Ingredients Method

Ingredients

  

• 8 ounces whole-wheat fettuccine or your favorite pasta (regular or gluten-free)
• 1 pound boneless, skinless chicken breasts, thinly sliced or pounded to even thickness
• 1 medium head cauliflower, cut into florets (about 5–6 cups)
• 1 1/2 cups low-sodium chicken broth (plus extra as needed to thin the sauce)
• 3–4 cloves garlic, minced
• 1/2 cup freshly grated Parmesan cheese
• 2 tablespoons olive oil, divided
• 2 tablespoons unsalted butter (optional for extra richness)
• 1/2 teaspoon onion powder
• 1/4 teaspoon red pepper flakes (optional)
• Zest of 1/2 lemon and 1–2 teaspoons fresh lemon juice
• Salt and black pepper to taste
• Fresh parsley, chopped, for garnish

Method

 

1. Cook the pasta. Bring a large pot of salted water to a boil. Cook the pasta until al dente according to package directions. Reserve 1 cup of pasta water, then drain.
2. Simmer the cauliflower. Add cauliflower florets to a pot with the chicken broth. If needed, add water to barely cover. Bring to a simmer, cover, and cook until very tender, about 10–12 minutes.
3. Sauté the garlic. While the cauliflower cooks, heat 1 tablespoon olive oil in a large skillet over medium heat. Add garlic and cook for 30–60 seconds until fragrant. Do not brown. Transfer the garlic to your blender or food processor.
4. Blend the sauce. Using a slotted spoon, transfer the tender cauliflower to the blender with the garlic. Add about 1 cup of the hot cooking liquid. Add Parmesan, onion powder, a pinch of salt, and pepper. Blend until very smooth and creamy. Add more broth or a splash of pasta water to reach your desired thickness. Taste and adjust seasoning with salt, pepper, and lemon juice.
5. Cook the chicken. Pat the chicken dry and season both sides with salt and pepper. In the same skillet, heat the remaining 1 tablespoon olive oil over medium-high. Sear chicken 3–4 minutes per side until golden and cooked through. Remove to a plate and slice.
6. Finish the sauce in the skillet. Lower the heat to medium-low. If using butter, add it to the skillet and let it melt. Pour in the cauliflower sauce and stir, scraping up any browned bits from the pan. Add lemon zest and red pepper flakes if using. Warm gently; avoid boiling.
7. Toss with pasta. Add cooked pasta to the skillet and toss until coated. Use reserved pasta water to loosen if needed. Fold in the sliced chicken.
8. Serve. Top with extra Parmesan, a sprinkle of parsley, and freshly ground black pepper. Taste once more and add a squeeze of lemon if you want extra brightness.

• Smart swaps keep calories in check, but you still get that classic Alfredo comfort.
• Everything cooks in under 45 minutes, with simple steps and common pantry ingredients.

Step-by-Step Instructions

1. Cook the pasta. Bring a large pot of salted water to a boil.

   Cook the pasta until al dente according to package directions. Reserve 1 cup of pasta water, then drain.

2. Simmer the cauliflower. Add cauliflower florets to a pot with the chicken broth. If needed, add water to barely cover.

   Bring to a simmer, cover, and cook until very tender, about 10–12 minutes.

3. Sauté the garlic. While the cauliflower cooks, heat 1 tablespoon olive oil in a large skillet over medium heat. Add garlic and cook for 30–60 seconds until fragrant. Do not brown.

   Transfer the garlic to your blender or food processor.

4. Blend the sauce. Using a slotted spoon, transfer the tender cauliflower to the blender with the garlic. Add about 1 cup of the hot cooking liquid. Add Parmesan, onion powder, a pinch of salt, and pepper.

   Blend until very smooth and creamy. Add more broth or a splash of pasta water to reach your desired thickness. Taste and adjust seasoning with salt, pepper, and lemon juice.

5. Cook the chicken. Pat the chicken dry and season both sides with salt and pepper.

   In the same skillet, heat the remaining 1 tablespoon olive oil over medium-high. Sear chicken 3–4 minutes per side until golden and cooked through. Remove to a plate and slice.

