Bring a large pot of lightly salted water to a boil. Add pasta and cook for 8 to 10 minutes or until al dente. Drain, and return to pot.
Heat oil in a large heavy skillet over medium heat. Saute onion until soft and translucent. Stir in ham, and heat through. Mix onion, ham and broccoli with pasta in pot. Mix in creme fraiche until evenly coated.
