Why You’ll Love These Meatballs

Ordinary meatballs are fine. But stuffed meatballs? They’re a revelation. Imagine cutting into a tender, juicy, herb-infused sphere of beef and spinach – only to have a river of warm, stretchy mozzarella spill out. That’s what we’re making today.

These meatballs are designed for the keto lifestyle: zero breadcrumbs, no hidden sugars, and plenty of fat to keep you satisfied. The spinach adds moisture, color, and a dose of vitamins without altering the classic Italian flavor profile. And the best part? Each meatball contains a hidden cube of mozzarella that melts into a glorious core – a surprise in every bite.

Whether you serve them over zucchini noodles, alongside a crisp Caesar salad, or simply with a sugar-free marinara for dipping, these meatballs will become a staple in your low-carb rotation.

Ingredients

For the Meatballs

• 1 lb (450 g) ground beef (80/20 or 85/15 – don’t go leaner; fat is flavor on keto)

• ½ lb (225 g) ground pork (adds moisture and richness)

• 1 cup (about 30 g) fresh spinach, finely chopped (or ½ cup frozen chopped spinach, thawed and squeezed dry)

• ½ cup (50 g) fine almond flour (the keto substitute for breadcrumbs)

• ¼ cup (25 g) finely grated Parmesan cheese (the sharp, dusty kind from a can or fresh – both work)

• 1 large egg, lightly beaten (binder)

• 2 cloves garlic, minced (or 1 tsp garlic powder)

• 1 teaspoon dried oregano

• 1 teaspoon dried basil

• ½ teaspoon red pepper flakes (optional, for gentle heat)

• 1 teaspoon salt

• ½ teaspoon black pepper

For the Stuffing

• 4 oz (115 g) low-moisture mozzarella cheese, cut into 12 small cubes (about ⅓ inch each – keep them cold!)

For Cooking & Serving (Optional)

• 2 tablespoons avocado oil or ghee (for pan-searing)

• ½ cup sugar-free marinara sauce (check labels – Rao’s Homemade is excellent)

• Fresh basil or parsley, for garnish
