Spiced Grilled Chicken with Cilantro Lime Butter

The rodeo is back. Houston Livestock Show and Rodeo, year four of Bobby Tran's attendance and year two of Bobby Tran's competition. This year I'm entered in the Pearland Throwdown again (May) and the Bayou City BBQ Festival (April) and I'm back on Hector's team for the rodeo Cook-Off (March). Three competitions in three months. Ambitious. Maybe too ambitious for a man with a bad knee and a full-time job. But ambition is what keeps me moving, and moving is what keeps the knee from stiffening, so it's a virtuous cycle of stubbornness. Hector and I spent Saturday prepping for the rodeo Cook-Off. The team is the same: Hector, me, his brother-in-law Julio, and a guy named Marcus who works for Hector's catering company and can smoke a pork shoulder in his sleep. We're entering three categories this year: brisket (my domain), pork ribs (Hector's), and chicken (Marcus's). My brisket plan is the same as last year: fish sauce marinade, post oak with cherry, the fusion rub. But I'm adding one new element — a finishing butter. I'm making a compound butter with lemongrass, ginger, garlic, and fish sauce, and I'm going to brush it on the brisket in the last thirty minutes of the cook. The butter will melt into the bark and add a layer of richness that straight seasoning can't achieve. Tested it on a practice cook Sunday. The finishing butter was a revelation. The bark glistened. The flavor had a richness, a roundness, that the marinade alone doesn't provide. The butter bridges the gap between Vietnamese seasoning and Texas fat content. It's the missing piece. Emma tasted the practice slice and said, "This is different. What did you change?" I told her about the butter. She said, "That's genius." Then she said, "Can I try making a brown butter version?" She's already iterating on my innovation. She's already ahead of me. Ma tasted it and said, "More lemongrass." Always more lemongrass. I added more lemongrass to the next batch. She was right. The competitions are coming. The knee is holding. The butter is perfect. Let's go.

After that Sunday practice cook, I couldn’t stop thinking about what a compound butter does to a piece of protein in those final minutes of heat — the way it melts into the bark, adds fat, adds fragrance, rounds out every sharp edge of spice. The brisket version is locked in for competition, but it got me experimenting with the same finishing technique on chicken, which is how I landed on this recipe. If you’ve never brushed a compound butter onto grilled chicken in the last few minutes of the cook, you’re missing the whole point — and Ma, if you’re reading this, yes, I know: more lemongrass.

Prep Time: 20 min | Cook Time: 25 min | Total Time: 45 min | Servings: 4

Ingredients

4 bone-in, skin-on chicken thighs (about 2 1/2 lbs total)
1 tbsp smoked paprika
1 tsp ground cumin
1 tsp garlic powder
1/2 tsp onion powder
1/2 tsp cayenne pepper
1/2 tsp kosher salt
1/4 tsp black pepper
1 tbsp olive oil
Cilantro Lime Compound Butter:
4 tbsp unsalted butter, softened to room temperature
2 tbsp fresh cilantro, finely chopped
1 tsp lime zest
1 tbsp fresh lime juice
1 clove garlic, minced
1/4 tsp kosher salt
Pinch of cayenne

Instructions

Make the compound butter. In a small bowl, combine the softened butter, cilantro, lime zest, lime juice, minced garlic, salt, and cayenne. Mix thoroughly until fully incorporated. Spoon onto a sheet of plastic wrap, roll into a log shape, and refrigerate for at least 20 minutes until firm. Slice into rounds before using.
Mix the spice rub. Combine smoked paprika, cumin, garlic powder, onion powder, cayenne, salt, and black pepper in a small bowl. Pat chicken thighs completely dry with paper towels, brush lightly with olive oil, then coat all sides generously with the spice rub. Press the rub in so it adheres.
Preheat the grill. Heat a gas or charcoal grill to medium-high (about 400°F). Oil the grates. If using charcoal, set up a two-zone fire so you have direct and indirect heat available.
Grill the chicken. Place thighs skin-side down over direct heat. Grill 5–6 minutes until the skin is deeply caramelized and releases easily. Flip and move to indirect heat if using charcoal, or reduce a gas burner to medium. Cover and cook 15–18 minutes until internal temperature reaches 160°F.
Apply the finishing butter. In the last 3–4 minutes of cooking, lay 1–2 rounds of the cilantro lime compound butter on top of each thigh. Close the lid and let the butter melt and baste the surface of the chicken. The fat will run down into the crust and the grill marks will glisten. This is the moment.
Rest and serve. Remove chicken from the grill when it reaches 165°F internal temperature. Let rest 5 minutes — do not skip this. The juices redistribute and the butter sets into a light glaze. Serve with extra compound butter on the side and lime wedges.
