Creamy Alfredo sauce and tender chicken tucked into roasted zucchini boats make a dinner that feels both cozy and light. This dish delivers all the comfort of classic pasta Alfredo without the heavy carbs. It’s weeknight-friendly, naturally gluten-free, and easy to customize.
If you’ve been craving something rich yet balanced, this is a smart way to satisfy it. The best part: it looks impressive but comes together with everyday ingredients.
Ingredients
Method
- Prep the oven and pan: Heat oven to 400°F (200°C). Lightly oil a large baking dish.
- Prepare the zucchini boats: Slice each zucchini in half lengthwise. Use a spoon to scoop out the center seeds, leaving about 1/4-inch walls. Reserve about 1/2 cup of the chopped scooped flesh; pat it dry.
- Season and pre-bake: Brush zucchini with olive oil. Sprinkle with salt, pepper, and a pinch of Italian seasoning. Place cut side up in the dish and bake for 10–12 minutes to soften slightly.
- Make the Alfredo base: In a large skillet over medium heat, melt butter. Add garlic and sauté for 30–60 seconds until fragrant. Stir in heavy cream and cream cheese, whisking until smooth and lightly thickened, 3–4 minutes.
- Add cheeses and seasoning: Reduce heat to low. Stir in Parmesan until melted. Add Italian seasoning, red pepper flakes (if using), a little salt and pepper, and lemon zest. Taste and adjust seasoning.
- Add chicken and zucchini bits: Fold in the cooked chicken and the reserved chopped zucchini flesh. Simmer 1–2 minutes until everything is coated and warm.
- Fill the boats: Spoon the creamy chicken mixture evenly into the par-baked zucchini boats. Don’t overfill to the point of spilling.
- Top and bake: Sprinkle with mozzarella and a little extra Parmesan. Bake 12–15 minutes, until the cheese is melted and bubbling and the zucchini is tender but not mushy.
- Finish and serve: Let rest for 5 minutes. Garnish with chopped parsley. Add a crack of black pepper and a light squeeze of lemon if you like.

Storage Instructions
- Refrigerator: Store leftovers in an airtight container for up to 3 days.
- Freezer: Not ideal, as zucchini can release water and soften too much.
If needed, freeze tightly wrapped portions for up to 1 month and expect a softer texture.
- Reheating: Warm in a 325°F (165°C) oven for 10–15 minutes, or microwave in short intervals. If the sauce thickens too much, splash with a little cream or broth while reheating.
Benefits of This Recipe
- Keto-friendly: Low in carbs, high in fat and protein to help keep you satisfied.
- Nutrient-dense: Zucchini adds fiber, vitamin C, and hydration.
- Meal prep win: Makes great leftovers for quick lunches.
- Gluten-free: No flour needed thanks to cream cheese and Parmesan for thickening.
- Customizable: Easy to tweak flavors and add-ins to suit your taste.
Common Mistakes to Avoid
- Over-scooping the zucchini: Leave sturdy walls so the boats hold their shape.
- Skipping the pre-bake: Raw zucchini won’t soften enough under a short bake with filling.
- Boiling the sauce: High heat can cause separation. Keep it at a gentle simmer.
- Over-salting too early: Parmesan is salty.
Season after the cheese melts and you taste.
- Watery filling: Pat the scooped zucchini dry and don’t add too much liquid to the sauce.
Alternatives
- Protein swaps: Use shredded turkey, Italian sausage (cooked and drained), or shrimp. For shrimp, sauté separately and fold in at the end to avoid overcooking.
- Dairy tweaks: Replace part of the heavy cream with unsweetened almond milk and add extra cream cheese to keep it thick.
- Cheese variations: Try Asiago or Pecorino Romano with mozzarella for a sharper bite.
- Veggie add-ins: Fold in sautéed spinach, mushrooms, or chopped broccoli for extra volume and texture.
- Spice it up: Add a pinch of cayenne, paprika, or garlic powder to the sauce.
- Portion changes: Use small zucchinis for appetizer-sized boats, or hollow out large ones for a hearty entrée.
FAQ
How many carbs are in Keto Chicken Alfredo Stuffed Zucchini?
Exact numbers depend on brands and portions, but a typical serving (two halves) usually sits around 6–9 net carbs. Check your ingredient labels and measure portions for the most accurate macros.
Can I make this ahead?
Yes.
Assemble the boats up to the point before baking, cover, and refrigerate up to 24 hours. Add 5–8 extra minutes to the bake time. For best texture, wait to add the final cheese topping until just before baking.
What if my sauce is too thin?
Simmer a few extra minutes on low to reduce.
You can also whisk in another ounce of cream cheese or a bit more grated Parmesan to thicken without flour.
Can I use jarred Alfredo sauce?
You can, but check for added starches and sugars. If using jarred sauce, warm it gently and enrich with extra Parmesan and a knob of butter to boost flavor and fat.
How do I keep the zucchini from getting soggy?
Pre-bake the boats, pat the scooped flesh dry before adding it back, and avoid overbaking. Let the finished boats rest 5 minutes so the sauce sets before serving.
Is this kid-friendly?
Usually yes.
Keep the red pepper flakes light or skip them. The creamy sauce and melty cheese tend to be a hit with kids.
What sides go well with this?
Pair with a crisp green salad, roasted asparagus, or garlicky sautéed green beans. If not strictly keto, a small portion of cauliflower mash is great too.
