Keto Pizza Stuffed Meatballs – A Fun Low-Carb Comfort Food
If pizza night and meatballs had a low-carb baby, this would be it. These Keto Pizza Stuffed Meatballs are juicy, cheesy, and packed with classic pizzeria flavors without the carb-heavy crust. They’re weeknight-friendly, party-ready, and a great way to satisfy cravings on a keto or low-carb plan.
Serve them over zucchini noodles, with a crisp salad, or simply on their own with extra sauce for dipping. They reheat well, freeze well, and taste like a little win every time you pull them out of the oven.
Ingredients
Method
- Preheat the oven: Set to 400°F (200°C). Line a sheet pan with parchment or lightly grease a baking dish.
- Make the meat mixture: In a large bowl, mix ground meat, egg, Parmesan, almond flour, onion powder, garlic powder, oregano, basil, red pepper flakes, salt, and pepper. Use your hands to combine gently. Don’t overmix.
- Prep the fillings: Cut mozzarella into small cubes. If using pepperoni, chop into small bits.
- Form the meatballs: Scoop about 2 tablespoons of the meat mixture into your hand. Flatten slightly, place a mozzarella cube (and a little pepperoni) in the center, then wrap the meat around it to seal completely. Roll to smooth. Repeat with the rest.
- Arrange and bake: Place meatballs on the prepared pan with a bit of space between them. Bake for 15 minutes.
- Add sauce: Remove from the oven, spoon marinara around and lightly over the meatballs. Return to the oven for 8–10 more minutes, until the centers reach 160°F and the cheese is melty.
- Finish and serve: Rest 5 minutes. Garnish with chopped parsley or basil. Serve with extra sauce and a sprinkle of Parmesan.

How to Make It
- Preheat the oven: Set to 400°F (200°C). Line a sheet pan with parchment or lightly grease a baking dish.
- Make the meat mixture: In a large bowl, mix ground meat, egg, Parmesan, almond flour, onion powder, garlic powder, oregano, basil, red pepper flakes, salt, and pepper. Use your hands to combine gently.
Don’t overmix.
- Prep the fillings: Cut mozzarella into small cubes. If using pepperoni, chop into small bits.
- Form the meatballs: Scoop about 2 tablespoons of the meat mixture into your hand. Flatten slightly, place a mozzarella cube (and a little pepperoni) in the center, then wrap the meat around it to seal completely.
Roll to smooth. Repeat with the rest.
- Arrange and bake: Place meatballs on the prepared pan with a bit of space between them. Bake for 15 minutes.
- Add sauce: Remove from the oven, spoon marinara around and lightly over the meatballs.
Return to the oven for 8–10 more minutes, until the centers reach 160°F and the cheese is melty.
- Finish and serve: Rest 5 minutes. Garnish with chopped parsley or basil. Serve with extra sauce and a sprinkle of Parmesan.
How to Store
- Refrigerator: Store in an airtight container with sauce for up to 4 days.
The sauce helps keep them moist.
- Freezer: Cool completely, then freeze on a parchment-lined tray. Once solid, transfer to a freezer bag. Freeze up to 2 months.
- Reheat: Thaw overnight in the fridge if frozen.
Warm in a 325°F oven for 12–15 minutes or microwave in short bursts until hot. Add a splash of sauce if they seem dry.
Health Benefits
- Low in carbs: Swapping breadcrumbs for almond flour keeps net carbs low while adding texture and healthy fats.
- High in protein: Ground meat and cheese provide steady, satisfying protein that helps with satiety and blood sugar control.
- Balanced fats: Parmesan and mozzarella add fat for energy on keto, while olive oil and almonds bring some monounsaturated fats and vitamin E.
- Portion control made easy: Individual meatballs make it simple to track servings and macros.
- Customizable for goals: Use leaner meat or reduce cheese for lower calories, or add more olive oil and cheese for higher fat macros.
What Not to Do
- Don’t overmix the meat: Overworking the mixture makes tough, rubbery meatballs.
- Don’t skip sealing the cheese: Any gaps will leak cheese onto the pan. Press seams tight and roll to smooth.
- Don’t use sugary sauce: Many jarred sauces hide sugar.
Choose a no-sugar-added marinara and read the label.
- Don’t overcrowd the pan: Crowding traps steam and prevents browning. Use two pans if needed.
- Don’t guess on doneness: Use a thermometer if you can. Aim for 160°F in the center.
Variations You Can Try
- Turkey or chicken: Use ground turkey or chicken for a lighter version.
Add 1 extra tablespoon olive oil for moisture.
- Hot and spicy: Swap mozzarella for pepper jack and add extra red pepper flakes or a dash of hot sauce to the meat.
- Supreme style: Tuck in a tiny piece of sautéed mushroom, olive, or bell pepper with the cheese for a loaded bite.
- Pesto twist: Mix 1–2 tablespoons basil pesto into the meat mixture and use provolone for a different flavor profile.
- Herb-forward: Add fresh chopped basil and parsley to the meat and finish with lemon zest for brightness.
- Dairy-light: Reduce mozzarella by half and use nutritional yeast in place of some Parmesan to keep flavor while cutting dairy.
FAQ
Can I make these in an air fryer?
Yes. Air fry at 375°F for 10–12 minutes until browned and cooked through. Warm the sauce separately on the stove and spoon over before serving.
What can I use instead of almond flour?
Finely ground pork rinds or a mix of pork rinds and Parmesan works well.
Coconut flour is more absorbent; if you try it, start with 1 to 1.5 teaspoons and adjust only if needed.
How do I keep the cheese from leaking out?
Use small cubes, seal the meat well, and chill formed meatballs for 10–15 minutes before baking if you have time. Avoid placing cheese too close to the edges.
Is marinara sauce keto-friendly?
It can be. Look for a no-sugar-added brand with simple ingredients like tomatoes, olive oil, garlic, and herbs.
Check the nutrition label for net carbs per serving.
Can I make them ahead?
Absolutely. Form the meatballs and refrigerate up to 24 hours before baking. You can also bake, cool, and store for easy reheating during the week.
What should I serve with them?
Try zucchini noodles, spaghetti squash, roasted broccoli, or a simple arugula salad with olive oil and lemon.
They’re also great as appetizers with toothpicks.
How many net carbs per serving?
It depends on your sauce and exact ingredients, but a typical serving of three meatballs with sauce often lands around 4–6g net carbs. Always calculate with your specific brands.
Can I cook them on the stovetop?
Yes. Brown them in a large skillet over medium heat in a little olive oil, turning to sear all sides.
Add sauce, cover, and simmer gently until cooked through, about 8–10 more minutes.
