Ingredients:

• For the Aromatics and Base:
  • 2 tablespoons unsalted butter or olive oil
  • 1 large yellow onion, finely diced
  • 2 cloves garlic, minced
  • 2 medium carrots, peeled and finely diced (about 1 cup)
  • 2 stalks celery, finely diced (optional, but adds depth)
• For the Vegetables:
  • 4-5 cups fresh broccoli florets, chopped into bite-sized pieces (about 1.5 lbs of broccoli crowns)
• For the Liquids and Seasoning:
  • 4 cups (32 oz) low-sodium chicken broth or vegetable broth
  • 1 teaspoon Dijon mustard (secret ingredient for depth!)
  • 1/2 teaspoon dried thyme
  • 1/4 teaspoon ground black pepper, plus more to taste
  • 1/2 teaspoon salt, plus more to taste
  • Pinch of nutmeg (optional, but highly recommended for dairy-based soups)
• For the Creaminess and Cheese:
  • 1 cup half-and-half or heavy cream (room temperature is best to prevent curdling)
  • 2 cups (about 8 oz) sharp cheddar cheese, freshly shredded (don’t use pre-shredded – it melts poorly!)
  • 1/2 cup cream cheese, softened (optional, for extra richness and thickness)
• For Thickening (Optional, if desired):
  • 2 tablespoons cornstarch mixed with 2 tablespoons cold water (a slurry)

Preparing Your Instant Pot for the Best Broccoli Cheddar Soup Experience

1. First things first, make sure your Instant Pot is clean and ready to go. Gather all your ingredients and do your mise en place – that’s a fancy chef term for having everything prepped and ready before you start cooking. For this particular Instant Pot Broccoli Cheddar Soup, having all your vegetables diced and cheese shredded will make the cooking process seamless and enjoyable. Trust me, it makes a huge difference, especially when you’re moving quickly between steps.
2. Initiate the Sauté Function: Press the “Sauté” button on your Instant Pot. Ensure it’s on the “Normal” or “More” setting if your model offers different heat levels. We want a good heat to properly sauté our aromatics. Add the butter or olive oil to the inner pot and allow it to melt and heat up for about 1-2 minutes until shimmering. This initial step is vital for building a rich flavor base for our Instant Pot Broccoli Cheddar Soup.
3. Sauté the Aromatics: Add the finely diced yellow onion to the hot fat in the Instant Pot. Stir frequently with a wooden spoon or heat-proof spatula. Cook the onions for about 4-5 minutes, or until they become translucent and fragrant. You don’t want them to brown too much; we’re just softening them to release their sweet flavors. This gentle sauté ensures a mellow, sweet foundation for the Instant Pot Broccoli Cheddar Soup.
4. Introduce Carrots and Celery: Next, add the finely diced carrots and celery (if using) to the pot. Continue to sauté for another 3-4 minutes, stirring occasionally. This helps to soften them slightly and brings out their natural sweetness, contributing significantly to the overall depth of flavor in your Instant Pot Broccoli Cheddar Soup.
5. Garlic’s Moment: Now, add the minced garlic to the pot. Stir it in well and cook for just about 1 minute until it becomes fragrant. Be careful not to burn the garlic, as burnt garlic can turn bitter and ruin the delicate flavors of our Instant Pot Broccoli Cheddar Soup. The goal here is to infuse the oil with that lovely garlic aroma.
6. Deglazing the Pot (Crucial Step!): This is a very important step to prevent the dreaded “Burn” error on your Instant Pot. Pour about 1/2 cup of the chicken or vegetable broth into the pot. Use your wooden spoon to scrape up any browned bits stuck to the bottom of the pot. These bits are packed with flavor, and scraping them up not only enhances the soup but also ensures even heating and prevents scorching during the pressure cooking cycle. Make sure the bottom is completely clean before moving on to adding the remaining ingredients for your Instant Pot Broccoli Cheddar Soup.

Building the Flavor and Pressure Cooking Your Broccoli Cheddar Soup

7. Adding Broccoli and Seasonings: Now that the Instant Pot is deglazed, add the remaining chicken or vegetable broth, the chopped broccoli florets, Dijon mustard, dried thyme, salt, pepper, and the pinch of nutmeg (if using). Stir everything gently to combine. Try to keep the broccoli mostly submerged in the liquid, though it’s okay if some florets are peeking out. This is the core of our Instant Pot Broccoli Cheddar Soup, so ensure all those delicious flavors are well distributed.
8. Pressure Cooking Time: Secure the lid on your Instant Pot, making sure the sealing ring is properly in place. Turn the steam release valve to the “Sealing” position. Select the “Manual” or “Pressure Cook” button and set the cooking time to 5 minutes on High Pressure. For perfectly tender but not mushy broccoli, 5 minutes is ideal for this Instant Pot Broccoli Cheddar Soup.
9. Natural Pressure Release (NPR): Once the cooking cycle is complete, the Instant Pot will beep and switch to “Keep Warm.” Allow the pressure to release naturally for at least 10 minutes. This is called a Natural Pressure Release (NPR) and it’s important for two reasons: it allows the soup to settle and helps prevent a sudden burst of hot liquid when you open the lid, and it continues to gently cook the vegetables, deepening their flavor and texture. After 10 minutes, carefully turn the steam release valve to the “Venting” position to release any remaining pressure. Once the floating pin drops, it is safe to open the lid.

