Step‑by‑Step Instructions for Broccoli Cauliflower Soup
Step 1: Prep Veggies
Begin by prepping your vegetables for the Broccoli Cauliflower Soup. Dice 1 small yellow onion, grate 2 large carrots, and mince 2-3 cloves of garlic. Chop the broccoli and cauliflower into smaller florets and pieces to ensure they're tender when cooked. This will take about 10 minutes, but the exciting aroma of your fresh vegetables will inspire your cooking journey.
Step 2: Sauté Vegetables
In a large pot, melt 1 tablespoon of unsalted butter over medium-high heat. Once the butter is bubbly, add the diced onion and grated carrots. Sauté for about 5-7 minutes until the vegetables are tender and the onion is translucent. Lower the heat and stir in the minced garlic and the remaining butter, cooking for another 1-2 minutes until fragrant, transforming your kitchen into a delightful aroma zone.
Step 3: Make Roux
With the sautéed mixture bubbling gently, sprinkle 3 tablespoons of flour over the vegetables. Stir vigorously for 20-30 seconds to form a roux that coats the veggies; this will thicken your Broccoli Cauliflower Soup. Keep an eye on the color: you want it to remain light, avoiding any browning, as it will keep your soup creamy.
Step 4: Add Broccoli & Cauliflower
Now it’s time to introduce the main players! Stir in the chopped broccoli, cauliflower, and 3 cups of low-sodium vegetable broth. Increase the heat slightly and bring the mixture to a gentle simmer. Allow the soup to bubble away for about 10-15 minutes, stirring occasionally until the vegetables are tender and vibrant in color, creating a feast for the eyes.
Step 5: Finish Soup
Remove the pot from the heat and add ½ cup of heavy cream for a smooth consistency. Gradually stir in 6 ounces of freshly grated sharp cheddar cheese, ensuring it melts beautifully into the soup. The creamy texture should be rich and velvety, inviting you to dive right in.
Step 6: Serve
Ladle your luscious Broccoli Cauliflower Soup into warm bowls and consider topping with your favorite garnishes, such as croutons or freshly cracked pepper. Feel free to serve it alongside crusty bread for a comforting meal. As you savor each spoonful, enjoy the cozy warmth you’ve crafted from scratch!

Reheating Tips: When reheating leftovers, do it gently over low heat, stirring frequently to maintain the creamy texture and prevent separation.

Healthy Substitutions: For a lighter version, consider substituting heavy cream with cream cheese or Greek yogurt, which adds creaminess while reducing fat.

Broccoli Cauliflower Soup Recipe FAQs
How do I select the best broccoli and cauliflower for the soup?

What’s the best way to store leftover Broccoli Cauliflower Soup?
You can store any leftovers in an airtight container in the fridge for 3 to 4 days. Make sure it’s completely cooled before sealing. I often make a double batch for quick meals throughout the week! When ready to enjoy, reheat gently on the stove to maintain that rich, creamy texture.
