Make the Soup Base
- Melt butter in a large Dutch oven or heavy-bottomed pot over medium heat. Add the onion, carrots, and celery. Sauté for 6-8 minutes, until softened. Add the minced garlic and cook for another minute until fragrant.
- Sprinkle the all-purpose flour over the vegetables and stir continuously for 1 minute to cook out the raw flour taste. This creates the roux.
- Slowly whisk in the broth, a little at a time, to prevent lumps. Once all the broth is incorporated and smooth, stir in the half-and-half.
- Bring the soup to a gentle simmer, then reduce the heat to medium-low. Add the broccoli florets, Dijon mustard, and nutmeg. Let it cook, stirring occasionally, for 10-12 minutes, or until the broccoli is tender-crisp.
Prepare the Dumpling Dough
- While the soup simmers, prepare the dumplings. In a medium mixing bowl, whisk together the flour, baking powder, and salt.
- Cut in the cold butter using a pastry blender or your fingertips until the mixture resembles coarse crumbs. Stir in the 1 cup of grated cheddar cheese and chopped chives.
- Pour in the milk and stir with a fork just until a shaggy, moist dough forms. Do not overmix.
Cook the Dumplings & Finish
- Stir the 1 1/2 cups of grated cheddar cheese into the soup until it's completely melted and the soup is smooth. Season generously with salt and pepper to taste. Ensure the soup is at a gentle, steady simmer, not a rolling boil.
- Drop rounded tablespoons of the dumpling dough into the simmering soup, spacing them out. You should have about 10-12 dumplings.
- Cover the pot and cook for 12-15 minutes without lifting the lid. The dumplings will steam and puff up. They are done when a toothpick inserted into the center of a dumpling comes out clean.
- Serve the broccoli cheddar dumpling soup immediately, garnished with extra chives or cheddar cheese if desired.
Notes
For the creamiest, smoothest soup, always grate your own cheese from a block. Pre-shredded cheeses contain anti-caking agents that can make the soup gritty. For tender dumplings, be careful not to overwork the dough. Store leftovers in an airtight container in the refrigerator for up to 3 days; note that the dumplings will absorb more liquid and soften over time.
