Frequently Asked Questions
What marinara is keto-friendly?
Rao’s Homemade is the gold standard (3g net carbs per ½ cup). Avoid brands with added sugar — check the label.
Can I use ground turkey or chicken?
Yes — add 1 tbsp olive oil to the mix for moisture since lean meats dry out faster.
How do meatballs hold without breadcrumbs?
The egg and Parmesan bind them. Don’t overmix — gently combine until just together.
Can I use frozen meatballs?
Yes — check the carb count. Place frozen in the dish, add 5 minutes to baking time before adding sauce.
What to serve with it?
Zucchini noodles, spaghetti squash, a Caesar salad, or garlic bread (non-keto guests). It’s filling enough on its own.
Can I freeze the casserole?
Yes — assemble without cheese, freeze up to 2 months. Add cheese and bake from frozen at 375°F for 40 minutes.
How many net carbs per serving?
About 5g net carbs per serving (with Rao’s marinara). Serves 6.
Can I add vegetables?
Spinach, sliced mushrooms, or roasted bell peppers work under the cheese layer. Add before the sauce step.
