🧾 Ingredients: Everything for One Cozy, Cheesy Bake

The beauty of this Tomato Soup and Grilled Cheese Casserole lies in its simplicity. With just a few familiar ingredients from your pantry and fridge, you can whip up a warm, nostalgic dish that feels both elevated and deeply homey. Each layer brings something comforting — from the buttery toast to the melty cheese and rich, velvety tomato soup base.

🍞 Bread & Butter: The Golden Foundation

• 8 slices of white or sourdough bread – Choose thick, hearty slices. Sourdough offers a nice tang, while classic white gives that familiar grilled cheese texture.
• 2 tablespoons butter – Spread on each side before toasting or grilling. It helps the bread hold its shape and adds that golden, buttery crunch essential for any good casserole foundation.

For extra flavor, try brushing the bread with garlic-infused butter or toasting it with a sprinkle of Italian seasoning.

🧀 Cheeses: The Gooey Heart of the Casserole

• 3 cups shredded sharp cheddar cheese – This brings that iconic grilled cheese flavor and melts beautifully.
• 2 cups shredded mozzarella (optional) – For stretch and creaminess, mozzarella is your melty best friend. Want something bolder? Try gouda or pepper jack.

Mix and match cheeses based on your taste — this recipe is flexible and fun to personalize.

🍅 Soup Base: Rich, Creamy, and Cozy

• 2 cans (10.5 oz each) condensed tomato soup – Any favorite brand works. Look for a version with basil or roasted garlic for added depth.
• 1 cup milk or heavy cream – Cream adds richness and smooths out the acidity of the tomatoes.
• 1 teaspoon garlic powder
• 1 teaspoon onion powder
• Salt and freshly cracked black pepper to taste

Combine and warm these ingredients gently before pouring over the bread and cheese layers. It’s the flavor glue that ties the dish together.

🌿 Garnish & Optional Add-Ins

• Fresh basil or parsley – Sprinkle on top before serving to brighten the flavors and add a touch of color.
• Grated Parmesan or red pepper flakes – Add before baking for a salty bite or a hint of heat. You can also toss in baby spinach, cooked bacon, or sautéed mushrooms for added dimension.

This combination makes the Tomato Soup and Grilled Cheese Casserole the kind of dish that hits every note — creamy, cheesy, crispy, and savory.

👨‍🍳 Instructions: How to Make Tomato Soup and Grilled Cheese Casserole

Making Tomato Soup and Grilled Cheese Casserole is as satisfying as it is simple. This creamy, cheesy casserole turns the classic comfort food duo into a baked dish you’ll crave again and again. In just five easy steps, you’ll create something that’s hearty enough for dinner, cozy enough for snow days, and nostalgic enough to remind you of childhood.

Each layer — crispy bread, gooey cheese, and rich tomato soup — bakes together into one comforting bite after another. Let’s break it down.

🔥 Step 1: Toast the Bread

Start by creating the foundation of your Tomato Soup and Grilled Cheese Casserole:

• Butter both sides of 8 slices of bread.
• Toast in a skillet over medium heat until golden on both sides.
• Let them cool slightly, then slice into bite-sized cubes.

👉 Toasting the bread first prevents sogginess and adds that irresistible grilled cheese crunch you love.

🍅 Step 2: Make the Tomato Cream Base

While your bread cools:

• In a medium saucepan, combine:
  • 2 cans of condensed tomato soup
  • 1 cup milk or heavy cream
  • 1 tsp garlic powder
  • 1 tsp onion powder
  • Salt and black pepper to taste
• Whisk together and simmer over low heat for 5–10 minutes, until warm and slightly thickened.

✨ Want more control over the flavor? Use your own homemade tomato soup as the base, just make sure it’s thick and creamy for best results.

🧀 Step 3: Assemble the Casserole

Now the magic happens:

• Preheat oven to 375°F.
• Lightly grease a 9×13 inch casserole dish.
• Layer half the toasted bread cubes on the bottom.
• Sprinkle with half the shredded cheeses.
• Pour half the tomato soup mixture over.
• Repeat with remaining bread, cheese, and soup.
• Top with extra cheese if you love it gooey.

This layering technique ensures every bite is packed with cheesy, savory, tomato-rich goodness.

⏲️ Step 4: Bake

• Cover with foil and bake for 20 minutes.
• Remove foil and bake uncovered for another 10 minutes, until bubbly and golden on top.
• Optional: Broil for 2–3 minutes to get that extra crispy cheese crust.

🧑‍🍳 The result? A Tomato Soup and Grilled Cheese Casserole with toasted edges, melty center, and layers that just melt in your mouth.

🌿 Step 5: Serve & Garnish

• Let the casserole cool for 5–10 minutes.
• Garnish with chopped fresh basil or parsley.
• Serve warm with a light salad or roasted vegetables for a complete, balanced meal.