   If using butter, add it to the skillet and let it melt. Pour in the cauliflower sauce and stir, scraping up any browned bits from the pan. Add lemon zest and red pepper flakes if using.

   Warm gently; avoid boiling.

7. Toss with pasta. Add cooked pasta to the skillet and toss until coated. Use reserved pasta water to loosen if needed. Fold in the sliced chicken.

How to Store

• Refrigerator: Store leftovers in an airtight container for up to 3 days. The sauce will thicken as it chills.
• Reheat: Warm gently on the stove over low heat with a splash of broth or water to loosen. Stir often.

  Avoid high heat to prevent the sauce from tightening.

• Freezer: The blended cauliflower sauce freezes better on its own than with pasta. Freeze in portions for up to 2 months. Thaw overnight and whisk while reheating.

Benefits of This Recipe

• Lighter than classic Alfredo: Cauliflower replaces heavy cream, cutting calories and saturated fat while keeping the creamy feel.
• High in protein: Chicken and Parmesan make the dish satisfying and supportive of active days.
• Fiber boost: Whole-wheat pasta and cauliflower add fiber, which helps with fullness and digestion.
• Budget-friendly: Cauliflower and pantry staples keep costs down without sacrificing flavor.
• Kid- and crowd-friendly: It tastes like comfort food, so it’s an easy sell at the table.

Common Mistakes to Avoid

• Undercooking the cauliflower: If it’s not fully tender, the sauce can turn grainy.

  Cook until fork-soft.

• Skipping enough seasoning: Cauliflower is mild. Be generous with salt, pepper, garlic, and lemon to bring it to life.
• Boiling the finished sauce: High heat can make the sauce separate. Keep it at a gentle simmer or lower.
• Overcooking the chicken: Thin, even pieces cook quickly.

  Pull them off the heat as soon as they’re done to keep them juicy.

• Forgetting pasta water: Starchy water helps the sauce cling and stay silky. Save a cup before draining.

Recipe Variations

• Broccoli or spinach: Stir in steamed broccoli florets or a few handfuls of baby spinach at the end for extra greens.
• Mushroom Alfredo: Sauté sliced mushrooms with the garlic and blend some into the sauce, or fold them in at the end for texture.
• Dairy-light version: Reduce Parmesan to 1/4 cup and add 1–2 tablespoons nutritional yeast for a savory note.
• Gluten-free: Use gluten-free pasta and confirm your broth is gluten-free.
• Herby twist: Add fresh basil or thyme to the sauce, or finish with a little chopped chives.
• Spicy kick: Increase red pepper flakes or add a pinch of cayenne to the blender.
• Lemon-pepper chicken: Season chicken with lemon pepper and a touch of paprika before searing for a bolder flavor.

FAQ

Can I make the sauce without a blender?

You’ll get the best texture with a blender, but a food processor works too. In a pinch, use an immersion blender directly in the pot.

Mash well first to help it along.

Can I use frozen cauliflower?

Yes. Frozen florets are convenient and cook quickly. Simmer until fully tender and proceed as directed.

What pasta shape works best?

Fettuccine is classic, but penne, rotini, or shells hold the sauce well.

Choose whole-wheat or legume-based pasta for extra fiber or protein.

Is there a way to make it vegetarian?

Absolutely. Skip the chicken and use vegetable broth. Add roasted chickpeas, sautéed mushrooms, or white beans for protein.

How do I keep the sauce from tasting bland?

Season in layers.

Salt the pasta water, season the chicken well, and adjust the sauce with salt, pepper, Parmesan, and lemon at the end. A little garlic goes a long way.

Can I prep this ahead?

Yes. Make the cauliflower sauce up to 3 days ahead and refrigerate.

Reheat gently and toss with freshly cooked pasta and chicken.

What can I use instead of Parmesan?

Pecorino Romano adds a sharper bite. For a lighter dairy touch, reduce the cheese and add nutritional yeast for savory depth.

How can I make it extra creamy?

Blend in 1–2 tablespoons of butter or a splash of milk when pureeing the sauce. Keep the heat low when reheating to maintain the silky texture.
