For the Base

How to Make Keto Pizza Casserole Recipe
Step 1: Prepare the Zucchini
Sprinkle the zucchini with salt and let it drain for 30 minutes. After draining, squeeze out any excess moisture and place it in a medium bowl.
Step 2: Cook the Sausage
In a skillet over medium heat, cook the sausage until fully cooked through. Break up any clumps with the back of a wooden spoon. This should take about 8 minutes. Use a slotted spoon to transfer the cooked sausage to the bowl with zucchini.
Step 3: Combine Ingredients
Stir together the sausage and zucchini until well mixed. Spread this mixture into a small casserole dish or divide it between two 8-ounce ramekins.
Step 4: Add Sauce and Toppings
Spoon marinara sauce over the sausage mixture evenly. Layer on cheese and toppings as desired. Save some cheese to sprinkle on top so that the toppings stay in place.
Step 5: Cook Your Casserole
Air fry at 350ºF for 8 to 12 minutes or bake in a preheated oven at 375ºF for about 10 to 15 minutes until everything is bubbling and golden brown.

Common Mistakes to Avoid
Making the perfect Keto Pizza Casserole Recipe can be easy, but there are common pitfalls to watch out for.
- Overlooking zucchini moisture: Failing to drain the shredded zucchini can lead to a soggy casserole. Always salt and let it drain before using.

- Skipping the cheese layer: Neglecting to save some cheese for the top can result in toppings that don’t stay in place. A little sprinkle helps everything stick together nicely.
- Ignoring cooking time: Cooking for too long can dry out your casserole. Keep an eye on it in the oven or air fryer to ensure it’s perfectly melted and bubbly.
- Not customizing toppings: Sticking strictly to the recipe may limit flavor. Feel free to add your favorite low-carb toppings like olives or different meats.
