Ingredients
Here’s everything you’ll need to create this creamy, high-protein soup.
- 1 tablespoon butter
- 1 large yellow onion, diced
- 2 large carrots, peeled and diced
- 1 stalk celery, diced
- 2 cloves garlic, minced
- 1/4 cup all-purpose flour (substitute gluten-free flour, if needed)
- 1/2 teaspoon smoked paprika
- 3 cups vegetable broth (preferably “not-chicken” style for a richer flavor)
- 4 cups chopped broccoli
- 2 cups 1% milk (or unsweetened almond milk for a dairy-free option)
- 4 oz sharp cheddar cheese, shredded (about 1 cup)
- 1 cup low-fat cottage cheese, blended until smooth
- Salt and pepper to taste
Optional Add-Ins
- Pinch of cayenne pepper for heat.
- Chopped cauliflower for added veggies.
Step-by-Step Directions
Follow these simple steps to create your creamy High Protein Broccoli Cheddar Soup.
- Sauté the Vegetables
- Melt the butter in a large pot over medium heat. Add the diced onion, carrots, and celery. Sauté for about 10 minutes, stirring frequently, until the vegetables are softened.
- Add Garlic and Spices
- Stir in the minced garlic and cook for 1 minute until fragrant. Sprinkle the smoked paprika and flour over the vegetables, stirring to coat. Cook for an additional minute to remove the raw flour taste.
- Incorporate the Broth and Broccoli
- Slowly pour in the vegetable broth while stirring to prevent lumps. Add the chopped broccoli, bring the mixture to a simmer, and cook for 8–9 minutes, or until the broccoli is tender.
- Add Milk and Cheese
- Reduce the heat to low. Stir in the milk, blended cottage cheese, and shredded cheddar cheese. Stir gently until the cheese is melted and fully incorporated. Be careful not to let the soup boil, as high heat can cause the milk to curdle.
- Blend for Creaminess
- For a smoother texture, transfer 1 cup of the soup to a blender and blend until creamy. Return the blended soup to the pot and stir to combine. Alternatively, use an immersion blender to gently blend a portion of the soup, leaving some chunks intact for texture.
- Season and Serve
- Taste the soup and adjust with salt and pepper as needed. Serve warm with your favorite toppings or sides (suggestions coming in Part 2!).

Recipe Notes and Variations
- Thickness: For a thinner soup, add an extra cup of broth or milk until you reach the desired consistency.
- Cheese Options: Sharp cheddar provides a bold flavor, but Gruyère or Monterey Jack can also work well.
- Protein Boost: Stir in cooked shredded chicken or chickpeas for even more protein.

Common Mistakes and How to Avoid Them
Even simple recipes can go wrong without a few precautions. Avoid these common pitfalls when making this soup:
- Curdling the Milk and Cheese
- Mistake: Adding dairy over high heat can cause curdling.
- Solution: Always lower the heat before incorporating milk and cheese, and stir constantly to combine.
- Soup Too Thick or Too Thin
- Mistake: Ending up with soup that’s either overly dense or watery.
- Solution: For thicker soup, simmer a bit longer to reduce liquid. To thin, add more broth or milk gradually until the desired consistency is achieved.
- Lumps in the Soup
- Mistake: Improperly mixing flour with vegetables or adding liquids too quickly.
- Solution: Whisk liquids in gradually and stir continuously to avoid clumping.
- Underseasoning
- Mistake: The soup tastes bland or doesn’t have enough depth.
- Solution: Season gradually and taste as you go. Salt enhances the cheese and vegetable flavors.
- Overcooking the Broccoli
- Mistake: Broccoli turning mushy or losing its vibrant green color.
- Solution: Cook only until tender (8–9 minutes) and avoid over-simmering.

Recipe Tips for Perfect High Protein Broccoli Cheddar Soup
Follow these tips to make your soup extra delicious:
- Blending Techniques
- For a perfectly creamy texture, use an immersion blender directly in the pot. If using a standard blender, blend in small batches and allow steam to escape to avoid pressure buildup.
- Boost the Protein Even More
- Add a handful of cooked, shredded chicken or a can of white beans to increase the protein content further without altering the flavor profile.
- Cheese Options
- Sharp cheddar is the classic choice, but you can experiment with Gruyère, Monterey Jack, or even a touch of blue cheese for a more complex flavor.
- Customizing the Soup
- For a spicy kick, add a pinch of cayenne pepper or red chili flakes.
- Stir in cooked quinoa or brown rice for a heartier soup.
- Toss in a handful of baby spinach or kale at the end for extra greens.
Storage and Reheating Instructions
This soup is perfect for meal prep and stores well. Here’s how to keep it fresh:
- Refrigerator
- Store the soup in an airtight container for up to 4 days.
- Reheat gently over low heat on the stovetop or in the microwave, stirring occasionally to prevent curdling.
