Ingredients
Method
- Season the chicken: Pat chicken dry. Season both sides with salt, pepper, Italian seasoning, and smoked paprika.
- Sear the chicken: Heat 1 tablespoon olive oil and the butter in a large skillet over medium-high. Add chicken and sear 4–5 minutes per side until golden. Transfer to a plate; tent with foil.
- Sauté the aromatics: Lower heat to medium. Add remaining 1 tablespoon olive oil. Stir in garlic; cook 30 seconds until fragrant, not browned.
- Build the sauce base: Stir in tomato paste and cook 1 minute to caramelize. Whisk in chicken broth, scraping up browned bits.
- Make it creamy: Reduce heat to medium-low. Pour in heavy cream and whisk until smooth. Add Parmesan and red pepper flakes. Simmer gently 2–3 minutes until slightly thickened.
- Add tomatoes and basil: Stir in cherry tomatoes and most of the basil. Simmer 1 minute to soften tomatoes without breaking them down.
- Finish the chicken: Return chicken and any juices to the skillet. Spoon sauce over the top. Simmer 3–5 minutes, or until chicken reaches 165°F internally and sauce coats the back of a spoon. Adjust salt and pepper. Squeeze a little lemon if you like.
- Serve: Top with remaining basil. Serve over zucchini noodles, cauliflower rice, or sautéed spinach, with extra sauce spooned on top.
What Makes This Recipe So Good

Storage Instructions

Why This Is Good for You
- Keto-friendly macros: Low in carbs and high in fat, this dish helps keep you in ketosis while feeling satisfied.
- Protein-rich: Chicken provides steady energy and supports muscle maintenance.
- Tomato antioxidants: Tomatoes and tomato paste add lycopene and vitamin C.
- Fresh herbs: Basil brings antioxidants and bright flavor with minimal carbs.
What Not to Do
- Don’t boil the cream hard: A rolling boil can cause the sauce to split. Keep the heat gentle.
- Don’t skip seasoning the chicken: Seasoning before searing makes a big difference in flavor.
- Don’t crowd the pan: If your skillet is small, sear in batches so you get good browning, not steaming.
- Don’t add watery tomatoes: If using canned, drain well to avoid a thin sauce.
- Don’t overcook: Dry chicken is hard to rescue. Use a thermometer for accuracy.
Recipe Variations
- Sun-dried tomato spin: Add 2 tablespoons chopped sun-dried tomatoes in oil to the sauce for concentrated flavor.
- Thighs instead of breasts: Use boneless thighs for extra juiciness.
Adjust cook time slightly; they’re forgiving.
- Garlic-basil butter finish: Stir in 1 tablespoon butter at the end for extra gloss and richness.
- Dairy-light option: Swap half the cream for full-fat coconut milk. Flavor changes slightly but stays creamy.
- Veggie boost: Add a handful of baby spinach in the last minute to wilt into the sauce.
- Extra heat: Use more red pepper flakes or a pinch of cayenne for a gentle kick.
FAQ
Can I make this with bone-in chicken?
Yes, but sear the pieces, then finish them in the oven at 375°F until they reach 165°F. Build the sauce in the same skillet and add the cooked chicken back in to coat.
Is tomato paste keto?
Tomato paste is more concentrated but used in small amounts here.
It adds rich flavor with minimal carbs per serving, keeping the dish keto-friendly.
How can I thicken the sauce without flour?
Simmer gently to reduce, and rely on cream and Parmesan to thicken. If needed, add a little more Parmesan or let it cook an extra minute or two.
What sides go best with this?
Zucchini noodles, cauliflower rice, roasted asparagus, or sautéed garlic green beans all pair well and keep carbs low.
Can I use dried basil instead of fresh?
You can, but use less. Start with 1 to 1.5 teaspoons dried basil added earlier in the simmer, then finish with a small amount of fresh if you have it.
How do I prevent the sauce from curdling?
Keep the heat moderate, avoid boiling, and add the cream after deglazing with broth.
Whisk in Parmesan off a hard boil to keep it smooth.
Can I make it dairy-free?
Use full-fat coconut milk instead of cream and skip the Parmesan, or use a dairy-free parmesan-style topping. Flavor will be slightly different but still delicious.
What if I don’t have tomato paste?
Reduce 1/2 cup crushed tomatoes in the pan until thick and jammy, then continue with the recipe. Flavor will be a bit lighter but still good.
How spicy is this?
It’s mild as written.
Red pepper flakes add a gentle warmth. Adjust to taste or omit entirely.
Can I meal prep this?
Absolutely. Cook as directed, cool, and portion with a keto side.
Reheat gently during the week for quick meals.
