Why Make This Keto Meal Prep Chicken Low Carb Under 20g Net Carbs Easy
This recipe removes the guesswork from your diet. When you have a pre-portioned, keto-friendly meal waiting in the fridge, you are much less likely to reach for high-carb convenience foods. It uses accessible ingredients found at any grocery store and requires only one sheet pan, which means minimal cleanup. Furthermore, this meal is naturally gluten-free and dairy-free, making it an excellent choice for various dietary sensitivities while packing a massive protein punch to support muscle maintenance.
Ingredients
- 1.5 lbs Boneless, skinless chicken breasts, cut into 1-inch cubes
- 2 cups Broccoli florets, bite-sized
- 1 Large zucchini, sliced into half-moons
- 1 Red bell pepper, chopped into chunks
- 3 tbsp Extra virgin olive oil or avocado oil
- 1 tsp Garlic powder
- 1 tsp Onion powder
- 1 tsp Smoked paprika
- 1/2 tsp Dried oregano
- 1/2 tsp Sea salt
- 1/4 tsp Black pepper
- Optional: Lemon wedges and fresh parsley for garnish
Directions
Step 1: Preparation and Preheating
Preheat your oven to 400°F (200°C). Line a large rimmed baking sheet with parchment paper or a silicone baking mat to prevent sticking. Wash all your vegetables thoroughly. Chop the chicken into even cubes to ensure they cook at the same rate. Slice the zucchini, chop the bell pepper, and break the broccoli into small florets.
Step 2: Seasoning the Ingredients
Place the cubed chicken and all the chopped vegetables into a large mixing bowl. Drizzle the olive oil over the top. In a small ramekin, mix the garlic powder, onion powder, smoked paprika, oregano, salt, and pepper. Sprinkle the seasoning mix over the chicken and veggies. Toss everything together with your hands or large spoons until every piece is evenly coated in oil and spices.
Step 3: Roasting to Perfection
Spread the mixture in a single layer across the prepared baking sheet. Ensure the pieces are not overcrowded; use two pans if necessary to allow the air to circulate for better browning. Place the tray in the center rack of the oven. Bake for 20 to 25 minutes, or until the chicken reaches an internal temperature of 165°F (74°C) and the vegetables are tender-crisp with slightly charred edges.
Step 4: Portioning and Storage
Remove the pan from the oven and let it cool for about 5 to 10 minutes. Divide the mixture evenly into four airtight meal prep containers. If you prefer, add a fresh lemon wedge to each container for a burst of acidity right before eating. Seal the containers and store them in the refrigerator for up to four days.
Expert Tips for Perfect Keto Meal Prep Chicken Low Carb Under 20g Net Carbs Easy
- Uniform Cutting: Cut your chicken and vegetables into similar sizes so they finish cooking at exactly the same time.
- Check Temperature: Use an instant-read meat thermometer to avoid overcooking the chicken. Chicken breast dries out quickly if it goes past 165°F.
- Glass Containers: Use glass airtight containers for storage. They keep the food fresher than plastic and are safer for microwave reheating.
- Don’t Overcrowd: If the pan is too full, the vegetables will steam instead of roast. Space them out for that perfect roasted texture.
Delicious Variations
- Spicy Kick: Add 1/2 teaspoon of red pepper flakes or a dash of cayenne pepper to the seasoning mix.
- Pesto Style: Skip the dried spices and toss the cooked chicken and veggies in 2 tablespoons of sugar-free basil pesto before portioning.
- Cheesy Delight: Sprinkle 1/4 cup of grated Parmesan cheese over the tray during the last 5 minutes of baking.
- Asian-Inspired: Swap the olive oil for sesame oil and use ginger powder and coconut aminos instead of paprika and oregano.
Frequently Asked Questions
How long does this meal prep stay fresh?
When stored in airtight containers in the refrigerator, this chicken and vegetable mix stays fresh and delicious for up to 4 days. It is perfect for a Monday-through-Thursday lunch rotation.

Can I use chicken thighs instead of breasts?
Yes, you can swap chicken breasts for boneless, skinless chicken thighs. Thighs are more forgiving and remain juicier after reheating, though they do contain slightly more fat and calories.
What is the best way to reheat this meal?
For the best results, reheat in a microwave-safe dish for 1.5 to 2 minutes. Alternatively, you can toss the contents into a hot skillet for 3 to 5 minutes to crisp up the vegetables again.
Can I freeze these meals?
While you can freeze this recipe, the texture of the zucchini and bell peppers may become slightly soft or watery upon thawing. If you plan to freeze, consider using heartier vegetables like green beans or cauliflower.
Is this recipe really under 20g net carbs?
Absolutely. By using low-carb vegetables like broccoli and zucchini and avoiding sugary marinades, this entire serving comes in at approximately 5g net carbs, leaving you plenty of room for other meals during the day.
