Ingredients Overview for Keto Broccoli and Cauliflower Au Gratin with Sausage
Here’s what you’ll need to whip up this dish. Don’t be intimidated; it’s all pretty straightforward, and you can easily swap out ingredients if necessary!
- Broccoli: Fresh or frozen works! Just make sure to chop it into bite-sized pieces.
- Cauliflower: You can use fresh florets or frozen cauliflower. Both will work beautifully.
- Sausage: I like to use spicy Italian sausage, but feel free to use chicken or turkey sausage for a leaner option.
- Cream Cheese: This adds a lovely creamy texture. If you want a dairy-free option, you could use coconut cream.
- Cheddar Cheese: Sharp cheddar really elevates the flavor. You can substitute with mozzarella or a blend if you prefer something milder.
- Heavy Cream: This gives it that indulgent richness. You can use half and half, but it won’t be as creamy.
- Garlic Powder and Onion Powder: These are essential for flavor! I also love to sneak in a bit of paprika for some extra depth.
- Salt and Pepper: This will vary based on your taste, but don’t skimp on seasoning; it makes a big difference!
Step-by-Step Instructions for Keto Broccoli and Cauliflower Au Gratin with Sausage
Let’s get down to the nitty-gritty and bring this dish to life!
- Prep the Vegetables: Preheat your oven to 375°F (190°C). While it’s warming up, wash and chop the broccoli and cauliflower into manageable pieces.
- Cook the Sausage: In a large skillet over medium heat, cook your sausage until browned and cooked through. Break it into pieces as you cook. Remove it from the pan and set it aside.
- Make the Cheese Sauce: In the same skillet, lower the heat and add in your cream cheese and heavy cream. Stir until it’s smooth and creamy. Add the garlic powder, onion powder, and half of the cheddar cheese, stirring until melted and combined.
- Combine Everything: In a large mixing bowl, combine the broccoli, cauliflower, sausage, and cheese sauce. Make sure every piece of vegetable is coated in that gooey goodness.
- Bake: Pour everything into a greased casserole dish. Top with the remaining cheddar cheese and bake for about 25-30 minutes, or until it’s bubbly and golden brown on top.
- Serve: Let it cool for a few minutes, then dig in!

Serving Suggestions
This cheesy goodness pairs wonderfully with a simple green salad or some roasted Brussels sprouts on the side. For an added treat, serve it with some low-carb garlic bread or a slice of keto-friendly crusty bread to mop up the creaminess. You could also spice things up with a dollop of hot sauce on top if you’re feeling adventurous!
Tips For The Perfect Keto Broccoli and Cauliflower Au Gratin with Sausage
- Blanch the Vegetables: If you’re using fresh broccoli and cauliflower, you can blanch them in boiling water for 2-3 minutes before incorporating. This makes them tender but still crispy.
- Add Extra Protein: Consider adding some cooked bacon or chicken for an even heartier dish.
- Cheese Lovers: Mix up your cheeses! A touch of goat cheese or mozzarella can really change things up.
- Storage Tips: This dish can be refrigerated for up to 3 days. Just reheat in the oven for a warm meal anytime.
Q&A Section
Can I use frozen vegetables?
Absolutely! Frozen broccoli and cauliflower will work perfectly. Just make sure to thaw and drain excess water.
What if I don’t like sausage?
You can omit the sausage or replace it with cooked ground beef or even mushrooms for a vegetarian version.
How do I make this dairy-free?
For a dairy-free option, use coconut cream instead of heavy cream and dairy-free cheese alternatives.
Can I prepare this ahead of time?
Yes! You can assemble the casserole earlier in the day and bake it when you’re ready to serve.
