Step‑by‑Step Instructions for 20-Minute Chicken Alfredo
Step 1: Boil the Pasta
Bring a large pot of salted water to a rolling boil over high heat. Once boiling, add in your gluten-free fettuccine, stirring occasionally to prevent sticking. Cook according to package directions, usually about 8-10 minutes, until al dente. Restrain from overcooking, as you want it to maintain a nice bite. Reserve 1/3 cup of pasta water before draining the pasta, then set aside.
Step 2: Prepare the Alfredo Sauce
While your pasta cooks, blend together the ingredients for the dairy-free alfredo sauce in your blender. In about 2-3 minutes, you should achieve a creamy consistency. Make sure to taste and adjust the flavors to your liking, perhaps adding a splash more lemon juice for brightness. Set this delightful goodness aside but keep the blender handy for a later step.
Step 3: Cook the Chicken
In a large skillet, pour in some olive oil or plant-based butter over medium-high heat. Once hot and shimmering, carefully add the bite-sized pieces of boneless skinless chicken breasts, seasoning them generously with sea salt. Cook for about 7-10 minutes, stirring occasionally until browned and cooked through, ensuring the internal temperature reaches 165°F. Once done, transfer the chicken to a plate, allowing it to rest while you sauté the veggies.
Step 4: Sauté the Vegetables
Using the same skillet, add a touch more olive oil if needed, and toss in the sliced leeks and broccoli. Sauté them over medium heat for about 3 minutes until they turn vibrant green and tender but still crisp. You can mix in a pinch of salt to bring out their flavors as they sauté. To deglaze, pour a splash of white wine or chicken stock into the skillet, cooking for an additional 2 minutes until the liquid reduces slightly and the vegetables are tender.
Step 5: Combine Everything
Once the vegetables are ready, reduce the heat to low and return the cooked chicken to the skillet. Then, take the drained pasta and add it to the mixture. Pour in the blended dairy-free alfredo sauce, stirring gently to combine everything evenly. If the sauce looks too thick, gradually add reserved pasta water until you reach your desired creamy consistency, where each strand of pasta is lovingly coated.
Step 6: Garnish and Serve
Finally, remove the skillet from heat and garnish your beautiful 20-Minute Chicken Alfredo with freshly chopped parsley or chives for a burst of color. Serve immediately to enjoy the warm, creamy dish at its best, complete with the zest of lemon and a medley of flavors that will please everyone at the table.

Make Ahead Options
These 20-Minute Chicken Alfredo can easily be prepped ahead, making your weeknight dinners a breeze! Start by soaking the sunflower seeds for the dairy-free alfredo sauce up to 24 hours in advance, ensuring optimal creaminess. You can also chop the leeks and broccoli and store them in an airtight container in the refrigerator for up to 3 days. When you’re ready to enjoy this delightful dish, simply cook the chicken and other ingredients, then combine everything as outlined in the recipe. For the best quality, prepare the sauce fresh before serving to keep it creamy and delicious—your family will appreciate the time you saved!
