When the craving for something bold, creamy, and keto-friendly hits at the end of a long day, this Spicy Keto Chicken and Cashew Curry is the recipe I turn to again and again. I first threw it together on a rainy Tuesday when the fridge was nearly bare—just chicken thighs, a handful of cashews, and the dregs of a jar of red curry paste. What emerged from the skillet 30 minutes later was so lusciously spicy, so rich with nutty coconut goodness, that my husband and I found ourselves standing at the stove, “taste-testing” until half the batch had disappeared before dinner officially started.

Since then, it’s become our Friday-night ritual: light candles, queue up a playlist of lo-fi beats, and let the aromas of ginger, garlic, chili, and toasted cashews weave through the house like an invitation to relax. Whether you’re feeding a crowd or simply treating yourself to a meal-prep victory, this curry delivers restaurant-level flavor without the carb load. At roughly 6 g net carbs per serving, it keeps you in ketosis while still feeling downright indulgent. Ready to join me at the stove?

Why This Recipe Works

Keto-Approved Creaminess: Cashew butter and coconut milk replace flour-thickened sauces, slashing carbs while keeping every spoonful silky.
One-Pan Ease: From browning the chicken to simmering the sauce, everything happens in a single skillet—minimal dishes, maximum flavor.
Customizable Heat: Dial the chili up or down without throwing off the balance; the curry still tastes complex thanks to aromatics and toasted spices.
Budget-Friendly Protein: Boneless, skinless chicken thighs stay juicy and cost less than breast meat, making this a weekly staple.
Meal-Prep Star: Flavors deepen overnight, so Sunday’s batch becomes even better Monday lunches.
Veggie-Loaded: A full cup of diced zucchini and bell pepper sneaks in nutrients without piling on carbs.
Restaurant Vibes at Home: Toasting whole cashews and blooming spices in ghee unlocks layers you thought only take-out could deliver.

Ingredients You'll Need

Great curry starts with great building blocks. Below is everything you’ll need, plus a few smart substitutions in case your pantry is missing something mid-week.

Chicken: 1 ½ lb (680 g) boneless, skinless chicken thighs, trimmed of excess fat and cut into 1-inch pieces. Thighs stay succulent even if you accidentally overcook them a touch; if you only have breast on hand, reduce simmering time by 3 minutes to avoid dryness.

Whole Cashews: ¾ cup, divided. Half will be toasted for a nutty crunch on top, the rest blends into the sauce for natural thickening power without flour or cornstarch.

Cashew Butter: 3 tablespoons. Choose a brand with no added sugar; the only ingredient should be cashews (and maybe a pinch of salt). If you’re allergic, almond butter works, though the flavor is slightly less sweet.

Full-Fat Coconut Milk: One 13.5-oz can. Do not substitute “lite” varieties; you need the richness to carry the spices. Shake well before opening.

Red Curry Paste: 2 tablespoons. Check labels—some brands sneak in sugar. Thai Kitchen and Mekhala are both keto-friendly and widely available.

Fresh Aromatics: 1 medium shallot, 3 cloves garlic, and a 1-inch knob of ginger. Fresh really does make a difference; pre-mined jars often taste flat.

Low-Carb Veggies: ½ cup diced zucchini and ½ cup diced red bell pepper add color and micronutrients for minimal carbs. Feel free to swap in mushrooms or cauliflower florets.

Spice Squad: 1 teaspoon ground turmeric for earthy color, ½ teaspoon smoked paprika for subtle warmth, and ¼–½ teaspoon cayenne if you like it fiery.

Ghee or Coconut Oil: 2 tablespoons for high-heat searing and that authentic nutty backdrop.

Lime & Cilantro: A squeeze of fresh lime just before serving brightens all the rich elements, while cilantro adds a pop of herbal freshness. If you’re genetically predisposed to soap-flavored cilantro, swap in Thai basil.

Salt & Pepper: Start conservatively—curry paste and cashew butter carry sodium; you can always adjust at the end.

How to Make Spicy Keto Chicken and Cashew Curry for a Nutty and Spicy Dinner

Toast the Cashews

Place a large, dry skillet over medium heat. Add 6 tablespoons of the whole cashews and shake the pan frequently until they’re golden and fragrant, 3–4 minutes. Transfer to a small bowl; you’ll use these for garnish later. Resist snacking—they’re dangerously addictive.

