Fried Leeks: How to Make This Easy, Savoury Side Dish or Crispy Topping
Introduction
Leeks are one of the UK’s most underrated vegetables — mild, sweet, and deeply flavourful when cooked right. While most people use them in soups or stews, fried leeks are a game-changing way to enjoy this allium.
Whether you want crispy leek shreds to top a dish or soft, caramelised leeks as a side, frying leeks brings out their best qualities — richness, sweetness, and versatility.
In this guide, we’ll show you how to make three types of fried leeks: soft sautéed, golden crispy, and caramelised. You’ll also learn how to clean, prep, and season them properly, what dishes to serve them with, and how to store leftovers.
Why Fry Leeks?
Frying leeks intensifies their flavour and creates:
✅ A sweet, savoury profile
✅ A golden, crispy texture or soft caramelised melt
✅ A beautiful garnish or main component
✅ A great way to use up odds and ends from the garden
They’re simple to cook, quick to prepare, and incredibly versatile in the kitchen.
Fried Leeks Recipe (Soft & Savoury Version)
🧄 Ingredients (Serves 2–4 as a side)
- 2 large leeks
- 2 tbsp olive oil or butter (or mix of both)
- Salt and black pepper to taste
- Optional: garlic, thyme, lemon zest, or grated parmesan
👩🍳 Method
1. Clean the leeks thoroughly
- Trim off the root and dark green top
- Slice in half lengthwise
- Rinse under running water, fanning out layers to remove any grit
- Slice into thin half-moons or rings
2. Heat your pan
- Use a non-stick or cast iron pan over medium heat
- Add oil, butter, or a mix
3. Add leeks and sauté
- Toss in sliced leeks
- Season lightly with salt and pepper
- Stir occasionally and cook for 10–12 minutes until soft and golden at the edges
4. Optional extras
- Add garlic in the last 2 minutes
- Finish with lemon zest or grated cheese
- Sprinkle over herbs before serving
Serve hot as a side dish, pasta mix-in, or toast topping.
Crispy Fried Leeks (Garnish or Snack)
🧄 Ingredients
- 1 large leek
- 100ml neutral oil (e.g. sunflower, vegetable)

👨🍳 Method
1. Prep the leeks
- Slice only the white and pale green part into very thin julienne strips
- Rinse and dry thoroughly with a tea towel or salad spinner
2. Heat the oil
