This easy dinner dish can go from prep to table in under 30 minutes. Made with Tilapia fillets, a creamy sauce, cheese, fresh spinach, and cherry red tomatoes, every bite is an explosion of flavor. It's no wonder how it became such a huge favorite around here.
Preheat oven to 450 degrees Fand grease inside of a 9x13 baking dish.
In the bottom of the baking dish, lay 3 handfuls of clean spinach leaves.
Lay the tilapia fillets over the top of the butter, avoiding as much overlap as you can. Some is okay and unavoidable, but less overlap is best.
In a small bowl, mix together the mayo, sour cream, and seasonings.
Spread this mixture over the top of the tilapia fillets evenly with a rubber spatula.
Sprinkle the shredded cheese over the top of the creamy mixture. Top with the halved cherry tomatoes.
Bake at 450 degrees F for 20 minutes or until internal tilapia temperature reaches 145 degrees F with an instant read thermometer.
You can use frozen or thawed tilapia fillets but I recommend having them be at least partially thawed before use. Frozen will work fine but may require a few additional minutes in the oven to come to the proper temperature.