Sear the Chicken

Return the same skillet to medium-high heat and add ghee. Once shimmering, pat chicken pieces very dry (moisture = steam = no browning) and lay them in a single, uncrowded layer. Sear 3 minutes without moving; flip and brown the second side another 2 minutes. You’re not cooking through—just building fond, those caramelized bits that equal pure flavor.

Bloom Aromatics & Spices

Push chicken to the perimeter, lower heat to medium, and add minced shallot to the center. Sauté 2 minutes until translucent, then stir in garlic and ginger for 30 seconds—until the smell punches the air. Sprinkle turmeric and paprika over everything; cook 45 seconds, stirring, so the raw edge disappears and the oil turns sunshine-yellow.

Create the Curry Base

Scrape in red curry paste; stir to coat everything and toast the spices within the paste, 1 minute. Pour in half the coconut milk and whisk (a silicone-coated whisk saves your pan) until the mixture is smooth and brick-red. Add remaining coconut milk, cashew butter, and ½ cup water; whisk until silky.

Simmer to Perfection

Return seared chicken (and any resting juices) to the pan along with zucchini and bell pepper. Bring to a gentle bubble, cover, and simmer 10 minutes, stirring once midway. Uncover, taste, and add cayenne for extra heat or a pinch of salt if needed. Cook 5 minutes more, until chicken hits 165 °F and veggies are tender-crisp.

Blend a Portion for Body

Optional but restaurant-level: ladle one cup of the sauce (avoid big veggie chunks) into a blender, add the reserved untoasted cashews, and blitz until ultra-smooth. Stir back into the skillet for velvet-rich texture without extra carbs.

Finish & Serve

Remove from heat, squeeze in the juice of half a lime, and scatter cilantro leaves and those gorgeous toasted cashews on top. Spoon over cauliflower rice or shirataki noodles and pass extra lime wedges at the table.

Expert Tips

Double the Spice Base

Make a triple batch of the curry paste + spice mixture and freeze in ice-cube trays. On busy weeks, just sear protein, drop in a cube, add coconut milk, and dinner’s done.

Control the Heat Early

Taste your curry paste out of the jar; brands vary wildly. Start with 1 tablespoon if you’re heat-sensitive and add more in the final simmer.

Make-Ahead Magic

Curry thickens as it cools; thin leftovers with a splash of stock when reheating. Flavors meld overnight, so it’s perfect for Sunday prep.

Deglaze Like a Pro

If brown bits threaten to burn, splash 2 tablespoons of water into the skillet and scrape with a wooden spoon before adding aromatics—free flavor!

Knife Shortcut

Partially freeze chicken thighs for 20 minutes; they’ll slice into even cubes in half the time.

Macro Boost

Need more fat for your keto ratio? Stir an extra tablespoon of MCT oil into individual portions just before serving.

Variations to Try

Prawn & Cashew Swap: Replace chicken with peeled shrimp; simmer only 3 minutes to avoid rubbery texture.
Vegetarian Keto: Use firm tofu or paneer. Brown gently, then proceed with the same sauce.
Green Curry Spin: Sub green curry paste and add Thai basil plus 1 teaspoon lime zest for a brighter profile.
Extra-Creamy: Whisk 2 tablespoons cream cheese into the sauce at the end for Philadelphia-style richness.
Nut-Free: Swap cashews with pumpkin-seed butter and toasted pepitas; macros stay keto, allergy risk drops.

Storage Tips

Refrigerator: Cool curry completely, then spoon into airtight glass containers. It keeps up to 4 days, though the cashews will soften slightly. Reheat gently with a splash of broth or coconut milk to loosen.

Freezer: Portion into silicone muffin trays, freeze until solid, then pop out and store in a zip bag up to 3 months. Thaw overnight in the fridge and warm slowly—high heat can cause cashew-based sauces to separate.

Meal-Prep Bowls: Layer cauliflower rice on one side, curry on the other. Top with fresh herbs just before microwaving so they stay vibrant.
