Tomato Soup with Cheese and Onion Toast

A Simple Yet Satisfying Classic with a Gourmet Twist

Pairing rich, warm tomato soup with crispy, cheesy onion toast is a timeless comfort meal. This version elevates the dish with golden-broiled cheddar cheese and caramelized onion flavors on buttery toast, making it perfect for a cozy lunch or quick dinner.

Ingredients Overview

Tomato Soup: Use your favorite canned tomato soup or make your own for a fresher flavor.
Cheddar Cheese: Shredded cheddar provides a gooey, savory topping for the toast. Choose sharp cheddar for extra flavor.
Onion: Thinly sliced onions add a sweet, caramelized note that complements the tomato soup perfectly.
Bread: Use sturdy slices like sourdough or rustic white bread for the best texture.
Butter: Adds richness and helps the toast achieve a golden, crispy crust.

Step-by-Step Cooking Instructions

Step 1: Prepare the Tomato Soup

Pour the tomato soup into a medium-sized pot and heat over medium heat. Stir occasionally to prevent scorching and warm until it’s piping hot. Keep covered to retain heat while you prepare the toast.

Step 2: Preheat the Broiler

Set your oven broiler to high. Arrange a rack in the middle to prevent the toast from burning while ensuring even melting.

Step 3: Assemble the Cheese and Onion Toast

Spread butter on one side of each bread slice, ensuring full coverage for even browning. Place the buttered side down on a baking sheet. Top each slice with a generous layer of shredded cheddar cheese, then scatter the sliced onions over the cheese.

Step 4: Broil to Perfection

Place the baking sheet under the broiler and watch closely. Broil for 3-5 minutes, or until the cheese is melted, bubbly, and golden brown. The onions should soften slightly but retain a touch of crunch for texture.

Step 5: Serve and Enjoy

Ladle the hot tomato soup into bowls and serve alongside the cheese and onion toast. For an extra treat, dip the toast into the soup for the ultimate combination of flavors and textures.

Tips for a Seamless Cooking Experience

Upgrade the Soup: Stir in a splash of cream, a dollop of pesto, or a pinch of red pepper flakes to elevate the tomato soup’s flavor.
Toast Alternatives: Swap cheddar for mozzarella or Gruyère for a different cheesy profile.
Layer Onions Evenly: Ensure the onion slices are evenly distributed for consistent caramelization.
Keep an Eye on the Broiler: Broilers can burn food quickly, so don’t step away during this step.
Serve Immediately: Toast is best served fresh and hot to enjoy the melty cheese and crisp edges.

Storage and Reheating Tips

Storage: Store leftover tomato soup in an airtight container in the refrigerator for up to 4 days. Cheese toast is best enjoyed fresh but can be stored for up to 2 days in a sealed container.
Reheating: Reheat soup on the stovetop or in the microwave until hot. To reheat toast, warm it in a toaster oven or under the broiler to revive its crispiness.
