Bring a large pot of lightly salted water to a boil. Add broccoli and cook, uncovered until bright green, about 2 to 3 minutes. Remove from water promptly and spread out on a platter or surface to dry.
Preheat oven to 350℉ (175℃). Combine (in this order) cottage cheese, eggs, olive oil, Boursin cheese, potato starch, salt and pepper to taste, in a mini food processor and blend until completely smooth (1 minute). Transfer broccoli to a 9x13 baking dish. Next EVENLY pour the cottage cheese mixture over broccoli and then add the cheddar cheese on top. Bake for 45-50 minutes.
