Step‑by‑Step Instructions for Low Carb Zucchini and Sausage Casserole
Step 1: Preheat the Oven
Begin by preheating your oven to 375°F (190°C). This will ensure that your Low Carb Zucchini and Sausage Casserole bakes evenly and at the right temperature, helping the flavors to meld beautifully while allowing the cheese to melt to perfection.
Step 2: Sauté the Onions
In a large skillet, heat a drizzle of olive oil over medium heat. Add the diced onion and sauté for about 3–4 minutes until it turns translucent and fragrant. This step creates a sweet, flavorful base that will enhance the overall taste of your casserole.
Step 3: Add Garlic
Next, add the minced garlic to the skillet and sauté for an additional minute, stirring constantly to avoid burning. You’ll know it’s ready when the kitchen is filled with a warm, aromatic scent. This fragrant addition will elevate the dish’s flavor profile significantly.
Step 4: Cook the Sausage
Crumble the Italian sausage into the skillet and cook it thoroughly for about 5–7 minutes, stirring occasionally until it’s browned and no longer pink. This step is crucial as it infuses the sautéed vegetables with savory depth, making your Low Carb Zucchini and Sausage Casserole truly delicious.
Step 5: Stir in Peppers and Herbs
After the sausage is cooked, stir in the diced bell peppers, dried oregano, and basil. Continue cooking for another 2–3 minutes until the peppers are just tender. Season the mixture with salt and black pepper to taste—this combination adds vibrant color and flavor to your casserole.
Step 6: Layer the Zucchini
In a greased baking dish, start layering half of the sliced zucchini at the bottom. Spread it out evenly to create a solid base. This will help absorb the juices from the sausage mixture as it cooks, keeping your Low Carb Zucchini and Sausage Casserole moist and flavorful.
Step 7: Add Sausage Mixture
Spread the delicious sausage mixture over the layer of zucchini. Take care to distribute it evenly so that every bite incorporates the savory flavors of the sausage and vegetables. This step is where the magic happens, with layers blending beautifully in the oven.
Step 8: Top with Remaining Zucchini
Next, add the remaining slices of zucchini on top of the sausage mixture, arranging them in a neat layer. This not only adds visual appeal but also helps keep the casserole’s layers distinct while cooking, ensuring a delightful presentation when served.
Step 9: Sprinkle the Cheese
Generously sprinkle the mozzarella cheese over the top of the zucchini layer, followed by the grated Parmesan cheese. This cheesy topping will create a wonderfully gooey and crispy crust as it bakes, making your Low Carb Zucchini and Sausage Casserole irresistible.
Step 10: Bake Covered
Cover the baking dish with aluminum foil and place it in the preheated oven. Bake for 20 minutes to allow the flavors to meld and the vegetables to soften. This step is essential to ensure that the casserole cooks evenly without drying out.
Step 11: Bake Uncovered
After 20 minutes, carefully remove the foil and continue baking for an additional 10–15 minutes until the cheese is golden and bubbly. Keep an eye on it during the last few minutes to achieve that perfect crust for your Low Carb Zucchini and Sausage Casserole.
Step 12: Rest and Serve
Once done, remove the casserole from the oven and let it rest for 5 minutes to allow the layers to set properly. This resting time enhances the flavors and makes it easier to serve. Then, scoop out portions and delight in the comforting goodness of your accomplished dish!

Low Carb Zucchini and Sausage Casserole Recipe FAQs
How do I select the best zucchini for this casserole?
Absolutely! When choosing zucchini, look for firm ones with a shiny skin, and avoid any with dark spots or blemishes. Smaller zucchinis tend to be sweeter and more tender, making them ideal for slicing and layering in your Low Carb Zucchini and Sausage Casserole.
How long can I store leftovers in the refrigerator?
You can store leftovers in an airtight container in the refrigerator for up to 4 days. When you’re ready to enjoy it again, simply reheat individual portions in the microwave or oven until they’re heated through and deliciously melty.
Can I freeze the casserole? If so, how?
Very! To freeze your Low Carb Zucchini and Sausage Casserole, first, let it cool completely after baking. Then, cut it into individual portions and wrap each securely in plastic wrap, followed by aluminum foil to prevent freezer burn. Store them in a freezer-safe container for up to 3 months. When you’re ready to enjoy, thaw overnight in the refrigerator before reheating.
What should I do if my casserole turns out watery?
If you find your casserole is too watery, it may be due to excessive moisture from the zucchini. To avoid this next time, I recommend salting the zucchini slices and letting them sit for about 15 minutes before layering them in the casserole. This helps draw out some moisture. You can also increase baking time by a few minutes to allow extra liquid to evaporate.
Are there any dietary considerations for this recipe?
Absolutely! This recipe is naturally gluten-free and low in carbs, making it suitable for those following a ketogenic or low-carb diet. However, if you’re cooking for anyone with allergies, ensure they are not sensitive to any of the ingredients, particularly the sausage or cheese. For those looking to reduce fat, using turkey or chicken sausage is a great alternative!
