How to Make High Protein Broccoli Cheddar Soup
Phase 1: Start with the Base
- Melt the butter in a large pot over medium heat.
- Add the onion, carrot, and celery; cook for 10 minutes, stirring frequently until softened.
- Add the garlic and cook for one more minute until fragrant.
Phase 2: Build the Soup
- Sprinkle in smoked paprika and flour, stirring for one minute until vegetables are coated.
- Slowly pour in the vegetable broth while stirring, then add the chopped broccoli. Bring to a simmer.
- Simmer the broccoli for 8–9 minutes, or until tender.
Phase 3: Finish with Creaminess
- Add milk and cook over low heat until the soup is warm, but avoid boiling to prevent curdling.
- Stir in blended cottage cheese and shredded cheddar, and mix until completely melted.
- Blend one cup of the soup in a blender, allowing steam to escape through the vent, and return to the pot (or use an immersion blender for partial blending).
- Taste and season with salt and pepper if necessary.

Pro Tips & Troubleshooting
Pro Tips
- Prep Ahead: Chop broccoli and vegetables a day in advance for quicker cooking.
- Enhanced Flavor: Use roasted garlic instead of fresh garlic for a deeper flavor.
- Blending: Use an immersion blender for convenience.
- Consistency Control: Blend more or less soup depending on your preferred texture.
- Don’t Boil: Keep heat low when adding milk and cheese to avoid curdling.
- Cheese Quality: Use freshly shredded cheese for smoother results.
Common Mistakes to Avoid
- Overcooking Broccoli: It becomes mushy and loses flavor—aim for tender but still vibrant.
- Skipping the Flour: It’s essential for thickening the soup.
- Adding Cheese on High Heat: This causes the cheese to clump; always add cheese slowly on low heat.
- Inadequate Blending: Carelessly blending leaves chunks and affects consistency.
