How to Make Keto Broccoli and Cauliflower Au Gratin with Sausage

Step 1: Preheat the Oven

First things first, let’s get that oven ready! Preheat it to 350 degrees Fahrenheit. This step is crucial to ensure your Keto Broccoli and Cauliflower Au Gratin with Sausage bakes evenly. While it heats up, you can move on to the next steps. It’s a little moment that always makes me feel organized and ready to tackle the recipe at hand.

Step 2: Sauté the Sausage

Now, grab a skillet and set it over medium-high heat. Add your sliced smoked sausage and let it sizzle until slightly browned and deliciously seared. As the aroma fills your kitchen, you’ll know it’s time to remove the sausage and set it aside. Trust me, this step lays the groundwork for vibe and flavor in the dish!

Step 3: Prepare the Cheese Sauce

In the same skillet, reduce the heat and add in the butter. Let it melt, and then toss in the diced onions. Sauté them until they soften, releasing their sweet scent, about 3-4 minutes. Next, mix in the minced garlic and sauté for just 30 seconds until fragrant—don’t overdo it, or those delicate flavors might get burnt!

Once your onions and garlic are at the perfect stage, add the softened cream cheese. Stir until it melds smoothly with the onions and garlic. Pour in the heavy whipping cream, whisking until everything is well combined. Reduce the heat to low and let it simmer gently. The creamy sauce will thicken beautifully as it warms.

Finally, stir in the shredded cheddar cheese, allowing it to melt completely into that velvety sauce. Taste and season with salt and pepper to your heart’s content. You’ll want it to be just right!

Step 4: Combine Vegetables and Sauce

In a large mixing bowl, combine the lightly steamed cauliflower and broccoli florets with the seared sausage. Pour that luscious cheese sauce over the top, and give it a good stir until everything is coated in cheesy goodness. This point in the recipe really amplifies your kitchen experience, as it all starts to come together!

Step 5: Bake to Perfection

Transfer the mixture to a 9×9 baking dish, spreading it out evenly. Pop it into your preheated oven and bake for 15 to 20 minutes until bubbling and golden on top. This will create a beautiful bubbly dish that not only tastes incredible but also looks inviting. Serve it warm, and watch everyone come back for seconds!

Tips for Success

Don’t overcook the broccoli and cauliflower; they should remain tender yet crisp.
Feel free to make the cheese sauce in advance and store it in the fridge.
Adjust seasoning as needed; taste as you go for the best flavor.
For an extra cheesy touch, sprinkle additional cheese on top before baking.
Have fun with variations: try different vegetables or sausage for unique flavor.

Equipment Needed

Skillet: A non-stick or cast-iron skillet works great for sautéing.
9×9 Baking Dish: If you don’t have this size, a similar oven-safe dish will do.
Mixing Bowl: Any large bowl for combining the ingredients will suffice.
Whisk: Essential for mixing your creamy cheese sauce smoothly.

Variations

Getting creative with this Keto Broccoli and Cauliflower Au Gratin with Sausage can add a delightful twist to the dish. Here are some fun ideas to consider:

Vegetarian Option: Skip the sausage and replace it with sautéed mushrooms or tempeh for a hearty alternative.
Different Cheeses: Try mozzarella, gouda, or pepper jack cheese for a unique flavor profile.
Herbs and Spices: Add fresh thyme or smoked paprika for an extra punch of flavor.
Cream Alternatives: Use coconut cream for a dairy-free version while maintaining that creamy consistency.

Drink Pairing: Enjoy with a refreshing sparkling water or a dry white wine.
