Thoroughly wash the 2 large zucchini and trim off the ends. Using a spiralizer, create zucchini noodles. If you don't have a spiralizer, just run a vegetable peeler down the length of the zucchini to make thin ribbons.
Next, cut the 1.5 pounds chicken breast into bite-sized pieces. Chop the 1 shallot and mince the 4-5 cloves garlic; set aside.
Combine 1/3 cup gluten-free flour, 1 teaspoon Italian seasoning, 1 1/2 teaspoons kosher salt, and 1/2 teaspoon ground black pepper in a shallow bowl. Transfer the flour mixture to a large resealable plastic bag.
Add the chicken pieces to the flour, seal the bag, and shake well to coat evenly. Now, heat a large skillet over medium heat. Add 1 tablespoon of the 3 tablespoons olive oil and heat until shimmering.
Add coated chicken and cook for 5-6 minutes, or until nicely golden brown. Once done, remove the chicken pieces onto a plate and cover to keep them warm.
Add remaining oil to the skillet and heat until hot. Add the shallot and garlic, and sauté for 1-2 minutes, until the garlic is fragrant and the shallots begin to soften.
Pour in the1 cup chicken broth, 1 large lemon, and lemon zest. Cook on low, scraping any browned bits from the bottom of the skillet. Stir in the chicken bites, and simmer the sauce for about 3-4 minutes.
Stir in the ½ cup parmesan cheese, mix well until the sauce is thickened and coats the chicken bites. Immediately add the zucchini noodles.
Cook for about 2 minutes, tossing with tongs until the zoodles are slightly softened. Transfer the zoodles to a serving dish.
Garnish with chopped one small bunch fresh parsley and sprinkle with r¼ tsp red chili flakes. Serve immediately and enjoy!
Notes
Cut chicken into equal pieces for even cooking.
If you're not a fan of chicken, you can switch it out for shrimp scampi with zoodles.
Zoodles can be prepped in advance by keeping the spirals in the fridge until ready to cook.
While the chicken and sauce can be reheated easily, zoodles are best enjoyed fresh.
You may also use vegetable broth instead of chicken broth.
Use fresh garlic if possible. If you don't have any fresh garlic, you can substitute one tablespoon of garlic powder.
