Set two pans on your stove, a 4 qt saucepan for broth, a larger pot for the risotto. I use a wide 6 qt stock pot like pan, a dutch oven would work as well.
Fill the saucepan with broth and keep warm over medium-low heat. You don’t want this to boil.
In the larger pot or pan heat over medium-high heat then add two tablespoons of the oil and one tablespoon of the butter.
Add in the diced onion and leeks. Sauté for 5-6 minutes or until starting to caramelize.
Add in the salt and pepper, stir, then add in the rice and stir for one minute. Add in the wine, let sit for a few seconds then stir until it is completely absorbed.
Add in the zest, juice salt and pepper. Stir again.
Add in one and a half cups of the warm broth to the rice, Let sit for one minute then stir. Stir occasionally until it is completely absorbed. Repeat with only a half a cup of broth, let sit for a minute, then stir until combined until the rice is tender but still firm aka “al dente”. This will take about 30 minutes. You may or may not use all of the broth, depends on how high of heat you use, if you use a little more than 2 cups of rice, or if you are in a dryer environment. And if you like the rice a little more softer to the bite, add more broth.
Once the texture is to your liking, remove the risotto from the heat and stir in one cup of the parmesan cheese, the shredded gouda and the remaining tablespoon of butter. Taste and add more salt and pepper or lemon juice if desired. Keep warm until ready to serve.
Serve with a sprinkling of the remaining parmesan cheese, a little of the remaining olive oil and chopped Italian parsley.
