What is Keto Broccoli Cauliflower Casserole
Casseroles have been a staple of home cooking for generations, blending wholesome ingredients into one comforting dish.
This keto-friendly version draws inspiration from classic vegetable bakes but keeps things low in carbs and entirely plant-based. Instead of traditional starch-heavy additions, I use hearty broccoli and cauliflower, combined with savory vegan ground beef and crushed tomatoes.
The result? A deliciously rich and creamy dish that satisfies without compromising a ketogenic lifestyle.
Ingredients for the Best Results
The key to an exceptional casserole is in the quality and combination of ingredients. Fresh broccoli and cauliflower florets create the perfect base, providing a satisfying bite while absorbing the flavors of the sauce.
Sautéed onions and garlic bring a deep, aromatic foundation, while crushed tomatoes add a hint of tangy sweetness. The vegan ground beef contributes a robust, meaty texture, making every bite fulfilling.
And of course, a generous amount of dairy-free cheese binds it all together, with some reserved for that golden, melty topping that makes casseroles so irresistible. A drizzle of olive oil enhances the richness while keeping everything perfectly moist.
How to Make Keto Broccoli Cauliflower Casserole
I start by preheating the oven, setting the stage for all the flavors to meld beautifully.
The broccoli and cauliflower florets are fist boiled in salt water — just enough to soften them a bit, about 4-5 minutes max.
Meanwhile, onions and garlic sauté in a pan, filling the kitchen with their mouthwatering aroma. The vegan ground beef and crushed tomatoes join in, simmering into a luscious, savory mixture.
In a baking dish, the casserole is layered: first the broccoli and cauliflower, followed by the tomato-sauce-beef mixture, and finally vegan cheese. Repear ones. Finally, the Keto Broccoli Cauliflower Casserole is baked to golden perfection.
Tips and Tricks for Leftovers
This casserole is just as good the next day—maybe even better! Storing it in an airtight container keeps the flavors locked in, making for an easy reheat-and-eat meal.
Warming Keto Broccoli Cauliflower Casserole up in the oven helps maintain that crisp cheesy top, but if you’re in a hurry, a quick zap in the microwave works too.
If you love meal prep, this dish freezes beautifully. Just portion it out, freeze, and enjoy a comforting, homemade meal anytime.
Ideas for Variations
There are endless ways to tweak this recipe while staying true to its keto-friendly nature. Adding mushrooms brings an earthy depth, while a handful of spinach sneaks in extra greens.
If you like a spicy kick, a sprinkle of chili flakes or diced jalapeños does the trick. For an even creamier texture, a splash of coconut cream can elevate the dish to another level of indulgence.
The beauty of this casserole is its versatility—you can truly make it your own.
