Reserve 1 cup of the cooking liquid from the pot and discard the rest.
Add half of the broccoli, reserved cooking liquid, unsweetened almond milk, heavy cream, and salt and pepper to a blender. Blend well until smooth.
Add the blended ingredients into the remaining broccoli in the pot and stir together with Parmesan cheese and lemon juice. Continue cooking until heated through.
Taste and season with additional salt and pepper if needed. Serve with a sprinkle of Parmesan cheese over the top.
