Start by choosing simple meals you can repeat.

• Wash and chop vegetables
• Marinate or season proteins
• Measure out carbs if needed

This step saves a lot of time once you start cooking.

Step 4: Cook in Batches

Cook multiple foods at the same time.

For example:

• Bake chicken in the oven
• Cook rice or quinoa on the stove
• Roast vegetables on a tray

Batch cooking is the core of any weekly meal prep plan.

Step 5: Portion Your Meals

Once everything is cooked, divide it into containers.

• Add protein + carb + vegetables to each meal
• Keep portions balanced
• Prepare grab-and-go meals for busy days

If you’re using portion containers, this step becomes even easier.

Step 6: Store Properly

Store your meals so they stay fresh.

• Keep 3–4 days of meals in the fridge
• Freeze extra portions if needed
• Store snacks separately for easy access

A simple way to stay organized is labeling meals by day if needed.
