1-First, preheat the oven to 350 degrees Fahrenheit. In a skillet over medium-high heat, sauté the sliced smoked sausage until it’s nicely seared, then set it aside.

2-Next, in a pot over medium heat, melt the butter and add the diced onion, cooking until it’s softened, followed by the minced garlic for about 30 seconds.

3-Then, stir in the softened cream cheese until it’s fully melted, and pour in the heavy whipping cream, whisking to combine. Let this simmer over medium-low heat until it thickens, then add the shredded cheddar cheese and season with salt and pepper to taste. In a separate bowl, mix the lightly steamed cauliflower, broccoli, and sausage together, pour the cheese sauce over it, and stir well to coat everything evenly.

4-Finally, spread the mixture into a 9×9 baking dish and bake for 15-20 minutes, or until it’s bubbly and golden on top.
