Zucchini Risotto Ingredients
Find the full list and quantities in the recipe card below.
Fresh Zucchini - I used 2 medium sized green zucchini in this recipe, but you can use any color zucchini.
Rice - You can use any variety of risotto rice in this dish. I like to use arborio rice, but carnaroli or vialone nano rice works in this dish too.
Stock - I've used vegetable stock, however if you aren't serving vegetarian diners then chicken stock would work well here too.
Wine - use a good quality white wine in this recipe, something you would be happy to drink a glass of yourself as it will make a difference to the flavor of the finished risotto. However, if you prefer a no-alcohol risotto you can leave out the wine and just stick with the lemon juice for acidity.
How to Make Easy Zucchini Risotto - Step-By-Step

Sauté the finely chopped onion in butter in a large dutch oven or a large pot until it starts to soften. Add the chopped zucchini and sauté until it also softens, a further 5 minutes.
Meanwhile heat the broth to boiling point in a separate saucepan and then turn on to a low heat. Keeping the broth warm throughout the cooking process will help the risotto cook evenly.
Stir the minced garlic into the onion and zucchini mix for a minute, ensuring it doesn't burn then stir in the risotto rice and cook for 1-2 minutes until the rice becomes slightly translucent at the edges.
Add the white wine if using. Stir until the rice grains absorb the liquid then start adding the warm broth, one ladleful at a time. Allow the rice to absorb the liquid before adding more.
Stir the risotto frequently to prevent it from sticking to the bottom of the pan. Continue adding the warm broth and stirring for about 18-20 minutes or until the rice reaches a creamy and tender consistency. The final result should have a slight bite to it (al dente).
Once the rice is cooked, remove from the heat and stir in the lemon zest, lemon juice and the grated Parmesan cheese. Season with salt and black pepper to taste and serve with extra Parmesan if desired.
Variations & Substitutions for Courgette Risotto
You can easily transform this dish into a vegan option by swapping the butter for extra virgin olive oil and using a vegan Parmesan cheese alternative at the end, or just leaving the cheese out altogether. If you choose to add the white wine, just make sure to check the label to ensure it is vegan friendly.
While I prefer having distinct pieces of zucchini in my risotto, you can also grate the zucchini on a large box grater if you want a much softer texture that melts completely into the rice.
Add some leafy greens like spinach or kale towards the end of cooking and allow to wilt.
While this recipe is optimized for zucchini, you can absolutely use yellow summer squash or pattypan squash since they all cook down beautifully into the rice base.
This recipe would work equally well with asparagus in place of the zucchini.
If you run out of Parmesan, fresh Pecorino Romano makes an excellent substitute that adds a slightly saltier, tangier bite to the dish, though you should taste it before adding extra salt at the end.
Fresh basil, finely chopped chives, or a hint of fresh thyme all pair beautifully with the lemon and zucchini if you want to change up the fresh herbs.
To transform this simple dish into a hearty main event, you can stir in grilled chicken, pan seared garlic shrimp, or even crumbled pancetta right at the very end.
Tips & Tricks
Seasoning is absolutely key to unlocking the flavor of the rice, so taste your pan frequently and ensure you add enough salt throughout the cooking process.
Don't rush the process - the rice needs enough time to absorb the liquid.
Equally, don't overcook the rice, you want it to be al-dente with a little bite.
Use a gentle hand as you work, since over-stirring too aggressively can damage the grains and make the final dish mushy rather than creamy.
Tips for making creamy risotto
- Unlike other rice - do not rinse risotto rice before you start cooking or you will remove the starch from the rice that you need to give risotto its delicious creamy texture.
- Use a good quality risotto rice, don't be tempted to use regular long grain rice as it will not result in the same creamy texture.
- Always use a hot stock, keep it in a saucepan over medium low heat and ladle into the risotto as you cook.
- Gentle and consistent stirring is the secret to success because agitating the grains against one another is exactly what coaxes the starches out of the rice and into the broth.
