Step‑by‑Step Instructions for Low Carb Pizza Casserole
Step 1: Preheat the Oven
Begin by preheating your oven to 400°F (200°C). This ensures a perfectly baked Low Carb Pizza Casserole with a bubbly, golden top. While the oven warms, you can gather your ingredients and equipment, including a microwave-safe bowl, skillet, and a 13×9 inch casserole dish for assembly.
Step 2: Prepare the Cauliflower
Place the cauliflower florets in a microwave-safe bowl, adding a splash of water to help steam. Microwave for about 3 minutes until tender. Once done, carefully drain the water, then pat the florets dry with a paper towel to prevent excess moisture, which can affect the casserole’s texture.
Step 3: Cook the Sausage
In a skillet over medium heat, brown the Italian sausage for approximately 15 minutes, stirring occasionally. Once it’s nicely cooked, drain any excess grease to keep your casserole lighter. This savory base will add a robust flavor to your Low Carb Pizza Casserole.
Step 4: Sauté the Vegetables
Using the same skillet, add sliced mushrooms and sauté for about 10 minutes until they become tender and moisture evaporates. This step intensifies their flavor, contributing to the overall taste of your Low Carb Pizza Casserole. Set them aside once done.
Step 5: Assemble the Casserole
Grease your 13×9 inch casserole dish with cooking spray, then spread ½ cup of pasta sauce evenly on the bottom. This layer of sauce prevents sticking and adds flavor. It’s the first step in creating the delicious layers of your casserole.
Step 6: Mix the Filling
In a large mixing bowl, combine the steamed cauliflower, cooked sausage, sautéed mushrooms, and chopped green peppers. Mix everything together until evenly distributed. This colorful filling is packed with flavor and forms the hearty base of your Low Carb Pizza Casserole.
Step 7: First Layer of the Casserole
Layer half of the cauliflower mixture into the prepared casserole dish. Pour ½ cup of pasta sauce over the filling, followed by half of the pepperonis and 6 oz of mozzarella cheese. This ensures a delightful flavor and gooey texture in every bite.
Step 8: Repeat for the Second Layer
Repeat the layering process by adding the remaining mixture, topping it with another ½ cup of sauce, the rest of the pepperonis, and another generous layer of mozzarella cheese. Each layer builds flavor, making your Low Carb Pizza Casserole irresistible.
Step 9: Add Finishing Touches
In a small bowl, blend the Parmesan cheese with Italian seasoning and sprinkle it over the top of your casserole. Add any reserved pepperoni slices to intensify the pizza flavor. This final touch enhances both the taste and presentation of your dish.
Step 10: Bake to Perfection
Place the casserole in the preheated oven and bake for about 30 minutes. You’ll know it’s ready when the cheese is melted, bubbly, and lightly golden. This step transforms all the delicious elements into a cohesive and comforting Low Carb Pizza Casserole.
Step 11: Cool and Serve
Once out of the oven, allow the casserole to cool for 10-15 minutes before slicing. This resting time helps the layers set, making it easier to serve. Enjoy the delightful flavors of your homemade Low Carb Pizza Casserole with family and friends!

Easy Low Carb Pizza Casserole Recipe FAQs
How do I select ripe cauliflower for the casserole?
Absolutely! When choosing cauliflower, look for heads that are firm, with tightly packed florets and no dark spots or blemishes. A fresh cauliflower should feel heavy and have bright white or creamy color. If you see any yellowing or browning of the florets, it’s best to choose another one.
What’s the best way to store leftover Low Carb Pizza Casserole?
Very good question! You can refrigerate leftovers in an airtight container for up to 4 days. Just make sure it’s well-sealed to help maintain its flavor and moisture. When you’re ready to enjoy it again, simply reheat in the microwave or oven until warmed through.
Can I freeze the Low Carb Pizza Casserole?
Absolutely! You can freeze the unbaked casserole in a freezer-safe dish for up to 3 months. If you prefer freezing cooked portions, they can be stored for up to 2 months. To reheat, simply thaw overnight in the refrigerator, then warm in the oven for a delightful meal.
What should I do if my casserole seems watery after baking?
If you notice your casserole is watery, it usually occurs due to excess moisture in the vegetables or sauce. To avoid this, ensure you thoroughly pat dry the cauliflower after steaming, and drain cooked sausage well. Also, opting for a thick pasta sauce can prevent excess liquid during baking. If it’s already baked and watery, consider using a slotted spoon when serving to help drain off some of the liquid.
Are there any dietary considerations I should know about?
Yes! If you’re making this casserole for someone with allergies, be mindful of the ingredients. The recipe includes cheese and sausage, so consider alternatives like dairy-free cheese and turkey or chicken sausage for those watching their fat intake. This dish is keto-friendly and generally suitable for low-carb diets, but always check labels to ensure all toppings meet your dietary needs.
How do I make my casserole spicier?
If you’re looking for a bit of a kick, add sliced jalapeños or crushed red pepper flakes to your filling for an exciting heat. You can also include spicy sausage instead of the regular Italian sausage. Just remember, the more the merrier in terms of toppings—so feel free to experiment!
