Ingredients

• 1.5 pounds boneless, skinless chicken breasts, cut into bite-sized pieces
• 2 tablespoons olive oil or avocado oil
• 1 large head of broccoli, cut into florets
• 1 medium red bell pepper, thinly sliced
• 1 medium yellow onion, thinly sliced
• 2 cloves garlic, minced
• 1 teaspoon grated fresh ginger
• 1/2 cup creamy peanut butter (natural, unsweetened preferred)
• 1/4 cup low-sodium soy sauce or tamari
• 2 tablespoons rice vinegar
• 1 tablespoon honey or maple syrup (optional, for sweetness)
• 1-2 teaspoons sriracha or chili garlic sauce (adjust to your spice preference)
• 1/4 cup water or chicken broth
• 1 tablespoon sesame oil
• Optional garnishes: chopped peanuts, sesame seeds, sliced green onions

Instructions

1. In a medium bowl, whisk together the peanut butter, soy sauce, rice vinegar, honey (if using), sriracha, and water or chicken broth until smooth and well combined. This is your luscious peanut sauce. Set aside.
2. Heat 1 tablespoon of olive oil in a large skillet or wok over medium-high heat. Add the chicken pieces in a single layer (you may need to do this in batches to avoid overcrowding). Cook for 3-4 minutes per side, until browned and cooked through. Remove the chicken from the skillet and set aside.
3. Add the remaining 1 tablespoon of olive oil to the same skillet. Add the broccoli florets, red bell pepper, and yellow onion. Stir-fry for 5-7 minutes, or until the vegetables are tender-crisp. You want them to still have a slight bite.
4. Push the vegetables to the side of the skillet, creating a well in the center. Add the minced garlic and grated ginger to the well and cook for about 30 seconds until fragrant, stirring constantly.
5. Pour the prepared peanut sauce over the vegetables and chicken. Add the cooked chicken back into the skillet. Stir everything together to coat evenly.
6. Cook for another 2-3 minutes, stirring frequently, until the sauce has thickened slightly and is bubbling.
7. Stir in the sesame oil and toss to combine.
8. Serve immediately, garnished with chopped peanuts, sesame seeds, and sliced green onions, if desired. This stir-fry is fantastic served over brown rice, quinoa, or cauliflower rice for an extra boost of nutrients and fiber.

Chef’s Secret Tip

For an extra depth of flavor in your peanut sauce, lightly toast your peanuts before making the peanut butter if you are using whole peanuts. If using store-bought peanut butter, a tiny pinch of toasted sesame seeds blended into the sauce can mimic this toasted nut flavor beautifully. Also, don’t be afraid to add a splash more water or broth if your sauce becomes too thick during cooking; consistency is key!

Pro Tips for the Perfect Stir-Fry

Chicken Preparation

When cutting your chicken breasts, aim for uniform, bite-sized pieces. This ensures even cooking and makes for a more enjoyable eating experience. For an even more tender chicken, you can marinate the chicken pieces in a tablespoon of soy sauce and a teaspoon of cornstarch for about 15-20 minutes before cooking. This creates a lovely, velvety texture once cooked.

Vegetable Variety

While broccoli, bell peppers, and onions are a classic combination, don’t hesitate to experiment! Snow peas, snap peas, carrots, mushrooms, or even thinly sliced zucchini all work wonderfully in this stir-fry. Just ensure they are cut to a similar size for consistent cooking times. If using denser vegetables like carrots, you might want to add them a few minutes before the softer vegetables.

Spice Level Control

The sriracha or chili garlic sauce is your main tool for heat. Start with the smaller amount recommended and taste the sauce before adding the chicken and vegetables. You can always add more heat, but you can’t easily take it away! If you prefer a milder dish, simply omit the sriracha or use a very small amount. For those who love it extra spicy, feel free to increase the amount or add a pinch of red pepper flakes.

Peanut Butter Choice

Opting for a natural, unsweetened peanut butter will give you the best control over the flavor and sweetness of your sauce. If your peanut butter is very stiff, you might need to add a little more liquid (water or broth) to achieve the desired sauce consistency. Stirring the peanut butter well before measuring is also important, as the oil can separate.

The Wok or Skillet

A wok is ideal for stir-frying due to its shape, which allows for efficient heat distribution and easy tossing of ingredients. However, a large, heavy-bottomed skillet will work perfectly well. The key is to ensure your pan is hot before you start cooking and to avoid overcrowding it, which can lead to steaming rather than searing.

Serving Suggestions

This stir-fry is incredibly versatile. Serve it as is for a low-carb, high-protein meal. For those who enjoy a grain base, it pairs beautifully with steamed brown rice, white rice, or even quinoa for an added protein and fiber boost. For a lighter option, cauliflower rice is an excellent choice.

Frequently Asked Questions (FAQs)

Can I make this stir-fry ahead of time?

While stir-fries are best enjoyed fresh, you can prepare some components in advance. The peanut sauce can be made and stored in an airtight container in the refrigerator for up to 3 days. You can also chop all your vegetables and chicken ahead of time. However, to maintain the best texture, it’s recommended to cook the stir-fry just before serving. Reheating can sometimes make the vegetables a bit soft.

What kind of peanut butter is best for this recipe?

Natural, unsweetened peanut butter is highly recommended. It allows you to control the sweetness and saltiness of the sauce more effectively. Brands like Skippy Natural, Jif Natural, or any store brand natural peanut butter will work well. If you use a sweetened peanut butter, you may want to reduce or omit the honey/maple syrup.

How can I make this recipe vegetarian or vegan?

To make this a vegetarian or vegan dish, replace the chicken with firm or extra-firm tofu. Press the tofu to remove excess water, then cut it into cubes and pan-fry or bake it until golden brown and crispy before adding it to the stir-fry. Ensure your soy sauce is tamari (if gluten-free) and use maple syrup instead of honey. For a vegan protein boost, consider adding edamame or chickpeas.

My peanut sauce is too thick. What should I do?

This is a common issue, especially with natural peanut butters. Simply add more water or chicken/vegetable broth, a tablespoon at a time, whisking continuously until you reach your desired sauce consistency. You can also add a splash of rice vinegar or soy sauce if needed to adjust the flavor balance.

Can I use chicken thighs instead of breasts?

Absolutely! Chicken thighs are often more forgiving and can stay juicier than breasts. They are also a great source of protein. Simply trim any excess fat and cut them into bite-sized pieces. The cooking time might be slightly longer than chicken breasts, so ensure they are cooked through before serving.

Is there a way to make this spicier?

Yes! For extra heat, you can add more sriracha or chili garlic sauce. You can also incorporate a pinch of red pepper flakes into the sauce mixture or sauté them with the garlic and ginger. A thinly sliced fresh chili pepper added to the stir-fry along with the other vegetables can also provide a fresh, fiery kick.
