There’s a moment—usually around 6:17 p.m.—when the kitchen smells like toasted pine nuts and garlic, when the cream is just beginning to bubble, and when the chicken is so tender it practically sighs as you slice it. That moment is why I created this Keto Creamy Pesto Chicken with Sun-Dried Tomatoes. It’s the dish I make when I want to feel like I’m dining at a candle-lit trattoria along the Amalfi Coast, but I’m actually standing in my slippers in a suburban kitchen while the dog watches hopefully for dropped cheese.
I first served this on a random Tuesday when both kids had orthodontist appointments, the garage door had broken for the third time that month, and I needed—needed—something that said “I have my life together.” One bite in, my teenager actually looked up from her phone and said, “Wait, this is keto?” Victory. Since then it’s become my go-to for bridal showers, meal-train drop-offs, and every single birthday request from my pesto-obsessed best friend. It feels fancy enough for company, reheats like a dream for lunch, and keeps carbs low enough that you can still have a square of dark chocolate afterwards without a twinge of guilt.
Why This Recipe Works
- One-pan wonder: From sear to sauce, everything happens in a single skillet—minimal dishes, maximum flavor.
- Silky pesto cream: A blend of basil pesto and heavy cream reduces into a glossy sauce that clings to every chicken fiber.
- Sun-dried tomato punch: Their tangy-sweet intensity balances the richness and keeps carbs in check (2 g net per serving).
- 5 g net carbs: Keto-friendly without tasting like “diet food,” so even carb-lovers devour it.
- 30-minute meal: Restaurant-quality dinner on the table faster than take-out delivery.
- Freezer-friendly: Double the batch; freeze half of the uncooked marinated chicken for a future 15-minute shortcut.
Ingredients You'll Need
Quality matters here. Because the ingredient list is short, each component shines. Look for organic chicken breasts that are plump and rosy—avoid the pale, injected ones that release watery liquid in the pan. If you can find air-chilled chicken, grab it; the flavor is cleaner and the skin (should you ever want skin-on) crisps like a dream.
For the pesto, homemade is divine but not mandatory. I keep a jar of refrigerated basil pesto from the produce section for frantic evenings; choose one whose first ingredient is basil, not canola oil. If you’re dairy-free, swap in a vegan pesto made with cashews and nutritional yeast—you’ll still get that herbaceous punch.
Sun-dried tomatoes packed in olive oil are softer and silkier than dry ones. Blot away excess oil to keep carbs accurate and prevent the sauce from breaking. If you only have dry-packed, rehydrate them for 10 minutes in warm water with a splash of vinegar to wake up their flavor.
Heavy cream reduces beautifully without curdling, but if you need a lighter version, use half-and-half mixed with 1 tsp arrowroot starch. The carbs stay negligible and the sauce stays lush. And please, grate your own Parmesan—pre-shredded cellulose-coated cheese won’t melt smoothly into the sauce.
How to Make Keto Creamy Pesto Chicken with Sun-Dried Tomatoes
Butterfly & Season
Place chicken breasts on a cutting board. Holding your knife parallel to the board, slice horizontally through the thickest part, stopping ½ inch before the opposite edge. Open like a book. This creates two thinner cutlets that cook evenly and absorb more pesto cream. Pat very dry, then season both sides generously with 1 tsp kosher salt, ½ tsp black pepper, and ½ tsp garlic powder.
Sear for Fond
Heat 2 Tbsp olive oil in a 12-inch stainless or cast-iron skillet over medium-high until shimmering. Lay chicken in; don’t crowd. Sear 3 minutes without moving—this builds the golden-brown fond that flavors the sauce. Flip, sear 2 more minutes. Chicken should be just shy of done. Transfer to a plate; tent loosely.
Aromatics & Deglaze
Lower heat to medium. Add 1 Tbsp butter and 2 minced garlic cloves; sauté 30 seconds. Pour in ¼ cup dry white wine (or chicken broth + 1 tsp lemon juice). Scrape the browned bits with a wooden spoon; reduce liquid by half, about 1 minute. Your kitchen will smell like a trattoria at this point—embrace it.
Create the Creamy Base
Stir in 1 cup heavy cream, 3 Tbsp pesto, and ¼ tsp red-pepper flakes. Bring to a gentle simmer—do not boil—and cook 2 minutes until slightly thickened. The pesto will tint the cream a delicate spring green.
Add Sun-Dried Tomatoes
Drain â…“ cup sun-dried tomatoes; pat dry and slice into thin ribbons. Stir into the sauce. Their ruby flecks look like confetti against the green cream.
Reunite Chicken & Sauce
Nestle chicken and any accumulated juices back into the skillet. Simmer 2–3 minutes until chicken reaches 165 °F and sauce coats the back of a spoon. If too thick, loosen with a splash of broth; taste and adjust salt.
Finish with Cheese & Basil
Off heat, stir in ÂĽ cup freshly grated Parmesan and a handful of torn basil leaves. The residual warmth melts the cheese into velvet. Serve hot, spooning extra sauce over each plate.
Expert Tips
Temperature Trick
Pull chicken at 160 °F; carry-over heat will finish it to juicy 165 °F while it rests in the sauce.
Sauce Insurance
If sauce breaks, whisk in 1 tsp cold cream over low heat—it’ll re-emulsify instantly.
Make-Ahead Marinade
Combine 2 Tbsp pesto + 2 Tbsp olive oil; marinate chicken up to 24 hr—flavor skyrockets.
Double Duty
Double sauce, toss with zucchini noodles next day; lunch is done in 90 seconds.
Variations to Try
- Dairy-Free: Use coconut cream + nutritional-yeast pesto; swap Parmesan for 2 Tbsp almond flour for body.
- Seafood Spin: Swap chicken for shrimp; cook 1 min per side, proceed identically—dinner in 15 minutes flat.
- Spicy Tuscan: Add ½ cup chopped kale and ¼ tsp cayenne; the kale wilts in the cream and soaks up flavor.
- Mushroom Lover: Sauté 8 oz sliced cremini after searing chicken; they’ll soak up pesto cream like savory sponges.
Storage Tips
Refrigerate: Cool completely, transfer to an airtight container, and refrigerate up to 4 days. The flavors meld beautifully, making leftovers something to celebrate.
Freeze: Place chicken and sauce in a freezer-safe bag; lay flat to freeze up to 3 months. Thaw overnight in fridge, then warm gently with a splash of broth.
Reheat: Warm in a covered skillet over low with 2 Tbsp broth, 5 minutes or until 165 °F. Microwave works, but skillet keeps the chicken supple.
