High Protein Broccoli Cheese Soup
This is the kind of soup you make on a chilly night when you want something comforting but still balanced. It’s rich and cheesy, loaded with broccoli, and boosted with extra protein to keep you full longer. No complicated methods, no tricky ingredients—just solid, everyday cooking.
If you love classic broccoli cheddar soup but want it to work harder for you, this version hits the sweet spot. It’s great for meal prep, family dinners, or quick lunches all week.
What Makes This Special
- High protein without losing comfort: We use Greek yogurt and cottage cheese (or protein-rich milk) to add protein while keeping that silky, cheesy texture.
- Balanced creaminess: A small amount of butter and cheddar delivers flavor, while blended broccoli and dairy add body without heavy cream.
- Meal-prep friendly: Reheats well and freezes nicely with a couple of easy tweaks.
- Flexible and budget-friendly: Use fresh or frozen broccoli, and swap ingredients based on what you have.
Ingredients
- 2 tablespoons unsalted butter
- 1 tablespoon olive oil
- 1 medium yellow onion, finely chopped
- 2 medium carrots, diced small
- 3 cloves garlic, minced
- 5 cups broccoli florets and stems, chopped (fresh or frozen)
- 4 cups low-sodium chicken broth or vegetable broth
- 1 cup 2% or whole milk (or unsweetened protein milk)
- 1 cup low-fat cottage cheese
- 1 cup plain 2% Greek yogurt, room temperature
- 1 ½ cups sharp cheddar cheese, freshly grated
- 2 tablespoons cornstarch (optional, for extra thickness)
- 1 teaspoon Dijon mustard
- ½ teaspoon smoked paprika
- ¼ teaspoon nutmeg (optional but great with cheddar)
- Salt and black pepper, to taste
- Chili flakes or hot sauce, to taste (optional)
High Protein Broccoli Cheese Soup
- Warm a large pot over medium heat. Add the butter and olive oil.
When the butter melts, add the onion and carrots. Cook for 5–6 minutes, stirring often, until the onion turns translucent and the carrots start to soften.
- Stir in the garlic and cook for 30 seconds, just until fragrant. Do not let it brown.
- Add the chopped broccoli, broth, smoked paprika, nutmeg, and a pinch of salt and pepper.
Bring to a gentle boil, then lower to a simmer. Cook for 10–12 minutes, until the broccoli is very tender.
- While the soup simmers, blend the cottage cheese and milk in a blender until completely smooth. This creates a creamy, high-protein base without heavy cream.
- Optional thickener: Whisk the cornstarch into the milk-cottage cheese mixture until dissolved.
This will give the soup extra body later.
- Use an immersion blender to partially blend the soup in the pot. Leave some small pieces for texture. If you don’t have an immersion blender, transfer half the soup to a blender, blend until smooth, and return it to the pot.
- Lower the heat to medium-low.
Stir in the milk-cottage cheese mixture and the Dijon mustard. Let it warm gently for 2–3 minutes. Do not boil after this point.
- Turn the heat to low.
Add the grated cheddar by the handful, stirring slowly until melted and smooth. Keep the heat gentle to prevent the cheese from separating.
- Remove from heat. Whisk in the Greek yogurt until fully incorporated.
Taste and adjust with more salt, pepper, and chili flakes or hot sauce if you like a kick.
- Let the soup rest for 5 minutes to thicken slightly. Ladle into bowls and garnish with a little extra cheddar, cracked pepper, or a drizzle of olive oil.
Storage Instructions
- Refrigerator: Cool completely, then store in airtight containers for up to 4 days.
- Reheating: Warm gently over low heat on the stove or in the microwave at 50–70% power, stirring occasionally. Avoid boiling to prevent curdling.
- Freezer: This soup freezes well for up to 2 months if you skip the Greek yogurt when cooking.
Add the yogurt after reheating to serve. Thaw overnight in the fridge before reheating.
Benefits of This Recipe
- High in protein: Cottage cheese and Greek yogurt add a significant protein boost without overpowering the cheese flavor.
- Vegetable-forward: A generous amount of broccoli provides fiber, vitamin C, vitamin K, and antioxidants.
- Comfort with balance: You get that cozy, cheesy experience with a lighter approach than traditional cream-heavy versions.
- Adaptable for diets: Easy to make gluten-free (use cornstarch) and vegetarian (use vegetable broth).
- Budget smart: Uses common ingredients and works well with frozen broccoli and pantry staples.
What Not to Do
- Don’t boil after adding dairy: High heat can cause the yogurt and cheese to split or turn grainy.
- Don’t use pre-shredded cheese if you can avoid it: Anti-caking agents can make the soup less smooth. Freshly grated melts better.
- Don’t skip seasoning as you go: Add salt and pepper in stages.
It helps build a well-rounded flavor.
- Don’t over-blend: You want some texture from the broccoli, not a one-note puree.
- Don’t add cold yogurt to hot soup without stirring off the heat: Temper it or remove from heat before mixing to prevent curdling.
Variations You Can Try
- Chicken boost: Stir in 1–2 cups of shredded rotisserie chicken for even more protein.
- Turkey bacon crumble: Top with crisped turkey bacon or pancetta for a smoky finish.
- Cauliflower mix: Swap half the broccoli for cauliflower to change up the flavor and texture.
- Spicy jalapeño cheddar: Add diced jalapeño with the onions and use pepper jack plus cheddar.
- Vegan-ish route: Use plant-based protein milk, a scoop of unflavored pea protein blended with the milk, and a good melting vegan cheddar. Skip the yogurt and cottage cheese, or use unsweetened plant-based yogurt.
- Herb twist: Finish with fresh chives, parsley, or thyme for brightness.
- Lower fat, still creamy: Use reduced-fat cheddar and nonfat Greek yogurt. Keep heat low to prevent separation.
FAQ’s For High Protein Broccoli Cheese Soup
How can I make this even higher in protein?
Blend 1–2 scoops of unflavored whey or pea protein into the milk-cottage cheese mixture before adding to the pot. Add it off the heat and whisk well to avoid clumping. You can also stir in cooked chicken breast or use ultra-filtered milk.
Can I use frozen broccoli?
Yes. Add it straight from frozen and simmer until tender. You may need an extra minute or two, but the result is just as good.
What if I don’t have Greek yogurt?
Use plain skyr or strain regular yogurt through a fine sieve for 20–30 minutes to thicken it. In a pinch, you can add a splash more milk and a bit of extra cheddar, but you’ll lose some protein.
Why did my soup turn grainy?
This usually happens when the soup boils after adding cheese or yogurt, or when using pre-shredded cheese. Keep the heat low, add dairy slowly, and stir gently. Freshly grated cheddar makes a smoother finish.
Can I make this gluten-free?
Yes. The recipe uses cornstarch instead of flour for thickening. Double-check your broth and cheese to ensure they’re gluten-free.
What cheese works best?
Sharp cheddar delivers classic flavor and melts well. For extra melt, combine cheddar with a small amount of Gruyère or Monterey Jack.
How thick should the soup be?
Aim for a smooth, spoon-coating consistency. If it’s too thin, simmer gently to reduce or whisk in a cornstarch slurry. If too thick, loosen with a splash of warm broth or milk.
Final Thoughts
High Protein Broccoli Cheese Soup gives you everything you love about the classic—with more staying power.
