For a richer flavor, try roasting the squash instead of steaming it. Toss the cubed squash with olive oil, salt, and pepper, then roast at 400°F (200°C) until tender and slightly caramelized. Experiment with different cheeses! Gruyere, Monterey Jack, or even a smoked Gouda would be delicious alternatives to Cheddar. If you prefer a thinner soup, add more milk or broth until you reach your desired consistency. This soup is delicious served hot or cold, making it a versatile dish for any time of year. To make this recipe vegan, substitute the whole milk with cashew or almond milk and use a plant-based cheddar alternative.
