Photos of Low-Carb Cauliflower Baked Ziti



While we love the rich flavor that roasting cauliflower in the oven brings, there are plenty of other ways to cook cauliflower.

  • Steaming: Steam cauliflower florets in a steamer basket over boiling water for 5-7 minutes until tender but still slightly crisp.
  • Sautéing: Heat a tablespoon of olive oil or butter in a skillet over medium heat. Add cauliflower florets and cook, stirring occasionally, for 5-7 minutes until lightly browned and tender.
  • Boiling: Bring a pot of salted water to a boil and add cauliflower florets. Cook for 5-7 minutes until fork-tender, then drain well. *Be careful not to overcook.
  • Microwaving: Place cauliflower florets in a microwave-safe dish with a couple of tablespoons of water. Cover with a microwave-safe lid or microwave-safe plastic wrap and cook on high for 3-5 minutes until tender.
  • Grilling: Cut cauliflower into thick slices or wedges, brush with olive oil, and season with salt, pepper, and your favorite herbs or spices. Grill over medium-high heat for 8-10 minutes per side until charred and tender.

Italian sausage

Make sure to check the ingredients of your Italian sausage for sugar, as some brands include quite a bit of sugar in their ground sausage.

Marinara sauce

Our favorite brand of marinara sauce to use is Rao’s Marinara Sauce. The sauce tastes delicious and is lower in carbs than many other brands. Make sure whichever brand you select doesn’t have any added sugar.

Additional Details

Our low-carb cauliflower baked ziti is a comforting dish that offers a nutritious twist on the classic Italian favorite, providing a flavorful alternative that’s not only delicious but also fits into a low-carb lifestyle.

The origins of baked ziti trace back to Italy, where it has long been cherished as a hearty comfort food. Traditionally made with pasta, cheese, and marinara sauce, this dish has undergone various adaptations over the years. In recent times, with the growing emphasis on healthier eating habits, people have been looking for alternative ingredients to lighten up classic recipes. Thus, the idea of substituting cauliflower for pasta in baked ziti was born, offering a lower-carb option without sacrificing taste or satisfaction.

Details about ingredients

  • Cauliflower: Low in carbs and rich in essential vitamins like C, K, and folate, cauliflower offers a nutritious base. Its high fiber content aids digestion and helps regulate blood sugar levels, making it ideal for diabetes management. Cauliflower also boasts antioxidants that may reduce inflammation and lower chronic disease risk.
  • Italian sausage: Look for options without added sugars or fillers to keep carbs in check.
  • Marinara sauce: Made from tomatoes, herbs, and spices, marinara provides a flavorful tomato base. Tomatoes are rich in lycopene, an antioxidant with anti-inflammatory properties. They also pack vitamins A and C, plus potassium for heart health.
  • Ricotta, Parmesan, and mozzarella cheeses: These cheeses add creamy texture and essential nutrients. Ricotta is high in protein and calcium for bone health. Parmesan offers calcium and phosphorus while enhancing flavor. Mozzarella is lower in sodium and provides calcium and protein for a nutritious boost.


  • Veggie lovers: For a meatless option bursting with flavor, skip the Italian sausage and load up on colorful veggies instead. Try sautéed mushrooms, bell peppers, onions, and spinach for a deliciously wholesome twist.
  • Chicken Florentine: Swap out the Italian sausage for grilled or roasted chicken breast strips. Layer the chicken on top of the cauliflower, marinara, and cheeses, then add a generous handful of fresh spinach leaves for a protein-packed, veggie-filled delight.
  • Seafood: Instead of Italian sausage, try mixing in cooked shrimp, crabmeat, or chunks of flaky white fish for a taste of the ocean. Pair with a squeeze of lemon juice and a sprinkle of fresh parsley for a burst of freshness.
  • Mediterranean: Replace the Italian sausage with ground lamb or turkey seasoned with Mediterranean spices like oregano, cumin, and paprika. Add diced tomatoes, olives, and feta cheese for a flavorful Mediterranean twist.
  • Vegan: For a plant-based option, omit the meat and dairy entirely. Substitute vegan sausage or crumbled tofu seasoned with Italian herbs for protein. Use dairy-free ricotta, Parmesan, and mozzarella alternatives, or make your own cashew-based cheese sauce for a creamy, dairy-free indulgence.

Serving pairings

  • Green salad: Serve alongside a salad dressed with your favorite dressing for a refreshing contrast.
  • Roasted vegetables: Pair with roasted broccoli, zucchini, or asparagus for added fiber and vitamins.
