For the smoothest texture, grate your own cheddar cheese instead of using pre-shredded, which often contains anti-caking agents that can cause graininess. Keep the heat low after adding cream and cheese to prevent the soup from separating. To meal prep, cool the soup completely and store it in airtight containers in the refrigerator for up to 4 days, or freeze in portions and thaw overnight in the fridge before reheating gently on the stove. Thin with a splash of broth or cream if it thickens as it stands. This soup is very rich, so a small bowl paired with a crisp green salad makes a satisfying keto meal.
