Ingredients
This recipe makes 6 generous servings.
- 4 tablespoons unsalted butter
- 1 medium yellow onion, finely diced
- 3 cloves garlic, minced
- 1/4 cup all-purpose flour
- 3 cups whole milk
- 2 cups chicken broth or vegetable broth
- 1 pound fresh broccoli, cut into small florets
- 2 medium carrots, peeled and diced small
- 1/2 teaspoon dried thyme
- 1/4 teaspoon ground nutmeg
- 1 bay leaf
- 2 cups sharp cheddar cheese, freshly grated
- 1/2 cup heavy cream
- 1 teaspoon salt, plus more to taste
- 1/2 teaspoon black pepper
- 1/4 teaspoon cayenne pepper (optional)
Step-by-Step Instructions
- Melt the butter in a large, heavy-bottomed pot or Dutch oven over medium heat until it begins to foam gently.
- Add the diced onion to the melted butter and cook for approximately 5 minutes, stirring occasionally, until the onion becomes soft and translucent.
- Stir in the minced garlic and cook for another 30 seconds until fragrant, being careful not to let it brown.
- Sprinkle the flour over the onion mixture and stir constantly for about 2 minutes to create a roux, which will thicken your soup beautifully.
- Gradually pour in the milk while whisking continuously to prevent lumps from forming in your soup base.
- Add the chicken broth slowly, continuing to whisk until the mixture is completely smooth and well combined.
- Bring the liquid to a gentle simmer over medium heat, stirring occasionally to prevent sticking on the bottom.
- Add the broccoli florets, diced carrots, dried thyme, ground nutmeg, and bay leaf to the pot.
- Reduce the heat to medium-low and let the soup simmer for 15 to 20 minutes, until the vegetables are tender when pierced with a fork.
- Remove the bay leaf from the soup and discard it carefully.
- Turn the heat to low and gradually add the grated cheddar cheese in small handfuls, stirring after each addition until completely melted and smooth.
- Pour in the heavy cream and stir gently to incorporate it throughout the soup.
- Season with salt, black pepper, and cayenne pepper if using, then taste and adjust the seasoning as needed.
- Continue cooking on low heat for another 5 minutes to allow all the flavors to meld together perfectly.
- Remove from heat and let the soup rest for about 5 minutes before serving to allow it to thicken slightly.
Serving Tips
Serve this hearty soup piping hot in warm bowls for the ultimate comfort food experience. For added texture and flavor, consider topping each bowl with extra shredded cheddar cheese, crispy bacon bits, or homemade croutons. A sprinkle of fresh chives or green onions adds a beautiful pop of color and a mild onion flavor that complements the richness perfectly. This soup pairs wonderfully with crusty sourdough bread, buttery dinner rolls, or a simple side salad dressed with vinaigrette. Moreover, it makes an excellent starter for holiday dinners or special occasions when served in smaller portions. Consider offering hot sauce or red pepper flakes on the side for guests who prefer a bit of heat. The soup also works beautifully as a main course when accompanied by a grilled cheese sandwich for the ultimate comfort food combination.
Storage Tips
Allow the soup to cool completely before transferring it to airtight containers for storage. In the refrigerator, properly stored broccoli cheddar soup will stay fresh for up to 4 days. When reheating, do so gently over low heat on the stovetop, stirring frequently to prevent the cheese from separating. You may need to add a splash of milk or broth to restore the creamy consistency, as the soup tends to thicken when chilled.
For freezing, transfer cooled soup to freezer-safe containers, leaving about an inch of space at the top for expansion. The soup can be frozen for up to 3 months, though the texture may change slightly upon thawing. To thaw, move the container to the refrigerator overnight, then reheat gently on the stovetop. Avoid microwaving at high power, as this can cause the cheese to become grainy and separate from the base.
Helpful Notes
Cheese Selection: Always use freshly grated cheese rather than pre-shredded varieties, which contain anti-caking agents that prevent smooth melting. Sharp cheddar provides the best flavor, but you can experiment with a combination of medium cheddar and Gruyere for added depth.
Broccoli Preparation: Cut the broccoli florets into uniform, bite-sized pieces to ensure even cooking. Don’t discard the stems; peel off the tough outer layer and dice the tender inside to add to your soup for extra nutrition and less waste.
Soup Consistency: If you prefer a completely smooth soup, use an immersion blender to puree a portion of the vegetables before adding the cheese. Alternatively, leave it chunky for more texture and visual appeal.
Preventing Grainy Cheese: Never let the soup boil once you’ve added the cheese, as high heat causes the proteins to seize and become grainy. Keep the heat low and stir gently for the silkiest texture.
Flour Substitution: For a gluten-free version, replace the all-purpose flour with an equal amount of rice flour or cornstarch mixed with a little cold water before adding.
Broth Options: Vegetable broth works perfectly for a vegetarian version, while chicken broth adds a deeper, more savory flavor profile. For extra richness, consider using bone broth instead.
Chef Tips
To elevate this soup to restaurant quality, toast the flour slightly longer when making your roux until it develops a light golden color and nutty aroma. This simple step adds incredible depth to the overall flavor profile. Additionally, reserve some of the blanched broccoli florets to add at the very end, which provides a beautiful contrast in texture and keeps the soup looking fresh and vibrant.
Frequently Asked Questions
Can I use frozen broccoli instead of fresh? Yes, frozen broccoli works well in this recipe; just add it directly to the pot without thawing and extend the cooking time by about 5 minutes.
What can I substitute for heavy cream? Half-and-half or additional whole milk can replace heavy cream, though the soup will be slightly less rich and creamy in texture.
Why did my cheese become stringy or grainy? This happens when the soup gets too hot after adding cheese; always keep the heat on low and add cheese gradually while stirring constantly.
Can I make this soup in a slow cooker? Absolutely; cook the vegetables in broth on low for 4-6 hours, then stir in the cheese and cream during the last 30 minutes.
How can I make this soup thicker? Blend a portion of the soup with an immersion blender, add more cheese, or make a slurry with cornstarch and water to stir in while simmering.
