Try this Slow Cooker Broccoli Cheese Soup recipe
Can this dairy-heavy soup actually survive a trip through the freezer? The short answer is yes, provided you alter your cooking expectations for emulsion stability. Broccoli cheddar preparations trace their roots back to mid-century American comfort food trends, heavily reliant on commercial processed cheese blocks before shifting toward scratch-made roux bases. When freezing milk-and-cream-based soups, proteins tend to coagulate and separate upon thawing, leaving a grainy texture behind. To combat this physical breakdown, undercook the broccoli florets slightly by shaving ten minutes off the slow cooker duration, then store the base without the final cheddar addition. Reheat the thawed base slowly over medium-low heat in a heavy-bottomed saucepan, whisking constantly to re-emulsify the fats before stirring in the fresh sharp cheddar at 165 degrees Fahrenheit. Higher fat dairy such as heavy cream handles freezing significantly better than fat-free alternatives because milk solids provide a protective buffer against separation. Dice the yellow onions uniformly to one-quarter inch so they soften completely without turning mushy during the four-hour high heat cycle. Whisk the milk into the roux very gradually, pouring in a steady stream while beating vigorously to prevent lumps from forming in the starch matrix. Keep a microplane grater ready for adjusting seasonings at the table.
