Keto & Low-Carb
Keto Chicken Alfredo Zoodles
Zucchini noodles stand in for pasta in this rich, garlicky alfredo, keeping the dish genuinely low-carb without sacrificing the creamy, parmesan-heavy sauce the dish is loved for. The key is cooking the zoodles briefly and separately so they don't water down the sauce.
Why you'll love this recipe
- Genuinely low-carb without sacrificing creaminess
- Zucchini noodles cook in minutes
- Rich, garlicky parmesan sauce
- Naturally gluten-free
Instructions
- Toss the zucchini noodles with 1/2 tsp salt and let them sit in a colander for 10-15 minutes to release excess water, then pat dry with paper towels.
- Season the diced chicken with the remaining salt and pepper.
- Heat olive oil in a large skillet over medium-high heat and cook the chicken for 6-7 minutes, until golden and cooked through. Remove to a plate.
- In the same skillet, melt the butter and add the garlic, cooking for 30 seconds until fragrant.
- Pour in the heavy cream and bring to a gentle simmer. Whisk in the parmesan until melted and smooth.
- Return the chicken to the sauce, then add the zucchini noodles and toss gently for 1-2 minutes, just until warmed through and slightly softened.
- Garnish with parsley and serve immediately.
How to tell it's done
The diced chicken is done after 6-7 minutes, when it's golden on the outside and opaque in the center (165°F/74°C). The zoodles only need 1-2 minutes in the sauce. They should be warm and just starting to soften but still have a slight bite. If they turn limp and the sauce looks thin and watery, they've cooked too long.
Tips for success
- Salting the zucchini noodles and letting them drain is essential — skipping this step leads to a watery, thin sauce.
- Add the zoodles at the very end and toss only briefly; overcooking turns them mushy and releases even more water.
- Use a good-quality, finely grated parmesan for the smoothest sauce.
- This dish is best served immediately, since zucchini noodles continue to release water as they sit.
Ingredient notes & swaps
- Zucchini: medium zucchini (about 8 inches) spiralize best. Very large ones are watery and seedy. Store-bought spiralized zucchini works if you dry it well.
- Other noodles: hearts of palm noodles or shirataki noodles hold up better than zucchini and release less water. Rinse and dry shirataki thoroughly.
- Parmesan: freshly grated parmesan melts smoothly. Add it off the boil so it doesn't clump or turn grainy.
- Chicken: diced boneless thighs stay juicier and fit keto macros well.
Storage & reheating
Leftovers are best eaten within a day or two. The zucchini keeps releasing water and thins the sauce. Store in the fridge for up to 2 days and reheat gently in a skillet over low heat, then simmer for a minute to reduce any extra liquid.
Make ahead & freezing
Cook the chicken and make the alfredo sauce up to 3 days ahead and store them together. Spiralize the zucchini ahead too, but salt and drain it only just before cooking. When it's time to eat, reheat the sauce and chicken, then toss in the drained zoodles. Not recommended for freezing.
What to serve with it
A simple arugula salad with lemon and olive oil, roasted asparagus, or garlic-sautéed spinach keeps the meal low-carb. Add sautéed mushrooms or sun-dried tomatoes to the sauce for more flavor.
Frequently asked questions
Why is my zucchini alfredo watery?
Zucchini releases a lot of water as it cooks; salting and draining the noodles beforehand, and adding them only at the very end, both help minimize this.
Can I use a different low-carb noodle?
Yes, spaghetti squash or shirataki noodles both work as alternatives to zucchini.
Can I make the sauce ahead and add the zoodles later?
Yes, the alfredo sauce and chicken can be made ahead and reheated; add fresh zucchini noodles just before serving.
Is this recipe keto-friendly?
Yes, it's naturally low in carbs and high in fat, making it well-suited to a keto diet.
