What You’ll Need

• 2 to 2.5 pounds boneless, skinless chicken breasts (or thighs for extra tenderness)
• 1 cup chicken broth (low sodium)
• 1 cup heavy whipping cream
• 4 ounces cream cheese, softened and cut into chunks
• 1 cup freshly grated Parmesan cheese (plus extra for serving)
• 3 cloves garlic, minced
• 1 teaspoon Italian seasoning
• 1/2 teaspoon onion powder
• 1/2 teaspoon kosher salt, more to taste
• 1/2 teaspoon black pepper
• 2 tablespoons unsalted butter
• 1/4 teaspoon red pepper flakes (optional, for gentle heat)
• Fresh parsley, chopped, for garnish
• Low-carb base for serving: zucchini noodles, steamed broccoli, spaghetti squash, shirataki noodles, or cauliflower rice

How to Make It

1. Prep the slow cooker: Lightly grease the insert or use a liner for easy cleanup.
2. Season the chicken: Pat chicken dry.

   Sprinkle with salt, pepper, Italian seasoning, and onion powder on both sides.

3. Add the base: Place chicken in the slow cooker. Add chicken broth and minced garlic around the chicken.
4. Low and slow: Cover and cook on Low for 3.5 to 4.5 hours, or on High for 2 to 3 hours, until chicken is just cooked through and tender.
5. Shred or slice: Remove the chicken to a cutting board. Shred with two forks or slice into bite-size pieces.

   Return it to the slow cooker.

6. Enrich the sauce: Add heavy cream, cream cheese, butter, and Parmesan to the slow cooker. Stir until the cream cheese begins to melt. Cover and cook on Low for 20 to 30 minutes.
7. Finish and thicken: Stir well to fully combine.

   If the sauce looks thin, leave the lid off and cook on High for 10 to 15 minutes to reduce. If very thick, splash in a bit more broth or cream.

8. Adjust seasoning: Taste and add more salt, pepper, or red pepper flakes if you like a little heat.
9. Serve: Spoon over zucchini noodles, steamed broccoli, or your favorite keto base. Top with extra Parmesan and parsley.

How to Store

• Refrigerate: Cool completely, then store in an airtight container for up to 4 days.
• Freeze: Freeze in portioned containers for up to 2 months.

  Thaw overnight in the fridge for best texture.

• Reheat: Warm gently on the stovetop over low heat or in the microwave at 50% power, stirring occasionally. Add a splash of cream or broth to loosen the sauce if needed.

Health Benefits

• Keto-friendly macros: Low carb count supports ketosis while the fats keep you full and satisfied.
• High-quality protein: Chicken provides essential amino acids for muscle repair and overall health.
• Calcium and fat-soluble vitamins: Parmesan and cream contribute calcium and help absorption of fat-soluble nutrients in veggies served alongside.
• Simple, whole ingredients: No flour, no processed thickeners, and you control the sodium.

Common Mistakes to Avoid

• Overcooking the chicken: Dry chicken happens fast. Check for doneness toward the early end of the time range.
• Adding dairy too early: Cream and cream cheese can separate if cooked for hours.

  Add them near the end as directed.

• Using pre-shredded Parmesan: Bagged cheese often contains anti-caking agents that make the sauce grainy. Freshly grated melts smoother.
• Cranking the heat: Boiling dairy sauce can cause curdling. Keep it low and gentle.
• Skipping seasoning: Taste before serving.

  A pinch of salt or squeeze of lemon can brighten the whole dish.

Variations You Can Try

• Chicken thigh version: Swap breasts for boneless skinless thighs for richer flavor and extra tenderness.
• Garlic mushroom Alfredo: Stir in sautéed mushrooms in the final 20 minutes for an earthy twist.
• Spinach Alfredo: Add 2 cups of fresh spinach during the last 5 minutes until just wilted.
• Lemon herb: Add 1 teaspoon lemon zest and a squeeze of lemon at the end for brightness.
• Bacon Alfredo: Crumble in 3 to 4 slices of crisp-cooked bacon before serving for a smoky note.
• Dairy-light option: Replace half the cream with unsweetened, full-fat coconut milk and use a bit less Parmesan for a lighter feel.

FAQ

Can I use frozen chicken?

It’s safer and more consistent to use thawed chicken in a slow cooker. Frozen chicken can linger at unsafe temperatures too long. If starting from frozen, fully thaw in the refrigerator first.

How can I thicken the sauce without flour?

Let the sauce simmer uncovered on High for 10 to 15 minutes to reduce, or add a bit more Parmesan.

Cream cheese also helps create body without starch.

What can I serve this with to keep it keto?

Zucchini noodles, steamed broccoli, cauliflower rice, spaghetti squash, or shirataki noodles all work well. Keep portions of veggie “noodles” generous for a satisfying plate.

Can I make it on the stovetop instead?

Yes. Poach or sauté the chicken until cooked, slice or shred, then simmer gently with broth, cream, cream cheese, and Parmesan until smooth.

Keep the heat low to avoid curdling.

Is there a way to lower the calories?

Use chicken breasts, reduce butter to 1 tablespoon, and thin the sauce with a bit more broth. You’ll still get creamy texture while easing up on richness.

How do I prevent a grainy sauce?

Use freshly grated Parmesan, add dairy at the end, and avoid boiling. Stir until melted and smooth, then serve promptly.
