Keto Chicken and Green Beans Skillet (Quick One Pan Meal) - Simple Weeknight Dinner
Ingredients
- 1.25–1.5 pounds boneless, skinless chicken breasts or thighs (thighs stay juicier)
- 12 ounces fresh green beans, trimmed
- 2 tablespoons olive oil (plus more if needed)
- 1–2 tablespoons butter or ghee
- 4 cloves garlic, minced
- 1 teaspoon onion powder
- 1 teaspoon smoked paprika (or regular paprika)
- 1/2 teaspoon crushed red pepper flakes (optional, for heat)
- 1/2 teaspoon dried thyme or Italian seasoning
- 1/2 teaspoon kosher salt, plus more to taste
- 1/4 teaspoon black pepper
- 1 lemon (zest and juice)
- 1/3 cup chicken broth (low sodium)
- 2 tablespoons grated Parmesan (optional)
- Fresh parsley for garnish (optional)
Instructions
- Prep the chicken: Pat dry and slice into bite-size pieces or thin strips for quick cooking. Toss with salt, pepper, onion powder, paprika, and thyme.
- Blanch or quick-steam the beans (optional but recommended): Microwave green beans with a splash of water for 2 minutes, or blanch in boiling water for 2–3 minutes. Drain well. This gives you crisp-tender beans that finish perfectly in the skillet.
- Sear the chicken: Heat 1 tablespoon olive oil in a large skillet over medium-high. Add half the chicken in a single layer. Cook 3–4 minutes per side until browned and cooked through. Transfer to a plate. Repeat with another tablespoon of oil and remaining chicken.
- Build the pan base: Reduce heat to medium. Add butter or ghee to the skillet. Stir in garlic and red pepper flakes, cooking 30–45 seconds until fragrant. Scrape up browned bits with a spatula.
- Deglaze: Pour in chicken broth and simmer 1–2 minutes to reduce slightly. Add lemon zest and half the lemon juice. Taste and adjust salt.
- Add beans and finish: Toss green beans in the sauce for 2–3 minutes until coated and crisp-tender. Return chicken and any juices to the pan. Stir to combine and warm through, 1–2 minutes.
- Final touches: Squeeze in more lemon juice to taste. Sprinkle Parmesan if using. Garnish with parsley. Serve hot.

Keeping It Fresh
- Storage: Cool fully, then store in an airtight container up to 4 days in the fridge.
- Reheat: Warm gently in a skillet over medium-low with a splash of broth or water, or microwave in short bursts. Avoid overcooking to keep the chicken tender.
- Freezing: You can freeze for up to 2 months, but green beans may soften. For best texture, freeze the cooked chicken and sauce, add fresh sautéed beans when reheating.
- Meal prep tip: Portion into two or three containers with a lemon wedge.
Add cheese right before eating to keep it melty and fresh.
Why This is Good for You
- Protein-rich: Chicken delivers the protein you need to feel full and support muscle health.
- Low in carbs, big on fiber: Green beans add fiber, vitamins A, C, and K, plus a nice crunch without the carbs of starchy sides.
- Healthy fats: Olive oil and butter or ghee help with satisfaction and flavor, which is useful on a keto plan.
- Smart seasoning: Garlic, lemon, and herbs boost taste without added sugars or heavy sauces.
What Not to Do
- Don’t crowd the pan: Overcrowding steams the chicken and prevents browning. Cook in batches for a nice sear.
- Don’t skip salt: Proper seasoning makes low-carb meals shine. Taste at each step.
- Don’t overcook the beans: Mushy beans drag the dish down.
Aim for bright green and tender with a snap.
- Don’t drown it in lemon: Add lemon gradually. You want a bright finish, not a sour one.
- Don’t rely only on chicken breast: If dryness is an issue, use thighs. They’re forgiving and flavorful.
Alternatives
- Protein swaps: Turkey tenderloin, pork tenderloin strips, or shrimp (add shrimp at the end and cook 2–3 minutes until pink).
- Veggie swaps: Asparagus, broccoli florets, zucchini, or bell peppers.
Keep pieces similar in size and adjust cook times.
- Sauce twist: Stir in 2–3 tablespoons heavy cream or a spoon of cream cheese at the end for a silky, keto-friendly sauce.
- Herb and spice switch-ups: Try Cajun seasoning, lemon pepper, or a garlic-herb blend. Add a touch of cumin and coriander for a warmer profile.
- Cheese options: Parmesan, pecorino, feta crumbles, or a sprinkle of shredded mozzarella melted on top.
- Extra crunch: Toasted sliced almonds or pine nuts for texture and healthy fats.
FAQ
Can I use frozen green beans?
Yes. Thaw and pat dry first to avoid excess moisture, then sauté a minute longer to cook off water.
The texture won’t be as crisp as fresh, but it still works well.
How can I make it spicier?
Add more red pepper flakes, a pinch of cayenne, or use a spicy seasoning blend like Cajun or chipotle. Taste as you go so the heat doesn’t overwhelm the lemon and garlic.
Is this recipe dairy-free?
It can be. Use olive oil only and skip the butter and Parmesan.
The dish still tastes bright and savory thanks to garlic, broth, and lemon.
What’s the best skillet to use?
A large stainless steel or cast-iron skillet is ideal for browning. Nonstick also works, but you’ll get less color. Make sure it’s wide enough so the chicken isn’t crowded.
How do I keep the chicken juicy?
Cut even-sized pieces, get the pan hot before searing, and don’t overcook.
Pull the chicken once it’s just done, then finish everything together briefly in the sauce.
Can I make it ahead?
Yes. Cook fully, cool, and refrigerate. Reheat gently with a splash of broth.
For freshest beans, you can cook the chicken and sauce ahead, then add quickly sautéed beans when reheating.
How many carbs are in a serving?
It varies with portions and add-ins, but typically around 6–8 net carbs per serving without the Parmesan. Using precise brands and weights will give the most accurate count.
What can I serve with it?
Try cauliflower rice, mashed cauliflower, or a simple side salad with olive oil and vinegar. If not strictly keto, buttered polenta or quinoa also pair well.
Can I make it creamy without dairy?
Yes.
Add a splash of unsweetened almond milk and a teaspoon of Dijon to emulsify, or stir in a spoon of coconut cream. Season well to balance flavors.
Will lemon curdle any cream I add?
If you add heavy cream, reduce the heat and stir it in off the boil, then finish with lemon to taste. This helps prevent curdling and keeps the sauce smooth.
