- ¾ cup shredded cheddar cheese
- ¾ cup shredded Gruyère cheese (or Swiss cheese)

How to Make The Best Keto Broccoli Cauliflower Au Gratin:
This recipe is a symphony of simplicity and flavor, offering a deliciously creamy, cheesy indulgence without the carb guilt. Its straightforward steps ensure a satisfying meal ready in about 45 minutes. The tender-crisp vegetables, enveloped in a rich, velvety cheese sauce, create a truly comforting experience.
Step-by-Step Instructions:
- Prepare the Vegetables: In a large pot, bring salted water to a boil. Add the broccoli and cauliflower florets and blanch for 3-4 minutes until they are tender-crisp. Drain the vegetables thoroughly and set them aside. Overcooking them at this stage will result in a mushy final dish.
- Sauté Aromatics: While the vegetables are blanching, melt the butter in a large oven-safe skillet or Dutch oven over medium heat. Add the finely chopped onion and cook until it becomes softened and translucent, about 5-7 minutes. Add the minced garlic and cook for another minute until fragrant, being careful not to burn it.
- Create the Cheese Sauce: Pour the heavy cream into the skillet with the sautéed onions and garlic. Bring the cream to a gentle simmer, stirring occasionally. Reduce the heat to low and let it warm through for about 2-3 minutes.
- Melt the Cheese: Gradually add the shredded cheddar cheese, Gruyère cheese, and grated Parmesan cheese to the cream, stirring constantly until the cheeses are fully melted and the sauce is smooth and creamy. Season the sauce with salt, black pepper, and the pinch of nutmeg (if using). Taste and adjust seasonings as needed.
- Combine and Bake: Add the blanched broccoli and cauliflower florets to the cheese sauce in the skillet. Gently toss them to ensure each piece is well-coated. If you’re not using an oven-safe skillet, transfer the mixture to a greased 8×8 inch baking dish.
- Top and Bake: For an extra cheesy crust, sprinkle a bit more shredded cheese over the top of the casserole. Place the skillet or baking dish in a preheated oven at 375°F (190°C). Bake for 20-25 minutes, or until the sauce is bubbly and the top is golden brown and irresistible.
- Rest and Serve: Once baked, remove the dish from the oven and let it rest for 5-10 minutes before serving. This allows the sauce to set slightly, making it easier to serve and enhancing the flavors. Garnish with fresh parsley if desired.

Storing and Reheating Tips:
To keep your Best Keto Broccoli Cauliflower Au Gratin fresh for future enjoyment, allow it to cool completely at room temperature after baking. Once cooled, transfer it to an airtight container and refrigerate. It will stay fresh and delicious in the refrigerator for up to 3-4 days.
When you’re ready to reheat, you have a few excellent options for optimal taste:
- Oven Reheating: This is the best method to bring back that wonderful creamy texture and achieve a nice bubbly top. Preheat your oven to 350°F (175°C). Transfer the desired portion to an oven-safe dish, cover loosely with foil, and bake for 15-20 minutes, or until heated through. Remove the foil for the last 5 minutes to allow the cheese to re-melt and brown slightly.
- Microwave Reheating: For a quicker option, place a serving in a microwave-safe dish. Cover and microwave on medium power in 30-second intervals, stirring in between, until heated through. Be aware that microwaving can sometimes alter the creamy texture slightly.
If you plan to freeze portions for even longer storage, let the gratin cool completely, then portion it into freezer-safe containers or wrap individual servings tightly in plastic wrap followed by aluminum foil. Frozen gratin can be kept for up to 2-3 months. To reheat from frozen, bake in a preheated oven (350°F/175°C) for a longer duration, starting with about 30-40 minutes, and removing the foil towards the end.
