Instructions
Bring a large pot of salted water to a boil. Cook the gluten-free pasta according to package directions until al dente.
Before draining, reserve 1/2 cup of the pasta cooking water.
While the pasta cooks, place the diced bacon in a large skillet over medium heat. Cook until crispy, about 6–8 minutes.
Add the minced garlic during the last minute of cooking, if using.
In a medium bowl, whisk together the eggs, Parmesan cheese, salt, and black pepper until well combined.
Drain the pasta and immediately add it to the skillet with the bacon. Toss to coat in the rendered bacon fat.
Remove the skillet from the heat. Slowly pour in the egg and cheese mixture while continuously tossing the pasta.
Add reserved pasta water, a few tablespoons at a time, until the sauce becomes smooth, glossy, and coats the pasta.
Taste and adjust seasoning as needed.
Garnish with additional Parmesan cheese, fresh parsley, and extra black pepper before serving.
