Prep your workspace: Line a sheet pan with parchment.
Set a large skillet over medium heat. Preheat your oven to 375°F (190°C) if finishing meatballs in the oven.
Mix the meatballs: In a bowl, combine ground meat, Parmesan, almond flour, egg, garlic, onion powder, Italian seasoning, red pepper flakes, salt, pepper, and parsley. Stir gently with a fork or your hands until just combined. Don’t overmix—that can make them tough.
Shape: Scoop into 1.5-inch balls (about 18–20 meatballs).
Lightly oil your hands to keep the mixture from sticking and to help form smooth balls.
Sear for flavor: Heat oil in the skillet. Sear meatballs in batches, turning to brown all sides. You’re looking for color, not full doneness.
Transfer browned meatballs to the lined sheet pan.
Finish in the oven: Bake 8–12 minutes, until the centers reach 160°F (71°C) for beef or beef/pork mix. Set aside to rest for 5 minutes.
Make the sauce: In the same skillet, melt butter over medium heat. Add garlic and cook 30–60 seconds until fragrant.
Pour in heavy cream and simmer 2–3 minutes to thicken slightly. Whisk in Parmesan and nutmeg. Season with salt and pepper.
If it gets too thick, splash in a bit more cream or broth.
Combine: Add the meatballs to the pan and toss gently in the sauce. Sprinkle with fresh parsley.
Prep your sides (optional): Quickly sauté zucchini noodles in olive oil for 1–2 minutes, or steam broccoli. Keep them crisp to avoid sogginess in meal prep.
Portion: Divide meatballs and sauce into 4 meal prep containers.
Add your chosen low-carb sides.
