My mom used to make chicken alfredo every Friday night. The smell of garlic and cream would fill the entire house. When I switched to keto, I thought those Friday nights were over. Then I realized – the sauce was already low carb. I just needed to skip the pasta and maybe add a few tweaks.
This keto creamy chicken Alfredo is ready in about 30 minutes, requires basic cooking skills, and tastes incredibly rich and indulgent. The flavor profile is creamy, garlicky, and savory with a nice peppery kick. You won’t miss the carbs, I promise.
Why This Keto Chicken Alfredo Works
Traditional alfredo sauce is basically keto already. Heavy cream, butter, and parmesan cheese are all low in carbs. The only problem was always the pasta. This recipe focuses on perfectly seasoned chicken swimming in that classic velvety sauce. You can serve it over zucchini noodles, cauliflower rice, or just eat it straight from the pan like I sometimes do.
The chicken stays juicy because we’re pan-searing it first, then letting it finish in the sauce. The sauce itself is foolproof. As long as you use freshly grated parmesan (not the pre-grated stuff), it’ll turn out smooth and creamy every single time.
Ingredients You’ll Need
For the Chicken
- 1.5 lbs (680g) boneless, skinless chicken breasts
- 2 tsp Italian seasoning
- 1 tsp garlic powder
- 1 tsp salt
- ½ tsp black pepper
- 2 tbsp olive oil or avocado oil
For the Alfredo Sauce
- 3 tbsp unsalted butter
- 4 cloves garlic, minced (about 1 tbsp)
- 1½ cups (360ml) heavy cream
- 1 cup (100g) freshly grated parmesan cheese
- ½ tsp salt
- ¼ tsp black pepper
- ¼ tsp nutmeg (optional, but really good)
- Fresh parsley for garnish
Substitutes: You can use chicken thighs instead of breasts for more flavor. If you can’t find fresh parmesan, use the best quality pre-grated you can find, but add it slowly because it might not melt as smoothly. For dairy-free, this won’t work well since cream and parmesan are essential to the recipe.
How to Make Keto Creamy Chicken Alfredo
Step 1: Prepare the Chicken
Slice the chicken breasts horizontally to create thinner cutlets, about ½ inch thick. This helps them cook faster and more evenly. Pat them completely dry with paper towels. Mix the Italian seasoning, garlic powder, salt, and pepper in a small bowl. Season both sides of the chicken generously with this mixture.
Step 2: Sear the Chicken
Heat the oil in a large skillet over medium-high heat for about 2 minutes. Add the chicken cutlets without crowding the pan. Cook for 5-6 minutes on the first side without moving them. This creates a golden-brown crust. Flip and cook for another 4-5 minutes until the internal temperature reaches 165°F (74°C). Remove chicken to a plate and tent with foil.
Step 3: Start the Sauce
Reduce heat to medium. Add butter to the same skillet. Once melted and foaming (about 30 seconds), add the minced garlic. Stir constantly for 45-60 seconds until fragrant but not browned. Garlic burns quickly, so watch it carefully.
Step 4: Add the Cream
Pour in the heavy cream and stir to scrape up any browned bits from the bottom of the pan. These bits add tons of flavor. Bring to a gentle simmer, then reduce heat to medium-low. Let it simmer for 3-4 minutes, stirring occasionally. The cream will thicken slightly.
Step 5: Melt in the Cheese
Remove the skillet from heat. Add the parmesan cheese in three additions, stirring constantly until each addition melts completely before adding more. This prevents clumping. Once all the cheese is incorporated, stir in the salt, pepper, and nutmeg if using. The sauce should coat the back of a spoon.
Step 6: Combine Everything
Return the skillet to low heat. Slice the chicken into strips. Add the chicken and any accumulated juices back to the sauce. Gently toss to coat everything. Let it warm through for 2-3 minutes. If the sauce is too thick, thin it with a tablespoon of water or cream at a time.
Step 7: Serve
Remove from heat. Garnish with freshly chopped parsley and extra parmesan if desired. Serve immediately while hot.
Serving Suggestions
This creamy chicken alfredo pairs beautifully with several low-carb sides. Zucchini noodles are the most obvious choice. You can also serve it over steamed broccoli, roasted asparagus, or even cauliflower rice. Sometimes I just eat it with a side salad for a complete meal.
If you’re not strictly keto, serving it over regular pasta works perfectly. The sauce measurements here are enough for about 8 oz of pasta. My non-keto family members love it this way and never notice I’m eating mine differently.
Storage and Reheating Tips
Store leftovers in an airtight container in the refrigerator for up to 3 days. The sauce might separate slightly when cold, but that’s normal. To reheat, use low heat on the stovetop with a splash of cream or water. Stir constantly until warmed through and the sauce comes back together. Don’t microwave on high power or the cream will break.
I don’t recommend freezing this because cream sauces can separate when thawed. If you do freeze it, thaw in the refrigerator overnight and reheat gently on the stovetop, whisking constantly.
What Makes This Different from Regular Alfredo
The traditional creamy chicken alfredo pasta would be loaded with carbs from the noodles. A typical serving has around 60-80g of carbs. This version keeps you under 5g of net carbs per serving because there’s no pasta involved. You’re getting all the flavor and satisfaction without the blood sugar spike.
I also use more chicken than a typical pasta dish would. This makes it more filling and adds protein. Each serving has about 35-40g of protein, which helps keep you full for hours. The fat from the cream and cheese provides energy on a keto diet.
Common Mistakes to Avoid
The biggest mistake is using pre-grated parmesan. It contains anti-caking agents that prevent smooth melting. You’ll end up with a grainy sauce. Always grate your own cheese right before using it.
Another issue is cooking on too high heat. If the cream boils hard, it can break and look curdled. Keep it at a gentle simmer. If your sauce does break, remove from heat and whisk in a tablespoon of cold cream. That usually brings it back together.
Don’t overcook the chicken. Dry chicken ruins the whole dish. Use a meat thermometer and pull it at exactly 165°F. The residual heat will finish cooking it while it rests.
Variations to Try
Add some vegetables directly to the sauce. Spinach works great – just stir in a few handfuls during the last minute of cooking. Sun-dried tomatoes add a nice tangy sweetness. Mushrooms sautéed with the garlic are also excellent.
For a cajun twist, add 1-2 tsp of cajun seasoning to the chicken and a pinch to the sauce. This gives it a spicy kick similar to what you’d find at popular chain restaurants. You could also try this approach with salmon instead of chicken.
If you want to add some crunch, top with crispy bacon pieces or toasted pine nuts right before serving.
