Warm, satisfying, and deeply flavorful, tomato soup is a cornerstone of home cooking. While many are familiar with the classic pairing of soup and a grilled cheese sandwich, incorporating cheddar bay dumplings directly into the pot creates a more cohesive and hearty meal. This recipe elevates a simple tomato base into a gourmet experience by topping it with fluffy, cheesy biscuits that steam to perfection right in the broth.
Table of Contents
This version of the dish relies on high-quality pantry staples to deliver a rich texture and a balanced flavor profile. By using a specialized biscuit mix for the dumplings, the preparation remains accessible for cooks of all skill levels while ensuring a consistent, delicious result. For those who enjoy exploring various styles of this classic dish, this medieval times tomato bisque soup recipe offers another perspective on achieving a velvety soup texture.
Why This Recipe Works
The success of this dish lies in the contrast between the acidic brightness of the tomatoes and the savory, buttery notes of the dumplings. Using undrained diced tomatoes ensures that the natural juices provide a deep foundation for the broth. The addition of a sweet onion and a touch of sugar helps to mellow the tomatoes, creating a smooth finish that isn’t overly tart.
The dumplings act as both a side dish and a thickener, absorbing some of the savory chicken stock while maintaining a soft, pillowy interior. It is a one-pot meal that provides everything needed for a complete lunch or dinner. If you are a fan of filling, broth-based meals, you might also find inspiration in this ham and bean soup recipe, which focuses on building deep layers of flavor.
Ingredients and Equipment
To achieve the best results, ensure all ingredients are measured accurately before beginning the cooking process.

For the Tomato Soup:
- Canned Diced Tomatoes: 43.5 oz (undrained to preserve all flavorful juices)
- Chicken Stock: 3 cups
- Butter: 2 tablespoons
- Sweet Onion: 1, finely chopped
- All-Purpose Flour: 3 tablespoons
- Sugar: 1 teaspoon
- Coarse Salt: 3/4 teaspoon (kosher salt preferred)
- Ground Black Pepper: 1/4 teaspoon
For the Cheddar Bay Dumplings & Topping:
- Cheddar Bay Biscuit Mix: 1 packet (11 oz)
- Butter: 2 tablespoons (melted, for brushing over the finished dumplings)
- Water: As directed by the biscuit mix package (typically around 1/2 to 3/4 cup)
- Grated Cheddar Cheese: Provided in the mix (or added according to package instructions)
Required Tools:
- Large Dutch oven or heavy-bottomed stockpot
- Whisk
- Wooden spoon or spatula
- Mixing bowl
- Pastry brush
Step-by-Step Instructions
1. Sauté the Aromatics
Place a large pot over medium heat and add the 2 tablespoons of butter. Once the butter has melted and stopped foaming, add the chopped sweet onion. Cook the onion for about 5 to 7 minutes, stirring occasionally. The goal is to reach a translucent and soft state without letting the onions turn brown or crispy.
2. Create the Thickening Base
Sprinkle the 3 tablespoons of all-purpose flour over the softened onions. Stir constantly for about 1 to 2 minutes. This “roux” stage is vital because it cooks out the raw flour taste and will help the soup achieve a slightly thickened, silky body later on.

3. Build the Soup
Slowly pour in the 3 cups of chicken stock while whisking or stirring vigorously to prevent lumps from forming. Once the stock is integrated, add the 43.5 oz of undrained diced tomatoes. Stir in the sugar, coarse salt, and black pepper. Bring the mixture to a gentle boil, then reduce the heat to low. Cover the pot and let it simmer for about 15 minutes to allow the flavors to meld.
4. Prepare the Dumpling Dough
While the soup is simmering, prepare the dumpling dough in a separate mixing bowl. Combine the cheddar bay biscuit mix with the water and cheese as specified on the package instructions. Stir until a soft dough forms. Avoid overworking the dough, as this can lead to dense dumplings.

5. Steam the Dumplings
Remove the lid from the soup pot. Using a tablespoon or a small cookie scoop, drop rounded portions of the dough onto the surface of the simmering soup. Ensure there is a little space between each dumpling. Replace the lid tightly and simmer for 10 to 12 minutes. The steam inside the pot is necessary to cook the dough through.
6. Finish with Melted Butter
Once the dumplings are firm and have risen, turn off the heat. Melt the remaining 2 tablespoons of butter. Using a pastry brush, gently coat the top of each dumpling with the melted butter. If the biscuit mix included a seasoning packet, this can be stirred into the melted butter before brushing.

Tips for Success
- Keep the Lid Closed: It is tempting to check the progress, but lifting the lid lets out the steam required to make the dumplings light and fluffy.
- Texture Preferences: If a smoother soup is preferred, use a blender to process the tomato and onion mixture before adding the dumpling dough.
- Simmer, Don’t Boil: Ensure the soup is at a low simmer when adding the dough. A hard boil can break the dumplings apart before they have a chance to set.
- Consistency Check: If the soup appears too thick after simmering, a small amount of extra chicken stock can be added before the dumpling stage.
Storage and Reheating
Refrigeration
Store any remaining soup and dumplings in an airtight container in the refrigerator for up to three days. Note that the dumplings will continue to soak up the soup liquid as they sit, which results in a thicker consistency the next day.
Reheating
To reheat, place the desired portion in a saucepan over low heat. It may be necessary to add a splash of water or stock to loosen the base. Heat slowly until the center of the dumplings is warm. Microwave reheating is possible but may result in a slightly tougher dumpling texture.
Frequently Asked Questions
1. Can I use water instead of chicken stock? While water can be used, chicken stock provides a much deeper savory flavor that complements the tomatoes.
2. Why are my dumplings falling apart? This usually happens if the soup is boiling too vigorously or if the dough was too wet. Ensure a gentle simmer and accurate measurements.
3. Do I need to drain the tomatoes? No, the juice in the cans contains significant flavor and acidity that is necessary for the soup’s base.
4. Can I add fresh herbs? Fresh basil or parsley can be added to the soup base for extra brightness, though it is not required for the classic flavor.
5. What is the best way to chop the onion? A fine dice is best so that the onion pieces blend into the texture of the tomatoes and flour base.
6. Can I make the soup ahead of time? The soup base can be made ahead, but it is recommended to add and cook the dumplings just before serving for the best texture.
7. Can I use a different brand of biscuit mix? While other mixes work, the specific seasoning in the cheddar bay style mix provides the signature flavor for this recipe.
8. Is the sugar necessary? The sugar helps balance the high acidity found in canned tomatoes. It does not make the soup “sweet” but rather well-rounded.
9. My soup is too thin, what should I do? The dumplings will naturally thicken the soup as they cook. If it is still too thin, simmer uncovered for a few minutes after the dumplings are done.
10. Can I use salted butter? If using salted butter, consider slightly reducing the amount of added coarse salt to prevent the dish from becoming too salty.
