Key Ingredients & Their Roles
- Cauliflower Rice: Forms the base; frozen works well for convenience.
- Cream Cheese: Adds creaminess; can swap for Greek yogurt for a lighter option.
- Chopped Veggies: Boost nutrition; feel free to mix seasonal choices.
- Cheddar Cheese: Provides flavor and melt; sharp cheddar elevates the taste.
How to Make Loaded Cauliflower Rice Casserole
- Preheat your oven to 375°F (190°C). Sauté chopped onions and garlic in a skillet until golden and aromatic, about 4 minutes.
- Add the cauliflower rice to the skillet, stirring well to coat with the sautéed mix. Cook for another 5 minutes until heated through.
- In a large bowl, combine cream cheese, sour cream, and half the cheddar until smooth, then fold in the veggie mix until evenly combined.
- Transfer the mixture to a greased baking dish, top with remaining cheddar, and bake for 25-30 minutes or until bubbly and golden. Let cool for a few minutes before serving.

Pro Tips & Troubleshooting
- When prepping, make sure your cauliflower rice is thawed and drained to avoid excess moisture.
- A common mistake is overcooking the casserole, which can lead to a watery texture; aim for a golden top.
- Add some cooked crumbled bacon or sausage for a savory twist, or use seasonal veggies for freshness.
Storage & Make-Ahead Guide
This casserole can be refrigerated for up to 4 days. If you want to freeze it, store in an airtight container for up to 3 months. Reheat in the oven at 350°F (175°C) for about 20 minutes, or microwave until heated through. I’ve found that leftovers taste just as good, if not better, the next day!
