Ingredients Notes
To make this recipe you will need the following ingredients:
- Fennel Bulbs: Fennel has a mild aniseed flavour when raw, but roasting transforms it into something much sweeter and more mellow. Thinly slicing the fennel helps it cook evenly and allows the edges to caramelize beautifully.
- Lemon Juice: Fresh lemon juice adds brightness and balances the natural sweetness that develops as the fennel roasts.
- Garlic: Fresh garlic adds plenty of flavour and works perfectly with the lemon and fennel. As it roasts, it becomes milder and slightly sweet.
- Olive Oil: Helps the fennel roast evenly and caramelize while carrying the flavours of the garlic and lemon.
- Salt and Black Pepper: Simple seasoning is all that is needed to enhance the natural flavour of the fennel and balance the sweetness.
- Fresh Italian Parsley: Added at the end for freshness, colour and a light herby flavour that complements the roasted fennel perfectly.
Once you've gathered all the ingredients and prepared them accordingly, you're all set to create this easy and delightful recipe.

Variations and Substitutes
There are plenty of ways to adapt this Lemon Garlic Roasted Fennel depending on what you have on hand, whether you want to add extra vegetables or vary the flavours.
- Extra Vegetables: Fennel roasts beautifully alongside onions, bell peppers, courgette/zucchini, carrots or cherry tomatoes. These all complement the sweet, mellow flavour of the fennel.
- Vary the Citrus: Lemon adds a lovely freshness, but orange works particularly well with fennel and enhances its natural sweetness. You can also use a combination of both.
- Herbs: Fresh Italian parsley adds freshness, but dill, thyme, oregano or basil are all delicious alternatives.
- Garlic: Fresh garlic gives the best flavour, but garlic powder can be used if needed. You can also increase the garlic if you are a garlic lover.
- Add Cheese: A sprinkling of freshly grated parmesan or crumbled feta over the roasted fennel adds a delicious savoury element.
- Add Some Crunch: Toasted pine nuts, sliced almonds or walnuts make a great finishing touch and add extra texture.
How to Slice a Fennel Bulb
Trim off the stalks and any fronds from the fennel bulb, reserving some of the fronds for garnish if desired. Cut a thin slice from the base, then cut the bulb in half from top to bottom.
Lay each half cut-side down on a chopping board and slice from top to bottom into strips. If the core looks particularly thick or tough, you can remove it before slicing, although smaller, tender cores can be left in place.
Serving Suggestions
This Lemon Garlic Roasted Fennel makes a delicious side dish for a variety of meals and is a great way to add something a little different to your plate.
It pairs particularly well with grilled or roasted chicken, pork chops, steak and sausages. It is also excellent alongside fish and seafood, especially salmon, cod, haddock, sea bass or prawns/shrimp.
For a vegetarian meal, serve it with quinoa, couscous, pasta or a simple grain bowl. It also works beautifully as part of a roasted vegetable platter with other Mediterranean-style vegetables.
A little shaved parmesan or crumbled feta sprinkled over the top before serving is also a delicious way to finish the dish.
