- Broccoli- One large head of broccoli is equal to about 5 cups of roughly chopped broccoli florets.

- Onion- Adds a wonderful savory flavor that complements the rest of the vegetables.
- Garlic- For a delicious garlic flavor.
- Chicken Stock- Always use homemade chicken stock whenever possible for the richest flavor. Otherwise, opt for high-quality, low-sodium chicken stock.
- Butter- Sautéing the vegetables in butter adds a rich and buttery flavor to the soup.
- Heavy Cream- Just a touch of heavy cream gives this asparagus broccoli soup a velvety texture.
- Kosher Salt- For flavor. The amount of salt you add will depend on your taste preference and the amount of salt in your chicken stock. Always add salt in increments and taste for seasoning.
- Black Pepper- Use freshly ground black pepper for the best flavor.
Substitutions and Variations
Here are a few ways you can try customizing this broccoli asparagus soup recipe to fit your diet and taste preferences.
- Broccoli- Swap fresh broccoli for frozen broccoli if preferred. Cauliflower can also be used in place of the broccoli.
- Asparagus- Try fresh peas in place of the asparagus. Or leave the asparagus out and use all broccoli.
- Russet Potato- Yukon Gold potatoes, red potatoes, or baby potatoes can be substituted for russet potatoes.
- Onion- Replace fresh onion with one tablespoon of onion powder. Leeks, shallots, and green onions also make great onion substitutes.
- Garlic- Use one teaspoon of garlic powder in place of fresh garlic cloves.
- Chicken Stock- Swap chicken stock for vegetable broth for a vegetarian option.
- Butter- Use any fat you typically cook with. Olive oil, bacon fat, or tallow are all excellent choices.
- Heavy Cream- Substitute heavy cream with half and half, full-fat coconut milk, or whole milk.
- Dairy-Free- Swap the butter for olive oil and the heavy cream for full-fat coconut milk.
- Vegan- To make vegan broccoli asparagus soup, replace the butter with olive oil, the heavy cream with coconut milk, and the chicken stock with vegetable stock.
- Low-Carb- Substitute the russet potato for cauliflower for a low-carb version of this broccoli asparagus potato soup. Keep in mind, the soup won't be as thick if you make this swap.
- Cheesy- Add a little shredded cheddar cheese, grated parmesan cheese, or crumbled goat cheese to make it extra creamy and cheesy.
- Spicy- A few shakes of red pepper flakes or cayenne pepper powder can bring a little heat to this soup. Or add diced jalapeño with the rest of the sautéed vegetables.
- Lemony- Grate some lemon zest over the finished soup or add a squeeze of fresh lemon juice for a pop of bright citrus flavor.
Step by Step Instructions
Here is how to make creamy broccoli asparagus soup.
Step 1: Sauté the vegetables. Melt butter in a large pot over medium heat. Add the broccoli, asparagus, onion, garlic, kosher salt, and ground black pepper to the pot. Cook for 5-7 minutes or until the vegetables are softened and beginning to brown.
Step 2: Cook the potatoes. Pour in the chicken stock and add the diced potatoes. Stir well and bring to a boil. Reduce heat to low and simmer for 10-15 minutes or until the potatoes are fork-tender.
Step 3: Purée the soup. Remove the pot from the heat. Use an immersion blender or regular blender to purée the soup to a smooth and creamy consistency. If the soup seems thin, continue simmering until it reaches your desired thickness. Keep in mind that it will thicken up as it cools.
Step 4: Add heavy cream. Pour in the heavy cream and stir until well combined. Serve with crusty bread or croutons if desired.
Tips for Success
- Cut the vegetables small. Chop the vegetables small so they cook quickly and evenly. Smaller vegetables are also easier to blend.
- Use an immersion blender. The easiest way to make puréed soup is with an immersion blender.
- Or purée in batches with a regular blender. If you don't have an immersion blender, carefully transfer soup into a regular blender and purée it in batches.
- Add more liquid to thin. If the soup is too thick after puréeing, add an extra splash of chicken stock, vegetable stock, or water.
- Simmer to thicken. On the other hand, if your soup seems too thin, continue simmering it until it reaches your desired consistency.
- Serve with fun toppings. Top your asparagus broccoli soup with homemade croutons, pesto, or grated parmesan cheese.
What to Serve With Broccoli Asparagus Soup
Broccoli asparagus soup is light and simple, yet hearty and satisfying at the same time.
I love dipping Crusty Sourdough Bread in this soup for lunch, especially this Jalapeño Cheddar Sourdough Bread. It's also delicious paired with a light and flavorful salad like this Kale Crunch Salad.
Storage and Reheating
How to Store
- Refrigerator- Store leftovers in an airtight container in the refrigerator for up to 4 days.
- Freezer- For longer storage, broccoli asparagus soup can be stored in the freezer. Place individual or family-sized portions of leftover soup in freezer-safe containers and freeze for 3-6 months.
How to Reheat
- Stovetop- Pour soup into a saucepan and set it over low heat. Heat the soup, stirring occasionally, until it just begins to simmer. Remove from heat and serve immediately.
- Microwave- Place a serving of soup in a microwave-safe bowl. Heat on HIGH in 30-second intervals, stirring between each, until the soup is fully warmed through.
Get a head start on preparation by chopping the broccoli, asparagus, onion, and garlic up to 3 days in advance. I don't recommend cutting the potatoes ahead of time because they'll turn brown.
Alternatively, prepare the entire dish and store it in the refrigerator for up to 2 days before serving. Then, simply reheat it on the stovetop.
