Keto Recipes Easy: Creamy Pesto Chicken Skillet

• One skillet handles browning, sauce building, and the final simmer, so there is less cleanup and no separate casserole dish to manage after dinner.
• Chicken thighs bring enough richness to stand up to cream and pesto, while spinach adds bulk that softens quickly into the sauce without a long vegetable-cooking step.
• The method uses visual cues throughout: browned chicken, a gently bubbling sauce, wilted spinach, and a thermometer reading of 165°F at the chicken’s center before serving.

• 1 1/2 pounds boneless, skinless chicken thighs, cut into chunks (680 g)
• 1 tablespoon olive oil (14 g)
• 1 teaspoon kosher salt (6 g)
• 1/2 teaspoon black pepper (1 g)
• 3 garlic cloves, finely grated (9 g)
• 1/2 cup heavy cream (120 g)
• 1/3 cup basil pesto (80 g)
• 1/2 cup finely grated Parmesan cheese (50 g)
• 5 ounces baby spinach, about 5 packed cups (140 g)
• 1 tablespoon fresh lemon juice (15 g)
• 1/4 teaspoon red pepper flakes (0.5 g)

Ingredient notes

• Boneless, skinless chicken thighs stay tender through the brief sauce simmer and bring more richness than breast meat. Cut larger pieces into even chunks so the pan browns them at a similar pace, rather than leaving some pieces pale while others overcook.
• Use refrigerated basil pesto with a flavor you already enjoy, because it carries most of the herb and garlic character here. Check the jar’s texture before measuring; a very thick pesto may need an extra spoonful of cream to loosen the sauce.
• Heavy cream gives the sauce enough body to coat the chicken without flour or starch. Half-and-half is a trade-off: it makes a thinner sauce that may separate more readily when boiled hard.
• Finely grate Parmesan from a wedge if possible, since finely grated cheese melts into the cream more smoothly than coarse shreds. Add it over low heat and stir steadily, keeping the sauce below a vigorous boil.
• Baby spinach is convenient because it wilts quickly and needs no chopping beyond removing any tough stems. Regular spinach works when roughly chopped first, but add it in two additions so it can settle into the pan.
• Fresh lemon juice cuts through the creamy pesto base at the end. Start with the listed amount, taste after the chicken rests briefly, and add a little more only if the sauce needs a brighter edge.

1. 1Prep the pan

   Pat the chicken dry, then cut it into evenly sized pieces so they cook at the same rate. Measure the pesto, cream, Parmesan, and seasonings before heating the skillet. Keep the spinach and lemon beside the stove; both go in near the end and move quickly once the sauce is hot.

2. 2Brown the chicken

   Heat olive oil in a large skillet over medium-high heat. Season the chicken with salt and pepper, then arrange it in one layer with space between pieces. Cook without moving it for several minutes, then turn and brown the second side. Work in batches if the skillet is crowded.

   

3. 3Soften the garlic

   Lower the heat to medium after the chicken has color. Add the grated garlic to the open spots in the pan and stir for about 30 seconds, just until fragrant. Do not let it darken; garlic can turn sharp when it catches on the skillet’s hot surface.

4. 4Build the sauce

   Pour in the cream and scrape the browned bits from the skillet with a wooden spoon. Stir in the pesto and let the mixture reach a gentle bubble. Add Parmesan gradually, stirring between additions, until the sauce looks smooth and lightly thickened around the chicken.

   

5. 5Wilt and finish

   Add spinach by handfuls, turning it through the sauce as it collapses. Sprinkle in red pepper flakes, then simmer until the chicken reaches 165°F in the center. Turn off the heat, add lemon juice, and rest the skillet for two minutes so the sauce settles around the vegetables.

6. 6Portion with intention

   Taste the sauce and adjust with pepper, lemon, or a small pinch of salt if needed. Spoon chicken and spinach into shallow bowls, making sure each portion gets sauce. For planned lunches, divide the skillet into containers after it cools briefly instead of leaving portions in the hot pan.

• Use a wide skillet, ideally 12 inches, so the chicken has room to brown instead of releasing liquid and steaming. If your pan is smaller, brown in two batches and return all the chicken before adding cream.
• Keep the cream at a gentle simmer after pesto and Parmesan go in. Hard boiling can make the sauce look greasy or grainy, especially if the skillet runs hot around its edges.
• If the sauce seems loose after the spinach wilts, simmer it uncovered for one or two additional minutes. If it becomes too thick, stir in cream one tablespoon at a time until it coats a spoon.
• Take the chicken temperature in the thickest piece, avoiding direct contact with the skillet. Resting the pan off heat for two minutes also gives the sauce time to thicken slightly before portioning.

Serve the skillet over cauliflower rice, alongside roasted broccoli, or with a crunchy romaine salad dressed simply with olive oil and lemon. The sauce also works as a spoonable topping for sautéed green beans or asparagus. Keep the side lightly seasoned at first, since pesto and Parmesan already bring salt. For a larger dinner table, add a platter of roasted mushrooms; their browned edges suit the creamy, herbal sauce without competing for attention.
