When to Serve Low Carb Cauliflower Sausage Casserole
This casserole works well for almost any occasion.
It’s perfect for busy weeknights when you want something warm and nourishing without spending hours in the kitchen. It also makes a fantastic option for brunch spreads, potlucks, or family dinners where you want to offer a dish that feels indulgent but is still on the lighter side.
It even reheats wonderfully, making it a great make-ahead meal for meal prepping.
Choosing the Best Ingredients
To get the best results, focus on quality ingredients.
Fresh cauliflower florets bring a natural sweetness once roasted, while garlic and olive oil lay the foundation of flavor. A good plant-based sausage adds depth and spice, while frozen spinach contributes an earthy balance.
Non-dairy sour cream and cheese create the creamy, melty topping that makes this casserole truly comforting. Each ingredient works together to keep the recipe low in carbs but high in flavor.
What Makes This Low Carb Cauliflower Sausage Casserole Special
Unlike many casseroles that rely heavily on pasta or rice, this version centers cauliflower as the base, giving you all the satisfaction of a traditional bake without the extra carbs.
The creaminess from the sour cream and cheese pairs beautifully with the sausage and spinach, while the garlic and olive oil tie everything together.
It’s the perfect example of how comfort food can be wholesome and simple at the same time.
How to Make Low Carb Cauliflower Sausage Casserole
Start by cooking the cauliflower florets in lightly salted water until tender. Drain them in a colander and transfer to a baking dish.
In a skillet, cook the plant-based sausage until nicely browned, then stir in the frozen spinach until heated through. Season with garlic, salt and pepper.
Stir in the sour cream and about half of the vegan cheese. Let it melt on low temperature.
Now give everything over the cauliflower in the baking dish and top with the remaining half of the cheese. Bake until the casserole is bubbling, creamy, and golden brown on top.
What to Do with Leftovers
This low carb cauliflower sausage casserole keeps beautifully in the fridge for a few days and tastes even better the next day as the flavors deepen.
You can reheat it in the oven or simply warm it up in the microwave for a quick lunch or dinner.
Leftovers can also be portioned into containers, making it ideal for meal prep throughout the week.
Ideas for Variations
This recipe is wonderfully flexible.
You can swap the spinach for kale or broccoli, use different sausage flavors to change up the seasoning, or add extra vegetables like mushrooms or bell peppers. For a little crunch, top the casserole with a sprinkle of crushed nuts or seeds before baking.
Each variation keeps the spirit of the recipe while letting you customize it to your taste.
Frequently Asked Questions
Yes, you can assemble the casserole ahead of time, cover, and refrigerate until ready to bake. Just add a few extra minutes in the oven if it’s chilled.
Absolutely. Allow the casserole to cool completely, then wrap it tightly and freeze. To reheat, thaw overnight in the fridge and bake until warmed through.
Since frozen spinach is already blanched, it just needs to be thawed and squeezed of excess water before adding it to the casserole.
Yes, fresh cauliflower works best for texture, but frozen florets will also work in a pinch—just be sure to roast them long enough so they don’t release too much water into the casserole.
Why This Recipe Stands Out
There are many cauliflower casserole recipes out there, but what sets this one apart is its balance of creaminess, bold flavor, and simplicity.

Ingredients
- 5 cups cauliflower florets
- 3 cloves garlic
- 1 tablespoon olive oil
- 8 ounces plant-based sausage
- 16 ounces spinach, thawed
- 6 ounces dairy-free sour cream
- 7 ounces non-dairy cheese, shredded, divided
- Salt, pepper to taste
Instructions
- Bring a large pot of lightly salted water to a boil. Add the cauliflower florets and cook for 8–10 minutes, until fork-tender. Drain well in a colander and transfer to a lightly greased baking dish.
- Heat a skillet over medium heat. Add the plant-based sausage and cook for 5–6 minutes, breaking it up and stirring occasionally, until browned. Stir in the frozen spinach and cook for another 3–4 minutes, until heated through. Season with minced garlic, salt, and pepper to taste.
- Reduce the heat to low. Stir in the sour cream and about half of the non-dairy cheese. Let the mixture cook for 2–3 minutes, stirring gently, until the cheese begins to melt and the sauce is creamy.
- Pour the sausage and spinach mixture over the cauliflower in the baking dish. Spread evenly, then sprinkle the remaining half of the cheese on top.
- Preheat the oven to 375°F (190°C). Bake uncovered for 20–25 minutes, until the casserole is bubbling, creamy, and golden brown on top.
- Let the casserole rest for 5 minutes before serving to allow the flavors to settle.
