How to Make Broccoli Cauliflower Soup

Step 1: Prep All Your Veggies

Start by peeling the onion, carrots, and garlic cloves. Dice your onion and mince the garlic, then move on to grating the carrots (or cheat a little with pre-shredded). When it comes to broccoli and cauliflower, don’t just settle for big florets—chop everything into smaller pieces, stems included. This way, you get tiny bursts of flavor and texture in every spoonful, which makes the soup feel extra special.

Step 2: Grate the Cheese and Measure Everything

Freshly grating your sharp cheddar cheese makes a huge difference—bagged shreds just don’t melt as well. Measure out all your other ingredients and keep them close at hand; it’ll make the cooking process fast, smooth, and stress-free.

Step 3: Sauté Onion and Carrot

Heat up 1 tablespoon of butter in a large pot or Dutch oven over medium-high heat. Add your chopped onion and grated carrot and cook, stirring occasionally, until everything softens and the kitchen smells amazing.

Step 4: Add Garlic and More Butter

Turn the heat down to medium and toss in the garlic along with the rest of the butter. Let the garlic cook for a minute or so, just until it’s fragrant, but don’t let it brown. This infuses the butter and veggies with a mellow garlicky flavor.

Step 5: Stir in Flour

Sprinkle the flour over the veggies and stir to coat. Keep stirring for about 30 seconds, letting the flour cook just enough to lose its raw edge. This sets you up for a perfectly smooth, thick soup.

Step 6: Add Broccoli, Cauliflower, and Broth

Next, add your chopped broccoli and cauliflower along with your broth of choice. Don’t walk away—stir constantly as the soup heats up and starts to thicken, preventing any sticking or lumps while the flavors begin to meld.

Step 7: Season and Simmer

Drop in the garlic powder, sea salt, and black pepper, stirring to combine. Turn the heat down to its lowest setting, cover the pot, and let everything gently simmer for 10 to 15 minutes. When the broccoli and cauliflower are fork-tender, you’re golden.

Step 8: Stir in Cream and Cheese

Take the pot off the heat and add the heavy cream (or half cream, half milk). Gradually stir in your grated cheddar in a few batches, letting each handful melt in completely before adding the next. The soup will turn irresistibly creamy and cheesy right before your eyes.

Step 9: Ladle and Top

Your Broccoli Cauliflower Soup is ready to serve! Ladle it into bowls and go wild with your favorite toppings, like more cheddar, crisp bacon bits, a scattering of green onions, or a handful of broccoli sprouts. Cozy up and enjoy every bite.

How to Serve Broccoli Cauliflower Soup

Garnishes

This soup loves a little customization, so don’t be shy! Extra sharp cheddar adds a gooey finish, while bacon bits (regular or veggie) bring salty crunch. Try scattering sliced green onions for a fresh kick or topping with broccoli sprouts for a bit of flair and extra nutrition. Each option gives your Broccoli Cauliflower Soup a tasty twist and an inviting look.

Side Dishes

Pair Broccoli Cauliflower Soup with crusty artisan bread for dunking, a crisp green salad, or even cheesy garlic bread sticks. The creaminess of the soup is a perfect match for something to dip, but it’s also light enough to enjoy with a fresh, simple side.

Creative Ways to Present

For a fun dinner party or casual lunch, serve Broccoli Cauliflower Soup in bread bowls or small mason jars for a rustic vibe. You can also portion it into shot glasses for an elegant appetizer, or top each bowl with a swirl of cream and microgreens for restaurant-style presentation. The bold colors and silky texture always earn compliments!

Make Ahead and Storage

Storing Leftovers

Leftover Broccoli Cauliflower Soup keeps beautifully in the fridge. Simply let it cool to room temperature, then store it in an airtight container. It’ll stay fresh for up to four days, ready for a quick meal whenever the craving strikes.

Freezing

The soup can be frozen, though the texture might change a little because of the dairy. Cool completely before ladling into freezer-safe containers, leaving some space for expansion. It’s best to reheat gently for the creamiest results after thawing.

Reheating

Warm Broccoli Cauliflower Soup on the stovetop over low heat, stirring frequently. If it thickens up too much, add a splash of broth or milk to loosen it. You can also microwave it in short bursts, stirring between each, for a quick lunch.

FAQs

Can I make Broccoli Cauliflower Soup vegetarian or vegan?

Absolutely! Use vegetable broth to keep it vegetarian, and swap in your favorite plant-based milk and vegan cheddar for a completely vegan soup. The result is still rich, creamy, and deeply flavorful.

Can I blend the soup for a smoother texture?

Certainly! For a velvety finish, use an immersion blender directly in the pot to puree all or part of the soup. You can also blend just half the soup and mix it back in for the best of both creamy and chunky worlds.

What’s the best cheese to use?

Sharp cheddar is classic for Broccoli Cauliflower Soup, but you can experiment with Gruyère or a little Parmesan for added complexity and a punch of umami. Always grate cheese fresh for smooth melting!

Can I use frozen veggies?

Definitely—frozen broccoli and cauliflower are fantastic in a pinch. There’s no need to thaw first; just add directly to the pot and adjust the simmering time a bit if needed.

How do I thicken the soup if it’s too thin?

If your soup is a bit runny, let it simmer uncovered for a few extra minutes to reduce and naturally thicken. Alternatively, mix a teaspoon of flour with a splash of water, stir it in, and cook until your desired consistency is achieved.
