Though I’m usually a fan of marinara, my kids adore Alfredo sauce. They’ve been asking for a new recipe, so I figured I’d create a keto-friendly version we could all enjoy. The result? A creamy, rich Alfredo sauce that’s so good, no one will know it’s low-carb.
My husband and I can savor this keto dish as is, while the kids can have theirs over pasta, making dinner a breeze for the whole family. This is definitely one for your keto meal plan, alongside other easy chicken recipes.

To get started, melt butter in a cast-iron skillet, then add the seasoned chicken breast to brown. If you prefer, olive oil works just as well. I cut the chicken into uniform pieces so they cook evenly.
Can I Use Chicken Thighs Instead of Breasts?
Absolutely! While I prefer boneless, skinless chicken breasts, thighs work just as well and add a bit more fat, which is great for a high-fat keto diet.
Can I Use Precooked Chicken?
Yes, precooked chicken can save time. If you use rotisserie chicken, this meal can be ready in under 15 minutes. Just be sure you’re okay with the ingredients in your precooked chicken.
For an extra kick, I added Pepper Jack cheese to the traditional Parmesan Alfredo sauce. It didn’t make the dish spicy, which is great for my younger kids. But if you like a bit of heat, you can always add red pepper flakes or fresh jalapeños.
When making the keto Alfredo sauce, it’s important to bring it to a slow boil and whisk continuously to reduce and thicken it without sticking to the skillet. Keep the heat low to prevent the cream from scalding or curdling.
Tip: Avoid covering the skillet with a lid, as condensation can make the sauce watery.

How to Thicken Keto Alfredo Sauce Without Flour
While traditional sauces use flour or cornstarch, this low-carb Alfredo sauce thickens nicely by simply simmering it uncovered. The combination of heavy cream, cream cheese, and cheeses will give you a rich, thick sauce without needing flour.
I used a 12-ounce steam bag of broccoli for convenience, but fresh broccoli works great too. Once steamed, add the chicken and broccoli to the Alfredo sauce.
Tip: If you want a meatless dish, omit the chicken and increase the broccoli for a keto-friendly broccoli Alfredo bake.
Tip: Be sure to drain the broccoli after steaming to avoid thinning out the sauce.
Can I Use a Different Veggie?
Feel free to swap out broccoli for another low-carb veggie. Here are a few ideas:
- Asparagus
- Brussels sprouts
- Green beans
- Cauliflower
- Mushrooms

I like to pop the skillet in the oven to brown the mozzarella cheese on top, but you can continue to simmer on the stove until the cheese melts. Just avoid using a lid, as condensation can thin the sauce.
For a simple, one-dish meal, serve this creamy, delicious low-carb Chicken Alfredo Bake as is, or pair it with one of the low-carb pasta alternatives listed below. A leafy garden salad would also be a great side. If you miss bread, try some cheesy garlic chaffles as a low-carb substitute for garlic bread.

Low-Carb Pasta Alternatives:
- Zucchini Zoodles: Made by spiralizing zucchini. A spiralizer is inexpensive and works great.
- Spaghetti Squash: My favorite pasta alternative. Once cooked, it shreds into thin strands that resemble noodles and is rich in fiber, vitamins, and minerals.
- Miracle Noodles (Shirataki Noodles): Made from the Konjac plant, they’re very low in carbs. Be sure to rinse them well to neutralize their smell.
- Palmini: Featured on Shark Tank, this pasta alternative is made from hearts of palm and has only 4g of carbs (2g net) per serving.

How Many Net Carbs in Alfredo Sauce?
Alfredo sauce is usually low in carbs, but store-bought brands may contain ingredients like wheat or flour. This Keto Chicken Alfredo with Broccoli recipe has just 5 net carbs per serving, including the broccoli.
How to Reheat Keto Alfredo Sauce Without It Separating
Reheating Alfredo sauce without it separating can be tricky. The key is to avoid shocking it with high heat. Here are a couple of methods that work best:
- Skillet: Add a bit of heavy cream to a skillet over medium heat, then slowly add the Alfredo sauce.
- Double Boiler: Reheat slowly using a double boiler.
- Oven: Warm in the oven at 375°F. Add a bit of water to the dish first.
