Ingredients Overview

Each ingredient in these Keto Mozzarella-Stuffed Mini Meatloaves serves a delicious and low-carb purpose.

Ground beef (or a beef/pork blend)
Use 80/20 ground beef for a juicy, flavorful texture. A beef and pork mix gives added richness, but either works well.

Shredded zucchini
Moistens the meat and adds hidden veggies without noticeable texture. Squeeze it well before mixing to avoid soggy loaves.

Egg
Binds the mixture without adding carbs. Just one is enough to hold it all together.

Parmesan cheese
Replaces breadcrumbs while adding salty, umami depth. Use finely grated for best texture.

Garlic and onion powder
These dried aromatics infuse flavor throughout without the moisture of fresh onions, keeping the meatloaf firm.

Italian seasoning
Adds herbaceous flavor. Feel free to use oregano, basil, or thyme if you don’t have a mix.

Salt and pepper
Essential for seasoning—don’t skip or skimp.

Mozzarella cheese (block form)
Cut into cubes and stuffed inside for a gooey center. Use low-moisture mozzarella for best melt and structure.

Sugar-free ketchup or tomato paste (optional glaze)
Adds a sweet-savory topping without the sugar spike. Optional, but adds a nostalgic flavor.

Optional: chopped parsley or red pepper flakes for garnish and kick.

Step-by-Step Instructions

1. Preheat oven and prep tin (5 minutes)
Preheat your oven to 375°F. Grease a muffin tin or line a baking sheet with parchment paper for free-form loaves.

2. Prepare the zucchini (5 minutes)
Grate 1 small zucchini (about 1 cup) and place in a clean towel. Squeeze out as much moisture as possible—this keeps the loaves from becoming watery.

3. Mix the meatloaf base (3 minutes)
In a large bowl, combine:
– 1½ lbs ground beef
– Grated, squeezed zucchini
– 1 egg
– ⅓ cup grated Parmesan cheese
– 1 tsp garlic powder
– 1 tsp onion powder
– 1 tsp Italian seasoning
– Salt and pepper to taste

Mix gently with hands or a spatula until just combined—don’t overmix.

4. Stuff with mozzarella (5 minutes)
Cut low-moisture mozzarella into ¾-inch cubes (about 12). Divide meat mixture into 12 equal portions. Flatten each portion in your hand, place a cheese cube in the center, and wrap the meat around it to form a sealed mini loaf.

5. Place and bake (20–22 minutes)
Arrange meatloaves in the muffin tin or on the baking sheet. Optional: top each with a teaspoon of sugar-free ketchup or tomato paste.

Bake for 20–22 minutes, or until the internal temperature reaches 160°F. Broil for 1–2 minutes at the end for a browned top if desired.

6. Rest and serve (3–5 minutes)
Let the meatloaves rest for 5 minutes before serving. Garnish with parsley or chili flakes if using.

Common mistakes to avoid:
– Don’t skip squeezing zucchini—it will release water as it cooks.
– Seal the mozzarella well inside the meat to avoid leakage.
– Don’t overbake—use a meat thermometer for perfect results.

FAQs

1. Can I freeze these mini meatloaves?
Yes. Let them cool completely, wrap individually, and freeze for up to 3 months. Reheat in the oven or microwave.

2. What’s the best cheese for stuffing?
Low-moisture mozzarella works best. It melts well and stays inside. You can also use cheddar, provolone, or pepper jack.

3. Can I use a loaf pan instead?
You can, but the center may cook unevenly and the cheese may not stay in place. Mini loaves or muffin tins are best for consistent results.

4. Are these good for meal prep?
Absolutely. Store in airtight containers in the fridge for up to 5 days. Reheat in the microwave or oven.

5. Can I leave out the zucchini?
Yes, but the loaves may be drier. If skipping, add a tablespoon of heavy cream or mayo to keep moisture in.

6. How do I prevent the cheese from leaking out?
Fully seal the meat around the cheese. Flatten and fold carefully, pinching any openings shut.

7. What can I serve with these on a keto diet?
Try with cauliflower mash, sautéed spinach, or a keto slaw. Any low-carb veggie side will work well.
