Ingredients
- 2 cups shredded rotisserie chicken or shredded cooked chicken breasts

- 4 cups chicken broth (or 4 cups of water and 4 tsp of Better than Bouillon Chicken Base)
- 1/4 cup butter

How to Make Instant Pot Broccoli Cheddar Chicken Soup
Step 1. Begin by turning on your Instant Pot and selecting the sauté function at the ‘more’ setting. Melt 1 tablespoon of butter and watch for it to foam slightly; this indicates it’s ready. Once melted, toss in your diced onion, sautéing for about three minutes until the onion turns translucent. This step enhances the aroma and flavor foundation for your soup.
Step 2. Now it’s time to elevate the soup with more colors and nutrients. Add in the shredded carrots and coarsely chopped broccoli, followed by the garlic powder and chicken broth. Stir everything together gently so that the vegetables are coated. Cover the Instant Pot and lock the lid firmly in place. Ensure the valve is set to ‘sealing’ to build pressure properly.
Step 3. Set the pot to the manual or pressure cook setting and let it cook for one minute. While the Instant Pot does its work, prepare your roux in a large stockpot. Melt 1/4 cup of butter over medium heat, then whisk in the flour until combined. This mixture will help thicken your soup later.
Step 4. As the Instant Pot finishes cooking, warm your milk in a separate saucepan on low heat. This step will help incorporate it more smoothly into the soup. When the timer beeps, do a quick release of the pressure and carefully remove the lid. You’ll notice the fresh vegetables will have softened nicely.
Step 5. Set the Instant Pot back to the sauté function. Take one cup of broth from the pot and whisk it into the roux until smooth, then slowly pour this mixture back into the pot while stirring. Keep an eye on it as it thickens to ensure a creamy texture without lumps.
Step 6. Continue by stirring in the warmed milk and half of the grated sharp cheddar until melted and integrated. This will lend a delightful creaminess to the soup. Once melted, add the remaining cheese, ensuring it completely blends in for a luxurious finish.
Step 7. Introduce your shredded chicken into the simmering mixture, seasoning with salt and pepper to taste. For those who enjoy a thicker consistency, remove a ladle of the soup and mix it with the cornstarch to make a slurry. Return this back to the pot while stirring until you reach your desired thickness.
Step 8. Finally, ladle the soup into bowls, savoring the sight of vibrant colors and creamy texture. Serve it warm, and enjoy the soothing flavors that come together in this comforting meal.

Serving Ideas for Instant Pot Broccoli Cheddar Chicken Soup
This creamy soup is hearty enough to stand alone, but it pairs beautifully with crusty bread or a simple green salad for a well-rounded meal. If you have leftovers, consider packing them in lunch containers for easy reheating during the week. The flavors can deepen, making the second day just as enjoyable.

Practical Tips for Instant Pot Broccoli Cheddar Chicken Soup
- Use pre-shredded cheese for faster melting and easier incorporation.
- Adding a splash of hot sauce can elevate the flavor without overpowering the base.
- If you prefer a smoother soup, consider blending a portion of it after cooking, which can add a nice twist to the texture.
- Adjust the thickness by adding more or less cornstarch based on your preference.
- Always taste before serving; a pinch more salt or pepper can enhance the overall flavor.
- To save on dishes, consider warming the milk directly in the Instant Pot on a low setting after pressure cooking.
Common Mistakes to Avoid
- Overcooking chicken: If rotisserie chicken is left in the pot too long, it can become dry. Since it’s already cooked, just add it to the soup towards the end.
- Not melting the cheese properly: If cheese isn’t added gradually, it can clump together. Stir in the cheese in batches, ensuring it melts smoothly into the soup.
- Using too much cornstarch: Adding excess cornstarch can result in an overly thick or gummy consistency. Start with small amounts and gradually increase if necessary.
- Poor seasoning: If you forget to adjust salt and pepper, the final flavor might be bland. Always taste your soup before serving to make necessary adjustments.
- Skipping the sauté step: Sauteing the onion and vegetables builds a rich flavor. Skipping this step might leave the soup one-dimensional.
- Closing the valve incorrectly: If the valve isn’t set to ‘sealing,’ the pot won’t build pressure. Always check this before starting the cooking cycle for the desired results.
Simple Variations
- For added nutrition, consider throwing in some other vegetables like peas or corn during the pressure cooking step.
- If you prefer a different flavor profile, experiment with different varieties of cheddar cheese; a medium or even a garlic herb cheese can add extra touches.
- For a spicier kick, add a pinch of red pepper flakes to the sautéed onions.
Storage & Reheating
You can store leftover soup in the fridge for about a week. Allow it to cool down to room temperature before transferring it to an airtight container. For longer storage, consider freezing the soup in portions; just make sure to leave some space in the container as soup expands when frozen. When reheating, gently warm on the stove or in the microwave until heated through, stirring occasionally for even temperature.
