What a great idea and pizza anything is good in my book!
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!
Trying to lighten up on my carbs as we head into warmer months. This will be on my dinner menu this week!
OMG it really looks like pizza and has all those amazing flavors in it. The toppings are the best thing anyway!
love the roasted tomato sauce, it will be a staple from now on.
I love it too – it’s got such a better flavor compared to the jarred stuff!
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
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
I cannot have any tomato products. Can you suggest a substitute for me? I use a can of cream of chicken on top of spaghetti. Would that work here? Thank you for your help.
Instead of cream of chicken – I’d be more inclined to try Cheese Soup. Good luck! ~Jenn
