Core Ingredients:

- 2 tbsp butter – For that golden, buttery crisp on top.
Flavor Boosters (Optional but Worth It):
- 1 tsp garlic powder – Adds depth.
- ½ tsp dried basil or oregano – Herbs make it restaurant-worthy.
- Pinch of red pepper flakes – For a subtle kick.
Fresh Additions (Herbs, Garlic, Optional Veggies)
Want to sneak in extra flavor or nutrients? Toss in:
- 1 minced garlic clove – Because fresh garlic > powder.
- ¼ cup diced onions or sun-dried tomatoes – For texture and sweetness.
- Handful of fresh basil or parsley – Brightens up the dish.

Step-by-Step Grilled Cheese Casserole Instructions
Prep Work (Preheating, Greasing the Dish)
- Preheat your oven to 375°F (190°C) – This ensures even cooking.
- Grease your baking dish – Use butter or non-stick spray for easy serving later.
Layering the Casserole (Bread, Cheese, Soup Mixture)

- Whisk the soup mixture – In a bowl, combine tomato soup, milk, garlic powder, and herbs until smooth. Pour over the bread and cheese.
Key Tip: Press the bread down gently so it soaks up the liquid like a savory bread pudding.
Baking to Golden Perfection (Time & Temperature Tips)
- Cover with foil and bake for 20 minutes – This lets the bread absorb the liquid.
- Uncover, add remaining cheese, and bake for 10–15 more minutes – Until the top is bubbly and golden brown.
The Finishing Touch (Broiling for a Crispy Top)

Serving Suggestion: Let it cool for 5 minutes so the layers set. Then, scoop and enjoy with a side salad or garlic bread.

Grilled Cheese Casserole FAQs Answered
Absolutely! While canned soup keeps things quick and easy, homemade tomato soup adds a fresh, vibrant flavor to your Tomato Soup and Grilled Cheese Casserole. Just make sure it’s thick enough about the consistency of canned condensed soup. If it’s too thin, simmer it longer or add a tablespoon of tomato paste.
The secret? Stale bread and proper layering:
Use day-old bread (it absorbs liquid without turning mushy).
Don’t oversaturate pour the soup mixture just until coated, not swimming.
Bake uncovered for the last 10-15 minutes to crisp up the top.
For the perfect texture, go with:
French bread or sourdough – Sturdy and flavorful.
Texas toast – Extra thick for a hearty bite.
Whole grain – For a nuttier taste (just toast it slightly first).
Avoid super-soft sandwich bread, it turns to mush too quickly!
Oh yes meat makes everything better! Try:
Italian sausage (browned first) for a spicy kick.
Pro Tip: If adding meat, reduce the salt in the soup mixture since most cured meats are already salty.
