Broccoli Soup au Gratin

Rated as 4.33 out of 5 Stars

"This soup is a delicious way to use broccoli. The recipe needs some tweaking due to the thickness of it and how the cheesy crouton went soggy too quickly - next time I'd use small croutons instead of one big one."

  1. Melt 1 tablespoon butter in a large pot over medium heat; add onion. Cook and stir until onion turns translucent, 5 to 6 minutes. Add garlic; stir for 1 minute. Pour in broth; bring to a simmer over high heat.
  2. Separate florets from heads of broccoli. Cut large florets in half. Cut stems in half and cut into 1/2-inch pieces. Add broccoli to simmering broth. Cover and cook until broccoli softens slightly, 2 to 3 minutes. Reduce heat to medium-low; simmer, stirring occasionally, until broccoli is very tender, about 10 minutes. Remove from heat.
  3. Blend broccoli with an immersion blender into a very smooth puree. Stir in cream, salt, pepper, nutmeg, and cayenne. Return soup to medium-low heat; cook until cream is heated through, about 5 minutes.
  4. Preheat oven to 375 degrees F (190 degrees C). Line a rimmed baking sheet with aluminum foil.
  5. Butter both sides of bread with remaining 1 tablespoon butter and place on the lined baking sheet.
  6. Bake bread in the preheated oven, turning halfway through, until toasted and crisp, 4 to 5 minutes.
  7. Place 6 oven-proof soup crocks on the foil-lined baking sheet. Ladle soup into the crocks, filling almost to the top. Place 1 piece of toasted bread in each crock; cover with Cheddar cheese.
  8. Set oven rack about 6 inches from the heat source and preheat the oven's broiler.
  9. Place baking sheet under broiler and broil until cheese is browned and bubbly, 3 to 4 minutes.


  • Cook's Notes:
  • If soup seems too thick, be sure to adjust with more broth if need be. If you pass the soup through a fine mesh strainer, the soup will achieve a finer texture.
  • If you do not have an immersion blender, you can blend the soup in batches in a traditional blender; use caution with hot broth.
  • Substitute Gruyere cheese for the Cheddar if desired, or use a combination of the two.
