Why Make This Keto Meal Prep Lunch Low Carb Under 20g Net Carbs Easy
The primary reason to love this recipe is its simplicity. You don’t need fancy equipment or hard-to-find ingredients to make a meal that tastes like it came from a gourmet cafe. It is specifically designed to be “fridge-stable,” meaning the flavors actually meld and improve after a day or two of storage. Most importantly, it clocks in at only 6g of net carbs, giving you plenty of room for your keto breakfast and dinner. It hits that perfect balance of healthy fats, lean protein, and fiber-rich vegetables to keep you full until your next meal.
Ingredients
- 1.5 lbs Chicken breast, cut into 1-inch cubes
- 4 medium Zucchinis, spiralized (or 2 pre-packaged bags of zoodles)
- 1/2 cup High-quality basil pesto (check for no added sugar)
- 1 cup Cherry tomatoes, halved
- 2 tbsp Extra virgin olive oil
- 1/2 cup Shredded parmesan cheese
- 1 tsp Garlic powder
- Salt and black pepper to taste
- Optional: Crushed red pepper flakes for heat
Directions
Step 1: Preparation
Start by spiralizing your zucchinis if you are using fresh whole vegetables. Place the zucchini noodles in a large bowl and sprinkle them with a pinch of salt. Let them sit for 5 minutes, then pat them dry with a paper towel to remove excess moisture. This prevents your meal prep from becoming watery later. Chop your chicken breast into bite-sized pieces and season them generously with garlic powder, salt, and pepper.
Step 2: Cooking
Heat the olive oil in a large skillet over medium-high heat. Add the seasoned chicken pieces in a single layer. Cook for about 6-8 minutes, turning occasionally, until the chicken is golden brown and cooked through (internal temperature of 165°F). During the last two minutes of cooking, add the halved cherry tomatoes to the pan just until they begin to soften. Remove the skillet from the heat.
Step 3: Assembly
In a large mixing bowl, toss the cooked chicken and tomatoes with the zucchini noodles. Add the basil pesto and fold everything together until the ingredients are evenly coated. Divide the mixture into four airtight meal prep containers. Top each container with 2 tablespoons of shredded parmesan cheese and a sprinkle of red pepper flakes if you enjoy a little kick.
Expert Tips for Perfect Keto Meal Prep Lunch Low Carb Under 20g Net Carbs Easy
To avoid the “soggy zoodle” syndrome, do not overcook the zucchini. In fact, many keto experts recommend keeping the zucchini noodles raw when you pack them; the heat from reheating the chicken later will soften them perfectly. Also, always check your pesto labels. Many store-bought brands use sunflower or canola oil and added sugars. Look for brands that use olive oil or avocado oil to keep your fats healthy and your carb count low.
Delicious Variations
- Creamy Pesto: Stir in 2 tablespoons of heavy cream or softened cream cheese to the pesto for a richer sauce.
- Protein Swap: Replace the chicken with large shrimp or sliced Italian sausage links for a different flavor profile.
- Dairy-Free: Omit the parmesan cheese and use a nutritional yeast-based pesto to make this recipe completely paleo and dairy-free.
- Crunch Factor: Add a tablespoon of toasted pine nuts or crushed walnuts to the top of each container before serving.
Frequently Asked Questions
How long does this lunch stay fresh in the fridge?
When stored in an airtight container, this keto meal prep lunch stays fresh and delicious for up to 4 days. After the fourth day, the zucchini may begin to release more water, making the dish slightly softer.

Can I freeze this recipe?
We do not recommend freezing zucchini noodles, as their high water content causes them to become mushy and lose their texture once thawed. This recipe is best enjoyed fresh or from the refrigerator.
Do I have to reheat it, or can I eat it cold?
This dish is incredibly versatile! It tastes great when reheated in the microwave for 60-90 seconds, but many people actually prefer it cold as a “zoodle pasta salad,” especially during the summer months.
What if I don’t have a spiralizer?
No problem at all! You can use a vegetable peeler to create thin ribbons, or simply dice the zucchini into small cubes and sauté them. Most grocery stores also sell pre-spiraled zucchini in the produce or frozen section.
Is this recipe suitable for a strict keto diet?
Absolutely. With only 6g of net carbs per serving, it fits perfectly within the macros of a strict ketogenic diet. It focuses on whole food ingredients and healthy fats, which are the cornerstones of successful ketosis.
