Method

1️⃣ Preheat

Preheat your oven to 200°C and line an oven-safe baking dish with baking paper.

2️⃣ Prepare the Egg Base

In a large bowl, whisk the eggs until smooth and slightly frothy.

3️⃣ Add the Vegetables

Add the onion, zucchini, capsicum, tomatoes and spinach to the baking dish.
Pour the whisked eggs over the vegetables.

4️⃣ Mix the Protein

In a separate bowl, combine the collagen peptides and milk until smooth.
Pour the mixture into the baking dish.

5️⃣ Season & Top

Add garlic powder, mixed herbs, salt, pepper and chilli flakes.
Stir gently to distribute everything evenly.
Sprinkle shredded cheese over the top (add extra if you like).

6️⃣ Bake

Bake for 40–50 minutes, or until the frittata is fully set and golden on top.

A simple way to check: gently shake the dish — once cooked, the centre should no longer jiggle.

Baking time may vary depending on the size and depth of your baking dish (approximately 20 × 20 cm works well).

7️⃣ Rest & Serve

Allow the frittata to rest for a few minutes before slicing. Serve warm or store for later.

Meal Prep Tip

If preparing this recipe ahead of time:

  1. Allow the frittata to cool completely on a rack.

  2. Remove the baking paper.

  3. Slice into portions before refrigerating.

This helps prevent moisture building up underneath and keeps the base from becoming soggy.
