Baking the meatballs on a sheet pan rather than frying them in batches on the stovetop is what makes a large batch realistic for meal prep - twenty meatballs take the same oven space as four. Spiralized zucchini stands in for pasta, keeping the whole thing low-carb while still delivering the classic marinara-and-parmesan combination.

Preheat the oven to 200°C (400°F) and line a baking sheet with parchment paper.
In a large bowl, combine the ground beef, breadcrumbs, egg, grated parmesan, minced garlic, chopped parsley, salt, and black pepper. Mix gently until just combined - overmixing makes tough meatballs.
Roll the mixture into evenly sized balls, about 2.5cm in diameter, and place on the baking sheet.
Bake for 18-20 minutes, until browned and cooked through, reaching an internal temperature of 71°C (160°F).
While the meatballs bake, heat the marinara sauce in a saucepan over medium-low heat until warmed through.
Using a spiralizer, turn the zucchini into noodle-like strands. Saute in a lightly oiled pan over medium heat for 2-3 minutes, until just tender but not mushy.
Divide the zucchini noodles, meatballs, and warm marinara sauce evenly among meal-prep containers.
Top with extra grated parmesan before sealing.
Don't Overmix the Meatball Mixture: Handling the mixture too much develops the proteins in the meat and makes the meatballs dense rather than tender - mix just until combined. Don't Overcook the Zucchini Noodles: They release water and turn mushy quickly, so a brief 2-3 minute saute right before packing is enough - many people skip cooking them entirely and let the hot meatballs and sauce warm them through. Bake, Don't Pan-Fry, for Larger Batches: Baking all the meatballs at once on a sheet pan is far more efficient than frying them in multiple batches when prepping a large quantity for the week.
Store the meatballs and marinara together for up to 4 days, but keep the zucchini noodles separate and add them fresh each day, since they release water and turn watery if stored under warm sauce too long.

Souvlaki traditionally means skewered and grilled, but for a batch of meal-prep boxes it's easier to cook the marinated chicken in one pan rather than threading and turning individual skewers five times over. The lemon-oregano marinade and quick tzatziki are what carry the Greek flavor here, whether the chicken hits a grill or a skillet.

Skipping the beans is what actually keeps a chili keto, since they're usually the biggest carb contributor in a traditional recipe - the beef, tomatoes, and spices carry all the flavor on their own. Riced cauliflower sits underneath as a low-carb stand-in for rice, soaking up the chili's juices instead of turning it into a separate side.

A Buddha bowl is really just a template - a grain, a roasted vegetable, a protein, and a sauce, arranged rather than mixed. Roasting the sweet potato and crisping the chickpeas together on one sheet pan keeps this genuinely simple to batch, while the tahini dressing ties every component together once the containers are opened for lunch.

Baking the chicken breasts all at once on a single sheet pan, rather than pan-searing them individually, is what makes this genuinely scalable for a week of lunches - five or six breasts take the same hands-on effort as one. Brushed with barbecue sauce in the final minutes so it caramelizes rather than burns, this is built to portion straight into containers alongside rice and vegetables.
