Keto Creamy Pesto Chicken – A Comforting, Low-Carb Skillet Dinner
This is the kind of weeknight recipe you make once and then keep on repeat. Tender chicken simmered in a rich pesto cream sauce feels cozy and indulgent, but it stays firmly low-carb. The sauce clings to every bite, with garlicky basil and a hint of lemon lifting the flavor.
It cooks in one pan, uses simple ingredients, and tastes like something you’d order at a favorite bistro. If you’re craving a satisfying meal without the carb crash, this one checks every box.
Ingredients
Method
- Prep the chicken: Pat chicken dry. Season both sides with salt and pepper. For faster cooking, pound breasts to even thickness or slice into cutlets.
- Heat the pan: In a large skillet, warm olive oil over medium-high heat. Add butter if using for extra browning and flavor.
- Brown the chicken: Sear chicken 4–6 minutes per side until golden and mostly cooked through. Remove to a plate and tent loosely with foil.
- Sauté the garlic: Lower heat to medium. Add minced garlic to the pan and cook 30 seconds until fragrant. Don’t let it burn.
- Deglaze: Pour in chicken broth. Scrape up browned bits with a wooden spoon. Let it simmer 1–2 minutes to reduce slightly.
- Make it creamy: Stir in heavy cream and bring to a gentle simmer. Keep the heat moderate to avoid curdling or boiling over.
- Add pesto and cheese: Whisk in pesto and Parmesan. Taste and adjust salt. Add a pinch of red pepper flakes if you like heat.
- Finish the chicken: Return chicken and any juices to the pan. Simmer 3–5 minutes, turning once, until chicken is cooked through and sauce thickens.
- Brighten it up: Squeeze in lemon juice to taste and, if you like, a little zest. This balances the richness.
- Wilt the greens: Fold in spinach and cook 1 minute until just wilted. Sauce should be glossy and coat the chicken.
- Serve: Garnish with fresh basil and extra Parmesan. Serve hot with zoodles, cauliflower rice, or sautéed asparagus.
Why This Recipe Works
High fat, low carb balance: The pesto and cream provide rich fats that keep you full, while chicken delivers lean protein without carbs.
One-pan ease: Browning the chicken first builds flavor, and deglazing with broth pulls all those browned bits into the sauce.
Customizable and forgiving: Use store-bought pesto or homemade. Add spinach, cherry tomatoes, or mushrooms without throwing off the macros too much.
Fast but special: Ready in about 30 minutes, yet the creamy pesto sauce makes it feel restaurant-worthy.

How to Store
Refrigerator: Store leftovers in an airtight container for up to 3–4 days.
The sauce may thicken as it cools.
Reheating: Warm gently in a covered skillet over low heat with a splash of broth or cream to loosen the sauce. Avoid boiling to prevent separation.
Freezer: Cream sauces can separate when frozen, but this dish can be frozen up to 2 months if needed. Thaw overnight in the fridge and reheat slowly, whisking to bring the sauce back together.
Why This is Good for You
Keto-friendly macros: This dish is low in carbs and higher in fat, which supports ketosis for those following a ketogenic plan.
Protein for satiety: Chicken provides a steady source of protein to support muscle maintenance and keep you satisfied.
Herbs and micronutrients: Basil pesto contains antioxidants and healthy fats from olive oil and nuts.
Spinach adds iron, folate, and vitamin K.
Steady energy: The fat and protein balance can help reduce blood sugar spikes and keep you full longer.
Pitfalls to Watch Out For
- Overcooking the chicken: Dry chicken ruins the dish. Use even thickness cutlets and pull from heat when it hits 165°F (74°C).
- Boiling the cream: A rolling boil can break the sauce. Keep it at a gentle simmer and stir often.
- Salty pesto: Store-bought pesto and Parmesan can be salty.
Taste before adding extra salt.
- Too thin or too thick sauce: If too thin, simmer a few more minutes. If too thick, add a splash of broth or cream.
- Hidden carbs in pesto: Some brands add sugar. Check labels and choose a clean, low-carb pesto.
Alternatives
- Protein swaps: Use boneless thighs for extra juiciness, or try turkey cutlets.
Shrimp also works; cook quickly and add at the end.
- Dairy-free option: Use full-fat coconut milk instead of cream and a dairy-free pesto. Skip the Parmesan or use a dairy-free alternative.
- Nut-free pesto: Make pesto with pumpkin seeds or sunflower seeds instead of pine nuts.
- Flavor twists: Add sun-dried tomatoes, sautéed mushrooms, or a spoon of mascarpone for extra silkiness.
- Greens swap: Use kale (finely chopped) or arugula instead of spinach. Cook kale a bit longer to soften.
- Zestier finish: Stir in a tablespoon of cream cheese to stabilize the sauce and add body if your cream is very thin.
FAQ
Can I use rotisserie chicken?
Yes.
Shred or slice rotisserie chicken and warm it in the sauce at the end. Skip the searing step and start with the garlic, broth, and cream base. It’s a great shortcut for busy nights.
What’s the best store-bought pesto for keto?
Look for pesto made with olive oil, basil, nuts, and cheese, without added sugars or seed oils.
Check the carb count per serving; many good brands list 1–2 grams net carbs per tablespoon.
Can I make this ahead?
Yes. Cook the sauce and chicken, then cool and refrigerate. Reheat gently on the stove, adding a splash of broth or cream to loosen.
Add fresh spinach and lemon just before serving for the best texture and brightness.
How can I thicken the sauce without flour or starch?
Reduce the sauce by simmering a few extra minutes, or whisk in more Parmesan or a spoonful of cream cheese. Both add body while keeping it low-carb.
What sides go well with this?
Try zucchini noodles tossed in butter, roasted broccoli, cauliflower rice, sautéed green beans, or a simple side salad with olive oil and lemon. Keep sides light to balance the richness.
Can I use half-and-half instead of heavy cream?
You can, but it’s more likely to break and won’t thicken as well.
If you use half-and-half, keep the heat low and consider adding a bit of cream cheese to stabilize the sauce.
Is this recipe spicy?
Not by default. It’s mild and creamy. Add a pinch of red pepper flakes if you want a gentle kick.
In Conclusion
Keto Creamy Pesto Chicken is simple, satisfying, and adaptable.
It turns a handful of basics into a silky, herby sauce that makes dinner feel special with hardly any effort. Keep a jar of good pesto and some cream on hand, and you can pull this off any night of the week.
