Serve with a sprinkling more of cheese because let’s be honest, there can never be enough cheese. Maybe sprinkle a few croutons if you have some lying around.

You might want to make a double batch of this because leftovers the next day are even better.

  2. 1/4 cup all-purpose flour

  1. Heat a medium sauce pot over medium heat. Add the butter and allow to melt. Stir in the flour, whisking thoroughly and cooking for a few seconds to develop the flavor.

    I’m currently making this recipe in the crockpot already, and it smells delicious! I have one suggestion: Add to the recipe to stir the contents of the soup every once in a while to make sure all ingredients stay corporated. You mention it above but not in the final recipe at the bottom. It might be helpful for future cooks!

    Thanks for all your delicious recipes!

    Awesome! I love making soups and Broccoli Cheddar is one of my favorites. Followed recipe exactly as you should always do first time making and family loved it. I will lessen amount of broth next time for a thicker broth. Keeper! Thank you Rachel.

    I made this soup today, per the recipe except I used frozen broccoli florets, and it turned out ahhhmazzing. SO yummy. I cooked it on high for just 2.5 hours and everything was tender. Served it with some hot rolls. Highly recommend this recipe. It was easy to prepare and oh-so-comforting if comfort food is what you are in the mood for. Thanks for this recipe!

    Not sure if you’ll know this, but if I cook it on high for the suggested time and then let it hang out in the warm setting until we’re ready to eat, do you think the cheese will curdle or will it be ok for a little?
