Grilled Peanut Chicken and Broccolini Recipe Guide
Elevate simple ingredients with a rich, nutty sauce and effortless grilling technique.

The Story Behind This Amazing Grilled Peanut Chicken Recipe
Sometimes the best recipes come from those moments when you think you have nothing to cook with. This grilled peanut chicken and broccolini recipe was born from one of those pantry-raiding sessions that turned into something absolutely delicious. When you’re staring at a sparse refrigerator but have a handful of pantry staples and some broccolini waiting in the produce drawer, magic can happen.
This recipe proves that you don’t need a lengthy shopping list to create an impressive, restaurant-quality meal at home. The combination of Asian-inspired flavors with the smoky char from grilling creates a dish that’s both comforting and exciting. The peanut sauce serves double duty as both a marinade and a pasta sauce, making this a truly efficient one-bowl wonder that delivers maximum flavor with minimal fuss.
Essential Ingredients for Your Peanut Chicken Marinade
The secret to this recipe lies in the versatile sauce that transforms simple chicken breasts into something extraordinary. This isn’t just any marinade – it’s a complex blend of flavors that brings together the best of Asian cuisine with accessible pantry ingredients.
The Core Marinade Components
Olive oil forms the base of our marinade, providing the fat needed to carry flavors and help with grilling. Peanut butter – whether creamy or crunchy – adds richness and that distinctive nutty flavor that makes this dish so special. The beauty of this recipe is its flexibility; use whatever peanut butter you have on hand.
Soy sauce brings the essential umami depth that makes Asian-inspired dishes so satisfying. It adds saltiness and that deep, savory flavor that balances the sweetness from other ingredients. Honey provides natural sweetness that complements the peanut butter perfectly while helping to caramelize the chicken during grilling.
Flavor Enhancers and Aromatics
Barbecue sauce adds a subtle smokiness that pairs beautifully with grilling, while Worcestershire sauce contributes another layer of umami complexity. A few dashes go a long way in building that rich, savory foundation.
Fresh lemon juice brightens the entire marinade – though lime juice works equally well if that’s what you have available. The acidity helps tenderize the chicken while adding a fresh, citrusy note that cuts through the richness.
Cayenne pepper brings the heat – adjust according to your spice preference, or substitute with chili paste for a different type of warmth. Finally, fresh garlic adds aromatic depth that ties all the flavors together.
Preparing Your Peanut Sauce Marinade
Creating the perfect peanut sauce marinade is all about balance and personal preference. Start by whisking together all your ingredients in a bowl, combining the olive oil, peanut butter, soy sauce, barbecue sauce, honey, Worcestershire, lemon juice, cayenne, and minced garlic.
The key step that many home cooks skip is tasting and adjusting. Peanut sauce is highly personal – some prefer it sweeter, others like more heat, and some want extra tang from the citrus. Don’t be afraid to add more honey for sweetness, extra soy sauce for saltiness, more lemon juice for brightness, or additional cayenne for heat.
The Critical Reserve Step
Before marinating your chicken, pour off about one-third to one-half cup of the sauce into a separate container and refrigerate it. This reserved portion will become your pasta sauce later, and it’s crucial for food safety that it doesn’t come into contact with raw chicken.
Marinating the Chicken for Maximum Flavor
Place your chicken breasts into the remaining marinade, turning them to ensure complete coating. While the recipe works with two chicken breasts, you can easily scale up to four if feeding a larger crowd – there’s plenty of marinade to go around.
Ideally, let the chicken marinate in the refrigerator for at least two hours. This allows the flavors to penetrate the meat and the slight acidity from the lemon juice to tenderize the protein. However, life happens, and even a shorter marinating time will yield delicious results.
Preparing Your Vegetables for Grilling
While the chicken marinates, prepare your vegetables. Broccolini is the star vegetable here – it grills beautifully and has a more delicate flavor than regular broccoli, with tender stems that don’t require peeling.
Seasoning the Broccolini
Drizzle the broccolini with olive oil and season generously with salt and pepper. Toss to ensure even coating. The oil helps prevent sticking and promotes even browning, while the seasoning enhances the natural flavors.
Cut your onion into thick slices – these will hold together better on the grill and provide sweet, caramelized flavor that complements the peanut sauce beautifully.
The Grilling Process: Timing and Technique
Heat your grill pan over medium heat and drizzle with oil to prevent sticking. If you’re using an outdoor grill, that works perfectly too – the key is maintaining consistent medium heat.
Grilling Strategy
You have several options for grilling order. You can cook the chicken first, then add vegetables, or grill everything together if space allows. The important thing is managing cooking times appropriately.
Chicken needs to cook through completely, reaching an internal temperature of 165°F. This typically takes 6-8 minutes per side, depending on thickness.
Broccolini cooks much faster and requires careful attention. Turn it regularly and watch the color closely. You want beautiful char marks and some blackened edges, but avoid letting it burn. Don’t hesitate to remove it from the grill while the chicken finishes cooking.
Onions should become soft and golden brown, with lovely caramelized edges that add sweetness to the final dish.
Preparing the Pasta Component
While your proteins and vegetables grill, cook thin spaghetti or angel hair pasta according to package directions. These delicate pasta shapes work best with the peanut sauce, as they don’t compete with the other flavors and textures in the dish.
Drain the pasta well but don’t rinse it – you want some of that starchy pasta water to help the sauce adhere properly.
Final Assembly and Sauce Finishing
Once everything is grilled to perfection, it’s time for the final assembly. Take your reserved peanut sauce from the refrigerator and heat it in a small skillet until it just begins to bubble and caramelize. This cooking process intensifies the flavors and creates a glossy, restaurant-quality sauce.
Toss the hot pasta with the heated sauce, ensuring every strand is coated. The combination of hot pasta and warm sauce creates the perfect consistency.
Plating and Presentation
Create an appealing plate by starting with a portion of the peanut pasta as your base. Place a grilled chicken breast alongside, then arrange the broccolini and grilled onions artfully around the plate. The contrast of colors – the golden chicken, bright green broccolini, and caramelized onions – makes for a visually stunning presentation.
Finish with fresh cilantro leaves for a pop of color and fresh herbal flavor that complements the Asian-inspired flavors perfectly.
Serving Suggestions and Variations
This dish is delicious on its own, but consider offering some accompaniments. Extra soy sauce on the side allows diners to adjust saltiness to their preference. Lime wedges add fresh acidity that brightens each bite. If you used lime juice in the marinade instead of lemon, lemon wedges work equally well.
Recipe Variations
This recipe is endlessly adaptable. Try different vegetables like bell peppers, zucchini, or asparagus. Swap chicken thighs for breasts if you prefer dark meat. Add crushed peanuts for extra texture, or incorporate fresh herbs like Thai basil or mint for different flavor profiles.
Frequently Asked Questions
