Serve it with a simple side and you’ve got a complete dinner that feels restaurant-worthy yet totally doable on a Tuesday.
Ingredients
Method
- Prep the chicken: Pat chicken dry. Slice thick breasts horizontally to make thinner cutlets for quicker, even cooking. Season both sides with salt, pepper, and a light sprinkle of garlic powder.
- Brown the chicken: Heat olive oil and butter in a large skillet over medium-high heat. Sear chicken 3–4 minutes per side until golden. Remove to a plate; it will finish cooking in the sauce.
- Deglaze and build flavor: Lower heat to medium. Pour in chicken broth and scrape up browned bits with a wooden spoon. Reduce by about half, 2–3 minutes.
- Add cream and pesto: Stir in heavy cream and pesto. Simmer gently for 2–3 minutes until slightly thickened. Taste and adjust salt and pepper.
- Finish the chicken: Return chicken (and any juices) to the pan. Simmer 4–6 minutes, spooning sauce over, until chicken is cooked through (internal temp 165°F/74°C). If sauce is too thick, splash in a bit more broth or cream.
- Stir in extras: Fold in Parmesan and spinach until wilted, 30–60 seconds. Add cherry tomatoes for brightness, if using. Finish with lemon zest, a squeeze of lemon juice, and a pinch of red pepper flakes.
- Serve: Spoon plenty of sauce over each piece. Garnish with fresh basil and extra Parmesan. Pair with sautéed zucchini, roasted broccoli, or mashed cauliflower.

Keeping It Fresh
Store leftovers in an airtight container in the fridge for up to 3 days. The sauce thickens as it chills, so add a splash of broth or cream when reheating to loosen it up.
Reheat gently on the stove over low heat or in the microwave at 50% power to keep the chicken tender.
If you plan to meal-prep, keep the tomatoes and basil separate and add them just before serving for the best texture and color. This dish also freezes fairly well for up to 2 months, but cream sauces can separate a bit—reheat slowly and whisk to bring it back together.
Why This is Good for You
- Protein-rich: Chicken provides the protein you need to feel full and support muscle recovery.
- Healthy fats: Olive oil, nuts in the pesto, and a bit of cream add satisfying fats that fit a keto lifestyle.
- Low-carb: No pasta or starchy fillers—just flavorful sauce, lean protein, and optional low-carb veggies.
- Micronutrients: Spinach and basil bring vitamins A and K, while lemon adds brightness without carbs.
Pitfalls to Watch Out For
- Overcooking chicken: It turns dry fast. Sear to color, then finish gently in the sauce and pull it as soon as it hits 165°F.
- Boiling the cream: High heat can cause splitting.
Keep it to a gentle simmer.
- Salty pesto: Store-bought pesto can be salty. Taste before adding extra salt, especially after Parmesan goes in.
- Watery sauce: If you add spinach straight from washing, pat it dry. Excess water will thin the sauce.
Variations You Can Try
- Chicken thighs: Juicier and hard to overcook.
Sear skinless, boneless thighs and proceed as directed.
- Dairy-light option: Swap half the cream for unsweetened almond milk and add 2–3 ounces of cream cheese to keep it silky.
- Nut-free pesto: Use pumpkin seeds or sunflower seeds instead of pine nuts, or buy a nut-free pesto.
- Extra veggies: Add sautéed mushrooms, zucchini ribbons, or steamed asparagus tips for volume without carbs.
- Spicy kick: Stir in Calabrian chili paste or more red pepper flakes for heat.
- Herb twist: Mix pesto with a spoonful of pesto rosso (sun-dried tomato pesto) for a deeper, slightly sweet edge.
FAQ
Can I use rotisserie chicken?
Yes. Shred or slice cooked rotisserie chicken and warm it gently in the sauce for 2–3 minutes. Skip the searing step and start by making the sauce, then add the chicken at the end.
What can I use instead of heavy cream?
For keto, try a blend of unsweetened almond milk and cream cheese.
Coconut cream also works, but it adds a coconut flavor that can compete with the pesto.
Is store-bought pesto okay for keto?
Absolutely, just read the label. Choose a brand with olive oil, nuts, basil, and minimal fillers or added sugars. Some brands use cheaper oils or add potato flakes—skip those.
How do I thicken the sauce without flour?
Reduce it a bit longer over gentle heat.
Parmesan also helps thicken. If needed, whisk in a small amount of cream cheese until smooth.
What sides go well with this?
Try sautéed zucchini, roasted asparagus, green beans with butter and lemon, or creamy mashed cauliflower. A simple arugula salad with olive oil and lemon is great, too.
Can I make it ahead?
Yes.
Cook fully, cool, and refrigerate. Reheat slowly with a splash of broth or cream. Add fresh basil and tomatoes right before serving to keep it bright.
How do I keep chicken breasts from drying out?
Slice them into thinner cutlets for fast, even cooking.
Sear for color, then finish gently in the sauce and pull them once they reach temperature. Resting a few minutes also helps retain juices.
Could I use turkey or pork instead?
Yes. Turkey cutlets or thin pork chops work well.
Adjust cooking time so the meat cooks through without drying out, and keep the sauce at a gentle simmer.
