What You’ll Need

• Cooked chicken: 3 cups, shredded or cubed (rotisserie works great).
• Cauliflower florets or zucchini noodles: 4 cups.

  Cauliflower holds up best; zoodles are lighter.

• Butter: 3 tablespoons.
• Garlic: 3–4 cloves, minced.
• Heavy cream: 1 1/2 cups.
• Cream cheese: 4 ounces, softened (for extra creaminess and stability).
• Parmesan cheese: 1 cup, finely grated (freshly grated melts best).
• Mozzarella cheese: 1 1/2 cups, shredded, divided (part for sauce, part for topping).
• Chicken broth: 1/2 cup (low-sodium).
• Olive oil: 1 tablespoon (for roasting or sautéing the veggies).
• Seasonings: 1 teaspoon Italian seasoning, 1/2 teaspoon onion powder, 1/4 teaspoon red pepper flakes (optional).
• Salt and black pepper: To taste.
• Fresh parsley: 2 tablespoons, chopped (for garnish).

Step-by-Step Instructions

Save

1. Prep the oven and pan: Preheat to 375°F (190°C). Grease a 9×13-inch baking dish or similar casserole dish.
2. Cook the veggies: If using cauliflower, toss florets with olive oil, salt, and pepper. Roast on a sheet pan for 15–20 minutes until just tender.

   If using zoodles, sauté for 2–3 minutes in a dry skillet to release moisture; drain well.

3. Warm the chicken: If using cold rotisserie chicken, roughly chop or shred. Set aside.
4. Make the Alfredo sauce: In a large skillet over medium heat, melt butter. Add garlic and cook 30–60 seconds until fragrant.

   Stir in heavy cream and chicken broth. Add cream cheese in small pieces, whisking until smooth.

5. Season and thicken: Add Italian seasoning, onion powder, red pepper flakes (if using), salt, and pepper. Simmer 3–4 minutes until slightly thickened.
6. Add the cheeses: Whisk in Parmesan and 1/2 cup mozzarella until melted and silky.

   Taste and adjust salt and pepper.

7. Combine: In a large bowl, toss the cooked cauliflower or zoodles with the chicken and Alfredo sauce until everything is evenly coated.
8. Assemble: Transfer the mixture to the baking dish. Top with remaining mozzarella and an extra sprinkle of Parmesan if you like a crispier crust.
9. Bake: Bake 18–22 minutes, until bubbling around the edges and the top is melted and lightly golden.
10. Optional broil: For a deeper color, broil 1–2 minutes, watching closely.
11. Rest and serve: Let it rest 5–10 minutes so it sets. Sprinkle with fresh parsley and serve warm.

How to Store

• Refrigerator: Store leftovers in an airtight container for 3–4 days.

  Reheat gently in the oven at 325°F or in the microwave at 50–60% power to avoid breaking the sauce.

• Freezer: Freeze the baked or unbaked casserole for up to 2 months. Wrap tightly with plastic and foil. Thaw overnight in the fridge before baking or reheating.
• Make-ahead: Assemble up to 24 hours ahead and refrigerate.

  Add 5–10 minutes to the bake time if starting cold.

Benefits of This Recipe

• Low in carbs: Swapping pasta for cauliflower or zucchini dramatically reduces carbs without sacrificing comfort.
• High in protein: Chicken and cheese help keep you full and support muscle maintenance.
• Simple ingredients: Mostly pantry and fridge staples you can find anywhere.
• Great for families: The creamy, cheesy flavor appeals to picky eaters while still being nutrient-dense.
• Flexible for diets: Easy to make gluten-free and keto-friendly with the listed ingredients.

Pitfalls to Watch Out For

• Watery casserole: Zucchini releases a lot of moisture. Sauté it briefly and drain, or choose roasted cauliflower for a firmer bake.
• Broken sauce: Overheating can cause the sauce to separate. Keep the heat medium and whisk until just melted and smooth.
• Over-salting: Parmesan is salty.

  Taste the sauce before adding extra salt, especially if using regular (not low-sodium) broth.

• Rubbery chicken: Overcooked chicken dries out in the oven. Use pre-cooked chicken that’s still moist or poach gently before baking.
• Greasy top: Too much cheese or not enough veggies can make it heavy. Stick to the amounts listed for a balanced texture.

Variations You Can Try

• Broccoli Alfredo Bake: Swap half or all of the cauliflower with roasted broccoli florets for a pop of color and extra fiber.
• Spinach and Artichoke: Stir in 2 cups fresh spinach (wilted) and 1 cup chopped artichoke hearts for a dip-inspired twist.
• Bacon and Mushroom: Sauté sliced mushrooms in a little butter, stir into the mix, and top with crumbled cooked bacon before baking.
• Three-Cheese Upgrade: Add 1/2 cup shredded provolone or fontina for a deeper, melty flavor.
• Dairy-Light Option: Use half-and-half and reduce the Parmesan slightly.

  The sauce will be thinner but still tasty; add an extra ounce of cream cheese to stabilize.

• Spicy Alfredo: Increase red pepper flakes or add a dash of hot sauce to the sauce for gentle heat.
• Pesto Swirl: Stir 2–3 tablespoons of basil pesto into the sauce for a fresh, herby note.

FAQ

Can I use store-bought Alfredo sauce?

Yes, but check the label for added sugars and starches if you’re keeping it low-carb. Warm it gently and whisk in a little Parmesan and cream cheese to thicken and boost flavor.

What’s the best vegetable base for the lowest carbs?

Cauliflower is the most reliable option for texture and carb count. Zucchini works too but needs extra moisture control.

Broccoli is a solid middle ground.

Can I use raw chicken?

You can, but cook it first for the best texture and food safety. Sauté bite-sized pieces in a little oil until just cooked, then proceed with the recipe.

How do I keep the sauce from splitting when reheating?

Use gentle heat. Reheat at 50–60% power in the microwave, stirring halfway, or cover and warm in the oven at 325°F until heated through.

Is there a way to make it egg-free and gluten-free?

This recipe is naturally egg-free and gluten-free as written.

Just ensure your broth and cheeses are gluten-free if you’re sensitive.

Can I lower the calories without losing flavor?

Use half-and-half instead of heavy cream and reduce mozzarella by 1/2 cup. Add extra roasted veggies for volume, and season well to keep it satisfying.

What can I serve with it?

A crisp green salad with lemon vinaigrette or roasted asparagus keeps the meal light. Garlic-roasted mushrooms also pair nicely.
