Baked Tomatoes Rockefeller starts with thick tomato slices, each topped with a mixture of cooked spinach, sautéed onions, garlic, and Parmesan.
Seasoned breadcrumbs go into the spinach mixture and over the top. The recipe makes 12 servings and takes 30 minutes from start to finish.
Before you start
Butter the baking dish, cut the tomatoes into thick slices, and lightly beat the eggs. Set aside the breadcrumbs for both the spinach mixture and the topping.
Ingredient notes
- Chopped spinach: Cook it according to the package directions before mixing it with the eggs and seasonings.
- Seasoned dry breadcrumbs: Divide the breadcrumbs before mixing. Use 1 cup in the spinach mixture and save the rest for the topping.
- Tomatoes: Cut the tomatoes into 12 thick slices so each serving has its own base for the spinach topping.

Tips for success
Take the sautéed onions and garlic off the heat before mixing them into the cooked spinach.

Use a food thermometer to check that the center of the spinach-and-egg topping reaches 160°F (71°C) before serving, following FDA guidance for dishes containing eggs.
