Notes

Thaw and drain cauliflower rice thoroughly to prevent a watery casserole.

Brown mushrooms until their moisture evaporates.

Freshly grated cheese melts more smoothly.

Mushroom base and Spike seasoning are optional.

Add bell peppers, spinach, or green beans after cooking off excess moisture.

For a crunchy topping, add seasoned breadcrumbs before baking.

Refrigerate leftovers in an airtight container for 3–4 days.

Freeze portions for 2–3 months for best quality.

Thaw in the refrigerator and reheat leftovers to 165°F (74°C).
