Asado Chicken with Zucchini

This Asado chicken breast with sauteed lemon zucchini transforms ordinary chicken into a vibrant, flavor-packed meal that brings restaurant quality to your dinner table. The citrus marinade infuses the chicken with incredible depth while the tender zucchini soaks up all those savory juices.

I discovered this recipe during a summer when my garden was overflowing with zucchini. What started as a way to use up excess produce quickly became our family's most requested chicken dish. My teenagers who usually avoid vegetables actually ask for seconds of the zucchini.

Ingredients

• Chicken breast: boneless and skinless for quick cooking and healthy protein
• Zucchini: fresh and firm provides the perfect texture contrast to the chicken
• Garlic cloves: minced fresh is best for that aromatic punch
• Oregano: dried works perfectly in this marinade
• Smoked Paprika: the secret ingredient that adds depth and subtle smokiness
• Cumin Powder: brings an earthy warmth that complements the citrus
• Chicken stock: creates a more complex flavor base than using just oil
• Lemon juice: fresh squeezed brightens everything and tenderizes the chicken
• Onion Powder: provides savory notes without chunks of onion
• Chili Flakes: adjust to your heat preference
• Olive Oil: high quality makes a noticeable difference in flavor

Step-by-Step Instructions

Prepare the marinade:

Combine smoked paprika, cumin, chicken stock, lemon juice, onion powder, oregano, minced garlic, chili flakes, and olive oil in a medium bowl. Whisk thoroughly until everything is well incorporated. The marinade should have a vibrant reddish color and smell incredibly aromatic. This flavor base is what transforms ordinary chicken into something extraordinary.

Marinate the chicken:

Place chicken breasts in the marinade ensuring each piece is fully coated. Turn the pieces several times to maximize coverage. Cover the bowl with plastic wrap and refrigerate for at least 30 minutes but no longer than 4 hours as the acid in the lemon juice can start breaking down the proteins too much. If you're short on time, even 15 minutes will make a difference in flavor.

Cook the chicken:

Remove chicken from marinade and shake off excess but save every drop of that marinade. Heat a tablespoon of oil in a large skillet over medium-low heat until shimmering. Place chicken carefully in the pan and cook undisturbed for about 7 minutes until golden brown. Flip and cook another 7–8 minutes until internal temperature reaches 165ºF. The low and slow approach prevents tough, dry chicken. Transfer to a plate and cover loosely with foil to keep warm.

Prepare the zucchini:

In the same skillet, add your diced zucchini without cleaning the pan. Those browned bits from the chicken are pure flavor. Season with salt, pepper, and a pinch more chili flakes if desired. Sauté for 2–3 minutes until the zucchini begins to soften but still maintains some firmness. The zucchini should take on some color from the pan.

Finish with the sauce:

Pour the reserved marinade into the pan with the zucchini. This step is crucial as it creates a delicious sauce while ensuring food safety since it will cook thoroughly. Simmer for 3–4 minutes, stirring occasionally until the sauce thickens slightly and the zucchini is tender but not mushy. The sauce should coat the back of a spoon when ready.

This recipe reminds me of Sunday dinners at my grandmother's house where chicken was always the centerpiece but never boring. She taught me that the marinade makes all the difference and that splashing fresh lemon juice right before serving wakes up all the flavors like nothing else.

Make Ahead Options

The marinade can be prepared up to three days in advance and stored in an airtight container in the refrigerator. This makes weeknight cooking significantly faster. You can even place frozen chicken breasts directly into the marinade in the morning and by dinner time they will be thawed and fully flavored ready to cook. The completed dish reheats beautifully making it perfect for meal prep.

Serving Suggestions

While this dish is certainly complete on its own, pair it with fluffy couscous or crusty bread to soak up the delicious sauce. For a lighter option, a simple green salad dressed with lemon vinaigrette complements the flavors perfectly. During summer months, I love serving this alongside grilled corn on the cob for a seasonal feast that requires minimal oven time.

Ingredient Substitutions

No zucchini on hand? Yellow squash, bell peppers, or even asparagus work wonderfully in this recipe. The chicken breasts can be swapped for thighs, which actually provide even more flavor and forgiveness during cooking. For a dairy-free creamy finish, stir a tablespoon of coconut cream into the sauce during the final minute of cooking. Limes can substitute for lemons if that is what you have available, though the flavor profile will shift slightly toward a more tropical note.

Storage Tips

Store any leftovers in an airtight container in the refrigerator for up to three days. The flavors actually continue to develop overnight making this possibly even better the next day. To reheat, gently warm in a covered skillet over low heat with a tablespoon of water to prevent drying. For freezing, separate the chicken from the zucchini as vegetables tend to become mushy when frozen and thawed. Freeze the chicken in its sauce for up to three months and prepare fresh vegetables when serving.
