powder
- 1 teaspoon onion powder
- 1 teaspoon dried thyme
- ½ teaspoon dried rosemary
- 1 teaspoon salt (or to taste)
- ½ teaspoon black pepper
- ¼ teaspoon cayenne pepper (optional)
Fresh Garnishes:
- 3 green onions, sliced
- ¼ cup fresh parsley, chopped
- 2 tablespoons fresh chives, chopped
Keto-Friendly Substitutions:
- Ground turkey or chicken thighs for different protein options
- Broccoli or Brussels sprouts instead of cauliflower
- Coconut cream instead of heavy cream for dairy-sensitive individuals
- Ghee instead of butter for those avoiding dairy
- Different cheese combinations like Gruyère, Gouda, or Parmesan
Make-Ahead Options:
- Frozen cauliflower works great (just thaw and drain well first)
- Pre-shredded cheese saves time but freshly shredded melts better
- Pre-cooked ground beef can be used to cut prep time
Step-by-Step Instructions
- Prepare your workspace (5 minutes): Preheat your oven to 375°F (190°C). Grease a 9×13 inch baking dish with butter. Cut cauliflower into uniform florets and let cream cheese come to room temperature for easier mixing. Time-saver tip: Use a food processor to quickly chop the cauliflower!
- Steam the cauliflower (8 minutes): Steam cauliflower florets until just tender (about 6-8 minutes). They should be fork-tender but not mushy – they’ll continue cooking in the oven. Drain thoroughly and set aside. Pro tip: Pat the cauliflower dry with paper towels to prevent a watery casserole!
- Brown the beef (8 minutes): In a large skillet over medium-high heat, brown the ground beef, breaking it up as it cooks. Don’t drain the fat – that’s liquid gold for keto! Season with salt, pepper, and half of the spice blend. Flavor secret: Let the beef get nice and crispy in spots for extra flavor!
- Sauté aromatics (3 minutes): Push beef to one side of the pan and add diced onion and minced garlic. Cook until fragrant and onion is translucent. Mix everything together and add remaining seasonings.
- Create the creamy base (4 minutes): Reduce heat to medium-low. Add softened cream cheese to the skillet and stir until melted and combined. Slowly pour in heavy cream and beef broth, stirring constantly to create a smooth, creamy sauce. Smooth sauce trick: Whisk continuously to prevent lumps!
- Combine and layer (3 minutes): Add the steamed cauliflower to the beef mixture and gently fold together. Add 1 cup of the cheddar cheese and all the mozzarella, stirring until melted and well combined. Taste and adjust seasoning as needed.
- Assemble casserole (2 minutes): Transfer the mixture to your prepared baking dish, spreading it evenly. Top with the remaining 1 cup of cheddar cheese, creating an even layer for that perfect golden top.
- Bake to perfection (25 minutes): Bake uncovered for 20-25 minutes until the top is golden brown and bubbly, and the edges are slightly crispy. Visual cue: The cheese should be melted and golden with some darker spots for extra flavor!
- Rest and garnish (5 minutes): Let the casserole rest for 5 minutes before serving – this helps it set up and makes serving easier. Garnish with fresh green onions, parsley, and chives for a pop of color and freshness.
