Step‑by‑Step Instructions for Keto Broccoli and Cauliflower Au Gratin With Sausage

Step 1: Preheat the Oven
Start by preheating your oven to 350°F (175°C). This ensures it’s hot and ready for your bubbling Keto Broccoli and Cauliflower Au Gratin with Sausage once everything is assembled. While the oven heats, you can gather your ingredients, making the process smooth and efficient.

Step 2: Sear the Sausage
In a large skillet over medium heat, add the sliced smoked sausage. Sear it for about 5-7 minutes, stirring occasionally, until the sausage is browned and slightly crispy. This step enhances the flavor profile of your dish, infusing the au gratin with delicious savory notes.

Step 3: Sauté the Onions
Next, melt 2 tablespoons of butter in a medium pot over medium heat. Add the diced onion, sautéing for 3-4 minutes until it turns soft and translucent. The buttery aroma fills the kitchen, creating a wonderful base for your cheese sauce as you prepare for the next step.

Step 4: Add Garlic
Once the onions are ready, stir in the minced garlic and cook for an additional 30 seconds. This brief sauté allows the garlic to release its fragrant aroma without burning, adding an irresistible depth of flavor to your Keto Broccoli and Cauliflower Au Gratin with Sausage.

Step 5: Create the Cheese Sauce
Lower the heat slightly, then add the softened cream cheese to the pot, mixing until it melts into the onion and garlic blend. Gradually pour in the heavy whipping cream, whisking for about 3-5 minutes until the sauce thickens to a creamy consistency that clings to the back of a spoon.

Step 6: Incorporate Cheddar
Once your sauce is thickened, stir in the shredded cheddar cheese until it melts completely into the mixture. If desired, season with salt and pepper for that extra kick. The sauce should be smooth and cheesy, ready to envelop your vegetables and sausage.

Step 7: Combine the Ingredients
In a large mixing bowl, combine the lightly steamed cauliflower florets, broccoli florets, and the sautéed sausage. Pour the rich cheese sauce over the vegetables and sausage, mixing everything until well coated. This ensures every bite of your Keto Broccoli and Cauliflower Au Gratin with Sausage is packed with flavor.

Step 8: Bake the Au Gratin
Transfer the mixture into a greased baking dish, spreading it evenly. Place it in the preheated oven and bake for 15-20 minutes, or until the top is bubbling and golden brown. Keep an eye on it, as the enticing aroma will let you know it’s almost ready to serve!
