Chef Jenn’s Tips

  • Ricotta adds such a lovely flavor to this dish, and the extra creaminess really puts it over the top.
  • Look for an Italian seasoning that has no hidden sugars or starches!
  • You can use sweet or hot Italian sausage in this recipe that’s perfect for keto and low carb diets.
  • You can use ground pork, chicken, or turkey instead of ground beef. Use what you’ve got!
  • Use this recipe for keto tomato sauce or buy a low-carb variety from the store.

What To Serve With this Casserole

This casserole is so hearty and meaty that you don’t need much with it. A simple salad with a killer dressing like this Green Goddess or Ranch Dressing would do the trick. Or, stick with a simple vegetable.

  2. 5 stars
    Perfect way to get all of my favorite flavors from pizza while staying on track. This will be going into our weekly dinner rotation. So good!

  3. 5 stars
    OMG it really looks like pizza and has all those amazing flavors in it. The toppings are the best thing anyway!

  4. For the keto pizza casserole, do you cover it while baking, or leave it uncovered?
    I haven’t rated it yet, as I haven’t baked the dish, yet.

    • It’s all going to depend on how deep your casserole dish is. If it’s very deep, cover it to start with then uncover for the last 10 minutes of baking. I usually just bake it uncovered. ~Jenn

  5. Curious on what size pan you used? I’m cooking for 2 with a little left over, but don’t want a ton of leftovers.

    • I make this in an 8×8-inch dish. There is 1.5 pounds of meat in it, so for 2 diners you’d likely have some leftovers. Freeze the leftovers and enjoy later! ~Jenn
