Ingredients for Broccoli Cheese Soup
- Unsalted butter (3 tablespoons): Adds richness (olive oil works too).
- Yellow onion (1 medium, chopped): Builds sweet flavor.
- Garlic (2 cloves, minced): Adds cozy depth.
- Potato (1 medium, peeled and chopped): Natural thickener for creamy texture.
- Low-sodium vegetable broth (4 cups): Keeps it vegetarian and balanced.
- Broccoli florets (5–6 cups): The star (frozen florets work in a pinch).
- Salt and black pepper: Essential for flavor.
- Cheddar cheese, shredded (2 cups): Makes it cheesy and comforting (use sharp cheddar for the most flavor).
- Dijon mustard (1 teaspoon, optional): Tiny amount, big flavor boost.
- Lemon juice (1–2 teaspoons, optional): Brightens and balances the cheese.
Broccoli Cheese Soup Recipe (Step-by-Step)
- 1. Sauté onion in butter over medium heat for 6–8 minutes, until soft and lightly golden. Add garlic and cook 30 seconds until fragrant.
- 2. Simmer by adding potato, vegetable broth, 1/2 teaspoon salt, and a few turns of pepper. Bring to a boil, then reduce to a gentle simmer for 10 minutes.
- 3. Add broccoli florets and simmer 8–10 minutes, until the broccoli is bright green and fork-tender.
- 4. Blend carefully until smooth and creamy. (You can blend all of it, or blend about half if you like more broccoli pieces.)
- 5. Melt the cheese: Turn the heat to low and stir in cheddar a handful at a time until melted. Don’t boil after adding cheese—gentle heat keeps it smooth.
- 6. Finish with Dijon mustard and a small squeeze of lemon if using. Taste and add more salt and pepper if needed. If it’s too thick, whisk in a splash of broth until silky.
Tips for Perfect Broccoli Cheese Soup
- Use sharp cheddar: Stronger flavor means you can use less.
- Shred your own cheese: Pre-shredded cheese can melt grainy.
- Keep heat low after cheese: Boiling can make the soup separate.
- Blend to your liking: Smooth, chunky, or somewhere in between.
- Thin when reheating: Add a splash of broth to bring back the creamy texture.
Variations & Substitutions
- Make it spicy: Add a pinch of cayenne or smoked paprika.
- Add more veggies: Carrots or cauliflower blend in nicely.
- Make it extra cheesy: Stir in 1/2 cup more cheddar at the end.
- Dairy-free version: Use olive oil and a dairy-free cheddar-style shreds (melt slowly).
- Add protein: Stir in white beans before blending for a thicker, filling soup.
- Turn leftovers into sauce: Spoon over baked potatoes or steamed rice.
Storing & Reheating
- Fridge: Store in an airtight container for 4 days.
- Freezer: Freeze up to 2 months (cheese soups can change texture a bit, but it still tastes great).
- Reheat: Warm over low heat, stirring often. Add broth as needed. Avoid boiling.
Serving Suggestions & Pairings
- Crusty bread or garlic toast
- Simple side salad
- Roasted chickpeas for crunch
- Baked potato or sweet potato on the side
- Meal prep lunch with bread and fruit
