A Slimming-Friendly Classic — Reinvented

This isn’t your usual pastry-heavy quiche. It’s lighter, easier, and honestly more versatile. I made it on a whim this week and… yep, making it again already. Even my husband (who’s usually suspicious of “healthy” recipes) asked for more.

It’s the ideal solution for busy days: make it in the morning, serve it up with a green salad at lunch, and have leftovers sorted for tomorrow.

Second time this week, and we’re not even close to tired of it.

Step-by-Step Cooking Guide

Step 1: Prep the Dish

  • Preheat oven to 180°C fan
  • Lightly grease a 20–23cm quiche dish with low-cal spray
  • Optional: line with parchment for easy lift-out

Step 2: Whisk the Eggs

  • In a large bowl, whisk together eggs and fat-free cottage cheese or quark
  • Season with salt, pepper, and your favorite herbs (mixed herbs or paprika work great)
  • Tip: Blend the mixture if you prefer a smoother texture

Step 3: Sauté the Veg & Protein

  • Lightly cook onions and spinach in a pan with spray oil until softened
  • Mix with chopped cooked protein (lean ham, bacon medallions, or veggie sausages)

Step 4: Assemble

  • Stir veggie/protein mix into the egg mixture
  • Pour into prepared dish
  • Top with halved cherry tomatoes and a sprinkle of reduced-fat cheese

Step 5: Bake

  • Bake for 35–40 minutes, or until golden on top and set in the middle
  • Let cool for 5–10 minutes before slicing

Ingredient Tips & Substitutions

Ingredient Insights

  • Eggs: The foundation of the quiche – use large for fluffier texture

  • Tomatoes & Spinach: Add freshness and color

Substitution Suggestions

Ingredient Substitute
Cottage Cheese Quark or fat-free Greek yogurt
Bacon Medallions Lean cooked sausage, veggie mince
Spinach Kale, rocket, or skip entirely
Cherry Tomatoes Sliced peppers or sun-dried tomatoes
