What Goes With Keto Casserole?

The best choice to serve alongside a casserole like this is a nice big side salad. It cuts the richness of the meat and sauce but keeps it low-carb.

If you want to add a traditional bread side to this, you can do something like make this 90-second keto bread and toss some garlic salt with it to add more flavor.

How to Make a Keto Pizza Casserole

Video Recipe:

Start by slicing and chopping the vegetables and pitting the olives if needed. It makes the process easier when you have everything ready before you start cooking.

Preheat the oven to 400°F/200°C and spray a 10" or 9"x13" baking dish with non-stick spray and set it aside.

In a large skillet, heat the olive oil over medium heat, then add the chopped bacon to the pan. Cook for 4 to 5 minutes.

Frequently Asked Questions

How Many Carbs are in Pizza Casserole?

When it comes to the carbs in this pizza casserole, the final carb count will depend on what ingredients you use. If you are following the ingredients list and choosing the lowest carb count possibly, as well as making sure it is no sugar added, this casserole comes in at about 12 carbs.

I recommend choosing a sugar-free tomato sauce and making sure that the sausage you use is also sugar-free to guarantee the lowest possible carbs.

What Vegetables Can I Add and Stay Keto?

There are a lot of low-carb vegetables that you can add to this keto pizza casserole. I love adding mushrooms, onions, bell peppers, and olives. You could also add some spinach or other greens. Other ideas are zucchini, eggplant, and artichokes.

Can Keto Pizza Casserole Be Made Ahead of Time?

This keto pizza casserole can be made ahead of time and reheated when you are ready to serve it. I like to make a big batch on the weekend and then have it for lunch or dinner during the week. It reheats really well!

Another idea is to get the casserole to the baking step and then place it in the refrigerator. Once you are ready to enjoy it, place it in the oven and bake according to the directions. It's good for 3 to 4 days in the refrigerator.

How Do I Freeze Keto Pizza for Later?

If you have leftovers or want to make a big batch ahead of time, this casserole freezes really well. I like to portion it into individual servings and then place them in the freezer. That way I can just grab one when I want it and don’t have to worry about reheating the whole thing.

Once the casserole has cooled completely, place the portions in airtight containers. Use either freezer bags or freezer-safe airtight containers. The keto pizza casserole will last for up to 3 months.

When you are ready to serve, place the pizza in the refrigerator and let it thaw overnight. You can also reheat the keto pizza casserole from frozen, but be careful not to overheat some sections while leaving others still frozen.
