How to Make Grilled Cheese and Tomato Soup Casserole
-
Preheat your oven to 350°F (175°C). This ensures that your casserole cooks evenly and achieves that perfect golden brown finish.
-
Mix the reduced-fat cream cheese with dried basil in a small bowl until creamy. Spread this flavorful mixture on half of the bread slices for that delicious, cheesy base.
-
Layer the part-skim mozzarella cheese on the cream cheese-spread slices, then top with the remaining bread slices. Butter the outsides generously to create that irresistible crispy crust.
-
Arrange your prepared sandwiches in a greased 13×9-inch baking dish. This allows for ample space for the flavors to meld together beautifully.
-
Combine tomato paste, minced garlic, salt, pepper, and the remaining dried basil in a saucepan. Cook for 1 minute over medium heat, then gradually whisk in the milk until the mixture is bubbling. Simmer for 4-5 minutes until thickened.
-
Whisk the large eggs in a large bowl, then mix in about a third of the hot tomato soup mixture. This step tempers the eggs, preventing them from scrambling when combined.
-
Pour the combined soup mixture over the sandwiches, making sure the bread absorbs the liquid. The more flavor, the better!
-
Sprinkle shredded cheese over the top and bake uncovered for 25-30 minutes, or until the casserole is golden brown. The anticipation will be worth it!
-
Rest the casserole for 10 minutes before serving to allow the flavors to settle and make it easier to slice.
Optional: Serve with a sprinkle of fresh basil for a delightful pop of color and flavor.

Grilled Cheese and Tomato Soup Casserole Recipe FAQs
What type of bread works best for the casserole?
The best breads for this casserole are Italian, sourdough, or rye. I recommend using day-old bread, as it absorbs the soup mixture better and helps prevent sogginess, creating a perfectly textured casserole.
How should I store leftover casserole?
You can store leftovers in an airtight container in the refrigerator for up to 3-4 days. Just reheat individual portions in the microwave, or for a crispier texture, pop them in the oven until warmed through.

What can I do if my casserole turns out soggy?
If you find the casserole too wet after baking, the key is to allow it to sit for a longer time, which helps some of the moisture evaporate. You can also bake it uncovered for an additional 5-10 minutes to help achieve that golden, crispy finish.
Is this casserole suitable for kids with dietary restrictions?
You can easily customize it to be allergy-friendly. For dairy-free versions, substitute the cheese with plant-based options and use non-dairy milk. Always check labels to avoid allergens, such as gluten in the bread or nuts in some cheese alternatives.
