Ingredients to make sauce for baked tilapia:

- 2 cloves garlic, crushed
- 1/2 cup sour cream
- 1 tsp old bay seasoning
- 1/2 tsp adobo seasoning
- 1/4 tsp black pepper
- 1/4 tsp salt
NOTE: Use as much spinach as you can pack into your baking dish because spinach does shrink quite a bit.
1. First, pack spinach onto the bottom of a baking dish. Top with butter slices and layer the fish fillets over the top
.
2. Then, combine the sauce ingredients and evenly spread over the top of the casserole. Finally, sprinkle with cheese and bake in a preheated to 500 degrees F oven for 10 minutes.
Note: The thicker the fish fillets the longer you may need to bake your fish.
