What exactly are meal prep dishes?

Meal prep dishes are nothing more than pre-cooked meals that you prepare in advance to last for 2–5 days. The advantages are obvious:

  • You save a lot of time

  • You automatically eat healthier and more consciously

  • Your wallet will thank you

  • No more stress with the eternal question "What shall I cook today?"

You can cook them in the traditional way, layer them in cold salads, or simply prepare them as individual components.

The 5 professional techniques for really good meal prep

You probably don't know these tricks yet—but they make the difference between okay and really good.

1. The layering technique for salads

(no more soggy food)

How to layer your salad correctly:

  1. Dressing all the way down

  2. Hard ingredients such as chickpeas or beans

  3. Carbohydrates such as rice or couscous

  4. Proteins

  5. Leaf lettuce at the top

2. Keep components separate

Always store sauces and crispy toppings separately—otherwise everything will get soggy.

3. The freshness kick on the day of consumption

Add just before serving: lemon, fresh herbs, avocado.

4. The right cooking methods

  • Roasting instead of frying → stays aromatic longer

  • Sous-vide or gentle preparation → stays juicy

  • Sauté briefly, then leave to cook in the oven.

5. Always season protein first

This keeps meat or tofu tasty even after several days.

The 5-day component trick (how to avoid boredom)

Here comes the game changer: On Sunday, you only need to prepare three ingredients and you can conjure up five completely different dishes.

Basic carbohydrate:

quinoa
