Now I know what you’re thinking, “low carb pizza!?” But hear me out… it is low carb but it’s also BOMB-Diggity (oh ya, I just brought that back…).

Because there’s no food as nostalgic as pizza… or a casserole for that matter, and what can beat combining both culinary delights and adding them to your recipe box of low carb dinners?!

How to Make Keto Pizza Casserole, Step-by-Step Photos

1. Sweet the zucchini by tossing it in salt and in a colander. Allow it to sit for 15 minutes, then rinse it off and remove excess liquid.

2. Cook the sausage in a pan with oil, breaking into small pieces as it cooks.

3. Combine the sausage, zoodles, pizza sauce, onions, bell peppers, and olives in a 9×13 casserole dish.

4. Cover the top of your casserole with cheese and pepperoni.

5. Bake in an oven preheated to 375 F for 20 minutes.

Best Ingredients To Use & Why

All the ingredients for this keto pizza are pretty standard! A few important notes to save you time and pizza carbs:

• Zucchini noodles – I like to buy pre-spiralized noodles to save time. Or, check out my guide to making zucchini noodles at home. Psst–you don’t need a spiralizer to do it, this veggie can be sliced into zucchini lasagna noodles and “rice” too.
• Sugar free pizza sauce – most store-bought sauces are LOADED with sugar, so check your labels or make your own.
• Keto cheese – don’t be shy here!

Storing Tips

Store any leftovers in the fridge and eat within 3 to 4 days, or freeze and enjoy later.

Can You Freeze This?

Absolutely! I LOVE using small resealable baggies to freeze individual portions.

Thaw in your fridge the night before you want to eat it and bake in the oven until it’s heated through.

Serving Recommendations

Pizza and keto salads are a classic combo — But, if you want to make sure you sop up ALL the sauce, I suggest whipping up a batch of my low carb garlic bread to ensure nothing goes to waste.

Recipe Variations

Currently, this casserole is loaded with all the supreme pizza toppings, but I’m a strong believer that no one should tell you how to top your pizza!

Here are a few topping variations so you can add your own low carb spin:

1. Meatlovers pizza. Turn this into a meatzza casserole by add ground beef, keto meatballs, sausage, etc. Bonus: most of these are no carb pizza ingredients!
2. Vegetable pizza. You can skip the meat for a vegetarian cheesy pizza casserole, or add in more vegetables, just dice and saute before. Eggplant pizza and keto cauliflower pizza are a few delicious veggies that come to mind.
3. Mexican pizza. Add in some of your taco favorites, like salsa and shredded chicken — take some notes from my keto Mexican casserole.

Lindsey's Tips

• Pizza sauce - Most storebought products are loaded with sugar. Opt for my homemade version or read labels carefully and find one without added sugar.
• Nutritional information is for 1 slice if you slice this casserole into 8 pieces:
