How to Make Tomato Soup & Grilled Cheese Casserole

Prep Work: Start by gathering all your ingredients and preheating your oven to 450°F (230°C). Don’t forget to grease a 9×13-inch baking dish to prevent sticking.
Bread Preparation: Take 6 slices of sourdough bread and spread 2 tablespoons of softened butter on them. Lay them butter-side down on a baking sheet. Additionally, spread cream cheese on the remaining slices, layer with cheddar cheese, and top with the buttered bread slices.
Bake Sandwiches: Bake in the oven for 12-14 minutes, flipping once until the cheese melts and bread is golden. Allow them to cool for 15 minutes, then reduce the oven temperature to 350°F (175°C).
Mix Soup Base: In a large bowl, whisk together the condensed tomato soup, tomato juice, eggs, Italian seasoning, garlic powder, and chopped Roma tomatoes until well combined.
Assemble Casserole: Cut the toasted sandwiches into 1-inch cubes, pour the soup mixture into the prepared dish, and layer the bread cubes on top. Lightly press them to submerge, then sprinkle with shredded Italian blend cheese.
Final Bake: Bake the assembled casserole at 350°F (175°C) until the cheese is bubbly and golden, typically about 25-30 minutes.

Optional: Drizzle with balsamic glaze for a touch of sweetness before serving.

Tomato Soup & Grilled Cheese Casserole Recipe FAQs

How do I choose ripe tomatoes for this recipe?
Absolutely! When selecting Roma tomatoes, look for firm ones that are deep red in color without any dark spots or blemishes. Ripe tomatoes should feel heavy for their size, indicating juiciness. If they’re too soft or shriveled, they’re likely overripe and won’t add the freshness you’re looking for in this casserole.

What is the best way to store leftovers of the casserole?
Very simply! Store leftover Tomato Soup & Grilled Cheese Casserole in an airtight container in the refrigerator. It will last for about 3 days. Just make sure to cool the casserole to room temperature before sealing it; this helps retain moisture and prevents it from becoming soggy.

Can I freeze Tomato Soup & Grilled Cheese Casserole?
Absolutely! To freeze, cut the casserole into individual portions and place them in freezer-safe containers. Ensure they’re tightly sealed to prevent freezer burn. You can freeze it for up to 3 months. When you’re ready to enjoy, thaw it in the fridge overnight, then reheat in the oven at 350°F (175°C) until hot and bubbly, usually about 20-25 minutes.

What if the casserole turns out too dry?
No worries! If your casserole ends up dry, you can enhance its moisture by adding a little more tomato juice next time, or even a splash of milk or cream can work wonders. When baking, it’s crucial to keep an eye on it to ensure it doesn’t overcook; you want a delightful, creamy texture to savor!

Are there any dietary restrictions I should consider?
For sure! If you’re catering to dietary restrictions, consider using gluten-free bread for those who are gluten intolerant. You can also replace cream cheese with a non-dairy alternative to accommodate lactose intolerance. Be sure to check the labels on all pre-packaged ingredients, like tomato soup, for allergens. Each family can tweak the recipe to meet any special dietary needs!
