Deviled chicken earns its name honestly — a punchy marinade of mustard, paleo mayo, hot sauce and garlic turns plain chicken breasts into something with real fire. A toasted almond-and-pecan crumb topping finishes the job in a hot oven. Zesty, crunchy, weeknight-easy.
Pro Tips
- Marinate the chicken at least 30 minutes and up to 3 hours — the mustard and hot sauce soak in, and the mayo keeps the lean breasts moist in the oven.
- Toast the almond flour and chopped nuts in coconut oil for 3-5 minutes, stirring often — the crumb topping goes from golden to burnt fast, so watch closely.
- Let excess marinade drip off the chicken as it goes onto the greased rack; pooled marinade steams the coating instead of crisping it.
- Press the toasted crumbs gently onto each breast so they adhere through the bake.
- Bake at 450°F for 20-25 minutes until an instant-read thermometer reads 160°F, then rest the chicken 5-10 minutes before serving.
Frequently Asked Questions
Why is it called deviled chicken?
The classic deviled treatment — mustard and hot sauce — gives the marinade its lively, peppery kick. Paleo mayo rounds it out and keeps the chicken moist.
Can I marinate it overnight?
The recipe caps the marinade at 3 hours. Beyond that the mustard and acid start to change the chicken's texture, so stick to the window.
Pecans or almonds for the topping?
Either — finely chopped pecans toast up richer, almonds a little lighter. Both make an excellent crisp crust over the tender meat.
How do I know the chicken is done?
An instant-read thermometer in the thickest part should register 160°F. The 5-10 minute rest finishes the cooking and settles the juices.

Ingredients
Method
- 1.
- Adjust an oven rack to the upper-middle position and preheat the oven to 450∘F (230∘C).
- In a large bowl, combine the Mustard, Mayonnaise, Hot Sauce, lemon juice, garlic, thyme, pepper (approx. 0.25 oz/7 g), and sea salt (approx. 0.16 oz/4.5 g).
- Stir in the chicken, making sure it's well-coated.
- Cover and refrigerate for at least 30 minutes or up to 3 hours.
- 2.
- Meanwhile, prepare the topping. Melt the coconut oil (0.5 oz/14 g) in a 12-inch (30-cm) nonstick skillet over medium heat.
- In a small bowl, combine the almond flour, chopped nuts, sea salt (0.05 oz/1.5 g), and pepper (0.02 oz/0.6 g).
- Add this mixture to the skillet and toast, stirring often, until fragrant and lightly golden, about 3 to 5 minutes. Watch closely to prevent burning.
- Remove from heat.
- 3.
- Line a rimmed baking sheet with aluminum foil and place a wire rack on top.
- Grease the rack with a small amount of coconut oil.
- Transfer the marinated chicken to the prepared wire rack, allowing excess marinade to drip off.
- 4.
- Sprinkle the toasted paleo crumbs evenly over the top of the chicken, pressing gently to help them adhere.
- 5.
- Bake until the chicken is cooked through and an instant-read thermometer registers 160∘F (71∘C), about 20 to 25 minutes.
- Let the chicken rest for 5 to 10 minutes before serving.
