- Brown the sausage slices in a large skillet over medium-high heat until golden and crisp, about 5–7 minutes.
- Remove the sausage and set aside.
- Sauté the onion in melted butter over medium heat until softened, about 3–4 minutes, then add the garlic.
- Make the cheese sauce by adding cream cheese, stirring until melted, then gradually whisk in heavy cream and let it simmer until thickened.
- Combine broccoli and cauliflower florets with browned sausage in a bowl, pour the cheese sauce over, and toss until coated.
- Transfer the mixture to a baking dish and spread evenly, then bake for 15–20 minutes until bubbling and golden.
