Tips for Best Results
Roast Cauliflower Well – It adds flavor and avoids soggy texture
Use a Thick Marinara – Thin sauces can make the casserole watery
Layer Thoughtfully – Spread toppings evenly for flavor in every bite
Add Protein – Ground chicken, sausage, or diced cooked meat works great
Broil for Crisp Top – Add 2 minutes under broiler for a golden cheese crust

Serving Suggestions
With a side salad – Adds freshness and crunch
Garlic bread (low-carb or regular) – For classic pizza vibes
Zucchini noodles or spaghetti squash – For extra veggies
