Ingredients You’ll Need for Broccoli Cheddar Soup

Before we dive into the cooking process, let’s take a look at the ingredients that will transform mere kitchen staples into a heartwarming meal. Below is what you’ll need, including some valuable substitutions and shortcuts.

Essentials

4 tablespoons unsalted butter – Butter adds rich flavor and is the base for our soup. Unsalted is best so you can control the saltiness.
1 medium yellow onion, chopped – Onion adds a sweet and savory depth of flavor.
1/2 teaspoon sea salt – Enhances the flavors of the other ingredients.
Freshly ground black pepper to taste – Adds a bit of heat and complexity.
3 garlic cloves, chopped – Fresh garlic lends a robust flavor.
1/4 cup all-purpose flour – This will thicken our soup and create a lovely, creamy texture.
2 cups whole milk or unsweetened almond milk – For the creamiest result, use whole milk. Almond milk works too for a dairy-free option.
2 cups vegetable broth – A flavorful base that complements the other ingredients.
3 cups chopped broccoli florets – The star of the recipe; fresh broccoli is essential for taste.
1 large carrot, julienned or finely chopped – Adds a hint of sweetness and color.
1/2 teaspoon Dijon mustard – Just a touch for a flavorful kick.
8 ounces shredded cheddar cheese (about 2 heaping cups) – Cheddar is what makes this soup indulgent and comforting.

Optional Add-Ons

Homemade croutons – Perfect for adding a crunchy texture on top of your soup.

Substitutions and Shortcuts

Dairy-Free: Use unsweetened almond milk and a dairy-free cheese option for a vegan variant.
Frozen Broccoli: If fresh broccoli isn’t available, frozen works just fine—just thaw and drain before adding.
Onion Powder: In a pinch, onion powder can replace fresh onion, but I recommend using fresh for the best flavor.

How to Make Broccoli Cheddar Soup Step-by-Step

Now, let’s get into the nitty-gritty of making this delightful Broccoli Cheddar Soup.

Step 1: Sautéing the Aromatics

Start by melting 4 tablespoons of unsalted butter in a large pot or Dutch oven over medium heat. Once the butter is melted and bubbly, toss in the chopped onion, sea salt, and freshly ground black pepper. Cook while stirring for about 5 minutes until the onion softens and becomes translucent. Then, stir in the chopped garlic and cook for an additional minute, allowing the garlic to release its fragrant aroma.

Next, sprinkle in the 1/4 cup of all-purpose flour. This is a crucial step, as the flour will help thicken your soup. Whisk continuously for 1 to 2 minutes, allowing the flour to turn golden and cook through.

Step 2: Adding the Liquid

Once your flour is golden and fragrant, slowly pour in the 2 cups of whole milk (or unsweetened almond milk). This will form the creamy base for your soup. Whisk continuously as you pour to prevent any clumps from forming. Next, add in 2 cups of vegetable broth, stirring to combine.

Step 3: Bringing It All Together

Now it’s time for the stars of the show! Add in the 3 cups of chopped broccoli florets, julienned carrot, and 1/2 teaspoon of Dijon mustard. Stir everything together and bring the mixture to a gentle simmer. Allow it to bubble away for about 15 to 20 minutes, or until the broccoli is tender and bright green.

Step 4: Melting the Cheese

Once the broccoli is cooked through, it’s time to incorporate the 8 ounces of shredded cheddar cheese. Gradually add the cheese, stirring after each addition. Keep stirring until all the cheese is melted and the soup achieves that dreamy, creamy consistency. Take a moment to taste your creation; you might want to add a bit more salt or pepper to suit your palate.

Step 5: Garnishing and Serving

If you want to get fancy, top your soup with homemade croutons for an extra crunch. Simply gather some day-old bread, cube it, toss it with olive oil, garlic powder, and a sprinkle of salt, then bake until golden. Serve your Broccoli Cheddar Soup hot, and watch as everyone gathers around for a cozy meal.

Common Mistakes to Avoid When Making Broccoli Cheddar Soup

Even the most seasoned cooks can make mistakes when whipping up this sumptuous soup. Here are some pitfalls to avoid:

Using the Wrong Cheese

Not all cheeses are created equal. While cheddar is the traditional choice for Broccoli Cheddar Soup, using a low-quality or pre-shredded cheese can lead to a grainy texture. Opt for a good quality block of cheese and shred it yourself for the creamiest result.

Overcooking the Broccoli

While you want the broccoli tender, overcooking it can lead to a mushy texture. Aim for a bright green color—after all, you want it to look as good as it tastes!

Neglecting to Season

Don’t forget to taste and season throughout the cooking process. Adding salt and pepper gradually will allow the flavors to deepen, making for a more delicious soup.

Not Whisking Properly

When adding the flour and milk, incorporate them slowly while whisking continuously. This helps to avoid lumps and ensures a silky finish.

Serving Suggestions for Broccoli Cheddar Soup

Looking to elevate your serving game? Here are a few ideas to complement your Broccoli Cheddar Soup:

Perfect Pairings

Crusty Bread: Pair your soup with a slice of crusty sourdough or a warm baguette for dipping. The contrast of the creamy soup with warm, fresh bread is unbeatable.
Salad: A light, crisp salad, such as a simple arugula salad with lemon vinaigrette, balances the richness of the soup beautifully.
Sandwich: This soup pairs wonderfully with a classic grilled cheese or a turkey sandwich, creating a nostalgic lunch reminiscent of childhood favorites.

Creative Toppings

Fresh Herbs: A sprinkle of fresh thyme or chives adds a burst of color and a mild flavor that pairs well with the cheese and broccoli.
Spices: Try adding a sprinkle of cayenne pepper for a spicy kick, or some smoked paprika for a hint of smokiness.

Make It a Meal

Protein Boost: You can stir in cooked shredded chicken or white beans for added protein, making this a more filling meal.

Pro-Level Tips for When You’re Ready

Once you’re comfortable with the basics of Broccoli Cheddar Soup, here are some pro-level tips to take your cooking to the next level:

Add More Veggies

Amp up the nutrition by adding other vegetables, such as spinach, kale, or cauliflower. You can also throw in some peas for a touch of sweetness and color.

Make It Ahead

Broccoli Cheddar Soup holds up beautifully in the fridge. You can make it a day ahead and reheat it when you’re ready. In fact, the flavors tend to develop even more overnight!

Freeze for Later

This soup freezes remarkably well. Simply let it cool completely and store it in airtight containers. When you’re ready for a cozy meal, thaw it overnight in the fridge and reheat on the stove.
