Ingredients You’ll Need for Dairy Free Chicken Alfredo with Cauliflower Sauce

Essentials

• 1 teaspoon olive oil (for the sauce)
• ½ yellow onion, chopped
• 3 cloves garlic, crushed (or finely minced)
• 3 cups chopped cauliflower (about 12 ounces)
• 1 cup chicken stock (use low-sodium if preferred)
• 1–2 tablespoons nutritional yeast (adds savory, cheesy flavor)
• ½ tablespoon freshly squeezed lemon juice
• 1–2 teaspoons sea salt (to taste)
• ½ teaspoon soy sauce (or tamari for gluten-free)
• 12 ounces uncooked pasta (I like fettuccine or linguini)
• 4 teaspoons olive oil, divided (for tossing pasta and cooking chicken)
• 3 ounces baby spinach
• 2 chicken breasts, cut into bite-sized pieces
• ½ teaspoon sea salt and ½ teaspoon black pepper (to season chicken)

Optional add-ons

• Red pepper flakes for a gentle heat
• Fresh parsley or basil, chopped, for garnish
• Grated vegan Parmesan or extra nutritional yeast for topping
• Sautéed mushrooms or roasted cherry tomatoes for extra veggies
• A little garlic powder or onion powder for extra flavor in the sauce

Substitutions and shortcuts

• Cauliflower: Use frozen cauliflower florets if fresh isn’t on hand. Thaw slightly or add a minute onto the simmer time.
• Chicken stock: Vegetable stock works fine for a pescatarian or vegetarian swap (then skip the chicken or substitute with chickpeas or tofu).
• Nutritional yeast: If you don’t have it, increase the lemon a touch and add a pinch of salt; the sauce will still be tasty but less “cheesy.”
• Pasta: Use gluten-free pasta if needed; adjust cook time according to package directions.
• Chicken: Swap for pre-cooked rotisserie chicken to save time — just shred and add at the end.
• Blender: If you don’t have a high-speed blender, blend in batches and strain if you want an extra-smooth finish.
• Quick sauce: Use a food processor for a chunkier, rustic sauce, or toss cauliflower into a pressure cooker for 3 minutes to speed things up.

How to Make Dairy Free Chicken Alfredo with Cauliflower Sauce Step-by-Step

I like to work in small stages so dinner feels easy, not frantic. Here’s how I do it, with tips for every step.

1. Prep your ingredients first

   • Chop the onion and cauliflower and crush or mince the garlic. Cut the chicken into bite-sized pieces and season it with the ½ teaspoon sea salt and ½ teaspoon pepper. Measure out your chicken stock and nutritional yeast. Having everything ready makes cooking calm and steady.

2. Make the cauliflower alfredo base

   • Heat 1 teaspoon of olive oil in a medium-sized pot over medium heat.
   • Add the chopped onion and crushed garlic. Sauté for about 3 minutes, stirring occasionally, until the onion becomes soft and slightly translucent. This step builds flavor; don’t rush it.
   • Add the chopped cauliflower and pour in 1 cup of chicken stock. Increase the heat until the pot comes to a gentle boil.
   • Cover the pot, reduce the heat to a simmer, and cook for about 5 minutes — you want the cauliflower fork-tender, not mushy.
   • Turn off the heat and let the mixture cool slightly so it’s safe to handle. Then transfer everything from the pot into your blender.

3. Blend the sauce until silky

   • To the blender add 1–2 tablespoons nutritional yeast (start with 1 tablespoon and add more to taste), ½ tablespoon freshly squeezed lemon juice, 1–2 teaspoons sea salt (start smaller and taste later), and ½ teaspoon soy sauce.
   • Blend on high until the sauce is very smooth and creamy. If it’s too thick, add a splash of water or more chicken stock, a tablespoon at a time, until you reach a pourable but creamy consistency.
   • Taste the sauce and adjust seasoning: add more salt, nutritional yeast, or lemon if you’d like it brighter. Set the sauce aside.

4. Cook the pasta

   • Bring a large pot of salted water to a rolling boil. Add 12 ounces of your pasta and cook according to the package directions until al dente. Cooking to al dente helps the pasta hold up when tossed with the sauce.
   • Drain the pasta through a colander and return it to the pot. Drizzle 2 teaspoons of olive oil over the cooked pasta and toss so each strand is lightly coated — this prevents sticking and helps the sauce cling.
   • Add the 3 ounces of baby spinach to the pasta while it’s still warm so it wilts gently into the noodles.

5. Cook the chicken

   • While the pasta water is heating (so multitask and save time), season the chicken pieces with the remaining ½ teaspoon sea salt and ½ teaspoon pepper.
   • Heat the remaining 2 teaspoons of olive oil in a medium-sized frying pan over medium-high heat.
   • Add the chicken in a single layer and let it cook without moving for a couple of minutes so it gets a nice golden color. Flip and cook until browned on the other side and cooked through — total time depends on piece size but often 6–8 minutes.
   • If you’re using pre-cooked chicken, warm it gently in the pan with a splash of stock or a drizzle of oil.

6. Bring it all together

   • Add the cooked chicken to the pot with the pasta and wilted spinach.
   • Pour the cauliflower alfredo sauce over the pasta and chicken. Toss everything gently until well coated; if the sauce feels too thick, loosen with a little reserved pasta water or extra stock to reach your desired texture.
   • Give it a final taste and add extra salt, pepper, or nutritional yeast if you want more depth. Serve immediately while warm.

Tips I use every time:

• If your blender has a hot liquid warning, let the cauliflower cool a minute and blend in short pulses, venting the lid slightly.
• Reserve a cup of pasta water before draining — that starchy water is great for thinning sauces and helping them cling to noodles.
• If you prefer a thinner sauce for tossing, add 2–3 tablespoons of pasta water right at the end and mix.

Common Mistakes to Avoid

Even simple recipes have a few common trip-ups. Start here so your dinner feels like a success.

Mistake 1: Overcooking the cauliflower

Overcooked cauliflower can turn watery and lose flavor. Cook until just fork-tender (about 5 minutes after boiling) so the blender transforms it into a silky sauce rather than a soupy mash.

Mistake 2: Skipping seasoning tweaks

Cauliflower is mild, so taste as you go. Add salt, nutritional yeast, and lemon incrementally. It’s easy to under-season at first and end up with a bland sauce.

Mistake 3: Crowding the chicken pan

If you toss all the chicken into a hot pan at once, it steams instead of browns. Cook in a single layer and give pieces room to sear for that golden, flavorful crust.

Serving Suggestions for Dairy Free Chicken Alfredo with Cauliflower Sauce

This dish is cozy and versatile. A few simple sides or garnishes can make it feel special without extra work.

Light salad

A crisp green salad with a lemon vinaigrette balances the creamy pasta. Use peppery arugula or mixed baby greens, sliced cucumber, and a few shaved carrots for color.

Garlic-roasted vegetables

Roast broccoli, asparagus, or Brussels sprouts with olive oil and a pinch of salt at 425°F (220°C) for 12–15 minutes. The roasted veg adds texture and keeps the meal veggie-forward.

Bread or garlic toast

A warm slice of crusty bread or dairy-free garlic toast is comforting for sopping up any leftover sauce. Brush with olive oil, toast under the broiler, and finish with chopped parsley and a pinch of salt.
