Why Make This Keto Meal Prep Dinner Low Carb Under 20g Net Carbs Easy
This recipe removes the stress of daily calorie counting and carb tracking. By preparing your meals in advance, you eliminate the temptation to grab high-carb takeout when you are tired.

Ingredients
- 1.5 lbs Chicken thighs, boneless and skinless, cut into bite-sized pieces
- 2 medium zucchinis, sliced into half-moons
- 1 large red bell pepper, chopped into 1-inch pieces
- 2 cups broccoli florets
- 3 tablespoons extra virgin olive oil
- 1 teaspoon garlic powder
- 1 teaspoon dried oregano
- 1/2 teaspoon smoked paprika
- Salt and black pepper to taste
- 1/4 cup basil pesto (ensure no added sugar)
- 1/4 cup grated Parmesan cheese
Directions
Step 1: Preparation
Preheat your oven to 400°F (200°C). Line a large rimmed baking sheet with parchment paper or a silicone baking mat for easy cleanup. Place the diced chicken thighs, sliced zucchini, bell peppers, and broccoli florets into a large mixing bowl. Drizzle the olive oil over the mixture and sprinkle with garlic powder, oregano, smoked paprika, salt, and pepper. Toss everything together until the chicken and vegetables are evenly coated with the oil and spices.
Step 2: Cooking
Spread the seasoned chicken and vegetable mixture across the prepared baking sheet in a single, even layer. Avoid overcrowding the pan so the vegetables roast rather than steam. Place the sheet pan in the center rack of the oven. Bake for 20 to 25 minutes, or until the chicken reaches an internal temperature of 165°F and the vegetables are tender and slightly charred at the edges. Remove from the oven and immediately dollop the pesto over the hot ingredients, tossing gently to combine.
Step 3: Plating
Divide the mixture equally into four airtight meal prep containers. Sprinkle each portion with a tablespoon of grated Parmesan cheese while the food is still warm. Allow the meals to cool to room temperature before sealing the lids. Store the containers in the refrigerator for up to four days. When you are ready to eat, simply reheat in the microwave for 90 seconds or in a skillet over medium heat until warmed through.
Expert Tips for Perfect Keto Meal Prep Dinner Low Carb Under 20g Net Carbs Easy
To get the best results, always use chicken thighs instead of chicken breasts. Thighs stay juicy and tender during reheating, whereas breasts can become dry and rubbery. Make sure your vegetables are cut into uniform sizes so they cook at the same rate. If you prefer your vegetables extra crispy, you can roast the chicken and broccoli for 10 minutes before adding the softer zucchini and peppers to the pan. Finally, always check your pesto label to ensure there are no hidden sugars or seed oils that could kick you out of ketosis.
Delicious Variations
You can easily swap the protein in this recipe to keep things interesting. Try using sliced smoked sausage or jumbo shrimp for a different flavor profile. If you want more heat, add a teaspoon of red pepper flakes to the seasoning mix. For a dairy-free version, simply omit the Parmesan cheese and ensure your pesto is vegan. You can also vary the vegetables by using asparagus, cauliflower, or green beans, as long as they fit within your daily carb limit.
Frequently Asked Questions
How long will this meal keep in the fridge?
These meals stay fresh and delicious for up to four days when stored in an airtight container in the refrigerator.

Can I freeze this keto meal prep?
Yes, you can freeze these portions for up to two months. However, be aware that zucchini can become slightly soft and watery upon thawing and reheating.
What is the best way to reheat this dish?
For the best texture, reheat in a skillet over medium heat for 5 minutes. If you are at work, a microwave for 1.5 to 2 minutes works perfectly well.
Can I use frozen vegetables instead of fresh?
You can, but fresh vegetables provide a much better crunch. If using frozen, roast them at a higher temperature (425°F) to help evaporate the extra moisture.
How do I lower the carb count even further?
To reduce the carbs even more, swap the red bell peppers for more green leafy vegetables or extra broccoli, as peppers contain slightly more natural sugar.