How To Serve
I like to keep things simple and add some crusty bread or garlic bread to the dinner table. A summer salad is a great accomaniment - this Arugula and Burrata Salad is a favorite, as is this simple Beet and Cucumber Salad.
Fresh greens also work nicely here, try lightly sauteed spinach, my Easy Charred Broccolini or my Easy Buttered Kale.
Storing and Reheating
Once cooled, store in an airtight container in the refrigerator for 3-4 days. When ready to reheat, place into a skillet and warm up gently on the stove. You may want to loosen the risotto with a little extra vegetable stock or water.
Can you freeze this Risotto?
Once cooked and cooled, place the risotto into an airtight container and store in the freezer for up to 3 months.
When ready to enjoy; defrost overnight in the refrigerator before heating up gently on the stove until piping hot. Just be aware that the texture of the risotto can change during the freezing and defrosting processes, though it should still taste great.
Frequently Asked Questions
Can you use regular rice to make risotto?
Yes, you can, but I don't recommend it. Risotto requires a specific type of rice like arborio, carnaroli rice or vialone nano. They have the perfect starch content which is required to create the creamy texture we all expect from a good risotto. Regular long grain rice or short-grain rice isn't so starchy and won't give you the same creamy results.
Can you reheat risotto?
Risotto is a dish that is best enjoyed straight away, while the rice still has some bite. Whilst you can reheat it, and it will still taste good, the texture is different as the rice will have absorbed more liquid and will be softer and have lost its bite.
Do you really have to stir risotto the whole time you are cooking it?
Yes, to make the best risotto you need to stir it while it cooks. Frequent stirring not only helps all the ingredients to incorporate, but by stirring the rice you activate all the starches in the rice. This gives you that lovely creamy texture we all associate from a good risotto.
Do you have to use warm broth for risotto?
Yes, always keep your broth simmering in a separate pan on the stove. Adding cold or room-temperature liquid lowers the temperature of the cooking pan, which slows down the cooking process and prevents the rice from releasing its starches evenly.
How do you know when risotto is finished cooking?
Look for the wave effect, known in Italy as all'onda. When you draw a wooden spoon through the center of the pan, the risotto should slowly flow back to fill the gap. The rice should be tender but still retain a firm, distinct bite in the center of each grain.
Can you make risotto ahead of time for a dinner party?
Yes, you can par cook the risotto earlier in the day by taking it through about half of its cooking time until the rice is still quite firm. Spread it out flat on a baking sheet to cool rapidly and stop the cooking process, then cover and keep it at room temperature for up to a few hours. When your guests arrive, simply bring your remaining stock back to a simmer, add the rice back to the pan, and finish the last ten minutes of cooking and stirring as normal.
Why did my risotto turn out sticky or gummy instead of creamy?
Sticky risotto usually happens if the heat on your stove was turned up too high, causing the liquid to evaporate faster than the rice could actually absorb it and cook through. It can also happen if you used the wrong type of rice or stirred too aggressively with a heavy hand, which breaks the delicate grains and releases a dense, gluey paste rather than a smooth, velvety sauce.
Can you make risotto without wine?
You can absolutely skip the wine if you prefer not to cook with alcohol or simply do not have an open bottle on hand. To mirror that essential brightness and acidity that cuts through the rich starch, simply substitute the wine with an equal amount of chicken or vegetable broth mixed with a generous squeeze of fresh lemon juice just before you start ladling in the hot stock.
Do you need to add heavy cream to make risotto creamy?
Authentic Italian risotto never contains heavy cream or milk because the signature velvety texture comes entirely from the starch released by the rice grains themselves as they cook. Finishing the dish with just a pat of butter and a handful of finely grated Parmesan cheese at the very end is all you need to create a luxurious, glossy sauce.

I just tried this recipe and my family absolutely loved it!! Definitely a new favorite, and very happy to have it in the rotation. I shaved the zucchini with a vegetable peeler because I thought it would be an easier sell for my picky eater (it worked!). And I actually loved the texture that way. I also skipped the wine. Next time I would double the recipe for my family of five because they couldn't get enough!