Achieving the Perfect Creamy & Cheesy Texture for Your Instant Pot Broccoli Cheddar Soup

10. Partial Blending for Texture: At this stage, your Instant Pot Broccoli Cheddar Soup will look a bit rustic. For that classic creamy restaurant-style texture, we’re going to blend it. You have a few options here:
    • Immersion Blender: This is my preferred method for convenience. Carefully place an immersion blender into the pot and blend until you reach your desired consistency. I like to blend about 2/3 of the soup, leaving some small chunks of broccoli and carrots for texture. This gives you a lovely creamy base with satisfying bites of vegetables in your Instant Pot Broccoli Cheddar Soup.
    • Regular Blender: If you don’t have an immersion blender, carefully transfer about half of the soup to a regular blender. Make sure to only fill it halfway, and remove the center cap from the blender lid (covering the opening with a kitchen towel) to allow steam to escape. Blend until smooth, then return the blended portion to the Instant Pot. Repeat with another portion if desired. Be very cautious when blending hot liquids.

    Important note: If you prefer a completely smooth soup, feel free to blend the entire contents until velvety. It’s all about personal preference for your Instant Pot Broccoli Cheddar Soup!

11. Tempering and Adding Creaminess: Turn off the “Keep Warm” function if it’s still on. In a separate bowl, whisk together the room temperature half-and-half or heavy cream with the softened cream cheese (if using) until smooth. This helps prevent the cream from curdling when added to the hot soup. Gradually whisk this cream mixture into the soup in the Instant Pot. Stir continuously until it’s fully incorporated and the soup looks creamy.
12. Incorporating the Cheddar Cheese: This is the moment for the “Cheddar” in our Instant Pot Broccoli Cheddar Soup! Add the freshly shredded sharp cheddar cheese to the soup, a handful at a time, stirring constantly until each batch is completely melted and smooth before adding more. Do NOT let the soup boil once the cheese and cream are added, as this can cause the cheese to separate and become grainy. The residual heat from the soup is enough to melt the cheese beautifully. This gentle melting process is key to achieving a smooth, luxurious Instant Pot Broccoli Cheddar Soup.

Final Adjustments and Serving Your Delicious Instant Pot Broccoli Cheddar Soup

13. Adjusting Consistency (Optional): If your soup is thinner than you’d like, you can thicken it further. In a small bowl, whisk together 2 tablespoons of cornstarch with 2 tablespoons of cold water until smooth to create a slurry. With the Instant Pot on the “Sauté” function (on low heat) or “Keep Warm,” gradually whisk the cornstarch slurry into the soup. Stir continuously for 1-2 minutes until the soup thickens to your desired consistency. Remember, it will thicken a bit more as it cools.
14. Taste and Adjust Seasoning: Now is the time to taste your magnificent Instant Pot Broccoli Cheddar Soup. Adjust salt, pepper, or any other seasoning to your liking. Sometimes a little extra salt or a dash of black pepper can really make the flavors pop.
15. Serving Your Creation: Ladle the hot Instant Pot Broccoli Cheddar Soup into bowls. For an extra special touch, you can garnish each bowl with a sprinkle of extra shredded cheddar cheese, a dollop of sour cream, some crispy bacon bits, or a few croutons. This soup is wonderfully comforting on its own, but also pairs beautifully with a crusty bread or a fresh green salad. Enjoy the fruits of your labor – this homemade Instant Pot Broccoli Cheddar Soup is truly a treat!
16. Storing Leftovers: Any leftover Instant Pot Broccoli Cheddar Soup can be stored in an airtight container in the refrigerator for up to 3-4 days. To reheat, gently warm on the stovetop over low heat, stirring frequently, or in the microwave. If it thickens too much, you can add a splash of broth or milk to reach your desired consistency. Avoid boiling when reheating, especially with the cheese and cream, to maintain its smooth texture.

Instant Pot Broccoli Cheddar Soup

is the undisputed champion.

Now, let’s talk about making this soup truly your own. While it’s absolutely perfect as is, I always encourage a little culinary creativity! For serving, consider pairing it with a crusty artisan bread, a warm pretzel roll, or some homemade garlic croutons – perfect for soaking up every last drop of that creamy goodness. A simple side salad can also round out the meal beautifully, offering a refreshing counterpoint to the richness of the soup. And for toppings? Don’t be shy! A generous sprinkle of extra shredded cheddar, a dollop of sour cream or Greek yogurt, crispy bacon bits, a scattering of fresh chives or parsley, or even a dash of red pepper flakes for a subtle kick can elevate your bowl to new heights. You could also try some toasted pumpkin seeds or sunflower seeds for a lovely textural contrast.

Looking to switch things up entirely? This recipe is wonderfully adaptable. For a veggie boost, why not add some finely shredded carrots along with the broccoli? Or perhaps a handful of spinach or chopped cauliflower? If you’re a cheese connoisseur, experiment with different cheeses like smoked gouda for a deeper flavor, Gruyère for nutty notes, or even a white cheddar for a sharper tang. For those seeking a lighter option, you can swap out some of the heavy cream for half-and-half or even milk, though you might lose a touch of that luxurious mouthfeel. On the flip side, if you want an even thicker, richer soup, a little extra cream or a spoonful of cream cheese can do wonders. And for my plant-based friends, you can easily adapt this by using vegetable broth, a plant-based milk or cashew cream, and your favorite dairy-free cheddar alternative. The possibilities are truly endless, and each variation promises a delicious adventure.

I genuinely hope this recipe inspires you to get into your kitchen and experience the magic for yourself. There’s a special kind of satisfaction that comes from creating something so delicious from scratch, especially when it’s as fuss-free and rewarding as this soup. Don’t let another chilly evening pass you by without a bowl of this creamy, dreamy goodness in hand. I am confident that you will love it.
