Why you’ll love this Caramelized Fennel One Pot Orzo Pasta
This is one of those recipes where everything happens in the one pot so there is no extra boiling, draining or dishes. The orzo cooks right in the sauce, soaking up all that caramelized fennel, garlic and butter and creates the most creamy, glossy finish without needing loads of cream (that can be an optional ingredient).
If you love my one pot orzo with cherry tomatoes or even my leek risotto, this is very much that same style of cooking. Simple, comforting and perfect for an impressive yet simple midweek dinner.
Ingredients for caramelized Fennel Orzo
The caramelized fennel is the star of the show in this recipe!
- Fennel: Make sure you slice the fennel nice and thin so it can properly caramelize and turn soft, sweet and jammy. You can use a mandolin or sharp knife for this step. And don’t throw away the fronds! They are stirred through at the end and also used as a garnish.
- Butter: I like to use butter to help the fennel caramelize and to add a bit of richness to the sauce. You can leave this out and use only olive oil if you prefer.
- Orzo: Orzo is a small, rice-shaped pasta that cooks directly in the sauce, almost like a risotto. If you don’t have orzo, you can use any other small pasta shape such as ditalini or even stelline.
- Lemon zest and juice: The zest and juice are really important here. They cut through the richness and lift the whole dish, so don’t skip it.
- Chicken broth or stock: You can replace this with vegetable stock to make this dish vegetarian!
How To Make caramelized Fennel Orzo
Start by slowly caramelizing the fennel in butter and olive oil until it’s soft, golden and slightly jammy. From there, everything cooks in the same pot!
Step 1: In a large fry pan on a medium heat, add 4tbsp of butter and the olive oil. Once the butter has melted and is foaming, add the fennel to the pan. Lower the heat to low – medium and cook for 20 minutes, stirring occasionally, or until the fennel is soft and jammy.
Step 2:
Increase the heat to medium-high, add the garlic and lemon zest and cook for 2 minutes. Stir through the orzo and cook for 1 minute until lightly toasted, then add the stock, season and bring to a boil. Reduce to a gentle simmer and cook for 5–8 minutes, stirring regularly, until the orzo is plump, al dente and most of the liquid has been absorbed. Add the cream, lemon juice, remaining butter and parmesan cheese and stir through.
Step 3: Take the orzo off the heat and stir through the basil and fennel fronds.
FAQ’s
Just like when you caramelize onions, slice it thin and cook it slowly over a medium to low heat in butter and olive oil. Don’t rush this step. Give it time to soften and turn golden and jammy, as this is where all the flavour comes from.
Yes, you can use another small pasta shape like stelline, ditalini or even small shells. Just keep in mind the texture may be slightly different, as orzo gives that really creamy, risotto-like finish.
I highly recommend it. The zest adds a fresh, fragrant flavour while the juice balances the richness of the dish.
This works beautifully with grilled chicken, prawns or even some crispy pancetta stirred through at the end.
You can, but I prefer chicken stock for a deeper, richer flavour. If you are keeping it vegetarian, just make sure you are using a really good quality vegetable stock.
How To Store
- Fridge: Store leftovers in an airtight container in the fridge for up to 3 days.
- Texture: The orzo will continue to absorb liquid and thicken as it sits, this is completely normal.
- Reheating: Reheat gently on the stove or in the microwave with a splash of chicken stock or water to loosen it.
- To finish: Add a little extra lemon juice, some fresh herbs and a big drizzle of olive oil before serving to bring it back to life.
