Ingredients for Keto Pizza Casserole

Grab these simple ingredients – I bet you have most in your fridge already! The key is quality here:

• 1 lb ground beef (80% lean) – That extra fat keeps it juicy and keto-friendly
• 1 cup sugar-free marinara sauce – My go-to is Rao’s Homemade (worth the splurge!)
• 1 cup shredded mozzarella – Full-fat only please – the stringier the better!
• ½ cup grated Parmesan – The real stuff in the green can works great
• ½ cup sliced pepperoni – Get the mini ones for perfect coverage
• 1 tsp Italian seasoning – Or mix your own with oregano, basil, thyme
• ½ tsp each garlic & onion powder – The flavor boosters!

See? Nothing weird – just real food that makes magic together.

Equipment You’ll Need

Don’t stress – you probably have everything already! Here’s what I use:

• 10-inch skillet – For browning that beef to perfection
• 8×8 baking dish – My trusty Pyrex works great
• Oven – Set that baby to 375°F and you’re golden

Bonus tip: If you’ve got an oven-safe skillet, you can brown and bake in the same pan – fewer dishes to wash! Now let’s get cooking.

How to Make Keto Pizza Casserole

Okay, let’s dive into the fun part – making this cheesy masterpiece! I promise it’s so easy you could do it half-asleep (though I don’t recommend cooking while napping). Follow these simple steps and you’ll have keto pizza magic in no time.

Step 1: Cook the Ground Beef

First things first – get that beef sizzling! Crank your skillet to medium heat and crumble in the ground beef. Listen for that satisfying sizzle – that’s how you know it’s working. Keep breaking it up with your spatula until it’s nicely browned, about 5-7 minutes. Here’s my pro tip: tilt the skillet and spoon out the extra grease (save it for cooking veggies later!). Don’t overcook it though – we want juicy bits, not dry little pebbles.

Step 2: Layer the Casserole

Now for the flavor party! Stir in your marinara sauce and all those yummy seasonings until the beef is perfectly coated. Pour this saucy goodness into your baking dish – I like to give it a little shake to spread evenly. Then comes the best part – the CHEESE! Sprinkle that mozzarella like you’re making it rain in a dairy club. Follow up with the Parmesan for that extra savory punch. Top it all off with pepperoni – arrange them like little edible tiles or just toss them on willy-nilly (I won’t judge).

Step 3: Bake to Perfection

Slide that beauty into your preheated oven (middle rack is perfect) and let the magic happen. Set your timer for 20 minutes, but start peeking around 15 – you’ll know it’s done when the cheese is gloriously bubbly with those little golden-brown spots we all love. Pro tip: If you want extra crispy pepperoni, broil for the last minute – just don’t walk away, it burns fast! Let it cool for 5 minutes (the hardest wait of your life) so the cheese sets up nicely before digging in.

Tips for the Best Keto Pizza Casserole

Want to take your casserole from good to “Oh my gosh, give me the recipe!” status? Here are my hard-earned secrets:

• Pat that beef dry after browning – excess moisture makes the sauce runny
• Full-fat cheese only – skim versions don’t melt right and have hidden carbs
• Let it rest 5 minutes – I know it’s tempting, but this keeps the layers perfect
• Broiler finish – 30 seconds at the end gives pepperoni that crispy curl we all crave

Trust me, these tiny tweaks make a huge difference in your final dish!

Ingredient Substitutions & Variations

Look, I know we all have those “oh no, I’m out of ____” moments. Don’t panic – this recipe is crazy flexible! Here’s how to mix it up while staying keto:

• Meat swap: Ground turkey or Italian sausage work great – just check for added sugars in sausage
• Veggie boost: Toss in sautéed mushrooms, bell peppers, or spinach (squeeze out excess water first!)
• Dairy-free: Use vegan mozzarella shreds and omit Parmesan (check carb counts though)
• Spice it up: Add red pepper flakes or swap pepperoni for spicy chorizo

The key is keeping total carbs under 8g per serving – my rule of thumb is max ½ cup extra veggies. Get creative – it’s your pizza after all!

Serving Suggestions

This casserole shines all on its own, but if you want to make it a full meal, here’s how I love to serve it:

• Garlic butter broccoli – The perfect green companion to all that cheesy goodness
• Crisp Caesar salad – Skip the croutons and enjoy that crunchy contrast
• Zucchini noodles – Tossed with pesto for an Italian twist

My family’s favorite? A simple side of pickled jalapeños – that spicy kick cuts right through the richness!

Storage and Reheating Instructions

Okay, real talk – this casserole disappears fast in my house! But if you miraculously have leftovers, here’s how to keep them tasting fresh:

• Fridge: Store in an airtight container for up to 3 days – the cheese still melts beautifully when reheated!
• Oven reheat: 350°F for 10-15 minutes (cover with foil to prevent drying)
• Microwave: 1-minute bursts, stirring between, until heated through

Pro tip: Add fresh pepperoni when reheating for that just-baked crispiness. And yes, it tastes even better the next day!

Keto Pizza Casserole Nutrition Facts

FAQs About Keto Pizza Casserole

I get questions about this recipe all the time – here are the most common ones with my tried-and-true answers:

• Can I freeze this casserole? Absolutely! Let it cool completely, then wrap tightly in foil or store in an airtight container. It keeps beautifully for up to 2 months. To reheat, thaw overnight in the fridge and bake at 350°F until bubbly (about 20 minutes).
• Is marinara sauce really keto? Only if it’s sugar-free! Always check labels – many brands sneak in sugar. My favorite is Rao’s Homemade (just 3g net carbs per ½ cup). When in doubt, make your own with canned tomatoes and Italian herbs!
• Can I use chicken instead of beef? You sure can! Diced chicken thighs work great – just brown them first like you would the beef. For extra flavor, toss in some extra Italian seasoning while cooking.
• Why is my casserole watery? Two likely culprits: your marinara had too much liquid, or you didn’t drain the beef well enough. Next time, pat the cooked meat dry with paper towels and opt for a thicker sauce.

Got more questions? Just ask – I’ve made this recipe so many times I could probably do it in my sleep!
