  • 1 cup heavy whipping cream
  • 2 cups sharp cheddar cheese freshly shredded

Instructions
 

Cooking Instructions

  • Preheat oven to 350 °F (175 °C) and lightly grease a 9×9-inch baking dish.
  • Steam the cauliflower and broccoli florets until just tender, about 5–6 minutes; drain and pat dry so the sauce isn’t watery.
  • In a large skillet over medium-high heat, cook the sliced sausage until lightly browned; transfer to a paper towel to drain excess fat.
  • Using the same skillet, melt the butter over medium heat. Add the diced onion and sauté until soft and translucent.
  • Add minced garlic and cook for 30 seconds until fragrant.
  • Stir in cream cheese until mostly melted, then pour in heavy cream and whisk until smooth; let simmer 2–3 minutes until slightly thickened.
  • Reduce heat, gradually add the cheddar cheese, and stir until fully melted and creamy. Season with salt, pepper, and paprika (if using).
  • In a large bowl, combine steamed veggies and browned sausage; pour the cheese sauce over and gently fold to coat everything evenly.
  • Transfer the mixture to the prepared baking dish and spread evenly. If desired, sprinkle extra shredded cheddar on top.
  • Bake uncovered for 15–20 minutes until bubbly and lightly golden. Let rest 5 minutes before serving, then garnish with fresh chives or green onions.

Notes

Serve hot for best flavor and texture.
