Preheat the oven to 300 degrees F. Whisk the eggs, cream, 1 teaspoon salt and a few grinds of black pepper together in a large bowl until smooth. Fold in the broccoli, ham, Cheddar and Monterey Jack until well combined.
Pour the mixture into an oven-safe, 10-inch nonstick skillet. Bake until the eggs are just set and no longer jiggly in the middle, 50 to 55 minutes. Let sit for 5 minutes before sliding the frittata out of the skillet onto a serving platter. Slice into wedges to serve.
