Keto Chicken Alfredo Stuffed Zucchini – A Creamy, Low-Carb Comfort Dish
Craving something creamy, cozy, and satisfying without the heavy carbs? Keto Chicken Alfredo Stuffed Zucchini checks all the boxes. It’s rich and cheesy with tender chicken, yet light enough to keep you on track.
The zucchini boats hold a luscious Alfredo filling, then bake to bubbly perfection. This is weeknight-friendly comfort food that feels special, whether you’re cooking for one or feeding a crowd.
Ingredients
Method
- Prep the oven and pan: Preheat oven to 400°F (200°C). Lightly grease a 9x13-inch baking dish.
- Prepare the zucchini boats: Trim the ends and slice each zucchini in half lengthwise. Use a spoon to scoop out the center, leaving a 1/4-inch border to form boats. Reserve about 1/2 cup of the chopped zucchini flesh, finely diced. Brush the boats with olive oil and season with salt and pepper. Place them cut-side up in the baking dish.
- Par-bake the zucchini: Bake for 10–12 minutes until just tender but not fully soft. This helps avoid watery results later. Remove and set aside.
- Make the Alfredo base: In a skillet over medium heat, melt the butter. Add garlic and sauté 30–60 seconds until fragrant. Stir in the reserved diced zucchini flesh and cook 2–3 minutes to soften.
- Build the sauce: Lower heat and whisk in the heavy cream and cream cheese. Stir until smooth and slightly thickened, 2–3 minutes. Add Parmesan, stirring until melted. Season with salt, pepper, and optional Italian seasoning or red pepper flakes.
- Add the chicken: Fold in the cooked chicken and any optional greens (spinach or broccoli). The mixture should be thick and creamy; if too thick, add a splash more cream. If too thin, simmer 1–2 minutes to reduce.
- Fill the boats: Spoon the chicken Alfredo mixture into each zucchini boat, packing it in evenly. Sprinkle mozzarella and a little extra Parmesan over the top.
- Bake to bubbly: Return the dish to the oven and bake 12–15 minutes, until the cheese is melted and golden in spots and the zucchini is tender.
- Finish and serve: Let rest 5 minutes. Garnish with chopped parsley. Taste and adjust salt and pepper if needed. Serve warm.

How to Store
Let leftovers cool completely, then store in an airtight container for up to 4 days in the refrigerator.
Reheat covered in a 350°F (175°C) oven for 10–15 minutes, or microwave in short bursts to avoid overcooking the zucchini. For freezing, place in a freezer-safe container for up to 2 months. Thaw overnight in the fridge before reheating.
Note: the zucchini will soften more after freezing, but the flavor stays great.
Why This is Good for You
- Low-carb and keto-friendly: Zucchini replaces pasta, slashing carbs while still delivering that creamy Alfredo vibe.
- Protein-rich: Chicken and cheese keep you full and satisfied, making this a solid main dish that won’t leave you hungry.
- Healthy fats: Butter, cream, and cheese provide fats that support ketosis and add richness without needing flour.
- Veggie boost: Zucchini adds fiber, potassium, and hydration, balancing the richness of the sauce.
Common Mistakes to Avoid
- Skipping the par-bake: Raw zucchini releases more water. Par-baking firms it up and prevents a watery dish.
- Overcooking the boats: Zucchini turns mushy fast. Aim for tender with a slight bite.
- Using pre-shredded cheese only: Bagged cheese often has anti-caking agents that prevent smooth melting.
Grate at least the Parmesan yourself for a silkier sauce.
- Too thin sauce: Alfredo should coat a spoon. Simmer briefly to reduce, or add a bit more Parmesan to thicken.
- Under-seasoning: Cream and cheese need salt and pepper to pop. Taste the filling before stuffing.
Variations You Can Try
- Bacon and mushroom: Sauté sliced mushrooms in a little bacon fat, add crumbled cooked bacon to the filling.
- Spinach artichoke: Fold in chopped spinach and drained, chopped artichoke hearts for a dip-inspired twist.
- Pesto Alfredo: Stir 1–2 tablespoons of basil pesto into the sauce for bright, herby flavor.
- Cajun kick: Add 1–2 teaspoons Cajun seasoning to the sauce and top with a pinch of red pepper flakes.
- Turkey or shrimp swap: Use leftover turkey or quickly sautéed shrimp instead of chicken.
If using shrimp, add just before baking to avoid overcooking.
- Three-cheese topper: Mix mozzarella with fontina and a touch of Romano for an extra-melty, savory crust.
FAQ
Can I make this ahead?
Yes. Assemble the stuffed zucchini up to the point of baking, cover, and refrigerate for up to 24 hours. Add 5–8 extra minutes to the bake time if going straight from the fridge.
For best texture, wait to add the cheese topping right before baking.
What can I use instead of heavy cream?
For keto, heavy cream is ideal. If you need a lighter option, try half-and-half, but simmer it a bit longer to reduce. Avoid milk-only versions, which can make the sauce thin and less rich.
How do I keep the sauce from separating?
Keep the heat moderate, add the cheeses slowly, and stir constantly.
Avoid boiling the sauce after adding cheese. If it starts to split, whisk in a tablespoon of cream off the heat to bring it back together.
Do I have to use cream cheese?
No, but it helps stabilize the sauce and adds body. If skipping it, add an extra 1/4 cup Parmesan and simmer a touch longer to thicken.
Is this gluten-free?
Yes, as written it’s naturally gluten-free.
Always check labels on cheeses and seasoning blends to be sure there are no hidden starches.
What if my zucchini are very large?
Large zucchini can be watery and have thicker skins. Scoop out more seeds, chop and drain the flesh, and plan for a slightly longer bake time. You may also need extra filling or cut them into thirds for easier portions.
Can I add onions?
Yes.
Sauté 1/4 to 1/2 cup finely diced onion in the butter before adding garlic. Cook until translucent to keep the sauce smooth and sweet.
How many carbs per serving?
Exact macros vary based on brands and portion sizes. As a general guide, one stuffed zucchini half typically lands around 5–7g net carbs.
