This dish has since become my go-to for everything from impromptu dinner parties to Sunday-meal-prep containers. It’s luxe enough to serve over cauliflower mash when friends come over, yet fast enough for a 30-minute weeknight rescue. The sauce is silky, tangy, and garlicky; the chicken stays juicy thanks to a quick golden sear; and the artichokes plus spinach bring fiber, color, and that “I’m eating something green” smugness. Best of all, every lustrous bite is keto-friendly, gluten-free, and clocks in at roughly 5 g net carbs—so you can sop up extra sauce without a single twinge of guilt.

Ingredients You'll Need

Great sauces start with great building blocks. Below is a quick field guide to each component so you know what to look for at the store and how to swap if your pantry (or dietary needs) demand it.

Chicken

I prefer boneless, skinless chicken breasts sliced horizontally into cutlets; they cook evenly and soak up sauce quickly. Thighs work too—just trim excess fat and add two extra minutes per side. Organic, air-chilled chicken releases less moisture, giving you a better golden crust.

Artichoke Hearts

Water-packed quarters save prep time, but frozen or fresh baby artichokes (steamed and halved) lend a nuttier bite. Pat them dry so they sear rather than steam.

Spinach

Baby spinach wilts in seconds and keeps the dish vibrant. If you only have mature spinach, remove the thicker stems. Kale or Swiss chard are sturdy substitutes—massage with ½ tsp salt first to tenderize.

Heavy Cream

Go for 36 % fat. Lower-fat creams can split when boiled. For a dairy-light version, substitute ¾ cup canned coconut milk plus 2 tbsp cream cheese for stability.

Lemon

Both juice and zest are non-negotiable. Zest carries the aromatic oils; juice brightens the finish. Meyer lemons add subtle sweetness if you’re serving non-keto guests.

Garlic & Shallots

Shallots give a gentler allium note than yellow onions. Roasted garlic cloves (if you have them) add caramel depth.

Parmesan

Buy a block and grate fresh; cellulose in pre-shredded brands can make sauce grainy. Pecorino Romano or Grana Padano are equally tasty.

Seasonings

A simple mix of sea salt, cracked black pepper, and Italian herb blend keeps the profile bright. Add a pinch of red-pepper flakes for subtle heat that plays off the lemon.

Oil & Butter

Avocado oil for searing (high smoke point) plus grass-fed butter for finishing round out flavor.

How to Make Keto Creamy Lemon Chicken with Artichokes and Spinach

Prep & Pound

Place chicken between two sheets of parchment and gently pound to ½-inch thickness. This guarantees even cooking and tender texture. Season both sides with 1 tsp salt, ½ tsp pepper, and ½ tsp Italian herb blend.

Sear for Fond

Heat 2 tbsp avocado oil in a 12-inch stainless or cast-iron skillet over medium-high until shimmering. Add chicken; cook 3½ minutes per side until deeply golden. Transfer to a plate (don’t worry if they’re not fully cooked—they’ll finish in the sauce). Leave the browned bits (fond) in the pan; that’s pure flavor.

Aromatics First

Lower heat to medium. Add 1 tbsp butter plus minced shallots; sauté 2 minutes until translucent. Stir in 3 cloves minced garlic for 30 seconds—just until fragrant—to avoid bitterness.

Deglaze & Reduce

Pour in ⅓ cup dry white wine (or chicken broth) and scrape the pan with a wooden spoon. Let it bubble away by half, about 2 minutes. This lifts the caramelized bits and forms the sauce base.

Create the Creamy Emulsion

Reduce heat to low. Stir in 1¼ cups heavy cream, 1 tsp lemon zest, and 2 tsp fresh thyme. Simmer gently (do NOT boil) for 4 minutes until slightly thickened. The sauce should coat the back of a spoon.

Cheese & Chicken Return

Whisk in ½ cup freshly grated Parmesan until melted. Nestle chicken (and any resting juices) back into the skillet. Cover and simmer 3 minutes to finish cooking the meat to 165 °F internal temperature.

Veggie Finish

Fold in quartered artichoke hearts and 2 big handfuls of spinach. Cook 1 minute until spinach wilts and artichokes are heated through. Taste and adjust with salt, pepper, or a squeeze of lemon.

Serve & Garnish

Spoon over cauliflower rice, zucchini noodles, or shirataki fettuccine. Drizzle with remaining pan sauce and sprinkle chopped parsley or extra Parmesan. Serve immediately while the sauce is glossy.

Expert Tips

Control the Heat

After adding cream, keep the liquid at a bare simmer. Boiling causes the fat to separate and you’ll end up with an oily puddle instead of velvet.

Thicken Without Flour

Let the sauce reduce naturally. If you’re rushed, sprinkle ⅛ tsp xanthan gum while whisking for instantaneous body.

Double the Sauce

Trust me—people fight over it. Double the cream base and freeze half for quick weeknight meals later.

Brine for Juiciness

If you have 15 extra minutes, soak the chicken in 2 cups water + 1 tbsp salt + 1 tbsp apple cider vinegar for unbeatable moisture.

Lemon Last

Add a final whisper of zest right before serving. Heat dulls citrus; last-minute zest keeps the sauce vibrant.

Check Doneness

Use an instant-read thermometer. Remove chicken at 162 °F; carry-over heat will take it to the safe 165 °F without dryness.

Variations to Try

1Mushroom Lovers: Add 8 oz sliced cremini after searing chicken; cook until edges caramelize, then proceed with the sauce.
2Caprese Style: Swap spinach for cherry tomatoes and fresh basil; finish with mozzarella pearls under the broiler for 2 minutes.
3Dairy-Free Keto: Replace cream with full-fat coconut milk and use 2 tbsp nutritional yeast instead of Parmesan.
4Seafood Spin: Substitute scallops or shrimp for chicken; sear 1 minute per side, remove, then add back during the final 2 minutes.
5Green Boost: Stir in ½ cup steamed broccoli florets or zucchini ribbons to sneak in extra veggies without raising carbs.

Storage Tips

Refrigerator

Cool completely, transfer to an airtight container, and refrigerate up to 4 days. Store sauce-covered to prevent chicken from drying.

Freezer

Place in freezer-safe bags in flat portions for up to 3 months. Thaw overnight in the fridge, then reheat gently with a splash of broth.

Frequently Asked Questions

You can, but the sauce will be thinner and can curdle. If you must, whisk 1 tsp arrowroot or xanthan gum and avoid boiling.

A dry white such Sauvignon Blanc or Pinot Grigio typically has 2-3 g carbs per 5 oz. The alcohol cooks off, leaving only 0.3 g in the entire sauce.

Whisk 1 tbsp cooled sauce into 2 tbsp cream cheese, then whisk the slurry back into the pan over low heat. It should re-emulsify.

Almost—omit Parmesan and wine, use coconut milk and chicken broth, and choose clarified butter (ghee).

Warm covered in a non-stick skillet over medium-low with 2 tbsp broth until 140 °F, about 6 minutes, stirring gently.

Yes. Use sauté function for steps 1-4, add cream and cheese, then pressure cook on HIGH for 4 minutes with quick release. Stir in veggies last to prevent mushiness.
