Ingredients
Method
- Prep the chicken: Pat the chicken dry. If thick, butterfly or pound to about 1/2 inch for even cooking. Season both sides with salt, pepper, Italian seasoning, paprika, and onion powder.
- Sear the chicken: Heat olive oil in a large skillet over medium-high. Add chicken in a single layer and sear 3–4 minutes per side until golden and cooked through. Transfer to a plate and tent loosely with foil.
- Build the sauce base: Lower heat to medium. Add butter to the skillet. Stir in garlic and cook 30 seconds until fragrant, scraping up browned bits for extra flavor.
- Deglaze and simmer: Pour in chicken broth and simmer 1–2 minutes to reduce slightly. Stir in heavy cream and bring to a gentle simmer. Do not boil hard; keep it soft and steady.
- Add cheese and thicken: Whisk in Parmesan until melted and smooth. If you like heat, add a pinch of red pepper flakes. Simmer 2–3 minutes until lightly thickened.
- Wilt the spinach: Add spinach in batches, stirring until it shrinks and fits. Cook 1–2 minutes until just wilted but still bright green.
- Finish with chicken: Return chicken and any juices to the skillet. Spoon sauce over the top. Simmer 1–2 minutes to warm through and let flavors mingle. Add lemon juice and taste; adjust salt and pepper.
- Garnish and serve: Sprinkle with chopped parsley. Serve as-is, or pair with zucchini noodles, cauliflower rice, or a simple green salad.
What Makes This Recipe So Good

What You’ll Need
- 1.25–1.5 pounds boneless, skinless chicken breasts (thinly sliced or pounded to even thickness; thighs also work)
- 2 tablespoons olive oil (or avocado oil)
- 2 tablespoons butter
- 3–4 cloves garlic, minced
- 1 teaspoon Italian seasoning (or a mix of oregano, thyme, and basil)

- 1 teaspoon sea salt (plus more to taste)
- 1/2 teaspoon black pepper
- 1/2 cup chicken broth (low-sodium)
- 3/4 cup heavy cream
- 1/2 cup grated Parmesan cheese (freshly grated melts best)
- 4–5 cups fresh baby spinach (about 5 ounces)
- 1 tablespoon lemon juice (plus extra wedges for serving)
- Optional add-ins: red pepper flakes, a handful of sun-dried tomatoes (not oil-packed or well-drained), sliced mushrooms, or cooked bacon crumbles
- Fresh parsley (for garnish)
Instructions
- Prep the chicken: Pat the chicken dry. If thick, butterfly or pound to about 1/2 inch for even cooking.
Season both sides with salt, pepper, Italian seasoning, paprika, and onion powder.
- Sear the chicken: Heat olive oil in a large skillet over medium-high. Add chicken in a single layer and sear 3–4 minutes per side until golden and cooked through. Transfer to a plate and tent loosely with foil.
- Build the sauce base: Lower heat to medium.
Add butter to the skillet. Stir in garlic and cook 30 seconds until fragrant, scraping up browned bits for extra flavor.
- Deglaze and simmer: Pour in chicken broth and simmer 1–2 minutes to reduce slightly. Stir in heavy cream and bring to a gentle simmer.
Do not boil hard; keep it soft and steady.
- Add cheese and thicken: Whisk in Parmesan until melted and smooth. If you like heat, add a pinch of red pepper flakes. Simmer 2–3 minutes until lightly thickened.
- Wilt the spinach: Add spinach in batches, stirring until it shrinks and fits.
Cook 1–2 minutes until just wilted but still bright green.

Storage Instructions
- Refrigerate: Cool completely, then store in an airtight container for up to 4 days.
- Freeze: Cream sauces can separate when frozen. If you must freeze, do so for up to 2 months and reheat gently, whisking as needed.
For best texture, enjoy fresh or refrigerated only.
- Reheat: Warm in a covered skillet over low heat with a splash of broth or cream, stirring occasionally. Avoid high heat to prevent the sauce from breaking.
Benefits of This Recipe
- Keto-aligned macros: High in protein and healthy fats, low in carbs, making it easy to fit into daily goals.
- Nutrient-dense greens: Spinach adds iron, folate, vitamin K, and a gentle earthiness that balances the rich sauce.
- Satiating without heaviness: Cream and cheese give richness that keeps you full, yet the lemon keeps the dish bright.
- Budget-friendly: Uses basic pantry items and stretches a few chicken breasts into a full, hearty meal.
- Great for meal prep: Holds up well for a few days and reheats easily for quick lunches.
What Not to Do
- Don’t crowd the pan: Overlapping chicken steams it instead of searing. Cook in batches if needed.
- Don’t boil the cream: A rolling boil can make the sauce split.
Keep the heat moderate and the simmer gentle.
- Don’t skip salting the chicken: Seasoning the meat directly is key to building flavor from the start.
- Don’t add spinach too early: Add it near the end so it stays vibrant and doesn’t turn mushy.
- Don’t rely only on cheese for thickness: Give the sauce a minute to reduce before adding Parmesan for the best texture.
Alternatives
- Protein swaps: Try chicken thighs for extra juiciness, or use turkey cutlets or shrimp. For shrimp, sear 1–2 minutes per side and add back at the very end.
- Dairy-free option: Use full-fat coconut milk instead of cream and nutritional yeast instead of Parmesan. Flavor will be slightly sweeter; add extra lemon and salt to balance.
- Veggie boosts: Sauté mushrooms after removing the chicken, or stir in roasted cherry tomatoes, artichoke hearts, or zucchini ribbons.
- Spice it up: Add crushed red pepper, a dash of Cajun seasoning, or a spoon of pesto for a different vibe.
- Garnish ideas: Top with crispy bacon bits, toasted pine nuts, or a shower of fresh basil.
FAQ
Is this recipe truly keto?
Yes.
It’s low in net carbs thanks to spinach and a cream-based sauce, and it includes plenty of fat and protein. Pair it with non-starchy sides like cauliflower rice or zucchini noodles to keep it fully keto.
Can I use frozen spinach?
You can. Thaw and squeeze out as much water as possible before adding it.
Start with about 1 to 1.5 cups of frozen spinach and add more if you like.
What if my sauce splits?
Lower the heat and whisk in a small splash of cream or broth until it comes back together. Avoid boiling after adding cream and cheese to prevent curdling.
How do I know the chicken is done?
Slices should be opaque and firm with clear juices. If you use a thermometer, aim for an internal temperature of 165°F (74°C) at the thickest part.
Can I make this without Parmesan?
Yes.
Use Pecorino Romano for a sharper bite, or try a keto-friendly shredded Italian blend. If skipping cheese entirely, simmer the cream a bit longer to reduce and thicken.
What can I serve with it?
Great sides include sautéed zucchini, roasted broccoli, cauliflower mash, or a simple arugula salad with olive oil and lemon.
Can I meal prep this?
Absolutely. Portion into containers with a low-carb side and refrigerate up to 4 days.
Reheat gently with a splash of cream or broth to keep the sauce silky.
Will chicken thighs change the cook time?
Boneless, skinless thighs cook in about the same time if cut thin. If left whole and thicker, add a couple of minutes per side and check doneness with a thermometer.
Can I make it spicier?
Yes. Add 1/4 to 1/2 teaspoon red pepper flakes with the garlic, or finish with hot sauce to taste.
How can I lighten it up?
Use half-and-half instead of heavy cream and reduce a bit longer.
It won’t be as rich, but it will still be creamy and flavorful.
