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

Step 1: Preheat the Oven
Begin by preheating your oven to 350°F (175°C). This ensures that your Keto Broccoli and Cauliflower Au Gratin with Sausage bakes evenly, achieving that perfect bubbling, golden finish. While the oven heats, gather all your ingredients and equipment, setting yourself up for a smooth cooking experience.

Step 2: Sauté the Sausage
In a large skillet over medium-high heat, add your sliced smoked sausage. Sauté for about 5-7 minutes, stirring occasionally, until the sausage is nicely browned and slightly crisped. This step enhances the flavor of the sausage, infusing your dish with a savory base. Once done, transfer the sausage to a plate and set it aside.

Step 3: Cook the Aromatics
In the same skillet, melt 2 tablespoons of butter over medium heat. Add in the finely diced onion and cook for 3-4 minutes until it’s translucent and soft. The aroma will be delightful! Stir in the minced garlic and sauté for an additional 30 seconds, ensuring the garlic becomes fragrant but does not burn.

Step 4: Make the Cheese Sauce
Now, add the softened cream cheese to the skillet, stirring until fully melted and combined with the onion and garlic. Gradually pour in 1 cup of heavy whipping cream, whisking continuously to create a smooth sauce. Keep the heat on medium-low, allowing it to simmer for about 3-5 minutes until the mixture thickens slightly, making it rich and creamy.

Step 5: Add Cheddar Cheese
Once your sauce has thickened, stir in 1 to 2 cups of shredded cheddar cheese, mixing until melted and creamy. Season with salt and pepper to taste, allowing those flavors to meld beautifully. This cheesy goodness will envelop your veggies later, making your Keto Broccoli and Cauliflower Au Gratin with Sausage extra creamy and delicious.

Step 6: Combine Ingredients
In a large mixing bowl, combine the sautéed sausage, cooked cauliflower, and fresh broccoli florets. Pour the luscious cheese sauce over this mixture and stir gently until everything is well coated. The vibrant colors and enticing aroma will remind you why this dish is a family favorite.

Step 7: Bake the Casserole
Transfer the prepared mixture into a greased 9×9 baking dish, spreading it out evenly. Place it in your preheated oven and bake for 15-20 minutes. Keep an eye on it; you’ll know it’s done when the top is bubbling and golden, and the kitchen is filled with a mouthwatering aroma that promises a sumptuous meal ahead.
